继续“忽悠”(转贴)
编者按:
这是我1993年初购买巴尔达相机时所带的说明书,现在贡献给大家,特别是喜欢“小巴”的朋友。
我国首次引进生产的世界级超小型高性能135照相机
巴尔达CS35、CE35系列电子程序自动曝光袖珍照相机和CF18型计算机控制专用闪光灯,是由中德合资长江--巴尔达照相机器材制造有限公司从联邦德国的老牌照相机生产专业厂家--巴尔达公司引进生产的。是现代照相机设计、工艺、材料与德国传统精密制造技术的完美结合。德国巴尔达公司研制生产的这种袖珍相机于八十年代刚问世,便在世界照相机市场上引起轰动。一九八四年科隆公司国际照相器材博览会上被评为最佳袖珍照相机,一九八六年被德国《摄影杂志》评为世界五种超小型照相机极品之一。
巴尔达照相机重量仅有150克,体积仅为103×62×32mm,可装入衬衣口袋,是目前世界上最轻最小的135照相机之一。巴尔达照相机采用了电子程序自动曝光系统,使用了两只不同数的CdS光敏电阻串联测光,多点补偿,具有极宽广的自动曝光范围:EV0-EV17。电子程序快门由f/2.8、8秒连续变化到f/16、1/500秒。自动曝光精度均控制在±1EV之内,常用曝光范围EV6-EV15,其曝光精度则控制±0.3EV以内,特别适合曝光精度要求苛刻的彩色反转片的拍照。此外,巴尔达照相机还保留有一档机械快门:f/16、1/500秒,以作为强光下无电池时的应急手段。程序自动曝光曲线如图所示。
巴尔达相机的镜头是由德国巴尔达公司提供,为四片三组天塞型后置光栏结构。由于采用高折射率,低色散的超级钢系玻璃材料和新的制造工艺,所以亮度分布均匀,球差、色差、象散和畸变都得到了很好的校正。解像率达到了德国标准的要求,超过中国一级镜头标准。整个画面像质均匀,层次分明,彩色还原效果逼真,低对比效果也很好,放大到24英寸以上的照片仍然十分清晰。
巴尔达相机由多达35种零件组成。采用了独特的行星轮系实现镜头的伸缩,定位精确可靠。折叠式前盖可保护镜头、测光传感器和取景器。关上前盖即可切断电源,并可锁住快门释放钮的保险装置。巴尔达相机具有明亮的取景器。在取景器内设有两只LED发光管显示“OK”与“ ”,以帮助测光。调焦系统既可以利用调焦圈上距离标尺作手动精确对焦,也可以利用取景器内设的快速区域对焦指示系统对焦。巴尔达相机还设有独创的方便快捷的逆光补偿开关和工作可靠的拍摄指示系统。CS35型相机还设有独特的耗电极低的电子自拍系统。
巴尔达相机的另一大特点是配有专用的CF18型计算机控制闪光灯,可实现自动闪光和自动调光闪光摄影。ASA100时,其最大闪光指数GN=18,其发射光谱与日光光谱极为接近。CF18闪光灯与CS35、CE35系列电子程序自动曝光相机相结合,即可实现全天候的自动曝光摄影。
巴尔达CF18型闪光灯持续时间可以从1/30000秒到1/500秒之间由计算机根据被摄物体的亮度与之匹配。实现自动调光摄影。闪光灯与相机之间设有快速连接装置,装卸极其快捷。当闪光灯与相机连接在一起时,双方的电气与机械接口随即接通,构成一个有机的整体。此时,闪光灯能根据被摄物体距离远近调整,而对照相机传输f/2.8和f/5.6两个工作光圈,实现闪光摄影模式。同时,照相机能根据被摄物体亮度的大小,而自动确定闪光灯是否闪光,实现自动闪光摄影。此外,当关上相机前盖时,闪光灯工作开关也同时会被自动切断,以避免电池浪费电能。
由于巴尔达系列相机具有成像质量高,曝光精确,功能齐全,操作简便可靠,体积小,重量轻等突出特点,作为专业相机,深受摄影界和新闻界的亲睐,同时,又不失为家庭生活、旅游用照相机的高档珍品。
巴尔达系列相机和闪光灯的机身用德国拜尔公司生产的碳纤维增强工程塑料注制,坚固异常。镜头、光学元件、快门、电子元器件由德国蔡司(Zeiss)、罗莱(Rollei)、西门子(Siemens)等公司提供。精密机械零件(包括镀金材料和坡莫合金材料),由瑞士提供。
巴尔达相机设计、制造、检验均执行西德DIN标准,整机验收按罗莱公司标准执行。

DSP来了(转载)
作者:张国斌Silicon Laboratories 近日发布了全球首款涵盖短波、长波、调幅和调频四波段单芯片收音机芯片,进一步扩大了其广播音频产品阵容。这款高效能Si4734/35芯片包含从天线输入到音频输出等所有接收机功能,其体积和解决方案元器件数比现有产品减少超过九成。
"目前收音机市场每年有几千万的量级,而且主要制造商集中在深圳地区,所以我们选择在深圳地区发布这款产品。" Silicon Labs产品营销经理Shahram Tadayan指出,"其实收音机虽然有几十年的历史,但是其芯片发展近20年来处于几乎停滞不前的地步,在我们发布这款产品之前,还没有哪家公司能设计出如此小集成度如此高的芯片。"
Si4734/35采用小巧的3 x 3毫米封装,不仅简化现有的短波与长波收音机设计,还能为手机和MP3播放机等现有消费电子产品增加短波与长波接收能力,使中国更多消费者能收到短波与长波广播内容。
Shahram表示Si4734/35可以涵盖从153kHZ的长波到108MHz调频波段,并可以支持64-76MHz延伸波段,他表示目前全球有数以百计的短波电台,可以让几千英里外的听众收听到节目,而且短波收音机在中国应用还是比较广泛的,在电台数目比较少的农村地区可以利用它收听新闻。就长波应用而言,他表示欧洲在欧洲很流行,常用于运动节目广播。
Shahram表示这款高集成度芯片带给制造商的一大好处是可以大大降低最终产品所需的外部元件数量,相比传统方案100多个外部元件的layout,这款新芯片只需要2个外部电容。而且因为内部有DSP,它可以实现超快速自动搜台,并有很好的通道隔离度和灵敏度,此外,它还可以提供立体混音,能提供模拟和数字音频输出。
他特别强调,Si4734/35可以缩短设计时间,让客户更快在市场上推出更高质量的产品。Si4734/35采用内置DSP的专利数字低中频架构,它能提供传统模拟架构产品无法做到的各种功能和更高效能。这些接收机芯片可于所有支持频带内提供完全自动化的数字调谐能力,包含1kHz步进频率和可选择式通道带宽滤波器以实现最佳音质。另外,Si4734/35系列不必使用需要工厂调整的元器件,这能进一步提高可靠性和降低制造成本;相形之下,现有接收机芯片最多需要三个阶段的人工调整。
他现场演示了基于该芯片的收音机搜索短波电台的效果,仅需数秒的时间,就搜索到了30多个短波电台。他还表示该芯片超强的灵敏度可以让收音机收听到许多信号微弱的校园广播信号,这是其他竞争对手不具备的优势。
他还指出,该芯片有很好的选择性,让收音机只接收目标电台信号。其优异的频道选择能力和高度线性的前端电路则让消费者在拥挤的广播环境里收听更多电台,这些功能对有数百家合法电台分散在广大频率范围内的短波频带很重要。
图1:Si4734/35频带示意图为了支持客户的方案升级,Silicon Labs整个收音机芯片系列都采用了相同的管脚布局,这样可以让客户方便升级目前已有的方案。
图2:和传统方案相比,新方案节省了大量的电路板空间Shahram表示目前手机、MP3还多只能接收调频节目,未来会有收听短波、调幅的需求,所以,该芯片有很好的前景,目前Si4734/35已通过EN55020认证,Si4735则整合了调频RDS译码功能,可为听众提供电台和歌曲名称。
图3:Si4734/35芯片框图对于未来产品规划,他表示目前由于DAB应用还不是特别热,所以目前公司还无意进军这个领域,他表示Silicon Labs已经占据了中国地区低端收音机市场30%~40%的份额,未来公司将进军手机、MP3市场,并继续做大收音机市场。
图4:搜索电台界面Silicon Labs近日收购了位于深圳的源核微电子技术公司(Sourcecore),该公司董事黄云腾博士表示:"收购后的公司改名委芯科科技有限公司,将成为Silicon Labs在中国的研发中心,将致力于提供芯片设计和系统设计支持服务,要把Silicon Labs的先进技术和本次应用结合起来。"针对这款新发布的产品,他表示公司将微本地客户提供全套解决方案,并开发新的应用,但他未透露是哪些具体新应用。

世界最强大国家的基石
The Declaration of Independence
IN CONGRESS, JULY 4,
1776 THE UNANIMOUS
DECLARATION OF THE
THIRTEEN UNITED
STATES OF AMERAICAWhen in the course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the laws Nature and Nature’s God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that they are among these are life, liberty and the pursuit of happiness. That to secure these rights, governments are instituted among them, deriving their just power from the consent of the governed. That whenever any form of government becomes destructive of these ends, it is the right of the people to alter or to abolish it, and to institute new government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. Prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experience hath shown that mankind are more disposed to suffer, while evils are sufferable, than t right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same object evinces a design to reduce them under absolute despotism, it is their right, it is their duty, to throw off such government, and to provide new guards for their future security. Such has been the patient sufferance of these Colonies; and such is now the necessity, which constrains them to alter their former systems of government. The history of the present King of Great Britain is usurpations, all having in direct object tyranny over these States. To prove this, let facts be submitted to a candid world.
He has refused his assent to laws, the most wholesome and necessary for the public good.
He has forbidden his Governors to pass laws of immediate and pressing importance, unless suspended in their operation till his assent should be obtained; and when so suspended, he has utterly neglected to attend them.
He has refused to pass other laws for the accommodation of large districts of people, unless those people would relinquish the right of representation in the Legislature, a right inestimable to them and formidable to tyrants only.
He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their public records, for the sole purpose of fatiguing them into compliance with his measures.]
He has dissolved representative houses repeatedly, for opposing with manly firmness his invasion on the rights of the people.
He has refused for a long time, after such dissolution, to cause others to be elected ; whereby the legislative powers, incapable of annihilation, have returned to the people at large for their exercise; the State remaining in the meantime exposed to all the dangers of invasion from without and convulsion within.
He has endeavored to prevent the population of these states; for that purpose obstructing the laws of naturalizing of foreigners; refusing to pass others to encourage their migration hither, and raising the condition of new appropriations of lands.
He has obstructed the administration of justice, by refusing his assent of laws for establishing judiciary powers.
He has made judges dependent on his will alone, for the tenure of their office, and the amount and payment of their salary.
He has erected a multitude of new officers, and sent hither swarms of officers to harass our people, and eat out our substances.
He has kept among us, in times of peace, standing armies without the consent of our legislatures.
He has affected to render the military independent of and superior to the civil power.
He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our laws; giving his assent to their acts of pretended legislation.
For quartering large bodies of armed troops among us;
For protecting them, by a mock trial, from punishment for any murder which they should commit on the inhabitants of these States.
For cutting off our trade with all parts of the world;
For imposing taxes on us without our consent;
For depriving us in many cases, of the benefits of trial by jury;
For transporting us beyond seas to be tried for pretended offenses;
For abolishing the free systems of English laws in a neighboring Province, establishing therein an arbitrary government, and enlarging its boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule these Colonies;
For taking away our Charters, abolishing our most valuable laws, and altering fundamentally the forms of our governments;
For suspending our own Legislatures, and declaring themselves invested with power to legislate for us in all cases whatsoever.
He has abdicated government here, by declaring us out of his protection and waging war against us.
He has plundered our seas, ravaged our coasts, burnt our towns, and destroyed the lives of our people.
He is at this time transporting large armies of foreign mercenaries to complete the works of death, desolation and tyranny, already begun with circumstances of cruelty and perfidy scarcely parallel in the most barbarous ages, and totally unworthy the head of a civilized nation.
He has constrained our fellow citizens taken captive on the high seas to bear arms against their country, to become the executioners of their friends and brethren, or to fall themselves by their hands.
He has excited domestic insurrection amongst us, and has endeavored to bring on the inhabitants of our frontiers, the merciless Indian savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes, and conditions.
In every stage of these oppressions we have petitioned for redress in the most humble terms: our repeated petition have been answered only by repeated injury. A prince whose character is thus marked by every act which may define a tyrant is unfit to be the ruler of a free people.
Nor have we been wanting in attention to our British brethren. We have warned them from time to time of attempts by their legislature to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpation, which would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our separation, and hold them., as we hold the rest of mankind, enemies in war, in peace friends.
We, therefore, the Representatives of the United States of America, in General Congress assembled , appealing to the supreme Judge of the world for the rectitude of our intentions, do, in the name, and by authority of the good people of these Colonies, solemnly publish and declare, That these United States Colonies and Independent States; that they are absolved by from all allegiance to the British Crown, and that all political connection between them and the State, they have full power to levy war, conclude peace, contract alliances, establish commerce, and to do all other acts and things which Independent States may of right do. And for the support of this declaration, with a firm reliance on the protection of Divine Providence, we mutually pledge to each other our lives, our fortunes, and our sacred honor. -

海量照片时代
无论你玩什么,其实都是吃饱了撑的,没事干。
胶片如今衰落了,数码旗帜高高飘扬,DC/DSLR几乎人手一只,每天肆意的按动廉价快门,照片编号到顶了又重新启动。
海量照片时代的来临,生活变成了一张张数码照片的拼图。
然而,这数量正让我失去感觉,失去感觉

吃土豆
土豆一直是我钟爱的食品,尤其是煮汤,味道很好,而且土豆这种东西营养很丰富。但是千万少吃油炸的土豆,油炸土豆不仅营养损失大,而且油炸土豆的热量是煮土豆的几十倍,不利于健康。
土豆的品种很多,最好吃的是那种表皮很粗糙,像有一个个小裂纹的,表皮光滑的土豆味道不怎么好。
在云南出名的还有两种土豆,昆明人俗称“紫洋芋”和“宣威小洋芋”,都是很不错的品种,尤其是切片以后佐以“糟辣子”煮汤,味道极其鲜美。
昨天在家又吃了土豆汤,最后锅底有一些已经煮成糊状的土豆泥,味道很好,这使我想起了好多苏联电影上俄国人吃土豆泥的情景。我想他们之所以把土豆做成泥吃是有一定原因的,在俄国冬季天气极其寒冷,为了尽快的使身体消化食物转变成热量,食物当然是越容易消化越好,所以吃块状的土豆汤,不如吃土豆泥,呵呵这个是我的理论。
