无线电知识学习中,看看俺的工作台

还差一只LCR表,慢慢搜寻中,呵呵!

说明书可以轻易下载到，但是要用IRT4520这几个关键字搜索。具体指标如下：

以下介绍了，耳内测温的原理，原来耳鼓和大脑控制体温的中枢神经都是同一血液供给，所以耳温测量比腋下、直肠和体表测温都精确。

这个耳温计也是用了红外线的原理进行测量。精度在0.1摄氏度。

Why measure in the ear?

The goal of thermometry is to measure core body temperature

1

which is the

temperature of the vital organs. Ear temperatures accurately reflect core body

temperature

2

, since the eardrum shares blood supply with the temperature

control center in the brain

3

, the hypothalamus. Therefore, changes in body

temperature are reflected sooner in the ear than at other sites.

• Axillary temperatures measure skin temperature and therefore, may not be a

reliable indicator of core body temperature.

• Oral temperatures are influenced by drinking, eating and mouth breathing.

• Rectal temperatures often lag behind changes in core body temperature and

there is a risk of cross-contamination.

# This file is sourced from the linux-restricted-modules-common init
# script and is used to disable the link-on-boot feature, one module
# at a time.  This can be useful if you want to use hand-compiled
# versions of one or more modules, but keep linux-restricted-modules
# installed on your system, or just to disable modules you don't use
# and speed up your boot process by a second or two.
#
# Use a space-separated list of modules you wish to not have linked
# on boot.  The following example shows a (condensed) list of all
# modules shipped in the linux-restricted-modules packages:
#
# DISABLED_MODULES="ath_hal fc fglrx ltm nv"
#
# Note that disabling "fc" disables all fcdsl drivers, "ltm" disables
# ltmodem and ltserial, and "nv" disables both the nvidia drivers.
# You can also name each module individually, if you prefer a subset.
 
DISABLED_MODULES="ath_hal"

2.打开终端依次执行以下命令行

sudo apt-get update

sudo apt-get install build-essential

wget 'http://snapshots.madwifi.org/madwifi-hal-0.10.5.6-current.tar.gz'

tar zxvf madwifi-hal-0.10.5.6-current.tar.gz

cd madwifi-hal-0.10.5.6-r3835-20080801

cd madwifi-hal-0.10.5.6-r3835-20080801

make clean

make

sudo make install

sudo reboot 

好了，您的ubuntu  8.04可以使用无线上网了

是元件的问题，拆开它，

左下带白色按键的元件有问题，想法拆开它，把里面弹簧片向下的凸面用起子往上面推一推，试一下，问题应该可以解决了！
