准备回家
今天上午向隋老师和曹老师请了假，准备回家喽~~~
先把手头上的的工作梳理一下以便开学后顺利展开工作：
1、氧气变送器：原理图，PCB已画好，尚未给曹老师审核
2、Freon变送器：原理图已画好，尚未对PCB布局
不写了，还是休息下吧，哈哈
三句半-光纤实验室08年元旦晚会节目
我们大家台上站，这回咱说三句半，说得不好怎么办？——凑合着看。
各位老师同学好，新的一年来到了，二年级组凑热闹，——搞笑。
自编自演不在行 不管听的爽不爽 还要请您多捧场，——鼓掌。(齐:鼓掌)
老师同学齐来了，平时很少能看到，喜笑颜开聚一起， —-热闹！
今天实验室庆元旦，高高兴兴到零点，美酒佳肴摆满桌， —-开饭！
叫声诸位别着急，先看节目听歌曲，举起酒杯给大家， —-道喜！
实验室今年好事多，佳音喜讯一大摞，我们台上作总结， —-快说！
三句半
各位同学晚上好 欢迎大家来指导 不管说得好不好 别跑
我们四个台上站 有盆没锣三句半 目的只有only one 添乱

固定资产申报的流程
一、填写“山东大学固定资产购置申请表”，并报设备处审批。
二、填写“山东大学仪器设备登记表”，并找李明老师签字。去签字时注意携带借条。
三、持设备处审批后的“山东大学固定资产申请表” 和“山东大学仪器设备登记表”去4号楼找王文光老师，几天后从王老师处领回相应资料。
四、从王文光老师处领回资料后，去院办公室盖章，然后便可以去财务处报账了。
Optical Fiber Sensor and my subject FBG
As a new technology developed with Fiber and Communication in 1970s, Optical Fiber Sensor technology was obtaining the fast development in recent years, and the fiber grating technology also benefits from his development. Fiber Brag Grating Sensor is one kind of wave length modulation optical pickoff. It contains survey and transmits two kinds of functions, and takes the optical fiber as the transmission medium. The light wave transmission characteristic can be changed with temperature, stress, vibration, humidity and other environment parameter. Compared with the traditional electrical sensors, the fiber grating sensors has lots of good abilities, such as: thermostable, anticorrosive, the corrosion resistance, light, easy to integrate, the essence guards against explosions, and anti-electromagnetic interference. [1][2]
In 1978, K. O. Hill and his partner found the photosensitivity in optical fiber and from then on, the fiber grating sensor has been developed rapidly. In particular in the last few years, along with the machine which can be used to produce fiber grating become more and more exactly, the people become more interested in optical fiber sensors. So the optical fiber grating as an important modern sensor was widely used in large-buildings, aviation, ships, electricity, coal mine and petroleum. Meanwhile, the wavelength demodulation techniques have also developed rapidly. Currently, a lot of wavelength detection methods, including spectroscopy method, matching grating, tunable Fabry-Perot, Non-balanced Mach-Zehnder tracking, Tunable Laser, etc. [3]
My research contains, Fiber Bragg grating, as one of the most developed passive fiber devices, has function of reflection to very wavelength, and its wavelength changed with temperature and strain, and has excellent filter properties, temperature and strain response, which is a novel fiber photonic device with rapid development in these years and has broad application in the fields of fiber communication and fiber sensor. Fiber Bragg grating (FBG) sensor is a new type of sensor, which has the advantages of resistance to high voltage, lightweight, low loss, non-sensitivity to the environment, small volume, high Signal-to-Noise and high sensitivity, anti-electromagnetism, better insulation and large bandwidth, being used as sensor and transmitting medium at the same time, and it is more easy to realize multipoint or distributed measure. Yet, the new technologies have been born only few years, so they should be researched and developed more deeply.
