Experimental accuracy and repetition of FBG temperature sensitivity and compensation were discussed.have selected several materials which has bigger coefficient of expansion to do packaging components, have made many temperature experiments, there have not flaws, such as aging, crackle, absciss layer, packaging materials have good temperature sensitivity and compatibility with optical fiber;have designed the simple and practical packaging components, have performed a serials of experiments about accuracy and repetition of FBG wave-length, have obtained the first step conclusion;have analyzed the result and made comparison between the result of different experiment, have summarized the best packaging effect and several rules to reduce mistskes.

本文所做的主要工作包括以下几个内容：一、选取了常见的热膨胀系数大的材料制作封装元件，经过多次一80℃到80℃反复测试，封装元件没有出现老化开裂、封装裂纹、空洞、离层等缺陷，封装材料具有良好的温敏稳定性及复用性，与光纤相容性较好；二、对光纤光栅进行简单、实用的封装处理，就封装效果的优劣性、波长测量的准确度、重复性和封装时产生的波长损失等方面进行了一系列的实验，得出了初步的结论；三、对温敏和温度补偿式封装的实验数据进行了详细的分析和对比，从数字上对温变过程中光纤光栅中心波长的改变及温变曲线进行了定量的分析，在大量实验数据分析结果的基础上，总结出哪种材料封装效果更好，以及如何有效的减小实验误差。

The roof abscission layer is the biggest security hidden danger in bolting support tunnel.

顶板离层是锚杆支护巷道最大的安全隐患之一。

This review focuses on the advances in the molecular biology study of abscission zone development and organ shedding in Arabidopsis, rice, and tomato.

本文重点综述拟南芥、水稻、番茄等模式植物中离区发育和器官脱落的分子生物学研究进展，并对今后的研究方向做了简要展望。

Tyloses are often found in injured tissue, older wood, and below an abscission layer, and can completely block the conducting vessel.

受损害的组织、衰老的木材和离层下方的位置常发现侵填体，这可以完全阻塞负责运输的导管系统。

Abscission occurs at specific sites called abscission zones.

器官脱落发生的区域叫做离区。

Absence without official leave or leaving one's position without proper reason and approval from departmental director at working hour for 60mins to 120mins or cause the economic loss of 10000 RMB to 20000 RMB

工作时间内，未经部门领导允许，擅离职守无故脱离工作岗位，在60分钟以上120分钟以下，或给公司造成的损失在10000元至20000元者

ABSOLUTE ALTITUDE, The actual distance the aircraft is above the ground.

绝对高度，飞机离地面的实际距离。

As a measure of risk, mean absolute deviation is better than variance in a sense.

作为度量风险的标准，绝对离差比方差更为合适。

Two fund separation is found in mean absolute deviation portfolio choice model.

实证分析还表明，绝对离差模型中有近似的两基金分离现象存在。

Earlier, when we calculated the range, the interquartile deviation, and average absolute deviation, the answers were expressed in the same units as the data itself.

当我们计算极差，四分点离差和平均绝对偏差时，答案的计量单位与数据单位量相同的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
