To measure the studio via sound level meter, and questionnaire, exam pure tone audiometric test for 84 staffs of broadcast, 50 staffs of administration. The age of these two groups are 41.9 and 40.2 years old.

本次研究对象以台湾北部广播业劳工为对象共134名：播音员84人及行政人员50人，进行问卷调查，以噪音频谱分析仪测量广播室音量，再以纯音听力检查仪器进行劳工的听力检查。

Results①In non-vibration group, the peak of temperature appeared at operation 3min; in vibration group,the temperature were increasing gradually as the peak appeared at evacuating 3min .②vibration group had better significant and persistent calorigenic effect than non-vibration group. ConclusionVibration massage apparatus has the validity of heightening temperature.

结果①不同测量时间对受试者局部温度有影响（P.05），空置组中温度升高在空置3 min后即刻尤为明显，尔后温度呈逐渐下降趋势，而振动组中随着时间的增加，背部温度不断升高，在振动后撤离仪器3 min达到峰值；②空置组和振动组都能使局部皮肤温度有不同程度的升高，但振动组比空置组产热效应更显著，而且更为持久。

With the development of aerial and aerospace industry, many aerial and aerospace components are needed to work in some terrific conditions (such as high temperature, high pressure, vacuum and toxic gas). For this purpose, many new materials (such as carbonylic composite material and ceramics) have been manufactured. So the study of material character in the terrific conditions, especially the precise measurement of the strain and stress, becomes very urgent.

The experimental results indicate that the instrument error can be more completely separated using the researched method in the paper. So, the precision measurement for the cylindricity error can be realized.

实验结果表明，本文提出的圆柱度误差分离及重构方法可以比较完整地分离出仪器误差，从而实现圆柱度误差的精密测量。

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.
