【求助】求助 翻译中遇到的困难

还有一处，Fixed vise jaw:
这个也不太懂，请好心人帮忙

FIG. 2 Relationship of Vise, Specimen, and Striking Edge to Each
Other for Test Method E
vise在ASTM D256中也出现了多次，请高手指教

The machine shall consist of a massive base on which is
mounted a vise for holding the specimen and to which is
connected, through a rigid frame and bearings, a pendulumtype
hammer.
这里也出现了vise
实在搞不清楚是啥意思。。。

vise seems a tool for clamping


The right portion is "Fixed vise jaw"

我不是高分子专业的，也没接触过ASTM，只能给你一些参考意见：

这里的vise应该是指一种钳子，jaw是指钳子上的夹子。这种钳子上的夹子可以用螺丝或杠杆固定，这里的fixed vise jaw就是已经把夹子位置固定好的钳子。

楼主可以看看www.answers.com上面的解释：
vise:A clamping device, usually consisting of two jaws closed or opened by a screw or lever, used in carpentry or metalworking to hold a piece in position.

遇到意思不好理解的专业词汇时楼主可以去上面的网站,或者CNKI翻译助手等专业词典寻求解释(英语好的话看英英词典最好),不要看金山词霸,金山词霸收录的专业词汇太少了.如果你觉得这个不懂的词可能是仪器设备之类有形的东西,可以以它为关键词用google搜索图片.我以"fixed vice jaw"为关键词搜索图片,搜索的结果证实了我的解释是对的.至于专业词典,本版置顶的帖子里介绍了很多,楼主可以去看看,我最推荐的有三个:

D256    Standard Test Methods for Determining the Izod Pendulum Impact Resistance of Plastics 塑料及电绝缘材料的抗冲击性的测试方法

Izod is a person who developed this test method (similar to Rockwell who developed the Rockwell Hardness Test 洛氏硬度测试方法)

I believe that there may be corresponding GB equivalent to “Test Method A—Reversed Notch Izod”, then you may refer to that GB; or alternatively, upload the details of “Test Method A—Reversed Notch Izod” for our discussion to find out a proper translation.

notch就是缺口,一般写作notched
有些方法试样没有缺口的
reverse是反向的意思
如#ISO 180/1U就是将试样反向夹紧的

实在太感谢大家的热心帮助！！！
我还有个问题想请教：
In the round robin,each laboratory tested ten specimens of each material.
请问这里的robin 是啥意思呢？

Round Robin is a short form of Round Robin Test => 循環對比測試

The explanation of round robin can be found from http://www.answers.com/ as recommended by happyjyl at 6/F with the key words “Round Robin Test”.
