Foamed plastic materials containing many small cells which are not connected are good cryogenic insulating materials . 塑料泡沫材料含有许多互不相通的小气囊,是优良的低温绝缘材料。
"shock proof" insulated testing handles should be provided with the tester, to assure adequate protection for the operator . 这种试验器应装有“耐冲击”的绝缘试验柄,以保证对操作人的可靠防护。
We should pursue agreement and attempt to insulate it as much as possible from the ups and downs of conflicts elsewhere . 我们应该谋求达成协议,并且应该试图尽可能把它同别处此伏彼起的冲突分隔开来。
A way to circumvent the problem is to fabricate devices in small islands of silicon on an insulating substrate as shown in fig. 32 . 消除这个问题的一个方法是把器件制造在绝缘衬底的硅岛上,如图32所示。
Generally, one approximates a blackbody in the laboratory by a hollow insulated enclosure which contains a small hole in the wall . 一般地说,人们在实验室中用壁上带有一个小孔的空心绝缘壳来近似模拟一个黑体。
