1.You should now be able to lift the lower end of the PCB and pull it out in a flat angle.
您现在应该可以解除低端的PCB拉在一个平面的角度出来。
2.It still, however, seems to work as a transcription factor. The result is fish that are more or less immune to PCB poisoning.
这仍然跟转录因子的作用有关，结果表明，是这些鱼或多或少具备了PCB免疫力。
3.It has been designed as single layer PCB, and therefore it is really easy to be produced at home.
它被设计为单层PCB，因此非常容易在家自制。
4.The surface topography of PCB manifests self similarity, which shows that the material fracture possesses fractal characteristics.
电路板外观形貌具有自相似性，表现出分形的特征。
5.But the protein does not seem to mind. It appears to work equally well, whether or not it has PCB passengers on board.
且蛋白质似乎并不介意，因为作用是相同的，无论PCB有没有在其中。
6.The shortened version of AHR does not bind nearly so easily to PCBs. It still, however, seems to work as a transcription factor.
这个缩减版本的AHR难以和PCB结合，不过看来依然能发挥转录因子的作用。
7.Printed-circuit boards used to be works of art, and the PCB designer was an artist as well as a technician.
在过去，一块印刷电路板就是一份艺术品，印刷电路板的设计人员不仅仅是一名技术人员还是一位艺术家。
8."We believe that at least 95percent of the PCBs in the dredge area will be removed, " she said in atelephone call with reporters.
她在接受媒体电话采访时说：“我们相信挖掘区至少将有95%的PCB可以被清除掉。这一数字让我们深以为傲。”
9.And that's the difference between a PCB and, say, something natural like an omega-3, something we want out of the marine food chain.
这与PCB分子是不同的，可以说，就像ω-3脂肪酸一样天然，我们希望海洋食物链里有这些东西。
10.Use the straight-slot screwdriver to pierce between the PCB and upstanding part of the front cover.
