金属膜保存期限是个头痛的问题，比如银金属膜，后期保存和使用对膜层的变化快慢起到很大的作用，我想问诸位大仙的是：铜金属膜在什么样的厚度什么样的保存条件下保存时间最长，在温度25度，相对湿度50%的情况下，能够存放多长时间不变质、氧化？ ...

The cryopumps are external to the system, they are extremely conductance restricted. The speed rate of a 1 inch cryopumps is about 15,000 l/s. But they must be isolated by elbows gate valves, etc. (They also need to be thermally isolated in many cases by elbows, baffles, etc.) Due to the conductance ...

如果膜料在存放过程中受潮,那么用它镀制的膜层会出现什么样的结果?会不会出现花斑???

对不起，刚才按错键了！
