Silica capillary is chosen to be the suitable tube for fabrication hollow - core fiber by comparing series of material . ultraviolet reflectivity of metallic aluminum is the highest versus other metallic material , so metallic aluminum is the optimum material for fabrication hollow - core fiber 通过比较选择了用来制备空芯光纤合适的基管材料即石英基管；相对于其他的金属材料而言，金属铝的紫外反射率最高，因此金属铝最适合用做制备空芯光纤的金属膜层材料。
The target determines the precision , reliability , stability and tcr of the resistor . on the other hand , the coatings play an important role in improving the heat - resistance and moisture - resistance of the resistor . however , nowadays the study in this field is some deficient in our country 此外，金属膜电阻器的耐热、耐湿、耐腐蚀性能还直接与金属膜电阻器表面的保护涂料的性能密切相关，而目前国产的涂料在耐高温、耐高湿方面还达不到国家军标的要求。
In order to solve the above - mentioned problems , the present invention provides a method for plating a polymer material with a metal film , which can form the film on the surface of polymer materials , which are difficult to plate by the prior wet plating method , at a relatively low cost in comparison to the dry plating method and exhibits a uniform thickness and a good adhesion of the metal film and further , shows a good reproducibility 为了解决上述问题，本发明提供了一种给聚合物材料上镀金属膜的方法，用该方法可以在聚合物材料表面形成膜层，这是原来的工艺难于做到的，而且比干镀成本低，镀层厚度均匀，金属膜的粘附性好，最后，还显示出好的重现性。
The dry temperature of the metal membrane rangs from 50 c to 60 c , dry time of metal membrane is 10 minutes ; the rate of heat - up is 5 v / 30mins ; the pore size and permeability of metal membrane reduce with the sintered temperature of metal membrane rising . when sintered temperature is over 1000 , the influence of sintered temperature to pore size is small 在刷涂工艺条件下，用hdh钛粉制备的多孔金属膜的干燥温度为50 ? 60 ，干燥时间为10分钟；升温以5v / 30min进行；多孔金属膜的孔径随着烧结温度的升高而降低，当烧结温度在1000以上时烧结温度对孔径的影响较小。
