Cracked tungsten tubes prepared by chemical vapor deposition were investigated by ring machine cutting method and X? Ray stress analysis system.
采用切环测量法及X射线应力分析方法对化学气相沉积制备的开裂钨管进行测量与分析。
The formation of these WO3 tubes is attributed to the lateral coalescence of tungsten oxide nanowires.
这种氧化钨管是由多根平行生长的氧化钨纳米线横向联合而成。
The corrosion protection practice showed that the tubes with protective coating of nano titanium polymer and alloy tubes with tungsten-plating performed well in the corrosive environment.
实践表明，“钛纳米聚合物防腐蚀涂层油管”和“镀钨合金防腐蚀油管”在上述环境使用较为适合；
