It 'mainly concludes these characteristic parameters, such as visual, dryness, ion contamination, welding flux residual, surface insulation resistance and electric migration et al.
这些参数主要包括：外观、干燥度、离子污染、助焊剂残留、表面绝缘电阻和电迁移等。

The test results show that the electric resistance of Al nano-beams with tensile stress is instability.
电学测试结果表明：张应力下金属纳米梁的电阻值不稳定。

I think the fault is probably electric (al) current.
