如果需要使用的导线长度超过25毫米,或者使用裸导线会造成焊盘与零件脚之间短路,这些情况下必须使用有绝缘皮的导线。
How to translate this sentence?Wire is insulated if greater than 25 mm in length or is liable to short between lands or component leads.
注意,顶部的电极接保护,所以只有流经绝缘体表面的电流才为皮安计所测量。
Note the top electrode is guarded, so that only current flowing across the insulator is measured by the picoammeter.
石棉纤维耐热、防火、不与化学品发生反应,曾被广泛用于建筑业和绝缘材料。人们后来发现石棉会引发石棉沈滞病、肺癌、间皮癌和其他癌症。
Asbestos fibres, resistant to heat, fire and chemicals, were widely used in construction and insulation before being linked to asbestosis, lung cancer, mesothelioma and other cancers.
