Model C31 Meters are multirange instruments and a plug-in type switch is used for range change-over,so for the sake of easy operation.

C31型直流电是磁电系张丝支承指针指示可携式电,具有良好的防颠震性能和较高的灵敏度及使用寿命.

The position of bearing point is got according to the equal angle of rotation between purlin and Queti,thus its maximum internal force can be obtained.

考虑到檩下替的存在,根据支承点处檩和替的转角相等的原则确定出支承点的,而计算出檩的最大内力。

Further adding to occupant safety, frontal impacts are absorbed by crumple zones directed into Y-shaped chassis members and the main understructure – the strongest part of the chassis.

正面的撞击由溃缩区吸收并传递到Y型底盘部件和主要支承结构-地盘最坚实处，而进一步保护乘客安全。
