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型直流电表是磁电系张丝承指针指示可携式电表,仪表具有良颠震性能和较高灵敏度及使用寿命.

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.

考虑到檩下替存在,根据承点处檩和替转角相等原则确承点位置,从而计算檩最大内力。

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.

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