During transmission, they employ special collision-avoidance and arrival-acknowledgment techniques that are not required in wired Ethernet LANs.
在传输过程中，他们采用有线以太网不需要的、特殊的避免碰撞和到达应答技术。
Just to make sure that the source of the interfering transmission also detects a collision, upon detecting a collision, a station sends a "jam" signal for 32 bit times.
为了确保发送干涉信息的源头也能知晓发生了数据碰撞，发射站在检测到碰撞后，要发一个是32比特的倍数的拥塞信号。
The third case is due to the deformation of the transmission shaft caused by the imbalance, the general situation in the chassis collision over the car.
第三种情况是因为传动轴变形不平衡引起，一般这种情况出现在底盘碰撞过的车比较多。
