求翻译：因此,安全可靠的防护装置应主要考虑在随机的碰撞事件中能以相对固定的破坏形式来耗散碰撞能量，有效控制碰撞力和减速度以及防止后车发生钻入碰撞。是什么意思？

Therefore, safe and reliable protective equipment should be primarily considered a relatively fixed form of the destruction of the random collision to dissipate collision energy, effective control of the collision force and deceleration, and the prevention of the following vehicle to penetrate into

Therefore, the security guard should be reliable, mainly taken into account in the case of random collision events in relatively fixed in the form of energy dissipation collision collision force, effective control and speed as well as to prevent the drill after a car collision.

Therefore, the safe reliable protective equipment should mainly consider can come the diffusion collision energy in the stochastic collision event by the relatively fixed destruction form, after the active control impact force and the retarded velocity as well as prevented the vehicle occurs drills

Therefore, safe and reliable protection of installations should be considered mainly in random collision in the event of collision energy dissipation as a relatively fixed damage, collision force and speed reduction of effective control and to prevent drilling in the car after the collision.
