求翻译：（2）式表述为：吸能器吸能量E与碰撞总能量F之比达到3-4%左右时，就可使碰撞和追尾车祸中的所有乘员基本避免伤亡，并定名为LC汽车碰撞零伤亡安全吸能系数是什么意思？

(2) is expressed as the ratio of the energy e and f of the total collision energy: energy absorber absorption of 3-4%, you can make all the collisions and rear-end car accident crew basically to avoid casualties, and named lc car collision zero the casualties Security energy absorption coefficient

(2) expression is: will the suction and the collision energy E F total energy of more than 3 - 4 % or so, it can be to collision up in a traffic accident and all occupants of the base to avoid injury or death, and named LC automobile collision energy-absorbing safety injury factor

(2) expressed as: energy e and total collision energy absorption of energy absorption ratio of f when you reach about 3-4%, you can make all occupants in a collision and rear crash avoiding casualties, and known as the LC zero injury safety vehicle crash energy absorption coefficient

(2) type the indication is: The power absorber attracts energy E and ratio of the collision total energy F achieved when about 3-4%, may cause all crew members who collides and follows in the traffic accident to avoid the casualties basically, and chooses a name is the LC automobile collision zero c
