求翻译：（2）式表述为：吸能器吸能量E1与碰撞总能量E2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: energy absorber absorption energy e1 and collision energy e2 ratio of about 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: The suction to be 1 and the collision energy E E total energy than the 2 to 3 - 4 % left and right, you can catch up to collision and tail in the crash of all the basic to avoid injury or death, and named LC automobile collision energy-absorbing safety injury factor

(2) expressed as: energy-absorbing collision energy absorption E1 and E2 of the total energy than when you reach about 3-4%, you can make all occupants in a collision and rear crash to avoid casualties, and known as the LC zero injury safety vehicle crash energy absorption coefficient

(2) type the indication is: The power absorber attracts energy E1 and ratio of the collision total energy E2 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
