initial collision meaning in Chinese
初始碰撞
首次碰撞
Examples
- Weaver says it may have been an initial collision with an asteroid , or perhaps the comet ' s rapid rotation caused it to unravel
维沃说这或许是跟小行星相撞引起的，抑或是慧星的高速旋转导致的分裂。 - The knowledge of these initial collision is crucial for any theoretical treat - ment of a possible parton - hadron phase transition , the detection of which being the ultimate aim of all the efforts of co1liding heavy ions at very high energies . the parton model allows to calculate inclusive cross sections as a convolution of any elementary cross section with parton distribution functions , assuming that factorization works . the disadvantage is that tlle first interaction is coilsidered quite differently from the subsequent ones in case of multiple scattering
其它的弦模型在计算几率时，忽略了入射能量在pomeron之间的分配，破坏了能量守恒，而且把pomeron作为全同粒子处理，即pomeron之间是不可区分的；然而在处理粒子产生时，这些模型虽然考虑了能量守恒，但是第一个pomeron的粒子产生与其它的pomeron很不一样? ? pomeron在粒子产生时不是全同的。
