PURPOSE To compare fragmentationeffect on stone by wide focus Shockwave with that by sharp focus one.
目的比较窄焦斑与宽焦斑冲击波的碎石效果。

For effectively measuring the nucleon strange asymmetry, we investigate the light quark fragmentationeffect that may affect the measurement of the strange asymmetry.
为了探讨测量这种奇异分布不对称性的有效方法，考察了轻味夸克碎裂效应对测量奇异分布不对称性的影响。
