实验结果表明，贫铀中的碳含量对射流性能起着非常重要的作用，随着碳含量的增加，静破甲威力下降十分显著。

The results of these tests indicate that impurity carbon have an important influence on the behavior of depleted uranium shaped charge jet .

晶粒度越细小，越有利于增加有效连续射流长度，推迟了射流断裂时间，提高了静破甲威力水平。

The more fine grain size becomes , the more long the effective continuous jet length would become so that break-up time of jet would delay and power of static armor-piercing power would increase .
