通过模拟新型反应装甲抗100滑钢弹的抗弹性能试验，计算其局部防护系数达到3.514，证明了所设计的新型反应装甲能够实现小法线角防御初速为1700m/s的大口径穿甲弹，能够达到战术技术指标要求，满足坦克炮塔对大口径穿甲弹的防御。

I request only the barest needs for myself and my people.

我只为我自己和人民最微薄的要求请愿。

It is better to choose small diameter catheter as far as possible if it does not request super-speed drop. It's best to choose basilic vein at first, especially the right side, with the puncture point going over the elbow joint; and the next best choice is the jugular external vein on the right side as well. Thereby, it is better to choose cautiously the PICC tube operation and make detailed valuation before operation.
