An upward stroke from the tip to the heel of the bow . Huffman Coding Based on a Top-Down Approach

一种从顶部到腰后部的 向 上 手法。一种基于自顶向下的 哈夫曼编码方法

The current peak of upward lightning stroke ( 8 ~ 10kA ) is less than all other strokes .

上行自然闪电 回击电流峰值（8~10kA）小于其他类型的回击。

This critical piston position of crank angle should correspond to the time when the in-cylinder tumble has to be distorted and destroyed by the upward moving piston during the late stage of the compression stroke .

活塞临界位置与在压缩 冲程后期活塞 上行、缸内滚流开始畸变、破碎的活塞位置相当。
