Firstly, the principles and characteristics about column type vector hydrophone are studied in this paper.

首先，本文从理论上对柱形矢量水听器的工作原理及其特性进行了分析。

Fixed shell type vector hydrophone belong to mechanical type acoustic vector hydrophone, however moving shell type vector hydrophone belong to inertial type acoustic vector hydrophone.

不动外壳型矢量水听器属力学型矢量水听器，而同振型则属惯性型矢量水听器。

The type of vector depends on the type of value promoted.

向量的类型取决于所提升的值的类型。

For example, even though a Nuke would cause ninety billion dollars in destruction the probability of this type of attack is so low that it creates a vector value below the benchmark needed to consider it a daily threat.
