主要技术指标（Main technical indicators） 

 备注：上下阀件中心距也可表示为H=h×n+h1，其中h为下节中心距，h1为上节中心距，n为下节数量。

（注：除最上节外，都称为下节，最上一节称为上节。）

Remarks: the upper and lower valves’ center distance can be expressed as H=h×n+h1, h stands for the lower segment’s center distance, h1 stands for the upper segment’s center distance, n stands for the quantity of the lower segments.

(Note: The upmost segment is called the upper segment, the rest of the segments are called the lower segment.)
