rangeability

1.The sediment types and their superimposed features in log data can conversely verify the rangeability of relative accommodation space.

通过录井岩性资料中沉积物类型及其叠加特征以反推相对容空化幅度。

2.Where rangeability is not a concern, linear trim may be used if the valve pressure drop is greater than one third of the inlet pressure (in absolute units).

在调比无关地方，如果阀门压降大于阀前压力1/3（绝压），使用线性阀内件。
