大应变鞘形引伸计的设计

介绍了一种电容式鞘形大应变引伸计，被测应变可达到９０％，且由于测量电极可完全滑出鞘体，故该引伸计两刀口间之位移无上限位移量的限制。推导了平均输出电平的表达式，文中给出了测量电路和实验结果。

Design of Large Strain Sheath Extensometer

This paper gives a large strain sheath extensometer by capacitance mode Seeing that the movable element can more away from shed blade displacement of extensonmeter is without limit. The relation between the outgoing level and the strain was established theoretically and checked in the test.
