Because the tensileforce in the membrane structure is more complex spatial distribution, therefore, the size of the tensileforce is usually required to be determined by the computer.
因为膜构造内的张拉力呈较为复杂的空间散布，因此，所施加张拉力大小通常需求经过计算机找形来断定。

A ratchet spring provides tensileforce to the ratchet pawl.
棘齿弹簧为所述棘齿爪提供拉力。
