A washer has a body having an axis and provided with a first bearing face surface located at one axial side and adapted to cooperate with a nut, a second bearing face surface located at an opposite axial side and adapted to cooperate with an object, at least one third turning resistant surface adapted to cooperate with a thread of the bolt, the body having at least one resistive point arranged so that when the nut is turned and turns the bolt the body of the washer stops the bolt from turning and thereby the nut creates a pull on the bolt which elongates the bolt in an axial direction and applies to the body of the washer an axial force which overcomes the at least one resistive point so that a portion of the body of the washer is allowed to be pulled axially when the bolt elongates.

一种放在螺帽与物体之间的垫圈，螺帽与螺栓螺纹连接，螺栓插入在包括两个装配的部件的物体内，垫圈具有主体，和设有第一支承面表面，位于一个轴向侧面和与螺帽配合，第二支承面表面，位于相对的轴向侧面和与物体配合，以及至少一个第三转动阻力表面，与螺栓的螺纹配合，从而使螺帽以给定的扭矩在一个方向转动同时垫圈的主体沿相对方向接收给定的力时，仅有螺帽转动，以紧固或松开螺栓，而垫圈的主体和螺栓保持静止。

The amplified fragment was inserted into pRSET-A to generate the first double repeat of the precursor gene. By utilizing a pair of isocaudamer BamH I and Bgl II sites, and another downstream Hind III site of plasmid pRSET-A, following a series of simple double digestions and ligation of the resulted products, a series of repeat (3, 4 and 6) precursor peptide fragment genes were derived.

本实验设计一对两侧含编码疏水性氨基酸密码子的引物，经过扩增前导序列10~34aa基因序列，并重新克隆入质粒pRSET-A构建串联二聚体后，再利用质粒pRSET-A的BamH I / Bgl II同尾酶克隆位点，经一系列简单的酶切和连接，快速构建这一前导肽中不含组氨酸标签序列的串联多聚体基因，并成功表达其六聚体重组蛋白。

Further experiments such as Far-western and immunoprecipitation confirmed this interaction in vitro and in vivo.
