The invention relates to a nut (10) comprising an outer body (16) with an axial passage (22), an inner body which can be movably placed in the passage along an axial direction and which is divided along said axial direction into at least two jaws (18, 20), each jaw bearing an inner thread segment (24) on its radial inner surface, first guiding means (26) located on the outer body, as well as second guiding means (30) located on the jaws and co-operating with the first guiding means so that the jaws are radially displaced towards the exterior when the outer body is displaced in the unscrewing direction relatively to the inner body et radially displaced towards the inside when the outer body is displaced in the screwing direction relatively to the inner body.

本发明涉及一种螺母(10)，它包括：一个带轴向通孔(22)的外体(16)；一个内体，位于通孔(22)中，可沿轴向移动，并且沿所述的轴向方向至少分成两个滑块(18、20)，它们各自在其径向的内表面上具有内螺纹部分(24)。在外体上有第一导向装置(26)，同样滑块上有第二导向装置(30)，第二导向装置与第一导向装置共同起作用，所以，当外体相对于内体沿旋松方向作相对滑移时，滑块径向地向外滑移，并且，如果外体相对于内体沿拧紧的方向滑移，则滑块径向地向内滑移。

The key to vision-based navigation is rapid detection and recognition of obstacles. Stereo vision is rapid, accurate and easy to conceal, as it is a passive measurement, which does not emit light and radiation.

Results (1)ATP could inhibit the proliferation of U937 cells with inhibition rate over 43% after 48hour ATP treatment;(2)ATP treated U937 cells numbers increased obviously in G1 phase,and apoptosis peak appeared before G1 phase,apoptotic cell number was 3.4% for 24hour,and was 22.7% for 48hour of ATP treated U937 cells;(3) Nuclear chromatin condensed into sperical masses bound cytoplasma membrane formed apoptotic bodies which is shed from membrane surface into intercellular medium;(4) Apoptotic bodies were nigrosine staining negtive.

结果 (1)ATP对U937细胞的增殖有按摩明显的阻抑作用，加药48h后增殖的抑制率可达43%以上；(2)ATP处理的U937细胞周期发生改变，G1期细胞数按摩明显增多，ATP作用24h时G1期前出现亚二倍体峰——凋亡峰，凋亡细胞数为3.4%，作用48h时凋亡细胞数增多为22.7%；(3)ATP处理的U937细胞首先在核内染色质浓缩成半月形贴近核膜，逐渐向核膜外移动，进入胞浆内再移向质膜内外面，紧贴质膜外面再逐步脱离细胞体，进入细胞基质中，成为游离的凋亡小体。

Experimental results show that the different substituted location and different substituted group on benzene cycle would result in the diversity of reduction properties of substituted aryl nitrobenzene. Substituted nitrobenzenes with withdrawing group will be reduced at more positive potential, while those with repelling group will be reduced at more negative potential. In addition, the reduction potential of nitro group of o-nitrobenzene shifts more negative due to the effect of space resistance.

结果表明，芳族硝基化合物在苯环上的取代基位置不同以及在相同位置上取代基的种类不同均可使各芳族硝基化合物的电还原性能发生较大差异：吸电子取代基在电还原过程中电位较正，推电子取代基的电还原电位较负：邻位取代基在反应过程中由于空间位阻效应，苯环上的硝基在电还原时电位往负方向移动。
