The static model of torsion joint is based on that of bending joint. The effects of structure parameters inside air pressure, initial angle, rube average radius, rube shell thickness on the turning angle are analyzed and the following conclusions are drawn: the relationship between the angle of torsion joint and the inside air pressure is basically linear, the angle of torsion joint increases with the initial angle and rube average radius, the angle of torsion joint decreases while the rube shell thickness increases. The kinetic equation is built for torsion joint. Simulating experiment implies that the time of inflating and deflating process is extremely shorter than that of kinetic process. So the pneumatic process can be ignored in actual system design and control. The factors that affect the dynamic features of torsion joint, such as shell thickness of rubber tube, average radius, initial angle, connector's outlet area, moment of inertia and viscous damping coefficient, are analyzed and the following conclusions are drawn: the change of rube shell thickness has no effects on the dynamic process of FPA inside air pressure while greatly affects the turning angle of torsion joint; when the rube shell thickness is small, the torsion joint has a bigger turning angle, no overshoot and long risetime, when the shell thickness is big, the turning angle of torsion joint is small, but has high response speed, overshoot and low shock; when the rube average radius increases, the turning angle of torsion joint increases and the overshoot increases too; when the initial angle of torsion joint is big, the turning joint is big, the overshoot is small and shock is low, but the risetime is big; the connector's outlet area affects the dynamic process of FPA inside air pressure greatly, but has no effects on the dynamic process of turning angle; moment of inertia and viscous damping coefficient have no effects on the dynamic process of FPA inside air pressure, but affect the dynamic process of turning angle greatly.
在弯曲关节模型推导的基础上,建立扭转关节的静态模型,并分析了扭转关节内腔压力,初始转角,橡胶管平均半径,橡胶管壁厚等参数对关节转角的影响,得出扭转关节的转动角度与充入FPA内腔的压缩气体压力之间基本呈线性关系,扭转关节的转角随初始角度和橡胶管平均半径的增大而增大,扭转关节的转角随橡胶管壁厚的增大而减小的结论;建立了扭转关节的动力学方程,仿真实验表明FPA的充放气过程与扭转关节的动力学过程相比时间极短,在实际系统设计和控制过程中可以忽略不计;分析讨论橡胶管壁厚,平均半径,初始角度,气体节流口面积,转动惯量,粘性阻尼系数等因素对扭转关节动态特性的影响,得出橡胶管初始壁厚的变化对扭转关节FPA内腔压力的动态响应几乎没有影响而对关节转角的响应曲线影响比较明显,壁厚较小时,关节可以得到较大的转角,并且转角的响应曲线没有超调,但上升时间长,壁厚较大时,关节转角变小,响应加快,但是有超调和轻微振荡现象,橡胶管平均半径越大,得到的关节转角越大,但是转角响应的超调量也随之增大,FPA的初始角度越大,关节的转角越大,并且超调量减小,振荡减弱,但是上升时间增大,管接头出口面积的大小对关节FPA内腔压力的建立过程影响较大,但对关节转角的动态响应几乎没有影响,转动惯量和粘性阻尼系数对FPA内腔压力的动态过程几乎没有影响而对扭转关节转角有较大影响等结论。

The analyses of social and economic development indicate that, up to 1998, the total population in Yijinholo County is 143, 949 persons, the population density is 24 persons per square kilometer, large population number results in land exploitation for food and overgrazing in rangeland. The change in temporal and spatial pattern of landuse from 1977 to 1998 demonstrates that mobile sand dunes was replaced by rangeland and woodland and partial shrubland in the middle of study area changed into rangeland and farmland from 1977 to 1987, while mobile sand dunes and rangeland transformed into shrubland and farmland in a small parts from 1987 to 1998, the above-mentioned change is proved by the change of fractal dimension index and fragmentation index at landscape and its element levels.
对近50年来伊旗社会经济发展的分析结果表明,虽然人口增长率基本上呈下降趋势,但由于人口基数较大,截至1998年底,伊金霍洛旗的人口总数达143949人,人口密度为24人/平方公里,较高的人口密度带来了更多的生存需求,使得大量的草牧场被开垦,而剩余的则严重超载。1977-1998年间伊土地利用结构总体格局变化的分析结果表明,1977-1987时段内主要是流动沙地为草牧场和乔木林地所取代,伴随着中部的部分灌木林地转换为草牧场和农地:而1987-1998时段内主要是草牧场和流沙地为灌木林地和农地特别是灌木林地所取代,而景观及各景观要素的分维度指数和破碎度指数的变化也充分证实了这一结论,虽然在前10年(1977-1987年)中大面积的灌木林被砍伐,但土地利用格局的整体变化间接地反映出该时段内荒漠化的状况正在发生逆转。

NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.
通过研究,我们提出了初步的NodD操纵子激活模型:第一,四聚体是NodD蛋白的功能单位,它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子;第二,小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体,在我们的模型中,NodD四聚体缩小其V形主体的弯折角,进而缩短其DNA结合功能域的间距;第三,小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用,NodD的构象改变由蛋白质经其双铆钉位点传递给DNA;第四,只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物;第五,不排除NodD与RNA聚合酶可能有直接的相互接触位点,不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物,但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。
