导向体

On the basis of studying the mechanism of the self-excitation vibration and the helix lobes of the cylinder in the well logging tool during deep-hole boring, th e influence of the length of the guide pads on the torsion deformation and stabi lity of the boring cutter is analyzed.

在论述深孔镗削加工过程中自激振动和螺旋沟产生的机理后，分析了石油测井仪器筒体深孔镗削加工中导向块长度对镗刀扭转变形和稳定度的影响。

One year later, Slit was confirmed as the ligand of Robo and the Slit-Robo signaling is know involved in the repulsive effect of the commission axons crossing the mid-line, and also involved in the repulsive effect of the guidance of neuronal migration and leukocyte migration as well.

而对 Slit 功能展开的研究起于1998年，先是发现其受体 Robo突变型果蝇的中线处交叉神经元的导向发生缺陷。1999年的一系列遗传和生化的研究又发现，分泌性因子 Slit 正是 Robo 的配体， Slit － Robo 信号起到了排斥一些轴突，使之无法穿过中线的作用。

Rules and a case study are also presented to exemplify the result of applying our methodology on both OOSE and imperative software engineering.

分别针对物件导向软体工程以及传统软体工程，我们将提出规则以及实力探讨来作为例证以了解实行我们所提出方法论所得到的结果。

The percentage of linear and so quick Figure 1 Three common control valve sleeve sleeve diagram Interchangeability of parts from Ball Valves the valve to see some adjusting mechanism trim can be easily replaced and maintained, for example, the sleeve valve sleeve can be easily replaced to achieve different flow characteristics; top and bottom-oriented trim can be easily turn the spool and the valve seat to achieve positive and anti-body to replace the valve body to achieve the air to open the way to replace gas off; valve isolation valve can be easily dismantled for the seat replacement and cleaning.

快开 线性等百分比图1 三种常用套筒控制阀的套筒示意图从阀内件的互换性看，一些调节机构的阀内件可方便地更换和维护，例如，套筒阀可方便地更换套筒实现不同流量特性；顶底导向的阀内件可方便地翻转阀芯和阀座来实现正体阀与反体阀的更换，从而实现气开和气关方式的更换；阀体分离阀可方便地拆卸，用于阀座更换和清洗。
