On this foundation, the followingfew problems are resolved. Firstly, we have a kinematic density formula for pairs of needles by using thekinematic density formula for pairs of oriented lines. The geometric probability thatthe random pairs of needles intersect at a point in convex body K is considered.

在此基础上，重点解决了以下几个问题：首先利用R~2上有向直线偶的运动不变密度公式，得到了针偶的运动不变密度公式，考虑了针偶与凸体K相交且针偶的交点属于K的这样一个几何概率问题。

Andwe get two results that kinematic measure of the random pairs of needles intersect inconvex body K and the random pairs of needles intersect at a point in convex body Kby calculation. Thereby, the result of geometric probability problem and its inferencesare gained.

通过计算得出针偶与凸体K相交的运动测度和针偶与凸体K相交且针偶的交点属于凸体K的运动测度这两个结果，从而解决了这一几何概率问题，并得到了相关的一些推论。

The flat knitting is to passes the hand-driven knitting machine move the to eyebrow cam reforming, While knitting Push the top the needle to the needle bed.Make the partial needle of the same line of inside be placed in the different appearance.From but weave a shape of enactment with the pattern.

休止编织是通过对手动横机三角的改造，在编织时将织针推上至针床的最高处，使同一行中的局部针处于不的状态，从而编织出设定的形状和图案。

Then the two-pin fan power plug into the three-pin spare motherboard fan connector on the cathode and anode on the line, the gun is empty of the pin does not matter.

接着把风扇的电源两针插头插到主板空闲的三针风扇接头上的正极和负极上就行了，测速的插针空着也没有关系。

A warp knitting machine for the purpose of carrying out the method comprises at least one thread system which consists of pattern threads laid in intermixed, varying patterns. These pattern threads have underlaps of n, n 1 and n-1 needle spaces and can produce a float and/or a twill.

一个实施该方法的经编机具有一个相应的程序发送器，它在每个工作循环中两次预先确定一个导纱针选择，一个经编织物具有至少一个纱线系统，其由上下不同覆置的花纹线构成，这些花纹具有针距为n，n＋1和n－1的针背垫纱并附加作为浮纱和／或斜纹而移动。

Because of the fact, the bearing capacity of the whole drive cannot be developed well enough. To improve the performances of the load-capacity, transmission efficiency, and reliability of mechanical drive, we originally developed some designs of the double crank ring-plate-type cycloid planetary drive. The new-type drive keeps all the natural advantages, which is of multi-tooth mesh, small mesh angle, and hardened tooth flank of gears. Moreover, The drive does not need the special output unit as the ring-plate-type drive does, so that the rigidity of the output shaft becomes much higher. Since the tumbler bearing is placed outside the cycloidal gear, the size of the bearing is no longer restricted to any extent.

为大幅度提高其承载能力、传动效率和可靠性诸指标，我们创新研究出来的多种结构双曲柄环板式针摆行星传动，其特点是不仅保留着原摆线针轮行星减速器同时啮合齿数多，总法向力与总圆周力间夹角小，摆线轮与针轮齿均为硬齿面等本质上的优点；而且又具有环板式传动省去输出机构且输出轴刚性好，转臂轴承移至行星轮外，从而传递的转矩可以成倍提高的优点。

The needle would stop rolling to maintain the friction effect between the needle and tested tissue when this friction moment come to the driving moment of the friction coupler.

二、在驱动电机和刺激针之间设计一个摩擦耦合器，当刺激针和组织之间的摩擦力矩达到摩擦耦合器的驱动力矩后，刺激针就会停止转动并能保持住对组织的摩擦。
