根据实际生产需要，运用刀杆开槽、螺母弹夹、圆销定位等原理设计出弹夹式微型机夹硬质合金精镗刀，很好的解决了小深孔零件的精密镗削加工。

For example, the roll elastic deformation breaks the statically determinate condition of roll system in duo mill, and this is the main reason of bearing longevity shortening and burning accident; in aluminium foil four-high mill roll system with a 1 mm gap, the ideal position kept by a 3 mm offset is out of effect, some phenomenon such as chock horizontal vibration, gyroscopic effect and micro dimensional dynamic cross happen in fact rolling process, abnormal super and partial load resulted by these is the main reason of the end thrust bearing accident; the thermal deformation of mill roll system accompanying the temperature raising not only changes the roller track age of rolling bearing, but also results a micro dimensional slow dynamic inverse cross that counteracts the gyroscopic effect in a degree.

如二辊高刚度轧机轧辊的弹性弯曲微尺度行为，破坏了辊系机构杆系的静定条件，成为轧机轴承短寿烧损的主要根源；铝箔四辊轧机只具有1mm的有隙辊系，凭借设置3mm偏移距和轧制力平衡产生的水平力以保持轧辊理想定位失去效用，却发生轴承座水平振动现象、陀螺效应和动态交叉微尺度行为，成为止推滚动轴承异常超偏载导致短寿烧损的主要根源；轧机辊系的伴随升温产生的热变形，不仅改变了滚动轴承滚道轮廓，还引起运动副内慢变动态反交叉微尺度行为，抵消陀螺效应的部分动态交叉角度。

In addition,the dwarfing character of'88〓185'were monosomicanalysised also.

Locator valve amplifier wear off by the loose dirt, gas consumption in particular will increase the output generated turbulence;② nozzle locator in the amplifier is not parallel to the baffle, baffle cover any of nozzle;③ Output tube, line leak;④ executive body rigidity is too small;⑤ stem movement friction large parts of a block in contact with the phenomenon.

定位器中放大器的球阀受脏物磨损关不严，耗气量特别增大时会产生输出震荡；②定位器中放大器的喷咀挡板不平行，挡板盖不住喷咀；③输出管、线漏气；④执行机构刚性太小；⑤阀杆运动中摩擦阻力大，与相接触部位有阻滞现象。

Most of the developing X-Y tables applied Ball screw-driven table system or piezo-ceramic linear motor by taking the advantages of carrying heavy loads. However, their cost are very high in contrast to the proposed architecture. In some particular application fields. Carrying heavy loads is not the main requirement for the X-Y table, such as organic cell inspection, optical fiber alignment, nano-material research, ect. Taking this idea as a premise, if we could able to create a precise positioning X-Y table with very low cost, we will be able to achieve the extremely high commercial value and highly competitive ability.

X-Y精密定位平台的开发，不外乎线性马达或压电陶瓷马达搭配导螺杆或其它机构所组成，其优点是可以承载较重之待测物体，缺点是重量大且价格昂贵，在许多应用上并不要求测试平台拥有太大的荷重能力，如生物医学诊断及检测，生物晶片开发及检测，光纤校准，奈米材料研发，奈米量测及精密全平面扫描等等，如果以此为前提，能以极低之成本创造出高精密定位之X-Y平台，将会有极高之商业价值及极大之竞争力。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
