To assure parts' machining precision and to improve productivity, touch probe is used to inspect cylinder of parts on machining centers, thus coordinate of points on features are acquired from numerical control system by a data collecting program, and cylindricity error is calculated by computer. This method has broken the restriction of probe's macro processor that couldn't work out cylindricity error. Data saved in computer are beyond the limited memory of numerical control system, which improves operation speed.

为了保证零件加工精度和提高生产率，在数控加工中心中采用触发式零件检测测头对被加工件的圆柱面进行在机检测，并利用数据读取程序从数控系统内部提取被检测点坐标信息，在计算机内部完成圆柱度误差的计算，克服了零件检测测头自带宏程序无法对圆柱等被测特征进行误差运算的局限性；并且检测数据存储于计算机内，不再受数控系统内存小及运算速度慢的限制。

PCFK series of pairs of counter-reversible hammer crusher is a new crushing equipment, mainly by knock-on effects to broken materials, broken process in general is this: the material falling into the break in the world, imported high-speed rotation of the hammer impact face was against the entrance of the adjustable crusher tooth wear plate, for the first time broken, broken after the particles basically the same material evenly into the main break, the secondary primary crushing, crushing in the main chamber has been uniformly The material was re-kinetic energy particles from the hammer, high-speed rushed back inside the jagged cavity lining was broken, due to the special lining sawtooth-shaped structure.

PCFK系列可逆双反击锤式破碎机是一种新型破碎设备，主要是靠冲击作用来破碎物料的，破碎过程大体是这样的：落下的物料进入破世界进口后，遇到高速旋转的锤头冲击而被打击到破碎机进口处的可调耐磨齿板上，进行首次破碎，破碎后颗粒基本相同的物料均匀的进入主破碎内，进行二次主破碎，在主破碎腔内已被均匀的物料颗粒从锤头再次获得动能，高速冲向反击腔内部的锯齿形衬板而被破碎，由于衬板特殊的锯齿形结构。

Mobile positioning system or dynamic table so that the laser head is cutting material in the system-driven subcapital high speed, laser head from the light source and cutting heads, light source produces a very short wavelength focused laser beam, laser beam through cutting heads, vertically focused the material being cut on the surface, heating and melting, evaporation is cutting material, resulting in the closure of Lancing, slotted openings formation pads.

移动定位系统妪动工作台或激光头，使得被切割材料在系统驱动头下高速运动，激光头由光源部分和切割头组成，光源部分产生波长很短的聚焦激光束，激光束通过切割头，垂直聚焦在被切割的材料表面上，加热、融化、蒸发被切割材料，形成切缝，闭合的切缝形成焊盘开孔。

Next, regarding question two, because present uses the injection contraceptive the method to maintain this population the stability, moreover already did not have the individual to move away or the situation which poaches, for this reason we transform this populations stability to ask this population every years newborn baby quantity to subtract this year death individual the quantity differential value; Moreover from this population year quantity with this year the end of the years quantity differential value, when tends 0, namely thought that this community individual quantity is stable, thus the question stability problem transforms to ask simple targets optimization problems model building; Carries on using MATLAB to the model obtains, obtains, when did not consider when uncertainty factor influence must inject the medicine female animal quantity is 276 heads, but when had considered after twin and by duplicate injection these two uncertainty factor influence, obtains must inject the medicine female animal quantity is 352 heads, including 110 are by the duplicate injection.

其次，对于问题二由于现在采用注射避孕药的方法来维持该种群的稳定，而且已经没有个体被运走或被偷猎的情况，为此我们把该种群的稳定性转化为求该种群每年的新生幼仔的数量减去该年死亡个体的数量的差值；另外从该种群年头的数量与该年年底的数量的差值，当趋于0时，即认为该群落的个体数量是稳定的，从而把问题的稳定性问题转化为求单目标的最优化问题建立模型；利用MATLAB对模型进行求得，得出当不考虑不确定性因素影响时要注射药物的雌性动物数量为276头，而当考虑了双胞胎和被重复注射这两个不确定性因素影响后，得到要注射药物的雌性动物数量为352头，其中有110头是被重复注射的。

The feed container moving on conveyor belt are feed into an in-feed star wheel, bringing the container below the sealing head in the subsequent indexing part, mean while the rotating head pickup a cap from the cap star wheel which is receiving from delivery chute of cap filling bowl, where the body and the neck of the container are positioned below the rotating head, where the sealing head is performing perfect operation of sealing, rotating head is design to seal container according to pre-set torque

经传送带送入的进料容器被送到一个横向进给的星轮处，然后把容器带到封口头下，与此同时旋转的封口头从盖子星形轮处拾起一个盖子（盖子是经过盖斗的输送斜槽而被送到盖子星轮处的）。容器体和及其颈部被置于旋转的封口头下，而封口头在此处进行完美的封口操作。旋转的封口头是根据预先设置的转矩，进行设计用于对容器进行密封的。

Phase change Ink which is solid at room temperature. The printhead is heated so that

相变油墨。在室温中是固体，打印头被加热，接着油墨变成了液体。

When its head was knocked off, out came a stream of gold, which the Carpenter quickly picked up and said,"Well, I think thou art altogether contradictory and unreasonable; for when I paid you honor, I reaped no benefits: but now that I maltreat you I am loaded with an abundance of riches."

这个肖像的头被打碎的时候，掉下来一块金子，男人迅速的捡起来，自言自语道：&我觉得吧，你就是有点不可理喻，我天天供奉你的时候，什么也得不到，我现在虐待你，你却让我变富有了。&

When its head was knocked off, out came a stream of gold, which the Carpenter quickly picked up and said,"Well, I think thou art altogether contradictory and unreasonable; for when I paid you honor, I reaped no benefits: but now that I maltreat you I am loaded with an abundance of riches."

神像的头被摔断下来，一道金泉一涌而出，木匠连忙拾起神像，并说：「我想你简直是无理得使我无所适从。尊敬你，供奉你，却得不到好处；对你不好，倒使我发了横财。」这个故事带出的启示就是：有些人敬酒不吃吃罚酒，对这样的人只有采取强硬的对策。
