Generally, drawing machine has four motors, two stepping motors control movement of pen and paper, and the other two direct current electric motors control the spools of giving paper and spooling paper.

服装绘图机主要包括四个电机：两个步进电机分别控制笔和纸的运动，两个直流电机分别控制给纸和退纸的卷轴。

Heretofore, the mother, while loving her child with the intensity of a soul affection, had schooled herself to hope for little other return than the waywardness of an April breeze; which spends its time in airy sport, and has its gusts of inexplicable passion, and is petulant in its best of moods, and chills oftener than caresses you, when you take it to your bosom; in requital of which misdemeanours, it will sometimes, of its own vague purpose, kiss your cheek with a kind of doubtful tenderness, and play gently with your hair, and then be gone about its other idle business, leaving a dreamy pleasure at your heart.

孔。此前，做母亲的虽以极其专一的钟爱爱著她的孩子，却总在告诫自己，且莫指望得到比任性的四月的微风更多的回报——那微风以飘渺的运动来消磨时光，具有一种难以名状的突发的激情，会在心情最好时勃然大怒，当你放它吹进怀中时，经常是给你寒气而不是爱抚；为了补偿这种过失，它有时会出於模糊的目的，以一种值得怀疑的温柔，亲吻你的面颊，轻柔地抚弄你的头发，然后便跑到一边去作别的无所事事的举动，只在你的心中留下一种梦幻

For instance when the evicted tenants question, then at its first inception, bulked largely in people's mind though, it goes without saying, not contributing a copper or pinning his faith absolutely to its dictums, some of which wouldn't exactly hold water, he at the outset in principle at all events was in thorough sympathy with peasant possession as voicing the trend of modern opinion (a partiality, however, which, realising his mistake, he was subsequently partially cured of) and even was twitted with going a step farther than Michael Davitt in the striking views he at one time inculcated as a backtothelander, which was one reason he strongly resented the innuendo put upon him in so barefaced a fashion by our friend at the gathering of the clans in Barney Kiernan's so that he, though often considerably misunderstood and the least pugnacious of mortals, be it repeated, departed from his customary habit to give him one in the gizzard though, so far as politics themselves were concerned, he was only too conscious of the casualties invariably resulting from propaganda and displays of mutual animosity and the misery and suffering it entailed as a foregone conclusion on fine young fellows, chiefly, destruction of the fittest, in a word.

比方说，佃户被迫退租的问题当时刚刚冒头，引起民众极大的关注。不用说，他本人连分文也不曾捐赠给这一运动，而且其纲领也并非完全没有漏洞。他不能把信念绝对地寄托在上面。他认为佃户拥有耕作权符合当代舆论的趋势，起初作为一种主义他全面地赞成；及至发现弄错了，就部分地纠正了自己的偏见。由于他竟然比到处游说耕者应有其田的迈克尔。达维特的过激意见甚至还进了一步，从而遭到嘲笑。正因为如此，当这帮人聚在巴尼。基尔南酒馆露骨地讽刺他时，他才那么强烈地感到愤慨。尽管他经常遭到严重的误解，再重复一遍，他仍不失为最不喜欢吵架的人。然而他却一反平素的习惯，朝着对方的肚子给了一拳。就政治而言，他对双方相互充满敌意的宣传与招摇所必然导致的伤害事件及其不可避免的结果——主要是给优秀青年带来不幸与苦恼——一句话，对适者灭亡的原则理解得再透彻不过

The introductive robot arm of this text can output two lines pulses by the PLC, driving the horizontal stalk, and the perpendicular stalk to drive the electrical engineering actuator respectively, to control the robot arm precision of the horizontal stalk and perpendicular stalk at the fixed position, tiny move switch input the position signal to the PLC.The direct current motor drags along to begin the claw and bedrocks to revolve, the position signal from revolve the code dish and near to the switch feedback to host of PLC;The electromagnetism valve control the machine hand open and close, thus carry out the function of the machine hand precision work.

本文介绍的机械手是由PLC输出两路脉冲，分别驱动横轴、竖轴步进电机驱动器，控制机械手横轴和竖轴的精确定位，微动开关将位置信号传给PLC主机；直流电机拖动手爪和底盘旋转，位置信号由旋转码盘和接近开关反馈给PLC主机；电磁阀控制气开阀的开关来控制机械手手爪的张合，从而实现机械手精确运动的功能。
