在运动

In this system the motion controlling centers upon regulating the speed of wire feeding and movement of lead screw in each direction.Four motors separately drive the wire-feeding tape roll and the lead screw move respectively following their directions of X, Y, Z axis. If all the motors are controlled by 89C51 directly,it will rise great difficulty for software and hardware implementation. So the suggested solution is to combine the microcomputer with stepper motor driver and control of their motion.

在本系统中运动控制的关键即送丝与各丝杠移动的调节，由四个电机分别驱动X，Y，Z轴方向的丝杠行走以及送丝操作，运动控制部分如果用89C51直接驱动各电机则在软件和硬件实现上都比较困难的，所以选用单片机与步进电机驱动器结合起来控制它们的运动。

Linear motor is a kind of equipment for converting electrical energy into linear movement use. In most occasions where need converting rotary movement into linear movement, linear motor shows its superiority. It makes many in-between transferring machine unnecessary. Therefore, the whole system runs more steadily. In addition, thanks to the reducing of the in-between machine, the friction wastage of the whole system is reduced and the efficiency of the whole system is improved.

The analysis of polymer structure indicates that the non-crystalline phase is the majority of the agglomerate structure and the crystalline phase is the minority, the highest crystal value only reaches the level of 0.1646;There is a definite interactionadditives and PVA, which not only reduces the crystal value of ASPE to make amorphous areas enlarge but also improve the ability of segmental motion by destroying the well-regulated and orderly character of polymer chain, meanwhile restricts the mobility of potassium cation and enhances the anionic transference number of hydroxide ions, all these improve the ionic conductivity;The ionic conductivity occurs essentially within the amorphous phase of the ASPE;The structure of ASPE doesnt change in the range of our test temperature, this means, the temperature only takes effect on degradation of complex in certain compositions, ionic mobility and segmental motions of the polymer chain.

聚合物结构分析表明：碱性固体聚合物电解质中凝聚态结构以非晶态为主，仅有少量的晶态，结晶度最大为0.1646；添加的各组分与PVA之间都有一定的相互作用，这种作用不仅破坏了聚合物链段的规整性，能够降低聚合物的结晶度，增大无定形区域，提高链段运动的能力，同时这种作用限制K~+离子的运动，提高OH~-的迁移率，从而提高离子电导率；碱性聚合物电解质的离子传导主要发生在无定形区；在本实验测试离子电导率温度范围内，聚合物内部的结构不会发生变化，即温度只会影响电解质内部络合物解离程度和载流子迁移以及聚合物链段运动的情况。

Lacunar infarction in patients with hypertension is also common cerebrovascular disease, clinical manifestations of light, many people without clinical symptoms, and in nuclear magnetic resonance, CT examination or autopsy, was found when more specific clinical symptoms are: a simple movement obstacles, mild hemiplegia, aphasia or without sensory disturbance; pure sensory disturbance, migraine paresthesia or loss of body; dysphonia - clumsy hand syndrome, manifested as paresis and paralysis of tongue, speaking clearly, swallowing difficulties, fine motor hand and foot less flexible; ataxia and hemiparesis, inability to break limbs and lower limbs than upper limbs, uncoordinated movements, these symptoms often disappear in two weeks.

腔隙性脑梗塞也是高血压患者中常见的脑血管病，临床表现较轻，很多人无临床症状，而在核磁共振，CT检查或尸体解剖时才被发现，较为特殊的临床症状有：单纯运动障碍、轻度偏瘫，不伴失语或感觉障碍；单纯感觉障碍、偏身感觉异常或丧失；发音障碍-手笨拙综合征，表现为轻瘫和舌瘫、说话不清、吞咽困难、手脚精细运动欠灵活；共济失调性轻偏瘫，肢休无力、下肢重于上肢，运动不协调，这些症状常可在2周内消失。

The flow parameters, which controlled the heat transfer phenomena in the coolant channel of the piston, are identified; the experimental facilities and program will be established in accordance with the parametric conditions experienced by a real marine diesel engine. The experimental result for the flow within smooth-walled duct under the reciprocating motion will be used as the reference datum to assess the results for the study of heat transfer augmentation. As an attempt to enhance the cooling performance, the ribs will be installed in the coolant channels which flow was orthogonal mode for the piston moving direction. Finally, the results obtained for the tests with heat transfer augmentation devices will be compared with the smooth-walled test results.

And I say that the universal nature employs them equally, instead of saying that they happen alike to those who are produced in continuous series and to those who come after them by virtue of a certain original movement of Providence, according to which it moved from a certain beginning to this ordering of things, having conceived certain principles of the things which were to be, and having determined powers productive of beings and of changes and of such like successions.

我是说宇宙本性同等地利用它们，而不是说它们同样地发生于那些在连续的系列中产生的人和那些在他们之后通过神意的某种原初运动而产生的人，这一运动按照神意从某一开端向这一事物系列运动，孕育着某些将要存在的事物原则，决定着产生存在、变化和这样一种连续系列的力量。
