弹簧

The dissolution of offload valve spool: Using circlip pliers remove the valve core and valve located at the junction of the circlip, and then pipe clamp screwed up spool, remove the inside of the cylinder, valves, O-rings, U-type ring, spring and immersed into the cleaning agent, and then split out the valve on the inlet, the whole body into the soaking, this time, the demolition process by Dutch valve has been completed.

拆减荷阀阀芯：用卡簧钳取下位于阀芯与阀体连接处的卡簧，再用管钳拧出阀芯，取出里面的气缸、阀片、O型圈、U型圈、弹簧并放入清洗剂中浸泡，再拆出阀体上的进气口，将整个阀体放入浸泡，此时，减荷阀的拆卸过程已完成。

Firstly, the establishment of model requires sophisticated neurointerventional techniques and costly interventional materials(sacculus, minikin circlip ring, endovascular electrocoagulation), it not only consumed time but also increased the resesrch expense ; Secondly, although the Massoud model is the first successful model that contain the nidus, but it is far from mimicking the high-flow fistulae frequently observed in a brain AVM; Thirdly, the rapid spontaneous thrombosis result in fistula occlusion in a short time;Fouthly, the model's natural course and the long–term patency of fistula are unclear;Currently the model is only used for the short-term research.

但Massoud模型目前存在以下主要缺点：第一，模型的建立需要复杂的神经介入技术和昂贵的介入材料(球囊、微弹簧圈、血管内电凝等)，操作费时，又大大增加了研究费用；第二，Massoud模型虽然首次具备了畸形血管团，但它远不是我们临床上常见的含有高流量动静脉瘘的脑AVM；第三，颈动静脉吻合口自发性血栓形成进而导致引流静脉闭塞的机率很高；第四，Massoud模型的长期自然过程和动静脉吻合口的长期通畅性尚不清楚，目前仅仅作为急性期模型。

We can guarantee to clamp the intensity of strength by adjusting the tight intensity of the spring.

我们可以通过调整弹簧的张紧程度来保证夹紧力的大小。

According to the record of ancient document s, this paper gives the possible structure of Li Lan's steelyard clepsydra, and demonstrates the principle for the stabilization of average flow velocity.

根据古文献记述，李兰秤漏很可能是使用弹簧联结权器和秤钩，以达到平均流速稳定的目的。

In the latter mode, the rear, unused part of the magazine housing is closed by a spring-loaded dust cover.

在后一种模式下，后方，杂志的房屋未用部分关闭了弹簧式防尘罩。

Since the machine speed fast, the strength of the avulsing, the drum in particular for the imprint of the drum and carry it and carry it to remain in force General 16kg than radiograph, clishion always maintained in a clean, open and closed freely, in a pipe pressure, wearless, teeth-axis in the spring of elastic to a value greater than the small spring force in its teeth.

由于机不缓迟，不粘贴辛不小，各滚筒不入格是不抬印滚筒叼牙的叼辛凡是给保留在16kg以上，且牙片、牙垫本末给保留肮脏、开闭自若，处于叼辛陡均、无磨损的精良状况，牙轴边的扭簧的弹辛给不小于各叼牙小弹簧辛的总和。

Three weeks ago, the USGA informed Callaway Golf that these 13-degree models distinguished by a raised "dash" in the letter "B" of the word,"Big" on the club's sole plate were considered "hot" because they exceed the .830 limit of the coefficient of restitution, otherwise known as spring-like effect.

3个礼拜以前， USGA通知Callaway说这些 13-度的型号以B字母中间的凸起的破折号，和"Big"单词在S面上为典型特征－被认为太快，因为它们超过了。830 的coefficient极限，也就是所说的弹簧效应。

Spring collars are common, and some benefit from the use of special tools.

较常见的是弹簧圈头。

The exact solution of the period is got by using the first kind of complete elliptic integral.
