Based on the simulation data, the effects of clearances, damping coefficient and the rotation speed on the dynamic behaviors are studied: compared with ideal mechanisms, mechanisms with clearances are less stable; as for mechanisms with clearances, when the crank rotates at the speed of 100rad/s, the actual clearances are always above the radium of clearances, axle pin and axle cover keep contact throught the rotation; when the crank rotates at the speed of 20rad/s, mechanisms are in an unstable state, at an angle of about 300, the actual clearances are below the radium of clearances, pairs lose contact, which results in collision between them; with the speed of 20rad/s, when damping coefficient is assumed 175Ns/m, distinct separation and collision happen between pairs; when damping coefficient is assumed 220Ns/m, separation and collision are controlled.

在含间隙机构中，当曲柄以100rad/s转动时，运动副间隙始终大於半径间隙，轴销与轴套始终保持连续接触；当曲柄以低速20rad/s转动时，系统处於极不稳定的震荡状态，在转至300°左右时，运动副间隙小於半径间隙，脱离接触，发生明显的分离碰撞现象。在含间隙机构中，曲柄以低速20rad/s转动，当取法向阻尼系数为175Ns/m时，副元素发生明显的分离碰撞现象；当取法向阻尼系数为220Ns/m时控制了副元素的分离，副元素一直处於连续接触状态。

Butt Weld and docking and corner combinations Weld, in Weld ends located arc plate and extraction plate in igniting board then leads to the welding seam, joint halfway shall weld joints in front of 2.0 mm Department Firing arc, welding pieces after preheating rod will return to weld the origin, pool filled to the required thickness, before forward welding; Welding speed : Isokinetic welding requirements to ensure weld thickness, width uniform, which masks to look for hot metal and slag bath equidistance (2-3 mm)%; Arc welding rod length : different models and determined that the general requirements of arc length is stable, acid electrode generally 3-4 mm, 2-3 mm normally alkaline electrode%; Welding perspective : According to determine the thickness of two pieces of welding, welding angle has two aspects : First, the angle between the direction of the rod and welding of 60-75 ; The second is the angle between two electrodes and welding around, the same thickness as welding, welding and welding pieces incident angle of 45 ; When the thickness ranging from welding, welding electrode and thick and thin pieces of welding electrode side angle greater than the angle between the side pieces; Arc : admission to the end of each weld should be filled crater, in the direction opposite to the direction of the back-arc welding, arc welding unchanged inside pit in 1974, to prevent the crater bite of meat.

对接焊缝及对接和角接组合焊缝，在焊缝两端设引弧板和引出板，必须在引弧板上引出后再焊到焊缝区，中途接头则应在焊缝接头前方15～20㎜处打火引弧，将焊件预热后再将焊条退回到焊缝起始处，把熔池填满到要求的厚度后，方可向前施焊；焊接速度：要求等速焊接，保证焊缝厚度、宽度均匀一致，从面罩内看熔池中铁水与熔渣保持等距离（2～3㎜）为宜；焊接电弧长度：根据焊条型号不同而确定，一般要求电弧长度稳定不变，酸性焊条一般为3～4㎜，碱性焊条一般为2～3㎜为宜；焊接角度：根据两焊件的厚度确定，焊接角度有两个方面，一是焊条与焊接前进方向的夹角为60～75 ；二是焊条与焊接左右夹角有两种情况，当焊件厚度相等时，焊件与焊件夹角为45 ；当焊件厚度不等时，焊条与较厚焊件一侧夹角应大于焊条与薄焊件一侧夹角；收弧：每条焊缝焊到末尾，应将弧坑填满后，往焊接方向相反的方向带弧，使弧坑甩在焊道貌岸然里边，以防弧坑咬肉。

Walk to the high side of the pillar and jump up to grab the grating. Traverse to the middle of the last square of grating. Then drop onto the other angled pillar. Slide back, grab the edge, and let go to drop through the break-away tiles in the cathedral dome, to land on a catwalk below.

此时脚下的高台是稍斜的，走到较高的一端，面对眼前另一斜柱，原地跳抓住头顶的铁丝网，并向前悬荡一格，松手会滑落到一处碎地板上，之后就会随碎地板落到地下的诸圣堂中的一处高架通道上。

If the water content of the raw material is high ,change the chain wheel of the motor into the big oneand vice versa.

如果原材料含水量大的时候，把进料处的拨料器的电机链轮换成随机配的大链轮，当含水量小的时候，把进料处的拨料器的电机链轮换成随机配的小链轮。

He had a house, indeed, but without furniture, so he could not lodge me; but he got me a lodging at Mr. Read's, before mentioned, who was the owner of his house; and, my chest of clothes being come by this time, I made rather a more respectable appearance in the eyes of Miss Read than I had done when she first happened to see me eating my roll in the street.

虽然他有一所住处，但是没有家具，所以不能让我寄宿，但是他为我在前所提及的李得先生处找到一处寓所，他是基梅尔的房东，而此时我的箱子和衣服也都到了，在李得小姐眼中我的打扮，比较她第一次碰见我在街头吃面包时的形象要高雅一点。
