XD-2003 strap machine is changed from XD-2002 machine which has a cast aluminium on the bed,making the screw,screwtube and speed reducer keeping concentric.the V-model manger on the bed is lower than the flat on which the speed reducer is fixed,the components are finished machining by machine tool.guaranteeing perpendicularity, degree of balance.speed reducer,screw and screwtube is fixed on the base,and the screwtube is in the mini-manger,then ensuring axis keeping concentric with sheath,screwtube feed opening has a chromium hard-wearing sheath,which can improve the lifetime of the screw and screwtube to threefold or to fourfold.

XD-2003 型塑料打包带机组，是在XD-2002型机组的机座上安装了一个铸铁机座，使螺杆，螺筒和减速机保持同心，座上的V型槽比安装减速机的平面低，其部件都是经过机床精加工完成的，保证了垂直度和平衡度。减速机和螺杆、螺筒置于底座上，且螺筒卡在微型槽内。确保轴与套保持同心，螺筒下料口处设有高铬耐磨衬套，这样可使螺杆、螺筒的寿命提高3-4倍。

At this time, is full of water pumps, if the long run, would lead to rising temperature in the pump, pump shell, the bearings will be fever, severe heat may make the body deformation, known as the "stuffy head," at this time Head to the maximum value, when the valve to gradually open, traffic will gradually increase, shaft power also slow the increase.

此时水泵里是充满水的，如果长时间的运行，会导致泵内温度不断升高，泵壳，轴承会发热，严重时可能使泵体热力变形，我们称为&闷水头&，此时扬程为最大值，当出水阀逐渐打开时，流量就会逐渐增加，轴功率亦缓慢的增加。

BW-WJ universal angular corrugated compensator is made up of structures such as one (or more the two namely composite universal angular type) bellows, forelock, axis, hinge plate, universal loop and standing board etc. It can absorb angular displacement in any plane and bear the pressure or thrust of the bellows. When large compens-ation is required, two or more compensator can be assembled and utilized in series. Besides, the product can also be pre-pressed, pulled or reversed when installed.

BW-WJ型万向角向型波纹补偿器由一个（或二个及以上，即复式万向角向型）波纹管、销、轴、铰链板、万向环和立板等结构件组成，能吸收任意一平面内的角位移并能承受波纹管压力推力的膨胀节，当需要大补偿量时，可采用两个或以上组合分段串联使用，并对产品预压缩、拉伸或扭转安装。

Journal bearing vibration on turbine units of peak load regulation often occur obvious changing in short time because of its load change. if this change excess some standards, it might lead to abnormal shutdown of the the unit.

调峰机组由于经常需要在变负荷状态下运行，机组轴系振动往往会在短时间内产生变化，如果这种变化超过允许标准，将导致机组非正常停机，不能完成调峰任务。

The distribution of the growth-associated protein (GAP-43) which is close related to the axon regeneration was examined by immunocytochemical method in the adult rat brain and the rat parietal lobus injuried into which the fetal cerebral suspension was lransplanted.

在发现流式细胞计可用于神经科学的研究后，用FCM研究了大鼠脑发育过程中细胞周期的变化和胚胎大脑细胞移植到成年大鼠顶叶后对宿主顶叶脑细胞分裂的影响；由于生长相关蛋白(GAP-43)与轴突再生密切相关，用免疫细胞化学法研究了GAP-43在成年大鼠脑内的分布及顶叶损伤植入胚胎大脑细胞后GAP-43的变化。

In most applications, CSB bearings can be fitted by press. For this procedure, a mandrel and a press machine are used, it is forbidden to hit the bearing in order to avoid deformation of bearings. The housing inner side should smooth without contamination.

通常情况下，轴承可以采用压力装配的方式进行安装，装配时应采用芯轴慢慢压入，禁止直接击打轴承以免产生变形，装配前应确保座孔内表面光洁无异物。

The carbonate reservoir is characterized by the fact that the azimuth of fractures is related with structural axis, the developmental extent of fractures and structural location are close related to dip of structure, low-dipping structural axis has not growth fractures. Otherwise, growth fractures, density of fractures are related thickness of layer, more thickness, then less density of fractures. Intra-fracture of layer is main. Some marlstone and anhydrite barriers exist in the reservoir, and become some non-connected oil-water system.

结果表明：碳酸盐岩油藏为裂缝的发育程度与构造位置及构造倾角的大小有关，构造轴部倾角小裂缝不发育，构造翼部倾角大，裂缝发育；裂缝发育密度随着单层厚度增加而逐渐减小；裂缝以层内缝为主，穿层大裂缝少；油藏中存在若干泥质灰岩和膏盐的隔夹层，形成多个连通不畅的油水分布系统。

Increased levels of monoamines in the synapse affect the hypothalamic–pituitary–adrenal axis 56 and reverse some of the long-term effects of stress.

在突触内单胺水平上升，影响下丘脑-垂体-肾上腺轴，逆转一些长期的紧张效应。

When N=6, the electron transfer was similar to the case of N = 4, but inner layer electronic local was weakened so that parts of electrons in S layer was excited into P electrons, increasing axial electron mobility, meanwhile more performances of sp2 hybrid orbital formation were completed.

在N=6的图中，电子转移情况类似N=4的情况，但内层电子局域性有所减弱，导致部分s电子被激发成p电子，增大轴向电子流动性，同时可表现更多的sp2杂化轨道的形成。

Significantly stretched wheelbases, roomier interiors and more attention-getting styling are the big news from the new Subarus that go on sale around August.

新款斯巴鲁带来了重大新闻，该系列车型的重要的特征是轴距加宽、厢内宽敞和款式引人注目；约在2009年8月份上市销售。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
