不变化

While the material machined hardness is lower than HRC50, the changing rule of cutting force and cutting temperature was accordant with the common cutting theory.

当工件材料硬度低于HRC50，切削力和切削温度的变化规律符合普通的金属切削理论，硬度超过HRC50则切削力和切削温度的变化规律大不相同。

The real tangential velocity fluctuation indicated that there existed an instability of swirling flow in the cyclone.This instability resulted in the rotation center of the swirling flow deviating from the geometric center of the cyclone,which produced the quasi-periodic oscillation of swirling flow and gave the real tangential velocity fluctuation.

瞬时切向速度的变化反映了旋风分离器内旋转流的不稳定性，这种不稳定性导致了旋风分离器内旋转流的旋转中心与几何中心不重合，旋转中心围绕着几何中心摆动，由此造成了瞬时切向速度随时间的类周期的波动变化。

Benchmark prices in高价房rapidly improve at the same time,高价房structure is changing fast: 9000 yuan / sq m of real estate continued to decrease in price of room高价房with the gap gradually opened, 9000 -10000 yuan / square meter to gradually increase the proportion of高价房, Link has become the region with the main properties for sale, may fail to get too long, within the inner ring will be the elimination of 9,000 / sq m of real estate; 15,000 yuan / square meter demand volume has increased year by year to illustrate the market's acceptance of ultra-高价房enhance customer requirements change.

基准价格高价房迅速改善的同时，高价房的结构正在迅速发生变化： 9000元/平方米，房地产继续减少在房价之内高价房的差距逐渐开放， 9000 -10000元/平方米，以逐步提高比例的高价房，链接已成为区域内的主要性能出售，可能过不了太久，内环内将消除9000 /平方米的房地产； 1.50万元/平方米的需求数量逐年增加，说明市场的接受超高价房提高客户的需求变化。

The posterior length of the dental arch changed significantly (P.001). The maxillary and mandibular arch shapes didn't change before and after treatment.

结果：上、下牙弓宽度在矫治前、后有显著差异(P.05)；上、下牙弓长度治疗前、后尖牙长度变化不明显，而第一磨牙长度具有显著性差异(P.001)；治疗前、后，上、下牙弓形状无明显变化。

The length of the anterior bundle was maxium at 90° of the elbow flexion, the length of the posterior bundle varied with the change of the angle of elbow flexion, and a transverse bundle was unchanged.

前束在肘关节屈曲90°时最长，此时亦为最紧张状态，后束则随肘关节屈曲角度增大而逐渐变长，而斜束的长度不随肘关节屈曲角度的变化而变化。

With the implement of urbanization, there're thousands of small towns to construct. However, corresponding criterion still haven't come out ,such as water and drainage quota, which result in no standard to refer to, what's more, absenting systemic researches on variation rules and coefficients of total water and wastewater in towns. Therefore, the construction of many towns takes on luxury evidently.

随着城镇化战略的实施，目前我国有数以万计的小城镇亟待建设，但是，与小城镇建设相匹配的基础设施建设规范尚未出台，致使小城镇给排水工程建设过程中无标准可依，更缺乏小城镇用水量和排水量变化规律以及变化系数的系统研究，贪大求全、不讲科学地追求高标准的现象较为明显。

There is barely a vegetable that they don't grow: in summer, the beds are brimming with zentai suits ery, christian louboutin boots , flowers and produce from artichokes and asparagus to tomatoes, pumpkins, courgettes, various varieties of lettuce and, a favourite, Jerusalem artichokes, which he says were a French staple during the second world war and are "so, so much more delicious than a potato -just worlds apart".

从志愿填报到志愿决策就发生了根本性的变化，对我们个人发展影响也发生了根本性的变化。在过去，我们填报志愿完全是一个事务性的，到现在，如果我们选择了一个在高考填报志愿的时候，专业没有选择合适，学校也不是很合适的情况下，出去找工作就比较困难。这就是从志愿填报变成了现在的志愿决策。

Objective:To investigate the dynamic changes of immune function indexes of erythrocyte in the dialysis process of patients subject to blood dialysis, and to study the contribution of dialysers with different biocompatibilities to the changes.

目的：了解血液透析病人透析过程中红细胞免疫功能指标的动态改变及不同生物相容性的透析膜对其变化的影响。方法：分别采用铜仿膜、聚砜膜、聚甲基丙烯酸甲酯膜，观察了透析过程中不同时相的红细胞免疫功能指标RBC－C3b和RBC－IC的变化。

There were also conspicuous accumulations of membrane bound esicles, dense bodies, myeloid figures, and areas of esicular in Schwann cells. These changes were seen with dialyzer exposed medium or with medium containing patient serum but not with controls or with medium incubated in plate dialyzers.

这些变化见于使用了暴露于透析器的培养基的DRG，或使用含有病人血清的培养基的DRG，但变化不发生于使用对照用组织培养基或者在平板透析膜中孵育的DRG。

Epidotes from different samples show considerable compositional variation,whereas those from the same sample are quite similar in composition, indica-ting that their composition is related.

s=0.23—0.37，但多为0.30—0.32，在不同样品中绿帘石成分变化很大，但同一样品中绿帘石变化不明显，说明其成分与全岩成分有关。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。
