Methods: Totally 2200 patients with varicose vein received surgical treatment in our hospital from July, 2000 to January, 2006. 1802 cases were treated by endovenous laser therapy combined with transilluminated powered phlebectomy.82 cases were treated with radiofrequency endoveous occlusion combined with TIPP,218 cases treated with limited invaginated vein stripping and foam sclerotherapy.

回顾性分析2200例下肢静脉曲张外科治疗的临床资料，其中1802例患者采用激光联合透光直视旋切术，82例患者采用射频联合透光直视旋切术，218例患者采用选择性内翻式大隐静脉剥脱联合硬化剂治疗或透光直视旋切术，其余98例患者分别采用激光、高位结扎、射频处理大隐静脉主干，辅以曲张静脉团的手术切除、激光、电凝、皮下连续缝扎或硬化剂注射方法治疗。

Therefore it can be used for surface hardening and hardening of localised areas of metallic parts by "outrunning" the thermal conduction of heat deeper into the part or to surrounding areas.

因此，可颐于表面硬化，和局部地区的金属部分硬化的&没错&的热传导热深入到部分或周边地区。

The surface roughness of the laser shock peened medium has effect on the high frequency of laser-generated surface acoustic waves. As the impact times of the laser shock peening increase, the surface roughness has little effect on the dispersion of laser-generated surface acoustic waves. From the theoretical curve and experiment curve, it can ...

本文研究的结果，可对研究样品激光冲击硬化后残余应力、晶粒方向改变和错位密度增加分别对激光声表面波色散影响提供了基础，并对利用激光声表面波的色散特性来研究激光冲击硬化材料冲击层材料性质的变化具有一定的意义。

The serums SM levels are closely related with the known atherogenic risk factors, and they are also an important risk for atherosclerosis.

血清SM水平和已知的致动脉粥样硬化危险因子密切相关，提示SM可能是导致动脉粥样硬化发生的重要因素。

Compared with polycrystalline Cu, the as-cast single crystal copper shows better plasticity and extensibility, and has a lower electricity resistance. Its elongation of cold rolling can reach 6100% without any cracks in the edges. The single crystal copper exhibits more serious work hardening in wiredrawing. The plasticity and ...

结果表明：和多晶铜相比，单晶铜在铸态时具有良好的塑性和较低的电阻率，并具有优异的室温延展性，其延伸率可达 6 10 0 %以上；冷拉拔加工后单晶铜表现出更大的加工硬化现象，但采用合理的退火工艺可使其加工硬化得到缓解。

In the samples containing aluminum sulphate, some ettringite crystalparticles are formed, which do not match with dihydrate gypsum crystals and increase thedefects in the hardened plaster. The strength decreases sharply with increase of aluminumsulphate amount.

硫酸铝的引入，使石膏浆体中生成部分钙矾石晶体，钙矾石晶体与二水石膏晶体不匹配，从而增加了硬化体内部的缺陷，因此，随着硫酸铝掺入量的增加，硬化体强度的降低比较严重。

OBJECTIVE: To compare the rheological properties of stress relaxation in normal and atherosclerotic animal model of ascending aorta, and to identify the effects of atherosclerosis on the stress relaxation properties of ascending aorta.

目的：比较正常和动脉粥样硬化动物模型升主动脉的应力松弛流变特性，确定动脉粥样硬化对升主动脉应力松弛特性的影响。

To compare ascending aorta creep characteristics of the normal and atherosclerotic animal model to identify the effect of atherosclerosis on ascending aorta creep characteristics.

比较正常和动脉粥样硬化动物模型升主动脉的蠕变特性，确定动脉粥样硬化对升主动脉蠕变特性的影响。

The advantage of the proposed method is that the elastic moduli of hardened cement paste are related to the volume fractions and elastic moduli of the constituents in a quantitative manner, which lays a theoretical foundation for optimization design of cement paste.

分级模拟方法的优点在于以定量的方式将硬化水泥石弹性模量与各组分的体积分数和弹性模量联系起来，为硬化水泥石优化设计提供了理论依据。

To test the hypothesis that concentration polarization of atherogenic lipids may occur in the arterial system and play an important role in localization of atherosclerosis, we simulated and measured in vitro the luminal surface concentration of low density lipoprotein in local stenosis at the distal end of carotid artery by number simulation and laser scanning confocal microscopy, then we designed carotid stenosis model to test the role of LDL concentration polarization in atherogenesis.

低密度脂蛋白(low density lipoprotein， LDL)浓度极化可能是动脉粥样硬化局灶性的重要原因，本文以狭窄血管远心端为研究对象，探讨LDL浓度极化对动脉粥样硬化发生、发展的影响。

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。
