Property- developers: 1 Mr. REN Zhiqiang, chairman of Huayuan, said recently that developers now sit on 360mn hectors of land, which will lead to 250mn sqm house inventory by 2009 year end, roughly 1/3 of average annual supply. 2 Mr. GU Yunchang, a deputy head of China Real Estate Association , said that 1Q09 sales was from the pent-up demand from 1st house buyers, while people trying to upgrade 1st houses or buy 2nd houses have not stepped in.

华远地产董事长任志强最近称全国开发商手里待开发的土地约有3.6亿公顷，全年房屋库存也会有2.5亿平方米，这意味着全国每年房屋销量的1/3将处于库存状态；2）中国房地产业协会副会长兼秘书长顾云昌称09年第一季度的销售量主要是依靠一手方购买者的阿刚性需求推动的，而真正购买大的房子以及二套房购买者则比较少。

In this paper, we had developed a set of new procedures for constructing a set of orbitals with thoroughly separated π and σ orbitals, highly localized, symmetrical, orthonormalized and have correct electron occupancies to the rigid molecules with C〓 symmetry.

Though a Benedictine himself born in Aquitaine and trained at Saint-Seine near Dijon, Benedict was imbued with the rigid austerity of the East, and in his Abbey of Aniane practiced a mode of life that was severe in the extreme.

虽然本笃本人出生在阿基坦和训练有素的圣第戎附近的塞纳河，笃是充满刚性紧缩的东方，并在他的修道院Aniane实行的生活模式是严重的极端。

Ccording to the characters of porous metals, a new effective bulk modulus formula with simpler expression was obtained by considering the heat exchange between the metallic skeleton and air in pore on the basis of phenomenological Biot-Allard model, therefore an extended sound absorption model was put forward.

bstract 根据金属骨架多孔材料的特点，在Biot-Allard刚性骨架多孔材料内流吸声模型的基础上，考虑金属的热导特性，推导出一种新的、形式较简单的有效体积模量表达式，从而得到了一种扩展的吸声模型。

Focusing on severe wheel flange/rail side wear and a series of derailments of tramway vehicles with independently rotating wheels, an investigation has been carried out by comparison against solid wheelsets. Based on MATLAB/SIMULINK and a self-developed simulation model considering the IRWs, derailments have been simulated with results of possible causes of such derailments. Efforts have been made to fulfill comprehensive treatment of controllable factors such as the wheel profile, lubrication, clearance between check rail and high rail etc.

针对目前具有独立轮转向架的低地板面轻轨列车所发生的脱轨问题和轮缘严重磨耗间题，从轮轨系统的基本关系出发，分析了传统刚性轮对与独立轮对的导向机理和特点，建立了具有独立轮特点的计算机仿真模型，采用MATLAB/SIMULINK仿真工具计算模拟了实际脱轨现象，并对各种可能导致脱轨和轮缘磨耗的因素进行了分析。

Based on Mononobe-Okabe＇s postulation and the reasonable consideration for the restricted pore water, a first-order differential equation of the dynamic active earth pressure on rigid retaining walls with submerged backfills in the traaslational movement mode under earthquake loads is set up by using the method of level-layer analysis.

基于Mononobe-Okabe假定，在合理考虑土体孔隙中受限水含量的基础上，利用水平层分析法推导了填土中有地下水时刚性挡土墙平移模式下的动主动土压力强度的一阶微分方程，并求得非线性分布解：探讨了地下水位、受限水含量、填土的内摩擦角、墙背的摩擦角和地震系数等参数对土压力强度分布、合力作用点高度以及倾覆力矩的影响。

As one of classical examples of semiactive control system, variable dampers are widely used for structural control.

作为半主动控制系统的经典范例之一，变阻尼控制系统已经在结构控制领域得到了广泛的应用，但是近来的研究显示变阻尼控制对于抑制柔性结构的地震反应是适宜的，而对于刚性结构则是不适宜的。

In the end, Based on the conception that the simple beam at ultimate rotates rigidly around the plastic hinge in the midspan when the beam fails because of bending, the formula for calculating the stress in the external tendons and the ultimate anti-bending capacity of the beam in the cases of different deviators have been developed.

最后，基于抗弯承载力极限状态下的简支梁可视为梁体绕跨中等曲率塑性铰发生刚性转动的假设，推导了在各种转向块布置情况下求体外预应力筋的变形和梁的跨中挠度，进而求得梁的极限弯矩的简化公式。

Therefore, for improving the accuracy of exceed slender axle on turning,must need to do with the lathe fixture and cutting tool for further improvement. In order to reached the requirements of precision machining,in machining process must use follower rest、flexible active thimble、space block and bracket etc fixture and assistive device.

超细长轴在车削加工中承受自身重力、切削力、高速旋转产生的离心力的作用，极容易出现振动与弯曲变形现象，增大轴的几何形状误差，而超细长轴的轴向尺寸较大，直径较小，热扩散性及刚性差，受切削热作用会在轴向发生线性膨胀，若在轴向的伸长量无法得到消除，轴将受迫弯曲，从而影响轴的精度。

Cyclodextrins, cyclic oligosaccharides commonly composed of six, seven or eight respectively D-glucopyranosyl units connected by α-(1, 4)-glycosidic linkages, have the ability to form inclusion complexes with a wide range of substrates for their particular structures. With proper rigidity and flexibility, excellent mechanical stability and biocompatibility, cyclodextrins are good choice of material in molecular imprinting technology.

环糊精是由六，七或八个D-吡喃葡萄糖单元通过α-1，4 糖苷键连接成的环状低聚糖，由于其特殊的结构使其可以包结一系列的底物，加之具有适当的刚性、柔性、机械稳定性，良好的热稳定性和生物相容性等使其成为分子印迹技术优秀的选择材料。
