On the other hand, real estate director of the Institute of Qinghua University Professor Liu Hongyu proposed, although the overall housing prices will not be any big change, but there will be changes in relative prices, such as the result of "atypical pneumonia", by the purchase of low-density residential Housing people in hot pursuit, a number of high-density project was to examine, bound to a certain extent, long-term impact of price movements of different products.

另一方面，房地产研究所所长清华大学教授刘轰渝提出，虽然整体房价将不会有任何大的变化，但将改变相对价格，如因&非典&通过购买低密度住宅的人穷追猛打，一些高密度的项目审查，必然会在一定程度上，长期影响价格变动的不同产品。

One but reach a rank and not be you how can enjoy an easy and carefree life, there just won't be upheaval in your rank inside proper time, you need pair of ceaseless oneself websites to undertake a structure go up optimize, undertake to visitting a log everyday dog with the analysis, the after leaning relatively to a few ranks keyword that has specific aim undertakes optimizing.

Also being with the metamorphic crystalline basement formed later and suffered the stronger tectonic event and the material composition reforming, being composed of the material with low density and existing the relatively weak intrinsic mechanical system, Huaxia massif was affected by the various tectonic movement in the later period, the layers inside the lithosphere interacted under action of the tectonic force, this led to the material composition and the structure regulated and changed constantly by the magmatism in the crust, underplating and faulting and folding, therefore, the ability to resist the deformation decreased with the every variation.

华夏地块变质结晶基底形成时代晚，并遭受更多更强构造变动与物质组分的改造使之物质组成密度较小，岩石圈先期固有的力学结构系统相对较弱，尤其是后期的地球大系统的历次构造运动都对其施加影响，构造动力作用下引起内部圈层间相互发生作用，导致内部物质成分、结构形态通过壳内岩浆活动、地幔底侵作用、断裂褶皱等不断的调整重组重建而变化，其每一次调整变化，都使其总体抵抗变形能力进一步降低。
