Results show that floes' VC and D at the surface water were closely related to current velocity; and the peaks of VC lag those of the current velocity. The lag variation during ebb and flood tides is 10-30min and 30-50 min, respectively. Current velocity at 50 cm/s is a turning point of D vs. vertical average current velocity, before the point, Dm increases with current velocity, and decreases after the point. Similarly, VC at 75μl/L becomes a critical point in the surface water, below the point, D increases with VC, and above the point, D stabilizes.Δp is D dependent, larger floes have much lower Δp than smaller floes. Both D and Δp of floes affect ω. In the surface water during spring tide and neap tide, a power exponent relationship exists between Δp and D, and ω and D.

研究表明：①长江口徐六泾表层絮凝体体积浓度主要受水流流速影响，再悬浮现象明显，体积浓度过程线滞后流速过程线，落潮期间滞后10-30min，涨潮则滞后30-50min；②小于一定流速时絮凝体平均粒径随流速增大而增大，大于一定流速时絮凝体平均粒径则随流速增大而减小，徐六泾夫、小潮表层絮凝体在50cm/s的垂线平均流速时出现平均粒径与垂线平均流速关系的转折；③徐六注大、小潮表层絮凝体平均粒径在体积浓度75μl/L时出现平均粒径与体积浓度关系的转折，体积浓度小于75μl/L时粒径随体积浓度增加而增大，超过75μl/L时粒径随体积浓度的增加变化不明显；④絮凝体有效密度由粒径大小控制，粒径大，有效密度小，反之亦然，粒径和有效密度共同决定絮凝体静水沉速，有效密度和沉速与平均粒径之间均存在良好的幂指数关系。

The critical point means such a state that all the differences between gas and liquid disappear completely,being a most important parameter of dividing the types of fluid and being widely verified in both theory and practice.Currently,four methods of determining critical point are summarized as follows:①laboratory measurement through examining critical opalescence or recording the bubble point and dew point curves;②empiric relation;③calculation of the bubble point and dew point curves by PVT software;and ④ direct calculation according to thermodynamic theories.

随后对临界点进行确定，临界点是气液一切性质差异均消失的状态，是区分流体类型最重要的参数，并得到了理论和工程应用的广泛验证，目前确定临界点大致有四种方法：①实验测定，通过观察临界乳光现象或记录流体的泡点和露点线；②经验关系式；③通过PVT软件计算流体的泡点和露点线；④利用热力学理论直接计算。

Distance from the origin point to O point was (1.84±0.69)cm,unharmful separation point to O point was (0.05±0.12)cm,muscle entry point to O point was (4.35±0.12)cm.

Adjustments of Second-hand housing policy reduce the deal cost, boosting buyers' expectations; In addition, such change may increase the liquidity of housing, which will speed up investment in new housing and shops. However, the price continue to drop, especially when the new year is coming, more shop investors keep waiting and seeing due to the financial crisis, macro news. Basing on the demand point of view, some demand for living improvement delay the bargain, so did demand for investment due to bad profit-making. As a result, the demand is difficult to start up, while the supply funds is not sufficient, therefore such commercial real estate enterprises will be out of the market due to their inability to meet the finance crisis. Under competitive pressures, the developers will pay more attention to products quality and products differentiation with a view to compete in the market to get a dominant position.

二手房政策的调整降低了购房者的购房成本，刺激了购房期望；另外，二手房政策的改变可能会增加房源的流动性，这样也会加速新房的销售，商铺投资逐渐活跃，但价格表现却成下行趋势，尤其是年关临近，在金融危机面前，商铺投资者多持币观望，从需求者的角度讲，部分改善型需求和投资型需求的购买行为将向后推迟，炒房者将因投机能力下降而不同程度地退出市场，另外，需求难以启动，供给方资金链紧张，部分自有资金不充裕的商业地产企业将面临因无力融资而退出市场的风险，企业因竞争压力大，将更加注重开发产品的品质，提供差异化的产品，以期在市场竞争中占得优势地位。

Aspect, fixes setting between nations , the world subject is the peculiar change period to "peace and development " from "war and revolution "; The capitalism dilation and promptness of socialism camp develop coexistence; Domestic, Mao Zedong critical point in semicolonial and semifeudal society nation crisis and society crisis, be confronted with revolution the mission, has experienced the secondary Chinese tradition society change to modern society with arduousness building.

背景方面，国际上，世界主题是从"战争与革命"向"和平与发展"转变的特殊时期；资本主义的扩张与社会主义阵营的迅速发展并存；国内，毛泽东处在半殖民地半封建社会民族危机与社会危机的紧要关头，面临着革命与建设的艰巨任务，经历了中国从传统社会向现代社会的转变。

On the basis of distributive shapes of point collection on the Poincare section, define three indexes to quantitatively describe the distribution of point collection. Which are distance between two adjacent points, diffused angle and distance between every point and center point of point collection.

以庞卡莱截面上RR间期序列的点集分布形式为基础，提出点集中相邻点间距离、扩散角度和点到点集中心距离三项指标，用以定量地衡量点集的分布形式。

Firstly, according to this character, primacy central point is detected by the exploring extremum method in the windows of 3×3 pixels. Then, basing on this central point, approximate normal line at ±45°、0°and 90°angle are drew.if the minimums of normal line is at central point and the difference between the minimums and the maximum in the normal line is more than the threshold, this point is considered to the edge point of image.

首先，在3×3象素的窗口中，如果中心值为最小值，则以该点为基础，以±45°、0°和90°方向作为近似法线带，然后判断该法线上的象素最小值是否在切点上（即是否在法线的中心点上），再通过检验切点与轮廓法线上亮度极大值的差值是否超过阈值，来判断切点是否为边缘轮廓上的点。

While it is usually impractical for the marshallate to measure blade weight directly by weighing the sword before the basket hilt, cross, or pommel weight is attached, the linear density of the blade (its weight divided by its length) can be estimated fairly easily by weighing the finished sword, locating the point on the blade at which it balances, and measuring the distance from the point of balance to the tip, from the point of balance to the hilt, and from the point of balance to the point where the additional weight (the basket hilt, cross, or cross plus pommel weight) is attached to the blade.

而这通常是不切实际的为marshallate来衡量的刀身Weight直接由称重剑前一篮子的Hilt ，交叉，或pommel重量是重视，线性密度的刀片可估计相当容易称重成品剑，定位点的叶片在它的结余，以及测量距离平衡点，以尖端性，从平衡点到极限和从平衡点以点的额外重量（篮子的Hilt ，交叉，或跨加pommel重量）是连接到刀片。
