From the microcosmic structure of securities market,the problems of stock market liquidity and bargain amount change were analyzed. The dispersed model of amount dynamic state of bargainers was discussed. By neglecting price change,an appropriate proportion of bargainer quantity of both buyer and seller is the lowest standard of the market liquidity. The time achieving stable market liquidity has relation to parameters for bargainer to leave the stock market. Finally,simulation calculation of bargainer quan...

为此，本文把现代汉语动词按其跟相关语义成分的依存关系首先分为动作动词、致使动词、心理动词、性状动词、关系动词5大类，以确定各主事动元的类别；第二层级按动核所带动元的数量，对各类动词进行下位分类，分别得出一元动词、二元动词、三元动词，以显示动核所带动元的数量：第三层级按动核所带动元的性质和数量把现代汉语动词分为24个基本类，以确定动元即必有语义成分的基本类别和数量。

For radians, these functions are found in boost/units/cmath.hpp These behave as one expects, with trigonometric functions taking an angular quantity and returning a dimensionless quantity, while the inverse trigonometric functions take a dimensionless quantity and return an angular quantity

对于弧度，这些函数定义在 boost/units/cmath.hpp 。这些函数就像你想的那样，三角函数以弧度数量为参数返回一个无量纲数量，反三角函数以无量纲数量为参数返回一个弧度数量

A predator model with refuge and toxicity is studied. By constructing a suitable Dulac function, it is shown that there is no limit cycle in the first quadrant, thus the globally stability of the equilibrium is proved. Further more, the paper analyzes the influence of refuge, toxicity and harvesting. It is amazing that ① if the death rate of predator is big or the harvesting effort is big, the existence of the predator is unrelated with refuge; if the death rate of predator and the harvesting effort are small, and the refuge is small enough, the population of both species is increased as the increase of refuge;② if d2=0, the increase of d1 has no influence on the prey population, while the population of predator is decreased.

研究一类有避难所、毒素作用和外界捕获影响的捕食系统，通过构造恰当的Dulac函数，证明系统在第一象限没有极限环，从而证明了平衡点的全局稳定性；分析了避难所、毒素、捕获作用对该系统最终种群数量的影响，发现：①当捕食者的死亡率大或其被捕获得多时，两种群的绝灭与避难所的存在无关；当捕食者的死亡率小、被捕获得多且避难所足够小时，随着食饵避难所的增加，捕食者种群数量也随之增加；②当毒素d2=0时，毒素d1的增加对食饵种群最终数量没有影响，而使捕食者种群数量下降。

The results show that the addition of certain manganese in high chromium cast iron leads to a re-partitioning of alloy elements between austenite and carbide and a dropping in equilibrium phase transformation temperature although it's inappreciable for the influence of manganese on mass fractions of every phase in this cast iron. There is about 87 percent ledeburite under thermodynamic equilibrium condition and 23 to 32 percent M7C3 type carbide under thermodynamic non-equilibrium condition in the microstructure of 3C-l5Cr-4Mn-0.75Si system high chromium cast iron. Furthermore, the improvement of austenite stability and hardenability of manganese alloyed high chromium cast iron may been expected because there is a substitution between manganese and chromium that has been suggested by thermodynamic calculations.

结果表明，锰虽然对高铬铸铁中的各相数量影响不大，但一定数量的锰存在促使合金元素在奥氏体和碳化物两相中的重新分配，并降低平衡相的转变温度；在平衡条件下3C-15Cr-4Mn-0.75Si系高铬铸铁中菜氏体数量约占87%，而非平衡条件下M7C3型碳化物数量在23%-32%之间，且奥氏体中锰铬互替现象保证了奥氏体的稳定性和加锰高铬铸铁的淬透性。

During experimental initial stage, whether control or trials, the number of heterotrophic bacteria and vibrios in pond waters increased. After Cefalexin was used again, the number of heterotrophic bacteria and vibrios in all trails' pond waters were obviously lower than that of the control, and the number of heterotrophic bacteria and vibrios in control's pond waters were obviously raised.

在试验初期，无论是对照组还是施用头孢氨苄的各试验组，育苗水体中的总异养菌数量和弧菌数量都呈现出较为明显的上升趋势；在第二次施用头孢氨苄后，各试验组的异养菌总数和弧菌数量的增幅明显低于对照组（或出现异养菌总数和弧菌数量缓慢下降），而对照组异养菌总数和弧菌数量则呈现显著的上升。

The following conclusions are drawn. 1 The orbit parameters that have relatively greater influence on the number and latitudinal distribution of annual occultation events are orbit inclination, orbit height, Right Ascension of Ascending Node and Argument of Perigee in turn. All four parameters have little impact on the longitudinal distribution of annual occultation events. 2 The orbit inclination of Transmitting Satellite and Receiving Satellite impacts both LEO－LEO occultation events number and their latitudinal distribution most. The number of occultation events reaches the maximum as the sum of the two inclination angles nears 180 degrees. The one that far away from 90 degrees of the two inclination angles determines the latitude range of the occultation events. 3 LEO－LEO occultation events number reaches a maximum when the heights of TS and RS are the same, and it reaches the maximum when the heights of TS and RS are 600 km . 4 The RAAN of TS and RS has a great influence on the LEO－LEO occultation number, but has little influence on occultation distribution.

结果指出：1对一年掩星事件数量及其纬度分布影响大的轨道参数依次是轨道倾角、轨道高度、升交点赤经和近地点角距；而这些参数对一年掩星事件的经度分布影响都不大；2发射卫星和接收卫星倾角之间的相互关系对掩星事件数量和纬度分布影响最大，两卫星倾角接近互补时掩星事件最多，两颗LEO卫星中与90°相差较大的倾角决定了LEO－LEO掩星事件的纬度分布范围；3发射卫星和接收卫星处于同一轨道高度时，LEO－LEO掩星事件数取得极大值，发射卫星和接收卫星都采用600 km的轨道高度，一年LEO－LEO掩星事件数最多；4 发射卫星和接收卫星升交点赤经的相互关系对LEO－LEO掩星事件数量影响很大，发射卫星和接收卫星升交点赤经之差为120°或240°时掩星事件数量最多，RAAN对掩星事件纬度和经度分布影响不大；5近地点角距对掩星事件数量和分布影响都不大。
