The instability originated in the upper R_B-like convection zone develops to larger region with the increase of Grashof number, and the number of non-axi-symmetric circulations decreases. When Grashof number exceeds another critical value, cooling air may invade the cavity and flow toward the shroud, the circulations decrease to one pair occupying the whole cavity in radial, thus these two zones are merged into one. The core structures in the cavity rotate against the disks, while the structures keep no change at the case of periodic oscillatory flow. With the Grashof number rises, the flow undergoes stable, periodic, periodic with cool air invading, quasi-periodic and ultimately to chaos.

离心浮升力是造成非等温轴向通流旋转盘腔内流动不稳定的主要因素，而哥氏力的存在加剧了流动不稳定性，导致流场失稳提前发生，而且在哥氏力的作用下流线发生偏转，盘腔内r-θ面出现了旋向相反的对涡，流动结构更加复杂化；随离心浮升力的继续增加，r-θ面的对涡减少，当其超过某一临界值后部分冷流体侵入盘腔，对涡减少至一对，而且沿径向充满整个盘腔；此后随离心浮升力的增加对涡的数量不再变化；r-θ面的对涡相对于盘面周向移动，但是形状基本保持不变。

在根据面板数据本身的特征选择适宜回归技术的基础上，通过研究发现，在通过家族控股上市而形成的民营上市公司中，年度内董事会会议次数对企业的市场价值有显著的正向影响，而在通过兼并重组取得控股地位的民营上市公司中，这种影响并不显著；在考虑控股股东现金流权与投票权分离程度的调节作用后发现，随着控股股东现金流权与投票权分离程度的提高，年度内董事会召开会议次数的增加有利于企业市场价值的增加。

It is proved that the problem of determining whether there is a Hamiltonian path from a specified vertex s to another t on a given digraph can be reducible at polynomial time to the problem of constructing a minimum spanning flow in a two-terminal extended network Ns,t, with the unit capacity for all arcs.

在此基础上，利用网络最小生成流的概念提出了一个修正模型，并证明了无环最小生成流问题可以在多项式时间内转换为哈密顿圈问题。文中最后指出，这一新的模型为解决在有向图内构造哈密顿轨的有效算法提供了一个新的思路和方法。

While 30μmol·〓 FRCRSFa and 10μmol·〓 E-4031 were dialysed intracellularly via the patch-pipette, FRCRSFa significantly decreased 〓 exchange current and there was no the further decrease after adding FRCRSFa in the perfused solution with the same concentration, whereas E-4031 dialysed had no effect on 〓 exchange current, but a obvious increase of it occurred when adding E-4031 to the perfused solusion with the same concentration.

分别将30μmol·〓的FRCRSFa和10μmol·〓的E-4031加入微电极内液中，FRCRSFa显著抑制了〓交换电流，当在细胞外灌流液中加入同样浓度的FRCRSFa时无进一步抑制；而胞浆内的E-4031对〓交换电流无显著作用，而在灌流液中加入同样浓度的E-4031后，却显著增强了〓交换电流。

为了探明多层住宅烟道串味的机理，采用κ-ε湍流模型，利用两相流理论，对多层住宅烟道内的流场进行数值模拟，得到烟道内的压强、速度和体积分数分布图。结果表明：在第一支烟道与主烟道的交汇处压强梯度较大，一楼排放的烟气大部分向上流动，第二支烟道附近油烟的体积分数梯度大

It shows that runoff is closely correlated with the features of individual precipitation, and it is also affected by vegetation within a short period of time. Raindrop erosion, sheet flow erosion and rill erosion on the slope are the main soil erosion patterns; sediment yield occurs mainly in flood season. Human activity and individual precipitation are two important factors that control the soil erosion at a small watershed. Comprehensive management on the slope in a small watershed is an efficient measure of water and soil conservation.

分析表明，小流域的产流方式容易随次降雨条件的变化而变化，植被因素在较小时间尺度内就会影响产流；产沙主要来源于坡面上的溅蚀、片蚀和细沟侵蚀，时间主要集中在汛期；人类活动以及次降雨条件是控制小流域侵蚀产沙的重要因素；在小流域内进行坡面的综合治理是水土保持的有效措施。

Solani. The extract was further separated into two parts and one part separated by ethyl acetate while the other was separated by petroleum ether. Based on the inhibition experiment against R. solani, ethly acetate extract has a rather strong effect on R. solani with 89.70% inhibition rate and 15.52 mgmL^(-1) EC 50.The effect of petroleum ether extract on R. solani is relatively weak. The former was again divided into five parts in silica gel column, of which the second part significantly inhibits R. solani. During the periods of 24 and 48 hrs, the inhibition rate of the second part on R. solan is respectively 89.58% and 80.36%.
