Based on 3D steady and incompressible N-S equation and k-ε turbulent model, the aerodynamic performance of three different design options of 160 km/h container flat wagon was analyzed and compared using finite volume method. The three design options are as follows: the first design option has no headwall and the side surface of side beam is flat; the second and the third both have headwall and high side beam, and the side surface of side beam of the second is obtuse, while the third is cambered.

According to the theory of the coagulation method it can be classified two types, one is the measure with photoelectric and nephelometric analysis; the other is the measure with double coil and a magnetic steel ball. coagulation method is physical quantity changes below coagulant acting on blood plasma, for example light、electricity、machine movement etc, and then the data is analyzed by computer to final result, so coagulation method is also called biology-physics method. Photics'blood coagulation apparatus determines coagulation by nephelometric'changes in the coagulate process.

凝固法是通过检测血浆在凝血激活剂作用下的一系列物理量的变化，由计算机分析所得数据并将之换算成最终结果，所以也可将其称作生物物理法；光学式血凝仪是根据凝固过程中浊度的变化来测定凝血的；双磁路磁珠法其原理是利用血浆凝固过程中，在其内部运动的物体所受阻力增加，因此通过测定受阻情况可以反映血浆凝固情况；另外近些年还有很多人采用压电石英晶体法来进行血凝研究。

Through solving the nondivergent inviscid linear vorticity equation in cylindrical coordination of barotropic atmosphere with WKBJ method, the authors point out that one kind of wave, named vortex Rossby wave, which is similar to planetary wave, exists in hurricane, its formation is due to the gradient of vertical vorticity component of basic state.
