place 2 of gate was suggested. In this paper, factors affecting self-interference flow (SIF) of polymer melt were studied through MPI4.1. The results of simulation show that there is a strong interaction, which affects the flow process and aggregated structure of material, is present between the two streams of melt from two orifices during injection molding.

There are two streams of ore fluids moving in the fracture zone: one comes from meteoric water and extracts uranium from wall rocks flowing from top to bottom which is named uranium-loading fluid?

Through research on pressure drop of Ttype pipe mixer widely used in the industries by adopting airair, liquidliquid and airliquid systems, it is found that the pressure drop is mainly related to momentum ratio of two streams of mixture and has nothing to do with material properties;

In the horizontal anomalies wind fields of 850hPa,the north flow coming from New Siberian Islands are divided into two streams nearby the 100～140°E,50°N,on the one hand,it weaken the cold air coming from the north,on another hand,it strengthens the monsoon of low latitude after it goes southward,Taiyuan is flood during the flood seasons.

The experimental results show that the optimum mixing effect could be received when the cross-angle equals to about 75° and momentum ratio 0.5—1.0, and the length for mixing two streams perfectly is about 1.33—3.11D (diameter of reactor), which is much shorter than that needed along two different axis directions.

As the incision of these two streams started around that time,this age can thus constrain the date of offset of the streams,then the horizontal slip rate of the fault is determined to be 2.3±0.2mm/a. The fault also displaced the alluvial fans developed at the valley mouth of a gully east to Luanchaigou.

The collision of two streams of ideal incompressible fluid with the division of one stream into two flows in opposite directions along the boundary of the other is considered.

The problem of free flow past a point source is considered for two streams with different Bernoulli constants whose encounter creates a bounded region of constant pressure.

It is found that a dc discharge between two streams of tap water in air at atmospheric pressure is stable at a currentof 40≤I≤100 mA.

Intersexes were found in monthly samples collected in two streams in different regions of Germany.

The frequency of intersexuality differed considerably between the populations from the two streams.

Various influence factors of solid boundaries on discontinuuties in the gas molecular distribution function are considered and a bimodal two-stream relaxing distribution is suggested. In applying it to the heat conduction problem between two parallel plates by Maxwell transport equation we obtained a closed solution. According to the theory suggested in this paper, in the linear case, the calculated heat transfer is close to that given by existing theory. In the nonlinear case (when the temperature...

Various influence factors of solid boundaries on discontinuuties in the gas molecular distribution function are considered and a bimodal two-stream relaxing distribution is suggested. In applying it to the heat conduction problem between two parallel plates by Maxwell transport equation we obtained a closed solution. According to the theory suggested in this paper, in the linear case, the calculated heat transfer is close to that given by existing theory. In the nonlinear case (when the temperature ratio of two plates is equal to four), the difference between Willis precise numerical results and ours is less than 2.5%. This is an obvious improvement as compared with the Liu-Lees theory. Furthermore, temperature calculations demonstrate the existence of a Knudsen layer.

In this paper, a generalized dispersion relation of plasma is btained from MHD equation, taking account of the relative velocity VD between electrons and ions. The dispersion relation is analyzed approximately. The generalized dispersion relation for electromagnetic two-stream instability has been computed numerically, the results show that when the angle 9 increases, the condition for exciting the instability becomes stringent.

The classical plasma theory, two-stream instability theory and magnetic enhancement effect have been used to calculate the range and deposition power of an intense relativistic electron beam in the target matter. It is recognized that anomalous absorption is the major energy absorption mechanism for an intense relativistic electron in the target matter. With the two-stream instability and magnetic enhancement effect taken into account, experimental results can be interpreted rather well....
