Ways to Replace Guide Axle in Belt Conveyor with Wire Rope;

Effect of axial heat conduction on heat transfer in micro-channels;

With the further simplified conditions, the effect of an axial heat conduction on heat transfer to liquid sodium in thermal entrance region .

The axial distribution of the film thickness and meniscus of liquid, the axial profile of the pressures of liquid and vapor and the capillary radius of the liquidvapor interface, the frictional interaction at the liquidvapor interface and the axial heat conduction of the wall .

The netrins play a critical role in cell migration and axon guidance.

By regulating the microtubule dynamics and promoting the clustering between microtubules, MAP1B exerts several significant effects on axon guidance, axonal pro.

Cytoplasmic Ca~_(2+) elevation and changes in Rho GTPase activity are both known to mediate axon guidance by extracellular factors, but the causal relationship between these two events has been unclear.

The new device has the following advantages: (1) improving the working conditions of the displacement transfer rod and increasing the observation accuracy because the guide bearing that decreases the fric.

In order to resolve the problems of plastic formation and accuracy control of blank,the warm cold compound forming process(preliminary shaping-backward extrusion forming-cold extrusion sizing) and the forming theory of "guiding flow in axial direction ","push extrusion forming " were adopted based on the study on the theory and experiment and the corresponding dies were developed.

The precision plastic forming theory of warm cold compound forming that formation of geometric shape is guaranteed by warm forming and accuracy by cold forming,and the forming methods of‘guiding flow in axial direction’,‘push extrusion forming’,‘control the deformation gradually’, ar.
