pressure former
2.For the reinforced earth bulkhead, its coefficient of earth pressure can be classified as the coefficient of self-wight stress and the coefficient of superimposed stress, the former is coefficient of active earth pressure at the top and coefficient of earth pressure at rest at the bottom of wall?s back, and the coefficient is changeable in linearity between them.
3.When the temperature of the medium is constant, the analysis of data presents that the diffusion coefficient of moisture increases with the reduction of absolute pressure and the rise of changing rate of pressure, among which the effect of the latter makes a big difference compared with that of the former.
7.It is shown that, in the presence of ion temperature gradient (ITG), the threshold value of plasma pressure gradient for the shear Alfv?n modes is well below that for ideal magnetohydrodynamic ballooning instability. It is also demonstrated in a more general sense that, without ITG, the former is identical with the latter.
10.Shao Xing county fine machinery manufacture co.,ltd.（The former Shao Xing county automobile brake factory）professionally manufacture construction machinery, air boost, vacuum booster and spring break actuator for forklift truck, automobile and tractor, air pressure or hydraulic pressure, single or double break, master or subsection cylinder, footplate, tracked assembly, and so on.
