A numerical calculation method to solve the cascade equation was presented.Analytical solution to the cascade equation was obtained in the case of quasi-ideal cascades,that is,the cascades with a constant partial cut at all stages.Formulas were given for the calculation of the relative product and waste flows,the total substance f...

各级组分分流比不变的多组分级联称为准理想级联，得到了计算存在损耗的准理想级联中相对产品流、相对贫料流、级联中总物质流量以及产品流和贫料流中组分丰度的解析表达式。

When normal operation the saturated transformer type SSFCL is equivalent to original transformer coupling solid state fault current limiter, but the coupling transformer coil enters deep saturation when short circuit fault occurs. After the SCR bridge withdraws from the system connection, the saturated coil reactance and the leakage reactance of coupling transformer play the role of limiting stable short-circuit current, equivalent to SSFCL with bypass inductance.

饱和变压器型固态限流器正常运行时等效于原来的变压器耦合固态限流器；但在短路限流时允许耦合变压器铁心进入深饱和；在桥路退出系统后，饱和激磁电抗和漏抗起到限制稳态短路电流的作用，等效于带旁路电感的固态限流器。

建立了缸体-配流盘，配流盘-后端盖两种配流副之间的压力场数学模型，并据此对液压变压器进行设计和校核，满足最佳配流和强度要求。

It is worth to be noted that the needed driving current to the MR valve with both annular and radial damping gaps is less than that to the MR valve with annular damping gaps under the cut-off state of the MR valves, which show that the MR valve with both annular and radial damping gaps consumes less energy.

测试结果显示：（1）在相同的工作条件下，同时具有圆环和圆盘阻尼间隙的磁流变阀产生的压降更明显；（2）处于截止状态时，同时具有圆环和圆盘阻尼间隙的磁流变阀的激励电流明显小于具有圆环阻尼间隙的磁流变阀的激励电流，因此采用同时具有圆环和圆盘阻尼间隙的磁流变阀可以节约能量的消耗。

The boundary element method has been used in this paper to calculate the potential wake fraction of the 8301 twin stern ship,the HS80 high speed passenger ship and large diameter to draft ratio FT8601 pushboat .

So instead, the team used a "Graphics Changes" stream to capture all the development changes and then "deliver"4 these changes to each variant that needed them -- in this case, the hand-held and prestige car streams

所以，团队用另外一个&图形变化&工作流来组织所有开发修改，然后交付这些修改到每个需要它们的差异性工作流---在这个例子中，即手持设备工作流和高档车工作流。
