随铝含量增加单相奥氏体区变小变无,液化温度降低,热加工性能恶化。
Then the Lagrange particle track model and the uniphase coupling method are used to simulate the gas-solid two phase flow field in the centrifugal fan.再采用拉格朗同颗粒轨道模型,利用单相耦合法模拟了风机内部的气固两相流场。
The JDS uniphase HA9 PThe JDS uniphase HA9 Programmable Attenuator is a highresolution, extended-range, programmable attenuator ideal for testing power meters and for general test and laboratory work.描述:HA9可编程衰减器是一种高分辨率,扩展范围,功率计和测试一般测试和实验室工作的可编程衰减器的理想选择。
