The calculation on the 3-D flow field, temperature field and blowout characteristic of the combustor for the ground idling, the peak, the middling, the peak head load, and the altitude-small lever flying conditions adopts the modified-two-equation turbulence combustion model. 采用修正的k-ε双方程紊流模型计算了燃烧室在慢车、最大、中间、最大热负荷和高空小平飞下的三维流场、温度场和熄火特性。
The quintuple strong motion seismograph may record three-component ground displacements with mechanical lever amplification, visible recording and triggering without the loss of the first motion of the earthquake waves, preserving wave forms 20 seconds before triggering. 五倍强震仪是记录三分向地动位移的仪器,直接机械杠杆放大,可见记录,触发但不丢地震初动,能保留触发前20秒内的波形。
Analyzing the moisture content balance with the rate of forest coverage increase in straight ground water lever fall. Around 29.9% of the rate of forest coverage environment factor stay best stage. 从水分平衡分析得出,森林覆被率高出一定值时,地下水位下降,在森林覆被率为29.9%左右时,环境因子处于最佳阶段。
Moreover, considering the existing of the ground water, the author treat the soil layer below the water lever as the saturated one and the soil layer above the water level as single-phased elastic one. 此外,实际工程中,由于地下水的存在,地下水位以下的土可视为饱和土,而地下水位以上的土层可视为理想的单相弹性层。
