通路面积
Examples
- At the beginning of this article , we give the analysis about the principle of external condensation . we find out that the most important factor in the condensation is the temperature of the air in the system . and we point out the factors which can make influence in the external condensation , such as the temperature and the humidity of the environment , the temperature and the pressure of the supplying air , the load of the system , the area of passage of speed control valve , and so on . next , we give the mathematics model of the pneumatic system using the knowledge of aerodynamics and heat transfer theory . and using the finite difference method and the numerical analysis we can get the solutions of the model . we use c program to simulate the model
本文首先对气动系统外部结露的原理进行了分析,指出了气动系统内部气体温度下降是气动系统外部结露根本原因,提出了影响气动外部结露的主要因素,包括环境温度、环境湿度、供气压力、供气温度、气缸负载和调速阀开度等。然后应用气体动力学、气体热力学和传热学对气动系统建立数学模型,用逆步进有限差分法和数值分析算法对所建模型进行求解,利用c语言编制程序对气动系统模型进行仿真,给出了气管及气缸内气体的各个时刻的状态参数。 - Comparison of water level between measured and computation shows that the local head loss coefficient cannot give head loss by spur dike completely , and the effective area of passage is difficult to be ascertain . for this reason the two methods for water surface profile computation cannot predict the raise of water level upstream the spur dike accurately
计算结果表明，局部水头损失系数并不能完全反映出由于丁坝阻挡所带来的水头损失，而丁坝附近的有效过水面积难以准确地确定，这些导致前两种方法均不能很好地计算出丁坝上游水位的壅高值。
