常物性流体在带直肋的环形通道内作充分发展层流对流换热，内表面为均匀壁温（周向），轴向则呈线性变化，外表面绝热。求：截面上速度分布、温度分布-Constant physical properties of fluid in the annular channel with a straight rib for fully developed laminar flow within the convective heat transfer, uniform wall temperature of t

一维稳态导热问题，可以计算温度场，方便计算物体内部和边界的温度分布-One-dimensional steady-state heat conduction problem, we can calculate the temperature field, internal and boundary objects to facilitate calculation of the temperature distribution

按户分环流温法热分配计量无线通信源代码，用户温湿度，无线通信集中监控。-By the heat distribution points temperature circulation method measuring wireless communication source code, user temperature and humidity, wireless communication centralized monitoring.
