For general engineering problems, the analytical transformation rules are sufficiently accurate to design the similar cascade profile, but further improvement of the precision is limited by the one-dimensional assumption of the transformation, therefore an inverse blade design method—influence matrix method, based upon the surface vorticity model, is developed to improve the precision effectively.
进一步讨论了在具有相同表面压力系数分布的情形下,进口马赫数对附面层发展的影响,发现在一定条件下,只要表面压力系数的分布相似,则叶面附面层发展情况及无量纲气动力参数也将存在相同精度的相似,这一结论使我们在进行相似流场模拟的模型设计中,得以只进行无粘流场之间的相似变换,从而大大减少相似模型设计的工作量和复杂性。

The following results were obtained: 1. Several multi-pore materials were compared and a nylon membrane was choosed to conduct experiments. 2. Two devices and methods for controlling negative hydraulic heads were developed. Coupled with the devices, a system for precise control of soil moisture udring pot experiment was developed. 3. Two times of pot experiment studying wheat seedling growth under precise soil moisture control were conducted. Some very important results were obtained. 4. Capillary rise, horizontal and vertical infiltration under different nagative hydraulic heads were observed. The concepts of "critical wetting distance" and "wetting coefficient" were proposed. The linear relationship between wetting front movement distance and cumulative infiltration amount was confirmed. Spatial distribution model of soil moisture and its simple derivation method were established.
