The updated theoretical model agrees well with the experimental model , which can satisfy the actual engineering application request 修正后的理论模型与试验模型符合良好,可以满足实际工程应用要求。
This paper considers typical case in the engineering and applies analogous theory to set up testing model performed in a flume 结合工程实践中的典型情况,应用相似比理论,建立起可在水槽中进行的试验模型。
It ' s possible the ship was a developmental prototype from some showroom floor , cobbled together from several different models 有可能这船不过是从展览馆弄来的一个试验模型,把几个不同的机型七拼八凑在一起的产物。
The density flows in a reservoir model are also calculated , and the calculated results are compared with others 对水库冷水人流试验模型进行了模拟,并将计算结果与已有文献进行了比较,结果表明:无论是下潜流的厚度。
