And contented similarity criterion is different between different flow patterns.
且不同流态下满足的相似准则不相同。
In free flow pattern and submerged flow pattern, as long as flow movement meet the dynamic similar criterion can reach the similarity of spillway tunnel flow pattern;
在自由流和淹没流时，只要水流运动满足动力相似准则就可达到泄洪洞水流流态的相似；
In free flow pattern and submerged flow pattern, as long as flow movement meet the dynamic similar criterion can reach the similarity of spillway tunnel flow pattern;
