通过前期试验发现乙醇和异丙醇的分离较难，所以运用正交实验设计法，确定最佳操作参数，获取优化的分离度。

Because ethanol and isopropyl alcohol is difficult to separate, the orthogonal experiment design is used to define the best operation parameter and to obtain the optimization resolution.

运用正交实验法研究了不同双钝体组合对斯特劳哈尔数影响，得出通过选择适当的钝体及钝体组合，通过试验可以设计出满足要求的涡街流量计的结论。

At the same time, the experimental results show that the method of the isolate elasticity has little effect on the anti-jamming performance of the dual bluff body vortex flowmeter.
