Calculation process of determining the optimum yield ratio can be simplified by the regression equation, which is convenient to master and use for engineers. 应用本文提出的拟合公式可以简化确定最优屈服比的计算过程,便于设计人员掌握和使用。
The suitable density for optimum yield were significantly connected with variety types, that was stem type > tight branch type > loose branch type. 不同株型类型品种的适宜密度有显著差异,主茎型>分枝紧凑型>分枝松散型,在适宜密度条件下均可达到较高产量水平;
The calculating formula of optimum yield point of cement slurry in cementing has been deduced upon fluid mechanics, which can be taken as the theoretical basis of cementing calculation in oilfield. 然后应用流体力学理论,推导出最优水泥浆动切力的计算公式,为现场注水泥作业提供了理论依据。
Lastly, use the model of Optimum Sustainable Yield to realize the environmental protection of sustainable tourism in tourism vacation belt around city of Jinan city. 第四,运用旅游开发最佳可持续产量的经济模型实现济南市环城市旅游度假带可持续旅游的环境保护。
