release ratio

Results: The optimal CPSP sustained-release behavior in vitro of the buffered pellets contained citric acid was independent of pH environment when the amount of coating materials was 7% of total weight and the ratio of the RS to RL was 1 ∶ 1.5;

结果：选取含有柠檬酸的缓冲型丸芯，包衣增重为7%，RL与RS质量比为1∶1·5时，体外释放呈非pH依赖型；

The study finds that market response positively to the release of the reform information, cumulative abnormal return is positive, and the extent of response is significantly positive with the ratio of presenting shares and insignificant with the proportion of non-circulate shares.

研究结果表明：市场对此反应积极，期间累计异常收益率为正，且市场反应程度与公司送股比例显著正相关，而与非流通股比例无关。

Field release test showed that the population of A.glabripennis could be suppressed with release ratio of5 ∶ 1.The major problem is artificial rearing of this species.

田间纱笼释放试验表明，释放比为5∶1可压低野生虫口数量。利用昆虫不育技术防治光肩星天牛的难点是人工饲养。

The action mechanism of back filling body and the control of back filling on rockburst's two parameters ( stress release rate and average jamb stress) are researched in the thesis. The essence of filling reducing rockburst occurrence and increasing of recovery ratio is discovered.

本文研究了充填体的作用机理和充填对岩爆的两个控制参数-应力释放率和平均矿柱应力的控制，揭示了充填减缓岩爆发生、提高矿石回采率的内在本质。

Heat release rate, average burned gas temperature and NO formation as well as turbulent burning rate, turbulent flame propagating speel and flame speed ratio in different flame zones were computed as model output.

本模型不仅可以计算出燃烧放热率，燃气平均温度，NO生成规律，还可提供各火焰区的紊流燃烧速度、紊流传播速度和火焰速比等重要参数。
