根据各物质的环境暴露浓度和相应急性毒性值的累计概率分布曲线估计了各物质相对风险性的大小。
The relative risk of these chemicals was also investigated based on cumulative probability distribution curves, which were generated based on both exposure and acute toxicity data.
计算结果表明，这些模糊控制值与相应工况的优化设计值的相对误差除两个工况外均小于5 %。
The results show that the relative errors between the fuzzy control values and the corresponding optimized design values are less than 5% except two engine work status.
在相对误差意义下定义了针对一种简单的顺序滤波器的两种相对误差准则，并在该准则基础上得到了相应的最佳估值。
Two relative error criteria for simple order statistic filters (Ranked-order statistic filters) are defined, and optimum estimation based on the error criteria is obtained.
当相对劳动生产率、贸易条件、开放度以及实际货币供给超过各自相应临界值时，这些经济要素变量对汇率的影响会下降很多甚至不再影响汇率；
Once the economic variables transcend their corresponding threshold, their impact on exchange rate will decline a lot, what's more, maybe the impact will diminish.
