We use unilateral normal distribution of upper magnitude limit instead of fixed one and analyze the results of seismic hazard analysis of this change and engineer meaning of it .

用震级 上限 的 单边正态分布模型代替固定的震级上限模型，分析了这种改进对地震危险性分析结果的影响及其工程意义。

Third it is the unilateral environmental measures that are taken to limit international trade .

最后， 环保例外 权以 限制贸易的 单边环境措施为手段。

Using high performance liquid chromatography to make quantitative analysis on 40 Hyp pure soy sauces calculated according to the normal distribution 99 % of its normal range of unilateral upper limit was equal to 2.1 mg / g of ammonia nitrogen .

本文采用高效液相色谱法对40个纯酿造酱油中的羟脯氨酸进行定量分析，按正态分布法计算其 单侧99%正常值范围 上限相对羟脯氨酸含量为2.1mg／g氨态氮。
