本试验以红三叶为材料，采用盆栽试验、室内化学分析和统计分析相结合的方法，从植物营养的角度研究了土壤和施肥对红三叶产量和品质(包括饲用品质、矿质品质、保健品质)的效应。

Based on comprehensive analysis of Taiping coalmine hydrogeological condition and water outlet lithologic characteristics through contrastive analysis of borehole water prospecting drainage and water sample tested data considered that the indirect water filling source of 700 level belt inclined winze may come from Mosuo River According to mine inflow point location and water yield water rich zone in front of roadway checked out by transient electromagnetic method adopted a water control scheme of shallow g .

在综合分析太平煤矿井水文地质条件，出水点岩性特征的基础上，通过钻孔探放，水样化验资料的对比分析，认为该矿+700水平胶带暗斜井的间接充水水源可能来自摩梭河；基于涌水点位置与出水量，以及瞬变电磁法确定的巷道前方富水区域情况，确定了采用浅层注浆法封堵的治水方案。

This study focuses on flood hydrographes and water yield from the point of view of runoff generation.

对西南地区的山区、冰川—森林混合带和喀斯特等3种地貌类型的河流，从径流形成机理的角度对洪水过程与水量及其变化等特性作分析。

Yield increases to a point then decreases.

产量增加到一定值，然后下降。

Bull; Yield increases to a point then decreases.

产量增加到一定值，然后下降。

The effects of environment factors on the black point rate, yield and quality of spring wheat have certain correlations.

小麦抽穗至成熟期间低温、多雨的环境条件有利于小麦黑胚病的发生，也有利于产量的提高，但这种环境条件不利于优良品质的形成。

The Black Level at this stabilized point will yield excellent picture performance.

在这个稳定点上的黑位就会产生极佳的图像效果。

In connection with the character of Boc L-Glutamic Acid and aminoacetic acid structures, the reaction of aminoacetic acid acylated via Boc Anhydride has been studied on the condition of CH3OH in the paper. The yield of the derivatives is characterized by the melting point, the content of carboxylgroup and the product purity. The results showed that the best experiment condition is followed.

本论文以甲醇作为均相反应介质，Boc酸酐与谷氨酸为原料，在碱性条件下，以产物的熔点，羧基含量以及产物纯度作为产物质量确定的指标，最终得出N-Boc-谷氨酸的合成最优条件。

The chemical structure of the product was characterized by means of the melting point and IR. The results show that tetraethylammonium bromide which was used as a phase transfer catalyst in this reaction had optimization effect on the interfacial diffusive reaction of BTC and PNP. Higher concentration of sodium hydroxide, lower temperature and a higher dosage of BTC produced a small amount of 4-nitrophenyl chloroformate, while lower concentration of sodium hydroxide and a lower dosage of BTC made reaction incomplete, which affected the yield.

结果表明，在碳酸二（4-硝基苯基）酯合成中使用的相转移催化剂四乙基溴化铵对受界面扩散控制的BTC气与对硝基酚钠反应有良好的相转移催化效果；氢氧化钠质量分数较低时，酚钠盐向溶有BTC的油相扩散速度较小，较高时会产生氯甲酸对硝基苯酯；温度较低、BTC量较高时，会产生少量氯甲酸对硝基苯酯，BTC用量较低会使反应不完全，这些都影响着收率。

Relationships between durene modified pitch properties, such as soften point,coke yield and viscosity, and pitch fractions, especially TS fraction and PI fraction had been investigated.

考察了不同压力体系中均四甲苯改性沥青的TS组分和PI组分与沥青软化点、焦化值及粘度三种性能参数之间的相互关系。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
