A satisfactory result was obtained,the correlation coefficient of the built model based on Leave-one-out Cross-validation were 0.990 0 and 0.986 7,respectively.This model is tested by 13C NMR chemical shift of three terpenoid compounds and the excellent result with correlation coefficients R =0.977 7 was obtained.

而C原子是组成有机化合物分子骨架的重要元素，其NMR谱包含了与该分子量子化学性质直接相关的信息[2]，因此，NMR谱被广泛应用于对有机化合物结构的鉴定[3-4]、动态过程和平衡及水溶液中蛋白质三维结构的研究(见2002年诺贝尔化学奖得主维特里希的成果)。

Advocate Liang change is to use pinprick felt dip polyvinyl alcohol, be arranged through stoving and make, its so not waterproof because polyvinyl alcohol infusion is aqueous solution,be.

主踉革是采用针刺毡浸聚乙烯醇，经过烘干整理而制成，其所以不防水是因聚乙烯醇浸剂是水溶液。

After peltate yam is water washed, crushed, fermented and acid hydrolyxed, the solid matter and acid water solution are separated via centrifugation, the solid matter is extracted with organic solvent to make saponin extracted into organic phase, the organic phase is back extracted to eliminate other components, the organic solvent is distillation recovered for reuse and precipitation separated saponin is stoved to obtain product.

黄姜经水洗净、粉碎、发酵和加酸水解后，离心分离固体物和酸性水溶液，用一种有机溶剂萃取固体物，皂素被萃入有机相中，经返萃取去除其它成分后，将有机溶剂蒸馏回收，重用，沉淀析出的即为皂素，经烘干即得产品。

From the experimental results it has been observed that water was sorbed little preferentially over the entire composition range.

实验发现，交联聚乙烯醇膜在乙二醇水溶液中对水的优先吸附并不明显。

The prerequisite for the multi-reaction of heavy metal ions distributed on the mineral-water interface mainly depends on the hydrolyzation of the ad sorbates and the electric charge of the sorbent. Thus the pH value becomes a key factor affecting the reaction of mineral-water interface.

金属离子(M2+)在矿物-水溶液间分配有多种表面反应机制，这些表面反应发生作用的条件主要取决于吸附质水化学性质和矿物表面荷电性，因此，溶液pH值是影响矿物/水界面反应性的关键因素。

Under the open-field condition, it was investigated that foliage spraying potassium ferrate degraded organophosphorous pesticides in spinach.

在露地栽培条件下，研究了叶面喷施高铁酸钾水溶液对菠菜中有机磷农药的降解作用，并探讨了高铁酸钾对菠菜相关酶活、MDA含量及品质指标的影响。

The binding of simazine to catalase in aqueous solution was studied using fluorescence spectroscopy and high performance liquid chromatography with microdialysis sampling technique.

应用荧光光谱法和微透析液相色谱法研究了水溶液中除草剂西玛津与过氧化氢酶分子间的相互作用。

Sample matrix are discharged by the pre-column. The mobile phases applied consisted of 0.1% HOAc (pH3.0) acetonitrile-water on extraction column with UV detection at 225nm. Then, coupled-column liquid chromatographic methods for the direct analysis of atrazine and simazine in urine was established. As a result, the system showed good chromatographic property in the on-line analysis of atrazine and simazine in urine.

使用该系统对尿中的莠去净和西玛津残留进行了分离分析，以含有0.1%乙酸的酸性水缓冲液对加标尿液中莠去净类化合物保留在预柱上，干扰分析的大分子被排阻而无保留通过，其它干扰分子保留小而通过，再切换六通阀，以乙腈和0.1%乙酸水溶液进行梯度洗脱，进而在下一级ODS分析柱上进行分离（紫外检测225nm），两种除草剂的分离分析取得了良好的定性定量结果
