In order to optimize an effective combined preservative applied to the orange juice preservation, the authors studied the synergistic effect of biological and chemical combined preservative which contained Nisin, potassium sorbate, EDTA and sodium isoascorbate in preservation of orange juice compared to preservation effect of each aforementioned additive in individual use. Results show that the growth of microorganisms can not be inhibited completely using each aforementioned additive in single use.

该文以天然生物防腐剂乳酸链球菌素、化学防腐剂山梨酸钾、乙二胺四乙酸以及食品抗氧化剂异Vc钠为原料，对通过复配后得到的各组复合型防腐剂在橙汁保鲜中的协同增效作用进行研究，并且与单一的防腐剂保鲜效果进行比较，得出一组适合在橙汁中使用的高效复合型防腐剂。

The paper proposed a possible binding mode of MS-275, a benzamide histone deacetylase inhibitor, to HDAC by intensive docking study.

通过计算机模拟的对接过程研究，发现了MS-275--一种苯甲酰胺类的组蛋白去乙酰酶抑制剂与酶的可能的全新结合方式。

Although CdS and NiSe belonged to the same crystal system, they had a great difference in the morphology of products produced in ethylenediamine by a solvothermal process. By making a crytallographic comparison between CdS and NiSe, I thought that fourcoordinated crystals were more prone to grow one-dimensionally in the stacking direction of tetrahedrons. This hypothesis could also be embodied in many examples.

硫化镉和硒化镍的晶体结构都为六方晶系，但在以乙二胺为溶剂的溶剂热条件下合成出的产物形貌有很大的差别，我们通过对两类晶体结构的结晶学比较，我们认为4配位的晶体更趋向于生成一维纳米材料，并提出生长方向即为四面体堆积方向，这一假设也能得到许多例子的证实。

Methods According to the drinking water legislation in Europe threshold: 0.10mg/L NO2(superscript -, a rapid spot test method for nitrite in water was established by using an optimized composition of reagent mixture and a binary positive/negative response, conducted as follows: a tablet of a mixture of solid reagents containing sulfanilamide, N-(1-naphthyl) ethylene diamine dihydrochloride and sodium chloride was put on a spot test plate of Teflon mould, then, a drop of 30% HCl and a drop of water sample were added on the reagent material.
