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。

In the ESI+ mode the compound isolated from fraction III/9 showed a pseudo-molecular ion of m/z 261 ([M + 1]+) as well as sodium and potassium adducts with m/z 283 and m/z 299, respectively, thus suggesting a molecular mass of 260 Da.

在 ESI+模式下，从子馏分 III/9中提取出来的化合物分别出现了伪分子离子 m/z 261 ([M + 1]+)和纳钾加合物 m/z 283 and m/z 299，这样就暗示了260 Da 的分子质量。

The agriculture soils of Baimahu ,Lushan and Zoujiao are the typical cases in the suburbs of Changde. Rice soil and vegetable plot are the two typical agriculture soils, we collected 6 samples according to the scientific method in these three areas. After air dry, contuse, screen and make soil samples, we tested their 9 indexs of PH, organic-substance, total phosphorus, quick-acting phosphorus. Then analysed the fertility condition of these areas. Then apply feasible suggestion of fertilizer after putting forward science and suiting measures to local conditions etc, by Compare with the documents and materials. Absorb to Model TAS-986 atom spectrophotometer examine with flame law (air - acetylene ) terms of potassium make deep discussion especially.

白马湖，芦山乡和陬郊的耕作土壤是常德市郊区耕作土壤的典型代表，在这三个地区分别就水稻土和菜地这两个基本的土地耕作类型按科学的方法共采集了6个样品，经过风干，研碎，过筛制成土样后，测定了它们的PH，交换性酸，有机质，全磷，速效磷等9指标，从而对该地区耕作土壤肥力状况进行分析，对比文献资料，总结分析结果，针对不同地区不同的土壤状况，提出了科学施肥，因地制宜等可行性建议，尤其是对TAS—986型原子吸收分光光度计用火焰法测钾的条件作了深入的探讨。
