实验证实，呫吨类化合物在自然条件下能在发挥光敏生物活性的同时迅速降解为小分子化合物，残留量少，同时，其降解中间产物和终产物的光敏生物活性也迅速降低，对环境的潜在风险很小。5。

During the magmas ascendedand intruded, the high-energy, quick ascending primary mantle magmas with xenolith andhigh-pressure megacrysts didn't react with the crustal matter, which formed products, such ascone sheets.

在岩浆上升侵位的过程中，能量高的快速上升的含有岩石包体和高压巨晶的幔源原生岩浆没有与地壳物质发生作用，其形成的产物如锥状岩席；在此之后，岩浆能量、上升速度的降低促使原生岩浆与围岩发生轻微的同化混染作用，其产物如火山熔岩和火山颈。

The possible pathway of ABAS degraded by Zoogloea HP3 was that ABAS was first cleaved to produce o-phthalic acid and products. The former was further degraded and the composites of the latter were 2-amino-3-hydroxyl-5bromobenzenic sulfonic sodium and 2, 3-dihydroxyl-5-bromobenzenic sulfonic sodium.

动胶菌HP3作用下溴胺酸可能的降解途径为蒽醌环开裂生成中间产物邻苯二甲酸，邻苯二甲酸被进一步降解；溴胺酸降解后的最终产物为2-氨基-3-羟基-5-溴苯磺酸钠和2，3-二羟基-5-溴苯磺酸钠。

Thecompositions of raw material and products were identified with GC-MS, the results indicatedthat the products were composed of (β-acryloxyl ethyl) esters of dihydropimaric acid anddehydrogenated abietic acid, and their relative amounts was consistent with the amount ofdihydropimaric acid and dehydrogenated abietic acid in the disproportionated rosin.

论文还采用GC-MS对原料和产物的组分进行了鉴别，结果表明酯化产物由二氢海松酸酯和脱氢枞酸酯组成，且其相对含量与歧化松香中二氢海松酸和脱氢枞酸组成基本一致。

Therefore,K. pneumoniae CICC 10011 is a potential strain for 2,3-BD production.Thirdly,a novel aqueous two-phase system for the recovery of 2,3-BD from fermentation broth was developed employing isopropanol/(NH_4)_2SO_4 system.The results showed that most of target products(2,3-BD and acetoin) can be partitioned efficiently into the top phase,while most of glucose can be partitioned into the bottom phase.

通过对批式流加发酵过程中两株克雷伯氏菌代谢流量的分析表明，K.pneumoniaeCICC 10011代谢产生的各种有机酸和乙醇浓度均明显低于K.pneumoniae DSM 2026，而目标产物浓度以及产物转化率却相对较高，是发酵2，3-丁二醇的优良菌株。

By using GC/MS, the process of oxidizing reaction of atractylone is studied, and five decomposition products are obtained, which is greatly different from the references-only two decomposition products, and the mechanism of oxidizing reaction of atractylone is investigated. The hypothesized mechanism of reaction is: atractylone is readily to additively react with water and to generate the semiacetalhydroxyl at 1, 4-site.

利用GC/Ms法跟踪分析了苍术酮纯品的分解过程，得到5种分解产物―与文献报道的苍术酮转变成2种产物存在较大的差异；研究了苍术酮的氧化反应机理：苍术酮与水易进行1，4加成反应，生成半羧醛羟基。

ABSTRACT The thesis aims at the studies on the total synthesis of α-alkylidene -β-hydroxy-γ-butyrolactones. It consists of the following three parts: Part Ⅰ: Review: Some studies on the total the synthesis of α-methylene-γ-butyrolactones, polysubstitution-γ-butyrolactones and α-alkylidene-β-hydroxy-γ-butyrolactones, were reviewed.

本论文以α-亚烷基-β-羟基-γ-丁内酯类天然产物的全合成研究为主，包括三个部分：第一部分：文献综述：着重介绍了α-亚甲基-γ-丁内酯萜类，多取代-γ-丁内酯类和α-亚烷基-β-羟基-γ-丁内酯类天然产物的全合成研究工作。

The fitting culture conditions for isolate BC4 producing more toxin were Improvement Fries and Czapek-Doxbiotion culture medium , culture time for thirty-five days, pH for 6, culture temperature for 25 , still cultivation, and that the juice of tomato and pepper cannot improve herbicidal activity on Amaranthus retroflexus.

试验确定了菌株BC4代谢产物中除草活性物质产生的适宜条件：即改良Fries培养基和查氏-道氏培养基：培养时间是35d；pH值为6；培养温度为25℃；静止培养；培养基中添加一定比例的番茄、辣椒的浸出汁并未提高灰葡萄孢代谢产物的除草活性。

The synthetic progress of polysuccinimide using maleic acid as original material was studied by two steps of aminization and polymerization. Changes of reactant and product composition in aminization reaction step was studied by using bromine value analysis method. It was found that amine salt and amide were main products in this step.
