And application of turpentine oil in conventional pesticide and non-biocidal pesticide juvenile hormone analogs were discussed.

并对松节油在传统杀虫剂和非杀生性杀虫剂保幼激素类似物方面的研究进展进行了论述，同时还介绍国内外利用松节油合成的一些典型杀虫剂和新产品、及其一般的合成方法。

When these coefficients are quadratic functions of the porosity, specific constituent orthogonal weighting coefficients are derived from these orthogonal conditions along with a discussion about how to extend the applicable range of the constituent orthogonal weighting coefficients in the orthogonal coordinates. Based on the combination of the theory of critical porosity and the constituent model, it presents a specific example of the constituent model that includes two transforming points. The reasonability of above-mentioned theories is shown by comparison of theoretical calculations and measured data on effective elastic moduli of clean sandstone or sandstone analogs saturated with pure water.

再次，结合弹性模量组分关系方程与正交基函数理论，推导组分加权系数的正交条件；基于正交条件，提出组分加权系数为孔隙度二次多项式时正交组分加权系数的构造方法以及正交组分加权系数适用范围的拓展方法；结合临界孔隙度理论，提出一个基于两个状态分界点的组分模型实例；比较组分模型的计算结果与前人关于砂岩弹性模量的实验结果，证明了组分孔隙介质模型理论的合理性。

Quinazolinone ring was used to replace the quinoline moiety of quinoline phenoxyphenylacetic acids which have been discovered as potent AⅡ antagonists, to give a new series of antagonists, while their quinazoline analogs were obtained as isomers during the synthesis of.

前文报道了一系列喹啉苯氧基苯乙酸类非肽类血管紧张素Ⅱ受体拮抗剂，本文以喹唑啉酮代替化合物的喹啉获得化合物，在合成化合物时，同时还获得了化合物。

During these years (1997-2000) in the research area of annonaceous acetogenins 5 natural products and a number of chiral-pure analogs of annonaceous acetogenins have been synthesized using sugars as the starting materials. Their high activity and selectivity against cell line of colon tumor and a relationship between activity and configuration have been found too. In the respect of inhibitor of sialidase two new methodologies for the synthesis of chiral-pure 3-deoxy-ulosonic acid using hetero-Diels-Alder reaction or asymmetric propargylation as the key reaction were developed. On the topic of anti-leukemia marine natural product clavulactone a synthetic method based on the free radical cyclization and starting from sugar has been developed. In other title of PKC inhibited agent sphingosine a new synthetic route with SN2' as the key reaction has also been disclosed.
