In this paper, A method of modern instrument analysis-mass spectremetric isotope dilution has been used for the determinations of REE in the samples of cenozoic alkali basalts and their ultramafic inclusions and megacryst minerals from Kuandian, Liaoning Provence, and Penglai, Shandong Provence. The diagrams of normalized REE patterns, calculated and plotted using Nakamura's chondrite values, show that the REE abundances and patterns of the Samples from Penglai are very similar to those from Kuandian.

In this paper, A method of modern instrument analysis-mass spectremetric isotope dilution has been used for the determinations of REE in the samples of cenozoic alkali basalts and their ultramafic inclusions and megacryst minerals from Kuandian, Liaoning Provence, and Penglai, Shandong Provence. The diagrams of normalized REE patterns, calculated and plotted using Nakamura's chondrite values, show that the REE abundances and patterns of the Samples from Penglai are very similar to those from Kuandian. This uniformity arises from similar geologic structures and physico-chemical condi-tioiis of melting and fractional crystallization processes of these two areas. On the basis of REE patterns the spinel Iherzolites and the eclogites in the two areas have been considered as ultramafic inclusions of primary phases and residual phases respectively. The pyropes as megacryst may be earlier products from liquidus and the later metam-orphism has not led to redistribution of REE. The crystallization of the Al-rich augites may have occured later than that of the pyropes.

本文应用现代仪器分析方法——质谱同位素稀释法测定了辽宁宽甸和山东蓬莱碱性玄武岩及其深源超镁铁岩包体和巨晶矿物中的稀土元素REE,测定结果用Nakamura数值进行了球粒陨石标准化计算。根据所得REE丰度和分布模式特征,推测了两地区的尖晶石二辉橄榄岩属残渣型地幔岩包体,榴辉岩属原始型地幔岩包体。两地区的镁铝榴石巨晶可能是早期液相线上的产物,后期的变质作用对整个REE没有明显的影响。富铝普通辉石巨晶则是比镁铝榴石较晚期的结晶产物。两地区的碱性玄武岩及其超镁陕岩包体和巨晶矿物在REE丰度和分布模式上十分相似,表明了两地区所处的大地地质构造以及熔融和分异作用的物理化学条件的相似性。

The method on group of derivative,ultraviolet absoption spectra lines was used to determined for forty species of Chinese materia medica in four species of solvent.Their diagrams on group of first order dervative ultraviolet species of solvent,and their characteristic and reappearance and sensitivity are all better than the old method.This method is rapid and accurate,and data were directly perceived through the senses.The first order derivative ultraviolet spectrograms have been determined for some Chinese mataria medica are similar in gene.A method of modernized instrument analyse of highly sensitivity and high- speed and handy for identification of Chinese materia mediea was provided.

在中药鉴別紫外谱线组法基础上对几十种中药进行了导数紫外光谱谱线组法测试研究,发现其四溶剂一阶导数谱线各异,且具有较好的特征性、重现性和较高灵敏性,直接读数,准确、快速、直观。据此首次提出鉴别中药的导数紫外光谱谱线组法,提高了鉴别中药的可靠性和方法本身的选择性,并且用该法对部分不同产地基原相近及常用中药材进行了测试鉴别,取得了满意效果,为中药鉴別工作提供了一种高灵敏性、快速、简便的现代仪器分析方法

The metabolism of Herbicide 83-1 was studied in rats in vivo. After oral administration of the herbicide, four ultimate metaholites were isolated and identified from urine by means of HPLC, UV, IR and MS. It was found that the metabolic reactions of the herbicide in rats were reduction and conjugation. The metabolic pathway of the herbicide in rats was deduced.

目前,我国对新农药的登记要求对其进行代谢降解研究。为此本文采用HPLC、UV、IR和MS等现代仪器分析的方法,给大鼠经口染毒83—1除草剂后,在大鼠尿中分离和鉴定出四种代谢代物,发现该除草剂在大鼠体内的代谢主要是还原和结合作用。从而推断了该农药在大鼠体内的代谢转化过程。
