The average absolute deviations are 0.14% for MnO(ranging from 14.0% to 21.8%),0.10% for ZnO(6.60% to 15.9%) and 0.17% for Fe2O3(69.2% to 71.6%) respectively by using a detecting system including a 238Pu source(1.11GBq) and a proportional counter.

To investigate the kinetic isotope effect of Ti-Mo alloy hydrides, E of the deuterides is compared with that of the protides. When x=0.03, E of deuterium desorption is larger than that of protium desorption. When x=0.13 and 0.25, E of protium desorption is larger than that of deuterium desorption.

结果显示，x=0.03时，合金氕化物E小于氘合金化物E，与钛放氢动力学同位素效应一致；x=0.13、0.25时，氕化物E大于氘化物E；x=0.50、1.00时，氕化物与氘化物的E差别不大。

The olivine-pyroxenite and pyroxenite with crystalloblastic texture and cumulate texture in Mesozoic igneous rocks from western Shandong and western Liaoning reveal that the several magmatic underplating events had taken place before the formation of Mesozoic host-rocks.

鲁西、辽西中生代火成岩中具有变晶结构和堆积结构的橄辉岩-辉石岩类包体的岩石学、矿物学、元素和同位素地球化学研究揭示了该区中生代寄主岩形成之前，曾有过多次的岩浆底侵作用发生。

As a whole, the rocks from diorite enclaves, through quartz-diorite, granodiorite to monzonitic granite, have the feature of REE slightly increasing, Eu from weakly positive transits to negative anomaly, but the diorite enclaves which has Eu negative anomaly. Besides, the Ba, Nb, Ta, P and Ti all show negative anomaly, and have positive anomalies of K and Th, simultaneously, there exists Sr positive anomaly in some rocks. Along with the increasing of the SiO〓, the P and Ti have negative anomaly, Th and K positive anomaly are obvious.

张广才岭中生代不同时期的花岗岩具有相同的Sr、Nd同位素特征，均具有高ε〓值、低，值的突出特点，ε〓值集中在-2～+4之间，〓值主要集中在0.703～0.706之间。

Taking the Late Mesozoic basic-intermediate dike swarms from this area as the main object, we have studied their Petrology, Geochemistry and Isotopic Chronology, and discussed the property of their magmatic source, tectonic setting and origin as well. The significant conclusions acquired are as follows: 1, The Late Mesozoic dike from the coastland of Fujian Province appears as clusters, intruding into the Late Mesozoic granite or volcanic rocks, and the lithologies are diabase, hornblende diabase and quartz-diorite etc, mainly diabase. The mode of their occurrence is mainly precipitous and they tend towards NE, approximately EW or NNE. The dike swarms did not suffer metamorphose or distortion, holding the stress state as the dike formed.

本论文以该地区晚中生代中–基性岩墙群为主要对象，研究了它们的岩石学、地球化学及同位素年代学等，对岩浆源区的性质、构造环境、成因等进行了讨论，获得以下重要认识： 1、福建沿海地区晚中生代中–基性岩墙成群产出，侵入到晚中生代花岗岩及火山岩中，岩性有辉绿岩、角闪辉绿岩和石英闪长岩等，以辉绿岩类为主，产状较陡，北东、近东西及北北东走向，大多未发生变质或变形，保持了岩墙形成时的应力状态。
