The study of fluid inclusions in sphalerites and associated gangue minerals (quartz, celestite, calcite and gypsum) shows that homogenization temperatures cluster around 110-150℃, with salinities of 1.6-18.0 wt% NaCl equivalent. The fluid temperature increased with the decrease in salinities during the main ore stages, and there is also a systematic westward decrease in temperature and increase in salinity in the Jinding ore district.

The calculation of the elemental mass balance interprets by elemental calculation to explains the elementary activity law: the composition of alteration rock in the central of alteration belt has the largest degree of variation, a large number of permeability fluid carry active components into the dilation space, which has significance to the further enrichment of the ore-forming element and the remobilization of correlative elements.

通过元素质量平衡计算解释了成矿过程中体系的元素行为规律：蚀变带中心蚀变岩的成分变异强度最大，大量渗透性流体携带活泼组分进进扩容带，对成矿元素进一步富集，相关元素(Ag、Cu、Zn、Hg、Pb)活化转移产生重要的影响。

It suggests that the vortex migration and crystalling phase vortex nucleation of microscale ore-forming fluid will be the another important way in which some matter in system of metallogenetic kinetics moves and exists.

这暗示，微尺度成矿流体的涡旋运移与晶相涡旋成核可能是地球成矿动力学体系中某些物质运动和存在的又一种重要的形式。

Based on theory of ore forming,the concept of mineral content density is first established.

从成矿理论出发，先提出含矿密度的概念，然后根据 3种不同类型的矿床成矿原理假设矿体含矿的连续性。

The Mineralization is referred to as all the processes of the origin, transport and precipitation of ore-forming matter.

成矿作用包括成矿物质的来源、搬运及沉淀的全过程，其中最活跃的因素为成矿流体。

The mineraliztion is later than the activity of the magmas. And the deposits are formed in early Yanshan epoch, just after the collision of the continents and the orogenesis.

综合矿床的成矿年龄和与其有空间关系的岩体的成岩年龄可以看出，成矿年龄不同程度地小于成岩年龄，表明矿床形成于燕山早期，稍滞后于造山带陆-陆碰撞和陆内造山作用。

The Re-Os is otopic study is of great importance in the determination of ore-forming ages and the establishment of an ore-forming model.

它为确定铜矿峪斑岩铜矿的成矿年龄及建立该矿床的成矿演化模式奠定了重要基础。

Uranium deposit No.337 in Xiazhuang uranium orefield has been regarden as a representative of the earliest forming, relatively high temperature and short time gap between the formation of pluton and the mineralization.

长期以来人们一直认为337铀矿床是下庄铀矿田成矿年龄最早、成矿温度相对较高、矿岩时差小的岩浆热液型铀矿床的代表。

The metallogenic process of gold placers in the studied region was controlled by 3 factors (material sources, neotectonic movement and climate).

本区砂金矿的成矿过程受物源、新构造运动和气候三个因素控制，经流水作用富集成矿，多年冻土主要起保护矿体的作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
