导致沉淀的

There are massive Uncurrent State-Owned Equity in the equity structure of China listed enterprises, which has already caused the distortion of enterprise governing structure and the advisability of resource disposition and so and. However, the major reason generating this phenomenon lies in the institutional risk existing in the China stock market set up in the period of economy transformation.

中国上市公司的股本结构中，沉淀了大量的非流通国有股权，这一现象已经引致了公司治理结构扭曲及资源配置非优化等巨大负面效应，导致这一现象的主要原因，在于经济转轨时期成立的中国证券市场所存在的制度风险。

In the expansive spaces,the sudden changes of chemical,physical and biochemical conditions lead to final destruction of the auriferous complex compounds and facilitate the precipitation and accumulation of natural gold in the shear belt.

在这些剪切带扩张空间内，由于化学的、物理的及生物化学条件发生突变，导致热液的地球化学平衡被破坏，促使自然金沉淀析出，并聚集在剪切带内构成矿床。

Combined with core-flood tests for sensitivity evaluation, petrographical analyses were made on more than 200 samples from the reservoir. The results indicate that the higher the PH of the fluids, the severe the formation dam...

采集该储层岩样品200余块，进行岩相学分析和敏感性实验表明：PH值越高，地层损害程度越大；而高PH值的工作液不仅引起粘土矿物的分散、运移，而且还导致部分矿物的溶解和新矿物的沉淀，使渗透率大幅度下降；同时，碱敏损害程度亦与盐度和流速有关。

The sample which has retrogressive phenomenon precipitates the secondary phase during re-ageing treatment subsequently, and the reprecipitation sequence is due to the grain size caused by severe plastic deformation. There is a critical grain size below which the reprecipitation sequence changes, the heterogeneous precipitation of phase at grain boundaries would suppress precipitation of metastable phases such as GP zones and η′ phase.

强变形导致回归后的合金在再时效处理时可再次沉淀析出第二相粒子，但析出相的析出顺序与强变形后合金的晶粒尺有相关，当晶粒细化到某一临界尺寸以下时，析出顺序发生改变，非均匀形核的平衡相可抑制GP区、η′亚稳相等前期粒子的析出。

Its form and intensity in different areas of the buried hills and different evolution stage are very different and has caused the change of reservoir properties, namely increasing heterogeneity: intensive and selective corrosion has caused obvoius enlargment of the pre—existing pores and increase of permeability of algal sparry dolomite located in main permeable course and dilution zone of water injection, precipitation of secondary minerals has caused the reduction of porosity and decrease of permeability in the upper part of oil pool and oil—water contact.

古潜山不同区段在油藏保存和开发期，其水—岩作用方式与强度具有明显的差异性，导致储渗性能的非均质性增强：在主渗流带中的亮晶藻屑白云岩由于受到多期强烈的选择性溶蚀作用，孔洞发育，渗透性增强；而在油藏顶部和底部油水混合带中，水—岩作用以次生矿物沉淀为主，孔隙被充填，渗透性降低。

The diffirences about the promotion mechanism of methanol to PCBs decomposition are found between SCWO and SCWT. The dechlorination reaction was accelerated due to the decrease of HCl which produced in the dechlorination process by the neutralisation of HCl with alkali catalyst.

发现在超临界水氧化与超临界水裂解条件下CH3OH对PCBs降解反应的促进机制有所不同，碱催化剂通过中和反应过程中产生的HCl生成NaCl沉淀导致体系中Cl的含量降低，从而促进脱氯反应的进行。

The results show that CODCr and BOD5 can be decontaminated efficiently in daily level,the ability of treating total phosphorus and total nitrogen descends in abnormal period and the unstable running of sediment pool contributes to the instability...

结果表明：此污水处理系统在运行效果下降期间，对日常用水变化量范围内的CODCr和BOD5能够起到相对稳定的净化作用；对TP和TN去除能力较差；沉淀池运行不稳是导致整个系统处理能力下降的主要原因。

In SDS-CaCl_2 system, the adsorption of Ca~(2+) ions on micellar surface can not result in the charge neutralization and there is no hydroxide group bridging effect in this system, so the surfaetant can not be flocculated in form of micelles.

在SDS-CaCl_2体系中，Ca~(2+)的吸附作用并未导致胶束表面电荷的中和，也不存在羟基架桥的作用，故该体系中的表面活性剂不能以胶束形式沉淀。

The main reasons were that the algae and organism in the water decreased the ability of removing pollutants by coagulations, the algae which grown again in the open sedimentation tank weakened the removal effect of algae by coagulation; because of the accumulation of algae and algae toxin in the filtration tank, the concentration of algae toxin in the effluent increased; by the function of fluid chlorine, the algae and organisms after the filtration will release microalgae toxin and produce a lot of byproduct such as microalgae toxin, sobomyl and so on, meanwhile, the chlorination produce considerable halide and halo-acetic acid and other disinfection byproduct.

主要表现在藻类和溶解性有机物的存在降低了混凝去除污染物的能力；藻类在露天平流沉淀池中再生长，抵消了混凝除藻效果；藻类和藻毒素在滤池中积累，导致滤后藻毒素升高；穿透滤池的藻类和有机物在液氯作用下，释放微囊藻毒素、土臭素和二甲基异冰片等胞内物质，同时生成数量可观的卤代烃和卤乙酸等消毒副产物。

The δ〓O for both of them are changed due to water/rock interaction at water/rock weight ratios of larger than 0.1, and the calculation indicates that, in this case, the influence of water/rock interaction on the δD value of the fluid is minor. In the upper part of the geothermal system, the upward ore forming fluid mixes with low temperature groundwater with very low salinity and δ〓O, which may cause the precipitation of metals.

根据氢、氧同位素研究结果，嵩溪银锑矿床的上升成矿流体是由岩浆热液与循环地下水热液混合而成，这种混合成因含矿热液上升到地热系统上部与低矿化度、低δ〓O的低温地下水发生了不均匀混合，这种混合作用导致金属矿物沉淀，但成矿物质是由上升成矿流体带来的。

In this paper, the requirement analysis, design and implementation of the system are introduced in detail.

此论文详细介绍了系统的需求分析，系统设计和具体实现。

In the context of economic globalization is increasingly deepening, China's economy can not be spared.

在经济全球化日益加深的背景下，中国经济不可能做到独善其身。
