During the course of acid rain eluviation, Zn shows the most activation.

酸雨淋滤过程中重金属元素的活动特性一方面可能取决于土壤整体缓冲酸雨的能力，另一方面更主要的可能与其在土壤中的存在形式有关。

In china stock market, the financial falsity of list company has become a focus problem .

提要：在我国股票市场中，上市公司的财务虚假已成为了制约我国股票市场稳定运行和规范的一个难点和焦点问题，但至今为止的有关研究中存在着如下的不足。

The theory that supports the existence and development of the science of forensic identification is of great importance.

司法鉴定的基本理论即支持司法鉴定存在与发展的内在要求，是司法鉴定最基础的内容，而与司法鉴定有关的其他理论和价值都是建立在这一基础之上的。

It was pointed out that even if for〓,the existence of〓solutions ofthe linear iterative functional equation〓is a difficult and veryinteresting problem.

有关文献指出，当〓时，即使是线性型的迭代函数方程〓的〓解的存在性也是一个困难而很有意思的问题。

It was so concluded that silkworm hemopoietic organs were related to the formation of hemolymph proteins, and due to the decrease of hemocytes caused by functional disruption of hemopoietic organs, synthesis of protein in fat body was affected and protein components in hemolymph changed.

由此认为家蚕幼虫造血器官与血淋巴中的蛋白质成分有关，造血器官的机能障碍、血球的数量减少可影响脂肪体中蛋白质的合成，从而使存在于血淋巴中的蛋白质成分发生变化。

Among the more and more intensive researches on NO transfer, a controversial issue regarding the mechanism is whether the NO group transfer from S -nitroso compounds occurs in a direct nucleophilic way where NO serves as the target or in a multi-step sequence initialed by homolysis of the S -NO bond.

NO转移反应的模拟研究日渐活跃。有关S-亚硝基化合物转移NO的机理存在两种争论，即以NO为靶心的直接亲核进攻还是由S-NO键均裂引发的多步过程。

The relative molar concentration ratios of c(superscript * subscript NO)/c(superscript * subscript NO2) changes as the temperature and pressure change. These results reveal that the two competitive reactions of C-NO2 homolysis (to form NO2) and isomerization may occur during the fast thermolysis of DNTF. NO formation from the cracking of furazan or furoxan rings may be limited by pressure.

结果表明，DNTF快速热裂解的主要产物CO、CO2、NO和NO2的相对摩尔浓度c与温度和压强有关，通过分析相对摩尔浓度比c(上标*下标 NO/c(上标*下标 NO2)随温度和压强的变化，揭示了DNTF中碳硝基C-NO2存在均裂生成NO2和异构化生成NO两条竞争分解的可能途径，同时压强可能抑制呋咱环和氧化呋咱环生成NO的可能性。

The existence of surface electronic states is an intrinsic property of the surface and many properties and processes happening on the surface of the materials are closely related to the surface states and their energy distribution and space distribution.

表面电子态的存在是表面固有的性质，材料的许多性质和发生在表面的过程都与表面态及其能量分布，空间分布有关。

It was pointed out that even if for m ≥ 3, the existence of C~m solutions of the linear iterative functional equation F -= 0 is a difficult and very interesting problem.

有关文献指出，当m≥3时，即使是线性型的迭代函数方程F-∑_(k=1)~nλ_kf~k=0的C~m解的存在性也是一个困难而很有意思的问题。

The results show that when the depth gradually reduces, pH values gradually increase, but conductivities and (superscript – subscript 3) content gradually reduce. There are also obvious differences between the groundwater in loess, alluvial deposit and acidity rock in the south of Chang'an, which relates to the depth, the characters of loess, the lixiviation and the evaporation. The element content of groundwater is high in the loess tableland, so it's fitter for drinking than the groundwater in the Cuihua mountains, which is of acidity and low element content.

结果表明，长安南部黄土塬随着层位的降低，pH值有逐渐增大趋势，电导率和HCO(上标–下标 3)含量有逐渐减少的趋势；黄土地下水、冲积层地下水和酸性岩石地下水的化学成分存在明显差异，这与其理深、地层性质、溶滤与蒸发作用不同有关；长安南部少陵源黄土地下水元素含量较高，比呈酸性、元素含量低的翠华山泉水更适于饮用。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
