As shown in the experimental results: as the conductor of petroleum biological degradation, the quantity of microorganism is the important factor of petroleum degradation efficiency, the huge natural capacity of microorganism in soil is its foundation of bioremediation; petroleum density in certain scope do not affect for the degradation efficiency of petroleum, and in the density of 5%, its initial degradation efficiency is higher, however after training 40 days, this kind of advantage change weak gradually, the reason may be the petroleum of high density probably having certain poison role for microorganism; the best ecological condition of petroleum contaminated soil bioremediation is that nutrition material C: N = 60, electron receives body HiOi joining quantity amount to 12 mg/g, water content is 50%, surface activator is anion surface activator of 12 Wan base benzene sulphur sour sodium; the relation of primary and secondary of factor is water content, surface activator, nutrition material and electron receiver.

试验研究结果表明：作为石油生物降解的执行者，微生物的数量是影响石油降解效率的重要因素，土壤中微生物的巨大的自然容量是其生物修复的基础；石油浓度在一定范围内对石油的降解效率并没有影响，并且在5％浓度时，其起始降解效率较高，但是到了培养40天以后，这种优势渐渐变弱，可能还是高浓度的石油对微生物有一定的毒害作用；石油污染土壤生物修复的最佳生态条件为：营养物质C：N为60，电子受体H_2O_2的累计加入量为12mg/g，含水量为50％，表面活性剂为阴离子表面活性剂十二烷基苯磺酸钠；因素的主次关系为：含水量、表面活性剂、营养物质和电子受体。

This type of cracking most often occurs on surfaces that are both prone to corrosion and exposed to sustained tensile stresses while in service, such as the lower surface of landing gear trucks, axles, and the surfaces of forward and aft trunnions.

这种裂纹大多出现在表面，主要是在使用中受腐蚀和持续张力的共同作用，如起落架支柱的下表面、轴和前后枢轴的表面。

To examine the effect of surfactant adsorption on physical stability of flowable concentrates used for coating seeds with pesticides, high performance liquid chromatography was used to analyze the adsorption of a surfactant (the nonylphenol ether, Witconol NP-100) on thiram and carbofuran particles.

采用高效液相色谱仪研究了水悬浮液中烷基酚聚氧乙烯醚(Witconol NP-100)在福美双和克百威两种农药颗粒表面的吸附性能，并探讨了表面活性剂在农药颗粒表面的吸附对悬浮种衣剂的物理稳定性的影响。

Thiols, serving as low surface energy materials, can be adsorbed on the surface of ZnO, and the adsorption layer become denser and stronger with the increasing of carbon chain in thiols.

表面能较低的硫醇分子可以吸附在ZnO表面，并且随看硫醇分子中碳链的增长，其在ZnO表面形成的吸附层越致密牢固。

The oxide layer is predominantly TiO2, which contains a small amount of suboxides TiO and Ti2O3 between the outmost layer and metallic substrate. The XPS analysis confirms that Al2O3 is located mainly in the outer surface of the modified layers, in which vanadium and vanadium oxide are not detected.

结果表明：随着注入离子能量的增加， Ti6Al4V合金表面改性层的深度明显增加，改性层的外层由一定厚度的TiO2组成，外层与内层基体之间存在Ti2O3和TiO； Al元素在改性层的外层以氧化物形式存在，且该氧化物趋于表面生长；在表面改性层的外层未发现V及其氧化物。

Through field investigation on soils of different tillage ways and soils with different kinds of stubbles,the results indicated that,the effect of anthropogenic factors on wind erosion is great,and wind erosion of grasslands, soils with stubbles and ploughed farmlands was obvious different.

留茬地因为表面残茬的存在显著增加了土壤表面粗糙度，从而使得其风蚀强度较小；而秋翻地人为扰动较大，表面覆盖度较小，其风蚀强度在所研究的土壤中为最大。

The formation of the striations was affected by the combination effect with the distribution of spatial potential and surface charge on the anode surface, especially the distribution of electron charge on the anode surface would greatly influence the structure of striations.

条纹现象的形成是由阳极表面附近的空间电势分布和表面电荷分布共同作用产生的，特别是表面的电子电荷分布对条纹现象的影响很大。

Surfactant sorbed on soil increases the adsorption capacity of the soil; however, the microemulsion composed of surfactant and organic materials decreases the adsorption capacity of the soil.

增加离子强度对非离子表面活性剂的吸附无影响，却可略微增加阴离子表面活性剂的吸附。表面活性剂吸附于土壤后对憎水性污染物在土壤/水间的分配行为产生显著作用。

The prerequisite for the multi-reaction of heavy metal ions distributed on the mineral-water interface mainly depends on the hydrolyzation of the ad sorbates and the electric charge of the sorbent. Thus the pH value becomes a key factor affecting the reaction of mineral-water interface.

金属离子(M2+)在矿物-水溶液间分配有多种表面反应机制，这些表面反应发生作用的条件主要取决于吸附质水化学性质和矿物表面荷电性，因此，溶液pH值是影响矿物/水界面反应性的关键因素。
