As temperature increased from 40 to 70℃, ferric reduction capacity of microorganism biocoenosis from Jilin, Tianjin and Hunan paddy soil were restrained to a certain extent. Adding AQDS could increase ferric reduction rate of microorganisms biocoenosis from Jilin, Tianjin and Sichuan paddy soil significantly. In axenic culture treatment of 6 kinds of bacterial strain experiments from Sichuan and Jiangxi paddy soil, a bacterial strain was suitable to 50℃.

于40~70℃升温处理后，来源于吉林、天津和湖南水稻土微生物群落的铁还原能力受到一定程度抑制；添加AQDS可显著增加来源于吉林、天津和四川水稻土的3种微生物群落的铁还原反应速率；在6株铁还原菌的纯培养试验中发现了1株更适于在50℃下生长的菌株。

This method not only can make the silicate layers to achieve dispersion in the rubber matrix on a nanometer scale, but also can enhance the interfacial adhesion between the polymers and the inorganic layers, which suggests a new idea and a more convenient way for research and development of rubber/layered silicate nanocomposites.

该方法的特点是单体原位聚合时与橡胶大分子产生化学结合，同时实现对有机蒙脱土的插层，从而加强了有机-无机界面结合，实现了蒙脱土与橡胶之间的纳米级分散与复合，为制备性能优良的橡胶型插层纳米复合材料提供了一条新的思路。

A 3 factorial pot experiment, with 2 phosphorus levels, 3 soil water contents and 4 winter wheat cultivars was designed to compare the P efficiency, P uptake efficiency and P use efficiency of different cultivars at Olsen P 3 2 mg·kg 1 of soil, and as influenced by soil water content.

选用在土壤磷水平为 5～ 7mg P.kg- 1土的条件下筛选出来的不同磷效率的 4个冬小麦品种，采用盆栽试验研究了有效磷为 3.2 m g P.kg- 1土时的磷效率、磷吸收效率、磷利用效率及土壤水分对这些指标的影响。

Part I is soil dynamics including dynamic strength, deformation and pore pressure of soil, liquation of saturate sand, dynamic constitutive model of soil, dynamic response analysis of soil and dynamic stability analysis of soil.

包括土的动强度、动变形与动孔隙水压力，饱和砂土的振动液化，土的动力本构模型，土体的动力反应分析和土体动力稳定性的分析。

The results show that the hydraulic fracturing pressure is intimately related with tensile strength and tridimensional stress state of the soil. With the increase of tensile strength and minor principal stress, the fracturing pressure is enhanced.

土体发生水力劈裂时的劈裂压力与土的抗拉强度和土体所处的应力状态之间有着密切的关系，劈裂压力随着土的抗拉强度和小主应力的增加而增加。

On the ground of simple compression test, a damage equation which reflect structural strength change with pressure is carried out. And it discriminated from the strain types of common soft soil and structural soft soil.

通过分析计算，明确了先期固结压力和结构强度的概念；提出了结构稳定系数，较为准确地判断出土的结构强度的影响程度，为工程设计提供参考；④基于单向压缩试验，提出了结构强度随压力变化的损伤方程；区分了一般性软土与有结构强度的土的压密类型。

When the K application rate was 400 to 4 000 mg · kg^-1, the K fixation capacity of black soil and loess soil, whose hydromica contents were low or relatively low, decreased by 75-747 mg · kg^-l and 16-238 mg· kg^-1 desert soil , respectively, compared with no K application, while no change was observed in grey whose hydromica content was high.

与不施钾土壤相比，水云母含量较低的黑土和含量较丰富的塿土在外源钾加入浓度在400～4000 mg·kg^-1范围内，对外源钾的固定量分别降低了75～747 mg·kg^-1和16～238 mg·kg^-1，而水云母含量丰富的灰漠土的固钾能力无明显变化。

So he turned political, began working against feudal autocracy and struggle for democracy. Early in 1842, he wrote an article - Part political essays,"Prew assessment of the soil to check books," The censorship of books critical to expose the entire national territory Proudhon the reactionary nature of the system.

于是他转向政治，开始从事反对封建专制和争取民主的斗争。1842年初，他写了第—篇政论文章《评普鲁土的书报检查令》，通过对书报检查制度的批判，揭露整个普鲁土国家制度的反动本质。

In order to help for evaluating properties of soil in interaction more precisely, the paper applies elastic theory solution on different modulus in tension and compression for vertical load into semi-infinite elastic body. Through quoting Heaviside function, the solution of elasticity theory with different modulus in tension and compression is established founded on the solution of elasticity theory for the material incapable in tension and Mindlinsolution for equal modulus.

为使地基土在共同作用中的行为特征评价更为合理，本文应用了半空间问题竖向荷载下地基土的拉压模量不同弹性理论解，该理论解是通过引入Heaviside函数，利用不能承受拉应力材料的弹性理论解并结合拉压模量相等的经典Mindlin解而获得。

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。
