The results of numerical simulation reveal that the resistance to liquefaction of sands increases as the angularity of particles increased, and the micro_mechanism is related to the average coordination number of sample. It also found that the numerical sand sample made from randomly mixing multiple shapes of sand can quantitatively reflect the regularity of fabric evolution of sands during liquefaction.

结果表明，颗粒棱角度越大，试样抗液化能力越强，其在细观机理上与初始平均接触数大小有关；随机混合仿真试样可以从定性角度反映实际砂土振动液化过程中的细观组构演化规律，为今后进一步的定量研究奠定了基础。

Effect of Cu, Mo and Si fertilizers on balsam pear yield and quality were studied in two different textural soils.

Based on the framework of critical state soil mechanics,a new bounding surface constitutive model for sand, being applicable to cyclic loading, is proposed.

基于临界状态土力学框架，建立了一个适用于往返循环荷载作用的砂土边界面本构模型。

Based on the experiment of sand and clay,the computing method of buoyance without seepage is analyzed.

The design of the groundwater control system was verified in a centrifuge slope test and satisfactory results were obtained.

通过一个地下水上升的砂土边坡离心模型试验，成功应用了该套地下水模拟控制系统。

It was shown that the state-dependent critical state model was capable of simulating the effect of the initial state on strain localization, especially the effect of the initial effective confining pressure on the inclination angle of shear bands.

分析结果表明：基于材料状态相关的砂土临界状态模型能够合理地描述材料初始状态对砂土变形局部化的影响，尤其是初始有效围压对剪破角的影响。

The major advantage of PFC2D is the evolution regularity of microscopic fabric parameters including co-ordination number, contact normal, normal contact force, shear contact force, can be achieved together with the macroscopic liquefaction response. The micromechanism of sand liquefaction is further discussed.

颗粒流数值模拟的优点在于得到试样液化宏观力学表现的同时，通过不同循环加荷时刻试样内细观组构参量（包括配位数、接触法向分布、粒间法向接触力、粒间切向接触力）的演化规律，分析砂土液化过程中细观组构变化与宏观力学响应之间的内在联系，从而可进一步探讨砂土液化的细观力学机制。

The process of sand absorption is:(1) the vibration head vibrates and losses the sand layer, and supply high pressure air into the sand absorption head;(2) the high pressure air generates negative pressure in the sand absorption pipe when it is discharged out from the sand absorption;(3) the sand absorption head and the vibration are shifted downwards and maintains the water flow straightly.

取砂土的过程为：(1)振动头振动松散砂土层，同时向吸砂头供入高压空气；(2)高压空气通过吸砂头从排砂管向上排出的过程中，在吸砂管内产生负压，吸砂管将管口处的水和砂土吸入到吸砂头内，在高压气流作用下，吸砂头内的砂、水和气混合而成的三相流通过排砂管排出到受砂船上；(3)在吸砂的过程中，适时地将吸砂头和振动头下移并保持钻孔套管中的水流畅通。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
