The results showed that highly significant differences were observed between the two nitrogen treatments and also among family lines in the 4 nutrient contents. Applicating nitrogen may increase the contents of CP and CF in stalk, but decrease the contents of ADF and NDF. The variance segregation of stalk nutrients of F2∶4 lines were in normal distributions and with over parent segregation in some degree. The sensitivity to nitrogen fertilization varied with maize genotypes.

The wall sheathings are screwed on cold-formed steel studs, with 12mm gypsum board on one side and 9 mm oriented strand board on another side. Both static and cyclic load tests are conducted for a same size specimen. The purpose is to find the effect on shear strength from different height-width ratio, and to get the shear resistance limit by static and cyclic loading.

In order to confirm the influence of HCV persistent infection on IRF and type I interferon, HCV replicon cell (Huh7 cell line harboring subgenomic HCV replicons) was used.

结果发现，在NDV攻击下，Replicon细胞的IRF-7 promoter活性、内源性IRF-7和IFN-α表达水平均较Huh7细胞低(IRF-7 promoter活性上调倍数：2.54 vs 4.20，P＜0.001；内源性IRF-7mRNA表达水平：0.137 vs 1.671，P＜0.001；内源性IFN-αmRNA表达水平：0.246 vs 2.207，P＜0.001)。

The last section of chapter 3 discusses the local sensitivityof the Bayes VaR when the contaminated probability ε close to zero. Consider adifferent contaminated class 〓,where Q consists ofsuch functions q that π can be regulized to be a proper probability distribution.

当〓是由定义在参数空间上的所有概率分布组成的分布类时，在没有观测数据和存在观测数据两种情况下，我们分别得到了基准先验分布〓下BayesVaR在ε污染类上对应概率水平的变化范围，该范围越小，表示基准先验分布下BayesVaR的稳健性越好，该范围越大意味着稳健性越差。

For the first time, a screw pile and pile driver system for preventing flood and rushing to deal with an emergency was manufactured. The screw piles of the system is different from screw drills used to sap, and it doesn't push soils out. Analyses, including the screw pile's structural strength analysis and the screw blade's welding analysis, were done by ANSYS, which showed that the screw pile's structural strength is enough and that the distort of the screw blade is small. Testing on the screw pile and pile driver system showed that the system performed stably and could meet the need of preventing flood and rushing to deal with an emergency. A mechanics model of interaction of a screw pile and soil was built, and expressions of torque of screw pile's cylindrical part on the condition of screw pile's crew part being driven into soil fully were gained, then the relation of the torque with screw pitch and out diameter of cylinder, which shows the torque decreases with the screw pitch increasing, and that the torque increases with the out diameter of cylinder increasing, which was according with the experiments of the screw pile's being driven into soils, and thus a screw pile with the best structure was chosen. Experiments of bionic surface showed that, on the condition of certain pressure on the surface, the protruding bionic surface can not reduce adhesion and resistance and that the corrugated bionic surface can reduce adhesion and resistance. An orthogonal experiment of the corrugated bionic surface was done with the factors including the width of protrusion, the space between two protrusions, the trolley's velocity and the vertical surface pressure and with the surface frictional coefficient as the experimental target, and some inclusions were drawn that the best combination of the factors was acquired and that the width of protrusion affected the surface frictional coefficient remarkably.

With the increased phosphorus supply, the net photosynthetic rate at saturated light, leaf area ratio, and the concentration of nitrogen and phosphorus increased in both species, and the biomass allocation of A. crenata to propagule also increased. So it was indicated that the increased phosphorus supply could facilitate the growth and reproduction of these two species.
