By theory analyzing and example calculation and comparison, the conclusion is obtained that the traditional inferential method can be applied in the design flood peak flow calculation, yet it cannot truly express the runoff process of the rain drainage inlet, the instantaneous unit hydrograph depending on the real and actual datum is different to be used in the runoff discharge hydrograph calculation, and the no linearity reservoir means and the isochronal method have some physics base and its parameters easily evaluated and its runoff discharge hydrograph still more is close to practice.

最后，将改性前后的中空纤维膜分别应用于油水(自配浓度为60mg/L)分离试验，测定膜通量的衰减，数据表明改性后的PVDF中空纤维膜表面的抗污染能力有很大程度的提高，这说明用表面化学接枝改性的方法可以改善疏水的PVDF膜表面，该方法是切实可行的。

The finite element model included two types of main element: beam element for concrete and truss element for internal unbonded or external tendon. The end nodes of main elements were connected with internal constraints named MPC in ABAQUS. Spring elements with very large stiffness were set up at the place of the deviators of externally prestressed beams, or along the span with relatively little space of unbonded internally prestressed beams. The modified Riks method is utilized to trace the entire structural response of beams prestressed with unbonded tendon from zero to ultimate loads. The reliability of the analysis model is verified by analytical results of typical test beams in comparison with experimental ones.

该有限元模型由两类主单元组成，即混凝土梁单元和体内无粘结或体外预应力筋桁架单元；主单元的端部节点用ABAQUS的内在约束MPC连接；在体外预应力梁的转向块处，或沿体内无粘结预应力梁全跨并以比较小的间隔设置刚度足够大的弹簧单元。

The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species (r=0.93, p.01). Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher P T and lower WUE in comparison with other desert species. The unique biomass allocation of low root/aboveground biomass ratio, higher leaf area ratio, higher leaf mass per unit leaf area, and photosynthetic traits are involved in the physiological mechanisms that contributed to the rapid growth of desert spring ephemerals.

这些结果表明，所观测的早春短命植物具有典型的C3植物特征，相比其它类型的荒漠植物具有较高的单位叶面积P高T及低WUE，并且在生长发育过程中表现出很低的根／地上生物量比、较高的叶面积比和单位叶面积干重，说明它们具有相对高的生长速率，这与其生长发育节律相一致，反映了它们与准噶尔荒漠环境相适应的特点。

The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species （ r = 0.93, p 〈 0.01）. Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher Pn, Tr and lower WUE in comparison with other desert species. The unique biomass allocation of low root/aboveground biomass ratio, higher leaf area ratio, higher leaf mass per unit leaf area, and photosynthetic traits are involved in the physiological mechanisms that contributed to the rapid growth of desert spring ephemerals.

这些结果表明，所观测的早春短命植物具有典型的G植物特征，相比其它类型的荒漠植物具有较高的单位叶面积Pn、高Tr及低WUE，并且在生长发育过程中表现出很低的根／地上生物量比、较高的叶面积比和单位叶面积干重，说明它们具有相对高的生长速率，这与其生长发育节律相一致，反映了它们与准噶尔荒漠环境相适应的特点。

In comparison with the Nikon D3 and D700, maybe it is a little more noisy, but I don't see an huge difference;keep in mind that I did not have the possibility to make a side by side comparision and it was forbidden to keep the files, so I can't evaluate the RAWs (anyway, CS3 don't open 5D2 RAWs) and these are just "estimates".

与nikon的D3和D700相比，也许无敌兔有更小的噪声，但我看不出很大差别；记住我没可能做放在一起的对比，无敌兔禁止保存文件，所以我不能衡量RAWs文件（顺便说一下，CS3无法打开无敌兔的RAWs文件），这些只是&评估&。

和尼康的D3以及D700相比，也许噪点更多一点，但是我看不出有巨大的差距；要记住我没有可能进行肩并肩的对比并且由于不允许保留样片文件，因此我无法评估RAW的效果（并且CS3无法打开无敌兔的RAW格式），这些仅仅是&估计&而已。

The main contents are as follows:Firstly, starting with the general situation of soil erosion and the harms caused by it, the causes leading to the local soil erosion problem are analyzed comprehensively in the paper. And connecting with the measures taking place, sticking points towards the career of soil and water conservation are expatiated upon.Secondly, Back-Propagation Neural Network, One of Artificial Neural Network is used to set up a modal about the connection of the soil erosion modulus and seven factors impacts on it, such as, rainfall, rainfall largest intensity in 30 minutes, runoff coefficient, vegetation cover percent, rate of granule, rate of physical viscidity-clay, the rate of organic matter. Through the comparison with linear regression model, the second regression model, the Chinese Soil Loss Equation, it illustrated that BP Neural Network modal is more accurate than the other three modals in forecasting the mount of soil erosion, and the BP Neural Network will have some applicability in forecasting in soil erosion.
