Moreover,thc rationality about calculating tolerance unit by using the grometrical average is discusscd in comparison with relative reeor by using the midline value which is in a basis diameter step.

本文给出了几何平均值与算术平均值最大相对误差关系的证明，并通过对尺寸分段内按中线值的相对误差的比较，进一步论述了按几何平均值计算公差单位的合理性。

Should this experience prove false and Israel actually repent, forgiveness and national life would be by no means hopeless; and therefore utterances like v. 4 and 14, however inconspicuous they may be in comparison with the denunciatory passages, are by no means to be overlooked, and certainly not to be held as spurious.

应这方面的经验证明，虚假和以色列，其实悔改，宽恕和国家生活会，绝非无望；因此，话语像五，四和第14条，但不显眼，他们可能会在比较与denunciatory通道，是决不被忽视，当然也不是将要举行的作为杂散。

By use of the method of integral equation, the second kind Fredholm's integral equation was deduced to solve the interaction factors of pile-pile, pile-soil and soil-soil. Using the principle of superposition, the piled raft foundation was calculated. The validity of the proposed method was verified through comparison with solutions obtained using other methods by existing theories of elasticity.

采用积分方程法推导出求解桩－桩、桩－土和土－土间相互作用系数所需要的第二类Fredholm积分方程，利用叠加原理对桩筏基础进行计算分析，通过与常规弹性理论方法计算结果的比较验证了本文方法的正确性。

In addition, the test results of frictional pressure drop in smooth tube with water and kerosene are compared with the calculated results with homogeneous model and Friedel formula respectively. By comparison, more suitable calculation formula are recommended for smooth tube.

此外分别研究了两种工质在光管中的两相摩擦阻力特性，将实验结果分别同以均相模型和Friedel经验公式的计算值进行了比较，推荐了适合于光管中摩擦阻力计算的经验公式。

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.

本文以霍山县作为皖西大别山区的典型区域，主要研究了以下内容：(1)从介绍霍山县土壤侵蚀状况以及所造成的危害入手，全面分析了导致当地土壤侵蚀发生的原因，并结合当地采取的水土保持相关措施，阐述了当地水土保持工作的症结所在；(2)结合上土市水土保持试验站多年实测资料和2005年实验资料，应用BP神经网络理论，建立了次降雨土壤侵蚀量与次降雨量、最大30min雨强、径流系数、植被覆盖度等因子之间关系的模型，并通过BP神经网络的预测模型与一次回归模型、二次回归模型、CSLE模型之间的对比分析，说明了建立的BP神经网络模型在土壤侵蚀预测可以取得较回归模型和CSLE模型更高的精度，也说明了BP神经网络理论在土壤侵蚀预报中具有一定的适用性。
