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。

Simpson's central air conditioning products conform to American Simpson quality manage and control system, stick to the tenet of energy conservation and environment protection.

According to the running state of the Boiler in Datang Huxian County Second Power Plant, the steam atomizing oil gun was reconstructed to the air atomizing oil gun. The compressed air was used to the atomizing medium of the oil gun that a great quantity of the steam was reduced when the boiler had been no running and steady boiling. Definitely the steam may be supplied by the steam turbine the fourth pulling out section,oil gun's use was not limited by the pressure of the atomizing steam at lower load. It has been realized the energy conservation efficiency function.

大唐户县第二发电厂根据锅炉运行的实际情况，通过将蒸汽雾化大油枪改造为空气雾化油枪，采用压缩空气作为油枪雾化的介质，大大降低燃煤锅炉起停及稳燃时蒸汽耗量，辅汽联箱不需要冷段再热部分供汽，完全可以由汽轮机四段抽汽供汽，油枪的使用不受低负荷时雾化汽源压力低的限制，达到了节能增效的作用。
