用生态经济沟的经验建设生态经济岗

本文总结了太行山区过去几十年林业生产的教训,把近几年的“生态经济沟”经验,应用到太行山南部低海拔岗坡地形区的开发治理中,提出了建设“生态经济岗”的设想及盘龙岗试点的规划方案。     

乌鳢生长发育的生态因子及其流行病的防治

对非生物生态因子———水、光照、温度、溶氧、降水等和生物生态因子———食物、流行病和群体密度等对乌鳢生长发育的影响及流行病的防治进行了综述。     

二阶拟线性椭圓型Euler方程组解的Pohozaev型恒等式及其应用

本文对于二阶椭圆型Euler方程组 -∑D_αF_(q_α~i)(x,u,Du)+F_(ui)(x,u,Du)=0得到了一些积分恒等式,利用这些恒等式证明了某些方程组非平凡解的不存在性。     

“两田制”与农业双层经营

虽然双层经营体制已经得到确立,但至今其经营客体或对象在实践中仍然是不清楚的,而且就统分结合两方面来看,统的职能也严重不足,致使家庭经营的弊端依然存在,双层经营的功能难以充分发挥.为此.笔者提出,“两田制”是完善双层经营体制的有效形式。它有利于实现农业的适度规模经营,可大幅度地提高农业劳动生产率和农产品商品率,还形成了农村劳动力合理流动的机制,有利于农村经济的全面发展和农业机械化的推广。所以,笔者主张,“两田制”应谈有计划地加以推广.     

Experiment Research on Leachate Treatment of Sanitary Landfill for Municipal Solid Waste

It is difficult to treat landfill leachate in China.Traditional biologic method and physical method always have high expenses,or cann''t reach the discharge standards.The authors use a new biologic method to treat landfill leachate,which is the Wood_microbial System from Japan.The system to be digested by 3 aeration tanks and 1 reaction tank.The comparison combine processed wool_dust broken pieces with the certain grain degree size were throw in the tanks.Dirty and organic matter are in the digest tanks through the aeration reaction and aneration reaction repeatedly.In this experiment the speed of wastewater discharge and oxygen supply has been changed, and the change of biologic system and the effect of pollutant are removed. The optimal treatment condition can be found.The experiment shows that the system has a good result,special for nitrogenous.The BOD is average to do away with the rate to amount to 90%,almost reach the second class or third class for leachate standard.But BOD loading should be not beyond 4 kg/(m 3.d),othrwise,the system will not operate in normally.

互联网环境下的暖通CAD组件模块的开发方法研究

针对单机环境下暖通CAD软件重复开发量大、开发周期长等现状，提出了基于互联网环境的三层体系结构及其开发的通用环境，即整个暖通CAD系统被分为不同逻辑块，开发和管理的工作向服务器方转移，从而使分布处理数据成为可能，基于组件的软件开发是互联网环境中应用软件的主要开发方式，以构架为组装蓝图，以可重用组件为组装预制块，支持组装式软件重用，从而克服人力和物力的浪费，进而为了重用暖通CAD已开发出的功能模块，给出组件逆向工程的开发方法、组装流程和组件管理过程。
