Using biological reactor, without any extra nutriments, white rot fungus was directly absorbed and fixed up on the surface of cinder which was used as the carrier of sorption. Compressed air was sent into biological reactor by one coniform room which located at the bottom of the reactor. Deinking effluent was continuously transferred from one quadrate reserving pool to the reactor by a small pump.

In this thesis, two methods, called stepwise threshold segmentation and contour map threshold segmentation, are proposed.

本文提出了循环递增阈值分割法和等高地图分割法这两种图象分割算法，较好地实现了激光扫描共焦显微生物医学图象的目标分割。

The heuristic method emploies a genetic algorithm in reducing the redundant attributes of all attributes. Besides taking fitness function as its heuristic function for its selection operation, the genetic algorithm uses the attribute\'s information entropy to construct the heuristic function for its mutate operation, and in this way it markedly elevate the convergence speed of attribute reduction.

启发式方法采用遗传算法进行属性约简，除了存在于选择操作的适应度启发函数外，还在变异操作中以信息熵为基础构造了启发函数；穷举方法基于循环队列自底向上约简，通过剪枝有效地提高了属性约简集的穷举速度。

The result of the ecology survey shows that the water circulation between the algae pond and the culture pond can control the content of chlorophyll a and increase the dissolved oxygen in the culture pond. The growth rate of Corbicula fluminea cultured in the water saving system is faster than that cultured in the common system.

结果显示节水养蚬池，利用施肥产生藻水的肥水池配合养蚬的养殖池的部分水体循环交换，确实可以显著地达到控制水中叶绿素a含量与适当透明度、并有增加水中溶氧及促进池蚬的成长效果，若管理良好时并有促进水质特别是营养盐的净化作用。

The preventive measures for the harmful defects of alkali metals are as follows: 1, reducing the alkali metals content in the raw materials; 2, increasing the MgO content of the sinter , decreasing the basicity of slag , decreasing the Si content of the pig iron, increasing relative slag volume; 3 , introducing prereduced ore pellets or partly reducted sinter; 4increasing the ability of coke resisting alkali metals; 5, using refractories that have the ability of resisting corrasion of alkali metals; 6 , cleaning the blast furnace periodically. The above recommendations are necessary for decreasing the circulation and accumulation of alkali metals effectively in blast furnace, reducing the harmful influence of alkali metals on blast furnace, increasing the smelting intensity, decreasing the coke rate, improving the gas permeability.

基于碱金属对高炉冶炼的上述危害，本文结合湘钢高炉的实际生产情况，通过理论分析、计算以及其他钢厂防治碱害的经验，提出防治高炉碱害的措施：1、减少入炉原、燃料的碱金属含量；2、提高烧结矿中的MgO含量、降低炉渣碱度、降低生铁含硅量、适当增加渣量；3、采用预还原的金属化球团或部分还原的烧结矿；4、提高焦炭的抗碱能力；5采用抗碱侵蚀的耐火材料；6、周期性性洗炉，以有效地减少碱金属在高炉内的循环富集，降低碱金属对高炉的危害，提高高炉的冶炼强度，降低焦比，改善高炉透气性。

According to the present situations of protected area in China and referring to the definition and category abroad, we suggested the forest natural protected area mainly include three types as follow: Nature Reserves (NR; types of forest eco-system), Forest Parks and Public Welfare Tree Farm. Researches of evaluation on ecotourism resources of forest natural protected area focused on two aspects basically: to appraise and account the ecotourism resources monetarily from the standpoint of pure economics; to assess the exploitability of ecotourism resources based on the theories of conservation biology and ecology, in which finding the reasonable equilibrating point between protection and: utilization was emphasized. On the studies of development pattern of forest ecotourism resources, it is necessary to deal with the relationship between protection and exploitation correctively, namely to put the protection as the first consideration and balance the "Tree r.1ajor Benefits" so that prompting the virtuous circle afforest ecotourism.

根据我国自然保护地的实际情况，参考国外自然保护地的定义与分类方式，可认为我国的森林自然保护地主要应主要包括森林生态系统类型自然保护区、森林公园及公益林场三种类型；森林自然保护地的生态旅游资源评价研究主要集中在两方面：一是单纯地从经济学角度对旅游资源游憩价值进行货币化评价与核算，二是从保护生物学和生态学角度对资源的可开发性进行评价，其侧重在于找到保护与开发的的科学平衡点；在森林自然保护地旅游资源的开发模式研究上，必须正确处理开发与保护的关系，把保护放在第一位，坚持"三大效益"兼顾的原则，才能实现森林生态旅游资源开发与保护的良性循环。
