This paper introduces the development process of wastewater disposal,it's auto control system,the level of nowadays and several new techniques of China and foreign countries. The immanent structure,control rules,main features and design methods of auto control systems in wastewater disposal process are studied in this paper. Aiming at four typical parameters,such as temperature,dissolved oxygen,PH and the planes of water,the Distributed Control System is designed,composed by PC called epigyny computer and SCM 8098 called hypogyny computer,and some sensors,shift deliver utensils and related meet orifices of parameters gathering and figures communication. The idea and work processes of some program modules are also introduced here. The programs in epigyny computer include the program of mutual interface between operator and computer,figure disposal program and chart output program,which are exploited with Visual Basic 6.0. And the programs in hypogyny computer are composed by figure gathering program,the progr am of supervision and control of system,communication program and meet orifice program between assemble language and VB,which are designed with assemble language.

In order to find out completely the soil-wheat contaiminated by heavy metals in Tianjin sewage farm, we collect samples on the dry land and examinate contents of heavy metals in soil-wheat system. Firstly, the anthor evaluates that soil irrigated by sewage that has been contaminated slightly, the main polluting factors are Cd and Zn, and then the anthor evaluates soil according to different regions, soil types and irrigating water. Secondly, the anthor analyzes content and enrichment ability of heavy metals in different part of wheat, evaluates wheat is contaiminated by Cd widespreadly, only few samples polluted by Zn.Finally the anthor put up correlative analysis about heavy metal contents in the soil-wheat system, as well as plant enrichment coefficient and some physico-chemical properties of soil, and establishes a prognostic model about heavy metal content among wheat spike, soil, soil types, PH, organic matter and salinity with the quantifying theory.The prognostic accuracy of primarily contaminative factors is the best with compound correlative coefficient examining, the model can be founded.With improvement of living level, people need cleaner food.
为全面了解天津市污灌区农产品生产地土壤和旱地作物小麦的重金属污染状况,我们于2004~2005年对全市污灌区的土壤和小麦进行了采样,在对该区土壤—小麦系统中六种重金属元素(Cd、Cu、Pb、Zn、Cr和Ni)的含量进行检测的基础上,本文首先分析评价了污灌区农田土壤的环境质量总体已达到了轻度污染水平,主要的污染因子是Cd和Zn,同时对污灌区农田土壤分区县、土壤类型和不同灌水类型进行了评价;然后分析了重金属在小麦不同部位的含量与富集能力,评价了污灌区旱地作物小麦普遍遭受了Cd的污染,只有个别样点遭受了Zn的污染;最后对土壤—小麦系统重金属含量间以及植物富集系数与土壤部分理化性质间进行了相关分析,由于土壤类型是定性变量,本论文以数量化理论建立了小麦穗实中重金属含量与土壤中重金属全量、土壤类型、PH值、有机质和全盐量间的预测模型,经复相关系数检验,污灌区主要的污染因子Cd和Zn的预测精度最高,模型可以成立。

The study was supported by National Nature Science Foundation of China of ""Biological foundation study of electrical indexes assessing tree vigor"". The mechanism of tree's leaf and stem capacitance and the application of electrical indexes under environmental stresses were studied. The main conclusions are summarized as following:(1) The leaf capacitance had significant positive correlations with leaf exosmosis electro conductivity, exosmosis percentage and leaf absolute moisture content, had significant negative correlations with leaf electrolyte electro conductivity and had no correlations with leaf relative water content.

At the confluence zone, due to the jacking of current from main stream and tributary stream, the mixing and turbulence of current is so strong and the loss of energy is so large that the balance of water and sediment is broken which could causes sediment particle and coarse grain to deposit and forms shallow shoal at river mouth or eyot.
天然河流中存在着大量的干、支流交汇的河段,在干支流相汇处,由于干、支流两股水流相互顶托,交汇区内水流紊动掺混作用强烈,能量损失很大,干、支河流原有的水沙平衡状态被打破,可能导致泥沙颗粒、尤其是粗颗粒卵石在汇合口处大量淤积,形成河口浅滩或江心滩。
