In allusion to the actual status of city Service pipe network management,the thesis presents the collectivity project that to establish the city service pipe Network geography information manage system,based on the research and analyse of the lack which exist in the course of running water pipe network and the difficult problem which need to be solved. The computer internet applications is developed and empoldered.

Two kinds of representative CC-Repowering (feed water heating repowering,full firing repowering) were analyzed and compared in this paper. Aremarkable phenomenon was observed: Efficiency monotonouslychanges with work-ratio in FF-Repowering system; but in FWH-Repoweringsystem, there exists an optimal ratio at which point the efficiency isthe highest. Another phenomenon to be paid attention is that under somework-ratio, the efficiency of FWH-Repowering is higher than that ofFF-Repowering, giving rise to correcting the conventional concept.

本文对两种典型的联合循环系统(排气助燃型FF-Repowering和给水加热型FWH- Repowering)进行了热力学系统模拟研究，得到了随燃机汽机功比变化排气助燃型系统效率单调变化以及给水加热型系统效率存在极值点的现象，并发现了一定燃机汽机功比下给水加热型效率大于排气助燃型的特殊规律。

High pressure supply water heater uses discharge steam from steam turbine to heat supply water of boiler, and makes supply water to reach required temperature so as to improve thermal efficiency of power plant and to ensure output of the unit.

高压给水加热器是利用来自汽轮机的抽汽，来加热锅炉给水，使给水达到所要求的温度，从而提高电厂的热效率和保证机组的出力。

The design mainly contains living water supply、fire water supply and sprinkler systems water supply.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
