The contents of the thesis are related to water source heat pump unit and ground heat exchanger.

近年来地源热泵系统的在我国得到越来越多的重视。

Supported by the National Natural Science Foundation of China(Study on Heat Transfer Characteristics of Downhole Coaxial Heat Exchanger in Convection Geothermal Reservoir )and Tianjin Development and Plan Program of Science and technology(Study of Ecologic Architectural Energy System), the thermal performance exploiting earth energy for heating and cooling is studied in this paper,and its main purpose is to offer reference for increasing the percent of renewable energy in Ecologic Architectural Energy.

本文在国家自然科学基金（井下换热器周围对流型地温地层内的传热特征研究）和天津市科技发展计划项目的资助下，重点研究了地表热能高效利用中的传热与热力性能问题，为可再生能源在生态能源建筑中发挥更大的作用提供依据。

The heat exchanger has reduced volume, and is hermetical, low in cost and high in heat exchange efficiency.

这样减小了整个热交换器的体积，同时保证热交换器的密闭性，造价低，交换率高。

Although there are many kinds of water heater including solar water heater, electric water heater and gas water heater. The gas water heater is the first choice in our country. It burns the NG or LPG to absorb the heat to supply hot water for bath by heat exchanger. It takes also 156 kiloliter oil a year in Taiwan.

虽然热水器有很多种，包括太阳能热水器、电热水器、燃气热水器等；但因燃气热水器为国人目前使用最多的一种热水器，其使用天燃气或液化石油气作为燃料，冷水透过热交换器吸收热量变成热水供洗澡之用，瓦斯年使用量约为156万公秉油当量。

The effect of fluid flow nonuniformity on heat exchanger's efficiency is the most important one among them because it can intensify longitudinal wall heat conduction and the maldistribution of interior temperature.

因为物流分配的不均匀会加剧换热器内部温度场分布不均匀和纵向传热，从而加剧了换热器整体效能的下降，所以物流分配不均匀性对换热器效能的影响在三者中是最主要的。

When joining and welding on steeliness tubeplate and red copper heat exchange tube in the tubular heat exchanger,whether we adopt welding way or not expanding,evermore there are leakages and seepages as some troubles.

在管壳式换热器钢制管板与紫铜换热管连接时，无论采用焊接还是胀接，经常出现的问题是泄漏和渗漏。

Thus, the heat exchanger having a specified heat exchange capacity and firmly supportable on a base can be provided.

因此，可提供具有指定热交换能力和可牢固支撑在底部上的热交换器。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

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。
