There were a great deal of kinds of the grass with high quality and quantity fed to fish To determine the best symbiosis ecosystem of fish and grass on a closed system circulated yearly, several cold and warm grass was selected to analyse the adaptability and nutrition absorbed. It indicted that Lolium multiform Lam. and lemarthria compressa were the best option due to high adaptability of wetness, high coarse protein, fat and fibre and so on in the leaf, high biomass, high bio-filtration effect of N and P, adaption to the low or high temperature, resist to the plant diseases and insect pests, and the food of fish whose forage was grass.

鱼用优质高产牧草的种类繁多，为确定最佳的鱼草共生周年循环系统，本文选择几种冷季牧草和暖季牧草进行生长适应性与营养吸收研究，分析表明，多花黑麦草和扁穗牛鞭草是最佳的冷季牧草和暖季牧草，它们耐水性强，叶片中所含的粗蛋白、粗脂肪、粗纤维等化学成分高，植株的生物量也高，生物过滤养殖废水中的氮和磷效果好，而且可以适应外界环境的低温或高温，抵抗病虫侵害，同时为草食性鱼类喜欢食用。

Emerging economies are being hit hard by weakening exports and the collapse of private capital flows. The G20 summiteers cannot prevent this, but they can stave off a slump with zealous and co-ordinated action to prop up domestic demand and provide resources to cash-strapped emerging economies.

由于出口的减少，私人资本循环系统的崩溃，新兴经济体受到严重的打击。G20峰会不能阻止这一切的发生，但是它能够用积极的，协调的措施来抵御经济衰退--扩大内需，帮助缺乏现金的新兴经济体。

First, developments related to modeling of components of the Ground Source Heat Pump system are presented-vertical ground loop heat exchanger, water source heat pump, standing column well, and several types of supplemental heat rejecters used in hybrid GSHP systems.

首先给出了地源热泵系统各部件建模方面的进展，包括竖直埋管地热换热器、单井循环系统以及在地源热泵混合系统中采用的几种辅助散热装置。

On the basis of analyzing the thermodynamic properties and cycle performance of pure refrigerants, the paper optimizes their concentration while screening NARMs used in wide variable-temperature heat source. The practical applications of NARMs, such as R22/R123, R123/R125 etc., are studied in geothermal heat pump, seawater heat pump, air dehumidification system and dual-evaporator domestic refrigerator. The results show that the NARMs can match the limitation of a pinch point at the air-side exit of heat exchanger, reduce the unreasonable heat transfer temperature difference, and improve the COP of system. The above conclusion is proved by measuring the cycle performance of R12, MP39 and R11/R22 in a two-evaporator experimental system.

其次，本文在工质热物性和变工况循环性能分析基础上，筛选和优化了适应外部大变温热源约束条件的非共沸混合工质及其浓度配比；讨论了相变温差较大的非共沸混合工质（如R22/R123、R123/R125等）在地热源供热热泵、海水源供热热泵、双门冰箱和热泵空气除湿的应用，计算分析表明制冷与热泵系统采用相变温差较大的非共沸混合工质有利于弱化传热过程的&窄点&的约束，减小传热过程中的不合理温差，提高系统COP值；通过建立双蒸发温度循环系统试验装置，对R12、R22/R11和R22/R152a/R124循环性能进行实验研究，结果与理论分析一致。
