GEHP has much predominance that the traditional EHP hasn't: Firstly, gas is a clean resource and GEHP has much superiority in environmental protection ; Secondly, avoiding the process of the electrical generation in power plant and its transmission to the end, GEHP has higher PER than EHP; Thirdly, GEHP system avoids the "cold blow" associated with EHP by recovering and using waste heat from engine jacket coolant and exhaust; Finally, the engine speed can be easily adjusted to match varying heating and cooling loads and get higher IPLV A GEHP system is designed in this paper, on the basis of which an experiment table has been built to test the system performance.

本文对系统流程进行了设计，对装置各个部件进行了选型和计算，对使用燃气作为空调能源的可行性进行了评价，并且在此基础上搭建了一个用于实验分析的试验装置，对系统性能参数、变转速部分负荷特性、发动机余热回收性能进行了理论分析和实验研究。

In addition, based on the fact that phosphorus is usually the limiting nutrient for nitrogen fixers, a novel method named "nitrogen fixing bacterial growth potential" test, for evaluating limiting nutrients, was developed.

Each two kinds of method to calculate slenderness ratio, flange and steel stress of the tension area were listed, the results were compared to the test,and the conclusion was draw.

分别列举了包括规程法在内的长细比、受拉翼缘、纵筋应力两种计算方法并与试验结果进行了对比，对不同计算方法进行了评价。

Then,based on the"U"distribution of the flashover voltage values of composite insulators with the increase of the temperature cycle in the cold fog,the flashover performance evaluation method is brought forwa.

最后，分别利用该冷雾试验方法和传统蒸汽雾法评价了一种复合绝缘子短串试样的污秽闪络特性。

Based on the crossing data among these flatfishes, the relationship between pairwise genetic distance and hybrid fitness was evaluated. The findings indicated that positive relationship might exist between genetic distance and hybrid fitness. The pairwise genetic divergence between species decreased as the interspecific hybrid fitness largened. These results implied that speciation clock might exsit in Pleuronectiformes.

根据这几种鲆鲽鱼的杂交是否可行的试验结果，评价种间遗传距离与杂交可适度的关系，结果表明，这8种鲆鲽鱼类的种间遗传距离与杂交可适度呈显著的负相关(r2 = 0.805，P 0.01)，即种间遗传分化越大，杂交成功的可能性越小，这表明鲆鲽鱼类中可能存在物种进化的不亲和钟。

Base on mensurating and analysis about grass growth speed、variance of the green parts、PH data of soil and fertilizer、each tantalum and nutriment in experiment, there is summarization and evaluation for each important gene of impacting Green grass character and making suggestions for Green maintain work in future.

试验期间通过对草坪生长速度、绿叶率变化、土壤和水源的pH值、主要金属元素和营养元素含量、果岭球速等指标的测定和比较，总结评价了影响果岭坪用价值的各个重要因素，并在此基础上对该球场今后果岭养护工作中的重点和方向提出了建议。

In different degree of saline and alkali conditions controlled in lab or under field, contents as followed were determined: the absorption, transportation and distribution of major cations Na~+, K~+, Ca~(2+and Mg~(2+) in indicator plant; organic solute, and antioxidase activities, including superoxide dismutase, catalase and peroxidase POD characteristics of individual, population and community of the plant. Responses of the indicator plant to environment from physiological to community aspects were systemically discussed in this document.(1 Vegetional characteristics and edaphic indicators including bare patch index, dry biomass, percent cover by perennial plants, growth indicators of Leymus chinensis, soil organic matter and pH were sensitive to saline-alkali grassland degeneration.

运用室内控制和野外试验相结合的方法，调查和测定在不同土壤盐碱条件、不同季节里，主要元素Na~+、K~+、Ca~(2+)、Mg~(2+)在植物体内吸收、运输和分布的变化状况；研究不同土壤离子浓度下，指示植物体内渗透调节物质——脯氨酸和糖类、超氧化物歧化酶、过氧化物酶和过氧化氢酶活性等指标的变化响应情况；研究不同盐碱梯度下，植物个体、种群、群落的特征；系统的从生理生态角度探讨指示植物对盐碱环境的响应：(1)植被特征指标：裸地指数、生物量、多年生植物覆盖率；羊草生长状况指标：土壤有机质含量、pH可作为松嫩平原退化评价的指标。

Nineteen quality parameters of 67 wheat landraces in Sichuan province were investigated and analyzed.

以67份四川省的小麦地方品种为试验材料，测定其19个品质指标并进行品质评价，旨在为小麦品质改良提供信息。

The outputs of ZELIG model was used to 1evaluate the environmentalfactors which influence the growth of tree species of broad leaf korean pine forestin Changbai mountain;2simulate the dynamics of main types of forest in broad leafkorean pine forest zone and 3simulate the effect of selective cutting experiment onbroad leaf korean pine forest.

本文以森林Gap模型的理论为基础，通过大量的外业调查，建立了长白山阔叶红松林的ZELIG模型，并根据ZELIG模型的模拟结果对长白山阔叶红松林带的树木生长的环境因子进行了评价，同时对阔叶红松林带内的几种主要的森林类型进行了动态模拟，最后运用ZELIG模拟了阔叶红松林的择伐试验。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
