查询词典 efficiency

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.

The energy exchange analysis indicates that gliding energy efficiency is dependant on the lift drag ratio of the wings and gliding angle of the hull. Through the calculation in this thesis, it can be concluded that enhancing the lift drag ratio can largely improve the energy efficiency when the gliding angle is in the range of 10to 40 degree, and when lift drag ratio is fixed, there exists a special gliding angle for the maximum of the efficiency, which provide theoretical basis for the design of operating parameters.

通过能量转换分析，得出滑翔机航行效率由机翼升阻比和机身航行角决定，航行角在10~40度范围内，增大机翼升阻比可显著提高航行效率；并由计算得出，在升阻比一定的情况下，总存在一个使滑翔机航行效率达到最大的航行角度，为样机工作参数设计提供了理论依据。

As shown in the experimental results: as the conductor of petroleum biological degradation, the quantity of microorganism is the important factor of petroleum degradation efficiency, the huge natural capacity of microorganism in soil is its foundation of bioremediation; petroleum density in certain scope do not affect for the degradation efficiency of petroleum, and in the density of 5%, its initial degradation efficiency is higher, however after training 40 days, this kind of advantage change weak gradually, the reason may be the petroleum of high density probably having certain poison role for microorganism; the best ecological condition of petroleum contaminated soil bioremediation is that nutrition material C: N = 60, electron receives body HiOi joining quantity amount to 12 mg/g, water content is 50%, surface activator is anion surface activator of 12 Wan base benzene sulphur sour sodium; the relation of primary and secondary of factor is water content, surface activator, nutrition material and electron receiver.

试验研究结果表明：作为石油生物降解的执行者，微生物的数量是影响石油降解效率的重要因素，土壤中微生物的巨大的自然容量是其生物修复的基础；石油浓度在一定范围内对石油的降解效率并没有影响，并且在5％浓度时，其起始降解效率较高，但是到了培养40天以后，这种优势渐渐变弱，可能还是高浓度的石油对微生物有一定的毒害作用；石油污染土壤生物修复的最佳生态条件为：营养物质C：N为60，电子受体H_2O_2的累计加入量为12mg/g，含水量为50％，表面活性剂为阴离子表面活性剂十二烷基苯磺酸钠；因素的主次关系为：含水量、表面活性剂、营养物质和电子受体。

It is found that the damage of the lines is mainly aroused by heat effect and electric force generated by impulse current circuit, and the effect is different between different current value and different lines.

Because of the low efficiency of economy collectivization, collective property rights can"t last for a long time and central government has to communicate with community and peasants. Rural community collective property rights become subjective through balancing benefits by formal or informal trading. With the changes of political and economical environment, the contradiction of rural community property rights between fair and efficiency become more and more serious. Collective lands and collective enterprises advance to privatization gradually. There are two kinds of country collective property rights in the history of its evolution, one offer community common good and the other satisfy peasants" private demand. The collective property rights institution improvement brings efficiency because it privatizes the latter. Because of the limit of industrialization and civilization, land is still the last social welfare of peasants, so rural community must attain the collective property rights to control the pressure of population. Also community has to get money from collective economy.

本文分析的思路是；由于制度变迁的&路径依赖&，农村社区之间的利益分配边界在解放以后得以保持并在集体化过程中得到加强，为社区获得排他性集体产权奠定了基础；由于国家对农村经济的集体化效率极低而不可能长期维持，国家不得不与社区和农民对话，通过正式或非正式的交易平衡多方利益，社区集体产权获得实质性内容；随着政治、经济等环境的不断变化，社区集体产权公平与效率之间的矛盾同益明显，集体土地和集体企业逐渐朝私有化的方向发展；从农村社区集体产权制度变迁的历史来看，集体产权实际上包含两种形式：提供社区公共物品和满足社区农民个人需求，每一次集体产权的制度创新，都是使后者&私有化&而提高了集体经济的效率；但是，受我国工业化和城市化进程缓慢的制约，土地依然是农民最后的生存保障，农村社区必须保持对土地的集体产权以调节人口变化对土地的压力，社区组织行使职能也必须有一定的集体经济提供资金支持。

Because the higher education is a kind Quasi- public product provided with both commonality and exclusion. With regard to equality and efficiency of the higher education, we cannot simply judge by "efficiency first, equity second"or"equity first, efficiency second".

由于高等教育是一种既具有公共性又有排他性的准公共产品，对于高等教育的公平与效率问题，不能简单地以&效率优先，兼顾公平&或者&公平优先，兼顾效率&论处，我国现实存在的高等教育公平与效率问题有力地说明了对此应该视具体情况而定。
