结果表明，在前面的推进器发动机实现了液体冷却效率更高的起飞了在前面比运行时的光线的引擎实现最高效率较高；只有当纺纱被聘用。

The spikes per plant of diploid and tetraploidspecies were higher, but the kernels per spike, 1000 kernels weight and grain yield werelower than those of hexaploid and octoploid species. The NYE, NHI and NPE of diploidand tetraploid were lower; NDE was higher than these of Hexaploid. Variation of NPE andNYE was higher than other NUE indexes, which indicated that NPE and NYE could beused as indexes for NUE differences in different wheat related species.

与普通小麦相比，二倍体和四倍体材料单株穗数较多，但穗粒数、千粒重和产量比较低；氮素籽粒生产效率、氮素收获指数和生理效率比较低，具有较高的氮素干物质生产能力；NYE和NPE的变异性较大，可以作为小麦不同近缘种氮素利用效率差异的主要指标。

This paper mainly inquired into the characteristics of the ferment bed pig - raising technique and its applying in realizing the cleaner production of pig farms. ferment bed ; cleaner production ; pig - raising technique ; waste treatment

但由于发酵床技术主要靠微生物降解猪场废物，而目前所使用的菌种分解效率不是很高，使得单位面积饲养的猪数量有限，另外由于猪舍是半开放式的，受外界的环境变化的影响，如何使菌种在不同的气候条件下都能发挥较高的效率也是一个需要解

Results UCMSCs could be effectively infected by adenovirus containing GFP gene in vitro, the transfection efficiency has the dose-effect relationship with multiplicities of infection.

结果 腺病毒介导的GFP基因对于UCMSCs具有较高的转染效率，转染效率与MOI值具有量效关系，当MOI为100倍时，转染效率达95%。

According to correlation analysis of yield and properties, the following traits should be included, higher chlorophyll content and big area of ear leaf at heading period, higher N content of grain, NUE and N harvest index in choosing cultivars at low N, and the big biomass at heading period and maturity should be included at high N.

据性状与产量相关分析表明，低氮条件下应选择抽丝期穗位叶叶绿素含量高、抽丝期穗位叶叶面积大、籽粒氮含量高、氮效率高和氮收获指数高的品种；高氮条件下应选择抽丝期生物量大和成熟期生物量大的品种。

Set beer as an example, the mixing turbidity could be as low as below 0.5EBC. A kind of special filter part- filter candle sticks, which are a certain number of hollow metal sticks with special structure and constant space in between each other, is one of the best filter parts till now for its high efficiency and conveniency of cleaning. It is ideal diatomite filter equipment for its small operation space, high efficiency and low running cost.

经过滤的液体能有效除去液体介质中的颗粒物质、酵母菌和其他微生物，使过滤后的介质清澈，光亮（以啤酒为例，混合浊度可达0.5EBC以下）该机采用结构特殊的过滤元件---过滤烛棒，是若干根结构特殊间隙恒定不变的空心金属棒体，过滤效率高，易清洗，是到目前为止最优秀的过滤元件之一，该机占地面积小，生产效率高，运行费用低，是最理想的硅藻土过滤设备。

Given the same total flow effusion from holes, the results show that the heat shield gets a higher average cooling effectiveness when the opening ratio is 3% compared with 6%; cooling effectiveness is sensitive to the height of ripple board, the heat shield gets the highest cooling effectiveness when the dimensionless height of ripple board is 1% compared with 2% and 3.33%; but there is a little influence on the cooling effectiveness of the liner with the change of the diameter of holes and the height of cooling passage.

研究表明：在气膜孔出流总量相同的情况下，3%开孔率比6%开孔率的隔热屏平均冷却效率较高；波纹板高度对隔热屏冷却效果影响较大，波纹板无量纲高度为1%比波纹板无量纲高度为2%和3.33%的隔热屏平均冷却效率高；孔径和冷却通道高度的改变对隔热屏冷却效果几乎没有影响。

The USM is a kind of new electrical motor which develops in recent 20 years, it broke through the traditional concept of electrical motor. It didn"t have the electromagnetism winding and the magnetic circuit, and it didn"t uses the mutually electromagnetism to transform the energy, moreover, the volume of electrical motor is small, the weight is light, the transfer efficiency is high. For it was so small, so light, and so thin, it have begun to use on automobile. But the usage of superconductivity electrical motor is still in the experimental stage at present. The main reason is that the super conductivity material has not realized the high temperature, but with the development of technical, the possibly uses of superconductivity electrical motor in the big horsepower like automobile generator and on actuation electrical motor causes the electrical machinery to be smaller in volume, lighter in weight, and higher in efficiency.

超声波电机是近二十年来发展起来的一种新型电机，它突破了传统电机的概念，没有电磁绕组和磁路，不用电磁相互作用来转换能量，体积小、重量轻、转换效率高，很小、很轻、很薄，在汽车上已经开始使用；超导电机的使用目前还处在实验阶段，这主要的原因是超导材料还没有实现高温化，但是，随着技术的发展，超导电机可能使用在汽车的起动机和驱动电机这些大马力上，使原有的电机体积更小，重量更轻，效率更高。

We study technical spillovers of foreign direct investment in China in this paper based on provinces panel data.

利用中国29个省区1994－2003年面板数据，本文研究了外商直接投资对中国省区经济增长效率的影响，结果显示，相对于国内企业，外资企业具有相对较高的技术效率，外商直接投资对中国省区技术效率的提高有显著的溢出效应，外商直接投资的技术溢出呈现一种区域的差异性，而对外贸易对中国省区的技术效率并没有产生明显的技术溢出，在分区域研究的时候发现，对外贸易对西部省区技术效率的提高产生了显著的抑止作用。
