效率

In addition, volumetric efficiency and the in-cylinder pressure behavior during the intake and compression stroke were obtained and compared with the experimental data.

在容积效率、进气与压缩两冲程之缸内压力方面，其数值模拟值与实验值两者间所显示之差异在5%以内；此外，对三组最大进气阀升程之模拟，其所得之容积效率值在趋势上系属合理。

It is could be concluded that the larger pump impeller diameter may obviously increase the efficiency of both conduit and pump system; increasing pump diameter and decreasing its rotational speed is consistent with reducing nD value.It is suitable to pump system with low head to choose lower nD value, so as a hydraulic model of axial flow pump with the better hydraulic characteristics could be obtained.

结果表明：选取较大的水泵叶轮直径将显著提高流道效率和泵装置效率；&增径降速&与降低nD值是一致的；在泵装置扬程较低的情况下，选取较小的nD值便于选用到水力性能较好的轴流泵水力模型。

Using the models developed by Basu,Jones and Richardson,the paper analyzes the cross-section data,the differential data and pool data.

通过应用Basu模型、Jones模型、Richardson模型的截面、差分和混合数据分析，发现内部控制评价报告的披露与审核对会计信息稳健性、可操控应计利润和资源配置效率的促进作用不显著，自我评价报告的自愿性披露与审核没有显著地提高内部控制的效率。

The existing stone cutting tool, the tool bit is constituted by the sole grade's grinding material, when cutting the rough stone, the cutting speed is quick, the cutting efficiency is high, but the cutting surface fluctuates in a big way, becomes rough, after the cutting, grind and polishing take long time to do, if use the fine grinding compound, the cutting face is smooth, but the cutting speed is slow, the cutting efficiency is low, therefore the existing stone material cutting tool cannot have the high efficiency to cut the stone which have the smooth cutting surface, in view of this, how to keep the high working efficiency and get smooth cutting surface?

现有石材切具刀头由单一粒级的磨料构成，使用粗料时，切割速度快，切割效率高，但切割面起伏大，变得粗糙，切割后研磨抛光耗费时间长，使用细磨料，切割面较平整，但切割速度慢，切割效率低，因此现有石材切具不能高效率地切割出平整的石材，针对这一现状，如何既能高效率切割，又能使切割面保持平整呢？

It includes the dead-weight of social welfare created by monopolistic pricing, X-inefficiency caused by monopoly, resource loss created thanks to consumers choosing substitute products and efficiency loss caused by the rent-seeking of monopoly.

垄断的社会成本主要包括垄断定价造成的社会福利净损失、垄断导致的X-非效率、消费者选择替代产品所造成的资源损耗以及垄断寻租活动造成的效率损失等。

So in this paper we discuss the content of version management from data storage, and put forward two models of difference storage. Constructing storage threshold unites difference storage and full storage in order to balance space efficiency and time efficiency. It not only improves the answer time of version access but also reduces storage space.

因此本文从数据存储的角度讨论了版本管理的内容，提出两种差值存储模型，构造了版本存储阈值来将差值存储与完整存储相结合，从而有效地在空间效率和时间效率上进行平衡，不仅提高了版本存取的响应时间又减少存储空间。

The generation of blue light through direct frequency doubling of 860nm has been achieved in our two typical samples. Sample A and sample B have the number of domain laminas of 460 and 290 respectively, and the SHG efficiency are 4.2% and 3.5% in the two samples.

通过在不同的晶体偏角下进行基波波长扫描的倍频效率的测量，给出光学超晶格样品的&允许偏角&，超过这个角度，非线性倍频转换效率急剧下降。

However, it is explicit that this system is idle at daytime or with insolation. This structure of the proposed illuminating system has not been optimally used. For increasing energy conversion efficiency, many topologies have been proposed and implemented. An alternative to solve this structure is the use of direct-connected of power supplies.

然而，此种电路架构系统往往在白天或日照强度大时闲置运作，降低整体系统效率，此传统架构并非最理想的照明系统，因此为了提升转换效率，很多论文也纷纷提出新的系统架构并实际运用。

Compared with the control, 10–50 mg/L ALA had no significant effect on the leaf water use efficiency at flowering and milky stage, while increased the leaf water use efficiency significantly at dough stage.

在开花期和乳熟期，10～50 mg/L ALA处理的叶片水分利用效率与对照没有显著性差异，但在腊熟期，叶片水分利用效率较对照有显著性提高。

The saving-water effect of Radish and Cabbage under PFM and appropriate irrigation,and the drought-resisting of radish seedling which seed was soaked by CaCl_2 were systematicly reseached by field observation and the experiment in door.The main results were summaried as follows:The soil temperature of 0~20cm cultivated layer was increased 3-4.5℃ in early growth period was only 1℃ in late growth period by PFM;there was more water saved up to 20.84mm in 0~60cm soil layer by PFM than no PFM in the early growth period of Radish;the yield and water use efficiency of Radish in L4 were exceeded respectively 10.1% and 21.9% of that contrast, the yield and water use efficiency of Cabbage in G4 were exceeded respectively 8.7% and 26.58% of that contrast, under PFM and appropriate irrigation.

主要研究结果如下：地膜覆盖在植株生长前期耕作层平均可增温3～4.5℃，在生长后期增温幅度减小，仅有1℃左右；地膜覆盖在植株生长前期可有效的保持土壤水分，在萝卜生长前期，使0～60cm土层内多储水20.84mm；在覆膜不灌水充分利用自然降雨的条件下生产萝卜，可比裸地正常灌水萝卜增产10.1%，水分利用效率提高21.9%；覆膜只浇一水生产甘蓝，可比裸地正常灌水生产甘蓝增产8.7%，水分利用效率提高26.58%。

But we don't care about Battlegrounds.

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
