Then the overall performance of the cycle with different organic working fluids was analyzed individually. Compared with the conventional cycle configuration used for only recovering the exhaust heat, the present cycle has higher waste heat recovery efficiency. The overall efficiency of the cycle with cyclopentane and R113 is 20.83% and 16.51%, respectively.

与传统的只回收发动机排气余热的热力循环系统相比，文中提出的构型其余热回收效率更高，当采用环戊烷为ORC工质时，循环系统的整体效率为20.83%；当采用R113为ORC工质时，循环系统的整体效率为16.51%。

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。

The small size of the conventional micro/small gas turbine results in blade path of small dimensions for the conventional turbine. The small dimensions have a deleterious effect on component efficiency. In the APGC operating under ambient pressure, larger specific volume results in large dimension of blade path and higher component efficiency, and the higher overall thermal efficiency also.

由于传统的微型和小型燃机体积小，通流部分尺寸相对窄小，造成燃机元件的效率不高；而环境压力下吸热燃气轮机循环在低于环境压力下工作，因此，流经透平和压缩机的体积流量增加，提高了通流部分尺寸，有助于提高元件的内效率，进而提高装置的循环效率。

According to an partial survey,95%of the de-sulfurizing equipments take the approach of hydro-de sulfurization , which is relatively efficient at disposing SO2 in the smoke and gas ,but this method is so futile at disposing SO3,the major corrosive parts in the smoke and gas, that only 20%of SO3 can be got rid of .

据不完全调查，我国有95%的脱硫装置采用湿法脱硫，湿法脱硫工艺对烟气中的SO2脱除效率较高，但对造成烟气腐蚀的主要成份SO3脱除效率并不高，仅20%左右。

Under similar operating conditions, the simulated horizontal belt washer has higher Norden efficiency factor than that of drum washer. Horizontal belt washer also has a high washing efficiency when operates at a low dilution factor.

3於相似操作状况下，模拟之水平带状洗桨机，具有较筒式洗浆机为高之诺顿效率因子，同时於低稀释因子下仍有极高之效率值。

This paper endogens carbon tax and subsidy two variables, discussing how to decide the optimal level of carbon tax and subsidy. The results of the research are obtained as the following:(1) price and capital subsidy which one is priority depend on the productivity of renewable energy capital, if productivity is high enough, then should adopt capital subsidy policy;(2) price and capital subsidy indeed exist trade-off and non-independent relationship;(3) renewable energy regulation ratio has negative effect on carbon tax, however has positive effect on price subsidy;(4) green certificate price increase will result in decrease carbon tax and price subsidy, but increase capital subsidy;(5) if the authority loose the environmental target, then should impose high carbon tax which maintains the environmental quality, but have ambiguous effect on subsidy policy;(6) increasing stability of renewable energy, then increase price subsidy, however, under budget constraint should decrease capital subsidy;(7) analyzing Taiwan's three wind power energy with different price subsidy, which can improve the technology of wind power energy. In another word, it can raise the capacity of wind power energy and reach the goal of renewable energy.

本文考量政府预算限制下，探讨最适碳税税率与补贴率订定之问题，获得如下发现：(1)发电量补贴与资本补贴对促进再生能源发展效果不一样，决定於再生能源资本的生产力，如果资本生产力足够高，则发电量补贴效果较佳；反之，则应优先采行资本补贴措施；(2)发电量补贴与资本补贴的确存在抵换而非独立关系，亦即在政府预算限制下，为促进再生能源发展，应将种种补贴措施整合考量，以最低行政成本达到再生能源发展目标；(3)再生能源管制配比与碳税税率及资本补贴率呈反向变化关系；而与发电量补贴呈正向关系；(4)绿色权证交易制度具促进再生能源管制目标达到之奖励效果，因此，绿色权证价格提高可降低发电量补贴及碳税税率，降低碳税对经济不利冲击效果；(5)政府如果采行较宽松环境目标，宜提高碳税税率，避免环境品质进一步恶化，然而，对发电量或资本补贴之影响效果不确定；(6)再生能源发电效率愈高，则应提高再生能源发电补贴，在预算限制下，应降低再生能源资本补贴；(7)透过台湾三座风力机组的实证分析，采取差异性发电量补贴，将可诱导较高效率风力机组的投资行为，提高整体风力发电效率，达到再生能源发展之目标。

Therefore, it can be safely concluded that the reason that top grafting shortening the juvenile period is mainly due to the enhancement in light energy conversion efficiency and photosynthetic efficiency.

由此可见，实生苗高接后增加了有效光合面积，提高了光能转化效率及光合作用效率，可能是高接可以缩短童期的缘故。

Milling groove machine is used in processing weaving trade in " pin plate " use privately cut machine tool, belong to the modular machine tool, this machine tool have 4 works position and 8 milling heads, can at the same time process 8 workpieces, have higher processing efficiency and processing precision, and can at the same time still realize needle groove and circular arc groove same work position, it surmounted the shortcoming of that machining process complex, processing efficiency low and process precision do not be in height of the processing of pin plate beforetime, so it have better application prospect.
