Among the economic crops, pachyrhizus leaf had the most remarkable treating effect, the COD treating capacity per day per unit area was 4.01g, that is, a 50% treating rate; the BOD treating capacity was 1.15 g, that is, a 35% treating rate; the TP treating capacity was 0.23 g, that is, a 16% treating rate; the TN treating capacity was 1.87 g, that is, a 74% treating rate; however, the treating effect decreased as the total amount of pollution entering this system increased by raising the water volume, which was mainly owing to the relatively short hydraulic retention time.

由水质试验结果显示，本系统所选用的作物处理生活污水成效极佳，优於一般湿地选用的植物，以及河滩地原生草种型态，其中以地瓜叶的处理成效最为显著，每日单位面积COD去除速率为4.01 g 、处理效率达50﹪；BOD去除速率为1.15 g 、处理效率达35﹪；TP去除速率为0.23 g 、处理效率达16﹪；TN去除速率为1.87 g 、处理效率74﹪，而以加大水量的方式，增加进入本系统之污染总量，其处理成效减低，主要原因受到水力停留时间较短影响，未来可以增加处理面积、水力停留时间加长、提高原水浓度为后续之研究方向，以达到增加本系统处理成效之目的。

When researching the producer's behavior,such as factor input and output efficiency,using product function or cost function,researchers frequently ignore the economic inefficiency and assume that the productor can attain the production possibility frontier.

通常采用生产函数或成本函数研究生产者行为时，一般默认生产者总是在生产可能性边界安排生产，而忽略了由于产出的经济无效率所造成的偏差，这种偏差最终会影响要素替代弹性、要素最优配置及产出效率的准确测度。本文采用面板模型的三要素成本函数循环参数估计法，通过施加规模报酬不变的假设，估算了辽宁省工业部门二类行业的相对技术无效率、配置无效率程度及要素间的相对价格扭曲，并计算了资本、劳动、能源要素间的交叉替代弹性。

China"s stock markets had made a great progress after 14 years" development, their functions of financing, resource disposal, liquidity providing and company management bettering had got well exerted. This means the function efficiency had been improved.2.As for the market structure, operating method and regulations conditions, the participants" structure and quality had been increased fast, the transaction cost had been greatly reduced, and issuing and liquating method had become more fair and effective, the relative laws and regulations had been better and better, the operation efficiency had been improved.3.Compared with other stock markets, China"s stock markets" indexes had performed a good random walk property, which means that the pricing efficiency had been improved.4.Compared with other advanced markets in the world, by and large, on the basis of China"s rapid improvement on economy recently, China"s stock markets" efficiency was relatively low.

根据分析研究，本文的主要结论和观点如下： 1、中国股市14年来的发展取得了重大进步，其融资、资源配置、提供流动性以及改善公司治理等功能都得到了良好的发挥，功能效率程度得到提高； 2、从股市结构、运作机制和体制环境来看，股市主体的结构和质量有了快速提高，交易成本大大降低，发行和流通方式更加公平、有效，各项法律法规也不断得到完善，其运作效率程度得到提高； 3、与世界主要股票市场相比，中国股市指数的随机游走特性逐渐良好，说明14年来，中国股市定价效率得到了快速提高； 4、中国股市与世界先进市场相比，综合来看，考虑到中国股市的发展背景和近几年国民经济的快速发展，其效率还是较低的。

The radiation by non-thermal plasma can accelerate formaldehyde thansform and make an increase of 29.61% in depurated efficiency. The surface modification makes no obvious difference in depurated efficiency. The chemical modification avails formaldehyde reduction and ACF coated with nano- TiO2 is the best of all that can enhand the depurated efficiency to 94%. The great influence of parameters on depurated efficiency , such as applied voltage and reaction time , shows that an increase in either applied voltage or reaction time enhance formaldehyde conversion.

研究结果表明：低温等离子体辐射能促进甲醛净化，可使其净化效率提高29.61%；表面改性对净化效率没有明显影响；化学改性有利于甲醛净化，其中负载纳米TiO2改性方案最佳，其净化效率高达94%；电源电压和反应时间等参数对净化效率也有较大影响，电压越大，时间越长就越有利于甲醛的去除。

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。
