CFB (Circulaiing Flued-bed Boiler), which could desulphurize by adding the lime stone in boiler, was adopted in the project of petroleum coke taking the place of oil; IGCC was adopted in coal to gas project; PC+FGD, such as limestone/plaster wet type desulfurization, liquid spray flue gas desulfurization, electron beam flue gas desulfurization and sprayed dry type desulfurization etc., was adopted in the other projects of thermoelectricity. Desulfurization inside boiler needs less running expenses but high investment and lower desulfurization efficiency.

Gingerols in ginger oleoresin were separated by AB8 macroporous adsorption resin and silica gel column chromatography. The samples were characterized by the gas chromatography-mass spectrometry method.The peak area normalization method was used to determine the relative percentage of the components and the rate of accumulation of gingerol was determined by contrasting with gingerol standard samples. The results showed that gingerols was concentrated on the 3rd and the 4th parts.

A two-dimentional isothermal transient full film and part film EHL model has been established, which is used to analyze lubricational behavior of cam-tappet pair of valve train. Using mulit-gird method, the oil film status during intake duration could be investigated with the consideration of dynamic effect. The influences of surface roughness are also taking into account in the part film model.

The paper attempts to design and development a new type of hydraulic pump. It is the design of combining the advantages of sucker rod pump and rodless botttom hole pump, without pumping rod,and depends on the hydraulic system on the ground providing the impetus. The paper uses the pump Swabbing Principle to design the main parts of the pump structure and size, analyses and calculates the up down stroke of the piston and the switching process of pump valve, uses the finite element method to analyse the main force summing element and check intensity, and designs a ground hydraulic control system to match it. Considering the need of deep mining, salvage equipment is designed. The design shows that there is feasible and reliable to realize the exploitation underground using the new hydraulic pump. The design idea in this paper enlightens the rodless botttom hole pump production in the future and other similar issues.

本文尝试一种新型液力泵的设计和开发，它的设计思想是结合有杆泵和无杆泵各自的优点，取消抽油杆，依靠地面液压系统提供动力，本文从抽油泵抽汲原理出发，设计了抽油泵主要部件的结构和尺寸，对上下冲程柱塞的运动规律和泵阀启闭过程进行分析和计算，使用有限元法对主要零件进行了受力分析和强度校核，并设计与之配套使用的地面液压控制系统，考虑深井开采的需要，一并设计了打捞装置，为理论上实现了这种新型液力抽油泵井下开采的可行性和可靠性做了一些基础的工作，本文的设计思路对今后无杆泵采油等类似问题的研究做了有益的尝试。

The fatty oil from the seeds of M. cochinchinensis was extracted with petroleum ether, and the saponification was carried out with potassium hydroxide. The unsaponifiable matter was isolated and purified by silica gel column chromatography, and the structures of their constituents were elucidated by means of IR, MS, 1H-NMR, and authentic chemicals.

Based on the fact that during the forming of lubricating film, entraining effect is plays a leading role while squeezing effect only has a minor, suggestions on designment of cam-tappet pair and selection of lubrication oil are presented.

针对油膜的建立过程中卷吸效应为主、挤压效应为辅的状况，对凸轮-挺柱润滑副的设计及车用润滑油的选择提出了建议。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
