SOLAR Titan130压缩机组启动试运程序探究

1引言 燃气轮压缩机组由箱装体、进气过滤系统、排气系统、箱体通风系统、CO2灭火系统、滑油系统、等12个系统组成。本压缩机组采用净化天然气燃烧膨胀做功（透平）为驱动力,燃料气进站通过燃气处理撬将进气压力调整到2.6 MPa-2.8 MPa,最佳2.75 MPa,然后进入燃气轮机参与燃烧,提供动力支持。滑油系统的冷却采用撬外冷却系统,滑油冷却器配有一变频电机,首先采用是自然通风,     

HOMOPOLYMERS AND COPOLYMERS OF GLYCOLIDE AND LACTIDE

The homopolymerization and copolymerization of glycolide (GA) and lactide (LA) are des-cribed. The resulting polymers are characterized by differential scanning calorimetry (DSC),thermogravimetric analysis (TGA), 300 MHz proton nuclear magnetic resonance spectroscopy(NMR), infrared spectroscopy, and X-ray diffraction. The rheological properties of PGA andPGLA 910 are evaluated by shear experiments. The biodegradation has been studied in vivo. Theresults show that the polyesters can be absorbed by the muscles of rabbits after 60 days.     

PREPARATION AND CHARACTERISATION OF HYDROPHOBIC AND CATIONIC MONTMORILLONITE

INTRODUCTIONDuring mechanical pulping, lipophilic extractives, mainly comprising fatty acids, rosin acids and esters, are often released from wood chips into pr℃ess waters as dispersed colloidal substances. These colloidal substances must be controlled and maintained at a low level, otherwise they often cause various problems in the papermaking pr℃ess as well as in the final product, e.g. deposits on pr℃essing equipment [1,2]. Using highly cationic fixatives may help to reduce the pro…     

POETRY AND PLAIN SENSE

(A Note on the Poetie Method of T. S. Eliot) 1The poetic method of Mr. T. S. Eliot consists in a delicate symbolization ofFeeling. wide variations of Tone. a consists shift of Intention and an almost complete disregard for Plain Sense.2 This method is effected by composing poems ineight languages or more and by making them into mosaics of quotation fromother poets, some of them bad poets and others unknown to tile general reader.Many critics have thought that Mr. Eliot was not justified…     

ANCIENT AND MODERN PROBLEMS

There are two ideas of historical development. One represents it asa great whole evolving from the lowest cultural stages, if not ad infinitum,at least, ad indefinitum, and it is presumed that such a development iscontinuous; being so, history of humanity may be considered as thehistory of human progress or as an evolutionary process, the latter pointof view being now more popular, because of its "more scientific"character;. whether this evolution is simply linear or more complex, forinstance, …

THEORETICAL STUDY OF THE ELECTRONIC STRUCTURE AND CONDUCTING PROPERTIES OF POLYTHIIRENE AND POLYDITHIETE

The electronic structure and conduction properties of two kinds of polyyne derivatives with sulfur addition, palythiirene (PTI) and polydithiete (PDT) have been examined using ab initio Hartree-Fock crystal orbital method. Comparison of the results such as energy gap ? ionization-potential and electron affinity of PTI and PDT with those of polyacetylene (PA) indicates that both PTI and PDT have smaller band gaps than PA and they are better intrinsic semiconductors than PA. The π electron of sulfur atoms partly transport to conjugated polyyne chain.     

SYNTHESIS AND CHARACTERIZATION OF MONOVALENT AND MIXED-VALENCE COMPLEXES OF COPPER WITH 2-THIOURACIL

Five polynuclear monovalent and mixed-valence complexes of copper with 2-thiouracil were synthesized. They were characterized by the molar conductivity, electromc spectra, infrared spectroscopy, thermogravimetric and magnetic susceptibility measurements. Their coordination properties and tentative structures were discussed.     

PROMOTING SCIENCE AND TECHNOLOGY PROGRESS

Since China initiated the policy of reform and opening,Wuxi County has gained rapid development inindustry,agriculture and all the social undertakings.It was continuously appraised as the first of“OneHundred Powerful Counties of Comprehensive Strength of Rural Economics in China”for two years.So itis called the“First County in China”.In 1994,its GNP reached 17.5 billion yuan RMB and the gross in-dustrial and agricultural output value reached 65.04 billion.Benefiting from the industry,the agricultural
