Examples
- However , its greenhouse warming potential ( gwp ) is relatively high among the newly developed hydroflourocarbons ( hfcs ) , which seems to be an obstacle for the furtherance of the use of r - 134a , especially in european countries
然而，在新近发展的hfcs类物质中，它的gwp值相对较高，这就阻碍了它的进一步使用，特别是在欧洲国家。 - Patents on removal of olefins in hcfcs and hfcs at home and abroad are gathered up and classified , principles and characteristics of every method are reviewed , the author also points out that adsorption method is an imporant research trend in refining technology of hcfcs and hfcs
摘要概括了国内外氢氯氟烃和氢氟烃中烯烃脱除方法的专利文献，评述了各种方法的原理、特点，并指出吸附法是当前氢氯氟烃和氢氟烃精制技术的发展趋势之一。 - The corn refining industy was estabished in 1848 in america . the world war stimulated the development of corn refining and the corn refiner got much more economic profits . the comprehensive utilization of corn was realized and a variety of modified starch were developed before 1950s in america . after 1960s , the corn refiners in america created lots of bioproducts from corn starch by the fermentation . first of all , the hfcs which has been a popular product at present was largely produced . moreover , many organic acids and sugar , alcohols were produced as chemical materials . the corn refiners in the america are focusing on developing new corn refining products which can take the place of petrol products
美国玉米加工业始建于1848年,第一、二次世界大战刺激了玉米加工业的发展,并使美国玉米加工企业获得了大量的经济利益.本世纪50年代前,美国玉米加工业就已实现了综合利用,并开发了多种变性淀粉. 60年代以后实现了从淀粉到生物技术产品的转化.首先,玉米高果糖浆实现了工业化生产,并成为目前玉米加工业的主要产品.此外,以葡萄糖为原料,生产有机酸、醇等化工原料.目前,美国加工业正致力于开发替代石油制品的玉米深加工产品 - The peng robinson cubic equation of state ( pr eos ) is used to calculate thermodynamic properties of frequently used refrigerants ( r12 , r22 , r502 ) and prospective alternatives refrigerants ( r134a , r152a , r125 ) and mixed - refrigerants ? the result of using cfc and hfcs refrigerants is contrast to the result of mixed - refrigerants in ideal single - press circle at lower evaporating temperature
在单级和双级两种不同制冷循环下，研究了不同制冷工质在变蒸发温度及变冷凝温度的循环性能。本文采用状态法? pr方程计算常用的制冷工质( r12 、 r22 、 r502 ) 、有希望的替代物( r134a 、 r152a 、 r125 )和混合工质的热力学性质。
