含盐溶液汽液平衡的状态方程法研究c单一溶剂盐溶液蒸汽压的测定及关联
李伯耿,寿,朱自强
化工学报 , 1986,
Abstract: 用静态-双沸点仪比较法测定了不同温度下CaCl_2-H_2O,CaCl_2-CH_3OH,CaCl_2-C_2H_5OH,KAc-H_2O,KAc-C_2H_5OH五种溶液的蒸汽压,共132个数据点.以CCOR状态方程关联实验数据,相对平均误差为±0.42%.所得的状态方程参数可用于含盐溶液汽液平衡的计算.
气相色谱法定量分析α-乙酰-γ-丁内酯
潘奉华,朱京科,寿,孙昊
色谱 , 1996,
Abstract: ?Butyrolactone, α-acetyl-γ-butyrolactone and solvent in reaction mixtures from the preparation of α-acetyl-γ-butyrolactone were determined by gas chromatography.The analytes were separated at 190℃ on a 1m ×3mm stainless-steel column packed with silanized 102 white support coated with polydiethylene glycol succinate and monitored with a thermal conductivity detector. The relative error was less than 2.5%.

广东高州水库库区不同开发类型小流域的水土流失比较分析
黎华寿,世明
中国生态农业学报 , 1993,
Abstract: 本文通过面上调查和定点取样分析,对粤西高州水库库区三个不同农业开发类型小流域的水土流失进行了比较分析。结果表明,格苍小流域地势陡削,比良垌、军屯两小流域更不利于保持水土。由于该流域以热带亚热带竹林和针阔叶混交林为主的植被保护较好,能因地制宜发展立体林业、建立林农复合农业生态系统,故水土流失远小于良垌和军屯,农业经济效益也优于良垌和军屯。
北极东北航道LNG运输经济性与前景分析
巧云,寿建敏
大连海事大学学报 , 2016,
Abstract: 在分析北极资源的基础上,结合我国天然气供需、进口状况和北极航道通航环境分析,对通过北极东北航道和通过传统航线运输LNG的经济性进行比较,并从航线里程、航次、运输成本三方面论证北极东北航道LNG运输的经济性.采用敏感性分析方法探究航运环境各因素变化对北极航道航运成本的影响,展望了未来发展前景. 研究表明:东北航道航程明显缩短,但全年航次增加不多,运输成本无突破性降低.
Based on the analysis of resources in the Arctic regions, the economy of LNG transportation through the Arctic Northeast passage was compared with that of the traditional route according to natural gas supply and demand, import conditions and navigation environment of the Arctic routes. The economy of LNG transportation through the Arctic Northeast passage was discussed in consideration of routes, voyage or flight number, and transport cost. By using sensitivity analysis method, the influences of shipping environment changes on cost of the Arctic Northeast passage were discussed, as well as the prospects. Result shows that the Northeast passage distance shortens obviously, but the year voyage increase is not obviously, and the transportation costs reduce no largely.

蜕皮激素对昆虫生长及生殖过程的调控
周娇,翁强,
应用昆虫学报 , 2013,
Abstract: 蜕皮激素、保幼激素及神经激素在调节昆虫生长及生殖方面起到重要的作用。本文从蜕皮激素的合成过程、其活性形式20羟基蜕皮酮的作用模式、蜕皮激素与保幼激素的相互调节机制这三个方面综述了蜕皮激素在昆虫生长及生殖过程中的调控作用。
