Two-dimensional electrophoresis (2-DE) is a valuable tool for the separation and characterization of pro-teins from complex biological samples. One of the main limitations of 2-DE is its inability to visualize low-abundant proteins, particularly in the presence of highly abundant proteins. In plasma, a few high-abundantproteins, such as albumin, immunoglobulins, lipoproteins, fibrinogen, et al, accounts for approximately 90%of the total protein. As protein expression within plasma has such a large dynamic range, attempts to detect traceproteins by increasing the total amount of plasma loaded onto a 2-DE gel, means excessive amounts of predomi-

Theoretical calculations of the ionospheric lower transition height(lTH),a level of equal O and molecular ion densities,were performed and compared with empirical models by Zhang et al.(1996).This paper represents a substantial extension of the prior work by including the AE-C data of ion composition analysis and by detailed quantitative studies of the lTH simulation,and by creating a new lTH empirical model based on our *** show that:(1) the calculated lTH,in general,is lowest near 11-13 lT and reaches the diurnal maximum after midnight(about 01-02 lT).The local time asymmetry becomes more evident in summer,when the time of minimum shifts to 16 lT.(2) The simulated lTH presents a dominant, semiannual variation during nighttime,and a pronounced annual variation during daytime.(3) The simulated lTH increases with solar activity at night and decreases by day, while the standard IRI option has an opposite tendency at night in summer and ***,the day-night difference of simulated lTH significantly increases with solar activity.(4) Both daytime and nighttime lTHs,tend to increase with the increasing geomagnetic activity Ap index, with a mean slope about 0.1455 km per Ap unit.(5) The diurnal variation of lTH is found to be more than 20 km,which is much larger than the seasonal variation under F107=100 and A=***,the diurnal and solar activity variations of lTH are more pronounced than its seasonal and magnetic activity variations.

为了探讨汶川MS8.0地震与温泉气地球化学特征之间的关系,分别在2008年6月、10月和2009年6月对中国西南地区四川西部32处温泉气进行了调查和样品采集,并针对三批次气样中的化学成分和He,Ne,C同位素比值进行了分析。数据显示,龙门山断裂带、鲜水河断裂带和岷江断裂带的温泉气中3He/4He,δ13CCO2含量在汶川大地震发生后明显增加。根据2008年6月测得的3He/4He最大值(7.42×10-6),预估在康定地区有高达62%的地幔氦增加进入到了温泉气中。随着时间的推移,地幔流体对温泉的贡献逐渐减少,但壳源气体,如有机物衍生出的CO2和CH4以及放射生成的He,其成分有所增强。温泉气的地球化学数据表明,在汶川MS8.0地震后,四川西部地区有更多的地幔流体迁移进入地壳中。
