海拉尔盆地地层水特征与粘土矿物转化和赋存的关系

海拉尔盆地地质条件及其复杂,开发难度大,本文将油藏地球化学中地层水研究与粘土矿物成岩转化研究相结合,指出了地层水特征与空隙中粘土矿物及其他矿物成岩转化和赋存的某种相关性,对储集层地质学研究很有助益,对勘探开发一体化研究提供了该方面重要的科研依据。

Determination of the degree of cure under dynamic and isothermal curing conditions with electrical impedance spectroscopy

This article presents a new methodology for the quantitative determination of the progress of the curing reaction of a thermosetting resin, using the results of electrical impedance spectroscopy. The method is an extension of the use of the imaginary impedance maximum as a reaction progress indicator and is based on the demonstration of a close correlation between the reaction rate, as measured by conventional differential scanning calorimetry, and the rate of change of the value of the imaginary impedance spectrum maximum. Tests on a commercial aerospace epoxy resin under both isothermal and dynamic heating conditions with calorimetry and impedance spectroscopy have demonstrated the validity of the method and set the accuracy limits involved. This technique can be used as a real-time online control tool for thermoset composite manufacturing. © 2003 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 42: 146–154, 2004     

Investigation of thin-film electroluminescent structures on rough subsrates

Results of experimental investigations of the volt-brightness characteristics, frequency dependences of brightness, and the directional radiation pattern of electroluminescent MSDM, MSCM, and MSDCM emitters, where M stands for the first transparent and second nontransparent electrodes, S is a semiconductor, D is a thin-film dielectric, and C is a silicone-based composite liquid dielectric with a powdered segnetoelectric filler, developed on conventional “smooth” and rough glass substrates are presented. It is shown that electroluminescent structures on rough surfaces have a brightness approximately two times higher than that of similar structures developed on a “smooth” substrate.

岩芯筒压入地层的塑性力学问题

摘要首先从库仑定律出发导出了地层介质塑性流动条件。其结果类似于一般塑性力学中的Tresca,Mises条件。其次列出了轴对称地层塑性流动的微分方程组,并推出了其简化近似方程。最后提出了简化方程的特征线解法,并举例说明。     

太白山国家森林公园游客结构及行为特征研究

基于实地问卷调查资料,通过对太白山国家森林公园的游客结构及其行为特征分析,指出其主体客源为省内大中城市居民,游客年轻化的趋势较明显且以中低收入者为主,旅游活动是以基本层次的旅游观光居优;该旅游景区的自然风光使近80%游客的美感体验得到满足、且游客感应最深的是清新空气、山地气候及森林植被等,相对较差的是宗教文化;此外,四成多的游客对旅游服务质量不满意.针对上述结果,就太白山国家森林公园开拓客流市场、促销定位、促使其可持续旅游业发展提出理性建议.
