一查政治观念。有无放松政治理论学习,理想信念滑坡,在世界观、人生观、价值观上有没有产生动摇,是否存在不读书不看报不关心政治的现象。二是整体观念有无严重的个人主义、自私自利,私欲膨胀,遇事先替个人打算,只顾眼前利益不顾长远利益;有无只讲待遇不讲奉献,只要报酬不思进取,过一天少两晌,整体观念淡薄等问题,三查责任观念。工作责任心强不强,[第一段] 相似文献

无名狗纪念碑 生理学家巴甫洛夫著名的条件反射理论是从狗身上试验出来的,因此,他要求为狗立一块纪念碑.1935年,一块"无名狗纪念碑"终于在列宁格勒实验医学研究所的大院里建成.碑上写道:"因长期对人友好、机灵、耐心和驯服,狗能多年乃至终生为实验者效劳." 相似文献

Remote Sensing Parameterization of Land Surface Heat Fluxes over Arid and Semi-arid Areas 总被引:5,自引:0,他引:5
Dealing with the regional land surfaces heat fluxes over inhomogeneous land surfaces in arid and semi-arid areas is an important but not an easy issue. In this study, one parameterization method based on satellite remote sensing and field observations is proposed and tested for deriving the regional land surface heat fluxes over inhomogeneous landscapes. As a case study, the method is applied to the Dunhuang experimental area and the HEIFE (Heihe River Field Experiment, 1988-1994) area. The Dunhuang area is selected as a basic experimental area for the Chinese National Key Programme for Developing Basic Sciences: Research on the Formation Mecbanism and Prediction Theory of Severe Climate Disaster in China (G1998040900, 1999-2003). The four scenes of Landsat TM data used in this study are 3 June 2000,22 August 2000, and 29 January 2001 for the Dunhuang area and 9 July 1991 for the HEIFE area. The regional distributions of land surface variables, vegetation variables, and heat fluxes over inhomogeneous landscapes in arid and semi-arid areas are obtained in this study. 相似文献

测井系统因带宽、调制技术及模拟传输等技术问题,数据传输速率慢且误码率高,难以满足煤层气测井的传输要求,为此设计了基于正交频分复用调制(OFDM)技术的测井电缆高速数据传输系统。该系统采用MAX2991/MAX2992芯片组实现了地面与井下调制解调器的全数字传输,在3~100kHz带宽、BPSK子载波条件下,5km四芯电缆传输速率可达到100Kbit,且误码率小于10-8。该系统在煤层气固井质量检测应用中,有效解决了原模拟系统中存在的全波列信号衰减大、易受干扰等问题,保证了全波列信号的无失真采集和传输,提高了对水泥环胶结质量评价的准确性。 相似文献
