Two hybrid processes including ozonation-ceramic membrane-biological activated carbon （BAC）（Process A） and ceramic membrane-BAC （Process B） were compared to treat polluted raw water. The performance of hybrid processes was evaluated with the removal efficiencies of turbidity, ammonia and organic matter. The results indicated that more than 99% of particle count was removed by both hybrid processes and ozonation had no significant effect on its removal. BAC filtration greatly improved the removal of ammonia. Increasing the dissolved oxygen to 30.0 mg/L could lead to a removal of ammonia with concentrations as high as 7.80 mg/L and 8.69 mg/L for Processes A and B, respectively. The average removal efficiencies of total organic carbon and ultraviolet absorbance at 254 nm （UV254, a parameter indicating organic matter with aromatic structure） were 49% and 52% for Process A, 51% and 48% for Process B, respectively. Some organic matter was oxidized by ozone and this resulted in reduced membrane fouling and increased membrane flux by 25%-30%. However, pre-ozonation altered the components of the raw water and affected the microorganisms in the BAC, which may impact the removals of organic matter and nitrite negatively.

As the successor of CBERS-01, CBERS-02 was launched successfully on 21October 2003 and transmitted its first downlink data the next day. According to the OBT (On Board Test) outline, CRESDA cooperated with CAST and many remote sensing organizations in China in implementing the test of the satellite payloads, ground processing system and data application. In this paper, the test is briefly illustrated in three parts: Ⅰ. Satellite Parameters Test (especially the test for payloads), Ⅱ. Payload Image Quality Assessment, and Ⅲ. Data Application Assessment. The results of the test show that the image quality of CBERS-02 is much improved over CBERS-01 and will continue to play a more important role in the society and economic development of China.

The main payload on CBERS-01/02 of China-Brazil Earth Resources Satellite (CBERS) is a push-broom CCD camera with moderate spatial and radiant resolution. Because at lab the data for calibration at satellite assembly stage were unable to be collected, and also because the onboard calibrator after launch was in a different state from imaging, the calibration of CCD image got a series of difficulties involved. In practice, two methods are used in the processing on the ground station: One is extracting calibration data by statistics from the image itself, and the other is the method of histogram match. It was proved that the latter can calibrate the image much better, because it can remove the effect of unstable response of the camera largely and also can overcome the nonlinearity of the camera basically by using Look-Up Table (LUT) calculated from histogram statistics of different temporal images. Considering the problems of CBERS-01, a lot of calibration tests were done before the launch of CBERS-02, in which a set of lab coefficients for relative calibration was formulated after the data collection by using integration-hemisphere in the stage of satellite assembly test. During the on-orbit test, it was found that the calibration result from such coefficients was not satisfying, especially there being response difference between 3 detector arrays, which was attributed to the unstable dark currents of the CCD camera. This paper comes up with a statistic method to remove such response difference. In this method the middle detector array was used as reference to find the response differences of adjacent similar features between these arrays and it was proved to have a broad adaptability.

1957年2月,毛泽东在最高国务会议上做了《关于正确处理人民内部矛盾的问题》的报告。如何结合半个世纪的风风雨雨和变化着的实际,站在新世纪的制高点上,认真研讨与审视毛泽东的人民内部矛盾学说,是一个具有重要理论与实践意义的课题,同时也是一个颇有争议和难度、极具挑战性的课题。本文论述了毛泽东人民内部矛盾学说的贡献与局限,分析了毛泽东正确处理人民内部矛盾的思想未能在实践中落实的原因,提出逐步用“社会矛盾”的概念替代“人民内部矛盾”的表述,分析了现阶段社会矛盾的主要表现和特点,阐述了构建和谐社会是当代中国的新主题,并进而认为,从50年前提出正确处理人民内部矛盾,到今天提出构建社会主义和谐社会,体现了国家政治生活主题的变化和党的执政理念的升华。

在中国马克思主义哲学发展史上,艾思奇以其"三个第一"的开创性贡献奠定了十分重要的历史地位。这主要体现在,艾思奇的《大众哲学》是马克思主义哲学大众化的第一个成功范例;艾思奇第一次提出了哲学中国化即马克思主义哲学中国化的任务和命题;艾思奇主编的《辩证唯物主义历史唯物主义》是新中国成立后我国通用的第一本马克思主义哲学教科书。以艾思奇的《大众哲学》为起点,中国马克思主义哲学工作者在积极践行马克思主义哲学大众化的工作过程中,形成了《大众哲学》《通俗哲学》《新大众哲学》三部曲。这三部曲充分说明了中国共产党人对马克思主义哲学的高度重视,深刻体现了中国哲学工作者对马克思主义哲学大众化的自觉与执着。当前,推进马克思主义哲学中国化、时代化、大众化,建构中国马克思主义哲学话语体系,关键是要从实践和文化两个维度上进一步推进马克思主义哲学的中国化。只有坚持和发展马克思主义哲学的中国化,才能有力推动中国特色社会主义的伟大实践。
