物理化学

Many industrial multiversities and specialist colleges have been established, strengthening some incomplete subjects and establishing new specialties, e.g., automation , atomic energy , energy resources , oceanography , nuclear physics , computer science , polymer chemistry , polymer physics , radiochemistry , physical chemistry and biophysics . A project for creating 100 world class universities began in 1993, which has merged 708 schools of higher learning into 302 universities.

同时，中国的高校还开设了许多新的学科，比如自动控制，原子能，能源，海洋学，核物理，计算机科学，高分子化学，高能物理，放射能化学，物理化学和生物物理学。1993年，中国的高等教育主管部门开始了一项名为创造100所世界级的中国大学的工程，把原有的708所大学合并为现在的302所综合性大学。

Once coupled at the filler interface the reactive Y component allows bonding to the polymer matrix by chemical reaction (grafting, addition, substitution) with active groups on the polymer and/or by physicochemical interactions. Y groups are selected to maximize compatibility with particular resin formulations.

一旦在填料界面发生上发生了偶联，反应性部分Y就会通过与聚合物上的活性基团的化学反应或者物理化学作用粘结到聚合物基体上。Y基团可以选择，以优化与特定树脂的相容性。

The variation of pH and conductivity of various phosphate solution with the solution temperature were obtained based on the physical chemistry theory and ionization equilibrium theory in electrolytic solutions, and be testified experimentally under radiation of ultrasonic wave. The pH was a linear function with the reciprocal of thermodynamic temperature, and the conductivity was a linear function with the temperature in phosphate solution.

Flocculation+0.45μm filter is selected as the pretreatment of the method proposed here.(9) A set of standard methods for ASMs COD characterization is suggested in the thesis and it advantages are:①Respirometry is adopted to measure RBCOD and SBCOD;②SI is determined from raw wastewater and so there is no influence of inert products;③Heterotrophic biomass in wastewater is measured;④The key instrument used in the standard methods-hybrid respirometer, has high automatic level and friendly user interface which simplifies the respirometry. So the suggested standard methods are practical.(10) According to the suggested standard methods, the influent COD of a wastewater treatment plant in Chongqing, China, is characterized.

9提出一套表征城市污水COD组分的标准化方法建议，其特点在于：①以呼吸测量作为RBCOD和SBCOD的测量方法，与以往以物理化学方法为主的做法有着本质区别；②对原水直接进行分析测试来获得SI组分，不受溶解性惰性产物的干扰；③考虑了污水中活性异养微生物组分的单独测量；④所依赖的核心仪器-呼吸测量仪具有很高的自动化程度和简单友好的用户界面，使原本复杂的呼吸测量实验及其结果的分析统计简单化，所建议的标准化方法具有很好的实用性。
