活性炭载体的超声波处理对Pt／C催化剂活性的影响分析

通过对活性炭载体进行不同条件的超声波处理获得了具有不同表面化学性质的载体，使用比表面积（BET）、酸碱滴定等技术手段对载体的物理化学性质进行了表征。将经过超声波处理的活性炭载体制备成Pt／C催化剂，并将催化剂直接用于催化反应，考察了活性炭载体的不同超声波处理条件对Pt／C催化剂性能的影响。实验发现，活性炭载体经过超声波处理后，表面灰分含量、pH值和中孔孔容有较大的变化；使用经过60min超声波处理后中孔孔容较大的活性炭作为载体制备的Pt／C催化剂，在催化加氢反应性能测试中显示了最高的催化活性。在此基础上，就活性炭载体的超声波处理对Pt／C催化剂活性的影响进行了讨论。

Kirkpatrick于1982年认识到固体粒子退火过程和组合优化问题有相似性，从而提出了模拟退火算法，并从数学上已证明了模拟退火算法可以取得全局最优解。相比之下，传统的最优化法只能求局部最优值。在计算物质平衡方程时，存在很多不确定的参数，给精确计算带来了一定困难。因此，本文引入模拟退火算法求解物质平衡方程。

Balancing energy and environment: The effect and perspective of management instruments in China

The rapid growth of Chinese economy has tremendously stimulated the expansion of energy consumption. The structure of energy consumption in China is featured with the coal domination. Air pollution is becoming increasingly severe. As a result, we are confronted with the extremely arduous task to balance energy consumption and environmental protection. In order to coordinate the relationship between energy consumption and environmental protection in a strategic way, this paper analyzes comprehensively the instruments, effects and perspectives of energy-related environmental management. Meanwhile, this paper illustrates the barriers and challenges facing the energy and energy-related environmental management in China, and suggests a priority strategy of management instrument, mainly composed of energy-saving, optimization of energy structure, promulgation of environmental standards, advance in environmental technologies, internalization of environmental costs, establishment of a public benefit fund and adoption of a Renewable Portfolio System.

A FISH technique for simultaneous detection of fluorescent R-band and in situ hybridization signals]

BACKGROUND: Because of serious adverse effects of centrally acting antitussive agents, is necessary to find new drugs with cough-suppressing activity. Medicinal herbs are a potential source of polysaccharides with high antitussive efficiency and on the other with minimal side effects. AIM: The study was to assess the antitussive action of mixture of a polysaccharides (RL) and polysaccharide-xylan (XY), both isolated from above-ground parts of Rudbeckie fulgida var. sullivantii. The observed activity was compared to those of narcotic and nonnarcotic antitussive substances used in clinical practice. METHODS: Cough was evoked by mechanical irritation of the airways in nonanaesthetized cats with chronic tracheal cannuly. The plant substances were administered perorally in the dose of 50 mg per kg body weight. RESULTS: Results indicate, that administration of RL induced a suppression of the followed cough parameters from both areas of airways (total fall in cough parameters by 46.6%). Administration of xylan induced the fall in the followed cough parameters with more significant influence on the laryngopharyngeal area of the airways (total fall in cough parameters 48.2%). CONCLUSION: Administration of RL and xylan did not achieve the effect of codeine, but had a more intensive antitussive effect than the peripherally acting droprozine and prenoxdiazine.
