楼宇冷热电联供系统成本分摊方法研究

多产品系统的成本分摊问题，是运用热经济学方法分析能量系统的关键环节之一。这里分析了现有的热电联供系统成本分摊的主要方法，指出了各种方法的实质，提出一种成本分摊的新方法——“价格系数法”。分别运用3种方法分摊了楼宇冷热电联供(BCHP)系统热电之间的成本，并进一步计算制冷部分的成本。实际BCHP系统的分析表明，“价格系数法”将联供带来的好处合理分配给冷电热三部分，有效解决了三联供系统的成本分摊问题。     

Energy and Exergy Analysis, and Thermoeconomic Performance of a BCHP System

Building cooling, heating and power (BCHP) systems should play an important role in achieving the goals of energy efficient use and environment protection in China. It will make big sense when this type of system shows a good performance energetically and economically. An on-site BCHP system being the first in the country was installed and put to use five years ago. As the first step to evaluate the project, com~tations were made based on thermodynamic and themoeconomic theories to evaluate the system on full load and off-design conditions in summer. Discussion and analyses are made mainly in terms of exergetic efficiency and costs of unit amount of useful exergy produced in this paper.     

Optimization of Load Assignment to Boilers in Industrial Boiler Plants

IntroductionThe optimization of load assignment among differentunits in a power system has been a long lasted subject sincethe middle of the 20th century. It benefits power systemsdirectly. The first major progress was the principle ofcoordination of incremental fuel costs presented by E. E.George, H.W. Page, and J. B. Ward [1,2]. A number ofresearchers contributed to the theory and practices of thecoordination of incremental fuel costs in those decades. Itis well wor…     

Survivin与辐射关系的研究进展

Survivin又称为存活素，是IAPs家族中分子量最小但抗凋亡能力最强而倍受关注的基因，由美国耶鲁大学的Ambrosini等在1997年利用效应细胞蛋白酶受体-1（Effector cell Protease Receptor，1，EPR-1）的eDNA在人类基因组的杂交筛选中分离并克隆出来。IAPs是一类结构相关的细胞凋亡抑制蛋白，目前发现8个成员，     

小波分析在太阳辐射神经网络预测中的应用研究

通过小波变换将太阳辐射数据序列分解到不同的时频域上，并对每一频域分量建立一个递归BP网络模型；然后用网络模型对各频域分量进行预测，将各预测结果进行代数叠加，从而得到太阳辐射的预测结果。为体现近期预测结果在精度上的相对重要性，在递归BP网络的权闽值修改算法中，引入了折扣系数法。最后，通过对上海太阳日总辐射的预测实例表明，该方法在预测太阳辐射时是可行的。
