Abstract:
本文通过采用熵权理论和灰色定权聚类法相结合的企业电力能效评估模型,对企业电力能效的评估方法进行研究与应用。文章先对电力能效评估模型建立指标权重的过程进行了系统分析,又通过灰色定权聚类法对能效综合评估模型的建模过程进行分析,从而建立了一种对企业电力能效进行系统评估的方法。该方法不仅科学地处理了指标权重在定量化过程中主观判断的问题,而且以企业聚类系数最大化为出发点,充分利用了各指标数据已有的客观信息及隐含的灰色特性,对指标进行综合治理,得到各个企业的电力能效状况,从而为企业的节能降耗提供很好的依据。本文最后还以三家企业为评估对象,对三家企业的电力能效进行了详细的建模分析,验证了该方法的可行性。
By using the enterprise power efficiency evaluation model based on entropy theory and grey fixed-weight clustering method, this article studies and applies a method of enterprise power efficiency evaluation. Firstly the author analyzes the process of how the index weight of power efficiency evaluation model is established, and then analyzes the process of modeling the comprehensive power efficiency evaluation based on grey fixed-weight clustering method. Accordingly, a method to systematically evaluate the enterprise power efficiency is established. This method not only has scientifically dealt with the problem—subjective judgment in the process of quantifying the index weight, but also makes full use of the index data of the existing objective information and the implicit grey characteristics to maximize the enterprise clustering coefficient. Meanwhile, this method can also comprehensively process the various indexes, and figure out the precise power efficiency of each enterprise to provide a good basis of saving energy and reducing consumption for the enterprise evaluated. Finally, this article, taking the evaluative object of three companies as basis, models and analyzes these three companies’ power efficiency, and verifies the feasibility of the method.

 [PDF]

Abstract:

表皮生长因子受体(epidermal growth factor receptor: EGFR)在细胞信号转导中发挥了重要作用,调节细胞的增殖、分化与迁移。EGFR与多种癌症密切相关,这使其成为一个理想的抗肿瘤药物靶点。本文对EGFR的结构生物学及计算生物学的研究进展做一综述。通过结构生物学家的不懈努力,已经对EGFR的三维空间结构有了较为清晰的认识。计算机模拟是研究生物大分子动态过程的重要手段之一,可以在EGFR静态结构的基础上,模拟其在配体诱导的激活过程中发生的大尺度、长时程的动态构象变化。对EGFR的结构及其分子内部运动的研究,有助于揭示其发挥生物学功能的分子机理,为抗肿瘤药物的设计开发提供指导。
Epidermal growth factor receptor (EGFR) plays a critical role in the network of signal transduction, and regulates cell proliferation, differentiation, and migration. EGFR is implicated in different kinds of cancers, which makes it an excellent target for anti-tumor therapy. This review considers structural and computational studies of EGFR, and their impact on our understanding of EGFR function. With continuing efforts of biologists, many high-resolution structures of different regions in EGFR, which include the extracellular region and the intracellular tyrosine kinase do-main, have been solved. Starting from these structures, computer simulation techniques enable us to investigate large length-scale and long time-scale conformational changes during the EGFR activation. All the studies will be helpful to reveal the molecular mechanism in EGFR regulation, and provide valuable knowledge for developing anti-cancer drugs.

墙面太阳辐照的理论计算与模式估计——以上海为例

地理学报 , 1987,
Abstract: 倾斜面和墙面的太阳辐射和日照状况对于农林生态、建筑环境工程以及城市气候研究具有重要意义。为了充分利用水平面日照与日射的丰富资料以得到倾斜面和墙面相应变量的细致分布规律,本文将理论计算与模式估计相结合的方法具体应用到一个平原城市(上海)。在倾斜面直接辐射计算中,本文以倾斜面与水平面天文辐射月值的比值(R_b)取代各月代表日的(R_(bo))在倾斜面日照时间的估计中,本文提出利用水平面日照百分率的简单方法。在倾斜面辐射与日照的时空分布规律方面主要突出其随方位与随季节(月份)的变化。 作为例子,本文计算分析了上海市每月各方位墙面上的天文辐射与可能日照时间,对相应的实际日照时间进行了估计。并在计算给出的(R_b)值的基础上,利用散射辐射各向同性与非各向同性模式研究了上海各月墙面直接辐射与总辐射随方位的变化特征。

我国自然植被生产力功能和地带性结构的气候耦合

地理学报 , 1996, DOI: 10.11821/xb1996S1007
Abstract: 本文用北京模型研究了我国自然植被净初级生产力(NPP)的分布,给出了各植被区NPP的大致范围,并用图解模型揭示了气候因子、植被生产力功能和地带性结构之间的耦合关系。结果表明,净辐射和辎射干燥指数的函数组合既是确定植被NPP的主导因子,又能在很大程度上说明植被地带性结构的有序排列。在研究植被分布和分区时引入NPP指标可以更简捷地阐明有关规律。另外,如将净辐射表示为生物温度或潜在蒸散,北京模型则可用于气候变化对植被影响的研究,还可与Holdridge的生命带方法进行比较。
