The technology of combined heat and power generation on renewable energy (CHP-RE) is of posi- tive significance for energy saving, environment improving and green economy. Solar energy, geothermal energy and biomass energy are the most potential renewable energies for large scale CHP. This paper intro- duced the CHP-RE development at home and abroad, and compared several main CHP-RE technologies. The CHP on geothermal energy is mature, while the CHP on solar energy, which can be used widely, is still in the stage of project demonstration and technology development. The photovoltaic-thermoelectric CHP, based on the comprehensive utilization of solar spectrum, will be the next hot topic in future. The CHP-RE cannot be promoted without smart grid. The sustainable community will lay the foundation for large scale utilization of CHP-RE, in which the needs of local energy are satisfied first and excess electricity can be sold to smart grid.

Under the great development of Chinese economy, the recent number of cars being sold and on road has increased year after year in China. Meanwhile, there are huge issues concerning the en-vironmental quality, the energy supply, and noise levels. To address the issues, this paper intro-duces a technology utilizing flat-plate model of the automobile tail-pipe energy harvesting (ATEH), which recovers energy from the automobile pipe exhaust gas. This technology can reduce a car’s gasoline consumption. The ATEH is designed, and is composed of two hot boxes and three cold boxes. The exhaust gas flows through the hot boxes, while the cooling water flows through the cold boxes. Thermoelectric units are assembled between one hot box and one cold box. To test its roadside performance, the ATEH was integrated with a pickup truck. The installed unit is located between the three-way catalyst and the muffler. Based on the automobile roadside test, maximum output power of the ETEG was 300 W per unit. To some extent, the ATEH can meet the normal electricity demand of a car.
德國統一社會黨的新方針與科學研究機關的任務

科学通报 , 1954,
Abstract: 1958年10月31日至11月1日,德國統一社會黨在萊此錫召開了一個高等教育會議。在這次会上,审查了黨和政府所給與科學及各高等學校的任务是怎樣完成的,並且討論了對當前在這方面最重大的問題所應採取的措施。在這次討論中,德國統一社會黨中央委員會科學高等教育部部長庫尔特·哈格尔作了題为“新方針與科學研究機關的任務”的總結報告。從這個報告中,我們可以看到在新方針照耀下,德意志民主共和國科學的發展,獲得了充分優越的條件,科学在为和平服務,为改善勞動人民的物質文化生活服務;相反的,在西德,在美國壟斷資本和他們所豢養的阿登納政府的統治下,科學受到了沉重的束縛和殘暴的摧避,西德科學日益淪為帝國主義屠殺人民和加强剝削勞動人民的工具。從這個報告中,我們也可以了解到德國統一社會黨的科學工作政策,了解到德國科學工作者如何團結在黨的周圍,為了反對法西斯的陰謀破壞,為了建立一个統一的、獨立的、民主的、愛好和平的德國,進行着堅决的鬥爭。了解這一切,對我國科學工作者是很有帮助的。這里刊載的是庫尔特·哈格尔的報告的摘要。

Abstract:
提出了一种基于支持向量机分类器的线条图像语义主题自动发现方法。首先对训练图像进行分块,在对图像子块进行聚类后,得到由聚类中心构成的类集合;从每幅训练图像的注释文字中提取所有名词构成关键词集合。其次,对未标注的测试图像进行同样分块处理,计算子块与每个关键词的相关性,得到每个子块的标注词集合。最后,计算每个关键词在各个子块标注中出现的次数,取出现次数最多的关键词作为图像的语义主题。实验结果表明,所提出的方法对于线条图像的语义主题自动发现是有效的,具有比较好的性能。
A semantic topic discovery approach of the line image, based on support vector machine, has been proposed in this paper. Firstly, the training images are divided into non-overlapping sub- blocks with same size. After clustering image sub-blocks, we obtained class set generated by cluster centers, and extracted all nouns from text annotation of each training image in order to obtain a keyword set. Secondly, the un-label testing image is also divided into non-overlapping sub-blocks as same as training images, we calculated the correlation between the sub-block and each keyword, and a keywords set for each sub-block may be obtained. Finally, the number of each keyword appearing in the each sub-block is calculated, we let the keywords with maximum to occurrences number be the semantic topics of the line image. The experimental results confirm that proposed automatic semantic topic discovery approach for line image is effective and has good performance.

Abstract: The influence of staggered distance on the failure of floor strata in double-longwall mining on the confined aquifer is local and temporary. After longwall mining having reached a certain scale, the failure depth in floor strata depends on macroscopic parameters of mining technology and geological conditions. The current and ultimate failure depth of the floor strata does not change due to the magnitude of mining staggered distance (5~30 m). Based on the mining geological conditions of a practical double longwall mining panel, a rational staggered distance of double-longwall faces is proposed to be within 10m, by means of observing the changes of in-situ abutment pressure and 3D coupled numerical modeling of fracture in floor strata.
