| 1 | On the adjacent-vertex-strongly-distinguishing total coloring of graphs显示文摘For any vertex u∈V(G), let TN(U)={u}∪{uv|uv∈E(G), v∈v(G)}∪{v∈v(G)|uv∈E(G)}and let f be a total k-coloring of G. The total-color neighbor of a vertex u of G is the color set Cf(u)={f(x)|x∈TN(U)}. For any two adjacent vertices x and y of V(G)such that Cf(x)≠Cf(y), we refer to f as a k-avsdt-coloring of G('avsdt'is the abbreviation of'adjacent-vertex-strongly- distinguishing total'). The avsdt-coloring number of G, denoted by Xast(G), is the minimal number of colors required for a avsdt-coloring of G. In this paper, the avsdt-coloring numbers on some familiar graphs are studied, such as paths, cycles, complete graphs, complete bipartite graphs and so on. We proveΔ(G)+1≤Xast(G)≤Δ(G)+2 for any tree or unique cycle graph G. | ZHANG ZhongFu CHENG Hui YAO Bing LI JingWen CHEN XiangEn XU BaoGen | 2008 | Science China Mathematics2008，51，3： | 74 |
| 2 | Characteristics of Long Air Gap Discharge Current Subjected to Switching Impulse显示文摘Measuring the pre-breakdown current of long sparks in air is important for investigating the discharge mechanism.Since the breakdown of long air gaps is conducted by a series of streamer-leader processes,the corresponding current signals cover a bandwidth of 0 to more than 20 MHz.Measurement accuracy of the current from the high voltage side is affected by the displacement current and impulse electromagnetic interference.In this paper,a coaxial current sensor with a DC bandwidth of 74.45 MHz is developed.A displacement current-restrained electrode structure is proposed to reduce the equivalent capacitance between the current sensor and the ground over 30 times.Combined with the digital optical fiber synchronous acquisition unit,a current measurement system for long air gap discharge is established.For the purpose of the UHV system’s external insulation optimization design,the discharge current waveform of a 6 m rod-plane air gap under positive switching impulse voltage with 250µs and 1000µs time to crest is obtained.Discharge images and stressed voltage are combined to analyze the continuous feature of a current waveform under critical time to crest impulse and discontinuous feature under long front duration impulse.For the purposes of a lightning protection study,the current waveform of a 10 m rod-plane air gap is subjected to negative switching impulse.Finally,the pulse characteristics of the current corresponding to the single channel and branching stepped negative leader are discussed. | Yishi Yue Hengxin He Weijiang Chen Junjia He Chuanqi Wu Xiangen Zhao Feng Huo | 2015 | CSEE Journal of Power and Energy Systems2015，1，3： | 13 |
| 3 | Computing payment for ecosystem services in watersheds: An analysis of the Middle Route Project of South-to-North Water Diversion in China显示文摘Payment for ecosystem services (PES) has attracted considerable attention as an economic incentive for promoting natural resource management recently. As emphasis has been placed on using the incentive-based mechanism by the central government, rapid progress on PES research and practice has been achieved. However PES still faces many difficulties. A key issue is the lack of a fully-fledged theory and method to clearly define the design scope, accounting and feasibility of PES criteria. An improved watershed criteria model was developed in light of research on PES practices in China, investigations on the water source area for the Middle Route Project of South-to-North Water Diversion and ecosystem services outflows theory. The basic principle of assessment is the direct and opportunity cost for ecological conservation and environmental protection in the water source area deduct nationally-financed PES and internal effect. Then the scope and the criteria methods were determined, and internal effect was put forward to define benefits brought from water source area. Finally, Shiyan City, which is the main water source area for the Project of Water Diversion, was analyzed by this model and its payment was calculated. The results showed that: (1) during 2003-2050, the total direct cost and opportunity cost would reach up to 262.70 billion and 256.33 billion Chinese Yuan (CNY, 2000 constant prices), i.e., 50.61% and 49.38% of total cost, respectively; (2) Shiyan City would gain 0.23, 0.06 and 0.03 CNY/m3 in 2014-2020, 2021-2030, and 2031-2050, respectively. | Zhengju Dong Yan Yan Jing Duan Xiao Fu Qingrong Zhou Xiang Huang Xiangen Zhu Jingzhu Zhao | 2011 | Journal of Environmental Sciences2011，23，12： | 12 |
| 4 | 儿童状态社会创造性的跨文化研究:基于中美文化的比较显示文摘从中国和美国中部地区选取小学儿童236人,采用状态社会创造性开放问卷和教师领导方式结构式问卷考察了儿童状态社会创造性的文化差异及其与教师领导方式的关系。结果表明:(1)总体上,美国儿童在社会性问题解决中表现出较强的流畅性和变通性等创造性思维品质,但中国儿童表现出较强的适当性、有效性和冒险性等社会适应和人格状态;(2)状态社会创造性总体上存在着国别与年级之间的交互作用,美国的四年级儿童状态社会创造性得分显著高于五年级儿童;(3)教师领导方式的各个维度均不存在显著的预测作用。中美儿童的状态社会创造性既有相似之处又有不同之处。 | 谷传华 张冬静 Yeh Hsueh Xiangen Hu | 2015 | 心理与行为研究2015，13，2： | 2 |

| 7 | 儿童特质社会创造性的跨文化研究:基于中美文化的比较显示文摘从中国和美国中部地区选取小学儿童236人,采用特质社会创造性问卷、自尊量表(SEI)和父母养育方式简式量表(S-EMBU)考察了他们特质社会创造性的文化差异及其与自尊和父母养育方式的关系。结果表明:中国儿童特质社会创造性高于美国同龄儿童;总体上自尊和父母养育方式均可以预测儿童的特质社会创造性,但自尊水平对中国儿童社会创造性的预测作用较大,而父母养育方式对美国儿童社会创造性的预测作用较大。结合不同的文化背景,提高儿童的自尊,改善父母养育方式,有助于提高儿童的社会创造性。 | 谷传华 张冬静 Yeh Hsueh Xiangen Hu | 2014 | 中国特殊教育2014，，4： | 1 |

| 11 | Protection of ±500 kV HVDC Double-circuit Converter Station from Lightning Induced Overvoltage显示文摘In order to obtain reasonable schemes of arrester in converter stations, the arrester scheme of 'Xiluodu-Guangdong HVDC ± 500 kV double circuit transmission' project against lighting induced overvoltage, which was designed according to the main principle of lightning protection in converter station, is discussed. A calculation of the lighting induced overvoltage in Zhaotong converter station un- der various operation modes is performed with ATP-EMTP software, then the surge arrester configuration of the converter station is decided, and the arrester protection schemes of smoothing reactor and neutral line are studied. It is concluded that additional protection is necessary because of the relatively large gap between protected disconnecting switch and arrester of metallic return transfer bus. Plus, the smoothing reactor (SR) arrester near the valve hall could be removed to improve the scheme’s economic performance. | DONG Manling YUAN Zhiyong LI Tianwei ZHAO Xiangen ZHANG Jiaxin HE Junjia | 2013 | 高电压技术2013，39，8： | 1 |
