This paper is aiming to estimate the mutual influences of the stack cooling performance with the operation modes of the thermal management system for the hydrogen fuel cell *** heat capacity of the thermal management system was measured by varying the operating modes such as stack cooling heat exchanger only（Mode 1）,stack cooling and electric devices cooling heat exchangers（Mode 2）,and stack cooling and electric devices cooling heat exchangers with an operation of the condenser（Mode 3）.As the results,performance of the thermal management system（TMS） at Mode 3 decreased up to 34.0%,compared with the result of the Mode *** compared between real road test and laboratory test using cooling module tester with respect to heat dissipation rate of the radiator,error ratio based on real road test data was 1.83% at 70 km/hr of driving speed and 3.58% at 100 km/hr of it,*** cooling module tester was thought to be reasonable to predict performance characteristics under real road driving conditions.

This study facilitates the scalability of as-built data from an earlier street level to underground transportation sites from the life-cycle perspective of urban information maintenance. As-built 3D scans of a 6 km street were made at different time periods, and of 3 underground Mass Rapid Transit (MRT) stations under construction in Taipei. A scanned point cloud was used to create a Building Information Modeling (BIM) Level of Development (LOD) 500 as-built point cloud model, with which topographic utility data were integrated and the model quality was investigated. The complex underground models of the transportation stations are proofed to be in correct relative locations to the street entrances on ground level. In the future the 3D relationship around the station will facilitate new designs or excavations in the neighborhood urban environment.

Tropical Cyclone Research and Review 2012年第3期1卷 277-292页

This study examines the long-term variations of tropical cyclone(TC) frequency and intensity in the South China Sea(SCS) and the vicinity of Hong Kong from 1961 to 2010 based on the best track data of four main weather agencies in the western North Pacific, namely the Hong Kong Observatory, China Meteorological Administration, Regional Specialized Meteorological Center Tokyo and Joint Typhoon Warning Center of the United States. To account for the discrepancy in the best track data between agencies, the maximum sustained wind speeds are standardized to the 10-minute average before data analysis. Moreover, a sensitivity assessment based on three different data scenarios is also conducted to study the uncertainty in trend analysis due to the discrepancy in the datasets from various agencies. The results show that, likely modulated by the El Ni?o Southern Oscillation and the Pacific Decadal Oscillation, there exist strong inter-annual and inter-decadal variations in the TC frequency in the SCS and the vicinity of Hong *** the long-term trend, all dataset/scenario combinations depict a decrease in the TC frequency in the SCS and the vicinity of Hong Kong during the study period, but the trend is not statistically significant at 5% level for most of the datasets. As for the TC intensity, the discrepancy between weather agencies remains very substantial even when the difference in the wind speed averaging period is accounted for. The large differences in the available datasets do not allow for a reliable detection of the long-term trend of the TC intensity in the SCS. The study of the TC impacts on Hong Kong reveals that there is no significant trend on the TC-induced extreme rainfall in Hong Kong. The extreme high winds associated with TCs within 500 km range of Hong Kong have no significant trend at Waglan Island(offshore island) while those of the urban station at Kai Tak have a signifi-cant decreasing trend.

DDT and Endosulfan are persistent organic compounds which have been prohibited and their use has been limited in agricultural activities due to their toxicity, persistence and bioaccumulation potential. The use of DDT in fumigation campaigns against endemic diseases transmitted by vectors of malaria and dengue was prohibited in Carmen Island, Campeche, Mexico since 1995. In the surroundings of Sabancuy Lagoon, many and diverse agricultural activities are carried out and it is a common practice to use organ-chlorine pesticides as endosulfan. In order to know the levels of these compounds in this area, a sediment sampling campaign was carried out in ten sampling points randomly located within the Sabancuy Lagoon, Campeche and considering one reference sampling point located 2 km away from Sabancuy Lagoon within the Mexican Gulf. Three metabolites were identified in sediments samples belonging to DDT’s family: (4,4’-DDD;4,4’-DDE;4,4’- DDT) and Endosulfan’s family (Endosulfan I, Endosulfan II y Endosulfan sulfate). Higher concentrations in DDT’s family were found for 4,4’-DDD, followed by 4,4’-DDE and 4,4’-DDT. Endosulfan’s family, showed the following order for concentrations: Endosulfan II > Endosulfan I > Endosulfan sulfate. Mean concentration for S-DDT and S-Endosulfan in Sabancuy Lagoon sediments was twice higher than those found in other studies carried out in Términos Lagoon, Campeche, Mexico in 2002.

This study was performed to compare storm surges/tide simulated by the regional and coastal storm surges/tide forecast system （RTSM （regional tide/storm surges model）, CTSM （coastal tide/storm surges model）） using two different inputs from weather models （RDAPS （Regional Data Assimilation and Prediction System） and KWRF （Korea Weather and Research Forecasting）） during two typhoons that occurred between 2007 and 2008. Both the RDAPS and KWRF are the operational weather forecasting system in kmA （Korea Meteorological Administration）. The horizontal resolutions of RDAPS and KWRF are 30 and 10 km, respectively. The storm surges/tide was hind casted using sea wind and pressure fields of two Typhoons which was approaching Korean Peninsula. The CTSM using input from KWRF simulate very well the storm surges/tide pattern in the complex coastal areas. The result showed that the storm surges by the coastal storm surges/tide model with high resolution input was in well agreement with the observed sea level occurred by high tide and storm surges in the coastal areas.

本文详细分析了西太平洋Ogazawara断裂带（OFZ）附近海山浅剖剖面（3—7kHz）和地形特征。OFZ断裂带是太平洋中较为独特的断裂带之一，在其周围发育了多个较老的海山（如麦哲伦海山和Dutton洋脊上的海山），该断裂带沿北西一南东走向，宽150km，长600km，且具有右旋移动特征。对海山的浅剖剖面声学特征分析之后，根据浅剖剖面的声学特征和反射连续性，底基构造和海底形态，将底基声学特征划分为9个具体类型：（1）清晰反射（类型Ⅰ-1，Ⅰ-2，Ⅰ-3），（2）不清晰反射（类型Ⅱ-1，Ⅱ-2，Ⅱ-3），（3）双曲线反射（类型Ⅲ-1，Ⅲ-2，Ⅲ-3）。类型Ⅰ-2为远洋沉积，表现为较细的间歇性盖层，当底流较强时沉积可能发生在地形隐蔽区域，而类型Ⅰ-1远洋沉积分布较为连续和广泛。OFZ断裂带侧翼裂谷带的形成可能受先前火山活动时期存在的转换断层的影响，而Pigafetta盆地的ItaMaiTai海山仅受火山建造的影响和控制。岩墙侵入和火山活动形成的海山侧翼裂谷带在块状坍塌过程中起着重要作用。块状坍塌过程包括了沿山顶边缘的大量断裂和火山活动，滑塌／崩塌，碎屑流和浊积流，它们可能受断裂活动，火山作用，岩墙侵入和海山演化各个时期风化作用的控制和影响。

Carbon dioxide (CO2) is the primary anthropogenic greenhouse gas (GHG). India’s CO2 emissions are expected to increase 70% by 2025. Geologic carbon storage (GCS) offers a way to reduce CO2 emissions. Here we present the results of a search for the most cost-effective GCS opportunities in India. Source-Sink matching for large and concentrated CO2 sources near geological storage in India indicates one very high priority target, a fertilizer plant in the city of Narmadanagar in Bharuch District of Gujarat Province, India that is km from old oil and gas fields in the Cambay Basin. Two pure CO2 sources are km from deep saline aquifers and one

Three-component Ocean Bottom Seismometers, portable land stations and marine air gun seismic sources were used to carry out an onshore-offshore deep seismic profile in northeastern South China Sea. This profile, orientated in NNW-SSE, was as long as 500 km and perpendicular to the strike of regional tectonics. The offshore data were processed in Taiwan Ocean University using a number of available software and the onshore data were analyzed in South China Sea Institute of Oceanology by new-written programs and public software. Preliminary results show that the seismic data are in good quality and contain rich information of deep structure. Seismic phases, e.g. Pg, PmP and Pn, are identified in the offset range 5～220 kin, which will provide an important dataset for the deep crustal structure and oil-gas basin evolution studies of this region.
