The result showed that the assemblages of phytoplankton in Chukchi Sea can be divided into three ecological groups： Arctic-boreal group, distributed mostly in northeastern ice-edge where the depth is more than 2 000 m and affected directly by Arctic Ocean; Boreal group, distributed in shelf-break ice in the center water where the depth is less 100 m; Eurythermal group, mainly distributed in the south which exchanged with North Pacific water through Bering Strait. The species diversity, cell density and distribution variability of phytoplankton among stations were great different. The range of phytoplankton density among stations was 1.6 × 10^3- 90 680.2 × 10^4 cells/m^3, and the ranges of diversity index and evenness index among stations were 0.07 - 0.87 and 0.33 - 3.82, respectively. Principal components analysis （PCA） showed that temperature and salinity had made important roles in the distribution of phytoplankton in the Chukchi Sea. Furthermore, the different influences of the variant water regimes, and the extremely dynamic physical nature of the drifting pack ice （e.g. packing, breaking up and melting ） introduce short-term variability into the water conditions that no doubt affect the phytoplankton distrubition.展开更多

Soil P was analyzed using Bray-1 （BP）, Olsen （OP）, and Mehlich-3 （MP） methods as agronomic tests, and using Fe-oxide impregnated filter paper （FeP）, anion-exchange resin membrane （RP）, and water （WP） as environmental tests. There were linear relationships between soil P extractable with all the tests evaluated. The regression coefficients, R^2, ranged from 0.8164 to 0.9409 between each two of the agronomic soil test P, and ranged from 0.4702 to 0.8990 between each two of the environmental soil test P, when the three soils were considered separately. When soil test P was analyzed across all the three soils, the highest regression R^2 was found between OP and MP （0.7940） amongst agronomic soil test P, and between FeP and RP amongst environmental soil test P （0.8842）. While all of the three agronomic soil test P was linearly related to each of the environmental soil test P across the three soils, strongest relationships were found between OP and environmental soil test P. Agronomic OP may be adopted as an analytical tool for environmental prediction of soil P.展开更多

The paper analyses those representative regional environmental discharge data by the systemic main-clements analysis module, speedily discoveries and explains the regional environmental major control factors in the studying region. According to the special points of social, economical and environmental in the region, the paper gives out the improvement policies of regional environmental quality and practicable environmental engineering disposed project. This research not only indicates the development direction of the urban environmental management, but also builds up a main frame of the urban environmental planning. This paper and its relative works provide an efficiently digital management tool for the urban regional environmental management and explore the feasible method and mode for the improvement of urban regional environmental quality.展开更多

This paper presents the fundamental principles of the analyses. The key to the analyses is the determination of roof subsidence and the nonlinear relationship between diffusion coefficient and subsidence. This paper discusses these problems and determines the coefficient for Pingdingshan mining district, with which several profiles are predicted. It is found that the predicted profiles are coincident with the corresponding field profiles.展开更多

The paper aims at exploring the use of the comic elements that is not without purpose. Instead through this incorporation of farce, linguistic humor, witty repartee and exaggeration, the holistic vision of life is obtained which was earlier compartmentalized by the Greeks and Roman playwrights. Comic elements including slapstick humor, the singing of songs, and certain character portrayal are discussed as techniques employed at the hands of the playwrights to reflect over the real historical milieu of their respective times, yet giving a boost to realism as a theory and a practice. This is a qualitative study based upon hermeneutic theory of textual analysis. The paper establishes the similarities in Bernard Shaw＇s and Anton Chekhov＇s employment of comical elements as well as the difference between their essential purposes in generic transgression. Although the two writers have their roots in different countries, their humorous portrayal of various issues is seen to be similar. From the microanalysis of these plays, the same comic strains can be traced out in modern drama at macro level that will enhance the implication of this research paper. This paper therefore concludes that comic and tragic elements are not antagonistic rather complimentary to each other.展开更多
