In the offshore-continental shelf area around China, there are rich petroleum deposits; there-fore offshore oil exploitation constitutes a substantial part of this country’s construction ofmodernizations. There is an enormous demand of large-size, sophisticated exploration, exploit-ation and transportation facilities for offshore development. Dalian shipyard has for a long timededicated itself to the development of offshore engineering facilities, and is one of the drilling

During the 2.nd Chinese Antarctic Research Expedition (CHINARE-2.), the atmospheric gas samples above the oceanic surface and near the surface were collected on the track for the scientific ship "Xuelong" and on Millor Peninsula of eastern Antarctica, respectively, using the Tedlar gas bags. Every day the sampling times were 10:00 and 2.:00 (local time), respectively. In the laboratory, high-precision measurement of the isotopic compositions for N2. in these gas samples was conducted using Thermo Finnigan MAT-2.3 Isotopic Mass Spectrometer with a fully automated interface for the pre-GC concen-tration (PreCon) of trace gases. The temporal and spatial variations of δ 15N and δ 18O in atmospheric N2. were analyzed. The mean δ 15N and δ 18O-N2. values above the oceanic surface were (7.2.±0.50)‰ and (44.52.0.52.‰, respectively. From 30°N to Antarctica, the δ 15N (6.05‰―7.88‰) linearly increased with the rate of about 0.01‰ with the latitude while the δ 18O (43.05‰―48.78‰) showed a large fluctua-tion. The δ 15N negatively correlated with air temperature and N2. concentration, and slightly positively correlated with δ 18O. The summertime variations of δ 15N and δ 18O-N2. appeared the same trend on Millor Peninsula of eastern Antarctica. They significantly positively correlated with each other and negatively with N2. concentration. The δ 15N and δ 18O-N2. at different sites averaged (7.42.0.35)‰ and (44.69±0.49)‰, respectively, slightly higher than those above the oceanic surface, significantly higher than those of atmospheric N2. in the low-latitude regions of Northern Hemisphere. The predominant factors affecting the spatial variations of δ 15N and δ 18O values were also discussed. The isotopic data given in this study can help to investigate the global and regional N2. budgets.

- The phenomena of stress concentration of tubular T joints are investigated widely in the present paper. After investigation of many experimental data of stress concentration factor of T joints and numerical computation of 100 examples of T joints subjected to axial load and out plane bending load, the interaction curves between stress concentration factor and geometric parameters α, β, γ, τ of tubular T joints are provided. According to these curves and in comparison with experimental data, some tables for designers are performed. The reliability analyses of these tables are also presented here.
