Particle size distributions and organic-inorganic compositions of suspended particulate matters around the Bohai Strait

Laser in situ scattering and transmissometry(LISST) significantly improves our ability to assess particle size distribu-tion(PSD) in seawater, while wide-ranging measurements of the organic-inorganic compositions of suspended particulate matters(SPM) are still difficult by using traditional methods such as microscopy. In this study, PSD properties and SPM compositions around the Bohai Strait(China) were investigated based on the measurements by LISST in combination with hydro-biological parameters collected from a field survey in summer 2014. Four typical PSD shapes were found in the region, namely right-peak, left-peak, dou-ble-peak and negative-skew shapes. The double-peak and negative-skew shapes may interconvert into each other along with strong hydrodynamic variation. In the upper layer of the Bohai Sea, organic particles were in the majority, with inorganic particles rarely observed. In the bottom layer, SPM were the mixture of organic and inorganic matters. LISST provided valuable baseline information on size-resolved organic-inorganic compositions of SPM: the size of organic particles mainly ranged from 4 to 20 μm and 40 to 100 μm, while most SPM ranging from 20 to 40 μm were composed of inorganic sediment.     

Rosenblueth方法在深基坑抗隆起可靠度分析中的应用

由于岩土参数具有很大的不确定性,在深基坑抗隆起稳定性分析中高安全系数并不一定安全。为此,提出了深基坑抗隆起稳定性可靠度分析方法,基于Rosenblueth方法开发了相应计算程序,研究了土性参数c, 变异性对可靠指标的影响,并通过实例分别运用可靠度和安全系数分析方法分析深基坑抗隆起稳定性。结果表明:可靠度分析方法具有科学性和合理性,同时体现了Rosenblueth方法在复杂功能函数中进行可靠指标计算的优越性。

Method and application of comprehensive knowledge discovery

This paper proposes the principle oi comprehensive knowledge discovery. Unlike most of the current knowledge discovery methods, the com-prehensive knowledge discovery considers both the spatial relations and attributes of spatial entities or objects. We intro-duce the theory of spatial knowledge ex-pression system and some concepts inclu-ding comprehensive knowledge discovery and spatial union information table (SUIT). In theory, SUIT records all in-formation contained in the studied ob-jects, but in reality, because of the com-plexity and varieties of spatial relations,only those factors of interest to us are se-lected. In order to find out the compre-hensive knowledge from spatial databas-es, an efficient comprehensive knowledge discovery algorithm called recycled algo-rithm (RAR) is suggested.     

Experiment of near surface layer parameters in ice camp over Arctic Ocean

Estimates of near surface layer parameters over 78°N drifting ice in ice camp over the Arctic ocean are made using bulk transfer methods with the data from the experiments operated by the Chinese Arctic Scientific Expedition in August 22-September 3,2003.The results show that the net radiation received by the snow surface is only 3.6 W/m2,among which the main part transported into atmosphere in term of sensible heat and latent heat,which account for 52% and 31% respectively,and less part being transported to deep ice in the conductive process.The bulk transfer coefficient of momentum is about 1.16×10-3 in the near neutral layer,which is a little smaller than that obtained over 75°N drifting ice.However,to compare with the results observed over 75°N drifting ice over the Arctic Ocean in 1999,it can be found that the thermodynamic and momentum of interactions between sea and air are significant different with latitudes,concentration and the scale of sea ice.It is very important on considering the effect of sea-air-ice interaction over the Arctic Ocean when studying climate modeling.     

Detection of a primitive hydrogen cloud

Our identification of absorption systems in the quasars OQ 172, [4,6], has reliably determined one such at z = 3.3528 supported by the hydrogen lines L-L. Analysis shows it to be a primitive hydrogen cloud formed after the big bang. Assuming no broadening due to damping, we found a Doppler width b = 55 km/s and a column density 1g N_H = 14.66 from the curve of growth.

This paper develops a method which can be used to assist aerial navigation by determining the spatial position and posture of the aerial photographic plane. After the method, aerial images match known DEM to capture the spatial position and posture. Some aerial images and terrain data are used to testify our method. Compared with those of analytic and stereo mappers, the results by our method are correspondent to real measurements well.
