    在湍流局地平衡假设下,建立 了齐次湍能输运方程封闭模型(HKE),并在平板边界层的两种经典流动中加以检验,给出HKE 封闭下的流速、湍流动能和湍流混合系数剖面的形式解。结果表明,HKE可以避免在流速剪 切为零时的无湍流混合问题,其解与Laufer湍流实验吻合,因而HKE模型比混合长理论有更 合理的内涵。文中还给出HKE封闭的浅海动力学模型,以湍应力和水位梯度力的平衡为运动 的基本受力平衡,进行了模型的量阶分析和运动分析:当阻尼频率和运动频率同量阶时,惯 性运动不可忽略;在潮振荡占优的浅海中,对流非线性相对于惯性运动为小量;当阻尼频率 足够大时,科氏力项相对于湍应力也可能为小量。

Abstract  Based on the hypotheses of local turbulent equilibrium, a new turbulen t closure model based on the using the Homogeneous K-equation(HKE) is developed  in this paper. Applying this model to solving the flow between two parallel fla t planes with the upper one moving homogeneously and to a symmetrical flow with  a constant gradient, the profiles of velocity, turbulent kinetic energy and turbulent viscosity are solved. The result obtained from the symmetrical flow is in  agreement with Laufer's experiment. HKE can be used to close the fluid dynamic.  Moreover it can avoid the fatal disadvantage of Mixing Length Hypotheses when solving problems with zero velocity shear. It suggests that HKE is superior to the  closure model using Mixing Length Hypotheses. A hydrodynamic modle for coastal  seas closed by HKE is proposd. Taking into consideration the nonlinear effect of  turbulence, the movements in a coastal sea are analyzed. Turbulence presents a  wide field of research in the coastal sea.

The basic balance in a coastal sea should be between vertical turbulent diffusio n and the water level gradient. When the movement frequency is in the same order  as the damping frequency, the inertial effect cannot be ignored. In a coastal s ea where tide is the dominant movement, the advective nonlinear term is small re lative to the inertial effect. When the damping frequency is large enough the Co rilios term can also be ignored relative to turbulent stress. For the kinetic boundary condition at the sea surface, rigid lid hypotheses are fit for circulatio n but not for the tidal oscillation.

Key words  turbulent closure;local turbulence equilibrium;homogenous turbulent kinetic energy transport equation;hydrodynamic model of the coastal sea

Abstract  Sub-tropical high is one of the main causes of summer S STA in the Yellow Sea and the Bohai Sea. In this paper, an off-shore SSTA numerical forecasting model was employed to simulate the SST in this area. According  to the summer climat e features of this area, a typical sub-tropical high process was constructed to  further quantitatively analyze the cause of SSTA in summer. The SST variation caused by different factors in the position of sub-tropical high centre and the  positions near it was given as well. The test showed that in the region dominate d by sub-tropical high, short-wave radiation was the main cause of the SST inc rease, surface warm water convergence played a secondary role.

Abstract  An external ulcerative disease, which frequently occurred  in Japanese flounder, Paralichthys olivaceus, now cultured in artificial pro pagation facilities along the coasts of Shandong, China, has caused mass mortali ties in recent years. Histopathological study showed that the diseased fish had  hyperaemia and hemorrhage in the ulcerated muscle tissue as well as decoloration  of the skin, especially among fry and juveniles. Many ciliates were found not only on the body surface but also inside the skin, scale pocket, fin, muscle, per itoneal cavity, blood and characteristically brain of the Japanese flounder. The  ciliate was a pathogen to flounder and was identified as Paralembus digitiformis, a marine facultative parasitic scuticociliatid ciliate. Meanwhile, a bact erium Moraxella cuniculi was also purely isolated from the heart of the naturally infected flounder and also proved to be a pathogenic bacterium for flounde r by experimental infection.

The Calculation for the High-Speed Mass of Rock Overlayby Low-Speed Medium In  the Tidal Zone of the Shallow Sea

Xue Rongjun  Li Jinshan  Tang Yong

(Ocean University of Qingdao, Qingdao, 266003)

Abstract  There are a number of high-speed masses of rock close to the bedrock  overlaid with a low-speed layer of the Quaternary under the bottom of the shallow sea. They would make the engineering geologic survey very difficult in these  areas and even impossible. However, it is sometimes very important to determine  the location, the depth, the length and the thickness of the high-speed masses  of rock. According to the principle of seismic refraction method, the formulas o f the depth and the thickness of the high-speed masses of rock are established  using seismic refraction wave reversed and unrepressed time-distance curve and  seismic refraction wave raypath theory in this paper. As long as the velocity of  the medium and the refraction wave reversed and unrepressed time-distance curve are known, we can obtain information about the high-speed masses of rock.

Abstract  In comparison with normal adaptive digital beamforming that only uses  the second-order statistics of signals, a Higher-order cumulantbased adaptiv e digital beamformer (HCAB) is discussed in the paper. The HCAB utlizes higher- order cumulants to construct a fourth-order cumulant matrix to estimate the steering vector of the desired signal. Because higher-order cumulants include more  statistical information, the HCAB beamformer is not very dependent on the manif old of the array, easily adaptive to the error, and able to track moving objects . The results of simulation indicate its good performance.

Abstract  The study status and research achivements on non-uniform sediment are  analyzed and presented systemically in this paper based on a comprehensive review of the hiding and exposing action, incipient velocity, flume experiment and t ransport characteristics of non-uniform sediment that have been conducted over  the past 50 years. By means of a research method of vectorial mechanics, all kinds of forces acting on a particle of non-uniform sediment in hiding and exposing states are studied respectively. General vectorial equations of incipient velo city on an arbitrary bed-surface in the above two cases are derived respectivel y. Next the above mentioned vectorial equations are discussed for different angles of bedsurface, and the calculated results of incipient velocity for onedimensional equation in exposing state are verified with experimental data.
