Result The three strains all produced the AHL signal molecules; the strains FML05-land FML05-2 produced two types of AHLs at least and the N-3-oxo-octanoyl-homoserine lactone was the predominant signal molecules. The production of siderophore and proteinase in FML05-2 were reduced by co-incubation with AHL degrader strain.

The self-centering mechanism design of bipolar endoprosthesis has advocated the use of offset centers of rotation between the inner and outer joint bearing surfaces to generate a self-centering moment on loading to prevent impingement of polyethylene rim and stem neck or cup fixed at wrong place. The design was used popularly, but the function of self-centering mechanism was discussed in very few papers. Three bipolar endoprosthesis were evaluated: UNIQHIP system, UHR system, and AML system.

但是由于凹凸棒石孔道直径小于大多数分子及水合离子的直径，除少数简单分子和离子外，多数分子和离子都不能进入凹凸棒石孔道，而且凹凸棒石选择性吸附水分子，因而在多数情况下，凹凸棒石对吸附质的吸附不是内表面吸附，而是外表面吸附。并且外表面吸附是胶体和离子交换吸附。本文阐述了凹凸棒石的孔道直径、吸附选择性、体系pH 值及凹凸棒石和蒙脱石胶体颗粒的互相作用对凹凸棒石吸附性能应用的制约。

Therelationship between the turbulent kinetic energy and its dissipation rate,whichis widely used to parameterize the dissipation rate in turbulence closure models,is found to hold well for both reversing and rotating flows,but with differentcoefficients.Microstructure profiling measurements at two comparative stations (a deepercentral basin and a local shelf break) in the stratified Yellow Sea are analyzed,with emphasis on tidal and internal-wave induced turbulence near the bottomand in the pyenocline.The water column has a distinct three-layer thermohaline structure,consisting of weakly stratified surface and bottom boundary layers anda narrow sharp pycnocline.Turbulence in the surface layer is controlled by thediurnal cycle of buoyancy flux and wind forcing at the sea surface.while thebottom stress induced by barotropic tidal eurrents dominates turbulence in thebottom boundary layer.The maximum level at which the tidally enhanced mixingcan affect generally depends on the magnitude of the tidal current,and it canbe up to 10-15 m in the Yellow Sea.This suggests that,in the deeper regionsof the shelf seas,turbulent dissipation and mixing are very weak at the levelsbetween the near-bottom tidally enhanced layer and the pycnocline.Therefore,these levels provide a significant bottle neck for the vertical exchanges.In theshallow regions,however,the tidally-induced turbulence can occupy the wholewater colum below the pycnocline.A quarter-diurnal periodicities of the turbulentdissipation rate and eddy diffusivity are found at different heights with evidenttime lag.In the relatively flat central basin,the pycnocline is essentially non-turbulent and internal-wave activity is very weak.Therefore,vertical fluxes acrossthe pycnocline decreased to molecular levels.In contrast,internal waves of variousperiods can be always found near the local shelf break.

对强层化季节黄海两对比性站位(分别位于中央海盆区与局地陆坡区)处层化、内波以及湍流混合特征的研究结果表明：1、强层化季节的陆架海水体一般呈现显著的三层热盐结构，在水体近乎混合均匀的上混合层与潮流底边界层之间为强跃层；2、近表层水体的湍流混合强度主要由海表浮力通量的日变化与海表风强迫控制，而在潮流底边界层内，潮混合是水体热量、物质、动量与能量垂直交换的主要机制；3、潮混合影响的深度由潮流大小决定，在黄海，一般可达10-15 m，因此，在水深较深的区域，在跃层与潮混合所至深度范围的上界之间存在湍流混合非常弱的区域，这显著抑制水体内物质的垂直通量，为物质垂直交换的瓶颈，而在水深较浅的区域，潮混合影响范围可至跃层底部，因此物质在跃层以下整个水体中混合非常均匀，当跃层内间歇性强混合发生时，可以产生显著的跨跃层物质输运；4、近底潮致强湍流耗散缓慢地向上传播，底上不同深度处垂直湍扩散系数也具有显著的位相差异，且二者均随时间呈现四分之一周日周期的变化；5、在地形较为平坦的中央海盆区，内波活动非常微弱，因此跃层内湍流混合非常弱，垂直扩散系数为分子扩散水平，跨跃层物质通量受到显著抑制，而在地形变化较为显著的局地陆坡区，内波活动非常活跃，除内潮的影响外，高频内波与内孤立波的影响也很显著，因此跃层内存在很强的间歇性强混合，内孤立波存在的区域，水体湍流混合显著增强。

Then based on CWMS, we propose a new method to enhance the resolution of seismic traces. Firstly, we divide the seismic signal into proper segments by Gabor molecule-windows adaptive to the signal, where each segment is regarded stationary, and then transform it into the Gabor domain. Secondly, we deal with the amplitude spectrum for each segment to expand the frequency band of the spectrum in the Gabor domain. Finally, taking inverse Gabor transform on modified time-frequency coefficients, we get the high-resolution signal.

然后基于变子波模型，提出了一种新的提高地震记录分辨率的方法：第一步，用自适应于地震记录的Gabor分子窗把地震记录恰当地划分成若干片断，每段内信号近似平稳，然后将地震记录变换到时间-频率域；第二步，在变换域对每个分子窗内信号的振幅谱进行处理以拓宽频带；最后把处理后的时间-频率域函数反变换回时间域得到提高分辨率后的结果。
