均匀地

Pumping Systems—HPLC pumping systems deliver metered amounts of mobile phase from the solvent reservoirs to the column through high-pressure tubing and fittings. Modern systems consist of one or more computer-controlled metering pumps that can be programmed to vary the ratio of mobile phase components, as is required for gradient chromatography, or to mix isocratic mobile phases (i.e., mobile phases having a fixed ratio of solvents). However, the proportion of ingredients in premixed isocratic mobile phases can be more accurately controlled than in those delivered by most pumping systems. Operating pressures up to 5000 psi or higher, with delivery rates up to about 10 mL per minute are typical.

泵系统—HPLC 泵系统通过高压管路和设备将储液系统的流动相按设定的流量精确地输送通过柱子，最新的泵系统由一台或更多的计算机测量控制泵使得流动相组分能够按照程序变化改变比例，如有必要，可以进行梯度洗脱或混合均匀的流动相（i.e。，流动相可以是混合比例的溶液），然而，当操作压力达到或高于5000 psi，流速达到10ml/min的典型值时，预混合均匀的流动相各成分的比例就比泵控制的更精确。

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。

POMs and deys are still maintained integrallty.AFM exhibits the films is even.The thickness of each layer is about 1.25nm. The AFM images reflect that there are some protuberances on the outer surface layer of the film, which due to the aggregates of spherical structure PMo12. Cyclic Voltammograms reflects the redox potentials of dye in multilayer shifts towards more positive values than pure dye multiplayer which may be explained by charge transfer from dye to POM. Fluorescence spectra show that polyoxometalates caused the fluorescence decay of dyes, which maybe used as fluorescence sensors.

UV-VIS说明复合膜均匀生长； IR 光谱、XPS能谱研究结果表明，紫外光照前后，膜中多酸/染料分子间没有发生显著的光化学反应，各组分的结构仍然保持；原子力显微镜显示，膜的外表面是均匀的，每一个双层厚度大约是1.25nm，膜表面的隆起，可能是多酸阴离子簇堆积所引起；循环伏安测定结果表明，由于多酸阴离子的影响，有机染料的氧化还电位发生了正的偏移，反映出复合膜中染料分子与多酸阴离子间发生了荷移相互作用，导致染料分子失去部分电子而使氧化性略强；荧光光谱研究结果表明，多酸阴离子可以有效地引发荧光染料的荧光淬灭，这为多酸在荧光传感器方面的应用提供了有价值的信息。
