较弱的

the market demand for the buckeye, but because the buckeye conventional breeding way is seed propagation, reproductive slower, plus the buckeye rate is low and seeds, seedlings to inactivation rate is weak, so the unearthed, reproduction rate low, difficult to meet the market demand.

市场对七叶树的需求量较大，但是由于七叶树的常规繁殖途径是播种繁殖，繁殖速度较慢，加之七叶树的结实率低且种子易失活，幼苗出土率较弱，所以，繁殖率较低，难于满足市场需求。

Temporal and spatialcorrelation of Soil moisture under vertical direction was affected by some factor such asmeteorology, land use and fertilization measures. All siol moisture in different layers hastemporal and spatial correlation when soil moisture fluctuates of surface layer becausestability, but influence ability of each factor is not the same. For example, meteorologyhas most strong impact on temporal and spatial correlation of soil water content.

在气象条件较稳定的情况下，不同植被覆盖和不同施肥措施下各土层含水量之间都具有较强的时空相关性，随着气象条件波动加剧，各土层土壤含水量的时间相关性和空间相关性都降低；植被因素相对气象条件对各土层含水量的时间自相关性影响较小，而对各土层土壤含水量之间的空间相关性影响较大，裸地和农田各土层土壤含水量之间的空间相关性相对林地和草地较弱；不同的施肥水平都削弱了土壤各土层含水量的时空相关性。

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。

Infrared spectroscopic analysis shows that the water glass is chemically adsorbed on the surface of titanaugite but this reaction is weaker between the water glass and ilmenite; hetero-coagulation will occur easily under weak acidic condition because of the opposite surface charge of ilmenite and titanaugite.

红外光谱分析表明：水玻璃与钛辉石发生化学吸附，而在钛铁矿表面吸附较弱；在弱酸性条件下，由于钛铁矿与钛辉石表面带异相电荷而容易发生异相凝聚，添加水玻璃使二者表面电位均显负电性，矿粒间静电斥力迅速增大，从而减弱矿粒间的异相凝聚。

The laboratory test on two-stage low-intensity magnetic separation and "medium- and low-intensity magnetic separation" technologies for the titanomagnetite was performed through selecting two-stage grinding-beneficiation technology based on -1.7mm coarse tailings abandoning. The results indicate that the technico-economic indexes of the two-stage beneficiation process based on "medium- and low-intensity magnetic separation" are better.

The average of quality of life is 52.98 ± 11.87. The quality of life among Lizu elderly people is not enough high. There may be considered three reasons. Firstly, chronics are very popular in local area. The chronics greatly influence the health of Lizu elderly people and reduce their physiology functions. Secondly, education degree affects the health of Lizu elderly people. Most of Lizu elderly people are illiteracies (76.5%), and they lack the consciousness of self-health care. Thirdly, most of Lizu people have a big family. Children couldnt spend enough time to attend their parents. Local economic income is relatively low and lead to the low level quality of life. 3.13 main factors that may affect the quality of life were analyzed by analysis of variance and T-test.

考虑是该地区黎族老年人患有慢性病人数较多，慢性病患病率高，长期受疾病的侵扰，生理机能衰退，也可能是黎族老年人文盲率较高(76.5％)，文化程度较低，自我保健意识较弱，也可能是黎族同胞传统的大家庭结构，造成家庭人口数多，家庭经济负担重，子女照料老年人时间较少，导致黎族老年人生命质量不高。3、用t检验和F检验对可能影响黎族老年人生命质量的13个因素进行分析，这些因素包括性别、年龄、文化程度、婚姻状况、生活来源、经济状况、医疗费用负担形式、是否患有慢性病、家庭结构、吸烟、饮酒、居住环境、生活满意度。
