The load transfer and settlement behavior from the simulation results are also analyzed: most of the column load concentrates on the enlarged column cap, and distributes quickly, there is more load attenuation at the variable section. The skin friction of enlarged column cap develops more adequately than underside column. The column settlement concentrates on enlarged column cap, and soil settlement concentrates on a little area below the variable section.
利用三维数值模拟分析了钉形搅拌桩复合地基的荷载传递和变形特性:钉形搅拌桩桩身荷载主要集中在扩大头部分,且衰减较快,变截面处桩身轴力有较大衰减,扩大头桩侧摩阻力较大,下部桩体侧摩阻力较小;桩身变形集中在扩大头,桩间土变形则集中在变截面以下较短范围内。

Classification and principle of rigid waterproofer;2. The circinal cavities were found in calcium alginate beads and the cylinder holes were observed in zinc alginate beads from the SEM,which indicated that the volume of fraction of zinc alginate polymer was relatively bigger and the zinc alginate polymer chain was more rigid than that of calcium alginate .
凝胶的SEM照片可见,海藻酸钙的冷冻干燥颗粒内为较大的圆孔,海藻酸锌凝胶内为较小的长孔,表明海藻酸锌高分子链在凝胶颗粒中的体积分率相对较大同时刚性较强;卵清蛋白从海藻酸凝胶颗粒中释放的试验结果表明,由于上述海藻酸锌凝胶的特性,导致海藻酸锌对卵清蛋白扩散阻滞作用相对较强;根据试验数据计算得卵清蛋白在海藻酸钙、海藻酸锌凝胶颗粒中的扩散系数分别为1。

By comparing and analyzing, it is concluded that for simple and slow slope terrain, the change of wind speed around hill can be truly calculated by some experimental formula such as MSFD calculations. While for cliffy slope and complex terrain experimental formula cant calculate the wind speed truly, it is well to analyze the question by numerical simulation.
通过对比分析可得,对于简单的、坡度较小的地形,山丘周围的风速变化可以较准确的由一些经验公式,例如MSFD理论模型计算得出;而对于坡度较大的以及较复杂的地形,经验公式无法较准确地对风速做出估算,只能借助于数值模拟来分析。

It showed that the niche breadth and niche overlapping indexes of the enclosed grassland in 2007 are much lower than in 2006 as a whole; The niche breadth of Artemisia ordosica is bigger than other species in the region in 2002. In 2003, the dominant species were Artemisia ordosica and Salsola ruthenica. Their niche breadth indexes were 0.544 and 0.460 respectively. The results of niche overlapping in 2006 and 2007 also showed that the species with big niche breadth didn't always have big niche overlapping, and the niche breadth and niche overlapping did not have a positive direct linear relation.
结果表明:2007年封育区植物种的生态位宽度及种间的生态位重叠指数总体上较2006年有所降低;2006年黑沙蒿生态位宽度最大,达0.768,是06年封育区的优势种;2007年封育区的优势种为刺沙蓬和黑沙蒿,其生态位宽度值分别为0.544、0.460;2006年和2007的生态位重叠结果均表明,生态位宽度大的物种不一定和其他物种有大的重叠指数,较高的生态位宽度和较高的生态位重叠之间并不存在直接的线性关系;2006年、2007年较高的Pianka生态位重叠指数都出现在生态位宽度较小的物种之间。

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。

At the same time, the biomass of species-rich community was more sensitive to the change of environmental conditions, while communities with fewer species had a little change in biomass.2 There were a total of 87 vascular plant belonging to 27 families and 68 genus in the six communities. Most species had a narrow distribution and a lower local abundance, while few species had a wider range and higher local abundance, and this distribution trends varied in different communities. The endemics were positive correlation to y diversity.
物种丰富的群落生物量对环境条件的变化敏感,较过去显著降低,而种类构成简单的群落则变化不大。2在6种植物群落中共出现27科68属87种高等维管植物,大多数物种具有狭窄的分布范围和较小的局域多度,而少数种具有较广的分布范围和较大的局域多度,并且这种分布趋势在不同的群落类型中又有所不同,γ多样性高的群落中特有种的数量增加;而γ多样性低的群落中稀有种数量相对较少。

The quality of purified 2-KGA from its fermentation products was up to industrial standard. In addition, several hexoses, such as D-glucose and D-sorbitol can be utilized to synthesize 2-KGA by this newly-mixed culture. The growth and anabolism of the B529-V6 were studied in 4M〓 and 300M〓 fermentor respectively. The results showed that its growth and anabolism were affected by carbon sources, ratio of D-glucose and L-sorbose, nitrogen sources, growth factors, inoculum quality and culture condition including the initial pH value, temperature and ventilation.
