Two dominate variation trends are distinguished in the data plots of compressional-wave velocity versus Possion ratio, indicating the effects of mud content and calcite cement on the elastic properties of sandstone samples. In each change trend, with the rock texture transfering gradually from grain-supporting to matrix-supporting with increasing mud and calcite cement content, the propagation of elastic wave also changed from grain-to-grain contacts to rock matrix, which resulted in the measured data illustrating extremely different tendency. It helps utilize the physics properties of reservoir sandstone to extract rock texture and diagenesis properties in the research area.

样品在纵波速度－泊松比交汇图中表现出两种主要变化趋势，分别对应泥质与钙质胶结物的影响；在每个变化趋势中随泥质含量与钙质胶结物含量的增加，岩石结构从颗粒所构成的骨架支撑逐渐表现为基质支撑，弹性波能量的传播也从通过颗粒接触边界转变为通过岩石基质传播，这是使砂岩样品测试结果表现出两种截然不同变化趋势的主要原因，为利用岩石物理特性从地震资料中提取岩石结构、沉积与成岩特征的信息提供了依据。

Numerical analysis indicated that B2817 was a species of genus Vibrio and shared a high homology with V. gazogenes. However, there were obvious differences between them in phenotypic and chemotaxonomic characterization. The result from this study indicates that B2817 is probably a novel species of Vibrio.

经多相分类学鉴定，发现B2817是弧菌属中一个种，与弧菌属中的产气弧菌Vibrio gazogenes亲缘关系最近，但两者在形态、生理生化特征、分子遗传等方面存在很大差异，故认为B2817可能是弧菌属的一株未被认识的新种。

In particular, its business card printing and membership card making functional properties is publicity guide a packaging business card printing and membership card making, rather than selling ink merchandise, special-purpose business card printing and membership card making ink if you changed to another type of packaging printer carrier characteristics, this ink than other ink quality advanced.

特别是它的制卡和会员卡制作功能性质在于宣传引导一种包装制卡和会员卡制作新潮流，而并非畅销的油墨商品，专用制卡和会员卡制作油墨如果换上另一种包装承印载体特征，这种油墨也许比其它油墨质量高级。

Through the comprehensive research of the typical igneous seismic profiles in Qiongdongnan basin, the stocks, laccoliths, sills and dikes were identified from other seismic characters, and their identification characters were also summarized.

通过对典型地震剖面的研究，识别出了岩株、岩盖、岩床和岩墙4种产状的侵入岩岩体，阐明了它们的地震信息识别特征，同时分析了不同产状的侵入岩与油气的关系，论述了8种与侵入岩有关的油气圈闭类型。

Levins's and Shannon-Wiener niche breadth formula and Pianka's niche overlapping formulae are adopted to quantitatively study the niche breadths and overlapping feathers of major plant species in Malan forest standing in the Loess Plateau as well as analyze the niche patterns of these major plant species following their successions.

应用Levins、Shannon-Wiener生态位宽度公式和Pianka生态位重叠公式，定量研究了黄土高原马栏林区主要植物种的生态位宽度和生态位重叠特征，同时对主要种在演替系列上的生态位变化规律进行了分析。

The results showed that liquorices in five different habitats differentiated into at least two ecotypes, which was significantly correlated with their habitats, MG liquorice and JG liquorice grew in habitats with higher aridity falling into one type and their young seedlings had high drought-tolerating capability, but DG liquorice and SG liquorice and NG liquorice belonged to the other type and their seedlings had lower drought tolerance than the former seedlings; of all climatic factors in liquorice habitats, water was probably the dominating factor affecting the differentiation of liquorice ecotypes.

同时，对种植在相同生境下的2年生子代植株的地上部形态特征进行了观测。结果表明，5种生境的甘草至少已分化为2种生态型，且与它们的生境有显著的相关性，生长在生境干燥度较大的民勤甘草和酒泉甘草为一类，其幼苗的耐旱能力较强，而生长在干燥度相对小的大兴甘草、沙坡头甘草以及内蒙甘草归为另一类，幼苗的耐旱能力也低于前者，甘草生境中气候因素的水因子可能是影响其生态型分化的主导因子。
