This research was conducted in degraded rangeland at the southwestern edge of the Mu Us sandland, Yanchi county, Ningxia, the soil seedbank features and its relation to vegetation was analyzed using similarity analysis and ordination method, the results show that seeds within soil distribute mainly in 0~5 cm soil layer, less seeds in 6~15 cm soil layer in exclosed and non-exclosed rangeland, for seeds in exclosed soil, species richness and diversity index H are higher, while D is lower, exclosure measure, generally speaking, can increase plant species and amount of vegetation and seeds in soil, some annual plants, mesophytes and halophytes appears in the soil or surface.

以毛乌素沙地西南缘宁夏盐池县的退化草场为研究对象，采用相似性分析和排序方法对封育和未封育草场土壤种子库的特征及其与地上植被间关系进行了研究，结果表明无论封育区还是未封育区，土壤种子库中的种子主要分布于0~5cm的土层，6~15cm土层的种子数很少；封育区土壤种子库的物种丰富度大于未封育区，物种多样性则表现为H 值较大，而D值较小，总体上看封育措施可以提高地上植被和土壤中种子的种类和数量，一些一年生植物、中生植物和盐生植物开始出现在地面或土壤种子库中。

通常的虚边界积分公式是利用单层位势的延拓来建立虚边界元积分方程，但对带时间变量的单层位势，要涉及到指数积分函数的计算。

Methods: From May 1985 to December 2002, 2240esophageal and stomach cardia cancer patients treated by intrathoracic esophagogastric "layer-to-layer"anastomosis with esophageal mucosa extended varied in plane were retrospectively analyzed.

回顾性总结1985年5月～2002年12月共进行胸腔内食管黏膜延长不同平面与胃、食管分层吻合术2240例，统计手术后和出院后随访资料发生吻合口瘘和吻合口狭窄的情况。

To evaluate the clinical value of intrathoracic esophagogastric "layer-to-layer" anas tomosis with esophageal mucosa extended varied in plane and to study the effective methods to prevent anastomotic leaking or stricture postoperatively.

目的 评价胸内食管黏膜延长不同平面与胃、食管分层吻合术，探讨预防食管吻合口瘘和吻合口狭窄发生的吻合方法。

Intrathoracic esophagogastric "layer-to-layer" anastomosis with esophageal mucosal extended varied in plane is an ef fective method to prevent anastomotic leaking and stricture postoperatively.

HF communication generally depends on the reflection of signals from the higher F layer and such signals must travel through the D layer at least twice.

HF 通信一般取决于信号的反射从更高的F 层数并且这样信号必须游遍D 层数至少两次。

Pattern A and B are for the threads. C is created using the noise filter and vertical motion blur. D is another layer of just noise and E is the scaled version of D. F is a layer with random black and white dots. A and B is passed through a distort-glass filter just to give it that random weaving effect.

图案A和B是细线。C的创建是由杂点滤镜和垂直运动滤镜模糊制作的。D是另一层就是杂点，E是对D的放大结果。F是一层随机的黑白点构成。A和B再通过扭曲里的玻璃滤镜得到一个随机编织效果。

For a heterogeneous elastic solid consisting of two homogeneous layers, three homogeneous layers whose shear wave velocities increasing with depth, or three homogeneous layers whose interlayer has high velocity, if there are multi-mode dispersion curves, the phase velocity V〓 of the first mode will close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, and V〓 of the first mode will close up to the Rayleigh wave velocity of the top layer when f→∞.

由多导波模式的相速度频散曲线还可知，对于二层固体介质、结构层的横波速度随深度而递增的三层固体介质、含硬夹层的三层固体介质而言，若频率f→OHz，其基阶模式的瑞利波相速度V〓→V〓（V〓为最底层介质的瑞利波速度）；若f→∞，其基阶模式的V〓→V〓（V〓为最上层介质的瑞利波速度）；因此，随着频率f逐渐升高，野外实测的瑞利波相速度V〓曲线应该主要为基阶导波模式。
