Patterns in Nature: Sand A ridged sand dune sparkles under the Nevada sun.

一个山脊沙丘发光闪烁在内华达州太阳之下。

Among 10 sampling plots selected,only Sophora alopecuroides, a plant with strong drought resistance grown on the top of the dune,only two accompanying species,such as Salsola ruthenica and Leymus secalinus occurred.

选择的10块样地中，只有耐旱能力很强的苦豆子生长在含水量较少的沙丘项部，主要伴生种只有沙蓬和赖草，赖草、沙蒿、猫头刺和柠条6块样地均分布在水分条件相对较好的沙平地，主要伴生种有10种。

Ordosica biomass and density was dependant on that of soil moisture, and in particular, there existed a significant positive correlation between the biomass and the moisture, indicating that on semifixed dune, soil moisture played a decisive role in the spatial heterogeneity of plant population.

由于沙丘地形对降水量的再分配在土壤湿度分布中的作用，土壤湿度和油蒿种群空间异质性相互作用的结果为地形的缀块性→土壤湿度分布的缀块性→油蒿种群分布的缀块性→油蒿生物量和密度的缀块性。

The decreased threshold shear velocity and unsaturated sand flows at the stoss slope of the dunes resulted the erosion at the toe of the dune. Under the medium and low drifting-sand winds the sands being transported have divergence with that on the surface, the mean grain size of transported sands is lower than that on the surface and the sand transporting is a stochastic process.

起动剪切速度减小与不饱和风沙流是沙物质在横向沙丘迎风坡坡脚不能产生沉积的主要原因；再者，平均风速并不能完全反映野外实际状态下气流的性质，在低－中强度的风沙活动过程中，被输送的沙物质的粒度组成与下垫面物质有明显的差异。

The field experiments on the secondary flow developed on the lee side show that there are strong sand transport potential at the lee side of the dunes near the surface because of the decreasing of the sand grain size and the other factors. The transport directions are nearly vertical to the dune trends. Those factors and the sand slumping on slip face, and the sand transport processes on the stoss slope make the transverse dunes maintaining their morphology under the advance processes.

对沙丘背风坡发育的二次流的野外观测表明，近地面一定高度内沙丘背风坡气流仍有一定的强度，由于背风坡的沙丘沙粒径较小等因素，背风坡气流仍保持一定强度的输沙率，输沙方向与沙丘走向基本上垂直，这种作用与沙物质向背风坡崩落、迎风坡的输沙过程等共同作用，因而使横向沙丘在运动中保持其形态。

The dune of Lake Wabby, the whole island is out of sand!

这张照片是公开的。

The gentle sweep of the dune bisects the frame and the energy of the plant is reinforced by its stalks thrusting skyward.

这柔和的沙丘平分图像和能量的植物是加强由它的茎秆加强推向天空。

The gentle sweep of the dune bisects the frame and the energy of the plant is reinforced by its stalks thrusting skyward.

温和的横扫沙丘平分画面和植物的活力是其加强了它的茎干指向天空。

The gentle sweep of the dune bisects the frame and the energy of the plant is reinforced by its stalks thrusting skyward.

温和地扫描沙丘平分这画面和植物的能量是加强它的茎秆插向天空。

The gentle sweep of the dune bisects the frame and the energy of the plant is reinforced by its stalks thrusting skyward.

植物那插入天空的茎秆强化了它的能量。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
