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。

Culm sheaths deciduous, leathery to thickly papery, usually rigid, white powdery, apex truncate or concave, sometimes with subcircular projection at base of one margin; auricles usually inconspicuous; oral setae usually developed; ligule short, truncate, margin serrulate or fimbriate; blade usually reflexed, adaxially densely hispid, apex usually involute.

竿箨脱落，似皮革的到厚纸质，通常硬，白色粉状，先端截形或者凹，叶耳通常不明显；口头的刚毛通常发育；叶舌短，削去，边缘有细锯齿或流苏状；叶片通常反折，正面密被糙硬毛，先端通常内卷。

The subendocardial and sub-epicardial tissues were separated from the mid-layer region with opthalmic scissors. Single cells in each region were obtained by gentle shaking and dispersing in a chamber filled with normal Tyrode's solution. The whole-cell patch clamp technique was used to record the current while change the composition of the perfusate.

The number of elementsin this flow-resistor network can be determined by the tracheid length,radial diameter andtangential diameter of tracheid and the dimension of specimen.

根据Zimmermann有关实验结果以及气体在针叶材中流动的路径，气体在试件内的流动通道分成为不同的区域，气体将不会在这些区域之间流动，即各区域间的流阻不相连接；且这样的区域在三个纹理方向的管胞数目相同都等于管胞在试件纵向排列的数目。
