Photo of the Day January 24, 2008 Sand Dunes, The Dalles, Oregon, 2001 Photograph by Jim Richardson In a curious juncture, a wrinkled span of desert dunes pours into the Columbia River Gorge in The Dalles, Oregon.

位于俄勒冈州，达拉斯有一个古怪的结合点那就是具有皱纹横越沙漠，沙丘涌入哥伦比亚河的峡谷。

0M/s.(4) The barchans dunes developed in narrow un-modal wind regime, the value of RDP/DP is greater than 0.8; the compound longitudinal dunes mainly developed in modal wind regime whose value of RDP/DP is about 0.55; the dome dunes developed in those areas that have directional winds and their force is balanced; and the star dunes mainly distributed in areas which have wavy terrain or approach mountains.

Reddish and orange-coloured dunes, dunes behind dunes beyond dunes, loneliness and burning silence, and two men on two dromedaries in that swinging gait which makes you sleepy, so that you forget the day, the sun, the hot wind and the long way.

Reddish and orange-coloured dunes, dunes behind dunes beyond dunes

泛红的和橙色的沙丘，沙丘续着沙丘，沙丘远处还是沙丘。

The changing trend was induced by area fluctuation of semi-mobile and semi-fixed dunes because 2.6% area of semi-mobile dunes and 12.3% area of semi-fixed dunes were unchangeable during 1987 to 1995. And, most changeable area of the semi-mobile and the semi-fixed dunes transferred to other sand-dune types and cropland.

沙漠化程度的变换主要是由半流动和半固定沙丘的变化所导致，其中在1987-1995年期间，半流动和半固定沙丘分别只有2.6%和12.3%保持不变，其余部分主要转移成其他沙丘类型和农田。

The sand dunes analyses data have shown they mainly consist of well sorted, symmetry skewness and find sands, and the kurtosis peak is narrow or very narrow. There are abundant impacts of mechanic process on the surface of quartz grains. The traces of eolian process often superpose on the traces stamped by river and beach processes. The dish--shaped concavities and mechanic pits are the most common surface textures, but the barchan concavities and curved grain edges are indicated the marks by eolian environment. The heavy minerals assemblages of coastal dunes are dominated by relatively high specific gravity which have stable chemical properity suggesting the mordern high dynamic environments of coast area. The depositional structures of coastal dunes are typified by corss--bed sets composed of steep foreset laminates and gentle windward dipping sets. It also contains some shell fragments and strong worn foraminiferal tests that are impossibly found in inland desert. On the other hand, the sandy deposits of the continental shelf of East China Sea are with wide range of grains, and the depositional pattens are quite complicated.

海岸沙丘是晚全新世以来相对稳定的海平面背景下的海岸带风成堆积，其沉积特征是以细沙为主，分选好，搬运方式以跃移占绝对优势，偏度上近对称，峰态窄到很窄；石英颗粒表面机械作用形态丰富，风成作用形态叠加于河流和海滩过程形态之上，碟形坑和撞击麻点是最为常见的表面形态，而新月形坑和曲脊是其指示性的特征标志；沙丘沙重矿物以化学性质稳定、比重较大的种类为主，反映了海岸带目前的高能动力环境；海岸沙丘沙的沉积构造以高角度前积层和低角度顶积层组成的交错层理为典型特征，同时还含有少量内陆沙漠所没有的少量贝壳碎屑和强烈磨损的有孔虫壳体。

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
