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.

4塔克拉玛干沙漠新月形沙丘及沙丘链主要是在窄单峰风环境中发育而成，RDP/DP值一般都在0.8以上；复合型纵向沙垄主要是在双峰风况条件下发育而成的，RDP/DP值在0.55左右：穹状沙丘形成于均衡的多风向地区；而金字塔沙丘一般都形成于下伏地面微有起伏或邻近山岭的地带。

As a new branch of mathematics and with a great ability to describe and study natural phenomenon, fractal geometry has attracted a good deal of attention and has been applied in more and more fields.

分形几何作为一个新兴的数学分支，为描述复杂事情提供了一套崭新的工具，在越来越多的领域得到应用。

With a gradual contraction longitudinal straight inlet port applied on the Multi-Point Injection natural gas engine, the concentration of natural gas and the pressure field in the intake manifold after the injection of natural gas were investigated, then in the following intake process the volocity vector map and mass distribution of natural gas inside the cylinder were also numerically examined.

在此基础上，考察了渐缩形直进气道应用於多点电喷天然气发动时，天然气喷射后进气岐管内的天然气浓度场和压力场，以及随后天然气-空气混合气在气缸内的质理分布和速度分布。

Needle valve:This multi-turn valve derives its name from the needle-shaped closing element.
