It has an electric field with the same order as that of the SKAW on the Alfvén velocity branch, but its magnetic field is weaker than that of the latter by a factor of (β/2)1/2=Cs/νA, where Cs and νA are, respectively, the ion-acoustic velocity and the alfvén velocity.

它具有一个与阿尔文分支上SKAW同一量级的扰动电场，但扰动磁场比后者低β1/2倍。

The field experiments on the near surface airflow, sand transport rate, grain size of the dune sands and the morphology of the dunes show that though shear velocity decreased at the toe of the transverse dune, the threshold shear velocity decreased simultaneously. 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.

对简单横向沙丘表面的气流、输沙率、物质结构，以及形态学特征的观测表明，在横向沙丘迎风坡坡脚尽管剪切速度有所下降，但起动剪切速度同时减小，起动剪切速度减小与不饱和风沙流是沙物质在迎风坡坡脚不能产生沉积的主要原因。

叠加速度谱不仅可以提供速度信息。而且能量团的聚集、发散特征也可以提供油气、构造方面的信息，其接合地震剖面的解释可以提供更多的地质信息。

In this paper, those teleseismic records with clear P waveforms are chosen to carry out receiver function analysis and modeling. A simple crustal structure model beneath the station is obtained, in which the Moho depth is 28 km. On the top of the upper crust is a 2 kmthick low velocity layer with a shear wave velocity of only 23 km/s. The shear wave velocity increases gradually with depth to 38 km/s in the lower crust.

本文对具有清晰P波波形的远震记录进行了接收函数处理和计算模拟，得到台站下简单的地壳结构模型，其莫霍面深度为28 km，上地壳顶部有一层2 km厚的低速层，横波速度只有23 km/s，向下逐渐过渡到横波速度为38 km/s的下地壳。

Methods: 60 patients with good temporal window and 25 patients with poor temporal window (bilateral: 8 cases, unilateral: 17 cases) were examined by TCD. Systolic velocity, mean velocity, diastolic velocity, and pulsatility index in MCA were evaluated. 6 cases out of 60 patients with good temporal window were measured in transoptical and transtemporal detecting angle by MRI.

对颞、眶窗检测信号良好的60例患者分别在2个部位测定MCA的峰值流速、平均流速、舒张末期流速和脉动指数，对其中6例行MRI检查者测量了经颞及经眶的检测角度；另对25例颞窗双侧或一侧缺如者行眶窗检测MCA。

The other one retrieves vertical velocity from the reflectivity using statistical algorithm and assimilates the vertical velocity taking Richardson's equation as observational operator. It is found that the vertical velo city derived by the former is usually too weak while the later gets the distinct three dimensional convective structure of meso-scale system with strong vertical velocity.

其一是采用Richardson方程通过水平风场、温度和气压来对垂直速度进行诊断，其二是利用统计方法由观测的反射率因子反演出垂直速度后，再采用Richardson方程作为观测算子对反演的垂直速度进行同化。
