Especially the newly studied meridianal accelerating cleaning fan at mines is introduced, including the cleaning principles, structural characteristics, performance index and the cleaning results. 特别介绍了新研制的矿用子午加速除尘风机的除尘原理、结构特点、性能指标以及配套除尘器使用效果。
Meridianal Variation of Stable Isotopic Compositions in Precipitation of the Tibetan Plateau and Its Adjacent Regions 青藏高原及其毗邻地区降水中稳定同位素成分的经向变化
With the aid of statistical experiments, a feature of abrupt change of the meridianal circulation index and the pattern of spatial distribution of the surface pressure field has been found. It gives a possibility of short-range prediction of strong earthquakes, M ≈ 7 in Yunnan. 借助于统计试验,找到了经向环流指数的突变特征和相应的地面气压场的空间分布模型,从而给出了云南省大地震(M≈7)的一种短期预报的可能性。
The precipitation and regional averaged meridianal circulation indices, however, vary in the same phase. 降水与区域经向环流指数则有很好的同位相关系。
The rainstorm can be divided into zonal ( north, middle and south), oblique and meridianal types according to rain belt direction and its falling area. 按其雨带走向与落区可分为纬向(北、中、南)、斜向与经向类暴雨。

In order to transform conveniently the directional angle of a geodesic line into the geodetic azimuth, the solution of the meridianal convergence is expressed by geodesic coordinates of this point. 该解式直接采用该点的测地坐标来求解子午线收敛角,从而能方便地将测地坐标系中任一大地线的方向角转换为大地方位角。
The third gender A pair of the M8 meridianal Archidiskodon fossils have been collected from Chengcheng County of Shaanxi province. 在陕西省澄城县采集到一对保存相当完好的南方象第三上臼齿化石。
The two short-wave troughs moving eastwards intruded into the blocking high, which made the zonal trough created and became a meridianal one for two times, resulting in the strong cold air greatly moved into southern area. 两个短波槽东移侵入阻塞高压,使得横槽两次建立和转为竖槽,导致强冷空气大举南侵。

They showed that the stable winter meridianal flow following the circulation trough in this area, the Alps mountain and the Mediterranean Sea play important effects in the processes of cyclone generation and development. 结果表明,该地区冬季较稳定的槽后北风气流、Alps山和地中海在气旋生成和发展过程中具有相当的重要性。
In this method, both the three components of the displacement of a point on the middle surface of a shell and the meridianal geometric shape are approached by using spline functions whose cardinal splines are cubic B spline. 在本法中,壳体中面一点位移的三个分量及子午线方向的几何形状均用以三次B样条为基样条的样条函数来逼近。
Meridianal image line and sagittal image line are observed in a simple experiment. 本实验用很简单的设备,清晰地观察到光线在水面折射所形成的子午象线和弧矢象线。
The key of cyclone generation is the cooperation of the Alps and the meridianal flow which perpendicular to the Alps. 与Alps山正交的经向气流和Alps山的共同作用是地中海气旋初生的关键;
