查询词典 cold wave

The rules of the cold-test characteristics changing with helix pitch are also studied and it turns out that, with increasing helix pitch, the phase velocity increases linearly, the interaction impedance changes nonlinearly and the attenuation constant decreases nonlinearly. At the same time, with the limitation of the synchronism between the electron beam and the electromagnetic wave, the change of pitch is small and therefore an approximate linear relation can be introduced.

研究表明：相速几乎随螺距增大而线性变大，互作用阻抗与螺距是非线性的关系，衰减常数随螺距增大而非线性地减小；由于在维持电子注与电磁波速度同步的限制下，螺距变化的幅度不可能很大，因此可近似按线性关系来处理互作用阻抗及衰减常数与螺距之间的关系。

Based on the analyses of the observation data and numerical model of ocean circulation, the variations of the Kuroshio in Luzon strait (included Bashi strait and Balintang strait) have been studied by using the theories of potential vorticity conservation and oceanic Rossby wave; It was first discovered that the climatologic mean state of the Kuroshio exhibits a westward bending through the Luzon strait. The location of the Kuroshio bending is limited to the east of 119E and frequently flanked by a cold eddy to southwest of the Kuroshio; This bending of the Kuroshio favors the formation of the anticycle eddy in the east of the Luzon strait.

依据对海洋观测资料的分析，运用位涡守恒，海洋Rossby波动理论和数值模式，研究了黑潮在吕宋海峡（包括巴士海峡和巴林塘海峡）的形变特征；首次确定了在吕宋海峡黑潮的形变的平均状态是黑潮向南海的弯曲，该弯曲西端位置一般不超过119E，该弯曲的西南侧常常出现冷涡；该弯曲有利于吕宋海峡东侧形成一个反气旋涡旋。

The results indicate that the electron loss timescales due to artificial injection of ELF/VLF waves in the inner and the outer radiation belts depend largely on the value of the cold-plasma parameter α*(∝ B 2/ N 0, where B is the ambient magnetic field and N 0 the electron number density), the properties of wave frequency spectrum, the wave power and the electron energy in resonance with the waves.

The result showed that the strong storm followed by mesoscale squall line was primary cause of strong sandstorm producing, steps and ladders short wave trough of 500 hPa was great criterion triggering system for the mesoscale squall line producing, the essential dynamic condition was provided by distortion field and the mesoscale low pressure of 700 hPa for the strong sandstorm forming and maintaining in mid-west of Hexi Corridor, the deep vertical circulation development condition was basic power that urged squall line to occur and sand dust to curl up, which was provided for the deep convection development by superimposition of lifting movement before ground cold front and ascendant current of secondary circulation in upper air jet entrance region, temperature and the barometric gradient around the cold front was enlarged by enhancement of ground thermal low and temperature diurnalvariation of afternoon, by which essential thermal energy unstable condition was provided for the gale and strong sandstorm eruption, the strong sandstorm appeared in downstream of -200 m^2s^(-2) center of vertical helicity, the vertical helicity had good instruction significance for development of squall line and landing region of sandstorm, the mesoscale squall line occurred in unstable stratification, basic condition of potential energy transforming as kinetic energy was provided by strong unstable stratification for the strong sandstorm forming and developing.
