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.

结果表明：中尺度飑线所伴随的强风暴是产生强沙尘暴的主要原因；500 hPa阶梯短波槽是中尺度飑线产生的大尺度触发系统，河西走廊中西部700 hp变形场、中尺度低压为强沙尘暴形成和维持提供了必要的动力条件；地面冷锋前上升运动与高空急流入口区次级环流的上升气流的叠加，为深对流发展提供了深厚的垂直环流发展条件，是促使飑线发生和沙尘卷起的基本动力；地面热低压的加强和午后气温的日变化加大了冷锋前后的温度和气压梯度，为大风、强沙尘暴爆发提供了必要的热力不稳定条件；强沙尘暴出现在垂直螺旋度为－200平方公尺/s^2中心的下游，垂直螺旋度对飑线的发展和沙尘暴的落区具有较好的指示意义；中尺度飑线发生在不稳定层结内，较强的不稳定层结为强沙尘暴形成、发展提供了位能转化为动能的基本条件。

Also, the eigen frequency of trough structure resonant cavity and anisotropic media loaded resonant cavity was calculated.

该方法通过归一化电压和归一化电流直接求解出归一化的导纳矩阵，进而求解出微波网络的S参数矩阵。

I get the glimmerings of it around November, as the days get shorter, and then it worsens, and hits a peak or trough, should I say!

我得到一丝的，它周围的11月，随着时间的缩短，然后它恶化下去，并创高峰（或谷底的时候，我应该说！

The thesis tends to investigate the establishment of the insurance cycle score and business cycle of the premium of new business. We utilize six kinds of different insurance of new business to be our investigate object, that including ordinary life insurance, group life insurance, individual health insurance, group health insurance, personal accident insurance and group accident insurance. Besides observing fluctuate of the firsthand information, we used the maximum likelihood estimation to estimate the unknown parameter of Markov switching models. Try to cognizance the peak and the trough of business cycle.

本研究在探讨保险新契约之保费的景气循环状况与景气分数的制定，其中我们利用六种不同的保险新契约保费当研究对象，包括个人人寿保险保费、团体人寿保险保费、个人健康保险保费、团体健康保险保费、个人伤害保险保费和团体伤害保险保费，除了观察原始资料的波动外，亦采用最大概似估计法来估计马可夫转换模型的未知参数，尝试著去认定景气循环的高峰与谷底。

After reaching a low near 30 1/2 in early February, the trough formed over the next 2 months, and there wasn't a rally until early April. This long-drawn-out low suggested tepid demand.

在2月份股价达到新低30美元后，波谷低用了2个月的时间来形成，在4月份前都没有交易量的反弹，这反映了较低的需求量

However, the latter more complicated, contrasted between radar data and routine observatory data. It can be seen that the classification of the storm rainfall echo according to 850hPa effective system is more ideal, the storm rainfall echo is classified into storm rainfall of trough and storm rainfall of shear line, while storm rainfall of shear line includes storm rainfall of warm shear line and storm rainfall of cold shear line, and their radar echo features are investigated. It is shown that different storm rainfall style is distinct clearly on the echo structure and feature.

而伴有低空急流暴雨的回波特征较复杂，通过对雷达资料及常规观测资料的对比分析，发现利用850hPa的影响系统对暴雨回波分类比较理想，将暴雨过程分成低槽暴雨和切变线暴雨回波两类，切变线暴雨又可以分为冷式切变线暴雨和暖式切变线暴雨，分别分析、研究了不同类型暴雨的多普勒天气雷达回波特征，结果表明不同类型暴雨的回波结构和特征具有明显的区别。
