主要周期 meaning in Chinese
predominant period
Examples
- Adoption of a system essentially based on two main cycles , undergraduate and graduate
采用实质上是基于两个主要周期的系统,大学生和研究生。 - Rule 3 - - bull or bear campaigns seldom run more than 3 to 3 1 / 2 years up or down without a move of 3 to 6 months or one year in the opposite direction , except at the end of major cycles , like 1869 and 1929
规则3牛市或熊市在没有经过3至6个月或1年的反向运行时很少能超过3年至3年半2上涨或下跌，在结束主要周期时除外，例如1869年至1929年。 - With the rotational complex empirical orthogonal function rceof , we analyzed the spatio - temporal evolvement of the latest fifty years ssta of pacific ocean . came to a result that there are two strong signal center : one at middle and east pacific ocean near equator , the other at 40n . it will take several months to half a year for the signal to reach west pacific ocean from east coast of pacific ocean near equator correspond to enso
运用转动复自然正交展开rceof分析近50年太平洋海温场的时空结构，得出在赤道中东太平洋和40n附近有两个海温异常强信号中心赤道东海岸太平洋海温异常信号对应enso信号在几个月到半年左右传播到赤道西太平洋海温主要周期大部分落在310d的范围内，还存在年和准两年变化。 - Then the periodic properties of geocenter motion in the x , y , z components are summarized . considering the statistical precision of the gps observations , the geometrical distribution of gps stations and their physical stablility , a new method to determine the parameters of geocenter motion is studied and analyzed . in order to have a better understanding of its effect on the height datum origin , the rule of geocenter motion in the horizontal and vertical components are also analyzed and some useful conclusions are drawn
提出了将谱分析与抗差估计相结合的抗差谱分析方法，并用该方法分析了地心运动时间序列的主要周期特性；为合理地确定地心运动参数，详细研究与分析了一种新的定权方法对求解地心运动参数的作用，该方法充分利用了gps观测量的统计精度、点位的几何分布以及物理稳定性；为了明确地心运动导致的高程基准的变化，分析了地心运动对地面点的水平分量和垂直分量的影响规律。
