| 1. | Their oscillation periods , anomaly years and years of catastrophe etc are also analyzed in this paper
并分析了它们的周期、异常年份和突变年份等。 |
| 2. | The time series of temperature are expected to be the longest possible so as to examine various modes of oscillation periods
人们希望温度的时间系列尽可能地长，以便能研究各种波的振荡周期。 |
| 3. | There are obvious interannual variations in spring precipitation in shandong province , and the oscillation period is about 4 . 8 - 6 year
应用自然正交函数展开( eof )方法，分析了山东省38年春季月、季降水量。 |
| 4. | 3 ) , the joint uprising branch is located around the equation , basically on the summer hemispheric side , and it is strong in january and july and weak in april and october , which has a two - year oscillation period
3 ，北、南半球hadley环流圈及其共同上升支位于赤道附近，但偏于夏半球一侧，其强度1 、 7月强， 4 、 10月弱，做年双周振荡。 |
| 5. | The strengths of hemispheric hadley circulations are strong in winter and weak in summer , which have one - year oscillation period . 2 , it is basically equivalent of the strengths of the both hemispheric hadley circulations in april and october
2 ，半球hadley环流圈强度冬强夏弱，做年单周振荡，过渡季节( 4月和10月)两半球hadley环流圈强度相当。 |
| 6. | The calculation of dynamic response under the loading of incident pulses with different rising - time shows that the oscillation of stress wave reflects the macro - heterogeneity of laminated materials , and that the oscillation becomes more distinct as the rising - time becomes steeper . for the periodical laminate , the oscillation period of stress wave depends on the width of each cell and the width of the whole representative cell
针对两种不同上升沿入射波加载时的计算表明，应力波的振荡现象反映了材料的分层非均匀特性，上升沿越陡，振荡越明显；对于周期性分层材料，应力波的振荡周期与各层的厚度以及周期性代表单元的总厚度是相关的。 |
| 7. | The anti - rolling tanks have three types including passive anti - rolling , controlled passively anti - rolling tank and active anti - rolling tank . the controlled passively anti - rolling tank has high performance , and it can adjust the water oscillation period through the valves in the upper of side tank in order to adapt the roll period . thus the controlled passively anti - rolling has favorable effect in the any states
其中，可控被动式减摇水舱是一种高效能的减摇水舱，它可以通过自动控制系统调节边舱顶部的气阀开关来调节水舱内水流振荡周期，以适应经常变化的横摇周期，保证在任何海浪作用下水舱都具有良好的减摇效果。 |
