Regarding natural sand of the spot as model sand , using series model , and under the interaction of irregular wave and tidal current , a systematic test on scouring around pile of land - island approach bridge of jiangsu lng receiving station is carried out 摘要以现场天然沙为试验床质,利用系列模型,采用不规则波与潮流相结合的方式,对江苏lng接卸站陆连岛桥桩基周围的冲刷情况,进行了系统试验。
In the detached leaf test , tr within 12 minutes after leaf detached exhibited a irregular wave . average tr ( atr ) had a a slight increase at prophase then declined . trend of liner atr presented well controling tr property 在离体叶片蒸腾变化试验中,离体叶片12分钟内蒸腾失水速率表现为无规则律动;平均蒸腾速率初期“ tr )有一个小的上升趋势,然后下降: r的线性分布较好地体现出离体叶片对蒸腾速率的控制能力。
The innovation of this paper includes : 1 ) on the measure principle , author broke through the stipulation of the current regulation rule , analyzed the problem of original measure method , and suggested that we should take the virtual value principle to measure the irregular wave 本文的特色之处在于: 1 )在测量原理的问题上,敢于突破现有条规的约束,分析了原有测量方法的问题,提出应该采用有效值原理的方法对不规则波形进行测量。
This paper presents that the directional spectra and the reflection coefficients of the oblique and the multidirectional irregular waves on the co - exist wave field of incident wave and reflected wave have been studied . a modified two - points method is proposed that can be used to calculate the frequent spectrum and reflection coefficient of the oblique waves . for the multidirectional irregular waves , the directional spectra and reflection coefficients are obtained by the modified bayesian directional method and the modified maximum likelihood method 本文研究了入、反射波共存场中斜向不规则波和多向不规则波波浪场的方向谱和反射系数,对于斜向不规则波频率谱及反射系数的计算提出了一种改进两点法( mtpm ) ,对于多向不规则波方向谱和反射系数的分析,应用了改进的贝叶斯方法( mbdm )和改进的最大似然法( mmlm ) 。
