正交展开 meaning in English
orthogonal expansion
Examples
- The result of the two experiments implied that the correcting scheme of combined eof reached the level of operation . it is valuable greatly for climate prediction
订正试验、预测试验的结果说明联合自然正交展开订正方案已经达到实际业务应用的水平,这对于气候的跨年度预测,尤其是对enso预测有十分重要的应用价值。 - Because the system error is ineluctable for mode , it is necessary to correct the simulation fielde effectively . in this paper , based on the idea of combined eof correction , the interannual simulation of sea surface wind stress anomalies of the tropical pacific ocean by lap two - level atmosphereic model have been corrected , result of corrected erperiment shows that the corrected field is more similar to the observation field , especially on the distribution of the space . three prediction experiments also shew that correcting scheme of combined eof can improve the interannual prediction veracity of model
在本文中,基于“联合自然正交展开误差订正”的思想,将中科院大气物理研究所两层大气环流模式输出的热带太平洋海表风应力异常的跨年度模拟场进行订正,订正试验的分析结果表明,订正后的热带太平洋海表风应力距平场与相应观测场年际变率分量的相似程度远远好于模式模拟的结果,尤其是在空间分布方面的改善非常显著;三组跨年度订正检验结果也表明,订正后的跨年度预测结果明显好于模式的预测结果。 - We have the following results . part i the computations of the bergman kernel functions the bergman kernel function plays an important role in several complex variables . s . bergman introduced the concept of bergman kernel function in 1921 when he studied the orthogonal expansion on d in c and he generalized it to the case in several complex variables in 1933
Bergman核函数的显式表达bergman核函数在(单、多)复变函数理论的发展过程中起着十分重要的作用, bergman在1921年研究复平面中区域d上的正交展开,其研究结果导出了一个核函数k _ d ( z , ) , ( z , t ) d d 。 - 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 unified approach can be applied to it to acquire the ensemble random evolutionary response . since the normal probability density function ( pdf ) may lead to instability of some sample systems when the random parameters taking sufficiently small negative values , an arch - like pdf and a more adaptable - pdf , together with the matching chebyshev polynomial approximation and gegenbauer polynomial approximation , are suggested . numerical examples show that the suggested methods are effective
相比较而言,随机模拟法的结果无疑是最可靠的,但是它的计算量嫌大;随机摄动法的计算量远小于随机模拟法,但是它要求随机摄动量必须是一个小量;正交展开法的计算精度好于随机摄动法,其得到结果与随机模拟法得到的结果几乎吻合,其计算量略多于随机摄动法,但与随机模拟法相比要少的多,不过计算前的准备工作较费时。
