spectrum value meaning in Chinese
谱值
Examples
- Results show that all the parts of the artillery produce vibration acceleration in the traveling course . the power spectrum is mainly in the low frequency segment . worse road surface and higher speed will cause higher power spectrum value of the acceleration response
结果表明火炮牵引行驶过程中各部件均产生振动加速度，其功率谱主要分布在在低频段，路况差、速度高则加速度响应的功率谱值高。 - Roughly acquire optical depth of clear sky and clouds from radiation station data and routine meteorological data of land surface , and the study the relationship between clouds " physical character and radiation . obtain the relationship between surface and near - ground atmosphere , and then according to this estimate surface albedo and surface net . by analyzing the relationship between satellite visible spectra , infrared spectra , and water vapor spectra values and radiation , by means of radiation transfer theory , analyze and deducethe relationship between clouds and radiation , and establish relationships between satellite value and global radiation and net
通过卫星云图的计数值来判断云对辐射的作用，以此建立起它们之间的关系；利用地面观测资料和常规资料来粗略求取晴空大气和云光学厚度，进而研究云的物理属性与辐射关系；简单的获取地表与近地面大气之间的辐射关系，以此估算地表的反照率，和地表的净辐射；分析了卫星可见光、红外及水汽云图计数值和地面辐射之间关系，利用辐射传输公式来推倒和分析云对辐射的关系，试图建立起卫星测值与地表总辐射和净辐射之间的关系，并将晴空和有云的个例分开，分别建立并选出最佳模式，以此来估算地表的净辐射和总辐射。 - For the analog low - gain displacement - type records , two horizontal - component records of a m7 . 1 aftershock of tangshan earthquake , july 28 , 1976 , in tai ' an seismic station are used as the example to show the procedures of digitizing , arc - shape correction , baseline correction , equal - interval interpolation and instrument response correction . the reliability of the analog low - gain displacement - type records for long period study is also discussed . in order the database to have a better magnitude - distance distribution , a method to estimate the long period response spectrum values from earthquake magnitude definition is developed
对于模拟式低放大倍数位移记录，以泰安地震台的513型中强地震仪所记录的1976年7月28日唐山地震的7 . 1级余震两个水平分向的记录图为例，详细说明了对记录图数字化、弧型校正、基线校正、等距插值、仪器响应校正等步骤，计算了周期t 10s的反应谱，分析了它们的可靠性。 - 754 horizontal - component digital broad - band records in western north america are processed . the acceleration response spectra are calculated and used as part of the database . the response spectrum values are estimated by the earthquake magnitude definition and are used as another part of the database
将美国西部地区作为参考地区，对美国南加州地区的数字宽频带记录进行了搜集与处理后作为观测资料，共754条水平向记录，与利用震级定义所估计的反应谱值一起，用统计回归的方法建立美国西部长周期加速度反应谱衰减关系。 - Firstly , fourier descriptor used to describe the object ' s shape is introduced to the extraction of feature of apple ' s shape . the boundary of apple is an obturated curve , distance between boundary point and centroid r ( k ) " is used as a function to express the 2 - d boundary in spatial domain . the fourier transform coefficients of the discrete sequences f ( h ) are spectrum values in frequency domain , and they compose feature parameters of shape
首次将图像分析理论中对形状的傅立叶描述方法引入到对苹果形状的特征提取中，果实边界是一条封闭曲线，用边界点到形心之间的距离长度r ( l )作为空域中对二维曲线的表达函数，离散的函数值序列r ( k ) ~ l的离散傅立叶变换系数f ( h )就是频域中得到的频谱值，可作为形状的特征参数。
