观测数据

Following that observation, we assume that weekly recognition performances for both algorithms and modalities are drawn independently and distributed according to a constant distribution, which we may assume to be Gaussian.

从观测数据我们可以假设这两种算法和两种形态的图像的在每一周的识别性能是相互独立的并且在局部是近似稳定分布的，因此我们可以认定为高斯分布。

However, the rationality of this assumption of homoscedasticity of random effects is doubtable. Therefore the verification for heteroscedasticity of random effects is absolutely necessarily and important for dealing with the regression problems in theory and practice.

因此观测数据的随机效应方差齐性检验是非常必要的，它是处理回归问题的重要步骤，在理论和应用上都有十分重要的意义。

This method provides an alterative way to obtain energy spectra of precipitating particles, and may also act as the complement of the lowertimeresolution limitations of satellite energetic particle observations. It is of high value in both academic and applied fields to establish models of space environment disturbance.

该方法开辟了获取沉降粒子能谱特征的一条新途径，可以弥补卫星能量粒子观测数据磁地方时分辨率的不足，对于建立空间环境扰动模式具有重要的学术意义和应用价值。

In this paper, a method to estimate the population in urban districts by using EO data has been studied and discussed.
