The effects of the cold fronts upon the night f0F2 are found out by using the records from the cold fronts years book and ionosonds measurements of Wulumuqi and Changchun. From the statistical analyses of large number samples from 1968 to 1975 and the superposed epoch analyses with the day of the minimum temperature during the processes as the key day, it is shown that the f0F2 tends to decrease when a could front passes across. The maximum decrease is at the key day in the superposed epoch analyses. The pereentage values of the decreases are 4%-8%. It is larger in solar low-activity years, and the variation is also larger in Wulumuqi than in Changchun, x2-and U-test have been used to demonstrate the significance of the respose. The effects are probably caused by the gravity waves from the Jet-stream?generated Kelvin-Helm-holtz Instability within the cold front area. Gravity waves may propagate upward and produce the up-down oscillation in ionosphere. The integrated decrease of the f0F2 and the difference between the high and low activity years can be interpreted by his mechanism as well as the station-to-station difference.

本文利用1968—1975年“寒潮年鉴”和乌鲁木齐、长春两站电离层f_0F_2资料,讨论了寒潮过境对夜电离层的影响.对个别样本的统计分析,特别是以地面气温最低日为标准日的叠加周期分析,均说明寒潮过境时夜间f_0F_2有下降趋势,平均说,在标准日下降最大,而后恢复.下降的百分值在太阳活动低年比高年大,乌鲁木齐站则比长春站大.这一下降的可能原因,是寒潮中激流带底部风切不稳定性产生的重力波向上传至电离层高度,对电子浓度分布影响的积累效应.此初步设想能定性说明统计分析中的一些基本特性.

The results of statistic tests of random numbers uniformly distributed at the interval (0,1) generated by three generators of M340s computer are discussed. The magnitudes of the correlation coefficients of the three kinds of random numbers are also calculated using statistical method for large sample size . A new random number generator that can more conveniently be used in FORTRAN is presented.

对M340S计算机三个随机数发生器产生的(0,1)区间均匀分布的随机数进行了统计检验。结果表明:它们的均匀性、参数、正负速及升降连都在相同的显著水平α=0.05下通过价验;独立性相关系数检验则不同,有两种随机数在不同的显著水平α=0.05 和α=0.1下分别接受了不相关的假设,有一种在显著水平α=o.o5与α=0.1下均拒绝不相关的假设。通过大样本统计,给出了三种随机数的相关系数的数量级。最后为FORTRAN构造了一个使用更为方便的随机数发生器。

NOAA-7 satellite temperatures over the East Asia from February 13 to March 1. of 1984, collected by the satellite Meteorological Centre, retrieved with the statistical regression method and compared with the adjacent radiosondes, are verified statistically with large amount of samples. The characteristics of the errors' horizontal and vertical distributions and their day-night changes are analyzed and discussed. ?
