Cell copy to disk sample ratio holding within 1 % 细胞复制的速率维持在1 %
Quick sampled ratio 快速采样率:
Specifies that statistics will be gathered using an inherited sampling ratio for all existing statistics including indexes 指定收集统计信息时,对现有所有包含索引的统计信息使用继承的抽样率。
If the sampling ratio creates too few rows being sampled , the database engine automatically corrects the sampling based on the number of existing rows in the table or view 如果抽样率导致要抽样的行过少,数据库引擎将自动根据表或视图中的现有行数改正抽样。
With rapid advancements of digital video , however , there is lots of digital video systems having different spatio - temporal sampling ratio , having different standards and different formats , having different display equipment , in order to carry out different formats conversion 随着数字视频技术迅速发展,产生了各种数字视频系统,具有不同的时空分辨率要求,导致了不同的格式的存贮,传输和显示数字视频的标准出现。
