问题定量限常按一定信噪比（S/N)时相应的浓度或进样量来确定，该信噪比一般为

选项 A:2:1 B:3:1 C:5:1 D:7:1 E:10:1

答案 E

解析常用信噪比法确定定量限，一般以信噪比为10:1时相应的浓度或注入仪器的量确定定量限。

错误啦！

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
