本底噪声

This is the background noise amplifier.

这才是放大器的本底噪声。

Therefore, the ultra-short beam current pulse of 2ns is able to be perfectly reconstructed. Through data processing, singular points, part of high-frequency noise and background noise are eliminated.

通过后期的信号处理，剔除了采样数据中的奇异点、部分高频噪声和本底噪声，消除了由于触发和被测信号不同步的客观条件造成的波形晃动。

Objective To calculate the least acoustic response value of children aged 0-6 years in a quiet room, and to explore the positive standards of hearing screening at different ages in some nonstandard audiometric room.

目的计算0-6岁儿童在相对安静房间(本底噪声≤45dB A)测听的最小听觉反应值，探讨在非标准测听室进行儿童听力筛查不同年龄组的筛查阳性标准。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
