There must be a threshold of thermal noise .

必有一个热噪声的门限值。

The CDS readout circuit can inhibit thermal noise as well as flicker noise of the microbolometer effectively, and the thermal noise dominates the output noise voltage.

CDS读出电路能有效地抑制微测热辐射计的热噪声和闪烁噪声，并且输出噪声电压中热噪声占主要部分。

The square voltage was used to describe thermal noise voltage in determination.

热噪声电压通常采用均方值定量描述.
