噪声

• There can be all manner of noise associated with various malfunction .
  可能有各种与不正常的工作有关的噪声类型。
• On migrated sections migration noise can become the equivalent limitation .
  在偏移剖面上，偏移噪声成为等效的界限。
• The noise temperature is in the most favourable case given by the temperature of the receiver .
  理想的噪声温度即是接收机的温度。
• There are also instruments known as noise meters which measure this level directly .
  还有一些可以直接测出声强级的仪器，叫做噪声计。
• The debris falling back to earth may generate additional direct and surface-wave noise .
  碎石落回地面可产生附加的直达波和面波噪声。
• We have paid a little attention to noise and to other sources of corruption of the data .
  我们附带讨论了噪声和其他引起资料畸变因素。
• An artificial circuit contains a little generator that is going to represent the noise .
  假想的电路中包括一个很小的表示噪声的发生器。
• As the range increases thermal noise tends to take over as the major source of inaccuracy .
  当射程增大时，热噪声将成为一个主要的误差源。
• The first term of the integrand represents the contribution to the error power due to noise .
  被积函数的第一项表示噪声对误差功率的影响。
• They are also quite useful in the analysis of noise problems, e.g. that of film grain noise .
  它们对分析噪声问题（例如底片颗粒噪声）也是很有用的。
