能见度

Use of lower wavelengths, such as those available with the mercury lamp lines isolated by means of filters of maximum transmittance at approximately 578, 546, 436, 405, and 365 nm in a photoelectric polarimeter, has been found to provide advantages in sensitivity with a consequent reduction in the concentration of the test compound.

使用较低的波长，例如那些利用光电旋光计过滤掉汞灯线在578、546、436、405、365nm的最大能见度所产生的，已经被发现有利于增加检验敏感性，并最终导致供试品浓度的降低。

Based on the relation between the attenuation ratio and the transmittance of the laser, the variation of the attenuation of 10.6μm laser traveling in advection fog or radiation fog with the visibility and the FOV of the laser receiver is given.

最后，以工作波长为10.6μm的激光为例，利用衰减率与透过率之间的关系，给出了平流雾及辐射雾中激光雾衰减随能见度、接收器视场角等的变化关系。

The result is excellent rearward visibility for the driver, with a high level of privacy for the rear-seat passengers.

其结果是优秀的司机后方的能见度，以隐私为后排乘客的高水平。

In addition, retractable rear headrests and rear three quarter lights increase rearward visibility.

此外，伸缩后头枕和后三个季度的灯向后增加能见度。
