By establishing a model based on the law of infrared radiation transmission in atmosphere and the characteristics of infrared imaging system for the apparent contrast between the target and the background, and analyzing the model over two wavebands to formulate the distance measuring formula and the distance resolving power formula, a passive distance measurement method is proposed for aerial point target distance measurement.

提出了对空中点目标进行被动测距的方法。基于红外辐射在大气中的传输规律和红外成像系统的特性，建立了目标和背景的表观对比度模型。通过对两个波段上对比度模型的分析，推导出了测距公式和距离分辨率公式。理论分析表明，只要得到大气在两个波段上的消光系数，通过测量目标在两个波段、两个时刻上的目标表观对比度，即可计算得到目标距离和目标径向速度，而距离分辨率则取决于系统的对比度探测能力及相关参数。

但是，由红外辐射分布转化过来的可见红外图象具有与可见光图象不同的特点，它实质上是所观察景物的温度分布，不具有习惯上的可见光图象那样的观察效果。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
