Interference images are produced by a Michelson interferometer, which used a bromine tungsten lamp as the light source. A Kretschmann prism configuration is used to stimulate SPR. The reflected biochip images are recorded by a CCD camera. Spectral images which are obtained through Fourier transform of the interference images, are analyzed and processed to get SPR curves.

系统以溴钨灯为迈克尔逊干涉仪的光源产生干涉图像，采用Kreschmann棱镜耦合结构激励SPR，由CCD摄像机采集传感芯片干涉图，对干涉图进行信息提取和傅里叶变换得到光谱图，再对光谱图进行分析处理得到SPR曲线。

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。
