So when the wavelength of the incident light changes, only the position of rhomb-type retarder need to be changed to allow the light to represent oblique incidence in the front of rhomb, and then selecting suitable incident angle can compensate the dispersion phase deviation, and make the same rhomb possess standard λ/4 phase retarder under all different wavelengths.

当入射光的波长改变时，只需改变菱体延迟器的方位，让光线在菱体的前端面上斜入射，适当选取入射角，就可以补偿相位延迟的色散偏差，使同一菱体达到对不同波长都满足λ/4相位延迟。

The colour of the sulphur dioxide/rosaniline complex is determined photometrically at a wavelength of 570 nm.

To conduct such research a new experimental apparatus was established.With this setup the two-photon excitation spectra of Barium and one-photonexcitation spectra of Strontium Rydberg atoms were recorded and identified.The Stark spectra of Strontium atoms showed the "l-mixing" and "n-mixing"features. By changing laser wavelength and external electric field strengthsimultaneously, the scaled-energy spectra of Strontium 〓 Rydberg atomsat constant scaled-energy ε=-3.00,-2.50 and -1.88 were recorded for thefirst time. The experimental spectra were Fourier transformed and yielded therecurrence spectra.

1The scotopic spectral sensitivity curve with its maximum at 490 nm of theround scad shows a relatively heightened sensitivity in the short wavelength regionand a 'shoulder'between 523 nm and 560 nm as compared to the absorption spectrumof the rod pigment.

鲹ERG b波的暗视光谱敏感曲线峰值在490毫微米，和视色素吸收光谱相比较，短波段(小于456毫微米)曲线上翘，长波段也偏高。

1064Nm wavelength laser does not damage skin cells, but if melanin piercing too deep and dense. It will damage fundic cells when the smashed powder was throwing out of our body, if a mass of fundic cells are damaged, scarfskin would lose its self-repaired ability, then scar formed.

1064nm波长的激光本身不损伤表皮细胞，但如果黑色素刺入皮肤过深、过密，在爆炸弹出体外的的过程中会将基底细胞破坏，一旦大量的基底细胞受损，就会使表皮丧失了自身修复功能，也会形成疤痕。

Small aspect change will lead to a big change of the complex amplitude, since, although the variation of the range of each scatterer to radar is very small, it is still large enough compared to the small wavelength and may cause a big phase change.

当视角有微小变化时，虽然各散射点到雷达的距离变化并不大，但相对于微波波长，其相位差的变化相当大，从而使各分辨单元到复振幅有大的起伏，即一维距离像的方向敏感性十分敏感。

Seaquake caused by the tsunami waves also known as Tianjin, its cycle from a few minutes to ranging from tens of minutes, the wavelength usually ranging from 10-10km, so called long waves.

海震引起的海啸又称津浪，其周期由数分钟至数十分钟不等，波长一般可达10—10km，因此又称长浪。
