ultra-red radiation

Investigation on the properties of new type ultra-fast radiation detector

新型超快探测器性能研究

The hardness and tensile strength of PVC products could be improved by ultra-violet light radiation.

经过辐照，可大幅度提高PVC制品的硬度及拉伸强度。

DAST is one kind of the most important materials in generating and detecting THz radiation for the reason that it has large optical nonlinear and electrooptic coefficients, low dielectric dispersion, large coherence length and ultra fast response time.

DAST因具有高的非线性和电光系数、低的介电常数、大的相干长度和快的响应时间等优点而在光整流法产生和探测THz波方面存在巨大应用潜力，目前对其研究较多。

Ozone is the earth's barrier against ultra-violet radiation.

臭氧是地球防止紫外线辐射的屏障。

The design method for ultra short baffle with radial leaves is proposed. The stop arrangement and the suppression of the diffracted stray radiation are discussed.

提出了带径向叶片的超短型遮光罩的设计方法，讨论了光阑的安排和衍射杂光的抑制。
