2.Design, making and test of super short-focus and wide-angle CID TV lens
3.Study on PAB/PET Nematic Liquid Crystal By Wide-Angle X-Ray Diffraction Method
4.Wide-angle reflection and refraction seismic has been success fully used to image zones beneath high velocity layer.
5.Because wide-field lens are adopted in MEE,output images have serious distortion.
6.Get a finder about the same angle of view of the taking lens, or a little longer.
7.Priority 4 - For abstracts, sharp throughout the frame from wide angle to telephoto with the aperture stopped down (f/8 or smaller).
8.Today such mirrors are familiar at convenience stores or blind driveway entrances because they reveal a wide-angle view on the world.
9.From the resolution charts which were gained different Tc temperature from the determination of PPS SAXs and WAXS, one can calculate the smallest value of PPS crystallization speed (t1/2) which is 0.47 min and corresponds to Tc temperature 189℃.
10.The behaviour of melting and recrystallization of irradiated polyethylene has beeninvestigated by using differential scanning calorimetry(DSC),small angle X-ray scattering(SAXS)and wide angle X-ray diffraction(WAXD)techniqties.
