High purity SiO2 single crystals with polished surfaces were irradiated with 600 keV, 2 MeV, 4 MeV and 95 MeV Ar ions. The ion irradiated experiments were performed at the 320 kV high voltage platform (IMP, Lanzhou) and the HIRFL-SFC facility in Lanzhou. In Fig.1, PL spectra of silicon dioxide irradiated with 600 keV, 2 MeV, 4 MeV and 95 MeV Ar ions were showed. PL peaks located at 445 nm (F2 color center) were increased in Fig.1(a) samples irradiated with 600 keV Ar ions, the intensity of emission band achieves a maximum value when irradiation dose is up to High purity SiO2 single crystals with polished surfaces were irradiated with 600 keV, 2 MeV, 4 MeV and 95 MeV Ar ions.

摘 要:一谈到小学美术课,很多人会认为很简单,不就是老师在黑板上画,学生在下面模仿画吗?有这种想法的就大错特错了,因为,现今的小学美术课教学不只重视学生模仿画的能力,更注重培养学生通过美术课程来表达自己内心的情感世界,通过美术教学来达到美育的培养。小学美术不单是学画、仿画,更重要的是创造中画。因此,美术课教学不能只是教师画、教师讲,而应该在教师的指导下,学生说出自己内心的想法,画出自己的真情实感,
