As a fundamental subject of many science departments and engineering departments , general physics , including mechanics , thermodynamics , optics , electromagnetism and atomics , is a required professional course for university students of science departments and engineering departments , making the physics teaching representatively and extensively in bilingual teaching 摘要普通物理（含力学、热学、光学、电磁学和原子物理学）是高等院校理工科大学生必修的专业基础课，是理工科课程的基础课，这使得物理教学在双语教学上既具有代表性又具有广泛性。

The annihilation of the octahedron voids at the tips of fpds was divided two processes : ( 1 ) the oxide on the void was removed by the out - diffusion of oi in the shallow region , especially the oi aroud the void and by the entry of the interstitial si atomics . ( 2 ) the void without oxide shrinked by emitting vacances and the migration of silicon atoms from edge to the bottom of void Fpds端部八面体空洞的消失分为两个阶段： (一)覆盖在空洞各个内壁上的氧化膜由于高温下硅片表面区域的间隙氧原子，尤其是空洞型缺陷周围的间隙氧原子的外扩散及自间隙硅原子的进入，而逐渐变薄直至最终消失。 (二)无氧化膜的空洞，在高温下发出一个个空位，同时八面体空洞周围的自间隙硅原子不断的从空洞的边缘迁移至空洞的底部，使空洞逐渐变浅直至最后消失。
