With the development of science and technology, more and more oxide crystals are synthesized by more and more advanced technique, the new oxide crystals are incessantly synthesized and the new characters of oxide crystals are incessantly founded. corundum dopped with impurity not only is cherished because of it ' s beautiful appearance, but also is used in the fields such as electrotechnics, mechanism, laser, the optic apparatus and the underlay of semiconductor. sapphire dopped with ti3 + is the best material of the tunable solid laser. zno crystal is material of the direct gap semiconductor ( the width of forbidden band : 3. 37ev ). the excited emission in zno crystal at room temperature has been found, so the ultraviolet luminescence in zno semiconductor can be acquired at room temperature
含有少量雜質的剛玉晶體（ - al _ 2o _ 3 ）不僅由於其色澤艷麗成為人們珍愛的名貴寶石，而且由於它具有的優異性能，被廣泛應用於電工、機械、激光器，光學器件和半導體襯底材料。鈦藍寶石是目前最優異的固體寬帶調諧激光材料，用於製作飛秒脈沖可調諧激光器。氧化鋅晶體是直接帶隙寬禁帶半導體材料（禁帶寬度3 . 37ev ） ，現已發現具有室溫下受激發射特性，有可能實現室溫下半導體紫外發光。 -
Especially, his opinions on the reformation of the state ownership and the establishment of the market mechanism broke through the forbidden zone of the traditional economics
他的關于所有制改革特別是國有制改革的理論和實施步驟，以及關于運用市場經濟體制以替代原有的指令性計劃經濟體制的理論和政策、策略都具有重大的突破性和明顯的超前性。 -
The latest domestic and foreign achievements on anti - skidding surface of asphalt pavement were collected in this paper, and the major problems on grade design in our country were also thoroughly analyzed. according to systematic analysis on anti - skidding mechanism of asphalt pavement surface, the paper introduced the concept of reference point and forbidden zone of superpave technology to control grade curve " s trends and discussed the influence on pavement surface " s ability of anti - skidding and durability
論文匯集了國內外瀝青路面抗滑表層的最新研究成果，深刻剖析了我國現有抗滑表層級配設計的主要問題，在此基礎上，通過對瀝青路面抗滑機理的系統分析，引入superpave技術的控制點和禁區概念來控制抗滑表層混合料級配曲線的走向，研究了該技術對路面抗滑能力和耐久性的意義。 -
The research used questionnaires and follow - up interviews and conducted investigations in wenniute county to do some research on the ecological compensation of grazing forbidden, then analyzed some measures to establish and fulfill the ecological compensation mechanism in grazing forbidden areas
通過對內蒙古翁牛特旗退牧還草項目實施的實證分析，探討建立與完善退牧還草地區生態補償機制的途徑與措施。 -
With the introduction of the dopants, the effective mass of carriers was changed and the seebeck coefficient was increased. at the mean time, the dopants reduced the forbidden energy gap, which changed the carrier concentration and thus increased electrical conductivity. by calculating the forbidden energy gap and electrical conductivity of mg2si specimen doped with different amount sb, the mechanism of transference changed abruptly at 625k
在mg _ 2si熱電材料基體中摻雜te 、 sb元素后，在結構中引入了缺陷，增大了體武漢理工大學博士學位論文系中載流子有效質量，提高了seebeck系數;降低了體系導電活化能，提高了電導率，同時也降低了熱導率。
