皇家馬德里結束了他們4年的未奪冠的經歷，在星期天當他們贏取了第30次奪得西甲冠軍，以一次真正的激烈比賽中以3 - 1回擊馬洛卡后在伯那鎢取得勝利Radiation effects have been investigated up to - 30 dpa by the heavy ion irradiation simulation and positron annihilation lifetime techniques in the home - made modified 316l stainless steel and the commercially available stainless steel and tungsten, which are used as the beam window materials for the spallation neutron source in accelerator driven radioactive clean nuclear power system ( ads ). their radiation resistance properties are compared
本工作採用重離子輻照模擬和正電子湮沒壽命測量技術研究了加速器驅動潔凈能源系統（ ads ）散裂中子源束窗材料鎢、普通不銹鋼和國產改進型316l奧氏體不銹鋼在0 30dpa輻照劑量范圍的輻照效應，並對它們的抗輻照性能作了比較。The piezoelectric actuator becomes one of the most prospective components because of its outstanding advantage. but the hysteresis and creep character of the material restrict the development of this actuator. new stable characteristic tungsten bronze piezoelectric actuator was adopted as driving component in this article, we develop the anti - hysteresis control method through contrasting the crystal structure of the tungsten bronze actuator with which of the perovskite actuator, at the same time corresponding software and hardware were studied in order to prove the validity of this control method, and then demarcated the other characters of the actuators through lots of experiment results
本研究選用了性能穩定的硬性鎢青銅型壓電陶瓷驅動器作為驅動元件，從壓電陶瓷驅動器遲滯產生的微觀機理入手，通過對比硬性鎢青銅型壓電陶瓷驅動器和軟性鈣鈦礦型壓電陶瓷驅動器的晶體結構，研製出壓電陶瓷驅動器抗遲滯驅動方法，設計了相應的軟硬體裝置以從實驗結果上證明這種方法的正確性，並對其他影響定位精度的因素進行了特性標定實驗。The 20 years, when the chinese opening and reform went deeper, was also an important period for the development of tungsten industrial system and tungsten processing in ganzhou
