此激光預警器的特點是靈敏度高、視場寬、測向精度高，且虛警率極低。Abstract : one of the unsolved problems of the high power application of high temperature superconductors is how to lower the energy dissipation induced by flux motion. due to the extremely high anisotropy, small coherence length and weak pinning potential, the mixed state phase diagram which is tightly related to the flux dynamics becomes very complicated. a brief account is given of the field induced crossover of criticalities of energy dissipation, which has been observed in our recent sensitive electromagnetic measurement
文摘:高溫超導體在強電方面應用的關鍵問題是如何克服磁通運動所造成的能量損耗.由於存在極強的各向異性、短的相干長度和小的磁通釘扎勢，因此與磁通運動緊密相關的混合態相圖變得很復雜.文章綜述了根據一系列靈敏的電磁測量所觀察到的磁場誘導的能量耗散行為的轉變The density of its field emission catelectrode tip is about 24000tip / mm2, the onset emission voltage is 0. 5 ~ iv, the backward voltage is larger than 25v, the current of single tip is 0. 2na, the sensitivity is 98. 5mv / bar
其場致發射陰極錐尖陣列密度達24000個mm ~ 2 ，起始發射電壓為1 5v ，反向電壓25v ，當正向電壓為5v時，單尖發射電流為0 . 2na ，壓力靈敏度為98 . 5mv bar 。The several ones that have more lager sensitivity to embankment settlement are found out. then, aimed at the traditional three - layer bp network ' s shortages : easily getting into local minimum value and slow convergence, the modification combined momentum method with self - adaptation study velocity is made, and one improved bp network is put forward. finally, according to the results from above sensitivity analyses, the nonlinear model main parameters of each natural layer in roadbed are approximately rectified using the improved bp network technology founded on its stronger nonlinear mapping capacity and the settlement measurements
採用非線性有限元程序，對鄧肯-張模型中8個參數與路堤沉降的關系進行了詳細分析，找到了影響沉降的主要參數；接著，針對傳統的三層bp網路具有收斂速度慢、易陷入局部極小點等不足，對其進行了修正，提出了改進的bp神經網路模型；最後，根據上述靈敏度分析結果，基於改進的bp網路模型較強的非線性映射能力和前期沉降實測資料，對路基中各天然土層的非線性模型主要參數進行了反分析修正； （ 4 ）路堤沉降計算一維法中考慮應力歷史、側向變形的研究。The affective intercourse between teacher and student in the classroom chemistry teaching means that teacher and student should cherish affection for each other. that is, the teacher should intentionally encourage and affect the students in s positive affectionate manner, to invoke sympathetic responses from the students, so that the students may feel that they are having a positive, stable and deep inner experience of affection for chemical science, that they are having a thrilling experience in the " " most independent, most happy and even perfect state ", that they are investing a deep affection in the chemistry learning, and that they are at their best and more clever, more sensible, more wise, more potent and more fine than ever. only in this way can a teacher achieve the best result of education - to make affection on ability of the students
化學課堂教學中師生情感交流是指教師和學生彼此把自己的感情供給對方，即教師在教學過程中有意識地以積極的情感去教育、激勵和感染學生，讓學生從中得到肯定的反映，從而達到以培養學生建立一種指向化學科學，穩定的、深刻的、積極的內心體驗；使學生對化學的學習由體驗產生震撼心靈的感應，讓學生處于「最自主、最喜歡、最幸福、最完善」的時刻；使學生以極度關懷的情感傾注于化學學習之中；使學生能處在自己能力發揮的頂峰，使其覺得此時此刻比其它時刻更聰明、更敏感、更有才智、更強有力、甚至於更優美；使情感成為學生的力量、成為學生的一種能力，從而使教學達到極致。分享友人
