Interest rates and bank reserve requirements were both increased and the people ' s bank of china also announced a widening of the trading band for the renminbi
中國人民銀行還提高了息率和存款準備金率，同時又公布放寬人民幣匯率的波動區間。 -
Quantum confinement effect was observed in the films by measurements of absorption spectrum of ge - sio2 films. the widening of optical band gap of the amorphous films seems to be related to the function of the quantum confinement on the impurities or defects in the films
光吸收特性研究表明，因量子限域效應，對于ge - sio _ 2薄膜觀察到較強的光吸收和光吸收邊隨ge顆粒尺寸變小而藍移的現象。 -
Secondly, because the band of the traditional microstrip antenna is very narrow. and the isolation can ’ t meet the requirement when the coaxial - line feeding is used to realize the dual polarization. the following work lays heavy stress on analysis of the way of widening the bandwidth and developing the isolation of the antenna
傳統的微帶天線帶寬較窄，採用普通同軸線饋電實現雙極化的時候，隔離度不能夠滿足天線的要求，所以在接下來工作中，重點分析了微帶天線頻帶展寬和隔離度改善的方法。 -
The way of widening the band is realized by employing the inverted parasitic patch and the thick and low dielectric constant substance. with this treatment, the relative band of the antenna can be widened up to 20 %. and by adopting the way of two h - slots arranged in a “ t ” configuration, the isolation is improved
微帶天線的頻帶展寬通過採用倒懸寄生貼片和較厚的低介電常數的介質來實現，經過這樣處理后的天線帶寬可以達到20 %以上;而隔離度的改善則是採用了兩個h形縫隙排列成「 t 」型結構。 -
At the same time, the possibility of using nonlinear optics in widening the detecting wave band of hartmann - shack wavefront sensor is exploringly discussed. adaptive optics guarantees the beam quality of laser projecting system. beam cleanup, atmospheric turbulence compensation and correction of any disturbance and fabrication error in the light way are required to promise a near diffraction beam, but normal adaptive optics system can only correction one of them
自適應光學進行光束大氣傳輸波前畸變校正時，要求系統必須能進行光束凈化和校正大氣湍流造成的波前畸變，並且能夠同時有效地克服發射系統製造誤差、重力變形以及光路內部氣體擾動的影響，得到接近衍射極限的輸出激光光束。
