Shrinkage of cement - based materials and the shrinkage - compensating effect of expansive agents 水泥基材料的收縮與膨脹劑收縮補(bǔ)償作用探討
The feedback control is introduced to compensate effects of both errors of identification and iterative learning , so the control system can get better robustness and control precision 在此引入反饋控制是為了補(bǔ)償辨識(shí)和迭代學(xué)習(xí)的誤差,以增強(qiáng)被控系統(tǒng)的魯棒性,提高控制精度。
In this thesis , by simulating the director alignment , using the characteristics of optical transmission , taking jones matrix we calculate the transmittance of the lcd . by theoretically studying to compensating - film from different aspects , single film and double films , we get that the double - film - compensation has nice compensating effect , especially put the two films in the two sides of lc layer 本文通過模擬液晶盒中指向矢的排列,利用偏振光在其中傳播的特性,采用瓊斯矢量方法計(jì)算出光學(xué)透過率;通過對(duì)不同情況下補(bǔ)償膜(單層、雙層)理論上的研究,得出雙膜補(bǔ)償具有良好的補(bǔ)償效果,尤其是將兩層膜分別放在液晶層兩側(cè)。
