電影技術. 8mms型電影膠片錄音用磁帶和錄音磁頭縫隙.位置和寬度尺寸According to the experiment of influences of fiber structures and the width of edge channel on flow filling, it was found that even a small gap ( l or 2mm ) between the preform and the mold edge could also disrupt the flow pattern, which evidently changed the local permeability of preform. the filling process was simulated using the permeability for different edge width predicted by a. hammami or poiseuille model, which shown good agreement with the experiment results
實驗研究了纖維鋪層結構及流道縫隙的寬度對充模流動的影響，發現在纖維預成型體和模具壁間存在的較小的縫隙也會對邊緣的流動產生干擾，進而影響增強材料主體的滲透；對于不同的縫隙寬度，分別根據a . hammami模型和poiseuille模型預測邊緣等效滲透率，並進行充模過程數值模擬，與實驗結果吻合較好。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。By combining the conventional log data with the data on imaging logging, core, drilling - log and production test, etc., and on the basis of carrying out various additional conduction corrections for resistivites, the fracture opening may be calculated by use of the difference between the resistivities of dual laterallog ; the fracture porosity can be estimated according to a simplified dual laterolog interpretation formula ; and the fracture permeability may be acquired in light of the experimental relation between the fracture widths and the fracture permeabilities
將常規測井資料與成像測井、巖心、錄井、試油等資料相結合，在對電阻率進行各種附加導電校正的基礎上，利用雙側向電阻的差異計算裂縫張開度，根據簡化的雙側向解釋公式計算裂縫孔隙度，根據裂縫寬度與裂縫滲透率實驗關系求解裂縫滲透率。As the most widely used type of slot antennas, waveguide slots arrays have the advantage of tight structure, easily controlled aperture distribution, and wide band for the nonresonant waveguide slots antennas, which make it be one of the preferred form in antenna domain of high efficiency and low side - lobe
縫隙天線在現代天線設計中有著重要的地位，而波導縫隙天線又是縫隙天線中應用最為廣泛的天線形式。波導縫隙天線有結構緊湊、口徑幅度相位分佈容易控制和頻帶較寬（行波式縫隙天線）的特點，成為了高效率、低副瓣天線的優選方案之一。分享友人
