In width . to maintain the proportions of the original picture , also select the lock aspect ratio check box 若要维持原有的宽高比不变，还可选中“锁定纵横比”复选框。
The ratio of span - height of an ordinary tie beam is always less 2 . 5 , so the resisting shear is difficult to achieve 由于一般连梁跨高比小于2 . 5 ，使得受剪承载力很难满足。
Alkaline zinc manganese dioxide batteries have been paid much attention to because of high specific energy , specific power and low cost 高比能量和高比功率且价廉的碱性锌锰电池倍受人们关注。
Film 35 mm ; image produced by camera aperture and projected image area , anamorphotic method , lateral compression ratio 2 : 1 and aspect ratio 2 , 35 : 1 35mm胶片.采用变形法按横向压缩比为2 : 1和宽高比为2 . 3
The effect of exit back pressure and length / height ratio of isolator on forebody / inlet flow field is analyzed and discussed in the paper 本文还研究了隔离段出口反压及隔离段长高比对进气道流场的影响。
Moreover , the students in professional high school who hold performance avoidance goal are more than that of normal high school 7普高比职高更加强调成绩氛围，职高学生采取成绩回避目标明显高于普中学生。
Clogging up of the cooling air slits in the turbine blades is primarily caused by ultrafine particles with a high specific surface area 涡轮叶片之间冷却空气缝隙的堵塞主要是因为存在高比表面积的超细粒子。
Coupling beams " failure mode , shear distortion , ductility and energy dissipation were impacted by different shear - compression ratio from 0 . 15 to 0 . 20 是一种值得推荐的抗震联肢墙小跨高比洞口连梁的配筋形式。
