A2, in the world, the vast majority of AM points per inch of the number of lines in the dot-matrix, only Germany once in a while the number of dots per centimeter line. 150 line represents the inch 150 x 150 line = 22,500 a number of points, higher numbers, the more business card printing and membership card, the more difficult, making the good paper business card printing and membership card making for behaving as a musician of image quality, the use of more than 300 line number would be closer to the continuous tone of the feeling, on the other hand, are coarse thick wire.

A2、在寰宇上，绝不小众数的AM网不面都以每寸有众少线的不面阵来算，只有德国不常以每公分有众少线筹算。150线表示每寸有150×150线=22，500个网不面，数字越不小不面数越众，制卡和会员卡制作越艰难，在好的纸张制卡和会员卡制作后提下可表示很澈底的影像品格，搁置300线以上的线数不离很挨近不断调的发觉，反之，粗纸不离给用粗网线数。

Experimental results indicate that the B/A value greatly affects the internal Nusselt number and friction factor of the twisted tube because the parameters decrease with the increase of B/A and S/d values, more rapidly with the former, and that the Nusselt number and friction factor of the twisted oblate tube increase respectively by 30%~150% and 20%~50%, as compared with those of the smooth tube at the same Reynolds number and Prandtl number.

实验结果表明：高扭曲比螺旋扁管的管内努塞尔数和阻力系数均随B/A值和S/d值的增大而减小，但随B/A值的增加而减小得更快，B/A值对高扭曲比螺旋扁管的管内传热与流阻性能影响更大；在相同雷诺数和普朗特数下，高扭曲比螺旋扁管管内的努塞尔数为光滑管的1.3~2.5倍；阻力系数为光滑管的1.2~1.5倍。

The experimental results indicate that, over a ranger of tube side Reynolds number and Prandtl number (Re=4000~20000, Pr=6~7.5), the internal Nusselt number and friction factor of spiral-flat tube increased by 30%-150% and 20%-50% respectively compared with smooth tube at the same Re and Pr. The value of friction factor decreases with increasing the value of B/A as well as increasing that of S/de, and the same phenomena can also be observed for Nusselt number.

实验结果表明：管内Nu和f值均随均随B/A值和S/de值的增大而减小，但随B/A值的增加而减小得更快，B/A值对螺旋扁管管内传热与流阻性能影响更大；在相同Re和Pr下，螺旋扁管管内Nu数为光滑管的1.3～2.5倍；阻力系数f是光滑管的1.2～1.5倍。

The grain-leaf ratio showed a periodic oscillation relation to total seedling number in each growing stage, it was decreased with the increasing of total seedling number in earlier winter stage, wintering stage and jointing stage and was increased with the increasing of total seedling number in turning green stage. The grain-leaf ratio was bigger when the total seedling number was 2700000-3200000 plants/hm^2 in earlier winter stage and was 6400000-8200000 plants/hm^2 in turning green stage.

粒叶比与各生育阶段总苗数呈周期性振荡关系，且随着冬前期、越冬期和拔节期总苗数的增加而减小，随着返青期总苗数的增加而增大，当冬前期总苗数在270万320万株／hm^2、返青期总苗数在640万820万株／hm^2时，粒叶比较高。
