通过三类弯管形式压损试验，发现了短半径弯头在一个较大料气输送比范围内均产生最小压损；

By means of the pressure loss in three kinds of bend configuration. it is found out that the short radius elbows appear to yield the lowest pressure loss in a wide range of mass over air ratio.

首先假定输送比，初定气流速度，由农业技术要求确定排种量，从而确定风量，计算得到管道的直径。

First we presume feeding rate, ascertaining the velocity of air current, ascertaining the feeding quantity by farm technical demand and ascertaining wind quantity, calculating the diameter of pipe.

而且有哈维、伊涅斯塔、法布雷加斯和阿隆索这些人为这位射手输送炮弹，他肯定能得到比理论上跟多的机会。

And with players like Xavi, Iniesta, Fabregas and Alonso delivering the killer passes, he's sure to get more than his fair share of chances.
