To resolve this problem, we'll reel outwards drive across the bridge to the intermediate surface of variable-speed drive wheel with two wheels of processed into 30 °, the increase in friction with Groove, even if such a belt would not have had; the diameter of 6 mm, spin out to o-rubber belt changed out with Burr corn-cob o-shaped belt; crossing the bridge to another variable-speed drive belt pulley to roll out of the book, two rounds of the belt pulley turned into 1/2 inch, using chain drive sprocket, and fixed machinewe side wall to cross the bridge wheel seat side wall plate processing growth holes for adjust tension pulley and sprockets.

为解决这个问题，我们将分切机朝外传动面传动到中间过桥变速皮带轮的两轮加工成30°的带槽，增加摩擦力，这样皮带即使松了也不会打滑；直径6mm的O型橡胶皮带改成外面带毛刺的聚氨酯O型皮带；过桥变速皮带轮的另一个传动到出书辊的皮带轮，两轮改成1/2英寸的链轮，采用链条传动，再将固定在机器侧墙板的过桥轮座侧墙板孔加工成长孔，可任意调整皮带轮与链轮的松紧。

If this value is significant, it means that the independent variable does contribute to the dependent variable.

如果这个值是重要的，那表示因变量受自变量的影响大。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
