timber size

First of all, through analyzing the size and process requirements of the prepared timber, it determines the composition and layout of the chipper which is NC energy-saving parallel to the grain, including automatic feeding and discharging mechanism and the main cutting bodies.

通过对加工木材的尺寸和工艺要求的分析，确定了数控节能顺纹削片机的组成和布局，这其中包括切削加工机构、自动进料机构和自动出料机构的设计。

Every piece of timber was planed, cut to size and stained with cedar preservative.

每根木材都被刨平了，切割成一定尺寸，并涂上了雪松防腐剂。

Compared to natural forests, plantation grew fast, yielded well, developed conveniently, gained efficiency early and the timber size and quality are more stable.

与天然林相比，人工林具有生长快、生产量高、开发方便和获得效益早、木材规格及质量较稳定等特点。

In addition , mortise holes were made on the full-size timber, and resonant frequencies measured sequently.

结果显示, 共振频率随榫槽数之增加仅略为减少.

Dead branches or knots in different sizes of tree was studied and different branch development phases of growth, suppression, death and self-pruning was analyzed to evaluate the effect that knot size and distribution impact on timber quality.

研究了不同大小树木的死枝和节子大小及其变化规律，分析了枝条的生长、被压、寿命和自然整枝过程，评价了节子大小和分布对木材质量的影响；
