弦切面

结合木材组织构造总体特点，本文重点分析了横切面上管孔、树脂道，弦切面上木射线形态特征。

It mainly analyzed the morphological characteristics of pores and resin canal on transverse section and wood ray on tangential section on the basis of wood structure .

弦切面上木射线与轴向薄壁组织形状、大小均不相同；

The shape and size of wood ray is different form that of longitudinal parenchyma ;

在木材弦切面可见条纹。平切单板-地板、板。板材-家俱、槛、板。

Stripes sometimes noticeable on flatsawn face . Easily worked . Sliced veneer-flooring and wall . Sawn lumber-furniture , door-sills and flooring .

（100yT）/（100yT）的比值，可以用来予示在干燥期间是否会在弦切面上出现干裂。

The value of the ratio of ( 100-yT ) / ( 100-yT ) might be used to predict whether or not dry checks would occur on the tangential surface during drying .
