横切面

In the paper four aspects have been studied:(1) tree and distributing, belonging to the correlative contents of the dendrology,(2) the macroscopical character in virtue of magnifier and entitative microscope observing the three sections (cross section, radial section and tangential section );(3) the microcosmic character, in virtue of light microscope observing slices.

本文从以下四个方面进行了研究：(1)树木及分布，树木学方面相关的内容；(2)木材宏观特征，借助扩大镜和实体显微镜，在木材的三个标准切面，即横切面、径切面和弦切面上进行观察；(3)木材微观特征，借助光学显微镜观察切片。

The methods of computing for similar coefficient were Discriminance of Minimal Difference of Parameters, Discriminance of Limen of Tree Compositive Character and Synthetic Weight Similarity of Parameters. The contribution of all parameters were considering as same for DMDP and DLTC, but it estimate s the similarity between parameters according to the limen for DLTC. DMDP was based on the principal component analysis for wood transverse section micrograph characters and computing the similar coefficient according to the contribution of every parameter.

其中最小差值差数判别法与树种综合特征阈值法是将每个特征参数对木材横切面显微图像特征的贡献率视为一致，只是树种综合特征阈值法是以阈值的大小来判断特征的相似性，而综合加权相似法是建立在对木材横切面显微图像特征参数的主成分分析的基础上，根据每个特征参数的贡献率大小计算相似系数。

Some, of course, are running obliquely and therefore are cut tangentially in relation to their full length.

低倍镜下，肌束走行方向不同，可见不同的肌束不同的切面，有横切面，纵切面，也有斜切面。

An image of the posterior fossa in the transaxial plane is obtained by angling caudally from the plane used to visualize the ventricular atrium.

Herbacium were isobilateral leaves, and those of G. hirsutum and C. barbadense were dorsiventral leaves. The reciprocal F〓 of cross G. arboreum×G. herbacium were also isobilateral leaves, while reciprocal F〓 cross of G. hirsutum×G. barbadense were also dorsiventral leaves. The quadrispecific hybrids F〓 were isobilateral leaves, regardless of their cytoplasms. The structures of the leaf stalks and the stems were analogous to each other among the four cultivated cotton species except their diameters varied with species.

四个栽培棉种及其种间杂种F〓的形态学和细胞遗传学观察四个栽培棉种的植株、叶片、茎杆以及花器等器官都有明显的差异；叶片、茎杆以及叶柄的横切面结构观察结果表明，两个二倍体栽培棉种的叶片横切面构造为等面叶，两个四倍体栽培棉种却均为背腹叶；F〓正反交的叶片也为等面叶，F〓正反交F〓仍为背腹叶，而它们的四元杂交种均为等面叶；四个栽培棉种的叶柄和茎的横切面结构基本一致，只是直径形状和和维管束多少的不同，四元杂种的叶柄和茎的横切面结构的差异不明显。

Suber The cork cells are seen as 14 polygons, show a honeycomblike arrangement in tangential section and resemble a brick wall in transverse and radial sections.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
