According to the shape of head, the glandular hairs were divided into capitate and pehate glandular hairs.

根据腺毛头部形状可把腺毛分为盾状腺毛和头状腺毛，二者均发生得很早，它们的原始细胞都来源于原表皮，一般在茎尖第1和第2片叶原基的原表皮细胞以及茎的1～2节间原表皮细胞中开始发生。

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。

Results Cuticular papillates,glandular hairs,peltate scales,and non-glandular hairs presented on the leaf epidermis of C.paliurus.Anomocytic stomata were confined to the lower epidermis.Large cluster crystals existed in the uppermost layer of palisade cells.Midrib included one closed vascular system and one additional vascular strand.Secondary veins are semicraspedodromous and form marginal loops,tertiary veins are percurrent,quaternary veins form orthogonal or polygonal areoles filled up by branched and freely ended veinlets.

There were no statistically differences between the 8th~ 14thday, the 15th - 21th day post-BC and the control group. During the rt~24tkday post-BC , pycnosis degeneration or necrosis neurons of the locus cerebral cortex, dorsal hippocampus, dentate fornix were significantly increased, then decreased gradually, but recovered to normal by the 24thday after BC, and especially in parietal cortex and piriform cortex the necrosis neurons were significantly increased than temporal cortex , and there were no statistically difference berween the left and the right side. Pycnosis degeneration or necrosis neurons in the brainstem reticular formation were markedly increased in the 4thday after BC, and there were no statistically difference among the other groups and the control group.

结果表明秋海棠属植物叶表皮形态在属内组间具有较大的相似性，表皮细胞为多边形或近多边形，垂周壁平直或弓形，大多数种类表皮细胞内具有晶体，气孔器仅分布于下表皮，且以不等型为主。

In order to know the evolutionary relationships between false vein, ISC, and VSC in Pteridaceae, 19 grnera and 82 species in Pteridaceae were sampled in this study; silica deposition types, ordinary epidermal cell morphology and veinal epidermal cells morphology of these species were surveyed. On the other hand, a convenient method was developed for this goal. In this method, a tabletop SEM with backscattered electron detector accompanied by post-cooling method was used.

为进一步探讨凤尾蕨科假脉、脉间矽异形细胞与脉上矽异形细胞之间的关系及其於凤尾蕨科内的演化，本论文选取19属82种的凤尾蕨科植物，观察其叶表面之二氧化矽堆积型式、一般表皮细胞形态以及脉上表皮细胞形态；同时，也开发出利用侦测背向散射电子之桌上型扫描式电子显微镜配合后冷却技术(post-cooling method)之快速检测法，该方法利用背向散射电子讯号强弱与平均原子数(average atomic number， Z number)之相关性得到矽异形细胞与一般表皮细胞具有明显对比之影像。

本研究证实了两种HO同工酶在大鼠前列腺腹侧叶的分布： HO-1分布于前列腺腺上皮细胞和纤维平滑肌间质，而HO-2主要分布于腺细胞。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
