Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有&盾状心皮&的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出&囊状心皮&的特点。

METHODS: Exposed cutaneous branches rooted in rami posterior nervi spinalis and dominated muscles by exciding the median skin at the back of the rat's neck, given electric stimulation to the muscles by Low-frequency pulse transmitter. The output range was Voltage 0-40 V, frequency 1-111 Hz and pulse width 0-1 000 ms.

切开大鼠颈后正中表皮，显露脊神经后支皮支及其所支配的颈部后外侧肌群，使用低频脉冲发射器对上述肌肉进行电刺激，发射器的输出范围为：电压0~40 V，频率1~111 Hz，脉宽0~1 000 ms。

Of ferns having sporangia that arise from a group of epidermal cells.

Squamate reptiles have a complicated shedding cycle and their epidermis have heterogeneous histological layers, but only the oberhautchen bears the repeating pattern of ornamentation.

有鳞目动物具有复杂的蜕皮循环，表皮层还具有复杂的组织学层次，然而只有最外面的角皮层有稳定的微细结构。

Squamate reptiles have a complicated shedding cycle and their epidermis have heterogeneous histological layers , but only the oberhautchen bears the repeating pattern of ornamentation.

中文摘要：有鳞目动物具有复杂的蜕皮循环，表皮层还具有复杂的组织学层次，然而只有最外面的角皮层有稳定的微细结构。

The results of experiment part4 strongly suggested that, ES derived epidermal like stem cells may have the differentiatial potential of squamose epithelial and skin appendixes, incluing hair follicle, sweat gland and sebaceous gland.

我们的结果强列地提示，ES源表皮样干细胞同时具有分化为角化复层鳞状上皮，毛囊、汗腺、皮脂腺等皮肤附属结构的潜能。

In most plants stomata are located mainly in the lower epidermis of the leaf, where evaporation rates are lower.

在多数植物中气孔主要分布于叶片的下表皮，因为该处的蒸腾作用较弱。

Stomata : mainly at lower epidermis, for gases exchange and water loss by transpiration.

气孔 ：主要在叶底表皮，用作气体交换和水分的蒸发。

Light quality affected the stomatic characteristics in ginger leaves. The upper cuticle stomatic density, stomatic width and stomatal aperture width under green film was the highest than those of others.

生姜生长的光质环境显著影响了气孔形态特征，绿膜覆盖生姜叶片上表皮气孔密度、气孔宽度、气孔孔径宽度较其他处理大。
