We determined the mitochondrial DNA sequence of S. yangtsekiense and discussed the phylogenetic status of freshwater crabs in Brachyuran according to gene arrangement features and sequence data sets. We also sequenced regions of mitochondrial COI and ND5 genes in order to address the genetic structure of S.

本文以长江华溪蟹为代表，通过对线粒体基因组序列的测定，从基因序列和排列顺序2个方面探讨淡水蟹类在短尾类中的系统地位；并利用COI和ND5 基因的部分序列数据，对我国长江华溪蟹种群的遗传结构进行了初步研究。

Methods Portable bracket of lower limb is composed of two fir panels and support structure. The level of support and the knee flexion is controlled with it. It is used in preoperative high-pressure disinfection, and then trouble limb is placed on the bracket to complete operation of tibia interlocking intramedullary nail.

便携式下肢手术支架由组合在一起的2块彩木板和支撑结构组成，可调节支架的高低和所需要的膝关节屈曲角度；术前高压消毒，术时展开将患肢放在上方，完成胫骨交锁髓内钉手术。

The basic structure of the inflorescence is the cyme (branchlets arising from the bracteole axils, the bracteoles serving as bracts for upper flowers), which can be reduced to one flower with two bracteoles and a bract. Units of dispersal vary considerably (capsules opening with lower part persistent, flower and bracteoles falling together, or cymose partial inflorescences breaking off above bract) and can be characteristic for genera. Several genera possess long trichomes serving dispersal at the base of the tepals.

花序的基本的结构是聚伞花序小枝起因于bracteole腋，散布的单位变化多样(蒴果开裂下半部分的宿存，花和小苞叶一起脱落，或部分聚伞花序在苞片以上裂开并且可以作为属的特征一些属在花被片的基部有长的毛状体用于散布Digera arvensis Forssk吗？

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。

Introducing the Darwin's method of treating x-ray diffraction in crystals into Bragg diffraction for multilayer structure, a series of analytical expressions are obtained, which can be used to calculate the reflectivity, the Darwin's width, the minimum number of periods and the energy resolution.
