with the development of satellite navigation communication,antenna is a very important unit,performance of the satellite navigation communication system is affected by it partly.a new type of bifilar helix for satellite navigation communication system is introduced,and the traving-wave bifilar helix is analyzed briefly.meanwhile,the design and the test results are given.the results show that the antenna possesses excellent circular hemispherical beam with wide angle circular polarization and better impedance match,and has a compact structure and high integration.it can be applied in caps systems successful.

小 摘要：随着卫星导航通信技术的迅速发展，天线作为卫星导航通信系统中的重要部分，在一定程度上决定着卫星导航通信系统的性能。介绍一种用于卫星导航通信系统的双臂螺旋天线，讲述爬行波式螺旋天线的设计过程，并给出最终测试结果。结果表明，该天线具有优良的圆对称半球波束，良好的广角圆极化特性和优良的阻抗匹配特性，其结构简单、紧凑，为通信入站回传提供了一种优良的选择。

Pointing to the feature that the strata developed controlled by palergeomorphy,reef bank grew upward and sea level relative variability,then on the basis of synthetically analyzing Hthology and logging curves features,and applying the theories of sequence stratigraphy,divided Lianglitage Formation into TST and HST from bottom to top,and 3-4 parasequence sets,8 parasequences,and 11 members.furthermore, recognized shelf margin reef,grain bank, shelf margin bioherm and interbank sea these four facies and 12 subfacies.

针对上奥陶统良里塔格组地层的发育主要受古地理、礁滩体向上营建和海平面相对变化控制的特点，在进行岩性特征、测井曲线特征综合分析的基础上，应用层序地层学原理和方法，将良里塔格组自下而上划分为海侵体系域和高位体系域两个体系域，3～4个准层序组、8个准层序，细分为11个小层。并发育棚缘生物礁、粒屑滩、棚缘生物丘、滩间海4种相，12种微相亚相。

Two kinds of water-soluble biomimetic chitosan derivatives with a phosphoramide linkage between glucosamine and choline were prepared through Atherton-Todd reaction under the mild conditions, including zwitterionic phosphorylcholine bound chitosan and acetyl-phosphorylcholine bound chitosan with positive charge. The interaction between chitosan derivatives and calf thymus DNA were inversigated by UV alsorption spectra and circular dichroism spectra.

采用Antherton-Todd反应制备了两种水溶性的磷酰化壳聚糖仿生衍生物：两性的N-磷酸胆碱磷酰化壳聚糖和带正电荷的N-乙基磷酸胆碱磷酰化壳聚糖，并用紫外吸收光谱和圆二色光谱研究了两种胆碱磷酰化壳聚糖衍生物与小牛胸腺DNA的相互作用。

The result shows that in total 75.6% species are under the "10 × rule", 80.5% species possess unique DNA barcode sequences by which they could be identified. On the other hand, 19.5% species (including 8 species of Buteo) are difficult to be distinguished by DNA barcoding.

结果显示，75.6%的猛禽符合10×规则，且80.5%的猛禽均具有独特的DNA条形码可作为物种鉴定的依据，另有19.5%的猛禽（鵟属8种猛禽）由于种间差异太小，DNA条形码对它们的识别鉴定存在一定局限。

objective to elucidate the choice of three defferent ways as well as the clinical efficacy in the treatment of pilon fracture and different damages of skin and tissue.methods 29 cases were treated with calcaneum bone traction and small splinting,23 cases were treated with internal fixation,11 cases were treated with external fixation of ilizarov.results all cases were followed up for 8～31 months (15.3 months average).according to helfet criterion,the results were evaluated as the total excellent and good outcome accounted for 90.5％.conclusion the key point of treatment is rational selection of three defferent ways in the treatment of pilon fracture according to the typle of pilon fracture and different damages of skin and tissue.

目的 探讨pilon骨折的三种不同治疗方法临床适应证及其疗效评价。方法对2000年2月至2006年3月间治疗的63 例pilon骨折患者进行回顾性分析。其中开放性损伤15 例，闭合性损伤48 例。根据骨折类型与周围软组织损伤程度，分别采用三种不同治疗方法：跟骨牵引加小夹板固定组(29 例)均为闭合性骨折，内固定组(23 例)，外固定器组(11 例)。结果所有患者均获得随访，随访8～31个月(平均15.3个月)，骨愈合时间8～14周，平均10周。按helfet疗效评价标准，本组优良者57 例(90.5％)，其中ⅰ型骨折优良者26 例，ⅱ型骨折优良者15 例，ⅲ型骨折优良者16 例。
