此所用於分析之外部非体节形质计有：尾叉长、头长、上颚长、吻长、眼径、背鳍基底长、臀鳍基底长以及吻端到前鳃盖骨后绿、背鳍起点、腹鳍起点、臀鳍起点等11个形质。

The primitive characteristics include long tail with more than 20 caudal vertebrae, which are surrounded by thin rod-like extensions of the zygapophyses and chevrons, and the fifth toe bearing two long digits, whereas the derived characteristics include an elongated skull with antorbital and nasal openings fused into a large nasoantorbital fenestra, long cervical vertebrae with reduced or absent cervical ribs. The length ratio of the wing metacarpal to the humerus is between the basal pterosaurs and pterodactyloids.

它既具有原始类群的特征：比如尾长，多于20节尾椎椎体，且尾椎椎体由极度加长的、纤细的前后关节突及脉弧所包裹，构成一僵硬的尾部，第五脚趾具有两个长的趾节；又具有进步类群的特征：比如头骨加长，鼻孔和眶前孔愈合为一大的鼻眶前孔，颈椎椎体长，没有或者颈肋退化；翼掌骨与肱骨的比率介于原始类群和进步类群之间。

The results indicate that the tailrace tunnel has a good effect on air cooling and dehumidification in summer, and that the parameters of outlet air in the tailrace tunnel are mainly influenced by the temperature of tail water rather than by the parameters of outdoor air and the terminal air parame...

测试结果表明，夏季运行时无压尾水洞对引入空气有良好的降温除湿效果；在无压尾水洞足够长的条件下，尾水洞末端引风参数主要受尾水温度的影响，而受室外空气参数的影响很小，尾水洞出口空气接近对应尾水温度的饱和状态。

The results of the analysis to complete 18S rDNA and partial 28S rDNA D 6-7 domain sequences of 30 collembolan species supported the monophyly of Poduromorpha and Symphypleona, Entomobryoidea is not a monophyly, familia Neelidae should be separated from Symphypleona. The situation about the superfamilia of Tomoceroidea and the familia Neelidae need further studies. The results of the further analysis to complete 18S rDNA and nearlly completely 28S sequences of 4 Protura, 6Collembola, 5 Diplura, 5 Insecta, 10 Crustacean, using 1 Myriapoda and 1 Chelicerata as outgroups indicated that Protura, Collembola and Diplura are monophy, respectively, Protura and Diplura have the nearest realationship, they make sister groups with Collembola and all of them assemble with Insecta to make a monophy cluster of Hexapod; The results support the monophy of Pancrusracea, Crustacean is not a monophy cluster and the realationships between them with Hexapod need further reseachers.

对我国的14科27属30种跳虫的18S rDNA全序列和28S rDNA部分序列(D6-D7)的基因信息数据进行分析，结果支持原目、愈腹目的单系性，长角目不形成单系群，支持短角科从愈腹目中分出，但鳞总科和短角目的分类地位有待于深入分析探讨；进一步比对4种原尾虫、6种跳虫、5种双尾虫、5种昆虫和10种甲壳动物的18S rDNA全序列和28S rDNA全序列，以1种多足动物和1种螯肢动物为外群，进行系统关系分析，结果显示：原尾纲、弹尾纲、双尾纲分别为单系群，原尾纲和双尾纲优先聚为一支，然后和弹尾纲构成姐妹群，以上三类又和昆虫聚为一支，支持六足动物的单系性，支持泛甲壳动物，但甲壳动物并未形成单系，其各类群和六足动物之间的亲缘关系尚须进一步确定。3。

The results showed that the shape of whole talus looked like a tortoise.Most of the talus had talar cauda(97%),and its cauda had long、middle、short types,the fracture of t alar cauda were 52 cases(6.8%).

The calling and copulation behaviour of Ancylis sativa Liu had a dielperiodicity.The female moths began to calling at the first day and increasedto 100% at the second day,then the percentage of calling decreasedgradually from the third day to the fifth day,only 16.7% of females showingcalling behaviour at the sixth day.The effect of environmentaltemperature on calling behaviour of Ancylis sativa Liu was studied duringadult life at 16℃,21℃,26℃ and 31℃.The result showed differenttemperature during adult life affected significantly the calling behaviour ofvirgin females.There was considerable variability in the calling patternsamong the different temperature groups,the higher the temperature was,thelater females called,the shorter the calling behaviour lasted.The copulationbehaviour of Ancylis sativa Liu can be divided into following squence:female calling,male responsing,male approaching female,hairpencil displayingand copulating.

枣粘虫求偶和交配行为研究结果表明，在光周期为14L：10D、温度为21℃下，越冬代枣粘虫雌蛾的求偶高峰期为黑暗期6.0-8.0小时，求偶活动以羽化后1-3天表现强烈，第二天求偶百分率高达100％，第4天开始，求偶百分率下降，到第6天仅为16.7％；环境温度对枣粘虫雌蛾的求偶活动有明显的影响，随着温度的下降，求偶高峰期明显提前，求偶高峰期的持续时间变长，在21、26、31℃下，求偶百分率接近或达到100％，在16℃下，仅为43％；枣粘虫的交配行为可分为雌蛾求偶、雄蛾反应、雄蛾接近雌蛾、打开味刷及交配成功等阶段；交配活动也以羽化后前3天表现强烈；第1、2代在黑暗周期中的交配高峰期比越冬代推后1-2.5小时；越冬代枣粘虫的交尾持续时间多为3-4小时，第1、2代比越冬代短；越冬代交尾前期多为2-3天，第1、2代多为1-2天，少数羽化当天便可交尾；雌雄成虫均有多次交尾习性，雄蛾最高交尾6次，平均3.3次，雌蛾最多交尾3次，平均1.5次，在田间自然条件下，大多数越冬代雌雄成虫只交尾1次，第1、2代交尾次数有所增高，第1、2代成虫交配率明显高于越冬代。
