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。

In spite of these guidelines, good writing is not formulaic, so that there can be no ultimately decisive criteria to determine the relationship between the essay and the grade.

尽管有这些准则，但良好的写作不是公式化的，因此不可能有任何最终决定性的标准，来确定论文和分数的关系。

Inoculation of leaf on Helminthosporium Maydis Nisk and observation of anther and pollen and fertility restoration-retention identification indicated that JnA should be classified into group S of cytoplamic male sterility. At the same time, fertility observation of F2 and microscopy identification of F1 pollen through I-KI dyeing confirmed this conclusion.

首先对玉米细胞质雄性不育系JnA进行小斑病菌接种鉴定，同时对其花药、花粉形态观察，通过恢保关系鉴定，F2育性分离观察及F1花粉碘液染色镜检，初步确定JnA属于S组细胞质雄性不育。

The sister-group relationships are strongly supported between Petrosaviaceae and the remaining monocots (except for Acoraceae and Alismatales s.l.), between Dioscoreales and Pandanales, and between Commelinales and Zingiberales in the combined analyses of two genes and three genes.

继无叶莲科之后分化的类群形成两个大的分支：一支是由露兜树目和薯蓣目构成，二者形成姐妹群关系；另一支是由天门冬目、百合目和鸭跖草类复合群组成，三者之间的关系在单个序列分析和联合分析中不稳定，需要进一步扩大取样范围来确定。

By this constraint, the inner parameters, motion parameters of the cameras and the similarity invariants of trapezia can be linearly determined using some prior knowledge on the cameras or the trapezia.

基于这个约束关系，利用摄像机内参数的知识或梯形相似不变量的知识，可以线性确定摄像机的内参数、运动参数和梯形的相似不变量。

The chemically enhanced primary treatment of low concentration domestic wastewater was researched by jar-test without coagulation aid dosing and pH conditioning. The optimal coagulant dosage was determined and the effect of coagulant on the removal of both CODs and CODd was discussed.

提要 通过烧杯试验，在不加助凝剂、不调整pH的条件下，研究了化学强化一级处理对低浓度生活污水的处理效果，确定了最佳投药量，探讨了絮凝剂对悬浮性COD及溶解性COD的去除关系。

The research by co-authors Wong, Kraus, Erika Skoe, Nicole Russo and Tasha Dees represents a new way of defining the relationship between the brainstem -- a lower order brain structure thought to be unchangeable and uninoled in complex processing -- and the neocortex, a higher order brain structure associated with music, language and other complex processing.

脑干曾被认为是不能改变的和在复杂过程中不涉及的低级中枢结构。而新大脑皮层是和音乐、语言以及其他复杂过程有关的高级中枢结构。这项研究的共著者Wong、 Kraus、 Erika Skoe、 Nicole Russo 和Tasha Dees描述了一个新的途径来确定脑干和新大脑皮层之间的关系。

The relations between the potential difference and the discharging time when the discharge current is a step function as well as a step function containing high frequency vibrations, the relations between one-dimensional and two-dimensional spark locations and potential difference based on the thin wall model and the thick wall model have been studied.

仿真研究了放电电流为阶跃函数以及含高频振荡时电位差与放电时间的关系；基于薄壁模型和厚壁模型，仿真研究了电极下表面一维放电点位置和二维放电点位置与电位差的关系；对于确定的电位差，仿真研究了放电点位置的分布情况，说明两点输入不能唯一地检测出放电点位置，从而引入四点输入检测的思想。

The registration involves such steps as registration plane scanning,establishment of registration table ,section plane scanning,recognition of registration substance and registration of all sections.

一种不需要附加定标硬件系统的定标方法是根据各超声断层中定标物与目标物相对空间位置关系，通过定标平面扫查、建立定标表、断层平面扫查、识别定标物、定标各断层等超声断层定标过程，来确定各超声断层的空间相对关系，以达到断层标定的目的。

If you are not already part of an extended family in these cultures, or you do not have a close friend there, you should consider devoting time to developing close contacts. In these cultures, bonds once formed are longlasting and are taken as indications of trust and loyalty.
