系统发生

The journal well informs the research advances in all aspects of arachnology, including spiders' research, structural analysis, phylogenetic reconstruction, habitats, behavior and the introductions of some new species etc.

该杂志全面提供了节肢动物学各方面的研究进展，包括蜘蛛研究、结构分析、系统发生重建、动植物生活环境、行为学以及一些新种的介绍等等。

The resulting phylogeny indicated that:(1) Araneidae and Tetragnathidae, which build orb webs, are not a sister group in the superfamily Araneoidea;(2) Theridiidae and Linyphiidae, which build nonorb webs, are also not monophyletic, The results also corroborated the independent origins of linyphiid sheet webs and theridiid gumfoot webs;(3) The phylogenetic placement of linyphiid closer to tetragnathid than to araneid implies that the similarities of male palpal organ between linyphiids and araneids may be homoplastic rather than homologous.

结果表明：(1)织圆网的园蛛科和肖蛸科蜘蛛在园蛛总科里不是姊妹群；(2)不织圆网的球蛛科和皿蛛科也不是单系的，进一步证实了皿蛛片网和球蛛网独立起源的观点；(3)皿蛛科蜘蛛的分子系统发生地位与肖蛸科较近而与园蛛科较远表明皿蛛科和园蛛科间雄性触肢结构的相似性很可能是类似而不是同源相似。

For those who are not into this type of awareness, it can and will be very traumatic, because when systems break down, well, Ariana doesn't really want to say these words but all hell will break loose.

对于不是进入这意识那些人，它能够而且将是非常受伤，因为当系统发生崩溃的时候，好， Ariana不是真想说这些话，但是全部的邪恶势力将挣脱出来。

Back pressure valve in the course of precautions are: 1, to avoid system resonance.

背压阀在使用过程中应注意的事项有： 1、避免与系统发生共振。

And both symmetry-breaking bifurcation point and symmetry-recovering bifurcation point were calculated.

并计算了系统发生对称性破缺分岔点和对称性恢复点。

So during the collection of fault sample data and checking data, the paper sets up the mathematics model of control system first. We cause all kinds of fault in the control system, then collects a variety of fault data. After unitarily dealing, the fault data server as the sample data of training neural network. At the same time, according to the collection of checking data, it examines whether the trained neural network have the function of fault diagnosis.

在故障样本数据及检验数据的采集过程中，首先建立了控制系统的数学模型，人为地让控制系统发生各种故障，从而采集到各种故障数据，经过归一化处理后，作为训练神经网络的样本数据；同时，也采集检验数据，用以检验训练出的神经网络是否能够起到故障诊断的作用。

Critical load, which is defined as the highest deposition of acidifying compounds that will not cause long-term harmful effects to the ecosystem, indicates the sensitivity of an ecosystem to acid deposition.

酸沉降临界负荷是指不致使生态系统发生有长期危害影响的最高酸沉降量，它表示生态系统对酸沉降的敏感程度。

Use bifurcation curve and analyze the effect on voltage stability by static load model,propose that critical voltage decrease with the constant impedance ratio increasing.

使用分岔曲线，分析了负荷静态模型对系统电压失稳临界点电压值的影响，得出系统发生电压失稳时临界电压值随负荷模型中恒阻抗负荷比例的增加而降低，并对北京电网进行实例分析。

Black start of power systems is a very important problem in the restoration strategyafter a complete blackout.

电力系统黑启动是系统发生全停电后恢复策略中的一个重要问题。

The relationship between temperature and pressure of the ternary ammonia water lithium bromide solution in generation process and COP of the system were determined in the range of 15-80℃ and up to 1.5 MPa.

测定了氨－水－溴化锂三元吸收式系统发生过程中的温度－压力关系，计算了系统的性能系数。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
