系统发生

Photoperiodic counter is an important part of photoperiodic response. It accumulates and stores photoperiodic information contained in a sequence of light-dark cycles.

光周期计数器是光周期反应系统的一个重要组成部分，它累积和储存光周期循环中的光周期信息，当存贮的信息总量超过一个内部阈值时，诱导(滞育和非滞育；有性和无性)就会随之发生。

Thus, a phylogenetic tree is based on a hypothesis of the order in which evolutionary events are assumed to have occurred.

因此，系统树是基于对进化事件发生顺序的假设。

To provide data of floral development for the genus Phytolacca and to have a further insight into the systematic relationships of the family Phytolaccaceae, floral organogenesis of three species in this genus, viz., P.

I can still remember the great thrill it was for me to read the listing of Stan Poley's SOAP II assembly program in 1958; you probably think I'm crazy, and styles have certainly changed greatly since then, but at the time it meant a great deal to me to see how elegant a system program could be, especially by comparison with the heavy-handed coding found in other listings I had been studying at the same time.

我至今难忘自己在1958年阅读Stan Poley写在纸带上的SOAP II 汇编程序时受到的震撼，你们也许认为我有点疯狂，而且从那以后程序设计的风格的确发生了很大的变化，然而在那时候，这些程序令我醍醐灌顶，让我看到即使是系统程序亦能够如此优雅--这份优雅在同时期其他纸带上手工硬编码的程序中鹤立鸡群。

Based on a quadratic separator, a robust reliable filter design method for a class of systems with polytopic type uncertainty is presented against sensor failures.

摘要针对凸面体不确定系统并考虑传感器发生故障的情况，基于二次型分离算子进行了鲁棒可靠滤波器设计的研究。

HACCP is a systematic approach to identify, assess, and control of hazards, it was used to minimize and prevent the pote...

HACCP计划是一个预防食品发生安全问题，监测、控制食品危害的管理系统和工具，它被用来防止、减少、避免、排除可能对食品安全造成的危害。

And these results supported the idea that the activation of the prototypal matters came as a result of automatic processing and the activation of heuristic information in prototypal matters maybe the result of automatic processing. Thus, the two-stage model for learning-testing was designed to make subjects find a solution on their own initiative rather than just receive and comprehend the given answers passively.

通过对行为研究的系统分析，我们认为通过学习-测试的两阶段范式，运用微观发生法，加入原型学习阶段，可以成功催生顿悟，不仅保证了让被试主动去解决顿悟问题，还缩短了&酝酿期&，为采用ERP技术探讨顿悟的脑内时程特点提供了可能。

In the present study, we initially explored the molecular mechanism for S-nitrosylation of PTP1B, a prototypic PTP which controls a diverse array of signaling pathways.

本研究首先在体外系统中以PTP1B为对象(典型PTPs的代表，调控了许多重要的讯息路径)，在分子层次上清楚说明了PTPs 亚硝基化作用发生的机制。

Mucosal pseudomembrane formation may lead to mucosal scarring with loss of function of the involved organ system, as well as esophageal strictures that may occur when extensive involvement of the esophagus exists.

粘膜pseudomembrane的形成可能会导致粘膜瘢痕与功能丧失对所涉及的器官系统，以及食管狭窄时，可能发生的广泛参与食管存在。

In recent years, both HeV and NiV have continued to emerge and reemerge, The epidemic investigation suggested that the virus could be widely present in the Flying foxes, especially Pteropus lylei in Tailand and Cambodia, which are close to China, moreover, the similar enviorment and Flying foxes species、distribution in the south-east area poese a great threat to pig industry and public health of China, based on the above issues, there is a pressing need for diagnostic technologies on the two virus.

为有效防治亨得拉病毒和尼帕病毒在我国的发生和流行，本研究首先利用原核表达系统成功地表达HeV N、NiV N基因以及NiV G一段主要抗原区基因GC，并证实了两种N蛋白的主要抗原区位于C末端约200aa区域。

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".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
