周期的

The overriding, powerful, indivisible, predominant benefit of the Adaptive Development Life Cycle is that it forces us to confront the mental models that are at the root of our self-delusion.

适应性开发生命周期的最重要的，强大的，不可分的，有影响的益处就在于它迫使我们去面对思想中基于我们的错觉而产生的模型。

A grating function and a groove function are introduced to determine the structure of a concave grating. Basic ideas for the design of a flat-field concave grating with three stigmatic points are proposed. As a proof of the usefulness of these design approaches, image conditions of the grating with three stigmatic points are developed which concise with other published results and they are more general than those obtained from holographic gratings.

采用与分析三维光栅相类似的级数展开法给出了二维集成凹面光栅的球差、彗差的计算方法，计算中用光栅函数和槽面函数来描述具有任意形状和任意变化周期的光栅，提出了一种具有三个无像差点的平面场型凹面光栅的设计方法，利用该方法推导了三点无像差光栅的成像条件，与文献中用其它方法获得的结果相一致，该结果与全息光栅的成像条件相比，更具一般性。

Various turbopump configurations will be discussed at a conceptual design level, utilizing the disciplines involved in the design selection process, the "state of the art" of rotating machinery when each design took place, and the engine cycle requirements that influence the turbopump design.

各种涡轮泵的配置将讨论的概念设计水平，利用学科所涉及的设计甄选过程中，"国家最先进的"旋转机械时，每个设计发生的，和发动机的要求，周期的影响涡轮泵的设计。

In between naturalness and unnaturalness there is a mist that continues to grow stronger and broader.

一走进会场右边，首先映入眼帘的是林俊兴董事长今年度油画新作〈自然迷雾〉，作品内涵为：自然演化到最近的百万年大乔木取得优势，出现了以十万年为周期的冰河现象，但最近一万年崛起的人类，先是以农业文明站在大乔木的这一边，阻绝了回温的过程，而又以工业文明站在地球与动物的一边，让温度快速上升而走回近百万年的规律，但这种人为演化强烈的加在自然演化之上，自然就有些不自然。

Conceptually, the most obvious sample point within a fundamental period is often referred to as the pitch mark. Usually pitch marks are selected as the local maxima or minima of the audio waveform. In the previous example of pitch determination for the tuning fork, we used two pitch marks that are local maxima. On the other hand, in the example of pitch determination for human speech, we used two pitch marks that are local minima instead since they are more obvious than local maxima.

在观察音讯波形时，每一个基本周期的开始点，我们称为「音高基准点」（Pitch Marks，简称 PM），PM 大部分是波形的局部最大点或最小点，例如在上述音叉的范例中，我们抓取的两个 PM 是局部最大点，而在我的声音的范例中，由於 PM 在局部最大点并不明显，因此我们抓取了两个局部最小点的 PM 来计算音高。

To investigate the stantant changes of Ⅰ、Ⅱ、Ⅲ and PG expression of mandibular condylar chondrocytes stimulated by the different static compressive stresses, so that to make a primary understanding of the relationship between the differentiation and dedifferentiation of condylar chondrocytes and different compressive stresses; to investigate the stantant changes of the content of DNA of mandibular condylar chondrocytes stimulated by the different static compressive stresses, so that to make a primary understanding of the relationship between proliferentiation and apothesis of MCCs and different static compressive stresses.

观察单层培养的髁状突软骨细胞加载不同静压力后，Ⅰ、Ⅱ、Ⅲ型胶原以及蛋白多糖表达的变化，探讨不同静压力对髁状突软骨细胞的分化及去分化的即时效应；观察单层培养的髁状突软骨细胞加载不同静压力后，其增殖、凋亡及细胞周期的变化，探讨不同静压力对髁状突软骨细胞增殖及凋亡的即时效应。

The aims of the writers study is to observe the effects of its inducing apoptosis and influencing cell cycle by treating esophageal carcinoma cases with sodium cantharidate before operation.

本研究通过术前应用斑蝥酸钠注射液，旨在观察其诱导食管癌肿瘤细胞凋亡、对肿瘤细胞周期的影响，并初步探讨两者的关系；通过测定p53、bcl-2基因表达在应用斑蝥酸钠后的变化，初步探讨斑蝥酸钠治疗食管癌的分子机制；同时测定应用斑蝥酸钠后的免疫功能变化，以期对斑蝥酸钠对机体的影响做出较全面的评价。

Here we show that the phase of the annual cycle of surface temperature over extratropical land shifted towards earlier seasons by 1.7 days between 1954 and 2007; this change is highly anomalous with respect to earlier variations, which we interpret as being indicative of the natural range.

假设这一温度记录的前一部分是由自然变化所主导的，那么最近的趋势似乎高度异常：陆地上的温度向早先的季节有1.7天的偏移，而变化周期的幅度（即夏季和冬季之间的温差）在这一时期降低了。

Finally, the Markov chain is introduced into the supply chain study based on the uncertainty of the supply chain and the willing of the supply chain enterprises to cooperate with each other. The methodology of supply chain operation cycle based on Markvo chain is presented. The operation model of multi- stage netlike supply chain is established. The application of this model is indicated by analysis of concrete casestudy.

最后，针对供应链运作中的不确定性以及供应链企业间彼此合作的意愿，将马尔科夫链引入供应链研究中，提出了一种基于马尔科夫链的链式供应链运作周期的算法；在此基础上，构建了基于马尔柯夫链的多级网状供应链运作模型，并通过具体案例的分析求解对模型的应用做了说明。

The human Rad9, a homologue of yeast Schizosaccharomyces pombe rad9, is a member of the Rad family of checkpoint proteins. It is involved in detection of DNA damage, cell cycle arrest, and DNA repair. Although considerable information about hRad9 and its function has been accumulated, its behavior in malignant cells has not been examined.

人类的Rad9蛋白为Schizosaccharomyces pombe Rad9蛋白的同源蛋白，其为checkpoint rad genes产物中的一员，是一个在演化上具有高度保留性的蛋白。hRad9在细胞内扮演著许多重要的角色，包括侦测DNA的受损、调节细胞周期的进、执 DNA 的修等等。
