单向性的

To support secure group communications in resource constrained wireless sensor networks, We propose an efficient and scalable key management scheme which only uses symmetric cryptographic algorithms and hashing function. This scheme can achieve forward and backward security.

At present, the domestic and international attitudes toward SA8000 standard of experts and scholars differ, someone thinks that this standard complies with law of social development, producing has objective necessity; Someone thinks this standard narrow-mindedness and one-sidedness with height, with distinctness and one-way, it is not a fair and rational standard.

目前，国内外专家学者对SA8000标准地态度不1，有人认为该标准是顺应社会发展规律的，产生具有客观必然性；有人认为该标准具有高度的狭隘性和片面性，带有鲜明的单向性，不是一项公正合理的标准。

Regard pursueing "Spiel" of freedom as the starting point, adopt the tactics jeered at, talked in professional jargon, through is it construct to conciliate to traditional subversion of literature, revolt tradition and classics. Embody in theindividual free psychology by "there is no regular following one"s benting and write the experience of life at first, come from compatibly the writing in the form of pluralism.

通过欲望化的本色表达和关注日常生活体验来解构深度，单向度平面地展示&当下&生活；用&戏仿&和&拼贴&的游戏性文本策略制造喜剧性的反讽效果和零碎意象的堆积，拨开严肃的、神圣的缪糕糕意义，让人看到生活最本真的状态；开放互动性的结构打破了作者中心，将读者吸引到创作中来，个人自由叙事得到一个最广阔的相容空间，并由此产生新的文本—&超文本&，为读者提供了一种阅读的自由和精神的自由。

Methods: On single-plane and biplane DSA images (including cases with normal ventricular wall motion,hypokinesia and insufficient mixing of contrast medium in ventricular cavity) the area-length method and videodensitometry method were used to calculate the volume and EF respectively.

结果：双向造影的长度-面积法EF测量值与实际值无显著性差异(P＞0.05)；单向造影的测量值在局部室壁运动减弱时差异显著(P＜0.01)；视频密度测量法在室腔内造影剂混合不均时测量值有显著差异(P＜0.01)。

Resultantly, the individual warm/cold events in ENSO cycle appear to be partially locked to the annual cycle, and also exhibit obvious irregularity both in amplitude and in lasting time.

本文第四章研制设计了一包含海洋表面边界层和大气辐合反馈过程的热带太平洋海气耦合异常模式，进而利用该模式对ENSO循环进行了较为真实的模拟，通过对模式ENSO循环的演变特征及其形成机制的细致分析，建立了-ENSO循环的非线性分析模式，并提出了ENSO循环形成的一种更为客观的理论，指出：1）和观测事实类似，模式ENSO循环确实涉及了三种主要时间尺度过程即LF、QB和AC，其中LF为3-4年主周期振荡，QB占总方差10～20%；2）ENSO循环的正反馈机制是不稳定海气相互作用过程，且这一不稳定过程的发展在暖态中明显强于冷态；3）ENSO循环的负反馈机制在冷暖态中表现不同，在冷态消亡过程中，这种负反馈过程主要表现为西边界反射产生的时滞效应，但在暖态消亡过程中不存在类似的时滞效应，其负反馈过程主要表现为在海气耦合不稳定充分发展时伴随的赤道两侧冷水上翻过程的加强以及非线性过程的衰减作用抑制了不稳定的发展并最终使得系统回复至冷态；4）ENSO循环的3-4年主周期振荡是一非线性系统的自激振荡现象，其形成是线性系统的本征模即准两年振荡通过非线性机制产生的周期加倍所致，其中&单向性&大气辐合反馈加热过程对其形成至关重要；5）虽然年循环过程对ENSO循环形成没有本质影响，但它可明显影响ENSO循环的具体振幅和位相，使得ENSO对季节循环有明显的&锁相&特征，并且也使得ENSO循环在振幅大小和时间长短方面呈现出明显的不规则性。

When the magnitudes and directions of the electric and magnetic dipoles were matched, the radiation in backward and sideward direction was obviously restrained.

当TEM喇叭天线与低频补偿回路形成电偶极子和磁偶极子满足匹配条件时，天线低频辐射的单向性将得到提高。

The changing tendency of books formation from the traditional unilaterality of information transfer to multidirectivity of design form is inquired into.

从我国不同时期书籍形态构成的演变中，探索由传统书籍形态信息传递的单向性向书籍形态设计构成多向性的变化趋势。

On the contrary, although our country has made great efforts in this field in recent years, there still remain many problems in both institutionalisation and practice. For instances, the performance measurement is not properly designed and the related practices are missing the critical legal support.

反观我国，尽管近年来已在政府绩效评价方面做出了很多努力，但目前，无论是在政府绩效评价的相关制度还是具体实践上都存在很多问题，如缺乏法律制度保障、评价主体具有单向性和唯一性、指标体系设计不合理，等等。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
