并发的

Limited by traditional database technology, the spatial data and attribute data were stored dividually. With the transfermation of GIS application to the Distributed Management System, concurrency control, data sharing and network communication become the new problems.

受以往数据库的限制，空间数据和属性数据是分开存储的，随着GIS应用向分布式管理系统领域的转移，在数据共享、网络通信、并发控制等方面出现了许多难以解决的问题。

The category is designed to include a group of children with severe mental retardation (IQ below 50) who show major problems in hyperactivity and in attention, as well as stereotyped behaviours. They tend not to benefit from stimulant drugs (unlike those with an IQ in the normal range) and may exhibit a severe dysphoric reaction (sometimes with psychomotor retardation) when given stimulants. In adolescence, the overactivity tends to be replaced by underactivity (a pattern that is not usual in hyperkinetic children with normal intelligence). This syndrome is also often associated with a variety of developmental delays, either specific or global.

因有下述特徵则作此诊断：出现注意力不集中及过动行为的重度智能不足（智商低於 50 ）；给予兴奋性药物治疗并不能改善此类儿童的情况，反而可能会有情绪低落反应在少年期少动行为常取代过动行为（这种情况在正常智商的过动儿童并不常见），同时常并发特定或全面的发展迟滞。

Background and objecbive: Standard cardiopulmonary-cerebral resuscitation fails to achieve restoration of spontaneous circulaton in ~50% of normovolemic sudden cardiac arrest s outside hospitals and in essentially all victims of penetrating truncal trauma who exsanguinate rapidly to cardiac arrest .

在战争或创伤中，躯体贯通伤致出血性心跳停止的病人，即使在快速补充血容量的情况下，常规心肺复苏使其幸存的几率也几乎是零，在紧急开胸的情况下，当患者并发多发性损伤，特别是膈下损伤时，其死亡率也接近100%。

However, current WSN applications in Precision Agriculture all adopt the traditional client/sever model, data are sent from the source to the destination, because of hugeous data, high concurrency and strong signal interference in Precision Agriculture and the extremely limited sensor network resources, such client/sever model hampers WSN applications in Precision Agriculture.

然而当前无线传感器网络在精细农业中的应用都采用传统的客户/服务器模型，数据从源端发送到目的端，受精细农业中数据量大、并发性强、信号干扰强及传感器网络资源极端受限的影响，这种客户/服务器模型阻碍着传感器网络在精细农业中应用，导致了当前传感器网络大规模成功应用于精细农业的例子很少。

For instance, long-running C extension functions in threaded applications must release and later reacquire the global interpreter lock, so as to allow Python language threads to run in parallel.

例如，带线程的应用中，执行时间很长的C扩展函数必须释放全局的解释器锁，并在后来再次获取，这样才能让Python语言的线程并发运行。

With the far and wide sweeping popularity of the Internet and smart-card based E-commerce over Internet, much recent research attention has been paid on the security threats of zero-knowledge protocols when they are executing in concurrent and resettable settings.

伴随着Internet以及Internet上基于智能卡的电子商务的广泛普及和大规模应用，零知识证明系统在并发及可重置环境中运行时所遇到的安全问题最近得到了高度重视和深入的研究。

Furthermore, since it is a well-known open problem whether constant-round resettable zero-knowledge systems with concurrent soundness for NP exist in the generous BPK model or not, our this work makes a significant step for finally solving this important open problem.

更为重要的是，由于对所有NP-语言常数轮且并发可靠的可重置零知识系统是否在秃公钥模型中存在是一个著名的公开问题，我们此方面的工作对于解决此一重要公开问题亦迈出了重要一步。

To achieve constant-round concurrent/resettable zero-knowledge, several famous computational models have been introduced, among which the bare public-key model is the weakest and also the most appealing one.

为了得到常数轮的并发及可重置的零知识系统一些著名的计算模型已经提出来，其中最弱同时最令人关注的是秃公钥(Bare Public-Key)模型。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
