The principle and composition of the passive hydrogen maser is introduced briefly,and an application of digital frequency modulation and digital servo to the passive hydrogen maser for improving the performance of the clock is expounded.The final test and analysis of the system are presented and the data indicate that the stability of the present system is much better than that of the original one.

简单介绍了被动型氢原子钟的组成及原理，阐述了基于数字调频和数字伺服的电子电路在被动型氢原子钟上的应用，并给出了设计的最终测试结果及其分析，数据表明该系统的稳定度比原有系统有很大提高。

He is called the Merovingian, and he will not let him go willingly.

oracle在这次对话的结尾已经在告诉neo，在他去source之前的事情都是系统安排的，可是他到了the source以后，他将有改变未来的机会和能力，不要总是相信系统的安排，要相信自己的能力。

The oracle: yes, he disappeared some time ago. we did not know what happened to him until now. he's being held prisoner by a very dangerous program, one of the oldest of us. he is called the merovingian, and he will not let him go willingly.

The correlative analysis was done between PAIs and postoperative outcome. Results: The minimal diameter of right pulmonary artery was found at proximal portion in 62 cases, at middle portion in 22 cases and at distal portion in 34 cases; the minimal diameter of left pulmonary artery was found at proximal portion in 46 cases, at middle portion in 13 cases, at distal portion in 59 cases. The length of stay in ICU, mechanical ventilation time, dose of inotropic drugs correlated well with modified pulmonary artery index better than Nakata index, with Nakata index better than McGoon index.

目前临床上多用McGoon指数、Nakata指数作为形态学指标评估肺血管容量及肺血流情况，一般认为McGoon指数、Nakata指数越大，术后低心排发生率越低，生存率越高，但这些指数有以下缺点：l 左、右肺动脉第一分支处的单点测量值能否反映肺血管的全貌尚有疑问。2 McGoon指数、Nakata指数无法预计术后肺血管的潜在发育能力。3 McGoon指数、Nakata指数都需通过心血管造影后测量获得，价格昂贵，有一定的创伤性，无法系统观察。

With a suitable performance function and an initial control that made the closed system bounded, a serial of controls that made the performances better could be obtained by policy iteration, and ergodic Markov chains were constructed by the state serial with the corresponding feedback control.

在合适的性能指标并能找到一个使系统性能有界的控制的前提下，通过策略迭代可以求出逐步改善系统性能的控制序列，同时得到状态序列在相应反馈控制作用下构成遍历的马尔可夫链。

These four aspects have been involved in prevenient aesthetic system. However, Dessoir have given them more important and systematic meaning.

这四大方面在以往的美学体系中已有涉及，但是德索使之有了更加系统的意义。

This paper discusses the cultural environment of historic city from the ecological point of view,establishing the concepts of cultural gene,cultural species,and cultural ecology,confirming the valuable cultural species which should be paid attention to,especially the rareness and the declining species.

提要 本文从生态学角度研究历史文化名城的文化环境。建立了城市文化生态系统的文化基因、文化物种、文化生态学的概念，确定了历史文化名城中有价值的文化物种，分析了物种在系统中的数量和变化状况。

All signals of of the resulting closed-loop system are globally bounded, and the states of the resulting closed-loop system can converge to a residual set.

得到的闭环系统的所有信号是全局有界的，并且闭环系统的轨线收敛到状态空间的一个残集。

This paper proposes a "Personalize Assignment of Reward Restrictedly" model which is a Multi-Agents System composed of three heterogeneous agents, and uses this model to improve the original reward system in game.

故本论文提出并说明了有限度地个人化分配酬赏机制。利用三种异质性的代理人建构出一个多代理人系统来改变原有的酬赏分配机制。这三种代理人分别由玩家的观点、酬赏的观点与系统的观点来看待每一次的酬赏。
