本文研究结果可为进一步研究激光散斑法测量纳米流体中纳米粒子的运动，以及开发新的动态纳米粒子光测方法提供理论和实验依据。

Conversely, another set of observers—some with enthusiasm, others with apprehension—regard him as a crypto-right-winger, poised to shed his cloak of moderation when he crosses the threshold of Number 10. This camp points to the service he rendered to Norman Lamont, a former Tory chancellor: Mr Cameron was Mr Lamont's adviser in 1992, when Britain humiliatingly withdrew from the European exchange-rate mechanism, as Mr Brown often reminds him. And Mr Cameron co-authored the 2005 general-election manifesto.

然而，另外一些或态度激烈或不免担心的观察人士把他看成是秘密右翼分子，正准备等卡梅隆入主唐宁街后揭开他温和的外衣，理由在于卡梅隆曾是托利党前财臣诺曼·拉蒙特的下属：卡梅隆1992年是拉蒙特的顾问，当时英国不光彩得从欧洲汇率机制中撤出，这一点布朗经常提醒他。2005年卡梅隆也参与了大选宣言的编写工作。

What happened, of course, was that when the starship reached the threshold of light speed, it also reached that boundary between "normal" space and hyperspace.

当然，所发生的情况是，在飞船的速度接近于光速时，那也就到达了"正常的"空间和超空间的交接之处。

MethodsIts effect on sleep was observed through the experiments of sleep induced directly,prolonging sleeping time induced by pentobarbital sodium,affecting sleeping rate under the threshold hypnogenesis dosage of pentobarbital sodium,shortening sleep delitescence induced by tobarbital sodium.

方法通过直接睡眠实验、延长戊巴比妥钠睡眠时间、戊巴比妥钠阈下催眠剂量实验和缩短巴比妥钠睡眠潜伏期实验观察灵芝提取物对睡眠的作用。

The inestigators defined subthreshold bipolar disorder as recurrent hypomania without a major depressie episode or with fewer symptoms than required for threshold hypomania.

研究者把轻度躁狂复发而没有严重的抑郁发作或者比轻度躁狂阈值要小得多的症状类型定义为亚型双向精神障碍。

The concentration-response curves for ATP with and without preapplication of hypotonicity showed that preapplication of hypotonicity shifted the curve downward; maximal amplitude of IATP with hypotonicity decreased by 25.26±2.41%, while the threshold value remained unchanged; the EC50 value of the two curves were very close(1.19×10-4M vs 1.33×10-4M).

3在低渗透压(260mOsm)环境下，ATP-激活电流的浓度反应曲线明显下移；阈值和最大反应浓度不变，EC50为1.19×10-4M，与单独加ATP时的1.33×10-4M基本一致；而最大反应浓度时的ATP电流幅值减小了25.26±2.41%(n=6)。

We propose a dynamic identity authentication scheme through a theorem about relative prime numbers, which can prevent replay attacks from taking place. In addition, we present a threshold signature scheme without a trusted party by use of joint secret sharing technique. Finally, the security flaw in an enhanced password authentication scheme is pointed out and the security of an enhanced key agreement protocol is analyzed.

首先基于一个关于互素数的定理设计了一个动态身份认证协议，该协议使攻击者不可能通过回放攻击来假冒用户；利用联合秘密共享技术设计了一个无可信中心门限签名方案；最后，分析了一个改进的身份认证协议存在的安全漏洞，以及一个改进的密钥协商协议的安全性。
