Herein, a series of compounds, BP-C〓-NBD (n=2, 3, 4, 5, 6, 8, 10), was synthesized. Nanosecond flash photolysis, phosphorescence emission and lifetime, as well as photoisomerization reaction of norbornadiene were used to understand the intramolecular triplet energy transfer in detail.

我们设计、合成了以多亚甲基连接的二苯酮与降冰片二烯（BP-C〓-NBD，n=2，3，4，5，6，8，10）系列化合物，利用纳秒时间分辨技术、低温磷光发射、磷光寿命以及光敏异构化的方法，对其分子内三重态能量传递过程进行了详细地研究。

After all, they appeared briefly in some preview videos, and were in the game at some prelaunch community events.

毕竟，他们短暂地出现在一些预览影片，并在发射前的游戏在一些社区活动。

A missile with an imaging seeker could send images back to the launch platform, allowing an operator to positively identify targets, to command the missile to switch from one target to another or to reacquire the true target, if seduced by a decoy.

装备了成像导引头的导弹可将图像回送到发射平台，从而使操作手可以有把握地识别目标，控制导弹从一个目标转向另一个目标，或者导弹在被引诱时，重新获取新目标。

At a White House photo session with Sudanese Vice President and southern Sudan regional leader Salva Kiir Mayardit, President Bush said a truce arrangement must stop Hamas rocket fire once and for all

布什在白宫和苏丹第一副总统和南部苏丹地区的领导人基尔合影时说，停火安排必须一劳永逸地解决哈马斯发射火箭弹的问题。

During uniaxal compression AE test of rock, the noise at ends of the specimen and from the load system are not eliminated efficiently by existing ways.

在岩石单轴压缩声发射实验中，现有的各种排噪措施还不能有效地排除加载系统和试件端部产生的噪音。

Firstly, the model of distributed single-hop fully-connected FH-PRNs for missile systems is developed in this dissertation, which fully describes the physical and link level characteristics of the network. Common-transmitter-based spreading codes protocol and unslotted ALOHA channel access protocol are adopted, considering two types of services, i. e. Unacknowledged Data Packet and Acknowledged Data Packet.

首先，本文建立了战术导弹武器系统分布式单跳全连接跳频分组无线网的网络模型，所建模型充分地反映了网络的物理层和链路层特性，采用了公共码加发射码的扩频码协议及异步非时隙ALOHA信道访问协议，考虑了两类业务的情况，即无应答数据分组和有应答数据分组。

An introduction is given to the ambiguity function of the transmitted waveform, based on which the resolution and the principles for waveform design are analyzed. Combined with bistatic radar, the velation between the resolution and the target positron is discussed.

推导了该雷达发射信号的模糊函数，分析了影响其距离和速度分辨率的因素以及波形参数选取原则，结合双基地雷达的特点，给出了模糊函数与目标位置的关系。

There's also a launch-control mode, which sets the revs at 3000 for a better jump off the line and shifts automatically while at full throttle.

还有一个发射控制方式，确定了转速在3000更好地跳下自动线和变化，而在全油门。

The transmitter takes advantage of the eigenvectors of the SCM of the correlated channels to spread and weigh the signals of each layer. The spatial eigenbeams are formed to carry the signals being spread. The receiver distinguishes the signals from different beams via dispreading operations; therefore co-channel interferences are eliminated effectively.

发射机利用信道空域协方差矩阵的特征矢量，对每一层发射码元进行扩频和特征波束形成加权，形成正交的空域特征波束来承载扩频后的信号码元；接收机则通过解扩处理分离来自不同波束上的信号，有效地抑制了共信道干扰。

It can not only show clearly and accurately the changes of tissues, autopsy and pathology of the brain, but also show the information of the activity of the brain in time without harm. It can be widely used in forensic medicine such as injury gradated evaluation,disability evaluation and cognition in forensic assessment in psychiatry, providing a new method from pure morphological study to morphology-function combination study.

它以脑功能活动时引起的血氧浓度改变为基础，采用不同颜色直接实时地将脑功能变化反映在MR图像上，突破了既往研究脑功能的黑箱技术，以往的影像学检查技术绝大部分是依赖于被检组织形态学的改变，而功能性成像这一领域一直为正电子发射体层摄影(positronemissiontomography，PET)所独有。
