Methods and Results— Using a micro–single-photon emission computed tomography small-animal imaging system and a Food and Drug Administration–approved radiotracer ([indium 111] oxyquinoline, 111In-oxine), we demonstrate here that monocyte recruitment to atherosclerotic lesions can be visualized in a noninvasive, dynamic, and 3-dimensional fashion in live animals.

方法和结果——采用微单光子发射计算机断层摄影术的小动物成像系统和美国食品药品治理局认同的放射性示踪剂（111In-oxine），我们证实动物体内单核细胞向动脉粥样硬化损害处的聚集能够通过一种非侵入性，动态的，3维方式进行可视化观察。

On the other hand, from the point of view of work manner, thedetecting systems can be classified two kinds: the active and the passive systems. Althoughthe passive detecting system can\'t get so much information as the active one, it has itsspecial characteristic. For instance, the passive system is immune to the radar clutter. It issecreting and has no electromagnetic pollution due to none of radialization. The passivesystem also has excellent capability of detecting the target covered with the stealth material.

从工作方式来看，探测系统还可分为主动和被动两种方式，虽然主动工作方式可以获得关于目标的更多信息，但是被动工作方式也有其不可替代的特性，如不受闪烁效应的影响；由于本身不发射电磁波，因而没有电磁污染及工作比较隐密；对覆盖吸波材料的目标探测能力很强等。

SAR is a kind of high resolution radar and it will be influenced by the atmosphere disordering behaved as the random changing of the three angles such as drift,roll and pitch.

合成孔径雷达是一种高分辨率的主动式微波成像雷达，它通过天线向目标发射微波，经目标反射的回波携带有目标的表面信息，经信号处理机处理后可在显示器上成像。

RIT control. The receiver incremental Tuning control is used to fine tune to the received singal .This is used in USB and LSB modes to obtain maximum clarity of reception,and in CW mode to control the pitch of the beat note. The RIT Control can tune the receive frequency about 2.3 KHz. This control will not transmit frequency, or the frequency display, but will change the receive frequency.

RIT control ：收信机微调旋钮是用微调调整使你能收到被认为是标准的信号，在USB和LSB模式使用可以获得最清晰的接收，在CW模式可以控制节拍的音调，这个RIT控制可把接收的频率调整约2.3KHz左右，它不影响发射频率和显示频率，但将改变接收频率。

The direction that the echoes come from shows the compass bearing of the target.

由目标所反射的无线电波回迹的方向能确认其方位角，电波发射和折返的时间可以确认其距离，每英里需时1.24*10-6 S，目标的仰角可被用以确认其高度。

The direction that theechoes come from shows the compass bearing of the target. The time it takes for the radio pulse to reach the target

由目标所反射的无线电波回迹的方向能确认其方位角，电波发射和折返的时间可

Training the dog: Function switch dial in the "OFF" position, With the Ultrasonic generator toward dog, Pressed the button "TRAINING CALL" at Back, which will be issuing 23KHz ultrasonic of 100dB strong, with gestures and password, your dog can be trained to do some specific action.

训狗：功能开关拨在&OFF&位置，超声波发射头对住狗狗，按动背面的&TRAINING CALL&按键，即会发出23KHz 约100dB的超声波，配合手势和口令，可训练您的爱犬做一些特定的动作。

Based on the optimization control theory, it detruded a modulus proportion guidance law of end guidance process.

在设定的初始条件下，对预警机引导战斗机发射空空导弹的飞行过程进行了仿真，并对相应的结果进行了分析，给出了可视动态飞行过程。

Firstly, we simulate the signal received by OTHR in each antenna according to the real working condition, and save the signal datum in file. Secondly, we develop the signal processing program and the visual users interface. Thirdly, we utilize the simulation system to analyze Linear Frequency Modulated Continuous Wave OTHR system and Binary Phase-coded Continuous Wave OTHR system. Finally we compare the performance in suppression of interference of these two kinds of OTHR system.We achieve two aims in this simulation system.

本文首先根据OTHR的工作环境模拟OTHR各个阵元接收的回波信号，并将其保存为数据文件；然后根据OTHR的系统结构，编写信号处理程序，并给出可视化用户界面；最后利用OTHR仿真系统，对二相编码连续波和线性调频连续波这两种发射波形的OTHR作抗干扰性能分析。
