Results On CT,of 8 cases.Symmetric hypodense areas of bilaleral thalami and internal capsules were fund in 7 cases.symmetric hypodese areas of bilateral basal gangalia were simutaneosly seen in 5 cases.On MRI,of 5 cases,symmetric Long-T1 and long-T2 signals of bilaleral thalami,internal capsules and basal ganglias were fund in all cases;Thrombi were seen in vein of Galen and oringinal of straight sinus in 5 cases in a period of 3～11 day after the disease came on.It were displyed hyperdensity on CT and short-T1 and long-T2 signals on MRI and disppeared in a period of 14～30 days after the diseases came on.

结果 CT表现为双丘脑、双内囊对称性低密度影7例，同时并有双基底节对称性低密度影5例，MRI表现为双丘脑、双内囊及双基底节区对称性长T1、长T2异常信号5例；5例发病后3～11天内于Galen静脉及直窦起始部可见栓子，CT表现为高密度，MR表现为短T1、长T2异常信号，14天后检查栓子消失。

The advantages ofthe method are both increasing the members of resolving coherent signals in ULA and solving the problems of direction finding in UCA to coherent signals.

该方法的优点是增大了直线阵分辨相干信号源的个数，解决了圆阵对相干信号的测向问题。

There was a trading-off effect in the effects of text signals, which meant that the facilitating effects of text signals on the signaled content were acquired at the cost of memory of the unsignaled content.

本研究的一个重要发现是文章标记效应中存在交易效应现象，即文章标记对标记信息的促进效应是以牺牲未标记信息的记忆为代价获得的。

Joint Time-Frequency Analysis is a new-style theory in Signal-Analysis, which combines the signals' characters in time domain with those in frequency domain. For reflecting the integral character, JTFT possesses good effect in analyzing unstationary or time-changing signals.

联合时频分析方法是一种新型的信号分析理论，它结合了信号在时间域与频率域的特性，反映了信号频率随时间变化的综合特性，在分析非稳定、时变信号方面具有很好的效果。

These Lorenz systems are built, which are relevant and can be switched each other via the choicer. Chaotic synchronization of these systems is realized using same nonlinear feedback control method. The transmitter can be switched discretionarily among several chaotic systems, bring on ceaseless changing of the chaotic carriers in transport channel. In the receiver, the chaotic carriers are retrieved from the received signals, then the information signals are recovered.

构建了有一定关联的两个Lorenz混沌系统，并通过选择器在系统间随机切换；用同一种控制方法既能实现不同Lorenz系统的混沌同步，又能实现相同Lorenz系统的混沌同步；发送系统可以在Lorenz混沌系统间随机转换，传输信道中混沌调制信号也随之不断变化；接收系统将混沌调制信号解调后，即可获取有用信号。

Then, based on the properties of DSTM signals, the new algorithm analyzes the demodulated signals and finishes fine-grained CFO estimation.

并且鉴于差分空时调制信号的特点，对解调后的信号进行分析，估计出残余的载波频率偏差。

Aimed at the difficulty to extract the fault information of a low speed shaft in a large gearbox, wavelet analysis was used to realize the local analysis of signals in a time and frequency domain simultaneously. The signals were dissembled to a sieres of compactly supported wavelet bases non-redundantly and without leaking.

针对大型齿轮箱低速轴故障信息难以提取的问题，采用小波分析方法对故障数据进行处理以实现信号在时/频域的局域性分析，将其无冗余、无泄漏地分解到一组具有紧支撑性的小波基上。

The results show that both methods of wavelet and EMD are effective, while the method based on EMD, which filters signals and eliminates the noise selectively according to spectrum character of decomposition signal, is the optimal method that can sufficiently keep the non-stationary character inhered in signal and provide well auto-a-daptability, flexibility and affectivity and feasibility in filtering and denoising of rock blasting and impact fragmentation signals.

结果表明：采用小波与EMD 2种滤波、消噪的方法都能获得较好的效果，而基于EMD滤波、消噪法是依据信号分解结果的频谱特性进行选择性的滤波和消噪，更能充分保留信号本身所固有的非平稳特征，具有自适应强和灵活、有效的特点，是一种更好的爆破振动信号滤波、消噪法。

The signals were separately processed by means of three kinds of ICA algorithm of MSNR, GOSA and JADE. Some noise processing was interfused into a group of recorded vibration signals and the independent performance index was used to measure the reliability of the modal frequency separated by ICA.

使用MSNR，GOSA和JADE这3种ICA算法分别对信号进行处理；对记录的一组振动信号进行加噪处理；用独立性评价指数衡量了ICA分离模态频率的可靠性。

The experiment results show that the PRI tracker can track signals with constant, staggered PRI and PRI jittered signals with a APRI smaller than 10% of the average PRI.

实验结果表明PRI跟踪器能跟踪上固定PRI、PRI参差和PRI抖动或滑变范围小于平均PRI的10％的脉冲序列。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
