查询词典 signals

The concept of entropy is applied to define an index on evaluating the abnormal condition. Prediagnosis of machine fault is made using the spectral structure distribution divergence as a criterion, in which the J divergence concept and multi-parameter evalution theory that describe the pseudo distances between the sampling signals and the corresponding standard faulty signals are used.

At this level, the upward projecting signals to higher-located centres and signals that eliciting spinal reflexes are subjected to complex modulatory effects coming from the descending fibers from supraspinal structures and propriospinal neurons through releasing some neuroactive substances, including neurotransmitters and neuromodulalors.

在这里，来自脊髓上结构的下行纤维和脊髓本身的局部神经元通过释放各种神经活性物质，包括神经递质和调质，对痛信号向高位中枢的上行传递和引起脊髓局部反射的过程，起着复杂的调制作用。

EP2 immunostaining was gradually strengthened in the luminal epithelium and glandular epithelium from day 1 to 5 of pregnancy, followed by the gradual reducing of immunostaining on days 6-9. No specific signals for EP2 mRNA were detected in the uterus under delayed implantation, but strong signals were present in the luminal epithelium after reinitiation of implantation.

妊娠第1-5天的腔上皮和腺上皮上EP2免疫染色逐渐增强，到第6天时子宫腔上皮和腺上皮上有强的免疫染色，在随后妊娠第7-9天的子宫腔上皮上逐渐降低。

Repeaters receive signals from one network segment and amplify, retime, and retransmit those signals to another network segment.

重读接收讯号从一个网段和健全， retime ，这些信号转发到另一网路区段。

The echolocation signals at flying, foraging behaviors and food types of 4 endemic species in China were studied. The results were described as followed:(1) Rhinolophus rex has long CF-FM signals, low dominant frequency with the range of 26. 8±0.2kHz, which is the lowest in the recorded Rhinolophidae.

2.4种中国特有蝙蝠飞行状态下的回声定位信号和根据回声定位信号推测出捕食策略和食物类型：（1）贵州菊头蝠回声定位信号为长CF-FM型，能量最大处频率非常低，为26.8±0.2kHz，是已有记载的菊头蝠科中回声定位频率最低的。

The echolocation signals of Rhinolophidae and Hipposideridae are both long CF-FM with 1 harmonic and narrow FM bandwidth. But Rhinolophidae has longer duration, higher duty cycle and lower dominant frequency than Hipposideridae. All the echolocation signals of Vespertilionidae are short FM with 2-6 harmonics and wide FM bandwidth. Vespertilionidae has shorter duration and lower duty cycle than the other two families. There are obvious differences in dominant frequency between different species in this family.

菊头蝠科和蹄蝠科回声定位信号均为长CF-FM型，一般具有1个谐波，调频带很窄，但菊头蝠科的持续时间和能率环明显高于蹄蝠科，蹄蝠科能量最大处频率高于菊头蝠科；蝙蝠科回声定位信号均为短FM型，具有2～6个谐波，持续时间和能率环比其他两科低，调频带很宽，能量最大处频率在种间变化较大。

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。
