A silent communications system in which nonaural carriers, in the very low or very high audio-frequency range or in the adjacent ultrasonic frequency spectrum are amplitude- or frequency-modulated with the desired intelligence and propagated acoustically or vibrationally, for inducement into the brain, typically through the use of loudspeakers, earphones, or piezoelectric transducers.

一个沉默的联系是不承载听觉，在非常低或非常高音频范围里，或在邻近的超音速的频谱中，这是广阔的-或带有期望的智能并且传播声学的频率调节或振动，为了刺激大脑内部，典型的是通过利用扬声器，耳机，或压电式换能器。

Evidence suggests that when northern snow forced teleconnection is generated in this season, anomalous zonal/meridional circulations are revealed in east Asia-western Pacific band; with east Asia-Pacific teleconnection formed, anomalous zonal circulation is dominant over that band; the anomalous vortex of north Pacific origin moves southwestward and, r...

研究发现当北半球夏季出现积雪强迫型遥相关时，东亚－西太平洋地区既存在异常纬向环流，也存在异常经向环流；而当出现东亚太平洋型遥相关时，东亚－西太平洋地区以异常纬向环流为主。分析还发现源于北太平洋的异常涡旋在向南传播的过程中，先取西南路径，在到达菲律宾东部以后折向东南。

Based on delay-time transformation, the differential equation with varied coefficient was solved by taking into consideration the boundary, radiation and continuum conditions.

在两种不同材料的联结处或存在局部损伤时，都会引起局部材料的非均匀性，但波在非均匀介质中的传播问题的研究，由于数

The single-celled trypanosome that causes African sleeping sickness, transmitted between humans and animals by bloodsucking tsetse flies, goes through several different stages in its life cycle.

引起非洲瞌睡病的细胞锥虫在人与动物之间通过吸血舌蝇进行传播，在它的生命周期中会经历几个不同的时期。

In order to clearly recognize the geophysical response of carbonate reservoir,based on preliminary recognition of Ordovician carbonate reservoir under the basal surface in Tahe oilfield,some regular vug models and random arranged vug models were designed and built. The variable-grid finite difference method was used to simulate the seismic wave propagation in these models. Then,the seismic records of the models were analyzed and the effect to seismic reflections caused by vug is studied. The impact rule of regular vug scale and random arranged vug density on seismic attributes was obtained.

为了研究碳酸盐岩储层的地球物理响应特征，在对塔河油田奥陶系风化面下碳酸盐岩储层初步认识的基础上，利用随机介质建模技术，设计并建立了一系列碳酸盐岩储层规则孔洞和随机孔洞模型，并应用变网格有限差分法对地震波在孔洞模型中的传播进行了正演计算，对模拟得到的地震属性进行了分析，研究了孔洞对地震反射特征的影响，获得了规则孔洞尺度以及随机排列孔洞密度对地震属性的影响规律。

As a general excitation source, planar wave is often used in research on scattering problems.

电磁波的远场可以视为平面波，在目标电磁散射特性的研究中常常被作为激励源，给出了柱坐标系下完整的总场-散射场区的连接边界条件，从而模拟了平面波在自由空间的传播。

BP neural network based on adaptive UKF is introduced in this paper for the standard BP neural network has slow converges,local minimum value and weak generalization ability.It can train weight of BP and improve the efficiency of BP without linearization by using the frame of Kalman filters and adaptive factor to adjust the variance of dynamic model.

1引言1986年，Rum elhart和M cC lelland等人在多层前向神经网络模型的基础上，提出了误差反向传播学习算法(BackPropagation简写BP)，该算法是目前在神经网络中应用最广泛的算法，它解决了多层前向神经网络的学习问题[1]。
