本文最后计算了一种典型的规则排列得城市环境中街道得电波传播路径损耗,并与文献中得实测及计算数据进行了比较,然后进一步对矩形、圆柱型建筑物城市小区电波传播进行了分析计算。 - It can be used in any complex environment , can locate all paths from transmitter to receiver which avoid redundant calculation , and it is a standard 3 - d forecast model ; in addition , it is a point to point ray tracing method based on specular theory which do n ' t carry out the receive test ; furthermore the model adopt the reverse arithmetic which exert the tree concept in data frame and establish a virtual fountain tree permanently , the proagmme can back - search the virtual fountain tree when it is running . these operation increase the calculate speed and it result in the higher receive efficiency and precision . the thesis design a programme to compare the prediction results based on ray tracing method of virtual fountain tree between the measurement results and prediction results based on the other transmittion models . the comparsion result indicate the new model is a better model
它可应用于任何复杂的传播环境中，能找到发射机到接收机之间的所有电波传播路径而无须冗余的计算，是一种准三维的预测模型；另外，从本质上讲，它仍然是一种基于镜像理论的点对点的射线跟踪法，所以它无须进行接收测试；而且由于采用了反向算法，运用数据结构中多叉树的概念，先确定需要计算的场点位置，找出所有能从源点到达场点的射线，并且可一次性建立一个虚拟源树，以后每次的计算只要通过对该树进行后序遍历即可，大大提高了运算速度，因而有较高的接收效率与精度。本文对该模型进行了相应的仿真，并将其预测结果与实测结果以及基于cost231经验性模型和基于强力射线跟踪确定性模型的预测结果进行了比较，结果表明了该模型的优越性。 - A square sensing area was formed upon each of the saw propagation paths using photoresist . when some kind of material deposits on this area , the saw propagation velocity will decrease due to the mass - loading effect , causing a shift in the device ' s oscillation frequency , which gives indication of the mass deposited . the dual - path architecture , one for sensing and one for reference , was used to compensate for the disturbance of temperature
利用光刻工艺在每个声传播路径上构造了一个方形质量沉积区，当有物质沉积到该区时，由于质量沉积效应，声表面波的波速发生变化，使以延迟线作为反馈回路的振荡器的振荡频率发生变化，并通过这一变化反映出沉积物的质量。 - Because of the digitally rebalanced circuit , the sensor is capable of achieving better static and dynamic characteristic , higher sensitivity and stability . in this paper , the propagation path of light in the step index fiber and graded index fiber is introduced firstly . then the paper sets up the coupled power model and develops the coupling function
在文中，首先介绍了光线在阶跃型光纤和梯度折射型光纤中的传播路径，以及在一端镀有反射膜的1 4波节长度的grin透镜中的成像规律，并推导了光功率耦合函数。 - As a result , the low - frequency contents increase as the centroid of signal spectrum experiences a downshift , in case that frequency is independent on quality factor , the offset of the centroid frequency is proportional to the integral of attenuation factor along wavepath , thus can he used to reconstruct the attenuation distribution
假设介质的品质因子与频率无关，地震波主频的偏移量与吸收系数对传播路径的积分成比例，则通过它们之间的关系可以估测介质的吸收系数。
