接收测试 meaning in English
acceptance testing
Examples
- User acceptance test
用户接收测试 - Besides in nature , it is ray tracing based on the method mirror image . so it need not receive test , have higher computational efficiency and assure higher precision
另外,从本质上讲,它是一种基于镜像理论的点对点的射线跟踪法,所以无须进行接收测试,因此有较高的计算效率,并且保证了较高的精度。 - Relative performance parameters of some transport equipment , satellite signal and solar signal in a station for verifying the feasibility of selective scheme are tested
在选定方案的基础上对相关设备的性能进行了测试，并针对设备测试与对卫星信号的现场实际相关接收测试结果进行分析，验证了拟定方案的可行性。 - Dvb - t ( digital video broadcasting ) specification is one of the dttb standards . it has better results in digital television program terrestrial reception test and has good appraisement in digital television broadcasting industry
Dvb - t ( digitalvideobroadcasting )是目前国际认可的数字电视地面广播标准之一，也是广播电视业及多国数字地面电视接收测试中评价最高的地面电视广播标准。 - 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。
