1073	实验结果表明，与现有基于加权关联规则挖掘的跨语言扩展算法比较，本文扩展算法能有效遏制查询主题漂移和词不匹配问题，可用于各种语言的信息检索以改善检索性能，	A comparison between the proposed expansion algorithm and the existing CLQE algo-rithms based on weighted association rules mining is made, which shows that the former can effectively restrain the problems of query topic drift and word mismatch, and can be used in information retrieval in various languages to improve retrieval performance.
1074	扩展模型中后件扩展获得最优检索性能，混合扩展的检索性能不如后件扩展和前件扩展，	The RCE achieves the optimal retrieval performance in the proposed expansion models, and the retrieval per-formance of the RACHE is not as good as that of the RAE and the RCE.
1075	支持度对后件扩展更有效，置信度更有利于提升前件扩展和混合扩展的检索性能。	The support is more effective for the RCE algo-rithm. The confidence can make the RAE and the RACHE get the best retrieval result.

1077	近年来，Ku 和 Ka 卫星在广播、通信和军事等领域应用数量越来越多，传统的 Ku 和 Ka 波段星地链路降水衰减预报模型基于经验关系和理想假设，考虑降水微物理特性不足，	In recent years, the number of satellites with Ku and Ka band has been increasing in the fields of broadcast-ing, communication and military. However, traditional prediction models of rain attenuation for earth-space links in Ku andKa band are based on empirical relationships and ideal assumptions, which consider insufficient precipitation microphysical properties.
1078	针对此问题，在实测降水粒子微物理特征的基础上定量分析了降水垂直分布、粒子形状、粒子取向、粒子相态等对 Ku 和 Ka 频段信号衰减的影响特性。	Aiming at this problem, the effect of vertical distribution of precipitation, particle shape, particle orientation andphase on signal attenuation are quantitatively analyzed based on measured rainfall data.
1079	结果表明，与考虑降水非均匀垂直分布的计算结果相比，ITU 和 SAM 模型是基于降水分布均匀的假设，无法代表降水垂直分布不均匀时的衰减情况;	The results show that compared with the calculation results of nonuniform vertical structure of rainfall, ITU and SAM models are based on uniform precipitation distribution, which cannot represent the attenuation when the vertical rainfall is nonuniform.
1080	降水粒子形状和取向对衰减的影响较小，在 13GHz 和 32GHz 频段，球形和非球形粒子衰减值的平均绝对偏差均在 0.01dB 以下，不同粒子取向时衰减系数的平均绝对偏差最大值为 0.00098dB/km 和 0.0207dB/km;	The particle shape and orienta-tion affect the attenuation for a slight degree, the mean absolute error of attenuation from spherical and non-spherical rain-drops are below 0. 01dB at 13 GHz and 32 GHz, and the maximum mean absolute error of specific attenuation for differentparticle orientations is 0. 00098dB /km and 0. 0207dB /km.
1081	不同相态的降水引起的衰减差异较大，衰减值从大到小依次是湿雪、水和冰。	There are different attenuation caused by precipitation with differ-ent phases, the values in descending order is wetsnow, water and ice.
1082	研究结果可以为 Ku 和 Ka 波段星地链路传播特性评估及降雨反演新方法提供基本的理论支撑和数据参考。	These results will provide basic theoretical support anddata reference for evaluation of propagation characteristics and estimation of rainfall by earth-space links at Ku and Ka band.
