From the disser tation , it is noted that smart antenna can effectively deal with mobile communication signals such as coherent signals , non - gaussian signals and multipath signals , etc 通过本文的研究，实现了智能天线对接近现实的相干信号源、非高斯信号源、经多径信道传输后等情况下信号的有效处理。
Launched in october 2004 , the satellite was broadcast on a trial basis from january 2005 . it went into operation last month . the fy - 2c satellite is located some 36 , 000 kilometres above the equator at 105 Fy - 2c卫星是一颗由中国国家气象局操作的地球同步气象卫星，二四年十月发射升空，二五年一月开始实验性广播，经多月的测试后于六月投入运作。
And the rusted coating and the long acting heavy corrosion protection are hard to achieve at the same time . to this kind of situation , for many years , we successfully developed the th - 98 heavy anticorrosion painting for ultralow surface treatment 针对这种情况，我们组织多年，研究成功地开发了th - 98系列超低表面处理型重防腐涂料，经多家用户试用认为有以下几大优点：
Through the determination of the wood property for making the pulp and paper of seventeen choiceness clones in masson pine seed orchard , and through the comprehensive judgement on several characters , the author selected ten optimal choiceness clones for the pulp and paper production industry material forest 摘要对马尾松种子园17个优良无性系进行制浆造纸性能的测定，经多性状综合评判分析，共选出可供制浆造纸工业原料林造林的最佳无性系10个。
As backwash is the key of renewing and keeping up the function of filter , so some factor optimization experiments of backwash have been done . the optimum operating parameters of air scour and water backwash of ceramics media are chosen by multiple factors experiments : qa = 15 l / s ? m2 , qw = 5 l / s ? m2 , t1 = 1min , t2 = 5min , t3 = 5min 经多组实验正交分析结果后得出了涂铁陶粒滤池反冲洗实验的最佳参数组合：气冲强度15l / s ? m2 ，水洗强度5l / s ? m2 ，单气预冲1min ，气水同时反冲洗5min ，单水漂洗5min 。
Especially point out : product this adopt new invention leather simulation oil fill a prescription , because oil , so as such alkaline wounded leather sanitizer as all - round ink , etc . its clean strength , need brushing lightly several times with the soft brush after spraying a product , and then retrieve the dirt with the clean soft cloth 专除真皮污垢，采用新发明皮模拟油配方，清洁效果好，清洁后皮革光亮、滑爽、柔软，乳白膏（液）体，原味无味(经多道新发明技术处理，卫生、环保） ，不含伤皮清洁剂，不伤皮肤、皮具，也可用于其它材质家具表面(木、石等材质家具擦一点就灿烂) ，并具有美容、保养、上光、防霉、防水与抗污等多功能的集合，令皮具光洁柔软如新。
The carbonate reservoir rock includes many influence factors that it is through many phases structure bursts and the ancient karst to act on jointly the formation and with which the rock karst gives first place . the complicated oil field of karst cave and crack are controlled by limestone reservoir and the crevices - cave system , which have many characteristics such as vivid and great in style , irregular distribution , the limestone cave in crack and unhomogeneity of rock etc . these kinds of reservoir belong to a world difficult and extreme problem on valuation and cognition 它是经多期构造破裂与古风化岩溶共同作用形成的、以灰岩岩溶为主控因素、以储集体控藏和缝洞系统控藏为主的溶洞?裂缝型复杂油气藏，表现为其不规则形态和不均匀分布、裂缝溶洞发育不均一、储层非均质性极强等特点，认识和评价该类储层属世界性难题。
This paper selects those elements which have significant effect on diseases by statistical analysis in yinchuan area and set up ann model for the incidence of the diseases by putting those elements into many - level bp arithmetic of feed - forward backprop neural network as input varieties to study for training . and comparing the outcome of it with that of statistical model 本文通过统计分析，选取影响银川地区疾病发病率的主要气象因素，将其作为输入变量经多层前馈型神经网络的bp算法进行学习训练，建立了疾病发病率的人工神经网络( ann )预报模型，并将其预报效果与统计方法模型预报效果进行比较。
