The results show that there exist the fast P wave (qP1), fast S wave (qS1), slow S wave(qS2) and slow P wave(qP2) in 3-D dual-phase anisotropic media during the propagation of elastic wave. And the special phenomena such as the S wave splitting, the blind paints of the S wave splitting and wavefront triplication are clearly observed.

结果表明，弹性波在三维双相各向异性介质中传播时存在快纵波qP1、快横波qS1、慢横波qS2和慢纵波qP2，并清楚地观测到了横波分裂、横波分裂盲点、波面三分叉等特殊现象。

In order to clear the aphid and Citrus tristeza disease epidemiology, in this research, to determine the dominant stocks of aphid on citrus by investgatting the occurrence and the damage of the aphids; to clear the relation of aphids and citrus tristeza disease epidemic by analysissing the identity and the efficiency of T.

为了解蚜虫与CTV流行的关系，本试验通过调查柑桔蚜虫的发生与为害，明确柑桔蚜虫的优势种群；就橘蚜传播柑桔衰退病的传毒特性、传毒率、影响传毒率因素等的分析，明确蚜虫在柑桔衰退病流行中的作用；以及对带毒橘蚜体内的CTV分子生物学检测。

The fluctuating deviation of bed voidage and theenhancement index of bed uniformity derived in this study can describerespectively the bed uniformity and its extent. A new criterion of demarcationof uniformity, composed of materialparameter, operating parameters (H0, u/umf) and vibrationparameters, can be used to predicting a suitable range ofbed uniformity.

对空隙率波动偏差的分析表明，振动参数、颗粒物性和操作参数均对床层均匀流化行为有不同程度的影响，且振幅和振动频率越大越能明显提高以小米或玻璃珠为物料的床层的均匀稳定性，而颗粒物性和操作参数直接影响振动能量在床层中的传播。

The basic concept of the proposed scheme is to find the union sets of the output ports of switches in the paths between the source processing node and each destination processing node in the multicast group.
