The results of exitensive transmission experiments of the Red-leaf virus on millet revealed that it was neither seed nor mechanically transmissible.In addition to Aphis maidis Fitch. Macrosiphum granarium Kirby and Toxoptera graminum Rond, 13 additional aphids, namely Acyrthosiphum pisum Kaltenbach, Aphis glycines Matsumura, Aphis gossypii Glover, Aphis medicagini Koch, Aphis sacchari Zehntner, Cavariella salicicola Matsumura, Hyalopterus arunidis (Fabricius), Myzus momonis Matsumura, Macrosiphum sp., Perphyllus sp. & two un-determinated sp. have been proved to be the vectors of the Milled Red-leaf virus. The efficiency of the disease transmission of several of these aphids was arranged in regressive order as follows Aphis maidis 100%; Aphis sp. (from Prunus trilola Linde) 50%; Hyalopter arunidis (from Prunus persicae) 40%; Aphis medicagini (from Vicia fabae) 40%; Myzus momonis (from Prunus persicae) 30; Aphis sacchari (from Holcus sorghum) 20%; Toxoptera graminum 20% & Macrosiphum granarium 10%. The efficiency of these aphids in transmitting the virus was largely influenced by the kind of plants on which they had fed for aquisiting the virus.Experiment conducted in large screen cages indicated that it was the winged corn aphis which mainly responsible for the destination of the disease. These evidences have been confirmed by fields observations, and the non-winged aphids were rather inactive.

比較大規模的传病試驗的結果証知小米红叶病病毒不借种子传播,很难或者不能用机械式方法传染。除玉米蚜、麦长管蚜和麦二岔蚜以外,在人工传病試驗中,試用豌豆无网长管蚜、大豆蚜、棉蚜、苜蓿蚜、甘蔗蚜、桃大尾蚜、桃蚜、桃拟瘿蚜、Cavariella salicicola Matsumura和四种未定名的蚜虫中有一些蚜虫能传染小米紅叶病病毒,它們的传病力以病株百分率核計为玉米蚜100%;榆叶梅上的一种未定名的蚜虫50%;桃大尾蚜40%;苜蓿蚜40%:桃拟瘿蚜30%;甘蔗蚜20%;麦二岔蚜20%和麦长管蚜10%。蚜虫的食性决定蚜虫的传病效能,一般的情况是发生在小米上的玉米蚜,把红叶病传染給小米的效能比传染給小麦的較高,相反的,发生在小麦上的麦二岔蚜,把病毒传染給小麦的能力比传染給小米的較高。但同时飼育蚜虫的寄主种类也影响蚜虫的传病率。凡是在小米上面吃食的蚜虫传病給小米和小麦,都比在小麦上面吃食的蚜虫,接种植株发病的百分率均較高。籠罩試驗表明小米紅叶病主要的借有翅玉米蚜传播,无翅蚜的传播效能不大。在田間作观察以及根据药剂噴射試驗均証明这个事实。

This experiment has shown that the electronic beam in the used gun could be further contracted and the "screen-current" could thus be increased by 40% by me ans of a pre-focussing arrangement. Hence the cathode could be worked at a lower temperature correspondingly and its life could be prolonged; and the improvemeent of the resolution of the "large-screen image projector" could also be benefited.

The influences of various factors of dielectric target in certain pick-up tubes, storage devices and electro-optic display devices on the resolution are studied in this paper. By considering the general case of anisotropic dielectric target, the optical transfer function (OTF) from surface charge raster pattern to potential or optical pattern of dielectric target is deduced. The resolution limit of the dielectric target is analyzed quantitatively. The leakage of electricity on surface and the influence of the other medium film layer introduced on target surface on the resolution are discussed in detail. For example, the MTF curves of silicon target in pick-up tubes, polystyrene target in video tape and anisotropic medium target of DKDP crystal in large screen projection TV are calculated by TQ-16 type computer, then the resolutions of these targets are found accordingly. The results obtained well coincide with the experimental curves and data in literatures. Finally, the calculation results are further confirmed by experiments on DKDP crvstal.

本文研究了在某些摄象器件、存贮器件或电光显示器件中介质靶诸因素对分辨率的影响。在考虑各向异性介质靶的普遍情况下,推导了由表面电荷光栅图象到电位图象或光象的介质靶的光学传递函数。定量地分析了它的分辨率极限;较详细地讨论了表面漏电和靶而其他介质膜层的引入对分辨率的影响。作为例子,利用TQ-16型计算机计算了摄象管中的硅靶、录象磁带中的聚苯乙烯靶和大屏幕投影电视中的DKDP晶体各向异性介质靶的MTF曲线,从而求得了它们的分辨率,所得结果与国外资料报道的实验曲线和数据很好地吻合。最后,用DKDP晶体所做的实验进一步证实了计算的结果。
