A method based upon simple diffraction theory is described for the calculation of modified paraboloid reflectors to produce from a point source a shaped beam of arbitrary shape in one plane and uniformly narrow in the perpendicular planes. A specific application of the shaped beam antennas is in connection with radar antennas designed for height finding. In this case the antenna must have a sharp elevation beam for obtaining precise elevation information and a rapid elevation scan. The beam must be relatively...

A method based upon simple diffraction theory is described for the calculation of modified paraboloid reflectors to produce from a point source a shaped beam of arbitrary shape in one plane and uniformly narrow in the perpendicular planes. A specific application of the shaped beam antennas is in connection with radar antennas designed for height finding. In this case the antenna must have a sharp elevation beam for obtaining precise elevation information and a rapid elevation scan. The beam must be relatively broad in azimuth in order that the target will be held in the beam long enough to obtain height information. If a fixed minimum of illumination is to be achieved at a given linear distance on both sides of the center line of the azimuth beam, the amplitude pattern must have the so-called "double cosecant" or "beavertail" shape.

本论文讨论如何利用简单衍射理论,计算改良抛物面反射器天线幅射之图型。此反射器可将一无方向性辐射源之能量聚集于任何形状之波束中。此原理可以应用在地面上或船面上寻求飞机高度雷达天线之设计。在此类雷达中,天线之方位图型必须为“双馀割平方”式;其特性为自波束对称轴线起,至其两端,辐射一次路程之功率,与方位角之馀割平方成正比。得此图型之最简易方法为置一狭窄之铅垂金属条于一截形抛物面反射器之中心,金属条之宽度,可改变波束之方向性;其支距,即金属条与反射器之距离,可影响两反射波之位相。故改变金属条之宽度及其支距,可得欲得之图型。 利用衍射及干涉理论,计算金属条及截形抛物面所生之总图型为:在方位面内,幅射强度J_H与水平角θ之关系为: J_H =AA[sin~2(15πsinθ)/(15πsinθ)~2-2(1-cosπ/4)sin(2πsinθ)/2πsinθ(sin(2πsinθ)/2πsinθ-sin(15πsinθ)/15πsinθ)]A为辐射波振幅,A为A之复共轭数。计算之结果与实验之结果,颇为一致。

This paper incends to give a comprehensive survey of the high encrgy nuckar interactions produced in emulsions and cloud chambers by particles of an energy in the range 10~21 to l014 cV. The more difficult problems of measurement, such as determination of the primary energy, identification of the secondary particles and estimation of the target mass, are first brought up for discussion. Effort has been made to explain whenever possible the physical meaning of the quantities, which may give information concerning the collision mechanism and hence the internal structure of the colliding particles. The main quantities or these arc the angular distribution, the transverse momentum and the inelasticity, in addition to the multiplicities of the different kinds of the secondary particles. For these quantities, the principle of measurement, the accuracy of experiment and the meaning of the results, particularly the latter, have been emphazised and discussed in some detail. Finally, the various models of the "one emitting centre" and of the "two emitting centres" arc discussed entirely from the physical point of view and are compared with the experimental results. It is hoped that this paper may present a general picture of the recent development of the high energy nuclear interactions and indicate the problems siill remained to be sclved.

这篇总结性文章叙论了由能量高到10~(11)—10~(14)电子伏的粒子在乳胶和云室中所引起的高能核作用。文中首先提出和讨论了在测量上较困难的一些问题,例如,初能量的测量,次粒子的辨认和靶质量的估计。一些可能揭示碰撞机构从而显示核子内部结构的物理量的物理意义,也适当地加以讨论和阐明。除了不同次粒子的多重性外,主要的物理量是:次粒子的角分布、它们的横动量和非弹性系数。关于这些量的测量原理,实验准确度和实验结果的物理意义,特别是后面一点,都有了较充分的检查和讨论。末了,“一个发射中心”和两个发射中心”的各种模型也从物理观点作了较定性的描述和讨论,并和实验结果作了比较。希望通过这篇文章对高能核作用目前发展的概况、尚存在的问题及今后工作的方向能有一定的了解。

Nuclear interactions induced by cosmic ray high energy particles have been studied by means of a multiplate cloud chamber at 3185 meters above sea level with liquid scintillator as target material. From the analysis of 18 interactions induced by charged primaries it is found: (i) average primary energy E0=41±8Bev (by Castagnoli formula), (ii) average multiplicity of charged secondaries ns =4.9 ±0.3, (iii) with

利用放置在海拔3185米处的多板云室,以液体闪烁体作靶,研究宇宙线高能粒子产生的核相互作用。本文分析了18个由荷电粒子引起的核作用事例,用Castagnoli公式求得初能平均值_0=(41±8)Bev,荷电粒子平均多重性_s=4.9±0.3,以x =lgγ_ctgθ_ι为变量作次级粒子的角分布,发现dN/dx分布可能存在着两个峯,文中试用二心模型对此角分布进行了讨论。
