This paper outlines a new method of amplitude shading. It can be applied to any type of arrays. Directivity pattern obtained by this method is the optimum or nearly the optimum in the sense that for specified sidelobe level the area enveloped by sound pressure square in the considered plane is a minimum, or directivity factor a maximum. This method is applied to the are array with cylindrical hollow baffle. Directivity patterns obtained by this method is compared with those obtained by several other methods,...

This method is applied to the are array with cylindrical hollow baffle. Directivity patterns obtained by this method is compared with those obtained by several other methods, these results show that performance of the array shaded by this method is the optimum.

本文给出了一种幅度束控方法,它适用于任意类型的基阵.在指定旁瓣级时,它可以得到最佳的或接近最佳的指向性图案,这里最佳的含义是,声压平方这个函数在所研究平面围成的面积达到最小,或者指向性因子达到最大.本方法可以改变各旁瓣和零点的位置,改变各旁瓣的相对高度,因此可以在其它各种意义上获得希望的指向性函数. 本文使用这种方法对具有圆柱型反声障板的补偿圆弧阵进行了综合,并与其它几种方法进行了比较.该方法还被用于线阵,它可以得到与契比雪夫—道尔夫束控方法完全相同的束控系数和指向性函数.

Based on the centrifugal spray nozzles and the charaterization of outflow under higher water pressure, this paper theoretically analysed the two continuous processes of the atomization mechanism of swirling flow water (e.t. the processes of the hollow conical film formation and that the film callapses into droplets). By analysis, this paper recognized that the former primarily related to the manner of the water motion within a spray nozzle, and the latter, the aerodynamical stability of the space medium...

Based on the centrifugal spray nozzles and the charaterization of outflow under higher water pressure, this paper theoretically analysed the two continuous processes of the atomization mechanism of swirling flow water (e.t. the processes of the hollow conical film formation and that the film callapses into droplets). By analysis, this paper recognized that the former primarily related to the manner of the water motion within a spray nozzle, and the latter, the aerodynamical stability of the space medium (air) in which water is spraied. Based on aforementioned the writer presented the calculating method of evaluating spray nozzle energy.

本文以离心喷咀为对象,以较高水压作用下的出流特征为基础,从理论上分析了喷旋水流离散机理的两个连续过程,即空心锥膜形成过程和锥膜破碎成滴过程.通过分析明确了前者主要与水在喷咀内部的流动情况有关,后者主要与水喷入空间介质(空气)的动力稳定性有关,并由此提出了喷咀能量评价的计算方法.

本文中简单叙述了KYF-450型离子镀设备。用HCD工艺完成了反应离子镀氮化钛。膜层的硬度在2000kg/mm~2以上,沉积速率是0.08μ-0.23μ/分。沉积速率是坩埚与基体间距和基体负电位的函数。膜层的硬度是基体负电位和氮气分压的函数。氮化钛膜的颜色随氮气分压的变化而改变。测定了氮化钛膜的光谱反射率。
