圆锥形

The driving system of the speaker is constructed by a circular PZT bimorph,which is clamped on its boundary,An elastical coupling element is utilized between the bimorph and the speaker cone.

扬声器的驱动元件是边缘固定的圆形PZT 双型弯曲振子，振动——辐射元件是圆锥形纸盆，这两部分之间采用弹性耦合。

The conical-shaped pine trees were the main reasons why I took this picture. Do they look like they were done by a giant with a huge pair of scissors?

这个圆锥形的松树是我拍此照的主要原因，它们看起来像不像是巨人用大剪刀修剪而成的？

本文在前人工作的基础上，基于圆锥形陶瓷盒形输出窗模型，采用Ansoft HFSS三维计算软件的优化模拟，对该输出窗模型的驻波频率特性与各种结构参量的关系进行了优化模拟，分析了该输出窗片结构变化对其表面的电场分布，功率流分布、热量分布的影响，得出最优模型参数。

In this paper, based on a pill-box window model with a conical-shaped alumina ceramic and Ansoft HFSS software, the relation of VSWR with various electrical parameters in the window is simulated; the effects of variations of the output window structure on electrical field intensity, microwave power flow and quantity of heat are analyzed; the electrical characteristics of frequency bandwidth, power capability and heat dissipation for the pill-box window with conical-shaped or disk alumina ceramic are discussed, which shows that, with a rational structure of the window with conical-shaped alumina ceramic, the output capability of microwave peak and average power may greatly be increased, the secondary electron emission may effectively be suppressed, and heat dissipation may become more uniform and be easier for cooling.

The addition of conic funnet (这里的funnet疑似funnel——译者注)can partially improve the situation, but such horn antennas have uneven diagrams in vertical and horizontal planes, which is very undesirable for antennas that pretend to be good and efficient feed for dish.

加上圆锥形漏斗可以部分改善这一状况，但是这样的喇叭天线的水平和垂直方向图是不平衡的，这对于一个很好的，高效的抛物面馈源来说是个很大的麻烦。

The garden, which was slightly arched, had in its centre, on the summit of a hillock, a fine pointed and conical fir-tree, whence ran, as from the peaked boss of a shield, four grand alleys, and, ranged by twos in between the branchings of these, eight small ones, so that, if the enclosure had been circular, the geometrical plan of the alleys would have resembled a cross superposed on a wheel.

园里的地面是微微隆起的，中间有个稍高部分，一株美丽的圆锥形的枞树耸立在那上面，宛如圆盾中心的突刺，四条宽道从那中心出发，伸向四方，每一条宽道又都有两条小路，各向左右分展出去，各各相通，因此那片园地，假使是圆的话，那些道路所构成的几何图形就象一个加在轮子上面的十字架。
