Improvement in the synthesis method of the Pierce electron gun;
对皮尔斯电子枪综合法的改进
Artificial neural network(ANN) has been successfully used in the design of Pierce electron gun.
基于人工神经网络(ANN)的皮尔斯电子枪初值设计方法,不但能有机地结合迭代综合法与非迭代综合法的优点,还能把前人体现在实验数据中的设计经验通过训练样本融入到其中,从而设计出很接近实验值的新电子枪。
In order to get over this defect,we use EGUN,ORION and MAGIC to simulate 24 Pierce electron guns of similar structure whose control and anode electrode are bulletheaded.
用软件仿真不同结构的电子枪时发现其结果的误差百分比较大,不易把握其误差规律,为了克服此缺点,本文用EGUN,ORION和MAGIC分别对24支结构相似(控制极和阳极均是圆头形)的皮尔斯电子枪进行了仿真,并将软件计算值与相应的实验值列表比较表明:①用EGUN与ORION这两种同类型软件仿真结构相似的电子枪时,它们的精度虽然也不同,但误差范围变化较小;②大型通用的电磁场分析软件MAGIC计算电子枪的结果虽然比专业的电子光学软件EGUN,ORION逊色,但有规律可循:导流系数普遍偏低约10%,注腰半径的精度较高,注腰位置基本准确。
The importance of the loaded Q are analyzed on the basis of phase noise equation of Leeson model in feedback oscillator,the formula of loaded Q is derived by the analysis of Pierce oscillator circuit,and we can draw a conclusion that the larger C1 is,the higher loaded Q becomes.
从反馈振荡器的Leeson模型相位噪声表达式出发,分析了有载Q的重要性,针对基本皮尔斯振荡电路推导出有载Q的表达式,得到C1越大,有载Q越高的结论。

A Comparison on the Semiotic Theories of Peirce and Saussure;
皮尔斯与索绪尔符号观比较
Peirce s semiotic theory con- sists of three inseparable parts:representamen,object,and interpretant,which throws wholly new Peircean light upon the analysis that loan words are regarded as repre- sentamens,the things they represent as objects,and the nations that interpret them as interpretants.
