Deduction shows that a series inductor can be applied as the inter - stage matching network between the two stages 围绕级间匹配网络的实现这一核心问题，推导出级间匹配电路可以用一个串联电感实现。
After the analysis , we think the reason is that interstage matching between second stage and third stage , output matchin 经过分析认为是因为大信号下第二级与第三级级间匹配、第三级输出匹配不是十分良好。
A hierarchical control architecture is adopted , which comprises of a microprocessor level and a pc level and communicates through blue - tooth between two levels 采用了微控制器和pc机两级控制体系，两级间采用蓝牙通讯。
In this paper , the traditional cascode structure of cmos lna is considered as a two - stage amplifier and inter - stage matching network is introduced accordingly 本文也对cmos低噪声放大器进行了分析，将传统共源共栅结构看作二级放大器级联形式，并由此引入级间匹配网络。
The development of pq valve has been introduced in detail as well . by studying structural principle of byl pq valve , its work principle is introduced in chapter 2 第二章通过对pq阀内部结构原理、液压半桥控制原理、级间反馈等原理的分析，阐明了pq阀系统的工作原理。
In the forth chapter the series negative feedback and interstage mismatching are presentation , and a low noise amplifier whose operating frequency is 1 . 5ghz 1 . 8ghz is developed 第四章详细介绍了源极串联负反馈和级间失配法,并设计和制作了1 . 5ghz 1 . 8ghz低噪声放大器。
The negative correlation of the dry matter production to the age class of rhizome indicates level of significance ( p < 0 . 05 , po . ol ) in leymus chinensis , calamagrostis epigeios and c . rigidula populations 羊草、牛鞭草和硬拂子茅种群根茎的干物质积累量与龄级间的负相关关系达到显著和极显著水平。
From the viewpoint of equilibrium thermodynamics , this dissertation establishes the stepless - cooling mathematic model , and investigates the corresponding orderliness and characteristics of the stepless - cooling gas turbine cycle 本文建立相应压气机入口注水无级间冷模型，从理论上分析研究无级间冷燃气轮机循环的机理和特性。
