feedback amplification 中文意思是什麼
feedback amplification
解釋
反饋放大- feedback : 反饋的信息
- amplification : n. 1. 擴大；擴充。2. 【電學】增幅，放大（率）。3. （聲明等的）補充材料。
-
The maximum gain - before - feedback is the most amplification of the sound before the sound system goes into feedback and starts squealing
最大反饋前增益，就是音箱開始嘯叫，或者出現振鈴效應時候的增益。 -
When this feedback current arrives, it increases the voltage further, which in turn recruits more feedback current and causes additional amplification
返回的回饋電流會讓電壓升得更高，因此又會使回饋電流變得更大，造成更大的放大作用。 -
The u. c. l. a. researchers matched the scattered light with the pump energy from another laser in a way that created constructive feedback, resulting in a net amplification of light
加大洛杉磯分校研究人員讓散射光與來自另一具雷射的能量相遇，以產生建設性的反饋，藉此放大光的凈振幅。 -

This paper analyses the type, function and characteristics of usual proportional control valves and raises a new modificative version in the light of their drawback. that is, basing on the principle of flow amplification and electrical feedback and throughout calculation and analysis on flow closed loop control and pressure flow combination., determination of the minimum controlled pressure difference as well as flow controlling range and structure of main valve and research of the dynamic and static characteristic, the paper puts forward control principle of " flow - load pressure change - displacement revision " and pressure / flow double closed loop, and further expounds that using a proportional controller and a electric mechanical transducer can separately serve the control function of pressure or flow as well as flow pressure combination
本論文分析了目前常用比例閥的類型、功能、特性，並針對其不足提出新的改進方案，即：以流量放大，電反饋兩個原理為基礎，通過對流量閉環控制及壓力流量復合的計算分析、確定上最小控制壓差及流量控制范圍，確定主閥結構、功能特性研究等，提出了「流量? ?負載壓力變化? ?位移修正」的控制原理和壓力流量雙閉環控制原理，並進一步論述了利用一個比例控制器和一個「電?機械轉換器」就可完成獨立的壓力或流量控制功能以及流量壓力復合控制功能。
