【正文】 is presented and the advantages of Lossy works are discussed. Examples of twostage Amplifiers using PETs and bipolar transistors are Presented to show the feasibility of this particular work in low power Amplifier designs. 寬頻帶放大器輸出網(wǎng)絡設計 本文介紹了有損增益補償網(wǎng)絡的一分析性設計方法，并討論了有損網(wǎng)絡的優(yōu)越性。所達到的效率高于 40%，溫度達到 300℃ 。 Engineering Development Studies for Integrated Evacuated CPC Array: Interim Technical Progress Report Abstract: An improvement in optical efficiency over contemporary external reflector evacuated tube collectors was achieved by integrating the reflectors surface into the outer glass envelope. The design, fabrication and testing results are described for a prototype collector based on this concept. Efficiencies above 40% up to 300℃ are achieved. A prehensive testing program to measure performance and operational characteristics of a 2m2 panel (45 tubes) is being carried out. 通過把反射器表面與外玻璃封殼相結合，實現(xiàn)了目前的外部反射器抽空管集熱器 光效率的改善。它可以基本上屬于其中一種體裁，而在某種程度上兼有另一種體裁的特征。摘要主要可分為 指示型、信息 指示型和信息型 3種。進而給出適用于大客車 AMT離合器的最佳接合規(guī)律。 Management and application of process planning resource database in CAPP Abstract: A structure of an integrated CAPP system is presented. The functional model of process planning resource management in CAPP is built up, and the integrated data management of process resource database and its application in CAPP are achieved. CAPP中工藝資源數(shù)據(jù)庫的管理與應用 提出一個集成化 CAPP系統(tǒng)的總體結構，建立 CAPP中工藝資源管理模塊的功能模型，實現(xiàn)工藝資源數(shù)據(jù)庫在 CAPP中的集成管理和應用。指示型摘要一般不介紹方法、結果、結論的具體內容，不包含任何數(shù)據(jù)。
