Surface transverse wave has the 1 . 6 high frequency than rayleigh type surface acoustic wave ( using the same technology the frequency of devices of stw has about 1 . 6 high frequency than rayleigh type surface acoustic wave ) . the paper introduces the theory , design parament , technology and result expeiment of surface acoustic wave ( includes rayleigh surface acoustic wave and surface transverse wave , simple stw ) with low insertion loss , high q and researches the high frequency , low phase noise oscillator with 1ghz stw resonator as frequency element . and describes measurement method and finally experimantal result of the low phase noise surface acoustic wave oscillator 本文研究了以低損耗、高q值聲表面波(其中包括聲表面瑞利波- - rayleighsurfaceacousticwave ,和聲表面橫波等)諧振器的工作原理、設計參數、制作工藝及其實驗結果,并且研究了以1ghzstw諧振器為頻控元件的高頻率、低相位噪聲聲表面波振蕩器,以及低相位噪聲聲表面波振蕩器的測試方法和最終的測試結果。
The study object of this paper is design and study of the syetem - mentioned above . the circumstance paraments of remote communication room such as temprarure , humidity , fire alarm and air - condition ' s on - off could be real - time supervised . this paper firstly intrduces the backgroud and study signification of the task , review the development of supervisement system and narrate the frame , technology criterion , network frame and calculation mode of variet kinds supervisment system . the network functions of variet kinds of confignation software are analysed 本文以西昌衛星發射中心遠程機房監控系統的研究設計為對象，通過網絡實現對遠端的14個通信機房實時監控，實時監測室內溫度、濕度、實時監測室內煙、火，實時監測空調設備運行情況，出現異常情況，聯動告警裝置，本端機房和遠端監控機房自動聲光告警。
Modbus transducer is the key device in the system and is used to offer power supply of pressure and temperature sensor , to collect signal , to linearizate and compensate temperature , to calculate density , volume and mass , to transmit data to modbus network , and display the data . so the modbus transducer is a multi - parament measurement , intelligent control device which can manage multi - signal 變送器是系統的核心設備，其作用是為油罐溫度、壓力、液位、可燃氣濃度等傳感器供電，采集傳感器信號并進行線性化、溫度補償等處理，完成密度、體積和質量等參數計算，將數據輸出到modbus現場總線測控網絡，根據需要現場顯示計測量參數。
Bias voltage , which are related to the superlattice structural paraments , the doped densities and the applied bias voltage . we have also investigated the characteristics of superlattice under hydrostatic pressure by simulations 超晶格的負微分電導區還導致出現固定偏壓下隨時間變化的電流自維持振蕩，振蕩產生的條件依賴于其結構參數，摻雜濃度和外加偏壓的大小。
The paper also deal with the type rta52l diesel engine main paraments choosing principle , technical guideline requirements and major struction specility in design 本文還闡述了該型船用柴油機的主要參數的選擇原則，該型柴油機的設計技術性能指標要求和主要結構設計特點。
The necessary data are used to adjust the parament used in the numerical simulation 而且為數值模擬的參數選擇提供了必要的現場資料。
