  1. Static and dynamic trial experiments indicate that the system, not only can well simulate the prime governor and self _ equilibrium characteristics of a prime mover with its simple hardware line, small size and versatility, but also can highly improve the whole system ' s control precision, reliability and stability when compared with the system design of the analogy circuits

    靜態、動態測試實驗表明：該控制系統，不僅硬體線路大為簡化、體積小、通用性強，能夠很好地實現對原型調速器及原動機自平衡特性的模擬，而且與模擬電路的設計方案相比，整個系統的控制精度、可靠性和穩定性等大幅度提高，具有明顯的優勢。
  2. Secondly the detection precision is only related to the synchronization phase but not to the amplitude of the mainline voltage because that it uses the optimized pulses synchronous with the mainline voltage as modulation signals. thirdly it decreases the requirement of the input low pass filter and eliminates the error resulting from the direct component and even harmonics of load current. the most significant merit is that it can eliminate the effect of a few low order odd harmonics and the detecting circuit is easy to be implemented

    模擬和實驗結果表明該方法的主要優點有：不需使用乘法器進行信號調制，調制信號採用與電網電壓同步的優化特定脈沖，其檢測精度只與同步相位有關，而與電網電壓幅值無關；降低了對輸入低通濾波器的通頻帶要求，直流和偶次諧波分量對檢測精度沒有影響；突出的優點是可以消除有限個低奇次諧波對檢測結果的影響。
  3. We give ptr ' s amplitude and phase signal of one dimension based on the theory of ptr, discuss the ptr ' s signal ' s frequency characteristic, and a method for measuring thermal diffusivity of opaque materials is introduced. then, we study on anisotropic materials " thermal conductivity, the temperature field and thermal conductivity tensor of anisotropic materials is theoretically deduced from the theory of ptr, and is proved by the experiment

    從光熱輻射理論出發，推導出一維情況下ptr信號的振幅和位相表達式，討論了光熱信號的頻率特性，介紹了一種用ptr技術測量不透明材料熱擴散系數的優化方法；接著研究分析了各向異性介質受調制激光束輻照下產生的光熱信號，在理論上推導出各向異性介質的溫度場以及熱導率張量並給予一定的實驗驗證。
  4. Theoretical analysis and simulation results demonstrate that asymmetries in lower and upper sidebands and imd magnitude variation depending on envelope frequency and junction temperature can appear, these results are in accordance with measurement results, and show that electrical and thermal memory effects exist

    理論分析和模擬結果表明功率放大器上下邊帶不平衡和互調失真幅度依賴于包絡頻率和結溫，結果和測量的結果是一致的，說明存在電和熱記憶效應。
  5. After using three methods of estimating equilibrium of money supply, we can draw these conclusions : ( 1 ) the money gap presented business cycle character from 1978 to 2004. ( 2 ) from 1994, the fluctuated extent of money gap decreased, which means the efficiency of monetary policy raised steadily. ( 3 ) the money gap has the forecast function of extreme in business cycle

    本文採用均衡產出決定法、周期趨勢消除法和貨幣供給增長率推演算法分別測算1978 - 2004年我國的貨幣缺口，結果表明： （ 1 ）在過去的27年中，貨幣缺口變化呈現出周期性特徵； （ 2 ） 1994年以後貨幣缺口的波動幅度變窄，表明貨幣政策調控的效果逐步提高； （ 3 ）貨幣缺口對經濟周期的峰值具有預警功能。
