So this paper tries to solve these problems through the following work : first, we select some index to valuate the close - end funds, including income, stability, risk in falling, stocks selecting ability and tuning ability, based on overseas funds valuation methods and domestic market condition ; second, we analyze the stability of all index and form two styles index, which are f and other bad stability index ; then, we form the valuation system, including two - layers index, which are p and factor score ; last, we use this system to analyze the close - end funds which came into existence before 2000 and get the final comparative result. the main intention of this paper is to create the system of valuating close - end funds in our country, which is comprehensive and objective. in my valuation system involving the period from 2000 to 2003, the funds as a whole performs inferior to the stock index
首先，對國外理論界經典成型的、以及前沿的基金評價指標和評價方法進行了詳細的分析，並結合我國的基金市場狀況，選取了可以衡量基金收益、穩定性、下跌風險、股票選擇能力、時機選擇能力等量化指標；其次，根據我國基金分析的需要，採用了諸如基金交易價格、換手率等二級市場表現指標；然後，對這些指標進行了時間延續性分析，檢測這些指標在運用到我國基金市場時能否有效預測基金未來表現，從而形成了兩類指標：時間延續性很好的s _ p和時間延續性不好的其它所有指標；再次，在以上工作的基礎上形成了由兩個層面的指標構成的我國證券投資基金評價體系： s _ p和因子分析中綜合因子得分值；最後，選取了我國2000年1月1日前成立的23隻封閉式基金作為樣本，並同時採用上證a股與深成a股兩個基準組合進行了3年樣本期的實證分析，得出了最終的比較性評價結果。 -
The main circuit is consisted of 18 thyristors circuit and protection circuit. with the help of control subsystem, it can get the output of low frequency voltage ( current ) with the shape of sine wave ; the core of the control subsystem is the cpu of 87c196kc, and the synchronization circuit, the pulse - widen circuit, and the power - enlarged circuit form the accessorial subsystem of the control system. it possesses all the functions of digital triggering, digital tuning, analog / digital conversion ; the input transfer can isolate the input and output ; and the circumfluence reactor can reduce the circumfluence
主迴路採用由18個晶閘管組成的三相零式電路，並輔以晶閘管的保護電路，通過控制可以得到低頻正弦波的電壓（電流）輸出；控制迴路主要以87c196kccpu為核心，其外圍電路包括同步電路，脈沖拓寬電路，功率放大驅動電路等，完成了數字觸發、數字調節、模數轉換等功能；進線電源變壓器具有變壓和隔離作用；環流電抗器則實現了有效抑制主迴路瞬時脈動環流的功能。 -
