The author has finished the following several jobs in core of the centre : 1 ) the active compensation method based on bang - bang control was put forward to realize the wide range current transformer. the method converts the complex statement space to i / o description by the two - stage current transformer. with the compensation method, the accuracy of 0. 2 grade current transformer can be improved to less than the 0. 1 grade standard at 100 % rating when the primary side current is changed from 2 % to 120 % of the rating
圍繞這一工作核心，作者完成了以下幾項工作： （ 1 ）以實現寬量程電流互感器為目標，提出了基於bang - bang控制的有源補償方法，採用雙級電流互感器，將復雜的狀態控制分量轉化為偏差控制，該方法結構簡單，調試方便，有源補償器輸出電流小，可以將0 . 2級的電流互感器經過補償后提高到一次電流從額定值的2變化到120時，測量誤差不超過一次電流額定值100時準確度為0 . 1級的測量標準。And some experts even believe, the trend in the development of the iax system was, for quite some time, towards keeping high statutory tax rates, but simultaneously provide generous tax incentives tha t reduced the tax base. the basic asymmetry of tax system may favor large concerns, which may be in a better position to take advantage of the provisions in the tax code in certain states of nature. the result may be lower expected average and marginal tax rates, and a lower cost of capital, compared to newer and smaller companies
更有學者認為，在以往很長一段時間里，稅制的發展趨勢是高法定稅率，同時附加大量稅收激勵來縮小稅基，稅制的這種基本不對稱性對大公司有利，可以面對低預計平均和邊際稅率以及低資本成本，然而大公司基於其擴張性的組織結構，與富有彈性的內容提要小公司相比，它轉變供求狀況的適應能力相對遲緩，那麼偏祖于大公司的稅收政策可能會阻礙宏觀經濟增長率和結構調整。Analyze item by item the position of unintact cycle, the running clearance of unintact cycle, locking - deform, datum dimension regulating, repeatly install, power voltage wave and marking running etc. at the same time, we give the calculating formula to calculating the running marking random error, and use it to calculate the system error of big diameter measure instrument - - datum dimension frame error, gyro - wheel diameter error, error caused by circumstance temperature, error caused by backing distance, angle error, delay error of data collecting circuit, lathe main shaft running error, workpiece install partial error
對不完整圓的位置、不完整圓的轉動間隙、鎖緊變形、基準尺調整、重復安裝、電源電壓波動、標記轉動等隨機誤差進行了逐項分析，並給出轉動標記隨機誤差的計算公式。對大直徑測量儀的系統誤差?基準尺尺架誤差、滾輪直徑誤差、環境溫度引起的誤差、後退距離引起的誤差、角度誤差、數據採集電路延時誤差、車床主軸回轉誤差、工件安裝偏心誤差分別進行了計算，最後對誤差進行合成。On such a basisthe commonly used monomial error accumulating totals correction method is introduced. the author proposes a coordinate transformation method to deal with its drawbacks of maths model imperfection, not applicable to lange - angle deviation and adding to the difficulties of equipment. while orientating the order of matrices according to the principle of the accordance between coordinate ' s rotating order and the physical process of device measuring, a strict maths model of the influence of axis system deviation on surveying angles is concluded and the corresponding correction method is induced. its far - reaching meanings are as follow : ( 1 ) the maths model of the influence of axis system deviation on surveying angles established by the new method is concluded after considerations for the three deviations simultaneously. changes under all circumstances are included, so it is theoretically a perfection of maths method
在此基礎上介紹了國內目前採用的軸系偏差對測量角影響的經典改正方法?單項差累計改正法，並針對該方法存在的數學模型不完善、對大角度偏差不適用、增加設備調整難度等缺陷，提出採用坐標變換方法，並根據坐標的旋轉次序與設備測量的物理過程相符合的原理定位各矩陣的先後順序，推導出了軸系偏差對測量角影響的嚴格數學模型，歸納建立了相應測量角的改正方法。The purpose of this paper is to find out the characteristics of corporate restructuring and reorganizations under the background of strengthened supervision and improved accounting standards in 2001. using financial data on chinese public firms that had performed restructurings in 2001, this paper studies the impact of restructuring activities on firms " performance. it finds that performance of sample companies are better than the market average both before and after restructuring, but financial ratios does not improve obviously, what ' s more, the roe ratios even drop generally, which are very different from the characteristics during the past few years
本文採用以財務數據為基礎進行評價的方法，對2001年上市公司資產重組進行研究發現，從資產重組的方式來看，收購兼并所佔比重最高，業績較好的公司偏向于選擇這種重組方式，而資產置換、股權轉讓仍為績差公司所青睞；從重組前後財務指標的變化來看，重組公司表現優於市場平均水平，但與往年重組公司當年業績即得到明顯提升不同， 2001年重組公司財務指標並未得到顯著提高，凈資產收益率更是全面下降，統計對比不支持上市公司利用資產重組調節公司績效的觀點。It is analyzed through the research that the main restricted factors affected the rural agricultural extension organizations in yi zheng lies in : the unconsummated of management mechanism, the serious shortage of the fund of agricultural extension, the unsteadiness of the rural agricultural extension group, the overall low capacity of the people, not quite properness of the professional knowledge structure, the low speed of the knowledge updating, unclear goals of part rural agricultural extension organizations, the phenomenon of not so well relationship among agricultural research, education and extension, scattered one household of the agricultural production way concerning lack of agriculture technique demanding elasticity, etc. agricultural extension has presented some new diversions under new condition of agricultural development
根據調查分析，影響儀征鄉鎮農業推廣機構發展的制約因素主要有：管理體制不健全，農業推廣經費嚴重不足，鄉鎮農業推廣隊伍不穩，人員整體素質偏低、專業知識結構欠合理、知識更新緩慢，部分鄉鎮農業推廣機構發展方向不明，目前的農業科研、教育與推廣存在相脫節現象，一家一戶的分散的農業生產經營方式對農業技術需求彈性不足等。新形勢下的農業發展對農業推廣的要求也發生了新的轉變。This fuzzy controller can implement real - time regulation of the motor ' s rotational speed in light of the position error and its variable rate, therefore, the system can run in the direction of cutting down the position error with maximum speed when the system is under the condition of a higher position error. when the error is slight, the fuzzy controller also can reduce the motor ' s rotational speed gradually, thus the precision of the system will play a dominant role, which can create good conditions for an accurate stop when the position error diminished
模糊控制器可以根據位置誤差的大小以及位置誤差變化率的大小，實時的調節電動機的轉速，使系統在大的位置偏差的情況下能夠以最快的速度向著減小位置誤差的方向運行，在小誤差的情況下，能夠使電機的運行速度逐漸減小，使系統控制的精確性佔主導地位，為位置誤差等於零的時候能夠做到準確迅速的停車創造條件。This article examines change of efficiency and equity in three development stages of urban and rural relationship ; analyzes several problems, such as urban - biased strategy dual loss of efficiency and equity under the planning system, adjustment of urban and rural relationship in the process of marketization reform, and the unequilibrium between efficiency and equity ; discusses the countermeasures for giving priority to efficiency with due consideration to equity in the new stage of urban and rural harmonious development ; suggests some policies. such as further promoting urban and rural marketization reform, encouraging consolidated and harmonious development of urban and rural productive element markets, strengthening the state ' s transfer payment for agriculture, the countryside and the peasants, and gradually transiting to a new stage of industry repaying agriculture or the urban area supporting the rural area in return
