  2. In the course of working, , the plow will make use of the shuttling method so that it can dig alternately either on the left or on the right. compared to the unilateral plow, it can improve the productivity because it can help leave off the soil 、 take from the consumed energy and reduce the empty journey. to meet the requests above, we will use a remote cylinder with both a small cubage and double functions, approximately designing the plow to be columniform and symmetric. after the experiment for a period in the field, we found that the most frayed areas had happened at the places of both plow shank and share and at the same time the base of the remote cylinder had ruptured suddenly

    與單向犁相比,其優在於:耕無開、閉壟,表平整,降低了耕后整的能量消耗,減少了頭的空行程,因而大大提高班次生產率。為了滿足犁體梭式作業的要求,我們採用了一隻小容積雙作用的液壓油缸;同對犁壁曲面的形狀採用了似圓柱形的對稱設計。但經一段的田試驗,我們發現:該犁犁胸部分的犁脛和犁鏵上的犁尖在工作中磨損較為嚴重;主犁梁和油缸缸體的連接部分(即油缸底座)突然發生了斷裂,造成整個犁體無法正常工作。

  4. With the steady growth of natural gas, the recent hot spot of world sources of energy and with the encouraging progress in such renewable sources of energy as solar energy and wind energy, the proportion of oil in the world ' s unrenewable sources of energy has indeed been lower than before ; nevertheless, upon comparing with natural gas, nuclear energy and other sources of energy, it has been found out that the dominance of oil in the world ' s unrenewable sources of energy will remain unshakable in the coming 20 years though after that period of time there may be intense competition between oil and natural gas for supremacy. although people have been repeatedly made a fool of by the unpredictable oil price and made one misjudgement about it after another, yet given the world general situation of oil supply and demand, the essential variable, with which the oil price will continue to vary, plus other factors, such as the oil price policy of some middle eastern oil producers which is tending more and more rational, it can be roughly concluded that the world oil price will be stable with a slight rise

  6. By successful solution of non - linear magnetic fields and revision of the program, we can reach following conclusions : in the computation of nonlinear magnetic fields, if iteration method is used, under - relaxation is necessary when amending the permeability distribution in soft magnetic materials ; and when < wp = 5 > calculating the equivalent current density in permanent magnets, under - relaxation is not a necessity ; when searching for permeability values by interpolation method on the demagnetization curve of soft magnetic materials, if a fixed saturation point is set, around this point an abrupt change of permeability values will be obtained ; this sudden change may cause a little problem in the smoothness of magnetic field distribution ; because the magnetic circuits of microwave tubes are too complicated, in the author ' s view, to describe the working state of a magnet system, the working points of magnets can not do it properly but average energy production of magnets will serve ; as to indicate the quality of a magnet system design for microwave tubes, the efficiency of magnetic energy utilization will be a very good criterion

    由此得出結論,在非線性磁場計算中:採用迭代法的情況下,在各迭代循環之進行磁導率修正,一個欠鬆弛迭代程是必需的;對永磁體中的等效電流修正可以不作欠鬆弛迭代;在純鐵的磁化曲線上指定某一個固定的磁感應強度為磁飽和值,會使得插值求出的磁導率在該磁飽和值附有一突變,這一突變對計算結果中磁場分佈變化的光滑性稍有影響。在微波管磁系統設計中,由於微波管磁路比較復雜,作者認為磁體的工作並不能很好反映磁體的工作狀態,而採用平均磁能積為衡量磁體工作狀態的標準更加符合微波管磁系統的實際情況;要表示磁系統設計好壞的程度,則用磁能利用的效率為標準更好。

The empirical research in em forthers the acaden1ic thoughts of accrual - basis accounting, hastens the development of generally accepted accounting principles, and enriches the research measures in empirical accounting lots of literatures on em have been reported rece11tly however, researcheres have n ' t reached the consensus in most issues in this fieid much of the controversy over the interpretation of the literature ' s tindings is due to the extensive use of aggregate accruals models that mostly origil1ated from jones mode1 given the limlted theory, we have of how accruals behave in the absence of discretion, the task of identifying and controlling for potentially correlated o111itted variables is daunting indeed an alternative to study aggregate accruals is the 111ethodology for identifying earnings management developed by burgstahler and dichev ( l997 ) based on the distribution of earnings after management however, this measure is flawed by its silence about the form and extent of earnings management my dissertation intends to bridge the traditional aggregate accruals models and the new earnings distribution method, which is the first aim of this paper there is no doubt that earnings management is more rampant in china when compared with what has been documented for the west, since china ' s accounting standards are much too incomplete to of lbr clear guida11ce on many accounting transactions

    文章首先指出了研究盈餘管理的三種方法各自的優及不足,然後創造性發展了前人的研究手段,在傳統的瓊斯模型及新的盈餘分佈方法之找到了溝通的橋梁,並建立了一個嶄新的模型:瓊斯?閾值模型。通對美國18 , 160家上市公司在1980 - 1999的20年的40餘萬觀測樣本的實證研究表明,美國上市公司與我國上市公司一樣也存在著以獲取正盈餘及維持期業績為目的的盈餘管理;公司經理人員使用可操縱性應計利潤為其管理盈餘的手段;經理人員因追求正盈餘或試圖維持期業績而管理盈餘體現出不同的行為方式。對美國上市公司的成功運用,證明我們的新模型在判斷盈餘管理存在與否、手段如何、動機怎樣等方面均比目前正在學術界流行的盈餘分佈法具有更強的檢測能力。
