與單向犁相比，其優點在於：耕地無開、閉壟，地表平整，降低了耕后整地的能量消耗，減少了地頭的空行程，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；同時對犁壁曲面的形狀採用了近似圓柱形的對稱設計。但經過一段時間的田間試驗，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。The theory overall illuminates how the investment company proceeds the stock choice and turns the stock choice into the concrete number by turning six factors given weights that affect the result of the stock choice into the probability of the stock choice by the quantitative method. the important points lie in : 1 considering the external environment, the growth nature, the venture and the corporate v alue ; 2 overcoming the non - comparability of the financial ratios between the corporations of different lines

本研究的結論是： 1 ）中國股票市場的微觀交易結構並不是採取做市商制度，且2 3的股票不能流通，流通股規模很小，存在著股票股利事件后的快速「填權」效應，使股票價格快速回升，股票股利發放事件的稀釋價格作用無法發揮，也就無法達到「最適價格」 ； 2 ）中國股市的買賣價差的含義發生了變化，不再是實際交易成本的反映，只是可能交易成本的反映，因而很大程度上代表了股價的波動意願，並不具有完全意義上的流動性含義。 3 ）就換手率而言，它既是流動性的衡量指標，也是最常用的衡量投機性的指標。換手率指標只能說明流動性的一個側面，在中國衡量流動性是有缺陷的。For electrodeposition by dc methods, the metals deposite uninterrupted and the particles were also embeded uninterrupted into the coatings ; for electrodeposition by pc method, the particles with biggish volume were desorbed from the coatings and returned to the electrolyte again owing to the presence of pulse interval ; for electrodeposition by prc method, the particles carried positive charges are much more easy to desorb from the coatings owing to the effecf of reverse pulse current combined with pulse interval, in addition, the reverse pulse current also could dissovle the metals, further accelerates the desorption of particles, thus the particles size embeded in the coatings by prc method is the least
直流電沉積時，基質金屬的沉積連續進行，粒子在電極表面不間斷嵌入鍍層;單脈沖電沉積由於脈沖間歇的存在使得具有較大體積的粒子會脫附，重新回到溶液中;採用周期換向脈沖時，反向脈沖電流使表面荷正電的較大的粒子更易從電極表面脫附，同時，反向脈沖電流對基質金屬的溶解作用，也會促進粒子的脫附，因此鍍層中復合粒子尺寸最小。隨著鍍層中粒子復合量的增加，三種鍍層的晶粒都明顯細化，說明al _ 2o _ 3的存在阻止了晶粒的長大，提高了電沉積過程中晶核的形成速率。Polish or sand the exterior surface of stainless steel or aluminum discal ware products, which are in the shape of squareness, roundness and oblong. it adopts computer numerical control techniques to achieve polishing automatically
