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。
There was a ridge of ploughed land, with a plough upon it where it had been left last night when the horses were unyoked ; beyond, a quiet coppice - wood, in which many leaves of burning red and golden yellow still remained upon the trees

Based on wide - ranging knowing the mechanical technology of overturning crops stalk into soil inland and overseas, combined with the present condition and the requirement of the mechanical technique developing, aimed at the tendency of the remained stalks heightened of food crops in south china, the thesis brings up an mechanizing technical project and mating device, which contain the function of plowing soil and overturning crops stalk on the base of plough. it is tightly packed, reliable and can be used conveniently
本文是在對國內外秸稈還田機械技術廣泛了解的基礎上，結合我國秸稈還田的現狀及其對機械技術發展的需求，針對我國南方主要糧食作物收獲
后滯留在田間的秸稈日益增高的態勢，提出了一種基於
犁耕基礎上的集土壤翻耕與高稈翻埋功能於一體，結構緊湊、使用方便、性能可靠的機械化技術方案及配套裝置。
The 2014 aluminium alloy treated by 500 solution and 165 ageing has fine alloy phases distributing equably, higher mechanical properties, thus the wear resistance is improved

后，其合金相分佈細小、均勻，力學性能較高，磨損時，在出現了
犁溝的同時，還存在粘著剝落坑，磨痕最淺，耐磨性提高。
It is observed that the topography of the area with noise on a scar surface is characterized by larger surface roughness, plowing grooves, pits or adhesive joined asperities. while it is found that the topography of the scar after noise disappearance is characterized by a clear polished scar surface and a smaller surface roughness
有噪聲磨痕形貌的特徵是表面粗糙度比較大、存在不規則的
犁溝、麻坑或粘著微凸體；而噪聲消失
后的磨痕形貌特徵是表面粗糙度比較小、有微拋光作用發生。
Along the edge of each of these something crept upon ten legs, moving without haste and without rest up and down the whole length of the field ; it was two horses and a man, the plough going between them, turning up the cleared ground for a spring sowing

Then, far beyond the ploughing - teams, a black speck was seen
