That one ? yes , shes a good beastshe can catch a hare , ilagin said indifferently of his black and tan yerza , a bitch for whom he had a year before given a neighbour three families of house - serfs . so they dont brag of their thrashing , count , he went on , taking up their previous conversation 伊拉金用冷淡的语声谈起他自己的那只红花斑的叶尔扎，他在一年前用了三户奴仆才向邻人买下了这只母犬， “那么，伯爵，你们的脱粒的粮食不能称道吧？ ”
The work sped on till breakfast - time , when the thresher was stopped for half an hour ; and on starting again after the meal the whole supplementary strength of the farm was thrown into the labour of constructing the straw - rick , which began to grow beside the stack of corn 脱粒的工作以全速进行着，一直到吃早饭的时候才停了半个小时早饭过后，机器又开始转动起来农场上所有的辅助工人也都来堆脱粒后的麦秆，在那堆麦粒的旁边，麦秆堆也越来越大了。
As the axial flow threshing and separating equipment were used more and more widespread and the theory of threshing was not researched deeply , the axial flow threshing and separating installation with helical blade plate were triturated according to the same kind of technique experience 摘要针对轴流脱粒机在实际生产中的广泛应用和人们对于脱粒机理的研究还不深入的现状，结合国内外同类技术研究经验，研制了螺旋叶片带板齿式轴流脱粒与分离装置试验台。
In the process of threshing , the significance of factors , which influence threshing performance , not only include some certain factors such as feed quantity , cylinder rotary speed , distance between cylinder and concave , thresher concave radian but also include some uncertain factors such as the crop ' s variety , water content and the proportion of cereal straw . for this reason , the seed - husking plant is system with a character of uncertain , multi - input - output and complex nonlinear 脱粒装置的工作过程极为复杂，影响脱粒性能的因素很多，除了喂入量、滚筒转速、凹板长度与入口间隙等确定性因素外，还有作物品种、作物含水率以及谷草比等一些不确定性因素，因此脱粒装置是一个具有不确定性、多输入多输出的复杂非线性系统。
In this paper , we first analyze each factor of influencing threshing performance , and deficiency of all traditional methods such as single factor , orthogonal experiment , variance analysis and regression analysis , which have been used to study the threshing performance . in the basis of above analysis , we propose a new method of threshing performance modeling - a bp neural network . by use the new ways of threshing performance modeling - a bp neural network , we can obtain the optimum model of threshing performance , which can better describe the seed - husking plant ' s feature of complex nonlinear , multi - input - output and indefinite 本文首先分析了影响脱粒装置性能的各个因素以及传统研究脱粒性能的各种方法如单因素法、正交试验法、方差分析法以及回归分析法的缺陷，在此基础上提出了采用bp神经网络对脱粒装置性能模型进行优化，采用这种方法优化脱粒装置性能模型可以更好地刻划脱粒装置所具有的多输入多输出、复杂非线性以及不确定性等特征。
Check the state of the straw separated : if the straw is seriously broken , the cylinder and the concave must be adjusted to lessen excessive threshing ; if the straw is complete and unbroken , the quantity of wind shall be increased to make the chaff on the sieve surface the state of floating or the opening of the chaffer shall be slightly increased to make the grain fall through the sieve 检查单个稻草的状况：如果稻草严重受损，必须调节滚筒和凹面以减小脱粒过猛；如果稻草完好无损，则必须增大风量使得谷筛表面的废渣飘浮起来，或者慢慢加大谷筛孔，使得谷物穿过谷筛。
