In vitro study of peripheral blood polymorphonuclear leukocyte degranulation induced by the filtrate of ultrasonic pulverization from actinobacillus actinomycetemcomitans 伴放线放线杆菌超声粉碎滤液诱导外周血中多形核白细胞脱粒的体外研究
At the same time , we give a neural network ' s topological structure , which will use to solve the concrete problem oriented to threshing performance modeling 同时针对脱粒装置性能建模这一具体问题，分析给出了用于对脱粒性能进行建模的基于ga - bp算法神经网络的实现。
Seed - husking plant is the key unit of combine , whose improvement and perfection is mainly based on the nonlinear mathematical model of the threshing performance with its influencing factors 脱粒装置是联合收获机械的核心部件，它的改进与完善是以脱粒性能与其影响因素之间的非线性模型为基础的。
The testing unit was used on experimental research of working performance and structural parameter of axial flow threshing and separating installation , scientific research and instructional system etc 该试验台可进行轴流脱粒与分离装置工作性能和结构参数的试验与研究，可用于科研、教学和生产等部门。
In order to investigate the distribution regularities of axial direction of emerging object , experimental research of paddy threshing and separation used axial flow threshing and separation installation designed by ourselves of screw vane with shutter tooth was carried on 摘要利用自行研制的螺旋叶片带板齿式轴流脱粒与分离装置，进行了水稻脱粒试验研究，目的是研究脱出物沿滚筒轴向的分布规律。
Under the uncertain conditions , the purpose of setting up nonlinear mathematical model of the threshing performance with its influencing factors is to optimize all parameters of construction and motion so that we can get the optimum threshing performances 建立脱粒装置性能与其影响因素之间非线性模型的目的就是在不确定环境下，对影响脱粒性能的各因素进行优化使脱粒装置的各个性能指标达到最佳要求。
The conclusion indicated that the effect of flexible pole tooth on threshing was better compared to rigid teeth ' s , since production efficiency was increased and the damage rate was reduced distinctly , furthermore , the un - threshed rate , impurity and power take - off frequency gotten were decreased 结果表明，相对其他脱粒齿而言，柔性杆齿质量轻，种子破碎率显著降低，未脱净损失减少，含杂率降低，发芽率高。
The paddy seeds were often broken or even damaged , and its germination rate or integral rice rate was reduced by the method of traditional half - feeding thresher , because it often impacts and sorts out paddy rice by wire - loop , rigid spike - tooth or rigid pole tooth 摘要传统的水稻脱粒系统通过刚性弓齿、钉齿和杆齿对水稻进行打击脱粒，造成水稻籽粒破碎或者籽粒内部损伤，降低了种子发芽率和大米加工的成米率。
But the unthreshed sheaves remaining untouched seemed countless still , notwithstanding the enormous numbers that had been gulped down by the insatiable swallower , fed by the man and tess , through whose two young hands the greater part of them had passed 由那个男工和苔丝喂进去的大量麦束，都被那个贪得无厌的机器吞食掉了，麦垛的大部分都经过这两个年轻人的手填进了机器，尽管如此，剩下来的还没有脱粒麦束似乎还是没有完的时候。
As tess and the man who fed could never turn their heads she did not know that just before the dinner - hour a person had come silently into the field by the gate , and had been standing under a second rick watching the scene , and tess in particular 因为苔丝和喂料的那个男工连扭头的时间也没有，所以她不知道就在吃正餐的时候，有一个人已经悄悄地来到了这块地里的栅栏门旁边。他站在第二个麦垛的下面，看着脱粒的场面，对苔丝尤为注意。
