油缸

This multi-pattern steering system has independent suspensions and each group of wheels can circumrotate separately. The rotation of each group of wheels is implemented with valve controlled hydraulic cylinder which revolves the gyrate bearing through mechanical linkage.

采用独立悬挂、各轮组独立转向的多模式转向系统；由阀控液压油缸通过连杆机构带动回转支承旋转来实现各轮组的转动；在位置P ID算法的基础中加入数字补偿的控制方案。

Finally, gyrator pressure cylinder was designed to enhance.

最后对回转器加压提升油缸进行了设计。

Gyrator is used mainly driven rotary drill, and drill through the feed tank to achieve decompression of drilling increases.

回转器主要是用来带动钻具回转，并通过进给油缸实现钻具的加减压钻进。

Gyrator mainly by the following components: vertical, vertical conduits gyrator box, connecting plates, pressing beam, cylinder, bevel gear and other large arc.

回转器主要由以下几部分组成：立轴、立轴导管、回转器箱体、连接盘、压梁、油缸、大圆弧锥齿轮等。

The positions of each bar in the mechanism and various commonly used driving types are studied by vector analysis. Based on the study on the parameters of driving oil cylinder and the forces applied at each pivoting point, the inberent laws between each datum are hereupon obtained, it provides a valuable information for designers.

本文用矢量法对举升机构中各杆的位置及常用的几种驱动型式进行了分析，对骓动油缸的参数、各铰点所受的力等进行了探讨，从而得出各量间的内在规律，为设计人员提供了有价值的参考。

And the master idler wheel works together with the top left and right pressing wheel through the up/down lifting of the hydraulic cylinder in the bottom to realize the straightening on the flange that distorted after welding.

而且主动滚轮又通过底部液压油缸升降，与上部左右压轮一起，实现翼板焊接变形的矫正。

The side bearer loading and center plate hauling are adopted to the bogie, the equalized cylinder is fitted above the journal box.

转向架采用旁承承载、心盘牵引方式，在轴箱上方设有均载油缸。

The working pressure of overfall valve is too low (although oil-pipe is calefactive, cylinder does not work ) or the taper valve with dislocation and mechanism dust in plane of taper valve

溢流阀工作压力太低（尽管油管升温，但油缸不工作）；或锥阀脱位；锥阀阀面粘有机械杂质

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
