油缸

The walking mechanism of push-pull air-cushion vehicle includes two parts: push-pull mechanism and anchoring mechanism, both take hydraulic cylinders as driving components. So this walking mechanism has advantages of lighter weight and higher driving efficiency, it can work on many areas.

推拉式气垫车的行走机构包括推拉机构和抓地锚定机构两部分，它们都是以液压油缸作为驱动元件，通过液压传动实现伸缩动作的，这样既省却了轮式、履带式车辆笨重、复杂的行走机构，又大大提高了气垫车的驱动效率，能够适应各种复杂地表条件。

To improve the braking work of the swing arrestor used at the end of the marshalling yard,the mechanical property,the stroke of cylinder and the braking work is discussed.

为了提高铁路编组站尾部摆动式停车顶的制动能力，分析了摆动式停车顶的力学性能、油缸的行程和制动功，通过选择θ角的数值，来实现停车顶合理的衬套磨耗和较大的制动能力，从而提高车辆通过的安全系数和车辆编组作业效率。

The honed crosshatch pattern in the cylinder bore acts like a file to allow the rings to wear. The rings quickly wear down the "peaks" of this roughness, regardless of how hard the engine is run.

被珩磨成刀路相互交叉的油缸内孔像一把锉刀去摩擦密封环，密封环很快就将各高点磨掉，这与狠用发动机没有关系。

By two persons. Otherwise, it is easy for the cutter wheels to be damaged.

意，因为油缸的销孔是看不见的，最好有两个人操作。

Since the loader attachments are with single rocker arm, short linkage and horizontal oil cyclinder arrangement of optimal design, this loader is of the advantages of great dumping height and high working efficiency.

优化设计的单摇臂、短拉杆、卧式油缸布置工作装置，卸载高度高、工作效率快。

With the design of crossed oil cylinder greatly reduces machine's height for the convenience of transportation and maintenance

l 油缸交叉安装设计，大大的降低了设备的高度，方便运输及维修。

The results show that upper bainite and grain boundary segregation of Si element result in embrittlement of the oil cylinder.

结果表明，上贝氏体和Si元素的晶界偏聚导致油缸变脆。

By the general method and the finite element analysis, the distributing situation of the stress gradient on the oil cylinder has been gained.

采用常规方法和有限元分析，确定油缸上应力梯度的分布情况。

Through-hole oil cylinder, accommodating long bars, may be designed and manufactured to customers' specifications.

通孔油缸能通过长棒，可按客户要求进行设计和制造。

The product is applied to cylinder, oil cylinder, shock absorber and lead rail of machine tool, etc.

产品应用于汽缸、油缸、减震器、机床导轨等。

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。
