Operation regime, configurational peculiarities, and the materials used of the piston are investigated analytically.

指出了目前矿场往复泵活塞寿命太短的主要原因，并对活塞的使用工况、结构特点及材料性能进行了分析研究。

This terrific push against the piston forces it downward, and a power impulse is transmitted through the connecting rod to the crankpin on the crankshaft.

作用于活塞上强大的推动力推动活塞向下运动，并将这一推力通过连杆传到曲轴上的连杆轴颈上。

The connecting rod is attached at one end to a crankpin on the crankshaft and at the other end to a piston, through a piston pin or wrist pin.

连杆的一端与曲轴的连杆轴颈相连，另一端通过活塞销与活塞相连。

Design Features: The unique design of the piston components: the cylindrical surface of the piston with a special treatment, so to achieve a high degree of hardness and wear resistance.

设计特点：活塞组件的独特设计：活塞的圆柱表面采用了特殊处理，故此达到很高的硬度及耐磨度。

According to the d'alembert principle, the piston moving characteristics must be identified firstly to analyze its reciprocating inertia force.

根据达朗伯原理，为分析作用在活塞上的往复惯性力，需要先确定活塞的运动特性。

This avoids the complications of the of the displacer piston linkage passing through the power piston.

这避免了在位移活塞通过活塞的权力通过联系的并发症。

The model connects piston and displacer by the damping factors due to interactive motion.

该模型引入了排出器与压缩活塞运动对另一方运动产生的阻尼，从而将排出器与压缩活塞的运动连接起来。

A beta Stirling has a single power piston arranged within the same cylinder on the same shaft as a displacer piston.

一个测试斯特林有一个单一的权力活塞安排在同一缸在同一竖井作为置换活塞。

The displacements and phase shift of piston and displacer have important effects on the performance of free-piston Stirling cooler, in this paper, at first, the merits and faults of various displacement measurement methods at present were detailedly analysed.

压缩活塞与排出器的位移大小及相位差对自由活塞斯特林制冷机的制冷性能具有极其重要的影响。

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。
