Options include automatic cable tensioning, single-acting models, cable tracks for greater load stabilization and capacity, a pulley arrangement to double the stroke and speed, caliper disc brakes on the cable pulley, and reed switches.

选配件包括自动钢索张紧，单动模型，用于稳定和增大载重量的钢索链条，可使冲程和速度翻倍的滑轮结构，钢索滑轮上的盘式刹车卡钳，以及簧片开关。

By means of the K-ε turbulence model and finite element method, the flow of the fluid in the valve and the piston during a cycle of pumping is simulated and calculated. The motion law of the crude oil in the valve passage and concentric annulus in the upstroke and downstroke is analyzed.

针对杆式泵泵简内的流体流动问题，采用湍流模型的K-ε两方程模型和有限元方法，对在一个抽油循环中阀与活塞在几个特定的位置的流体流动进行了建模与计算，具体分析了处于阀道内和同心环状空间中的原油在上下冲程的运动规律。

On the principle of both work and energy equalization during the upstroke and downstroke, the writer analyses an approximate calculating method of rotary balance acquired by this type of the beam pumping unit.

本文根据抽油机上下冲程功能相等的原则，分析了前置式抽油机取得旋转平衡的近似计算方法。

The instantaneous gearbox torque at a given polished rod position (whether on the polished rod upstroke or downstroke) is the torque factor at that polished rod position multiplied by the net gearbox load at that position.

在一个指定光杆位置的瞬时变速箱扭矩（无论是上行还是下行冲程）等于那个光杆位置的扭矩因数乘以那个位置的变速箱净载荷。

We started with a powerful 12", long-excursion low frequency driver for abundant bass punch and accurate low midrange. Next we joined a high-resolution 1" HF driver for clarity and brilliance with a groundbreaking horn design, ensuring smooth frequency response and ultra-wide sound dispersion so you can move around the stage.

这款产品配有功率强大的 12 英寸长冲程低频驱动器，提供铿锵有力的低音和精准的中低频；高解析度 1 英寸高频驱动器和设计新颖的号筒，提供明亮通透的高音，确保平滑的频率响应和极大的声音扩散角度，使你能在舞台上自由跑动。

This is very similar to a 2-stroke engine.

这是非常相似的2冲程发动机。

Professional long throw slide faders with a fader range switchable from 6dB to 12dB allow for precise adjustments allowing you to get the best possible sound from your rig in the situation you are faced with.

专业长冲程的推子范围从分贝幻灯片切换到12dB的推杆让让你从你在你所面临的形势造最好的声音精确调整。

The plunger or piston of a force pump or hydraulic press.

蒸汽机或其他发动机的活塞离开曲轴运动时的冲程。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
