The rev-limiter kicks in at 10,300 rpm, so we were running in the upper 9K's constantly on the few short freeway jaunts we forced upon it.

在转速限制器踢在10300转，所以，我们一直在上9K的不断的短短高速公路jaunts我们强加于它。

The control box is not justing driving the actuator motor left or right, but it can drive it at different speeds, this is of course depending on how far the preset RPM is from the actual RPM.

控制箱是不是justing驾驶驱动电机向左或向右，但它可以驱动器，它以不同的速度，这当然是视乎有多远预设RPM的是从实际每分钟转速。

Assembled by Kawasaki Heavy Industries, the metre-gauge locos have Toshiba electrical equipment and diesel engines from U. S.a. These are rated at 3,200 hp, but they are derated on site to give a continuous output of 2,400 hp at 1,500 rev /min.

这批轨距为1米的柴油机车装有东芝的电气设备和美国的柴油发动机，并由Kawasaki重工组装，其功率为3200马力，但在实际使用中功率将降低为2400马力，转速为每分钟1500转。

They induce a greater amount of spin from lofted shots, as well as a sensation of softness in the hands in short-range shots.

在大角度的挥杆下将会提高转速，同时会带来短距离击球时柔软的手感。

It is proved that, while tested on short duration testing rig, the turbine power, rotation rate and flow rate require special testing method, and that, for testing the overall turbine performance, the short duration testing rig equals to, and even outruns continuous testing rig in accuracy. All the parameters need to be tested synchronically.

指出： 短周期涡轮试验在功率、转速、流量等参数的测量方法上有其特殊性；在总的涡轮性能测试指标上短周期涡轮试验完全可以达到，甚至超过连续式涡轮试验的精度；在短周期涡轮试验中，需特别注意各测量参数的同步性。

In chapter 2, based on analysis for the existed methods of torsional vibration measurement, a novel measuring method, parallelling dual-beam laser doppler torsional vibration measurement is first put forward by the author, it not only divides translation and rotation of the rotor, but also can be used to measure torsional vibration of non-cylinder rotor.
