南行进入了迷雾氤氲的山谷,沿著一条叫咖啡路的道路前行,在接近午时我看到了一个咖啡园的招牌指向一条陡上的岔路,正是我喜欢的类型!
Heading south into the misty hills i discovered a route called the coffee road. This is exactly my sort of road! Around midday i saw a sign for coffee pointing up steep side road, which i followed.
主要河流有陡河、沙河、黑沿子排干、西排干、津唐运河、煤河等。
The main rivers are Douhe, river, and along the sub-draining, draining the West, Jin Tang Canal, coal river.
通常的脉冲发生器只是在电阻性负载时才能得到陡的上升沿。
General pulsers can obtain sharp risetime only when it is used for a resistive load.
同时,高速交流传动机车广泛采用高开关频率器件的脉宽调制(PWM)逆变器,使得逆变器输出脉冲具有陡上升沿。
Meanwhile, PWM inverters using high switching frequency device that shortens the rise time of PWM output pulse have been widely applied in high-speed AC driving locomotive.
对模拟局部放电的窄脉冲和陡前沿脉冲沿电缆的传播特性进行了实验研究。
The propagation characteristics of a simulation partial discharge (PD) pulse and a steep front pulse in the XLPE power cable are investigated.
结果表明:破波压力从坡面向内部传递与方向、坡度没有明显关系,而与波陡、沿程相对位置相关。
The findings show that the aforementioned wave pressure is independent of wave direction and broken stone slope, but influenced by the wave slope and the location of measurements.
然而,逆变器输出的PWM(脉冲宽度调制)连续高压脉冲的上升沿很陡、频率很高,导致在脉冲电压下牵引电机绝缘过早失效。
However, Pulse Width Modulation (PWM) which was input from inverter is characterized by steep rising edge and high frequency, resulting in the too early failure of motor insulation.
当激光器上升沿变陡时,在有效作用时间内温度上升得更快,对加工区域周围热效应的影响明显减弱,而热扩散距离变小。
When the rise time is steeper, the temperature rises faster, and the surrounding of the machining filed are less affected while the distance of the thermal diffusion reduces.
在西山和王家沟一带,为一套向北陡倾的反射层系和一组沿层间滑动的断裂;
In the Xishan and Wangjiagou area, it shows a set of steeply north-dipping reflective layers and a group of faults slipping along the layers.
我们沿第三高速向南行驶,第二天下午,我们途径一条陡径,堪与咖啡克里克的北岔路口相媲美,沿咖啡克里克路约1 2英里。
Driving south on Highway 3, the next afternoon we hiked along a steep trail that parallels the north fork of Coffee Creek from a trailhead that can be found about 12 miles in along Coffee Creek Road.
