In continuous casting course, the liquid core length is a very important parameter, it reflects the cooling condition of casting and the appropriate degree of pulling speed.

在连铸生产工艺中，连铸坯的液芯长度是连铸生产中一个非常重要的参数，它直接反映了铸坯冷却的状况和拉速的合理程度。

The factors of temperature and humidity influenced on film thickness and order of layer were studied, in which pulling speed and pulling times were also included.

考察了温度、湿度、提拉速度、提拉次数对膜厚、膜层有序性的影响。

Then I have obtained system parameters through the design of identification experiments, which can be used to establish the parameter model of the pulling speed control diameter system.

再通过设计辨识实验得到系统参数，用于建立控径系统的参数模型。

And there is such a thing as driving too slow, as you can tell from the viral videos of cops pulling cars over for going under the speed limit and impeding traffic.

People eyeing the Air for its speed, thinness and beauty should also give the Samsung Series 9 a long, hard look before pulling the trigger.
