查询词典 speed limit

The temperature-monitoring instrument for optical fiber transmission high- voltage switch contact point developed by this project has been conducted pilot testing in Sichuan Electrical Facilities Corporation and Gansu Tianshui Electrical Facilities Plant. Rectified by a standard .thermocouple temperature-measuring instrument, the testing results in situ showed that the temperature-monitoring instrument has fast response speed, accurate location for temperature arising over set limit, small measurement error within ?

本课题所研究的光纤传输高压开关触头温度监测仪分别在四川电器股份有限公司和甘肃天水电器厂进行了现场实测，并采用热电偶测温仪校验，实测结果表明：该温度监测系统反映速度较快，温升越限定位准确，测温精度误差在±1℃以内，具有较高的可靠性、安全性和经济性。

It still does not have a 6 speed box, but I'm not sure it needs it. 5 speeds are enough, but like most cars these days, it is still revving too hard at the highway limit.

它仍然只有五前速，但我感到它不需要六速，但像其他的汽车，於高速公路上，引擎仍然转数高了一点。

关键技术分别为多局部通风机故障诊断和冗余控制技术（包括掘进工作面供电系统多源信息融合、故障测寻、故障诊断、多局部通风机三重冗余控制方法和控制策略等）；综采工作面大型设备的智能控制技术（包括电气防爆技术、本质安全型控制电路设计、刮板输送机双机双速拖动重载控制技术等）；瓦斯无超限安全高效排放技术（包括风量控制策略、控制方法等）；矿井电网安全供电的故障保护技术（包括两级选择性漏电保护和相敏保护技术等）。

To regulate the spindle speed to the stable region can not only make the cutting process stable and achieve excellent workpiece surface, but also improve the metal removal rate by enlarging the cutting depth . The experiment results show that the limit cutting depth can be greatly improved.

将机床主轴转速调整到稳定区工作不但可以使切削过程稳定，获得优良的加工表面，而且可以通过进一步增大切削深度提高机床切削效率，本文对优控主轴转速下机床切削系统的极限切削深度进行了试验考证。

In each new generation the components are smaller than they were in its predecessor, and the speed at which this miniaturisation is happening means that within 15 years or so a fundamental limit will be reached.

每推出的新一代计算机，其组件都比前代的小。这种小型化发生的速度意味着在大约15年之内，计算机的体积将缩小到一个基本的极限。

As the boat is going downwind, the apparent wind is less than the true wind and this, allied to the fact that the sails are not producing aerodynamic lift, serves to limit the downwind speed.

由于该船正在顺风，风明显少于真正风能和本，有关这一事实，即帆没有产生气动升力，有助于限制顺风速度。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
