加速度

The data needs to be transferred from testers to the host computer in the testing system for real-time acceleration. For the sake of improving the controlled at real-time and the reaction rate of accepter for data, at the condition of Windows XP, the serial communication between signal PC and multistation of sensors was realized and the data collected by each sensor can be got at real time.

在实时加速度测试系统中，数据需要从测试仪传送到主机上，为了提高控制的实时性及接受端对数据的反应速度，利用VC++7.0下的Active控件和RS-232串行接口，实现了在Windows XP环境下，单台PC机与多台传感器的串行通信，并能实时获取各传感器的数据采集。

Due to their merits of low power consumption, low cost and high shock resistance, switches have a wide application in inertial monitoring system such as munition fusing, airbag system, etc.

利用MEMS技术研制的阈值加速度开关具有低功耗、低成本、过载能力高等优点，在惯性控制系统中有着广泛而重要的应用。

Two sets of measuring unit consisting of 3 accelerators in 3 mutually perpendicular directions are placed 30 m apart.

每3个相互正交安装的加速度计组成一组测量单元，两个单元之间相距30m，并相对固定。

Application of proportional controller to active vibration control incorporated with passive vibration isolator to suppress its resonant oscillation of natural frequency is proposed in this paper. Vibration acceleration acquired from accelerator is inputted to controller as feedback signal. The processed signal from controller is transmitted to voice coil actuator to control vibration.

本文主要是运用比例控制器进行被动式隔振系统自然频率共振抑制之主动控制研究，控制回馈讯号采用加速规量得之振动加速度值，经由控制器计算输出控制讯号驱动音圈致动器进行主动控制。

In the experimental work, application of proportional controller to active vibration control incorporated with passive vibration isolator to suppress its resonant oscillation of natural frequency is studied in this project. Vibration acceleration acquired from accelerator is inputted to controller as feedback signal. The processed signal from controller is transmitted to voice coil actuator to control vibration. Firstly, based on the theoretical equations which govern the system vibration, the physical mechanism of active control in total system is studied.

在实验部分，则运用比例控制器进行被动式隔振系统自然频率共振抑制之主动控制实验，控制回馈讯号采用加速规量得之振动加速度值，经由控制器计算输出控制讯号驱动音圈致动器进行主动控制。

Integrated SINS/GPS navigation system, which plays key roles in the navigation field, is also studied. The design principles and implementation problems are investigated and discussed.

陀螺和加速度计的误差，圆锥效应的补偿剩余误差对长时间工作的SINS系统的性能仍有很大的影响。

The direction of the acceleration is the direction of the net force.

加速度的方向与合力的方向相同。

Where a is acceleration, F net is net force, and m is mass.

在这里 a 是加速度， F net 是净力， m 是质量。

It is the net force on an object that acceleration.

第一章 科技英语单句写作正是在物体上的净力引起了加速度。

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

物体的加速度与所受的合外力成正比，与物体的质量成反比。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
