Absolute accuracy : Deviation between the actual position ａnd the desired one. If a stage has to move 100µm but it moves only 99.99µm (measured through an ideal scale), then the inaccuracy is 10nm. The permanent positioning error along an axis is designated as accuracy. Absolute accuracy is aff¬ected by calibration errors, linearity errors, hysteresis, Abbe errors ａnd positioning noise.
绝dui精度：实际位置与所需位置之间的偏差。 如果一个平台必须移动 100µm，但它仅移动 99.99µm（通过理想标尺测量），则误差为 10nm。 沿轴的泳久定位误差称为精度。 绝dui精度受校准误差、线性误差、滞后、阿贝误差和定位噪声的影响。
Backlash : Backlash is a positioning error occurring upon change of direction. Backlash can be caused by insufficiently preloaded thrust or inaccurate meshing of drive components, for example gear teeth. Piezoconcept’s flexure motion translation mechanism ａnd piezo actuator designs are inherently backlash free.
齿隙：齿隙是在运动方向改变时发生的定位误差。 齿隙可能是由于预载推力不足或驱动部件（例如齿轮齿）啮合不准确造成的。 Piezoconcept 的弯曲运动平移机构和压电致动器设计本质上是无间隙的。
Bandwidth : The frequency range to which the amplitude of the stage＇s motion is dropped by 3dB. It reflects how fast the stage can follow the driving signal.
带宽：载物台运动幅度下降的频率范围为3dB。 它反映了平台能够以多快的速度跟随驱动信号。
Drift : A position change over time, which includes the e¬ffects of temperature change ａnd other environmental e¬ffects. The drift may be introduced from both the mechanical system ａnd electronics.
漂移：位置随时间的变化，包括温度变化和其他环境影响的影响。 漂移可能来自机械系统和电子设备。
Friction : Friction is defined as resistance between contacting surfaces during movement. Friction may be constant or speed dependent. Because they use flexure, the nanopositioners from Piezoconcept are friction free.
摩擦力：摩擦力定义为运动过程中接触表面之间的阻力。 摩擦力可以是恒定的或取决于速度的。 因为使用柔性连接，Piezoconcept 的纳米定位器是无摩擦的。
Hysteresis : The positioning error between forward scan ａnd backward scan. A closed-loop control is an ideal solution for this problem ａnd is done by using a network of High Resolution silicon sensor to provide feedback signals.
滞后：前向扫描和后向扫描之间的定位误差。 闭环控制是该问题的理想解决方案，它通过使用高分辨率硅传感器网络提供反馈信号来完成。
Linearity error : The error between the actual position ａnd the first-order best fit line (straight line). Our nanopositioning products are calibrated with laser interferometry ａnd the non linearity errors are compensated down to 0.02% of the full travel.
线性误差：实际位置与一阶蕞佳拟合线（直线）之间的误差。 我们的纳米定位产品使用激光干涉仪进行校准，非线性误差补偿低至全行程的 0.02%。
Orthogonality error : The angular off¬set of two defined motion axes from being orthogonal to each other. It can be interpreted as a part of crosstalk.
正交性误差：两个定义的运动轴相互正交的角度偏移。 它可以解释为串扰的一部分。
Position noise : The amplitude of the stage shaking when it is on a static command. It is usually measured ａnd specified with Peak-To-Peak value. It is a combination of the sensor noise, driver electronics noise ａnd command noise, etc. The position noise of our stages is very limited due to the very high Signal-To-Noise ratio of the Silicon HR sensors we use.
位置噪声：在静态命令下载物台晃动的幅度。 它通常用峰峰值来测量和指ding。 它是传感器噪声、驱动器电子噪声和命令噪声等的组合。由于我们使用的 Silicon HR 传感器具有非常高的信噪比，我们平台的位置噪声非常有限。
Range of motion : The maximum dISPlacement of the nanopositioners.
运动范围（行程）:纳米定位器的蕞大位移。
Resolution : The minimum step size the stage can move.
分辨率:舞台可以移动的蕞小步长。
Resonant frequency : Piezostage are oscillating mechanical systems characterized by a resonant frequency. The resonant frequency that we give is the lowest resonant frequency that can be seen on a nanopositioner. In general, the higher the resonant frequency of a system, the higher the stability ａnd the wider working bandwidth the system will have. The resonant frequency of a piezostage is determined by the square root of the ratio of sti¬ness ａnd mass.
谐振频率：压电级是以谐振频率为特征的振荡机械系统。 我们给出的共振频率是在纳米定位器上可以看到的蕞低共振频率。 一般来说，系统的谐振频率越高，系统的稳定性和工作带宽就越宽。 压电级的共振频率由刚度和质量之比的平方根决定。
Silicon HR sensor : Piezoconcept use temperature compensated High-Resolution silicon sensors network for reaching highest long-term stability. This measuring device is capable of measuring position noise in the picometer range ａnd its response is not dependent of the presence of pollutants, air pressure changes like other high-end sensors can be.
Si-HR 传感器：Piezoconcept 使用温度补偿高分辨率硅传感器网络，以达到蕞高的长qi稳定性。 该测量装置能够测量皮米范围内的位置噪声，并且其响应不依赖于污染物的存在，应对改变气压带来的影响与其他高duan传感器一样。
Step response time : The step response time is the time needed by the nanopositioner to do the travel from 10% of the commanded value to 90% of the commanded value. The step response time reflects the dynamic characteristics of the system ａnd is relatively to the installation method ａnd load of the stage.
阶跃响应时间：阶跃响应时间是纳米定位器从指令值的 10% 到指令值的 90% 所需的时间。 阶跃响应时间反映了系统的动态特性，并且与位移台的安装方式和负载有关。
