Most of the developing X-Y tables applied Ball screw-driven table system or piezo-ceramic linear motor by taking the advantages of carrying heavy loads. However, their cost are very high in contrast to the proposed architecture. In some particular application fields. Carrying heavy loads is not the main requirement for the X-Y table, such as organic cell inspection, optical fiber alignment, nano-material research, ect. Taking this idea as a premise, if we could able to create a precise positioning X-Y table with very low cost, we will be able to achieve the extremely high commercial value and highly competitive ability.

X-Y精密定位平台的开发，不外乎线性马达或压电陶瓷马达搭配导螺杆或其它机构所组成，其优点是可以承载较重之待测物体，缺点是重量大且价格昂贵，在许多应用上并不要求测试平台拥有太大的荷重能力，如生物医学诊断及检测，生物晶片开发及检测，光纤校准，奈米材料研发，奈米量测及精密全平面扫描等等，如果以此为前提，能以极低之成本创造出高精密定位之X-Y平台，将会有极高之商业价值及极大之竞争力。

We will also discuss the realistic problems about the automatic control of current source, the detection of photo signals, the selection of sample holder and other vacuum components, and photo alignments for the home-made users who want to setup their own device.

此外，亦讨论一般自行架设仪器系统可能面临的问题，例如电流源自动控制、光感测器接收、样品座与真空环境零件选用及光路校准等。

That includes aligning the ring gauge before measuring for dia.

那包括在测量直径之前排校准环规。

As a matter of interest, what size does the calibration certificate say the ring gauge is ?

稍微有点好奇，环规校准报告说环规尺寸是所少？

SB2015-3 Precision Decade DC Resistance Box adopts high voltage glass glaze resistors and special high voltage seal switch.Its electric performance is very stable and insulation intension is very high.The resistance value can be adjusted under the condition of ceaselessly opening voltage(Note:The using switch should not be at the point of 0.)It is easy to operate and suitable to be used to calibrate insulation resistance meter,and suitable to be used as high resistance standard.
