Based on the relationship between the numerical aperture of the objective lens and scale pitch, this study chooses a suitable Plano-convex lenses available on the market, so as to approximate the diameter of the focusing spots to scale pitch. Also, by using the optical path of an optical encoder similar to the nanoscale, the changes in the surface profile of the scale can be measured directly, so as to obtain the two quadrature sinusoidal signals. By counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the scale can be obtained.

研究中再以搭配物镜的数值孔径与尺条间距的关系，选择ㄧ适当的市售平凸透镜，使聚焦光点的直径与尺条的间距相近，并使用相同於奈米级长行程双雷射聚焦读头装置的光路设计，如此将可藉由直接量测尺条的表面轮廓变化，以获得一组正交弦波讯号，继而利用讯号四分割与细分割处理，计算出尺条之移动方向与移动量，研制出一实用性长行程双雷射聚焦读头光学尺。

How unlikely, that a short-lived biped on a two-bit planet should be able to gauge the speed of light, lay bare the structure of an atom, or calculate the gravitational tug of a black hole.

想想这一切是多么地不可思议：在一个不起眼的星球上，生存着一种拥有短暂生命的两足生物，然而，正是这些微不足道的小生物，不但测量出了光速，而且把原子层层剥开，还计算出了黑洞的引力。

When proceeding pump testing, we collect a good many parameters, and figure out the pump gross head, pump shaft power, NPSH and other parameters. Different units of those parameters are used in different countries, and sometimes the customer asks for the test data of special media. Making a test of every medium of the same pump is not realistic, and the costs will be increase, so we convert the units of the data, and figure out the testing data according to different customer's special requirements. We reduced costs and got good remarks from the corporation through the application of unit conversion technology.

水泵试验时，要采集诸多参数，并且根据这些参数计算出扬程、轴功率、NPSH等数值，不同国家这些参数采用的单位不同，企业必须能够按照客户要求的单位提供试验数据；并且有时客户要求得到水泵在特殊介质下进行试验得出的试验数据，同一台泵在每种介质下都做一遍试验不太现实，而且会提高企业的生产成本，提出将采集的数据进行单位换算，根据不同国家或者客户的特殊要求求出泵的试验数据，在实际应用中节省了试验成本，得到了企业的好评。

There are several ways toobtain the DBHF self-energy from the G matrix used before, such as a simple method,where the Dirac structure of the nucleon self-energy is obtained from the momentumdependence of the single-particle energy, and a projection method.
