To do this you need to add a "d: DataContext" property to the same object that will get the real data context.

为了达成这一点，需要向接收实际数据上下文的对象增加一个“d： DataContext”属性。

Some key technologies are discussed such as video cameral calibrating, laser plane calibrating 3-D coordinate computing of measured object and data fusion of multiple view measurement.

探讨了摄像机标定、激光平面标定、被测物体点三维坐标计算及多视角测量数据融合等关键技术。

Through Laser 3-dimension Scanning technology the 3-d model of static object can be acquired fast, precisely and multi-directionally, the model and its data can be analyzed and proceed further.

激光三维扫描技术能够快速、精确、多方位地获取静态物体的三维模型，并对模型进行进一步的分析和数据处理。

And the problem is, that we want to build this abstract data type, but we'd like to basically know what kind of object is it, and what functions actually belong to it, how do we use them?

然后我对它们运行了这个方法，就是这一小段代码这个方法,这有意义么？,当然没有了，对不对？,因为你知道，当你把两个极坐标，表示的点进行相加运算的时候？
