When a StreetViewPanorama first loads, by default it displays an image consisting of 25% (90 degrees of arc) of the horizontal breadth of the panorama at zoom level 1.

当一个谷歌街景图像初次载入，默认情况下，它处在缩放等级 1，这时显示了整 张全景照片 25%的水平宽度（90度的水平视野）。

This new-style sensor can move to-and -fro along the horizontal direction. Thus it can actualize the multi-point, itinerant measure of film along the direction of breadth.

由于这种新型传感器可以沿导轨在水平方向上往复位移，所以在被测薄膜的幅宽方向上可以实现多点巡回检测。
