Jt91 - 200 artillety gyro altazimuth is a fix instument which can research the grid north automatically and determine grid north azimuth at any direction . it works by making use of the physical features of gyro and influences of earth rotation . the equipment of this instument will play a important role in topographic clement Jt91 - 200型炮兵陀螺經緯儀是利用陀螺本身的物理特性和地球自轉的影響,實現自動尋找其北方向和測定任一方向線的真北方位角的定向儀器。該型炮兵陀螺經緯儀的裝備使用,對我軍炮兵測地分隊的測地保障發展將產生重大影響。

E . g . the ge lens used in planar wide - angle altazimuth , indirect ophthalmoscopy lens in ophthalmic diagnosis , zoom lens of camera , all were minor aspheric component 例如,紅外廣角地平儀中的鍺透鏡、眼科診斷用的間接眼底鏡、變焦照相機鏡頭、刻錄機光頭等都是小型的非球面元件。

In the paper , the testing scheme and making of a aspheric ge lens that used in planar wide - angle altazimuth was described 就平面廣角地平儀設計中用到的一塊非球面的小型鍺透鏡作了檢驗設計和加工。
