塑變值-
Many functions such as field information map, contrastive map of yearly yield, prescription map, etc. can be made. in order to improve using accuracy of agricultural gps, by analyzing the error of point, polyline, polygon, several methods are produced such as arithmetic average value, least squares, adding control points, etc. their principles, features and limitations are also analyzed and discussed. the mathematic model of average error method included in adding control points is established
為了進一步提高農用gps的使用精度,研究了提高精度的方法,通過對點、線、面等誤差的分析,提出了應用算術平均值法、最小二乘法、加入控制點法等多種提高精度的方法,分析和討論了它們的原理、特點與應用局限性,並建立了加入控制點法中的誤差平差法的數學模型。 -
434 we shall take the sample to test its physical properties ( mechanical properties, tensile strength, yield point, percentage elongation, reduction of area, impact value, brinell hardness )
我們將取樣試驗其物理性能(機械性能、抗張強度、屈服點、延伸率、斷面收縮率、沖擊值、布氏硬度) 。
