In order to cultivate the ability to think in space in the teaching of sketch,it is necessary to have a good mastery of the shape of geometry constituted by points and lines at the beginning state of realistic sketch,This is the basic medium and method in embodying precisely the sense of depth and volume of three-dimensional space in the two-dimensional level.
在素描教学中要培养空间思维能力,应该在写实素描的起步阶段,把握住点线构成的几何形组合,这是在二维平面上准确体现三维空间深度感、体积感的最基本的介体和手段,能为进一步客观、准确、深入地塑造和表现对象打下纯视觉形体框架的基础。
The previous methods have disadvantages in which of geometry-free linear combination and Melbourne-Wu bbena linear combination for detecting cycle slips in GPS carrier phase.
指出了以往使用无几何距离组合联合MW组合探测GPS载波相位周跳的不足之处,提出3个改进的措施:(1)使用双低通滤波器平滑伪距;(2)利用周跳在高阶差分中的时间序列特征,使用最小二乘法定位和估算周跳;(3)对解算得到的周跳浮点解进行条件搜索,得到周跳的整数解。
