| 2. | The projection index values were gave by multiplying projection vector by standardization value of evaluation indexes , which can comprehensively evaluate agricultural resources use efficiency of every unit
通过最佳投影方向与评价指标的线性投影得到投影指标值，通过这一指标可以对样本进行统一评价。 |
| 3. | The surface detail or offsets simulated by a normal map are always relative to either the polygon it ' s projected on ( tangent space ) or the object ' s orientation ( object space ) or the world ( world space )
（通过法线贴图计算出的表面细节和偏移是总是相对于多边形的投影方向或是物体的自身轴向（物体空间）或是世界（世界空间）的。 ） |
| 4. | Pcc takes the normal vector of a hyperplane as the projecting direction , onto which the algebraic sum of all samples " projections is maximized , such that samples in one class can be separated well from the other by this hyperplane
主分量分类器是在两类样本投影代数和最大的前提下，获得最佳投影方向(分类面法方向) ，实现样本分类。它的不足之处在于： 1 |
| 5. | Project pursuit can be used to project high dimensional data to low dimensional space and find the optimum projection vector of data in one dimension space by data character of research units , which can comprehensively evaluate the value and direction of every index
该方法可以依据样本自身的数据特性寻求最佳投影方向，从而判断各评价指标对综合评价目标的贡献大小和方向。 |
| 6. | By the reason of characteristic on statistics of images , we gave a face searching and locating algorithm based on the second derivatives operator . we obtain the position of face by calculating the change of projection curve using the second operator
该方法计算人脸在两个投影方向上的统计特征，使用二阶微商算子估计投影曲线斜率的变化，进而找出人脸的外接矩形，判断头部在图象中的位置。 |
| 7. | It redefines the between - class scatter by adding a weight function according to the between - class distance . therefore , it can separate the classes as much as possible . at the same time , it projects the between - class scatter into the null space of the within - class scatter that contains the most discriminant information
新方法重新定义了样本类间离散度矩阵，在原始定义的基础上增加一个由类间距离决定的可变权函数，使得在选择投影方向时，能够更好地分开各个类的样本。 |
| 8. | In the aero - optical flow field tomography measurements , all projection data of different direction must be simultaneous . and the laser nozzle flow field up - stream and down - stream strehl ratio simultaneous measurements have the synchronicity requirement . the working environment of high power laser is rigorous and complicated
在考虑了由于气动光学流场层析测量中的多个投影方向数据的同时测量、激光器喷管流场上游和下游同时测量的同步要求,以及高能激光平台的复杂环境多方面因素的基础上,考虑了硬件匹配的一些问题,设计了一套高速的线阵s - h传感器。 |
| 9. | Since the cause of caustics phenomena is that the tangent plane of lagrange submanifold in caustic fields is perpendicular to the original physical space , we solve the high frequency asymptotic problem in a new mixed space by changing the projecting direction , then we get the high frequency asymptotic solutions of wave equations efficiently near and on the caustics
由于出现焦散现象的原因在于lagrange子流形在该处的切平面与物理空间垂直，通过转换适当的投影方向，然后将这个投影方向上得到的高频近似解再变换回到原来的物理空间中，得到了在焦散附近适用的高频近似解。 |
