说明：  The intention of Ackermann geometry is to avoid the need for tyres to slip sideways when following the path around a curve. The geometrical solution to this is for all wheels to have their axles arranged as radii of circles with a common centre point. As the rear wheels are fixed, this centre point must be on a line extended from the rear axle.

共轭梯度法（Conjugate Gradient）是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一。 在各种优化算法中，共轭梯度法是非常重要的一种。其优点是所需存储量小，具有步收敛性，稳定性高，而且不需要任何外来参数。(The Conjugate Gradient method is a method between the steepest descent method and the Newton method. It only needs to use the first derivative information, but overcomes the shortcoming of the steepest descent method and avoids the need for the Newton method to store. And the disadvantage of calculating the Hesse matrix and inverting, the conjugate gradient method is not only one of the most useful methods for solving large linear equations, but also one of the most effective algorithms for solving large-scale nonlinear optimization. Among various optimization algorithms, the conjugate gradient method is a very important one. The advantage is that the required amount of storage is small, step convergence, high stability, and no external parameters are required.)

对海量图像进行分块索引，可以不限数据量大小对图像进行漫游。 使用办法，首先选择图像处理中导出索引这一功能，将海量的BMP图像格式转换为自定义的img格式，再在打开菜单中打开IMG格式的影像，就可以完成对海量数据的浏览，数据量不受内存限制，只受硬盘大小限制，另外该软件还包括其他一些图像格式之间的转换，主要用在GIS领域-Images of the mass block index, you can open the volume of data roaming size image. Use practices, the first choice of image processing to export the index of this function, will be massive conversion of the BMP image format for custom img format, and then open the menu opens in IMG format images, you can complete the huge amount of data browsing, data not subject to memory limitations, only by hard drive size limit, while the software also includes a number of other conversion between image formats, mainly used in the field of GIS
