This interpolation module uses the popular and advanced nurbs interpolation technology . the procedures of math processing for nurbs , preprocessing for interpolation and real - time interpolating running on dsp are presented in this article . the interpolating procedure uses an advanced self - adjusting interpolation method , which can automatically adjust the length of interpolation according to machining speed , acceleration and the tolerance of bow height 插补模块则采用了当今最流行最先进的nurbs插补技术，设计了nurbs数学处理程序，插补预处理程序，运行于dsp的实时插补程序，该插补软件采用了先进的自适应插补方法，可以根据加工的速度，加速度，弓高误差的要求自适应调整插补步长，同时采用了对插补点的预估算法，免去以往加工方法中求导的运算，大大降低了运算量，提高了加工速度。
The main idea under controller design is damping model nonlmearities with control input to force the system dynamic into a linear sliding surface and utilizing dynamic filters to ensure the boundedness of states , inputs and outputs . the mismatched model uncertainties are suppressed with extra items in control input Dsc控制器通过对消系统非线性项，将系统动态驱至线性滑模态；引入动态滤波器，确保系统的状态及输入输出有界，同时避免了对非线性模型多次求导带来的复杂性；在虚拟控制输入中利用附加项来克服不满足匹配条件的不确定性。
According to the types of rock density and magnetism of magmatite , with separation , continuation , derivation , and false color encoding between gravity anomaly and magnetic anomaly as well as a composite process of their attributive information , the magmatite belts reflected by both gravity anomaly and magnetic anomaly can be divided into two belts and seven group sections based on their positions in the tectonic unit , the magma series characteristics , and the time - space relationship with the ore belt 摘要根据不同类型岩浆岩的岩石密度、磁性的不同，通过重磁异常分离、延拓、求导、异常的彩色编码及重、磁特徵信息的复合处理等，按重磁反映的岩浆岩带所处的构造单元部位、岩浆系列特徵以及与矿带的时空关系，将秦岭造山带划分为2带和7个群段。
To apply the load derivation method to short - term load forecasting , which is usually used in ultra - short term load forecasting for its high precision and reliability , the strategies adopted in the method . such as difference operation , reducing forecasting value and using " near large and far small " and " similar day " characteristics , are analyzed in this paper 摘要为了将超短期负荷预测中具有高准确率和高可靠性的负荷求导法移植到短期负荷预测中，从采用差分运算、降低直接预测的数值，以及充分使用负荷“近大远小” 、 “相似日” ，性质等角度对其进行了分析。
In regard to the former , this paper proposes that we could express the displacement function of the member with the b - spline theory , calculate its differential coefficient and express it into the moments and shears of the sections , then set up equations and solve them to get the displacement function 在分析厚板转换层在水平荷载下的内力时，将实体墙、框架等构件的位移函数用b样条来表示，然后对位移函数求导，表示成截面的弯矩、剪力，进而建立静力平衡方程，求解方程得到位移函数。
