Lastly,we present an algorithm to isolate real roots of a univariate spline, i.e., computing asequence of disjoint intervals such that each of them contains exactly one real root of agiven spline function, which is primarily based on the use of Descartes rule of signs withits B-spline coefficients and de Casteljau algorithm of Bzier curve.

为了更好地进行干涉判断，根据椭圆-椭圆外切的代数条件——广义特征多项式具有正的重根，以及进一步证明出的该正重根的唯一性结论，利用仿射变换和逆变换方法，推导出了椭圆-椭圆的不适合边界解析方程。

Lagrange interpolation focus on the application of the formula .The comparison between the method of Transform and that of Lagrange's interpolation formula in square matrix form is made. Also the form of Lagrange's interpolation formula is generalized to include the double root case.The application of the generalized lagrange's interpolation formula in square matrix to solving state equations is found to be effective.

重点介绍了Lagrange插值公式在状态方程求解中的应用，用对角矩阵及相似矩阵的性质证明了，当状态转移矩阵中方阵的特征根相异时，拉格朗日插值公式与Laplace变换法对表达具有一致性，并用极限方法对方阵含二重根时拉格朗日插值公式的应用进行了推导。

The analysis of the chemical constitutes among sterns roots and leaves of Dracaena cochinchinenis, showed that there' s small amount loureirin A in their extracts, with 0.053mg/g, 0.058mg/g, 0.015mg/g respectively only. Therefore, the roots, stems and leaves of Dracaena cochinchinenis have too low contents of loureirins to be raw materials of dragon's blood.

分析剑叶龙血树根、茎、叶的成分，发现风干的剑叶龙血树根、茎、叶中没有龙血素B的存在，只含有少量的龙血素A，其含量在根、茎、叶中分别为：0.058mg/g，0.053mg/g，0.015mg/g，其含量远低于现行的龙血竭中龙血素A含量不低于2％的质检标准，因此剑叶龙血树的根、茎、叶不能直接用作生产龙血竭的原料。
