| 6. | Stylistically , the ibm mainframe roots of rexx show in its case - insensitive commands ; and to a lesser degree in the relative sparsity of punctuation it uses preferring keywords to symbols
在文体上， rexx的ibm / mainframe根源体现在它对命令的大小写敏感；在某种次要程度上也体现在它使用标点符号相对较少（更多用关键字而不是符号） 。 |
| 7. | This one is complicated than the former . by using sparsity matrix technique and recursion , it can also be used in the larger system . the simulation system is constituted with matlab and the programs are formed with c language
前者算法结构简单，便于编程实现，且计算速度快，主要适用于规模较小的系统；后者算法结构较前者复杂，程序实现困难，但由于采用了稀疏矩阵技术，并用递推法修正因子表，所以可以应用于规模较大的系统。 |

| 9. | Sad is able to differentiate models in form of subroutines , fully exploit the sparsity of the models and need few additional operations . it is concluded that sad is very suitable for the process models that have relatively simple computational structure and consist mainly of polynomials
符号自动微分具有可对子程序形式的函数求导、可以充分利用模型的稀疏性、无需辅助操作的优点，非常适合针对结构相对简单、计算式以多项式为主的过程系统模型求导。 |
| 10. | This paper applies generalized multipler method to translate convex quadratic programs with equal constraints and non - negative constraints into simple convex quadratic programs with non - negative constraints . the new algorithm is gotten by solving the simple quadratic program . it avoids the computation of inverse matrix and exploits sparsity structure in the matrix of the quadratic form . the results of numerical experiments show the effectiveness of the algorithm on large scale problems
根据广义乘子法的思想，将具有等式约束和非负约束的凸二次规划问题转化为只有非负约束的简单凸二次规划，通过解简单凸二次规划来得到解等式约束和非负约束的凸二次规划新算法，新算法不用求逆矩阵，这样可充分保持矩阵的稀疏性，用来解大规模稀疏问题.数值结果表明：在微机486 / 33上就能解较大规模的凸二次规划 |
