英文摘要：

This paper employed the tangent linear model and the strategy of source-to-source transformation, developed differentiation transforming system in C （DTC） to calculate the Jacobian-vector product in the solution of nonlinear equations with Newton method. Then introduced the calculation model, functionality, and discussed features of the system, and the techniques of design and implementation of the system, including compiler technology, differential code transformation, and input/ output （I/O） dependence analysis. Last presented some persuasive testing and applications.
