摘要： A method and a system for register clearing in data flow analysis in decompilation are provided. The method includes: reading all function statements in a code file; sequentially judging each of the read function statements, and creating a binary tree and inputting the function statement into the binary tree in a case that the function statement includes a register name; sequentially judging each of the function statements including the register name, and performing an elimination process on the created binary tree to remove the register name from the binary tree in a case that the function statement includes a right child end tag of the binary tree, to generate a simplest binary tree; and generating a function statement in high-level language based on the simplest binary tree. All function statements can be read at a time and multiple reading and writing are avoided in the invention. In addition, a binary tree is created based on the read function statement and an elimination process is performed on the binary tree, so the function statement not including the register name can be obtained conveniently and quickly, which improves the execution efficiency.

摘要： A method for obtaining a relation between a winding state and a leakage reactance parameter of a transformer by using simulation software is provided. The method includes: establishing a simulation transformer based on a size of a physical transformer; setting parameters of the simulation transformer, setting a winding of the simulation transformer in a predetermined winding state; obtaining a predetermined number of values of a leakage reactance parameter of the simulation transformer in the winding state; and performing statistics on all the values to obtain a value range of the leakage reactance parameter in a case that the winding is in the winding state. The value range is used as a value range of a leakage reactance parameter of the physical transformer in a case that a winding of the physical transformer is in the winding state.
