TL;DR: In this article, the convergence of Rung-Kutta method was studied and the error between the approximate solution of Euler and Rung Kutta methods was estimated.
Abstract: We give the iterative formula of Rung-Kutta method and study the convergence.By studying the convergence of Euler method and estimating the error between the approximate solution of Euler and Rung-Kutta method,we avoid study directly the convergence of Rung-Kutta method.

TL;DR: In modern Chinese,comparative sentences are sentences whose predicates contain comparative words or comparative patterns that have their own bright characteristics of syntax and semantics.
Abstract: In modern Chinese,comparative sentences are sentences whose predicates contain comparative words or comparative patterns.The sentence structure are formed by comparative subject、comparative objective、comparative word、comparative point and comparative result.According to their semantics,they include equal comparative sentence,less comparative sentence and limited comparative sentence,all of which have their own bright characteristics of syntax and semantics.

TL;DR: In this article, rank egualities for idempotent and involutory matrices and necessary and sufficient conditions for a P+bQ bing invertible were given.
Abstract: This paper shows several rank egualities for idempotent and involutory matrices and gives several mecessary and sufficient conditions for aP+bQ bing invertible (P and Q are idempotent matrices);and gives several necessary and sufficient conditions for A+B+2I_n being invertible(A and B are involutory matrices).

TL;DR: This paper introduces advanced network simulation software-OPNET and gives an application of the OPNET in the LAN project and design too.
Abstract: People have to do a large of simulation and analyses when they design the structure and protocol of the computer and communication network system, and the network project and design, this paper introduces advanced network simulation software-OPNET. Some staple software have been compared and analyzed, the form and characteristic of OPNET、the method and the process of network simulation have been produced, and gives an application of the OPNET in the LAN project and design too.
