关键词： Banach空间   （H，η）-增生算子   新变分包含组问题   数学分析  

摘要： In this paper,we first introduce a new class of generalized accretive operators named(H,η)-accretive in Banach *** studying the properties of(H,η)-accretive,we extend the concept of resolvent operators associated with m-accretive operators to the new(H,η)-accretive *** terms of the new resolvent operator technique,we prove the existence and uniqueness of solutions for this new system of variational *** also construct a new algorithm for approximating the solution of this system and discuss the convergence of the sequence of iterates generated by the algorithm.

摘要： In this paper,let T be a bounded linear operator on a complex Hilbert *** give and prove that every p-w-hyponormal operator has Bishop's property(β)and spectral properties;Quasi-similar p-w-hyponormal operators have equal spectra and equal essential ***,for p-w-hyponormal operators,we give a kind of proof of its normality by use of properties of partial isometry.

关键词： Reliability analysis  

摘要： In electrified railway traction power supply systems, the operational qualities and reliabilities of the main traction transformer loop is higher, but ones of bus output units is comparatively low. The traction transformer loop still works when output loops are in failure, and the output loop interrupts working when the main transformer is in failure, and only has residual life when restoring working, the connection formation between them is in series. Traditional reliability analysis methods let their lifetime follow exponential distribution, and reliability is investigated based on the minimal path sets, which lead to a comparatively rough result, consequently. According to Markov theory, in this paper the main loop life is considered as mixed Erlang distribution with order n, and the output unit life follows generic distribution. As compared with conventional series systems, the acquired results are proved to be reliable and sound.

关键词： 数学化   自由落体运动   数学分析  

摘要： 有一句著名的格言:数学比科学大得多,因为它是科学的语言。首次提出这种见解者是大约400年前伟大的自然科学家伽利略。他是世界上第一个使用数学语言:v=32(t这里32表示32英尺,相当于9.76米,已和重力加速度g的值接近)来表述自由落体运动,

摘要： In this work,the well-known problem put forward by S N Bernstein in 1930 is studied in a deep *** operator is constructed by revising double interpolation *** is proved that the operator converges to arbitrary continuous functions uniformly and the convergence order is the best.
