PVM/MPI并行编程方法是目前编程人员广泛使用的方法之一,但此方法将并行性开发的任务完全交给编程人员,由于系统开发方法的缺乏以及编程人员水平与风格的差异,软件的质量与效率往往难以得到保证。为此,本文在PVM/MPI并行编程方法研究的... PVM/MPI并行编程方法是目前编程人员广泛使用的方法之一,但此方法将并行性开发的任务完全交给编程人员,由于系统开发方法的缺乏以及编程人员水平与风格的差异,软件的质量与效率往往难以得到保证。为此,本文在PVM/MPI并行编程方法研究的基础上,引入了设计模式的思想,并针对一种典型的并行程序风范———“管理者-工人”设计模式的思想进行了定义、描述与实现。编程人员通过使用本文实现的设计模式,极大地减轻编程负担,有效地提高并行程序的可编程性,有利于在解决可适用管理者-工人并行程序风范的一类问题时得到结构良好的并行程序。 展开更多

Objective: To understand the situation of nursing students was stabbed by sharp instrument,in order to provide a scientific basis to take protective measures.Method:By using a self-designed questionnaire.The 100 nursing students were randomly selected from a hospital for retrospective investigation.There are 98 valid data.Results: The data shows that sharp instrument injury is more common in nursing students. Nursing students' protection consciousness is low, and protective ability is poor.Conclusion: Nursing students awareness of self- protection to sharp instrument injury is not enough,in order to avoid the risk of infection of nursing students occupation.When they entered the clinics, practice of systematic pre occupation safety education is very necessary;and the school and the hospital should actively implement the management standardized operation regulations;and put up student occupation injury management regulations;to improve the safety performance of nursing equipment. 展开更多
