Large eddy simulation ( les ) , as a newly developed method for turbulent airflow simulation , has not only the advantage of smaller calculation effort but also achieve very high accuracy in most cases . at the same time the solution reserves the random characters of the flow field , which fits better with actual measurement than rans does , and therefore , les is showing its great superiority and powerful vitality 大涡模拟( les )作为一种新兴的湍流运动数值仿真工具,不但计算量小于直接模拟且很多情况下达到了很高的精度要求,同时还保持了流动的随机性特点,比rans预测结果更加符合实际情况,所以正显现出巨大的优越性和强大的生命力。
So the framework chanmical way was adapted to study the character of the pipelines ' response under trigonometric function traffic loads ; then the randomicity of the parameters were taken into account , the paper uses the perturbation theory to describe the random character about the changing parameters of the pipelines . the calculate formula and simply resolution of response character of pipelines under random loads was educed . the technique of numerical value can stimulate the complex actual situation effectively 应用数值技术可以有效的进行实际复杂情况的模拟,因此,文中对管道在恒定交通荷载和简谐荷载下管道的纵向以及横向受力特性进行了数值模拟计算,主要采用比较适合于土体计算的abaq二软件进行,同时也对其各影响因素作了相关敏感性分析。
This paper analyses crystal oscillator ’ s character and technique targets , and the changes of these technique targets effect the time of crystal oscillator gives the error mode of crystal oscillator time , by discussing gps system and time service theory , we analyze random character of gps second pulse error . we combine long - time stability of receiver ’ s output signal and short - term stability 该系统成功地应用于宽频带地震记录仪中,使地震数据记录的时基精度达到微秒级,可以解决大范围的地震仪布设应用时的授时和空间定位(经度、纬度、海拔)问题,为地震数据记录、分析工作提供了与国际标准时间同步的时间基准。
