By using degenerated - hysteresis model to represent the nonlinear hysteretic restoring - force character of the laminated rubber isolation bearings , isolating affection of base - isolation building are studied 摘要采用退化迟滞模型模拟叠层橡胶隔震支座的非线形滞回恢复力特性,对基础隔震结构的隔震效果进行了研究。
The groundwater exploitable resource in draught year is 10951 104m3 . the results can be used to instruct the actual exploitation and make the sustainable utilization of the groundwater source true 模型模拟的不同特征年时地下水库的允许开采量,对指导合理用水,实现地下水资源的可持续开发利用具有现实意义。
We then specify where the observer s eye will be located . the ray tracing program will mathematically model the objects , the light rays and the observer and compute the colour for each pixel on the screen 光线追踪的程式会利用数学模型模拟物件光线及观察者之间的关系,从而计算观察者在电脑屏幕上应看到的影像。
Abstract : a dispersion test is carried out in field in order to get the dispersion parameters of the shallow aquifer . fem model is used to simulate the dispersion process in the test area 文摘:通过现场弥散试验测定浅层含水层的水动力弥散参数,用有限分析法模型模拟弥散试验场,为建立滨州市浅层地下水溶质运移模型提供依据。
It may sound like the latest fantasy adventure game or a new indiana jones movie , but it happens to be what scientists discovered in 1995 with a sophisticated computer model of earth ' s inner core 它听起来像最近的幻想冒险比赛或新的印地安那州琼斯电影,但是这正好是科学家在1995年以地球内部中心复杂的计算机模型模拟发现的。
