The paper research on durability of reinforced concrete structures on basis of reliability theory and draw a conclusion : durability design coefficient is function of reliability index random process 本文从可靠性基本理论出发,得出耐久性设计系数是可靠度指标下降过程的函数;按照耐久性设计系数对结构进行耐久性分析、设计与评估。
The paper analyzes and studies the reasonable amount of water regulation of the project under the interaction of multi random process by taking huayuankou station of the main yellow river as an example and using serial operation theory 以黄河干流花园口站为例,应用序列运算理论,分析研究了在多随机过程相互作用下,南水北调西线工程合理调水量。
One target to study the network performance is to find out the mathematical expressions between each measure . probability , random process and queuing theory are important and useful mathematical tools for network analysis 求出反映定量指标间关系的数学表达式是研究网络性能的目标之一,而概率论、随机过程和排队论是进行网络性能分析的重要数学工具。
The two - dimensional statistical model of terrain is described by planar non - stationary random process and function w - m in topography . on the basis of the statistical model of terrain , the simulated digital maps are produced by computer 对仿真中用到的二维随机过程和分形学中的w - m函数产生地形数学模型的方法做了讨论,采用二维随机过程的方法产生了数字仿真地图。
It is necessary to study the reliability of the structure during the construction because the structure is a time - varying system and the variable loads are random processes about time with particular characteristics different with the use period 由于施工过程中,结构是一个时变结构,结构的抗力是一个随机过程,荷载也具有与使用期不同的特点,所以有必要研究施工期间结构的可靠度。
