determinate system meaning in English

确定体系
确定组

However there are some signals different from the two poles , named chaotic signals , which are generated by a determinate system but acting similar to stochastic signal and can not be forecasted in long term
而混沌信号有别于这两大类信号，它由确定性系统产生，但行为却貌似随机信号，具有长期不可预测性。
Many investigations show that randomicity of structures ? parameter will bring large value of stochastic dynamic response of structures . randomicity of structures ? mechanics parameter may be dominant factors . therefore , introduction of randomicity into system model of structure and using random system model are more reasonable than that of determinate system model
众多的研究工作表明，结构参数的随机变异性可以引起结构随机动力响应的大幅度涨落，结构力学参数的随机性还可能成为主导因素，在结构系统模型中引入随机性的概念，采用随机结构系统模型是较确定性结构系统模型更为合理的一种选择。
