汉英语境2
英译术语:
double sampling
汉语语境:
在地面站合理配置站上设备具有重要的实际意义。针对地面资源优化配置的两种主要评价因子提出了综合评价指标,建立了径向基函数神经网络仿真求解模型。并提出了二次抽样的思想,利用正交抽样获取样本作为径向基函数的中心,利用随机抽样选取样本测试网络。
英语语境:
It is valuable to allocate the facilities of stations properly on ground stations. According to two main evaluating factors of ground resources allocation optimization, an integrated evaluating index is proposed, and a radial basis function (RBF) neural network simulating model is established. A sampling method of double sampling is proposed, which chooses samples by using orthogonal sampling as the centers of RBF and using random sampling for testing it.
