误差带 meaning in Chinese

error band

As i have indicated , there are weak solutions at present for large space - time windows
如我表示的那样，在较大的空间?时间误差带条件下目前有一些较薄弱的解决方案。
How the parameters of above two helixes affect their shapes is discussed . furthermore , error analysis and distribution are given . any prescribed precision can be arrived by the approximated helixes
方法二，增加重合点，使理论螺线和逼近螺线在五点处重合，从而反求出控制顶点，使误差带更窄。
