ASM also provides an error correction formula deduced from matrix inversion theorem to clear up the error originated from approximate synchronous sampling.

近似同步法还提供了一个用基于系统辨识的矩阵反演定理导出的误差校正公式，它能消除近似同步采样造成的原始误差。

And during the inversion, two constrained models, flattest and smoothest model, were incorporated into the sensitivity matrix calculated by theoretical formula.

在反演过程中，根据理论公式计算迭代过程中灵敏度矩阵，并采用平坦模型和光滑模型两种约束。
