He most certainly deserves credit as a pioneer, with Le Verrier, of applying perturbation theory to planetary motion. 他與勒威耶都是應用微擾理論解決行星運動(dòng)問(wèn)題的開(kāi)拓者，毫無(wú)疑問(wèn)。
These additional possibilities modify the gravitational force in a small but nonnegligible way, yielding potentially observable corrections to planetary motion. 這些額外的可能性，會(huì )以一種微小但不可忽略的方式修正重力，造成的結果有可能可以在行星運動(dòng)中觀(guān)測到。
