Embodiment Construction
[0039] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:
[0040] A calculation method for constructing a gravitational gradient field of a complex shape is realized based on the following principles:
[0041] The interaction force between two stationary point charges in vacuum satisfies Coulomb's law, that is, it is proportional to the product of its charge quantity and inversely proportional to the square of its distance, and the direction of the force is on the connecting line between the two. Mutual repulsion, different names attract each other, the expression of the gravitational field between objects is:
[0042]
[0043] In the formula, r is the distance between the two, q 1 ,q 2 is the charge quantity of two point charges, e r for from q 1 to q 2 The radial direction of the direction, k=9×10 9 N m 2 / C 2 is Coulomb's constant. This formula is in the same form as the expression of univer...
