<正> The Newtonian inverse square law of gravitation has been accepted as correct in the static, weak-field limit at all distances. However, it hass been pointed out recently by some authors that the law has been well examined only at celestial distances,and the existing experimental data cannot exclude a possibility that the Newton’s law may be violated at distances less than 10~3 km. In other words, the gravitational 'constant' G is probably not a constant at such distances but a function of the separationr. Long has suggested that the function at laboratory distances should take the
