摘      要：Studies of the amniotic pressure developed during uterine contraction have been largely empirical. A recently proposed model of uterine contraction, however, has successfully described the development of this pressure in terms of a contraction wave propagating over the surface of the uterus and of basic myometrial properties. Qualitative and quantitative agreement have been found. This model is now extended to the relaxation phase of the uterine contraction cycle. The cases of complete myometrial relaxation and of partial contraction and partial relaxation are considered. As a result, a quantitative description of the complete contraction phenomenon is given. A semi-logarithmic representation of the relaxation phase pressure is suggested as being more revealing and more sensitive to details of uterine behavior. Agreement between the model and experimental measurements is good. The quantitative disparities are discussed in terms of observed behavioral variations.
