On the basis of intrapair and interpair correlation model, we have calculated the pair correlation energies of different kinds of systems, analyzed the changing rules of correlation energies of various electron pairs, and developed a reasonable and simple scheme called "Separating Large System into Smaller Ones". The basic idea of this scheme is that the correlation energy contributions of actual components in the ionic compound can be obtained using the correlation energy of ions with integer charge as the boundary conditions and incorporating the HF wave function or the distribution of electron cloud, then the total correlation energy of the system can be estimated by linearly summarizing the correlation contributions of these components.

Chapter 5 and 6 are concentrated on the fundamental problem how to con-struct finite-dimensional and infinite-dimensional Liouville integrable Hamiltonsystem.Starting from two isospectral problems,Tu's scheme is applied to gen-erate the corresponding CKdV hierarohy and coupled Burgers hievachy,andthey are shown to be Liouville integrable Hamilton systems.Two spectral prob-lems,which contain three and four potentials respectively,are also studied byTu's scheme.Two new Liouville integrable Hamilton hierarchy are estab-lished.A new general approach using Lenard's gradient sequence is presentedto obtain Lax integrable hierarchy and their zero curvature representation,andsome examples are given.The nonlinearization procedure is applied to theeigenvalue problem of coupled Burgerrs hierarchy.It is shown that underBargmann constraint,the spatial part of the Lax pairs is nonlimearized to be afinite-dimensional Liouville completeiy integrable Hamilton system.

The mean generation interval of the flock is 5. 42 years of the current breeding scheme, and the ratio of input and output is 1∶11. 50, but the rate of mammitis will increase at the speed of 2%, at the same time, the number of daughters and sons of test bulls is not large enough for good accuracy for estimating test bull breeding value, so the breeding scheme in effect need to be improve.

D、在影响育种效益的诸因素中，单一的加大群体规模、育种群比例以及每年选留测验公牛数将在一定程度上提高育种效益和遗传进展，但随选留种子公牛数提高将降低育种效益和综合育种值遗传进展；在育种实践中应尽量扩大育种群规模和主动育种群比例。
