The main findings were as follows: 1. The results revealed that the conjunction of agreement and inconsistency among family members was found in a family. The phenomenon showed that in " the sameness has the differentness" and between "the differentness has the sameness", and it is the special result of system measurement. 2. It proved the system theory including "one adding one are not two", existence of subsystems. 3. Every family member has different perception to the same dyad relationship, so the subject should use the units of whole family, including father, mother, and one child or more. 4. The same members of this family had different perception to different dyad relationship, so the content of instrument should include different dyad. 5. In regard to analyzable methods of family system, the variance is between family members, and it is not adaptation to using average method and variance method.

Then, the relation between vibration and sound, the acoustic holography method, the indeterminacy and identifiability of BSS, the BSS algorithm are discussed in detail. Based on above researches, the dissertation is divided in following four sections. The first section investigates the BSS algorithm suitable to acoustic feature separation. The algorithm of the joint approximate diagonalization of eigen-matrices is proposed. The spectra or the time-frequency distributions of source signals are the interesting features in ABD and they are separated from mixing signals by JADE algorithm. Then, the convolutive mixing model is transformed into a high-dimension instantaneous mixing model, and the deconvolution of source signals is achieved by the joint approximate block diagonalization of eigen-matrices. The proposed algorithm has a global minimum, and it is unsensitive to noise interference.
