This research concentrates on the optimal factor selection of this modification with Kolmogorov test. The factor is a constant for all tolerance. This optimization method can bring a significant reduction of the difference between variation analysis and tolerance analysis. The thesis presents a framework to model and evaluate assemblies and their assembly process for autobody structure concept design. This framework makes the autobody structure concept design more science-based than experience based, and will significantly enhance the dimensional quality of autobody assemblies.

Namely, the first, the beginning, end and length of growing season of every type of vegetation is estimated with threshold method and moving average method, and the beginning end and length of growing season of vegetation from 1982 to 1999 is fitted linearly, finally, linear trend of the beginning end and length of growing season of vegetation is analyzed. The second, phenological phase in different years and zones is estimated based on greatest changes of slope method and EOF analysis method, and the result monitored by the two methods is compared, as a result, trend of growing season change from 1982 to 1999 in different latitude zones is better acquired. The third, phenological phase of vegetation in different spatial location from 1982 to 1999 is fitted based on curve. Then, spatial difference rules of growing season of every year and average of multi-year is discussed in article. In the end, lag correlation and linear regress are used to study relation between phenological phase of different types of vegetation, different latitude zones, different spatial places and climate changes.
