在第一章，我们应用上、下解方法，bootstrap技巧和Schauder不动点定理考察如下三类周期反应扩散方程组的周期稳态解的存在性和一般的时变解的渐近性态：（1）拟单增系统；（2）混拟单调系统；（3）一个非拟单调2-系统，其边界条件是Dirichlet条件或线性Robin条件。

In Chapter 1, we use the upper and lower solutions method, the bootstrap technique and the Schauder fixed point theorem to investigate the existence of periodic solutions and the asymptotic behavior of general time-dependent solutions for periodic reaction-diffusion systems of the following three types:(1) Quasimonotone nondecreasing system;(2) Mixed quasimonotone system;(3) A nonquasimonotone 2-system. The boundary conditions are assumed to be either the Dirichlet condition or linear Robin conditions.

Results (1) The complex of cells and scoffolds suspended in themedium at first, sunk at the bottom of medium after 2 days. Some cellsmay overglow scoffolds, but the tenacity was increased and the surfacewas lenitive in the induced groups.(2) Scanning electron microscopeshowed many spherical cells distributed in pores and on the surface of thescaffolds.

This implies a major stage of crustal growth in Proterozoic time and remelting of the crustal material in Early Jurassic time;(5) The Oligocene-Miocene adakites contain magmatic zircons that show similar Hf isotope compositions to the Cretaceous-Paleogene Gangdese batholiths, providing a key constraint that allows evaluation of the nature and timing of crustal thickening in southern Tibet owing to the India-Asia collision; and (6) As a whole, the Hf isotope information observed in zircons from the above Transhimalayan rocks demonstrates a temporal variation in εHf values, and thus TDMC ages, that suggests multiple stages of orogenic or crustal formation events.
