Firstly, a probe into the dual implications of burden of proof and the expurgation of its intrinsic meaning and result meaning is burden of proof in applied conditions of burden of proof .We should make a definition of applied conditions of burden of proof .The thesis makes a research into the internal structure of applied conditions of burden of proof so as to clearly show the triple contents of its internal structure. In addition, the thesis makes a probe into its regulating mechanism. It points out clearly that applied conditions of burden of proof must ensure the correct application and cautious application of burden of proof.

The differentiation states of costae indicates the ways they absorb and transport water, and their ability adapting to the dry conditions, which was elucidated by the following examples: Brachythecium plumosum, because of its thin cell-walls in the costae and the absence of hydrome, assistant and steroid cells, can absorb water and nutrition under shady and moist conditions; Plagiomnium rostratum, though often grows in shady and wet condition, has hydrome and steroid cells, a feature similar to those of xeric mosses, which endows it to grow in the conditions with periodical drought stress during its life cycle; Hygrohypnum luridum is characterized by its slender leaves with only one layer of cells, the thin cell-walls, the absence of filaments on the leaf surface, and the fewer layer cells in the costae, the absence of hydrome and steroid cells. These features make it adaptable to aquatic environments. For Pogonatum inflexum and Atrichum undulatum, their ventral surfaces covered with lamella, while for Racomitrium japonicum, Thuidium cymbifolium, Macromitrium ferriei, Diphyscium fulvifolium, Barbula unguiculata and Ceratodon purpureus, their leaves are strongly mammillose or papillos. Such appendiculate structures made them adaptable to thy conditions.

Significant effects of warming onbiomass allocation were only found for the A. faxoniana seedlings grown under lowlight conditions, with significantly increased in leaf mass ratio and decreasedin R/S in responses to warming manipulation. The carbon allocation responses of B.albo-sinensis seedling to warming under full light conditions were similar with theresponse of A. faxoniana seedlings grown under low light conditions. Warmingsignificantly decreased root mass ratio, and increased leaf mass ratioand shoot/root biomass ratio for the B. albo-sinensis seedlings grown under fulllight conditions.

无论在全光或林下低光环境下，增温都促使云杉幼苗将更多的生物量分配到植物地下部分，从而导致幼苗在增温条件下有更高的R／S比；增温仅在林下低光条件下促使冷杉幼苗将更多的生物量投入到植物叶部，从而使幼苗R／S比显著地降低：增温在全光条件下对红桦幼苗生物量分配的影响趋势与冷杉幼苗在低光条件下相似，即增温在全光条件下促使红桦幼苗分配更多的生物量到植物同化部分一叶部。

Under weaker conditions(without theirhomogeneous conditions,monotonic inequalities and Lipschitz conditions)than that which Iwaniec and other people imposed on some specialsystems(quasi-regular mappings),using Hodge decomposition theoremto construct testing function,after a series of complicated calculation,weobtain the same regularity results as them to a more general non-linearelliptic systems(2):under certain conditions,the very weak solutionsto non-linear elliptic systems(2)are weak solutions.
