There are series of papers studying the solvability of an incompressible, viscous, instationary fluid contained in a domian bounded entirely by a free surface. In 1977, Solonnikov proved its local solvability in a Holder space for any initial date but without surface tension. In 1984, he considered the same problem in a Sobolev space with surface tension being taken into account. In I992, Mogilevskii and Solonnikov treated the same problem in a Holder space, where the coefficient of surface tension is not a constant. There are also short-time existence results for the solvability of an incompressible, vicous, unsteady fluid bounded above by a free surface and below by a fixed bottom which approach horizontal planes at infinity. In 1981, Beale proved its local solvability in a Sobolev space for any initial date but without surface tension. In 1983, Allain were concerned with the same problem in R〓 with surface tension but under the assumption that the initial fluid domain was near a horizontal strip. In 1987, he obtained the same result without the preceding assumption. In 1996, Tani solved the same problem in R with surface tension. For the solvability of an incompressible viscous instationary fluid in Ω R bounded inside by a free surface S and outside by a rotating boundary S, in 1995 Ciuperca proved its local existence in a Sobolev space for any initial date but without surface tension. In this paper, we consider the same problem with surface tension.

The amount of Ca8-P in soil with CRMP treatments was lower than that of CMP treatments. The changes of the amount of Al-P, O-P, Fe-P and Ca10-P in soil were neglectable during the course of experiment.3. The shoot and root weight of sorghum increased through application of phosphorus, in addition, The increase of sorghum shoot and root weight was greater than that of common monoammonium phosphate due to the slow release of nutrients from CRMP. The accumulative uptake of phosphorus in shoot and root with CRMP treatment was greater than that with CMP treatment in low (75 mg P2O5/kg soil ) and high(150mg P2O5/kg soil)rates, especially on middle stage, and in high phosphorus rate, this advantage was more obvious than that in low phosphorus rate.
磷肥的施入,促进了高粱地上部和根部的生长,而控释肥由于缓慢释放养分,与作物吸收相一致,更能促进高粱的地上部和根部干物质积累;对于高粱地上部及根部的磷素累积,在两种施磷水平下控释处理地上部及根部磷素累积量均大于非控释处理,尤其是在中期,而且高磷水平下优势更加明显,低磷控释处理的磷素累积量能达到高磷非控释的累积量,即减少一半的用量即能达到同样的效果;在氮、钾、钙、镁相同的水平下,控释处理比非控释处理更能促进地上部及根部氮、钾、钙、镁累积量,这种优势在中期表现最明显。4。

There were no significant facilitating effects to the retention of signaled information in the overuse of text signals condition, but there were in the selective use of text signals condition. Experiment 3, in which 2 small experiments contained, studied the effects of reader-based factors. Experiment 3a examined the effects of the familarity to the text topics and the readers' reading levels. Experiment 3b explored the effects of cognitive style and the intention to use the text signals. The results were as the follows: There were no significant difference between the signaled and unsignaled conditions in the circumstance of high familarity to the text topics, but there were significant differences between them in the circumstances of lower familarity to the text topics. There were no significant differences between the signaled and unsignaled conditions for the field-independent participants, but there were for the field-dependent participants. All the participants with different reading levels were helped by the text signals.
