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.

对于边界完全是由自由边界组成的有界区域中粘性不可压流体的非定常运动问题，Solonnikcv于1977年在忽略表面张力情况下证明了初值问题小时间解在Holder空间的存在性，于1984年在有表面张力情况下证明了初值问题问题小时间解在Sobolev空间的存在性，Mogilevskii和Solonnikov于1992年在表面张力系数可以不是常数情况下证明了初值问题小时间解在Holder空间的存在性；对于上面是自由边界、下面是固定边界且两边界在无限处趋于水平的无限区域中粘性不可压流体的非定常运动问题，Beale于1981年在忽略表面张力情况下证明了初值问题小时间解在Sobolev空间的存在性，Allain于1983年在有表面张力情况下证明了R中初值问题小时间解在Sobolev空间的存在性，但其中假定初始区域近似是个水平条，他于1987年去掉了这个假定得到同样的结果，Tani于1996年在有表面张力情况下证明了R中初值问题小时间解在Sobolev空间的存在性；对于R中内面是自由边界、外面是旋转边界S的有界区域中粘性不可压流体的非定常运动问题，Ciuperca于1995年在忽略表面张力情况下证明了初值问题小时间解在Sobolev空间的存在性，本文考虑了在有表面张力情况下初值问题可解性问题。

Exogenous E2 alone has no effect on cell viability and apoptosis of H9C2 cells, but it can decrease the sensitivity of H9C2 cells to H_2O_2,hence,protect cells against apoptosis caused by oxidative stress.2Exogenous E_2 has downregulation effect on TβRⅠand TβRⅡof H9c2 cells,blocking ER may delete this effect of estradiol.H9c2 cells express ERβonly,suggests that E_2 may exert modulating effect on TGF-βpathway through ERβ.

外源性E2本身并不能影响H9c2细胞凋亡，但能够降低H9c2细胞对H_2O_2的敏感性，保护细胞抵抗氧化应激引起的凋亡。2外源性E2对H9c2细胞的TβRⅠ以及TβRⅡ具有下调作用，阻断ER可消除E2对TβRⅠ和TβRⅡ的下调作用；E2可进一步通过TGF-β通路降低受体后磷酸化smad2/3的水平；H9c2细胞仅表达ERβ，提示E2可能是通过ERβ发挥其对TGF-β通路的调控作用。

Results After the therapy, the sTfR and erythron increased significantly, but bone marrow iron deposits decreased progressively as HCT increased. The sTfR had a apositive correlation with RBC (r=0.632, P.01) and positive correlation with Hct (r=0.757, P.01) and positive correlation with E%(r=0.775, P.01). No correlations were observed among sTfR and other parameters.

If R admits a generalized derivation δ with d=0 such that either δ=x°y or δ+x°y=0 holds for all x,y∈I,and if δ is not the identity map,then R is commutative.

设R是素环，I是R的非零理想，如果R容许一个非单位映射的左乘子使得对所有x，y∈I满足δ=x°y或δ+x°y=0，那么R可交换。
