The influence of free surface on tunnels is discussed.The influence of blasting vibration on fresh concrete lining is studied. The finite element method is employed to analyze the spatial distribution of temperature and thermal stress of fresh concrete lining, the wave function expansion method is used to study the interaction of blasting seismic wave and the circular tunnel with lining, thenthe safe PPV of fresh concrete lining with different age is decided by taking into account the thermal stress of concrete lining. Using the conformal mapping method, the influence of blasting vibration on the arch tunnel with lining is studied and the safe PPV of concrete lining is deduced under different incident angle.

研究了爆破振动对新浇混凝土衬砌的影响，采用有限元法求出了圆形洞室新浇混凝土衬砌内温度和温度应力在空间上的分布及其随时间的变化，采用波函数展开法求解了爆破地震波与有衬砌圆形洞室的相互作用，获得了考虑新浇混凝土衬砌内温度应力前提下不同龄期的新浇混凝土衬砌的安全振速；利用保角变换研究了爆破振动对直墙拱形有衬砌隧洞的影响，得到了爆破地震波以不同角度入射时混凝土衬砌的安全振速。

On the basis of the previous work, we make further study on the mechanism of the denucleation process, especially on the role of different cytoskeletal elements in the denucleation process. To clone and sequence a gene related to terminal differentiation of erythroblast, and construction of two cDNA libraries of erythroblast differentiation. The results of our study are as follows

本文在我室前期工作的基础上，对红系细胞终末分化中的排核机理作了进一步的探讨，克隆、测序并表达了一个与红系细胞终末分化相关的基因，另外，还成功地构建了小鼠终末分化和差减cDNA两个红系分化cDNA文库，为本室以后的基因克隆工作打下了基础。

In order to improve performance, as far as ISO-BARTMTFM paerboard Impregnator production enterprise KohlerCoating estimates, if you are using their new plastic unit, you can increase the line speed of about 40%, paste dasage more than can be reduced by 25%, and each steam room of steam pressure can be reduced by 50%~ 90%.

为了提高纸板性能，据ISO-BARTMTFM上胶机生产企业KohlerCoating估计，如果使用他们的新上胶单元，瓦线速度大约可以提高40%，浆糊用量能减少25%多，而每个蒸汽室里的蒸汽压力能减少50%~90%。
