The genome of infectious hepatitis B virus is a partially double stranded circular DNA, and that of replicative HBV is a covalently closed circular supercoiled DNA. The patients with chronic HBV infection manifest from non-active virus carrier state to severe active hepatitis, and 15%~25% of which will evolve decompensate cirrhosis and hepatocellular carcinoma.

Under the information theory, more applications are provided to those back analysis methods. Based on the Duncan-Chang E-B model, which can simulate earth-rock dam's non-linear mechanics behavior well, the paper introduced the nature coordinate system to the stress space. In this way, hydrostatic stress and stress deviator were decomposed each other.

论文以能较好模拟土石坝非线性力学行为的Duncan-Chang E-B模型为基础，通过引入应力空间下的自然坐标系，分解应力球量与应力偏量，从而导出一个在有限元计算中，位移对参数偏导数的闭合形式公式。

Methods divide 120 cases of closed fracture of tibia diaphysis into two groups under the same possible circumstances.each group has 60 cases. one group was treated by operating replacement, the other group was treated by closed replacement. two groups were treated by unilateral external fixation apparatus to fix after replacement.

选择120 例胫骨干闭合性骨折的患者，在条件尽可能相近的情况下分为两组，每组60 例，一组采用切开复位，另一组采用闭合复位，复位后两组均使用单边外固定架固定。

Results To construct several combining multiple regression mathematical models that use the arrested extent of epiphysis of sternal end of clavical and six joints to assess the chronological age of living subjects in Chinese Han female teenagers, and establish some Fisher's discriminatory analysis equations which are used to determine whether the chronological age of Chinese Han female teenagers has been to 14, 16 and 18 years old or not.

结果 建立了我国汉族女性青少年利用锁骨胸骨端及6大关节骨骺闭合程度联合推断活体年龄的多元回归数学模型，推导出判定我国汉族女性青少年是否已满14、16和18周岁的Fisher's两类判别分析方程。
