In this paper we define the concept of Projective Blaschke manifolds and extend the theory of equiaffine differential geometry to the projective Blaschke manifolds. We prved that if M be a complete projective Blaschke n-sphere and its universal covering manifold is isometric to a complete (n+1) dimensional parabolic, elliptic or hyperbolic affine hypersphere, then M is a quotient space of E^n, S^n or D^n by a isometric subgroup of its corresponding spaces.

在这篇文章中我们定义了射影Blaschke流形的概念，将等仿射微分几何的理论推广到了射影Blaschke流形，并证明：如果n维完备射影Blaschke 超球面 M 的通用覆盖流形分别是完备的抛物型、椭圆型或双曲型仿射球，则M分别是n维欧氏空间、n维超球面或n维单位圆盘关于各自空间的一个等距离散子群的商，从而对完备射影Blaschke 超球面进行了分类。

Recombinant ptotein made up 39.2%(pET-20b-bglA) and 33.5%(pET-28a-bglA) of the total proteins in the intracellular fraction, the solubility proportion of the enzyme up to 32.8%(pET-20b-bglA) and 40.1%(pET-28a-bglA), the activities of the enzyme were 66.8 (pET-20b-bglA) and 71.2 U/mg (pET-28a-bglA). These results showed that E. coli BL21-CodonPlus (DE3)-RIL with argU tRNA, ileY tRNA and leuW tRNA genes helped to improve expression of the enzyme through enhanced identification of the rare codons AGA/AGG, AUA and CUA. Further optimized the conditions for inducing, the solubility proportion of the enzyme was 70.6% at 16 °C and 1.2 times higher than 37 °C. The solubility proportion of the enzyme increased from 12.3% to 32.8% when IPTG concentrations dropped from 1000 μM to 25 μM. The recombinant enzyme was purified by heat treatment, DEAE Sepharose anion-exchange chromatography and TOYOPEARL HW-55F.
