On strength computation,the finite element models of rotating mirror were established according to the real structure of the mirror,and the rotating three-faced beryllium mirror were analysed.Results display that the surface deformation magnitude of the mirror is approximately 0.334 6 μm,and the maximum stress is 0.204 GPa at 600 m/s of edge linear speeed.The regions of maximum stress are on the axial hole and symmetric to symmetrical planes of mirror body,and keep beelines to surfaces.On the modal analysis,the results show that the first and second modals of bending vibration exist around 3.4×105 r/min and 6.6×105 r/min,which appear binate and orthogonal respectively,and another modal belongs to the first torsional vibration that occurs by 5.13×105 r/min.

运用该方法得出转镜镜面变形量、内部应力分布和振动模态参量的定量数值：在边缘线速度600 m/s下，三面体铍转镜的最大变形量为约0.334 6 μm；最大应力0.204 GPa，位于轴孔附近并与镜面距离最短处；两个在互相垂直平面内的一阶弯曲振动模态发生在3.4×105 r/min附近，一阶扭振点位于5.13×105 r/min附近，两个二阶弯曲振动点位于6.6×105 r/min附近。

As an application example, we applied BioWarehouse to determine the fraction of biochemically characterized enzyme activities for which no sequences exist in the public sequence databases.

作为一个应用例子，我们应用BioWarehouse来确定在公共序列数据库中没有序列存在的生化特征的酶活性的分数。

It was confirmed that the analogous relations between unsteady one-dimensional chromatographic process and steady two-dimensional CAC process proposed by Wankat still exist regardless of the bioreaction, and the analogous results were shown. A mathematical relation between the feed and the eluant flowrates was established for keeping the CAC in good operation. The optimization of the hybrid process were also discussed.

从理论上指出了在伴有生物反应时，二维稳态CAC过程与一维非稳态间歇色谱过程仍然存在类比关系，并给出了类比结果，推导了使CAC过程处于良好操作状态时进料及洗脱速率应满足的数学关系，对于生物反应液相色谱分离耦合过程的优化原则也进行了初步探讨。
