In Brunn-Minkowski-Firey theory, we establish two extremum properties of the new ellipsoid; Then we generalize Petty\'s affine projection inequality and monotonicity results related to affine surface area to L_p—affine surface area; We establish the Brunn-Minkowski type inequalities for the volume of the L_p centroid body and its polar body with respect to the normalized L_p radial addition. At last, we introduce the minimal L_p—mean width of a convex body and generalize the minimal mean width to the Brunn-Minkowski-Firey theory.

For rapid tests, in which stability of the conjugate is critical for avoiding false positives, this predisposition to agglutinate can become a major problem.

对于快速诊断试剂来说，标记物的稳定性对避免假阳性是非常重要的，因此易凝集的特性会成为大难题。

Further more, animal erythrocytes specificity, carbohydrate-binding specificity, thermostability, and influence of pH and Ca2+ to the agglutinative activity were compared among the lectins of serums and muscles from 5 crustaceans. The results showed that there were evident difference in these aspects between serum and muscle from the same crustacean, and it indicated that the lectins of serum and muscle from the crustacean were different in nature.

进一步比较5种甲壳动物的肌肉和血清中凝集素的动物细胞专一性、糖结合专一性、热稳定性、pH及Ca~(2+)的影响试验，结果上述几方面在同一种甲壳动物的肌肉和血清间都存在明显差异，证明同一种甲壳动物的肌肉和血清所含的凝集素的类型不同。

The results show that the shape of meniscus is non-homogeneous because of the structure of the rectangular mold, and the height of meniscus will enlarge as increasing the power, and at the same time the meniscus fluctuate aggregately. The coil should be placed near the top of the mold and the initial free surface level should be placed in the middle of the coil in practice.

结果表明：由于矩形电磁软接触结晶器本身的结构限制，其弯月面沿周向上的分布具有不均匀性；随电源功率增大，弯月面高度增大，同时波动加剧；实际生产中线圈应尽量靠近结晶器口部位置安装，有利于提高弯月面高度和增强弯月面稳定性；浇注过程中，应该使浇注液面尽可能的控制在线圈中心偏上位置；当电源频率增大时，应该同时适当的提高电流来保证软接触效果。
