By Lagrange dual and scalarization of vector optimization, characterizations of solutions for which objective mapping satisfies weak convexity conditions are shown. The strongly and weak dual theorems for generalized subconvex-like mapping are obtained.

通过适当定义对偶问题和向量优化问题的标量化研究各解之间的关系，刻画目标映射满足弱凸性条件的优化问题解的特征，在目标映射是广义锥次类凸的条件下给出有关的对偶定理。

In the study of finiteness conjecture, there are two important conclusions, that is Revised Dulac"s Theorem and Il"yashenkos Theorem. But the discusses and demonstrations of these two theorems are very brief and simple in existing documents.

在有限性猜测的研究中有两个十分重要的结果，即修正的Dulac定理和Il'yashenko定理，现有的文献对这两个定理的讨论和证明非常简要。

This study will assess elementarily the security and effectiveness of The root and leaf of Panicled Fameflower through the experimental studies on their pharmacodynamics and acute toxicology, provid possibly theorems and experimental foundations for Panicled Fameflower' s edibleness, planting and study.

本课题通过土人参根、叶的药效和急性毒性实验研究，对土人参根、叶治疗"脾虚"证、土人参叶"解毒消痈"的疗效和部分作用机制做出初步评价、并取得土人参根、叶急性毒性数据，为保健中药蔬菜土人参的食用提供客观的药效学和急性毒性的实验依据，以促其进一步推广应用、种植、研究。
