In recent years, sweet potato virus disease （SPVD） has severely affected the production of sweet potato in China. In order to select chemical agents to prevent sweet potato from being infected with SPVD, 14 pesticides were sprayed on the plants of sweet potato infected with SPVD, and the relative mRNA level of the viruses in the leaves and physiological indicators of sweet potato plants were detected. The results showed that after the application of most of the pesticides, the relative mRNA level of the two viruses that caused SPVD decreased, and the chlorophyll content and biomass of sweet potato infected with SPVD increased significantly or extremely significantly. Among the pesticides, BASF virus liquid, 0.1% physcion and Aolike powder for cucumber virus were proved to be the best, as the chlorophyll content and stem length of sweet potato increased significantly. The experiment indicated that the pesticides could reduce the harm of SPVD to sweet potato.

The IbSAP15 gene is a member of the sweet potato stress-associated protein gene family. It is special because it has two AN1 domains and no A20 domain. We conducted a preliminary study on the function of the IbSAP15 gene. p35 S::IbSAP15 was transformed into wild type Arabidopsis Col-0 by Agrobacterium-mediated transformation method. We tested the expresssion level of Ib SAP15 gene in the transgenic lines by real time PCR, and selected the L4 with higher expression level and L6 with lower expression level to further study. We investigated the responses of L4 and L6 to salt stress at three stages, i.e., seed germination, seedling growth, as well as mature plants. We also examined the physiological and biochemical changes in the leaves of L4 and L6 plants under salt stress. The main results are as follows: Seeds of p35 S::IbSAP15-L4, L6 and Col-0 were placed on MS medium containing 0, 50, 100, 150, or 200 mM NaCl, and the germination was observed. The results showed that the germination rates of L4, L6 and Col-0 seeds on media containing 0 mM NaCl were nearly 100 %, The germination rates of L4 and L6 on the media containing 50 mM to 200 mM NaCl was higher than those of Col-0. The germination rate of L4 was 43.75%, L6 was 33.75% and Col-0 was only 17.5% on the media containing 150 mM NaCl.（2） 3-day-old seedlings of L4, L6, and Col-0 were transferred to MS medium containing 0, 50, 100, 150 or 200 mM NaCl, and cultured for 8 d before the root length was measured. The results showed that the roots of L4 and L6 were longer than Col-0 on the media containing 0 to 150 mM NaCl. The root length of Col-0 was 35.2 mm, L4 was 42.2 mm, and L6 was 39.8 mm on the media containing 100 mM NaCl. The fresh weight of the transgenic Arabidopsis thaliana containing 0 to 150 mM NaCl media was heavier than Col-0. For example, the fresh weight of L4 was 18 mg, and L6 was 16.3 mg while Col-0 was 9.6 mg on the media containing 150 mM NaCl.（3） The survival rates of L4 and L6 were both 100%, while

为进行双悬臂搬运桁架结构优化设计,基于三维参数化建模、有限元分析及数值分析建立了克里金(Kriging)响应面法与多目标遗传算法(MOGA)相结合的优化方法,实现了以桁架的强度和刚度作为约束条件,以桁架质量为优化目标的全局优化方法。根据实际桁架的作业情况,对2种特殊工况进行结构分析,表明原始的桁架结构存在较大的安全裕量。采用4种不同方法对桁架静力学分析进行响应面建模,结果表明Kriging方法构建的响应面模型决定系数R2最高。将MOGA算法与Kriging响应面相结合对桁架进行迭代优化,结果表明优化后的桁架在满足强度和刚度的前提下,实现了质量减小20.00%。
