The plant expression vectors were constructed and two genes were transferred into A. thaliana and N. tabacum, antikanamycin plants were obtained.4. The trials of adventive bud regeneration directly and callus induction was conducted to select out the optimal explants and formula. The results revealed that double scale can produce 13~16 adventive buds per centimeter in MS medium added 10.0 mg/L 6-BA, 1.0 mg/ L NAA, 40 g/L sugar and 7.5 g/L agar. Scale, leaves, scape and different tissue of flower can be induced to produce callus in appropriate medium, but the filament with anther was the optimized explant.

The main factors affecting the soil-structure interface behaviors were found experimentally and theoretically, including: 1 the thickness of the interface that is five to six times the average grain size of the soil; 2 the aeolotropy of interface, which is responsible for anisotropic response of the stress-strain response of the interface; 3 two physical states, including crashing and compression of the soil near the structure surface, which govern the stress-strain response of the interface strongly; 4 two shear deformation components due to sliding and constraint of the structure surface relative to the soil respectively, which forms the deformation of the interface; 5 the volumetric strain due to dilatancy, which is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. 4. A unified constitutive model of the interface, based on new elasto-plasticity damage theory, was developed. It was confirmed to be effective for the conditions considering monotonic and cyclic shearing, coupling effect of shear and volumetric strains, evolution of physical state, micro-structure aeolotropy of the soil and the resulting aeolotropy of the interface as well as the three normal boundary conditions stated above. 5. 2D and 3D finite element formulations of the present model were derived and incorporated into the FEM codes. They were applied to the evaluation of practical engineering problems with different typical interfaces between soil and structure. The new model was shown to be reasonable and effective.
确定了粗粒土与结构接触面厚度约为5~6倍的平均粒径,首次揭示了接触面的细观结构异向性以及由此所引起的宏观剪切异向性,发现了在单调和往返剪切荷载作用下土颗粒破碎和剪切压密两种物态变化机制共同支配着接触面力学性质的变化,通过细观分析证实了接触面的变形可分解为一般同时发生的土与结构交界面上的滑移变形以及结构面位移约束范围之内土体本身的剪切变形两部分,观测到接触面受剪时表现出明显的相对法向位移,并可分解为可逆性和不可逆性两个分量;(4)建立了第一个能够统一地描述单调与往返剪切特性、剪应变与体应变耦合特性、细观结构和宏观剪切异向性以及土颗粒破碎等物态变化特性的土与结构接触面弹塑性损伤本构数学模型,并采用多种法向边界条件复杂加载路径的试验成果验证了新模型的合理性和有效性;(5)提出了新模型的二、三维有限元格式并结合实际边值问题进行了应用计算分析,比较了不同接触面本构模型对计算结果的影响,证实了新模型及其有限元格式不仅能够合理地描述土与结构接触面的主要力学特性,还能够较好地反映土体与结构物在接触面处的滑移、脱开等不连续现象。

The high inoculum levels increased the bacterial growth and shorten the time for antifungal substance production. The powder of rice, soybean cake, yeast, and wheat bran, CaCO3 and KH2PO4 were better nutrients for the bacteria growth and antifungal substance production. There were two stages during the fermentation process at 30℃. The growth of bacteria increased at the first 24 h and the pH of broth rose, but no antifungal activity was observed until 41 h later and reached to the highest level at 114 h.
基本营养物质的初步筛选试验证明:大米粉、豆饼粉、麦麸、酵母粉和CaCO3及KH2PO4是发酵培养基中最佳的营养物质,可满足抗菌物质产生对碳、氮和矿物质的营养需求。B-903的发酵过程可分为两个阶段:在30℃下,24小时内,细菌数量达最大值,pH值由低向高变化,但此阶段检测不出抗菌物质的活性;第二阶段,培养41小时后,抗菌物质活性开始显露,至112小时后达最大值,pH值也逐渐由高变低。

People have paid attention to the pollution of soil and water quality caused by using organic arsenic chemistry reagent to prevent and cure apple-tree canker in our apple area, so it has an important purpose to seek a harm-free way for sustaining development of apple. The tests studied the effect of prevention and cure on apple-tree canker with EM mud, EM liquid, 40%'Fumeishen powder' and contrast. The results showed that the EM mud was superior to the EM liquid, 40% 'Fumeishen powder' and contrast. The prevention and cure effects of EM in 2006 and 2007 were 92.7% and 93.5%, while the recurrence rates of canker scars 1.8% and 2.8% respectively. And the healing effect of scar is 50.4%. So, it was considered as a new way to prevent and cure apple-tree canker with EM mud.
