Based on the shell element degraded from the continuous body, concrete and configured steels are modeled by the layered shell element, and the vertical steels burdened with added loads are completed by the combined shell element. Then, with the smeared crack model, associated flow rule and Madrid hardening model, the material nonlinearity of the concrete is depicted. The stiffness matrix of nonlinear thin-walled shell element is deduced. As for RC multi-T girders subjected to transverse loads, the properties, such as crack expanding and steel yielding, are studied.

基于实体退化壳单元理论，采用分层单元模拟了混凝土和构造钢筋，采用组合单元模拟了受力纵筋；并利用弥散裂缝模型、关联流动法则和Madrid强化准则等来描述了混凝土的材料非线性，推导了非线性薄壁壳单元的统一单元模式，研究了横向荷载作用下RC多T梁上部结构的裂缝发展和钢筋屈服等性能。

With the growth-promoting bacteria HRO-C48 in plant rhizosphere as tested strains, the growth-promoting effect of chitosan on tomato and the influence of its combination with HRO-C48 on the biocontrol potential of the strain, including its induced resistance effect on grey mould in tomato and its biocontrol effect on damping-off of cucumber were determined in greenhouse.
