We study the relation between topological sigma models and generalized geometries. The existence conditions for the most general type of topological sigma models obtained from twisting the N=(2,2) supersymmetric sigma model are investigated, and are found to be related to twisted generalized Calabi-Yau structures. The properties of these topological sigma models are analyzed in detail. The observa....

六标准差从1987年在摩托罗拉公司推行至今，已近20个年头，从一开始制造面的改善，延伸到非制造性的企业流程当中，它不但有效地变化员工能力与态度，也为企业带来突破性的营运改善，全方位提升企业竞争力；但事实上，六标准差管理活动导入对企业是一大变革性的挑战，因为其中牵涉策略、组织。。。。

The aims of disaster study and risk study are tent to unanimousness, both will offer the theoretical basis for sustainable development models. Regional safety construction based on disaster study is converting into regional risk management system based on risk study. So the authors consider that sustainable development model is the regional development model under a certain risk level, and the risk level relies on the regional safety construction level that integrates the regional economic level and social cultural system. Strengthening subject construction of disaster and risk study in China, national laboratory construction, and organization and practice of key items are imperative. And we should put the study emphasis on the vulnerability assessment system and models, risk assessment system and models, disaster and risk management mode of typical region, disaster and risk emergency control scenario, disaster and risk regions.

灾害与风险研究的目标正在趋向一致，都集中在为可持续发展模式提供科学依据；基于灾害研究的区域安全建设正在向基于风险研究的区域风险管理体系转变，由此认为可持续发展模式就是接受一定风险水平条件下的区域发展模式，一定风险水平依赖于由区域经济水平与社会文化体系相关联的区域安全建设水平；加强我国灾害与风险科学研究的学科建设、国家实验室建设、重大项目的组织与实施已势在必行；重点开展灾害脆弱性评价体系与评价模型、风险评价体系与风险评价模型、典型区域灾害与风险管理范式、灾害与风险应急控制预案、灾害与风险区划等方面的研究。
