Through correlative analysis and path analysis, it finds that (1) the family environment and the colleges and universities environment have direct and indirect influence on self-identity development of students; and (2) the family environment and the colleges and universities environment exert the major effect on self-identity development of students through identity style as mediational variable, so identity style becomes the explanatory base of self-identity status. That is, the predictive effect of diffuse/avoidant identity style for identity diffusion, normative identity style for identity foreclosure, and information identity style for identity achievement respectively is most significant; and (3) family environment that is helpful, supportive, warm, expressive, and promote autonomy and independence possibly makes students form identity achievement or identity moratorium, family environment that is excessively cohesive and warm but lacking independence possibly promote students to form identity foreclosure, and family environment that lacks of supportive and warm possibly make students form identity diffusion; and (4) colleges and universities environments that have better relationship system, clear developmental purpose, and promote to pay attention to societal concerns, critical and explorative qualities, and provide healthy, expressive, democratic, open atmosphere facilitate identity development, in turn form advanced identity. Colleges and universities environments that only emphasize the receival of colleges and universities aims, order and instilments, and scarcely encourage critique, exploration, individuation possibly make students form identity foreclosure. However, the ones that is remote relationship system, and lacking support, and students don't cognize the aim of colleges and universities possibly make students form identity diffusion.

通过相关分析、路径分析发现：(1)家庭环境和学校环境对大学生自我同一性有直接和间接的影响；(2)家庭环境、学校环境对大学生自我同一性影响主要以同一性加工方式为中介变量，同一性加工方式成为自我同一性状态的解释基础，弥散—回避定向同一性风格对弥散型同一性预测力最大，信息定向同一性风格对成就型和延缓型同一性预测力最大，常规定向同一性风格对排他型同一性预测力最大；(3)相互支持、帮助、关心、自由表达和鼓励自主和独立的家庭环境促进大学生同一性的发展，形成成就型或延缓型同一性状态，过度亲密而缺乏独立性特征的家庭环境可能形成排他型同一性状态，而缺乏支持性，关系疏远的家庭环境可能形成弥散同一性状态；(4)良好的关系系统，明确的发展目标，鼓励学生对社会事务关注、倡导批判和探索精神，塑造良好、健康、可供自由表达、民主、开放的文化氛围的大学校园环境促进大学生同一性发展，形成高级、成熟的自我同一性，而一味强调学校目标的接受，强调秩序、灌输，缺乏对批判、探索、个性发展鼓励的学校环境有可能使学生形成排他型同一性状态，但若学校的关系系统疏远，缺乏支持性的民主的风格，目标不能被学生明确感知的学校环境则可能影响学生形成弥散型同一性。

Researching on the decision-maker's behavior hypothesis and classification principle in incomplete informational risk assessment, this paper built the rational decision-making route as①releasing the sequential or partible hypothesis of individual preference and alternatives independence condition in order to satisfy the actual decision-making;②keeping the optimal result of group decision-making according as the thought of"Binary comparison"of sequence path independence condition SPI building the hierarchy structure in opening frame of discernment to increase granularity of discernment.

研究不完全信息操作风险评价的决策者行为假设和分类方法，构建理性决策路径和决策机制：①放松Arrow选择理论的决策者个人偏好连续或可分假设、无关方案独立性条件，以满足决策过程的实际情况。②构建开放的决策识别框架，依据序贯路径无关条件的&两两比较&思想，保证群体决策结果的最优性；在开放的识别框架中建立层次结构，增加识别粒度。将主观信息表达转化为专家对某一属性判断的基本可信度分配，运用证据理论处理不完全信息的融合问题。③基于包含度的分层约简方法降低决策复杂度。

本文通过文献查询整理与实地调研相结合的方法，归纳现今国内外相关行业对世博会开放空间的研究现状，总结世博会开放空间的发展历程。

The open source software companies should know the correlative laws very well on the side of rights and responsibilities to avoid tort, and should have own counselors. The users of open source software should use the approved software for the best of abilities. When dissensions happen and bargain doesn't work, the legal process should be taken action in local courts.

作为开源软件公司，应熟知和了解国家相关的政策和法律，确认自己的权利和义务，避免违规操作，设立法律部门或人才；对使用开源软件和接受服务的企业来说，要尽量采用经过版权纠纷检验过的开源软件，尽量选择本国法院作为开放源代码软件诉讼解决法院，尽量采用和解的方式来解决开放源代码软件商业化法律纠纷。

An open-ended mathematical problem, to which there is not only one method to solve and not the only answer, draws the students attention to think and find out the various answers to the problem by themselves instead of depending on their teachers and textbooks. Students are changed into the active thinkers and finders from the passive accepters. In this way studcnds are guaranteed to play the main role and helped to form their self-awareness and independence of their personalities.

数学开放题由于其自身的开放性质，不再是方法唯一，答案唯一，这就吸引学生不依赖教师和课本，独立地去探索和发现问题的各种各样的答案，学生由知识的被动接受者转变为知识的主动发现者和探索者，保障了学生的主体地位，从而在利于学生自我意识和独立人格的形成，为培养学生的创新精神奠定了基础，对全面推进中学数学素质教育有重要意义。

It contains 215 bp, named as ZM908. Biosoftware anlysis sug gests that ZM908 gene properly belongs to the mRNA-like non-coding RNA gene which is purposed to lack of obvious open reading frame (the longest possibly contains 98 AA), contain poly tale and have stable RNA structure in vivo. ZM908 contains high conserved nucleotide sequence with ZM401 (including 371-598bp, 698-847bp and 929-1047bp in ZM908). The highest conserved sequence reaches 86%.The RT-PCR analysis result revealed that ZM908 is transcriptable.

基因分析显示这段序列含1215bp，命名为ZM908；采用生物学软件对ZM908序列和结构进行分析，表明该基因缺乏明显的开放阅读框架，序列中最长可能的开放阅读框架仅编码98个氨基酸，具有poly尾部结构，RNA分子具有稳定的二级结构，符合非编码RNA基因的特点，可能属于类似于mRNA的非编码基因；ZM908与ZM401有高度保守的区段(ZM908序列中有三段和ZM401是高度保守的，分别为371-598bp，698-847bp和929-1047bp)，相似性最高达到86%。

42 thoracolumbar fracture patients were divided into two groups: 18 cases were included in the Sextant percutaneous pedicle screw fixation group and 24 cases were in the open pedicle screw fixation group. The perioperative index including correction of kyphosis, recovery of neurological function and relief of the low back pain was compared.

2006年12月～2009年3月选择42例胸腰椎骨折患者给予附加伤椎固定的三椎体六钉固定，分别采用Sextant系统下微创经皮椎弓根螺钉内固定手术（18例，微创组）和传统开放椎弓根螺钉内固定手术（24例，开放组），对两组患者围手术期相关指标、后凸畸形矫正情况、术后神经功能恢复、腰背痛改善等进行比较。

Ray florets elongated faster than disc florets from phase P3, when tetrads of haploid microspores appeared, and the pigmentation of the ray floret began when the pollen grains showed germination apertures in the disc florets of the first whorl. The effects of light, sugar and GA3 on flower growth and development were investigated in vitro. Inflorescences in the P2 phase or later could grow and bloom in vitro, and sucrose, GA3 and light promoted flowering.

研究表明，分化完全的舌状花在P3期、即花粉细胞四分体出现之后长度超过盘状花，在盘状花的雄蕊出现具有萌发孔的花粉粒之后，舌状花开始着色。P2以后的花序经离体培养可以开放，光、糖和GA3对花序的生长和开放有显著的促进作用。

Starting from the development course and demand of landscape, construction of public open space for the citizens was discussed. Then urban public landscape design principles and integration were discussed from dotted-like and linear space perspective.
