逻辑与艺几  [PDF]

Abstract: 法的精神即为法意,法意之司行即为流转。法意流转大别为逻辑演绎与类比推理两种风格迥异的模式。逻辑演绎主张以言敛意,在语言的地基之上以“方以智”的风格诠释法意流转,重“一”。类比推理强调言不尽意,以“圆而神”的风格艺几性地流转法意,尚“多”。方则易执,欠缺圆之神妙;圆则善变,差强方之智识。方圆互补是不通透的方智理路,立足于人性解放之上的自由变更才能真正实现法意流转的方圆无间之道。这正是法意流传的现象学解答

Abstract: Background The non conventional RTM (Restricted Tobacco etch virus Movement) resistance which restricts long distance movement of some plant viruses in Arabidopsis thaliana is still poorly understood. Though at least three RTM genes have been identified, their precise role(s) in the process as well as whether other genes are involved needs to be elucidated. Methodology/Principal Findings In this study, the natural variation of the RTM genes was analysed at the amino acid level in relation with their functionality to restrict the long distance movement of Lettuce mosaic potyvirus (LMV). We identified non-functional RTM alleles in LMV-susceptible Arabidopsis accessions as well as some of the mutations leading to the non-functionality of the RTM proteins. Our data also indicate that more than 40% of the resistant accessions to LMV are controlled by the RTM genes. In addition, two new RTM loci were genetically identified. Conclusions/Significance Our results show that the RTM resistance seems to be a complex biological process which would involves at least five different proteins. The next challenges will be to understand how the different RTM protein domains are involved in the resistance mechanism and to characterise the new RTM genes for a better understanding of the blocking of the long distance transport of plant viruses.
焦艺夜蛾的研究  [PDF]

昆虫学报 , 1988,
Abstract: 焦艺夜蛾HyssiaadustaDraudt是新发现的马尾松严重害虫.一年1代,以蛹在土中越冬,翌年3月初羽化,产卵于松针上,3月中旬孵化.幼虫食叶,一般7龄,幼虫期49—77天,蛹期约250天.前一年冬季和当年早春的干旱是该虫于当年大发生的主要因素.可应用741烟剂或白僵菌粉炮防治.大星步(虫甲)CalosomamaximowicziMorawiz是主要天敌,对害虫大发生有一定抑制作用.

Abstract: 本文在实验室研究了楔形截齿截割人工煤样时截槽间距对截割比能耗等的影响,得出了在不同截割厚度时的最佳截槽间距。最佳截槽间距的理论计算结果与实验结果两者是基本吻合的。
世界主要插花与花艺设计风格概述  [PDF]

世界林业研究 , 2004,
Abstract: 现代流行的插花与花艺设计风格有东方插花风格、西方插花风格、自由花艺设计风格以及前卫花艺设计风格。东方插花风格中可细分为日式风格和中式风格。西方插花风格可细分为圆形风格、线条风格、园林风格和时代风格。自由花艺设计风格的插花以东西方插花风格为基础,设计更为自由。前卫花艺设计风格则主要有架构、火凤凰、雕塑、抽象等类型。文中对上述内容进行了比较详细的分析。
树脂黏度变化对RTM成型工艺的影响 Influence of the viscosity change of resin on the RTM process  [PDF]

Abstract: 采用黏度计测定不同初始温度下环氧树脂的黏度,通过拟合法建立环氧树脂的工程黏度模型.将黏度模型引入树脂传递模塑(resin transfer molding,RTM)成型树脂流动模拟中,结合PAM-RTM软件模拟不同初始温度下树脂的填充过程,讨论树脂黏度变化对RTM成型过程树脂流动行为的影响.结果表明,随着树脂初始温度的上升,填充时间先降后升,在初始温度为40℃时填充时间最短.树脂黏度变化对大型结构件RTM成型影响显著.

Abstract: 百货广场桩基托换工程是深圳地铁一期工程关键工点之一,其托换轴力大,施工环境复杂。托换新桩采用挖孔桩,桩长20m。由于地层渗透系数大、承压水头高,截水帷幕的施筑是挖孔桩施工的关键。原位试验表明,以水玻璃为主材的双液注浆工法对本工点不同地层均取得了增加强度、明显减少渗透性的工程效果,经注浆处理后土层帷幕水力劈裂压力大于0.3mpa,可以满足本工点20m深挖孔桩截水要求。采用双组份聚氨酯堵漏注浆技术较好地解决了高承压水头下钻孔涌水问题。该工法机具体积小,操作简便,基本无废浆液产生,成功解决了本工点施作空间狭小的问题。实际施工表明,采用该工法及试验确定的注浆配方、参数和工艺施筑的截水帷幕截水效果明显,保证了挖孔桩顺利施工。
