简介：这篇散文在软事工程为分子的设计在一条合理、模块化的途径的发展讨论一些初步的想法并且为先进功能的材料建议结构、功能的synthons的想法。它回应由练习的材料染色体行动一试验制动火箭功能的分析RFA计划。在把分子的功能变成并且放大宏观的性质的层次结构的重要性被认出并且强调。根据在最后的材料的分子的片断的角色，有积木的二种类型：结构的synthon和功能的synthon。为需要的功能由特定的结构指导了，这些synthons能模块化地以构造分子的脚手架的各种各样的方法被联合。详细分子的结构然后精确并且模块化地被推出，设计并且综合。当装配结构和性质可以从原来的设计背离时，学习可以向目标功能允许分子的设计的进一步的精炼。策略在软fullerene材料和另外的巨大的分子的发展被使用了。有一些方面，很好还没被探讨：1功能和结构不是充分decoupled并且2装配层次结构越过不同长度规模对第二等的相互作用和分子的几何学敏感。不过，RFA途径由从化学和物理与考虑挑起创造性提供一个起点和一条其他的想小径。这为与超分子的格子形成设计软事是特别地有用的，作为在巨大的分子，在synthons相对独立于对方的地方。

简介：与科技的进步，人与几千米秘密地探索精力。作为一个thermophysical参数，起始的形成温度(IFT)在深好的设计起一个必要作用。然而，在钻前精确地预言IFT不是容易的。这个工作使用一个新方法分析地下的温度地的效果因素，并且假定人工的表面在表面温度和热电导率上消除人的错误和设备错误的骚乱。认为形成的不同分布是热电导率和岩石放射产生的热生产，一个优化模型被建立。与这个模型一起，纸预言了中国大陆人的主要的洞的底部温度科学的钻(CCSD)作为132.80
