1·There are a lot of data of wax deposit in oil well home and abroad, in which most are analysis on macroscopic property while systematic researches of oil mechanism are very few.
国内外油井结蜡分析的资料有很多，其中宏观性质上分析占大多数，原油机理方面的系统研究很少。
2·The apparent arrow of time emerges as a property of the macroscopic system, but it's not there in the laws that govern the individual particle interactions.
很显然时间箭头成为了宏观系统的一种性质，但没有定律来控制单个原子间的相互作用。
3·Based on the aggregate relationship between of polycrystals and single crystals, orthotropic property of microscopic single crystals could be defined from macroscopic material by numerical simulation.
假定高温合金材料是单晶材料的集合体，通过数值模拟的方法，利用多晶与单晶之间的关系，可以由宏观材料参数估计微观单晶晶粒的材料属性。
