trace material meaning in English
痕量物质
Examples
- Str locus can be multiplex amplificated , so it is very useful for trace materials
Str基因座还可以进行复合扩增,对微量检材的鉴定特别有意义。 - 3 ) in order to manage and trace materials in mes , the concept , theorems and properties about a special set named s ( i ) are put forward . based on the properties and theorems of s ( i ) , a new method is presented to describe the material process state . it is a concise way using the material process state vector and material process state value to deal with the materials which provides a powerful mathematic tool for material management in mes
3 )面对制造执行系统中的物料工艺状态描述的困惑，建立了集合s ( i )的定义以及集合s ( i )的相关定理和性质，并在集合s ( i )理论的基础上，研究了如何描述物料工艺状态信息，从而为制造执行系统中物料管理和物料跟踪提供科学的方法。 - In the need of adulterating target materials with metal clusters as tracing materials , we calculated the cluster behavior of al materials in theory . the preliminary study was carried out in no more than 7 atoms , considering the much time in calculation and limitation of theory model gaussian98 program , the b3lyp method and the 6 - 311 + g * basis function were used in the calculation
由于靶材料掺入金属团簇示踪材料的需要，我们对铝材料的团簇行为进行了理论计算，考虑到计算量和理论模型的缺陷，初步研究是在7个原子以内进行的。
