Along with the development of bioinformatics and genetic localization, EST has already become a powerful tool for mapping, cloning and expression profiling of genes.
随着生物信息学和基因定位的迅猛发展，EST已成为基因定位、基因克隆、基因表达分析的有力工具。
All these "internal transfer" trend is not only because of the time but also because Zhang thinks that the localization of the literary should be a tool and she can't grasp the grand theme powerfully.
这种种“内转”趋向既是文学式微等时代因素所致，也同张洁对文学功能的工具化定位，以及把握宏大题材的力不从心有关。
