NAAS drew up an operational plan for an academy of agricultural sciences, three national crop research institutes and a university dedicated to agriculture. NAAS起草了一份操作计划来建立一个农业科学院、三个国家级农作物研究所和一所农业大学。该计划目前正在与政府沟通。
Soap-free emulsion copolymerization of methyl methacrylate ( MMA) and butyl acrylate ( BA) in the presence of water soluble ionic comonomer, sodium allyl sulfonate ( NaAS) and of the initiator, potassium persulfate ( KPS), were carried out. 经红外光谱检测证实,离子型单体烯丙基磺酸钠(NaAS)参与了甲基丙烯酸甲酯(MMA)与丙烯酸正丁酯(BA)的无皂乳液共聚合。
The discovery of NAAs is theoretically significant in providing a challenge to the traditionally accepted "clonal selection theory". NAA的发现,向经典的克隆选择学说提出了挑战,具有重要的理论意义。
A spectrum of normal functions have been attributed to NAAs, including the maintenace of homeostasis of the organism, immune regulation, resistance to infection, catalytic activity, and transport of biologically active molecules. NAA具有广泛的生理功能和作用,包括:机体内环境稳定的维持、免疫调节、抗感染、催化活性、小分子活性物质的运送等。
Amongst NAAs themselves a network structure is formed by idiotype-antiidiotype interactions. NAA内部通过独特型-抗独特型相互作用形成一个网络结构。
