Water-maze and step-down method were used to test whether theanine would affect Mice's learning and memorialcapabilities. 采用跳台法及复杂水迷宫法,观察茶氨酸对小鼠学习记忆能力的影响。
Nanometer pore arrays alumina films were prepared by anodizing of highly pure aluminum foils in sulfuric and oxalic acid solution. The porous alumina layers were detached from the Al substrate by using step-down voltage or solution method. 在草酸和硫酸溶液中,通过阳极氧化高纯铝片的方法制备了纳米氧化铝膜孔阵列,用阶梯降压法或溶解法将氧化铝膜层和铝基底分离。
This paper gives an introduction of Lenth Method, Dong Method, Step-down Lenth Method and some methods suggested by Venter and Steel in 1996 and 1998. Enlightened by Step-down Lenth Method, we propose Step-down Dong Method. 本文向读者介绍了Lenth方法,Dong方法,下降Lenth方法和Venter和Steel分别在1996年和1998年提出的一些方法,并且仿照下降Lenth方法,构造了下降Dong方法。
Furthermore, this paper established the controlling mode of step-down current method and studied its effect on the coating process and realization method in the phosphate electrolyte solution as well. 另外,在恒流控制的基础上,提出了阶梯降流法的控制成膜方式,并研究了其在磷酸盐系电解液中具体的实现方法及其在成膜过程中的作用。
