1.
This thesis, on basis of an investigation, the traceable approach, a longitudinal case as well as a statistical analysis of the data, probes into the development of counting ability among children in China, including when they grasp the cardinal word principle, when subitization emerges in them, and when they adopt the way of counting to answer“how many”questions.
第三章通过指定数字输入实验,指定数字输出实验及数字直觉测试,结果表明:1)儿童在三至四岁之间,大部分已掌握基数原则,四岁后几乎所有儿童都能掌握此原则;2)儿童最早采用数字直觉回答“共计多少”的问题,三岁开始运用数数的方法来解决此类问题;3)儿童数字能力的发展随着年龄的增大而增强,四至四岁半这组儿童结果最佳,各组三次实验数据之间存在密切联系。

补充资料：肺循环阻力(或全肺阻力)
肺循环阻力(或全肺阻力)
pulmonary circulation resistance
血液在肺部血管内流动时和血管壁之间的摩擦力和血液内部的摩擦阻力。肺动脉管壁较薄，分支短而管径大，故肺动脉的可扩性较大，对血流的阻力很小，仅0.12PRU(外周阻力单位)。肺循环动脉部分总的阻力和静脉部分总的阻力相等，故血液流动时在动脉部分的压力降落和静脉部分的压力降落相等。
