"With the first subject, after about 20 hours of training, his digit span had risen from 7 to 20," Ericsson recalls.
“对于第一个实验对象，经过大约20小时的训练，他的数字跨度从7上升到20。”爱立信回忆道。
SPAN button. This button is used to select either 10KHz, 1KHz, or 100Hz steps for the VFO. The currently selected step is indicated by a line under the relevant digit on the Frequency Display.
通带按钮，此按钮用来在VFO（可变频率震荡器）上选择10KHz，1KHz或100Hz的步长频率，当前所选择的步进，是在「频率显示」中的相关数字下面，用一条线显示出来。
This study is relatively innovative because it combined several factors such as emotion and age and made a survey on their influence on digit working memory span.
在该研究中，将情绪与年龄因素结合起来考察对数字工作记忆广度的影响，具有一定的创新性。
CONCLUSION: It is feasible to change the digit span test in Wechsler Intelligence Scale from individual test to group test.
结论：改变韦氏智力测验中的数字广度的测验方法，把该个别测验作为团体测验使用是可行的。
There were age and group main effects both on digit span performance and space span performance( P <0.05), but no interactive effects were revealed between age and group ( P >0.05).
将两组按照年龄分为高年龄组和低年龄组进行协方差分析，数字广度和空间广度测验均表现出显著的组别和年龄效应（均P<0.05），但组别和年龄无交互作用（均P >0.05）。
Therefore, we adopted digit working memory span as a way of the test on the working memory span based on the hypothesis that emotion and age will influence the span of digit working memory.
在本研究中我们采用数字工作记忆广度来测试工作记忆广度，并假设情绪与年龄因素会对数字工作记忆的广度产生影响。
Methods 193 normal subjects were tested by mini-mental state examination (MMSE), word immediate recall and word delayed recall test, clock drawing test, digit span test and verbal fluency test.
方法：对193名正常老年人采用简明智力状态检查(MMSE)、词语即刻回忆和延迟回忆、画钟表、数字广度和词语流畅性测验等神经心理学测验进行认知测评。
