国际音标教学之我见

学好语音是学好英语的基础,而学好语言的关键在于学好国际音标。人的感情、思想要靠说表达出来,这就要求说的准,也就是说,每个人在说的时候,要发好每个音,读准每个单词。

叶音始于何时

徐邈未使用“取韵”一语,叶音不始于徐邈。就现有材料来看,叶音当始于沈重。叶音前的某些古音之注,或有叶音音理上的疑似,可视为叶音之萌芽。

Correcting for non-compliance when determining colonic transit time with radio-opaque markers

The use of radio-opaque markers and abdominal X-ray is the standard method for determining colonic transit time(CTT). However, when there are deviations in the intake of these markers by participants in clinical trials it is desirable to improve observations by introducingcorrections, where possible. To date, there is no standard procedure to adjust for such deviations. This report proposes a series of alternatives based on possible scenarios for deviations from the intended intake of radio-opaque markers. The proposed method to correct for missed or delayed consumption of radioopaque markers can help to increase the accuracy of the CTT measurements in clinical trials.
