arelationship between delay number and the delay time varies among manufacturers. As a general rule the delay between delay numbers in the millisecond series, is 25 ms. In the half second series the interval is 500 ms. Tables 8.8 and 8.9 present typical delay numbers and intervals for the tw...
aWhen a relationship between two variables changes,the entire curve shifts.In this case a tougher grading policy alters the relationship between study time and grades.To get a C one must now study 12 hours per week(point R),not just 8 hours(point M). 当二可变物之间的一个关系改变时,整个...
Thus, periodontitis among works who worked long hours could be aggravated by increased vulnerability from infectious agents due to not enough time to recovery of work stress.
