1. When measuring, based on the segmented contour line of thread, we used the compiled measurement program to calculate and measure the geometrical parameters of the internal taper thread as pitch, half of thread angle and taper angle. Precisions of pitch, half of thread angle and taper angle reached ±0.012mm, ±0.17° and ±0.018°. The results satisfied with the technique requirement of production. The reason of error was analyzed.

14. Both the imperative sentence and the statement sentence present a drop goes down firmly (Top-line Unmarked) after nucleus The top-line of imperative sentence and question sentence has a small but significant difference in the drop after the nucleus The nucleus of question sentence possesses a tendency to raise the first syllable that follows, indicating that it has the characteristics of a drop goes down uncertainly (Top-line Marked) The question information increases with an increases in the raise of the syllable behind the nucleus The bottom-line mapping of each type of sentence is also different The bottom-line of statement sentence fluctuates more, it is very low and its range of zigzag moving is wide The bottom-lines of imperative sentence and question sentence tends to be marked This experiment found out that the bottom-line of imperative sentence fluctuates less; and its ending is higher than that of the corresponding sections of statement sentence, showing a slightly marked form Being marked, the ending of question sentence are made to become higher, resulting in it having a small pitch antithesis more prominent than that of imperative sentence The imperative sentence, the statement sentence and the question sentence thus each has a unique bottom-line The pitch contour of the unstressed syllable that appears behind the nucleus is controlled by the pitch movement of the nucleus.
一、二部分的语调音高分析显示；汉语的语调类型是可以用音域的高音线和低音线的调节来说明。祈使句和陈述句都呈高音线骤落形式。相比之下，祈使句和疑问句的高音线在调核后的落差有细微而重要的不同。疑问句调核具有努力把紧跟其后的第一音节抬高的趋势，也就说明它有高音线渐落的特征，有别于祈使句的骤落特征。随着调核后一音节抬高的幅度加大，疑问信息量增加。三种句型的低音线趋向各自有所不同。陈述句的低音线起伏较大，低音线很低，显示出下延形式。祈使和疑问句的低音线是都呈上敛形式的。这次实验进一步发现，祈使句的低音线起伏较小，低音点比陈述句相应部分要高，呈弱上敛形式。在疑问句中上敛形式使低音点变高，使对偶距离变小的性质比祈使句更为显著，呈强上敛形式。祈使句的弱上敛、疑问句的强上敛和陈述句的下延形式并列，是三种不同的低音线形式。
