The egg production of a week et al was also analyzed . 18 pairs of microsatellite primers were screened from chromosome 1 and chromosome Z, the primers were designed to allow optimal performance of the markers, in sets containing multiple microsatellites, on ABI3100 sequencers. We determined there were correlation among 13 microsatellite markers and 19 characters in 25 egg traits through least square means. At the same time, we calculated correlation among characters of egg traits in silkies.

This thesis presents the preliminary study of the influence of sentence stress on prosodic features in Mandarin, and of the relationship between duration and pitch under different sentence stress levels. The results show that: The pitch is the most important factor which carries the sentence stress, with the increase of the sentence stress level, the peak of distribution contour of pitch moves towards high frequency area. In the case of"Stress"and"Light", two peaks are found in the distribution contour of duration, which means that the duration of some words are affected by sentence stress, but of others are not. The relationship between pitch and duration in"Normal","Stress"and"Light" are un-correlated, positive correlation and negative correlation respectively.

研究了汉语语句重音对音长和音高的影响、及音长和音高之间的相互关系，结果指出：（1）音高是汉语语句重音的基本表达手段，随着语句重音级别的提高，音高的统计分布曲线向高频方向推移；（2）在连续语流中的词被&重读&和&轻读&的情况下，音长分布出现双峰，表示它们的音长存在着受语句重音的影响和不受语句重音的影响两种情况；（3）词在&正常&、&重读&和&轻读&三种情况下，音高和音长的相互关系分别是：不相关、负相关和正相关。
