Objective To investigate bone nutritional status of neonates and their mothers as well as the correlation between them by estimating the concentrations of 25-D3, calcium and phosphorus in maternal blood and cord blood at birth, and by measuring the bone speed of sound of neonates and their mothers with quantitative ultrasound within 3 days after birth. Methods The concentrations of 25-D3, calcium and phosphorus in the serum were estimated both from 32 pregnant women who had a term delivery and from the umbilical cord at birth.

Five microsatellite loci (OarHH55, OarJ1A, McM53, BM1329 and BM143) with tight link to FecB gene in small-tailed Han sheep were selected to analyze their polymorphism in the population of small-tailed Han sheep. And its correlation with high reproduction performance of small-tailed Han sheep was preliminarily discussed.

The results of the study showed that:① Using dozens of kilograms of explosives the signal can be detected at distances up to 200 km;②Active source has a certain degree of repeatability among different shots;③This paper presents the following shooting mode and signal detection method based on the similarity of different shots: In light of the similarity between the signals of big shot and small shot, this paper presents a cross-correlation method using signal from big shot signal with high SNR and small shot signal to detect weak small shot signal, the method can effectively detect the small shot signal and pick up the start time of phase, this method can help us make full use of past seismic exploration data records.

野外实验采用1次大当量激发和16次小当量激发，研究结果表明：①有可能利用数十公斤当量的炸药实现200km距离的探测；②在激发条件相同时，不同当量的激发波形滤波后存在一定的相似性；③依据人工震源可重复性采用以下的激发组合方式和处理方法能够有效提高信噪比：针对大当量激发与小当量激发波形的相似性，利用大当量激发的波形作模板与小当量激发的波形作相关，可判断台站是否接受到小当量激发的信号并检测其震相到时信息。
