抽取

As there are only six parents in the diallel crossing. and one cross combination for genetic effect analyzing, and the datum from the number of regenerating didn't submit to the normal distribution formula even when they were transferred, there may be some aberrancy in the result of this character. Therefore, more experiments and larger samples are needful further to conform, improve or correct this research results later.

7本研究双列分析的亲本仅为6个，世代的基因效应分析也仅只有1个组合，可能导致统计分析结果偏颇，还由于性状胚性愈伤组织绿苗再生数资料经转换后仍不能遵从正态分布，也会使得该性状的分析结果可能有偏差，今后需要用更多的试验和抽取更大的样本进行分析研究，进一步证实、完善或纠正本试验结果。

Methods Two hundred and ninety seven middle-aged and aged females were sampled randomly from the cases who were examined in the bone mineral density measurement department of The Second Affiliated Hospital of Nanchang University from January 2004 to January 2006, and their age, stature and body weight were recorded exactly. The BMD of lumbar (L2~4), femoral neck, Ward's and great trochanter was measured by dual energy X-ray absorptiometer, then statistically analyzed.

Through analyzing the features and performances of CIC filters,HB filters and multiphase-filter,we combine them with decimators and decimate the A/D data,thus reducing the digital signal rate and the load of DSP when processing the base band signal.

通过分析CIC滤波器、HB滤波器和多相滤波器的特点和性能，将它们与抽取器相结合，对A/D转换后的数据进行抽取，降低了信号采样率，减轻了后续DSP处理基带信号的压力。

The Open domain Question Answering system is composed of five parts,that is,question classification,question expansion,search engine,answer extraction and answer selection.

开放域问答系统通常包括问题分类、问题扩展、搜索引擎、答案抽取和答案选择五个主要部分。问题分类在问答系统中起着很重要的作用，它的准确性直接影响到最终抽取的答案的准确性。
