This paper introduces eight methods of tlme-frequency analysis, such as Hilbert transform, Hilbert-Huang transform, sine curve fitting, Ricker wavelet matching, short time Fourier transform, wavelet transform, S transform and Cohen methods, This paper explains the merits and defects of those methods from the time resolution, frequency resolution and the adaptive ability of multi-frequency signals.

本文介绍了Hilbert变换、Hilbert—Huang变换、正弦曲线拟合、雷克子波匹配、短时傅立叶变换、小波变换、S变换以及Cohen娄这八种方法，并从时间分辨率、频率分辨率，以及对多频率成份信号适应能力等各方面阐述了各种方法的优缺点，对其中的一些方法结合了理论记录进行了试算，进一步阐述了这些方法的长处和不足之处。

A larger initial Cobb angle (odds ratio = 4.6), a lower Risser grade (odds ratio = 4.7), premenarchal status (odds ratio = 2.5), osteopenia in the femoral neck of the hip on the side of the concavity (odds ratio = 2.3), and a younger age at the time of diagnosis (odds ratio = 2.1) were identified as risk factors in predicting curve progression.

初次大的Cobb角（优势比＝4.6）、低的Risser级（优势比＝4.7）、月经初潮前（优势比＝2.5）、凹侧髋的股骨颈骨质减少（优势比＝2.3）和诊断时年龄小（优势比＝2.1）是预测侧凸进展的危险因子。

This study included 204 patients with AIS（36 males,168 females）,selected from December 2006 to April 2008,with mean age 15.0 years old,mean Cobb angle 50.1°,mean Risser sign 3.4,mean main curve span 6.8 vertebrae and mean apical rotation 2.0°.Preoperative radiographs included a standing posteroanterior film and supine maximal voluntary side bending films of the spine.

Grain quality affected by N application and plant density could directly influence malting quality. Grain protein content was negatively correlated to steeping degree and steeping rate, and positively related to saccharogenic power. The relationship of grain protein content to a -Amino-nitrogen content and kolbach index could be expressed with a quadratic curve equation, respectively. The greatest decomposition rate of protein might be achieved when grain protein content was 11-12%.

施氮量、氮肥运筹比例和密度对籽粒品质的影响直接影响着麦芽品质，籽粒蛋白质含量下降，浸麦度和浸出率上升，糖化力下降，籽粒蛋白质含量和库值、氨基氮呈二次曲线关系，籽粒蛋白质含量在11%一12%时，其蛋白质分解速率最快，麦芽总氮与籽粒总氮呈极显著的正相关关系，在麦芽的生产过程中氮的消耗率与籽粒总氮为极显著的负相关关系。
