A quick and correct forecast of tidal current when oil spill occurs is a key step in the forecast of oil spill. Based on the harmonic constant of tidal component of M2, S2, O1 and K1 in Lingshan Island, Laoshantou and Chaolian Island, and by using harmonic method, the thesis first conducts a current forecast in a single point, and then builds up a current field forecast in Jiaozhou Bay and its adjacent seas. The computed results match well with the actual situation. The method reduces greatly the time of real time current forecast by not using numerical stimulation, so it fit to the two requirements of quickness and correctness in oil spill forecast system.

迅速准确地预测出溢油发生时的潮流情况是溢油环境预测的根本保证，因此文中根据灵山岛、崂山头和朝连岛三处M2、S2，、O1和K1四个主要分潮的调和常数资料，采用调和的方法进行单点的潮流预报，进而建立了胶州湾及邻近海域的预报潮流场；该方法的潮流预报结果与实际情况吻合良好，且因避开了数值计算过程而大大减少了流场实时预报的机时，符合溢油应急预报系统所要求的准确与快速。

A key point in Short Time Fourier Transform is the choice of window function. Although rectangle window is regarded as the first choice because it's featured by integral harmonic to filter signals and by DC component, decaying DC component and frequency shift of signals cause great error to rectangle window STFT. In addition, transient signals contain rich information of faults, but the fixed time window of STFT fail to collect these information.

STFT 算法关键问题之一是窗函数的选择，矩形窗以滤除信号整数次谐波和直流分量的特点自然称为首选窗，但衰减直流分量和信号的频率偏移对矩形窗 STFT 造成了很大误差；其次，暂态信号中含有丰富的故障信息，傅立叶变换固定的频窗忽略了这些特征信息。

Results indicate that:(1) by using HANTS, the researchers could get the EVI/NDVI harmonic curves, the mean VIs and the amplitude of the harmonics which then were utilized in the identification of the cultivated land, and EVI appeared to be more precise, with the overall accuracies of 97.17% and 95.99% and Kappa coefficients of 0.7938 and 0.6518, respectively.(2) Multiple cropping index was extracted by counting the number of the curve's peak; and when the threshold of the peak value of the NDVI and EVI curves were set as 0.25 and 0.20, respectively, the fallow land could be well figured out.(3) From harmonic curves, some eigenvalues, such as time of the maximum growth rate, time of peak and the value of peak can be extracted, based on which the crop types can be primarily distinguished. And EVI still performed better than NDVI in this section.

结果显示：（1）利用傅立叶谐波变换得到的EVI和NDVI时间谱曲线的谐波余项及谐波振幅对耕地进行识别，从识别精度来看，EVI要优于NDVI，识别精度分别为97.17%和 95.99%，Kappa系数分别达到0.7938和0.6518；（2）通过计算时间序列曲线的波峰数能够提取耕地的复种指数，并且在EVI和NDVI曲线波峰阈值分别设为0.20和0.25时，休耕地能较为准确地被识别出来；（3）通过提取作物生长期内曲线的VI最大增长速率时间点以及峰值时间点等信息，作物种类能被初步识别，并且EVI较NDVI具有更强的识别能力。

This article is based on the research of Mr. Li Yinghai"s monograph the modes of Music of the Han nationality and their harmony, his music composition and a series of his vocal music works, piano works. From the structure of the chord, the harmonic progression, the modes and tonality, texture composition style, the style of dealing with the skill and technique of national music sound simulation, etc. the author expounds Mr. Li Yinghai"s great achievement and his precious experience on academic research and application on national mode harmony in detail.1. Music composition should regard nationalitys traditional music as foundation, and at the same time use European traditional skill and technique of music composition for reference, seek the harmony of traditional skill and technique, modern idea and national style. Only in this way could we promote research of the national music theory and creation of the national music.2. Theory stems from practice, guides practice again at the same time. And theory is developing, perfecting constantly in practice.

文章以黎英海先生的理论专著《汉族调式及其和声》以及他创作、改编的一系列声乐作品、钢琴作品为研究对象，从和弦结构、和声进行、调式调性、织体写法、间音处理手法、民族音乐音色模拟技法等方面详细论述了黎英海先生在民族调式和声理论的研究与应用上取得的丰硕成果与宝贵经验及其给我们的两点启示：1、音乐创作应以民族传统音乐为根基，以欧洲传统作曲技法为借鉴，努力探求音乐创作中传统技法、现代理念与民族风格的和谐统一，以此推动民族音乐理论的研究与民族音乐的创作。2、理论来源于实践，同时又指导实践，并在实践中不断发展、完善。

There are two types of horses that compete in harness racing: one is the pacing horse, which moves both legs on one side of its body at the same time, and the other is the trotting horse, whose left front and right rear leg move forward at the same time, then right front and left rear leg move together.
