This essay compares the advantages of traditional museum education with internet museum education. No matter which one is better, the modern museum education should catch up with the world and combine all resources to reach the goals of culture and thought transference and education share. Nowadays, it has become a world trend to put an emphasis on resource integration.

本文试图透过比较的方式来阐述传统博物馆教育以及网路博物馆教育的优缺点；不过，不论何者较优，在二十一世纪的今天，强调资源整合已经是一种世界性的趋势，博物馆也不例外，只有把不同形式的博物馆教育资源结合起来，并强调与世界接轨，达到实现信息、传递文化与教育共享的目标，这样才能真正发挥出博物馆的教育功能。

The algorithm tracks the changing rate of each coordinate transformation parameter through Kalman filter to facilitate better prediction of the initial searching point. More importantly, the powers of the noise models of the Kalman filter are effectively estimated online rather than making artificial assumptions on their values. The algorithm can hence adapt to various target motions and searching precisions in a real-time manner without any manual intervention.

该算法通过对坐标变换参数的变化率进行Kalman滤波来更好地预测初始搜索点；更重要的是，该算法有效地在线估计Kalman滤波器中的模型噪声功率，而非先验地对它们的取值做出假设，因而能够在没有任何人工干预的情况下动态地根据不同的目标运动状况和搜索精度进行实时调整。

The following results are made from this research: Assessing data quality and band combination of different bands in line with geo-target features in desertification areas, and determining basic bands for desertification monitoring. And understanding and studying the spectral features and variation rules of geo-targets in the experimental area, raising that it is the basis of geo-targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo-targets, realizing that in a great extent spectral-integrated-form-based classification method can remove the phenomenon of "different spectrum with same objects" resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo-target with similar spectral forms and much different values of whole reflectionratio. It is suggested that "red edge" range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel-based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. The remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed.

研究结果如下：首先针对荒漠化地区的地物特征，对高光谱数据不同波段的数据质量、波段组合进行了评价，提出了适用于荒漠化监测的基本波段选择集；初步了解和掌握了研究地区的地物光谱特性及变异规律，进一步明确了掌握地物光谱特征和变异规律是用成像光谱仪数据提取地物信息的基础；发现了基于光谱整体形状的分类方法在很大程度上能够消除由于传感器、地物目标观测方向之间的角度变化引起的反射率曲线整体平移的"同物异谱"现象，对于谱形相似而整体反射率的值相差较大的两类地物，通过引入均值和方差图像参与分类得到解决；研究还表明在植被"红边"范围内的波段是进行荒漠化监测的主要特征波段，这些波段与植被生物量和盖度都有密切的关系，是开展精细植被分类研究和植被定量反演的重要基础；像元的导数光谱分析可以消除土壤背景的影响，是进行植被生物量和盖度定量反演的有力工具；建立了荒漠化监测主要评价因子的定量反演模型，并分析了模型的适用性。

A major goal in this field is to identify drug-induced molecular changes and their effects on brain function.
