可提取的

Data mining, known as Knowledge Discovery in Databases, is defined as the nontrivial extraction of implicit, previously unknown, and potentially useful information from a great volume of data accumulations. It uses machine learning, statistical and visualization techniques to discover and present knowledge in a form being easily comprehensible to humans. Data mining is an advanced data processing technique.

数据挖掘是在数据和数据库急剧膨胀的背景下，为解决"人们被数据淹没，但却饥饿于知识"这种困境而产生的，也是数据库技术、人工智能技术、统计技术、可视化技术等发展的结果，其目的就是从大量的、不完全的、有噪音的、模糊的数据中提取出隐含在其中的潜在有用的可信、新颖并能被人理解的信息和知识，它是一种高级的数据处理过程。

The results showed that the addition of alcoholate increased the elution recovery of phenolic acids on resins in supercritical CO2. The infrared spectroscopy was used to study the interaction between solute and solvent molecules in supercritical fluid. The hydrogen bond between alcoholate entrainer and phenolic acid was the main factor to increase the ability of supercritical elution. The results appeared that salvianolic acids could be extracted by supercritical carbon dioxide with ethanol as entrainer.

结果表明：醇类夹带剂的加入能大大提高树脂上酚酸类化合物的超临界洗脱率；通过红外光谱技术研究了超临界流体中分子间的相互作用与超临界洗脱过程的关系，认为醇类夹带剂与酚酸类化合物的氢键作用是提高酚酸类化合物洗脱率的主要因素；以乙醇为夹带剂的超临界CO2洗脱可应用于丹参酚酸的提取。

A kind of visual prediction and analysis framework of the execution time of real-time software based on program flowchart is proposed in the paper. The key issues of implementing the framework are discussed in detail, including creating the mapping between intermediate code segment and statement line of source code, retrieving the time of any given program segment from the perspective of CPU cycles of goal machine instruct, calculating CPU cycles of statement lines of source code, point-to-point WCETC (worst case execution time calculated) analysis algorithm based on program flowchart, and transforming CPU cycle into physical time.

In China, the need of lanoline is 2500—3000 tons, and many of them need to be import, but if take this method, the extraction rate can be increased from 25% to 85%, and the rest 15% can also be produced to be the popular compound potash around the world.

在我国，羊毛脂的需求量为2500吨――3000吨，大量的羊毛脂需要进口，而采用&一步萃取羊毛脂&从以前的提取率25％提升到85％，所剩的15％羊毛渣土可制成世界上抢手的复合钾肥。

This method,on one hand extractes the most efficient low features for lipreading,on the other hand,selectes features reasonably to improve their distinguishability.With 42-dimensional two-level visual features can get 77.8% rate of lip movement contents recognition for speaker-dependent cases.

此方法一方面提取了唇读的最有效的低级语义特征，另一方面更加合理地选择利用了特征的有效可区分性，使得用42维二级视觉特征，对特定人的唇动内容识别正确率达到77.8%。

By using high-resolution reference data to identify accurate GCPs, considering the spacecraft attitude deviations which TBUS can't supply, and adjusting the epoch time and ephemeris data at the criteria of constraint LeastMean-Square-Error, the geolocation accuracy of navigation for AVHRR data can be improved greatly.

由于采用具有足够定位精度的高分辨率参考图象以提取高精度的地面控制点，考虑了TBUS轨道报所不能提供的卫星姿态偏差，对历元时刻和卫星轨道根数进行有约束条件的参数最优调整，可使整条轨道大范围内的AVHRR导航定位精度有较大提高。
