提取

This paper expounds a methodology which employs spectral reflectance, geometric property and texture feature of a given target synergistically under the framework of feature-level information fusion.

利用多光谱遥感影像进行地物目标识别和提取已经有20多年的研究历史，取得了一定的研究成果，但是已有的地物目标识别提取方法所用到的地物目标的特征信息还比较单一，因此地物目标的识别率和提取效果还不够理想。

Comparatively sundried flowers are more suitable to be extracted as an industrial material although the concrete yield of fresh flowers is a little more. At the same time the experiment process fully proves the selectivity of SFE-CO2. Low temperature and low pressure are suitable to extract concrete from natural flavor and fragrance;(2) The materials prepared to extract rutin are the flowers that are gotten rid of concrete by SFE-CO2. The extraction methods include the SFE-CO2 modified by alcohol, the method of hot alkali-precipitate with acid, and alkaly dissolving and acid subsiding combined with microwave or ultrasonic.

66%；产品运用GC-MS做了鉴定；虽然鲜花浸膏产率较高，但干槐花的物料状态更适合工业生产；同时实验过程充分体现了SFE-CO2的选择性，低温低压条件适合香料的SFE-CO2；(2)以超临界CO2(Supercritical CO2，简称SC-CO2)萃取过浸膏的干槐花为原料，运用夹带剂修饰的SFE-CO2、超声或微波或直接加热的碱溶酸沉法提取中药--芸香甙，相比之下，夹带剂修饰的SFE-CO2和超声辅助的碱溶酸沉法提取效果较好，芸香甙提取率分别为2。

In the mobile communication system, the intermediate frequency signal results in the characteristic value is took the appraisal signal quality one kind of standard, how this topic main research is withdraws the intermediate frequency signal the characteristic value,as well as withdraws in the method in each kind to select superiorly withdraws the intermediate frequency signal characteristic value the method.

在移动通信系统中，中频信号得特征值是作为评估信号质量的一种标准，本课题主要研究的是如何来提取中频信号的特征值，以及在各种提取方法中选出最优的提取中频信号特征值的方法。

In this way, the parameters of several models under the same bias condition can be extracted synchronously.

在可靠性模型参数提取方面，本论文提出了一种多目标全域优化提取的参数提取方式。

The main results were as follows:①The genomic DNA extraction method from TCK/TCT teliospore was established, which include cell wall lysis of teliospore by alkali solution, destroying teliospore cell wall for releasing nucleic acid from cytoplasma membrain and elimination of the PCR inhibitors such as pigments or polyphenols component.

论文主要研究结果如下：①优化了碱裂解法破冬孢子外壁-CTAB破坏原生质体，释放核酸-微量DNA过滤柱去除色素、多酚等PCR抑制物质的TCK/TCT冬孢子提取方法，排除了冬孢子细胞壁难破DNA难以提取，三甲胺、色素等PCR抑制物质导致假阴性的难题，采用此方法提取的腥黑穗菌DNA完全适用于PCR扩增。

Features of each face image are extracted by using the wavelet transformation and the tensor principal component analysis algorithm. Weights of the features' elements are then determined using PSO according to the right clustering rate of each element, so that the object to extract the key features of the faces can be realized.

采用小波变换和张量主成分分析方法对人脸图像进行特征提取，利用PSO对提取的特征进行加权处理，根据特征的每一维元素的聚类正确率进行优化选择，从而达到对人脸提取关键性特征的目的。

Some preparation methods of galanthanime including extraction and organic synthesis were summarized, such as extraction from narcissus, galanthus woronawii losink, and lycoris radiate and countereurrent chromatography refining, and enzymatic extraction from hyacinths orientalis, as well as the organic synthesis using 3,4-dimethoxybenzaldehyde, methyl 3,4,5-trihydroxybenzoate, isovanilin and tyramine as raw material.

概述了加兰他敏从黄水仙、沃氏雪花莲中提取、石蒜中提取及逆流色谱法精制、喇叭水仙酶法中提取的方法、工艺；以3，4-二甲氧基苯甲醛、3，4，5-三羟基苯甲酸甲酯和异香草醛和酪胺为起始原料合成加兰他敏的方法。

The results show that the DNA extraction method based on Sambrooks method is relatively simple and easy to obtain high quality genomic DNA from freshwater unionid species.

结果表明，基于Sambrook的方法改进的DNA提取方法不仅步骤简单，而且提取的基因组DNA分子大、质量高，适合淡水蚌类基因组DNA的大规模提取。

Feeling-of-knowing judgment refers to the mode of expressing knowledge about unrecalled information —although we don't possess enough information to recall the item, it is possible to indicate whether we could recognize it.

知晓感（Feeling-of-knowing，FOK）是元记忆监测的核心指标，它是指在记忆提取失败之后，相信某信息能从记忆中提取出来，但现在又提取不出来的一种心理状态。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
