查询词典 correlation analysis

The main calculation in the particle image matching algorithm is to have the two visual seriate images taken the cross-correlation arithmetic based on the fast fourier transform. This paper discusses the basic principle of the cross-correlation arithmetic in detail, discuss each stage of its produce and development and also discuss the thinking, the merit and the defect of each algorithm. On the base of all these discussing, we confirm our algorithm and realize it in programming with C++.

粒子图像的匹配算法的主要运算是将两连续的视频图像进行基于快速傅里叶变换的互相关运算，本文详细论述了相关算法的基本原理，它的产生和发展的各个阶段，各种算法的思路和优缺点，在此基础上确立了自己的算法并以C++编程实现。

Temporal and spatialcorrelation of Soil moisture under vertical direction was affected by some factor such asmeteorology, land use and fertilization measures. All siol moisture in different layers hastemporal and spatial correlation when soil moisture fluctuates of surface layer becausestability, but influence ability of each factor is not the same. For example, meteorologyhas most strong impact on temporal and spatial correlation of soil water content.

在气象条件较稳定的情况下，不同植被覆盖和不同施肥措施下各土层含水量之间都具有较强的时空相关性，随着气象条件波动加剧，各土层土壤含水量的时间相关性和空间相关性都降低；植被因素相对气象条件对各土层含水量的时间自相关性影响较小，而对各土层土壤含水量之间的空间相关性影响较大，裸地和农田各土层土壤含水量之间的空间相关性相对林地和草地较弱；不同的施肥水平都削弱了土壤各土层含水量的时空相关性。

Applying the grey correlation methods, this paper analyzed the correlation of slaking durability and granularity fractal characteristics of red bed weak rock as well as the experimental data of mineral and chemical component.

摘要采用灰色关联度法对红层软岩的粒度分形特征以及矿物、化学成分试验数据与其崩解性进行了关联分析。

There was a significant inverse correlation between sarcomere length and A/I (r=-0.686, P.05). 4 Relations of the skeletal muscle histological characteristics and meat quality The muscle fibre and the myofibrils diameter were thinner, the muscle fiber density was denser, the sarcomere length was longer and the meat color was redder. The A/I was bigger, the meat color was whiter, contrarily was redder. The right amount of fat content may improve the meat brightness. The muscle fiber diameter and the myofibrils diameter were the biggest factors to influence the skeletal muscle shearing force, their assumed the obvious linear correlation. The muscle fiber density influence on the shearing force was only inferior to the muscle fiber and myofibrils diameter. Mensurate the IFA from tectology angle may reflect in intramuscular fat content. However intramuscular fat was not enough to carry weight on the shearing force, it may mostly affected on the smack, but not the tenderness expression.

猪骨骼肌组织学特性与肉质性状的关系肌纤维和肌原纤维直径越小、肌纤维密度越大、肌节长度越长，肉色鲜红；肌节中暗带比例越大，肉色偏白，而明带比例大，肉色偏红；适量的脂肪含量可以改善肉的亮度；肌纤维直径和肌原纤维直径对骨骼肌剪切力的贡献率最大，呈明显的线性相关，肌纤维密度对剪切力的贡献率仅次与肌纤维和肌原纤维直径；从组织形态学角度测定肌内脂肪面积比一定程度上可以反映肌肉内的脂肪含量，而肌内脂肪对肌肉剪切力的贡献率比较微弱，对肉食用品质的影响可能更多表现在改善肉的风味，而不是嫩度的表达。

There was a positive correlation between each of them and MVD. VEGF expression was positively correlated with lymph node metastasis and C-erbB-2, negatively with ER, PR, PS2 status, thereas no statistical correlation between VEGF expression and age, tumor size, clinical stage.

实验还发现有淋巴结转移组VEGF mRNA水平明显高于无淋巴结转移组，有统计学显著差异（P.01），VEGF mRNA表达水平与ER、PR、Ps2表达呈负相关关系，三种方法测得VEGF表达水平均与C-erbB-2表达呈正相关关系，但却与肿瘤临床分期，患者年龄，肿瘤大小无关。

The results indicate that temperature has positive correlation with IFACR and TOI and RH show negative correlation.

结果表明，浸润时间和相对湿度跟平均腐蚀速率呈负相关；温度跟平均腐蚀速率呈正相关。

3Wood basic density had a significant, negative genetic correlation with tree volume and tracheid length, and had no significant correlation with tree height, diameter at breast height, ratio of length to width and ratio of cell wall to cavity.

3基本密度与树高、胸径、管胞长宽比、壁腔比无显著遗传相关；与材积、管胞长度有显著的负遗传相关。

And T.hamhtum had secondary auto-correlation in spatial distribution,but the spatial auto-correlation of quantity and sort of Trichoderma was low.

基于ArcGIS8.1的地统计学方法分析表明，成都平原土壤真菌种类和数量均具有一定的空间自相关特征。

In this paper,the possessed knowledge on study generalized correlation-immunity is introduced,including stream ciphers system,Booleam function in ciphers,divide-and-conquer attacks,ungraduated ruler of correlation-immune.

文章介绍了研究广义相关免疫函数应具备的知识，包括：流密码体制、密码学中的布尔函数、分别征服代数攻击、相关免疫的界定。

Results There were no sinificant difference in incidence of aneuploid and highs synithesis phase fraction, the size and distribution of AgNOR between unrecurrent and recurrent tumors, and there were sinificant difference between benign and malignant tumors, and there were singnificant differenct in the number and shape of AgNOR between the groups, and a linear positive correlation was observed between that obvious positive correlation was observed between highs SPF and number of AgNOR.

结果 异倍体率，高S期细胞比率率，AgNOR大小和分布在无复发与复发组间无显著差异，而良性与恶性肿瘤间有显著差异；AgNOR数目和形态各组间有显著差异；高SPF率与AgNOR均能反映其细胞增殖活性。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。
