查询词典 decomposition

Numerical simulation results show that the fluid flow in Lost Foam Process was different from that in an ordinary green sand mold, the molten metal flow forwards in a circular-arc shape from the ingate, meanwhile, the nature of the gating system influenced the filling process notably. As the polystyrene pattern decomposition has a strong quenching effect on the flowing metal fornt, a high temperature gradient was formed at the flowing metal front, this resulted in the dropping of temperature of the metal to the liquidus temperature quickly and decreased the flowability of molten metal, the temperature distribution in the metal behind, however, was even. The properties of the pattern and the coating affected the temperature distribution remarkably.

从内浇口开始，金属液呈放射状均匀向前充填，同时浇注系统性质显著影响金属液充型过程的流场；由于聚苯乙烯模样气化吸热对金属液的激冷作用，在金属液流端部区域产生很大的温度梯度，使得端部区域金属液很快降至液相线温度，降低了金属液的充型能力，而后续金属液中温度分布则比较均匀，模样性能、涂料性能显著影响这一温度分布特点。

Vacuum was satisfied to the requirement of fresh-cut taro package and benefit to reduce water loss and to inhibit browning. The treatment of insufflate fresh-cut broccoli with 20mg·L-1 6-BA could delay chlorophyll reduction, inhibit ion leakage increasing and slow down the process of senescence. Fresh-cut broccoli packed with the atmosphere combination of 2.5%O2+7%CO2+90.5%N2 had high Vc and high chlorophyll content, and the senescence of the products was delayed certainly. The gas mixture of 5%O2+ 2%CO2+93%N2 could reduce the rate of respiration, chlorophyll decomposition, membrane breakdown and tissue senescence of pakchoi.

真空包装适合鲜切芋头，降低贮藏中鲜切芋头的水分损失，抑制鲜切芋头褐变发生；用20mg·L~(-1)6-BA喷洒鲜切青花菜可推迟叶绿素降解，抑制相对电导率的增加，延缓了衰老；2.5％O_2+7％CO_2+90.5％N_2MAP包装的鲜切青花菜Vc含量较高，叶绿素荧光值也较大，明显延缓了鲜切青花菜的衰老：5％O_2+2％CO_2+93％N_2混合气体抑制了青菜的呼吸作用，降低了叶绿素降解速度，减缓了细胞膜损伤及组织衰老程度。

Use Matlab7.3 development of the use of integral wavelet transform, the image is three decomposition and reconstruction of the way Sequence, a detailed report of the experiment, the results of screenshots and demo, the directory contains procedures to use the images of all documents.

详细说明：使用Matlab7.3开发的使用整数小波变换对图像进行3级分解和重构的程序，具有详细的实验报告，和演示结果截图，目录下包含程序中用到的图像等所有文件。

Followed by the decomposition phase is optimal feature subset selection, in which the optimal feature subset acquired the best divergence is obtained according to interclass/intraclass distance of the training samples. This procedure is implemented by a Genetic Algorithm, with each possible feature subset encoded as chromosome. Fitness scores in GA are calculated and evaluated based on Jeffries-Matusita distance of the selected training samples.

然后，对这些线性光谱特征利用遗传算法结合训练样本计算类内/类间距离搜索最优分类子集，其具体染色体编码取可能的特征号，适应度函数基于样本平均Jeffries-Matusita距离计算。

The intercalation ultraviolet absorption material begins combustion decomposition of interlamination negative ions at around 425 DEG C, and reaches peak temperature of exothermic peak thereof at the temperature of 478 DEG C, thus having strong thermal stability and being an excellent light and heat stabilizer.

该材料在约425℃左右才开始层间阴离子的燃烧分解，478℃达到放热峰的峰值温度，具有很强的热稳定性能，是一种优良的光热稳定剂。

Aiming at the mode mixing problem caused by intermittency signal in the sifting process of empirical mode decomposition,a new solution is presented.

针对在经验模态分解筛选过程中间断信号引起的模态混叠问题，提出了一种新的解决方法。

Invariability of the rate law and activation energy of the decomposition on doping suggests that the complex behavior is not due to a change of mechanism.

不变性率法和活化能分解掺杂认为，复杂的行为，是不是因为要改机制。

Owing to the approximate and detail coefficients at each level after decomposition using undecimated wavelet transform have the same length as the original signal, the transform can possess time invariant property and retain more characteristics in time domain, and therefore improve the effect of denoising.

由于非降采样小波分解后的各层系数和原始信号的长度均相同，因此在具备平移不变性的同时还能保留更多的时域信息，从而可以提高信号的降噪效果。
