查询词典 binary

Because more control can be obtained via binary pixelated arrays of metal pixels, as used on the National Ignition Facility to precompensate for the spatial gain variation of large glass amplifiers, we intend to adopt the binary mask method to spatially shape the Gaussian laser beam in "ShenGuang II" laser driver system.

The yield of conversion and reaction rate were investigated under different reaction temperature, reactant ratio and catalyst amount through conditional experiment, and best conditions were confirmed, which was 75℃, the ratio of 1:4 for binary acid to ethanol and the amount of silicotungstic acid was 2% of mixing binary acid quality.

通过条件试验，分别考察了在不同的温度、投料比、催化剂用量情况下酯化反应的转化率和反应速率，最终确定了该反应的最佳反应条件：温度75℃，酸醇比为1：4，催化剂用量为混合二元酸质量的2%。

The open reading frame of Spinacia oleracea Betaine Aldehyde Dehydrogenase was retrieved from Spinacia oleracea and inserted into the Agrobacterium tumefaciens binary vector pBin438, which was driven by CaMV35S promoter, and produced the new binary vector pBSB. A. tumefaciens LBA4404 carrying this plasmid was used in genetic transformation of plants. Forty-five primary transgenic plants were detected by PCR and verified by the Southern blotting from 65 regenerated plants, of which 27 transgenic plants had only one copy of T-DNA.

然后，提出了一种基于双向关系的优对关联关系的挖掘算法。

In order to extend the effect and security of image encryption algorithm.An image encryption algorithm is presented based on three-dimension chaotic system and bit-computation.The permutation sequences and binary sequences are generated using three-dimension chaotic system.Firstly,the image is pretreated using chaotic system and permutation transformation,then the pixel's gray value's bit sequences are permuted using the permutation sequences generated before,at last,the pixel's gray value's bit sequences are computed by using XOR operating and the binary sequences.

为了改进图像加密算法的安全性和效率，提出了一种基于三维混沌系统和位运算的数字图像加密算法，利用三维混沌序列的坐标分量分别产生置换序列和二值序列，在对待加密图像进行预处理的基础上，先应用混沌置换序列对预处理的结果图像进行基于灰度值位序列的置换操作，然后再应用产生的二值序列对结果图像的灰度值位序列进行位异或加密运算。

Good effect is obtained. The application of derivative sign binary algorithm in interference fringe skeletonizing overcomes the difficulty of threshold picking in ordinary binary methods.

导数符号二值图法在提取干涉条纹中心过程中的运用，克服了普通二值化方法中阈值难以选取的问题，提高了测量的精确度。

Furthermore, Binary stars have been neglected in most studies of the integrated light of the stellar populations with the EPS methods. However in real clusters and galaxies over 50% stars are in binaries, and binary interaction can result in some important classes of objects, such as blue straggles and subdwarf B stars (sdB, also referred as extreme horizontal branch ) which contribute significantly to the integrated light.

另外，多数演化星族合成模型在对星族进行研究时没有考虑双星作用，而在真实星团或星系中50％以上的恒星属于双星系统，双星相互作用可以产生一些重要天体，例如蓝离散星和B型亚矮星，而这类天体对积分光谱有重要影响，因此本论文研究目的之二就是在演化星族合成模型中考虑双星作用。

Upon this foundation,a corpus-based algorithm was designed and implemented to acquire and filter binary semantic pattern rules automatically. In the algorithm,a data mining method for cross-level association rules is adopted,which is guided by metarule,to find the semantic laws of word combinations in Chinese phrase corpus. Then statistic results are used to filter the findings. In the end,the remains are transformed into binary semantic pattern rules.

在此基础上，本文设计并实现了基于语料库的二元语义模式规则自动挖掘和优选算法，该算法先采用数据挖掘中元规则制导的交叉层关联规则挖掘方法，自动发现汉语短语熟语料库中词语两两组合的语义规律，再根据统计结果自动优选后转换生成候选二元语义模式规则集。

For this reason, the author used mid-value filtering method for diminishing the pattern noise, the binary-image transformation method by selecting variable threshold value, and the extraction method of the central line for full-field binary-image.

为此作者使用中值滤波法对图像噪声进行抑制，利用可变阈值对图像进行二值化，实现了二值图像条纹灰度中心线的自动检出。

Traversals work with any binary tree, not just with binary search trees.

下一步，insert必须先确定新节点插入的位置。
