多步的

This paper offered two pieces of practical arithmetic about encrypting of data by analyzing theory based on encrypting of data.

通过分析基于数据的加密原理，本文给出了两个较实用的数据加密算法：公钥加密和多步加密算法。

Lanczos method is optimized in LDLT triangular decomposition 、 vector reorthogonalization and result judgement. At the same time a new method of result judgement is brought forward, and named mode compare method. The example proves the optimized results of the method.

在LDLT三角分解、向量重正交及丢根判断等步骤上，对Lanczos算法进行了多步优化，同时提出了新的丢根判断方法——模态比较法，并给出算例对优化效果进行了验证。

More than 95% purity achieved after removal erythrocyte, nonparenchymal cells and dead cells with multi-step low-speed centrifugalization.

通过多步低速离心可去除红细胞、其他非实质细胞和死亡的肝细胞，其纯度可达95%以上。

In theory, this kind of interferometer can divide the parasitic interferential signal, meanwhile, it has nonlinear error.

在计算过程中，对时域采样数值进行加权，然后采用多步移相算法进行位相计算，可以有效地抑制谐波误差的影响。

Two kinds of cross-linked polyacrylate latices with relatively narrow distribution of particle diameters, which are abbreviated to P and P/P, were synthesized by seeded emulsion co-polymerization, respectively. Butyl acrylate and 2-ethylhexy! acrylate were used as comonomers of ACR core, styrene and methyl methacrylate were employed as comonomers of ACR shell, and 1,4-butanediol diacrylate was used as cross-linking agent.

采用丙烯酸丁酯和丙烯酸2-乙基己酯(2-EHA)为核层单体、苯乙烯和甲基丙烯酸甲酯为壳层单体、1，4-丁二醇二丙烯酸酯为交联剂，通过多步种子乳液聚合方法合成了P、P／P两种具有窄粒径分布的共聚丙烯酸酯胶乳。

Fourteen unreported N-substituted piperidin-4-one oxime ethers derivatives were synthesized withsubstituted benzylamines or phenethylamine as raw materials via a series of Michael addition, Dieckmann condensation, hydrolysis decarboxylation reactions, oximation a...

以取代苄胺或苯乙胺为起始原料，依次经Michael加成，Dieckmann缩合，水解脱羧，肟化和醚化等多步反应合成了14个未见文献报道的N-取代哌啶酮肟醚衍生物。

The pyridinium salts was transformed by the base to 1-hydroxy or 3-hydroxy-quinolizinylides, which undergo 1,3-dipolar cycloadditionreaction with alkenes,and then aromatizated to cycl[3,3,2]azinone in thepresence of oxidant.

实验证明，这是一个连续进行的多步反应：2-羰基吡啶鎓盐在反应中先生成1-羟基或3-羟基喹嗪叶立德，然后与烯烃起1，3—偶极加成反应，最后在氧化剂作用下脱氢芳构化而生成Cycl[3，3，2]azinone。

As those with more experience of ballots could have told them: voting is the easy part.

对投票有更多了解的人也许会说：投票不过是万里长征第一步罢了。

By the 1930s some liberals moved much further to the left and turned to secular humanism as reflected in their 1933 manifesto repudiating the existence of God, immortality, and the supernatural in general, and substituted faith in man and his capabilities.

有些自由派提出了1930多步左右转向世俗人文主义(反映在其1933年宣言否定了存在上帝，不死、鬼神，以及一般人的信念取代其工作能力)。

We know that in our busy and frenzied lives, everyone desperately needs to slow down to take a few breathers.

我們知道每一個人都渴望在這個繁忙多變的生活中放慢腳步，找個空檔喘口氣。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
