Chaper 3 is general description of ADA encryption. Chapter 4 deals with the transform domain encryption. Includes the element of perfect and quasi-perfect transform domain encryption, and presents two type new schemes. Chapter 5 deals with asynchronous ADA encryption. Extends the general theory and model of asynchronous ADA scrambling, and introduces two type phase-distortion-free a synchronous ADA schemes. Chapter 6 is about new direction of ADA encryption. Includes TASI scrambling, transform domain dummy insertion scrambling, noise coving scrambling and other multi-dimension ADA scrambling, and proposes an adaptive dummy spectrum insertion asynchronous scrambling and a new adaptive noise-coving DFT scrambling algorithm. Chapter 7 is on permutation key. presents part results on permutation features, selecting criterion and constructing method. Chapter 8 introduces the hard and software design of a common ADA encryption/decryption system, and presents the experimental results on several proposed ADA encryption schemes.

Even if a creationist does accept afossil as transitional between two species, he or she may then insiston seeing other fossils intermediate between it and the first two.

即便有神创论者承认某种化石对应两个物种之间的过渡物种，他仍然可能要求见到在该过渡物种和原有的两个物种之间的化石遗迹。

In chapter two,two properties of Bak-Sneppen model:the self-organized criticality and punctuated equilibrium are introduced.

本文第二章主要是在Bak-Sneppen模型的基础上，讨论了Bak-Sneppen模型中的两个主要性质：自组织临界性和断续平衡性。

Cross rate is the rate two currencies without exchange rate calculated from two exchange rates which are related to the same currency.

交叉汇率是从两个与同一货币有关的汇率中计算出来的、本来没有汇率的两种货币之间的汇率。

To resolve this problem, we'll reel outwards drive across the bridge to the intermediate surface of variable-speed drive wheel with two wheels of processed into 30 °, the increase in friction with Groove, even if such a belt would not have had; the diameter of 6 mm, spin out to o-rubber belt changed out with Burr corn-cob o-shaped belt; crossing the bridge to another variable-speed drive belt pulley to roll out of the book, two rounds of the belt pulley turned into 1/2 inch, using chain drive sprocket, and fixed machinewe side wall to cross the bridge wheel seat side wall plate processing growth holes for adjust tension pulley and sprockets.

为解决这个问题，我们将分切机朝外传动面传动到中间过桥变速皮带轮的两轮加工成30°的带槽，增加摩擦力，这样皮带即使松了也不会打滑；直径6mm的O型橡胶皮带改成外面带毛刺的聚氨酯O型皮带；过桥变速皮带轮的另一个传动到出书辊的皮带轮，两轮改成1/2英寸的链轮，采用链条传动，再将固定在机器侧墙板的过桥轮座侧墙板孔加工成长孔，可任意调整皮带轮与链轮的松紧。

Later I saw a child-care book, above, said the baby's eyes does not look precisely because of two eyes do not like folding the corner of the eye, so the two eyes are not eyes look right in the middle of crack, which is strabismus, or cross-eye.

后来我看到一本育儿的书，上面说婴儿的眼睛看起来不正是因为两只眼睛眼角的褶皱不一样，所以看起来两个眼球不在眼裂的正中，也就是斜视或斗鸡眼。

The isothermally crystallized films of the low temperature fractions of the two PPEs possess the similar crystalline morphology, i. e., thinner and high content of cross-hatching lamellae. The main reason to create the different crystallization behavior between the two PPEs and their fractions was due to the different distribution of the copoymerized ethylene unit.

对于分级样品，PPE1和PPE2高温级份的结晶行为差别较大：PPE1的高温级份结晶时形成的片晶较厚并且交叉片晶的数量也较低，剪切时产生较多纤维晶；两个样品的低温级份结晶形态类似，即结晶时形成的交叉片晶的含量都较高，剪切产生纤维晶数量差不多。

The results show that the peak tension in the conductor of upper crossarm at suspension point exceeds the design value. Insulator rupture has no effect on tower component of upper crossarm, but it has significant influence on insulator tension of upper crossarm. The lower limit of longitudinal unbalanced tension of two and more than two bundle conductor is relatively small. Insulator rupture should be taken into account in the design for overhead transmission lines.

分析结果表明，上横担一组绝缘子破坏失效后，破坏档未破坏端导线的张力超过了技术规程中的设计值；导线的跌落对破坏档未破坏端的上横担绝缘子受力有较大的影响，而对上横担铁塔杆件没有明显的影响；考虑杆塔断线荷载时，应增大两分裂以上导线纵向不平衡张力的下限值；在架空送电线路的设计中应该考虑绝缘子断裂的荷载工况。

You shall not crossbreed different kinds of animals."'you shall not sow your field with two kinds of seed;"'neither shall there come upon on you a garment made of two kinds of material.
