For such complex and composite systems as analogue and digital systems, electronic and mechanical systems, the Ptolemy II attain purposes with heterogeneously hierarchical ideology, in other words, actors and model of computation at the same level stand for a behavior of the system, and these components at this level can be converted into a composite actor that stands for another behavior of the system under the control of different models of computation at upper level with other actors. In this way, the system may be structured hierarchically.

对于复杂的混合系统，如模拟与数字系统，电子与机械系统，Ptolemy II采用层次异构的思想实现，即同层的角色和计算模型表示系统的一种行为，而这一层组件又可转变为一个复合角色，在上一层与其它角色在不同的计算模型控制下表示系统的另一种行为，从而实现系统的层次构架。

It was difficult to see what she was like for she was wearing two frocks, one on top of the other, and had a large red scarf wound round and round her as well. She looked like some shapeless bundle of clothing trudging uphill on a pair of hobnailed boots.

可要说出她那模样就不太容易了，因为她穿着两件衣服，一件套着另一件；她的脖子还围着一条红色的棉线大围巾；她的一双脚被穿着的钉鞋给遮住了，所以这个小东西在熬着酷热吃力地往上爬山的时候，那模样是看不清楚的。

The efforts that have been made to explain optical phenomena by means of the hypothesis of a medium having the same physical character as an elastic solid body led, in the first instance, to the understanding of a concrete example of a medium which can transmit transverse vibrations ,and at a later stage to the definite conclusion that there is no luminiferous medium having the physical character assumed in the hypothesis.

为了解释光学现象，人们曾试图假定有一种具有与弹性固体相同的物理性质的介质。这种子尝试的结果，最初曾使人们了解到一种能传输横向振动的具有上述假定所以认为的那种物理性质的发光介质。科技文章的另一特点是大量使用复合词与缩略词，复合词从过去的双词组合发展到多词组合；缩略词趋向于任意构词，例如某一篇论文的作者可以就仅在该文中使用的术语组成缩略词，这给翻译工作带来一定的困难。例如

It's a perceptual ability I call mindsight," says Daniel Siegel, UCLA psychiatrist and author of The Mindful Brain."It allows your brain to create a map of another person's internal state.

加州大学洛杉矶分院心理学家、《思考大脑》一书的作者Daniel Siegel说&这是一种我称之为&智视&的感知力，这一能力使大脑&绘制出&反映另一个人内心状态的地图&

A hedge forms the division between her land and mine.;相关词条:separatrix;dividing line;demarcation line;borderline;PL

同一屏幕上，两幅图象的可见部分有一分界线，移动这一分界线，把一幅图象逐渐抹掉，逐渐显示另一幅图象。

The steep bits that take away our breath, the stony bits that make our feet ache so, the hot shadeless stretches that make us feel so exhausted, the rushing rivers that we have to pass through-Jesus has gone through it all before us.

这一程使我们心慌意乱，那一程使我们筋疲力尽，另一程使我们乾渴得舌贴牙床，又一程使我们喘不过气来－其实以前主都尝过、走过。

The steep bits that take away our breath, the stony bits that make our feet ache so, the hot shadeless stretches that make us feel so exhausted, the rushing rivers that we have to pass through ━ Jesus has gone through it all before us.

这一程使我们心慌意乱，那一程使我们筋疲力尽，另一程使我们干渴得舌贴牙床，又一程使我们喘不过气来━其实以前主都尝过、走过。

It is not only the eating of them, but the finding: the fluttering up there and hopping from branch to branch, the sidling out to the extreme end of the bough, and the inward chuckling when a friend lets his acorn drop tip-tap from bough to bough.

不光因为有得吃，这欢乐也来自找寻果实：它们拍打着翅膀飞上树梢，轻快地从一根枝条跳到另一，侧身行至枝枉的最边缘。当一只乌鸦掉落的橡果噼噼啪啪从一根根树枝上弹落下来时，会引起伙伴们一阵咯咯暗笑。

The encapsulated TiO〓 particles by polymer were obtained with soapless emulsion polymerization of methyl methacrylate in water in the presence of the pretreated TiO〓 particles.

一种是用偶联剂钛酸丁酯对亲水性TiO〓粒子进行预处理，钛酸丁酯与TiO〓表面羟基反应，交联到TiO〓粒子表面，使TiO〓粒子表面由亲水性转变为憎水性，改善无机粉体与有机单体的亲合性，再进行TiO〓存在下甲基丙烯酸甲酯的无皂乳液聚合，即可得到TiO〓-PMMA复合粒子：另一种方法是用表面活性剂对TiO〓进行预处理，再进行TiO〓粒子存在下甲基丙烯酸甲酯的无皂乳液聚合，TiO〓粒子表面可形成一层均匀的聚合物膜，提出了包覆机理，指出单体在无机粉体表面发生聚合的关键是预先在粒子表面形成聚合场所，即吸附一层表面活性剂。

In another embodiment, a tamper resistant informational article is provided by creating a base having an upper surface and a lower surface with an elongated metal core having extruded therearound a resinous plastic material.

在另一实施例中，通过形成一个具有一上表面和一下表面的基部来提供一种防篡改信息物品，该基部带有一细长的金属内芯，该金属内芯包围着树脂塑性材料挤压。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
