在叙述了从不同的前驱体制备功能性的 T8方法基础上，介绍了从 T8大分子单体出发制备的无机/有机聚合物纳米复合材料在光固化树脂、耐热阻燃材料、多孔材料、改性高分子材料等领域的应用。

With long term research professor Lin and his fellow men develop theories of "mannikin analogy"、" tissue-equivalent"、"atom、molecule、big molecule design"、" technology of simulate enzyme"、" technology of inherit templet"," quasi-element equivalent method" and "light element substitute method".

经过多年的研究，林教授与其同仁创建了&人体模型的相似性原理&、&人体组织等效性的判别及测试方法&、组织等效材料的&原子、分子、大分子层次设计原理&。用仿生工程模拟酶技术和遗传模板技术成功研究出体内外能量传递和分布辐射、超声、微波、热力学、力学及复合等效的新型仿生材料。这些材料按照人体组织相应的基本元素组成，按照&准元素等效&和&轻元素替代法&避免金属元素的谱线干扰，在医疗照射能谱范围内（60KeV-20000KeV），组织等效性误差控制在5%以内。

Recall that "the waterish stuff" abbreviates an appropriate cluster of descriptions of the superficial properties of water by which it is commonly identified by competent users of the term, something like "the stuff that falls from the sky, fills the oceans, is odourless and colourless, is essential for life, is called 'water' by experts ..., or which satisfies enough of the foregoing."

回顾一下&这些水性材料&的简写，这简写的是：&材料，来自天空、汇集在江海，无色无味，对生命来说不可或缺，被专家称为『水』，……，或足以满足前述的东西&，这些是这个语词使用者通常都认同的水所表现出来的属性，而这些属性的一系列描述的简写，就是&这些『the』水性材料&。

Examples of illegal material include child pornography; libel; material that infringes any intellectual property right; and material that specifically advocates, solicits or abets illegal activity.

非法材料的例子包括儿童色情制品；诽谤；材料，侵犯任何知识产权；和材料，具体主张，教唆或怂恿非法活动。

Specific resistance and its change rate under compressive strength of cement paste admixing with two kinds of nano-TiO_(2) or carbon fiber were studied.

对材料特性以及各种性能之间耦合作用的深入研究，使材料向高性能、多功能和智能化方向发展是材料研究的重要趋势。

However, this usefulness of GaN for optoelectronic devices seens to be limited by the fact that the defficulty in obtaining p-type material is to grow crystals by admixing GaP to GaN. As will known, GaP with n- or p-type conductivity can be easily obtained by suitable doping. Thus, it might be possible to get n- and p-type GaP_(1-x)N_x or GaAa_(1-xN_x crystals above some critical P content of the alloy system.

把两种或两种以上材料组合起来实现优异性能材料的方法是一种经常使用并行之有效的方法，本论文就是对GaP、GaAs与GaN形成合金系GaP_(1-x)N_x和GaAs_(1-x)N_x进行基础性研究的结果，人们预测这种合金系的禁带宽度应在磷化镓的2.261eV(或砷化镓的1.43eV)到氮化镓的3.39eV之间，如果能制成上述合金系则是很有意义的，它是很有希望的蓝色发光材料。

The leak paths are reduced and the tortuosity of leak paths are aggrandized when Al fine powders are added into Al2O3-based seals, which enhance the materials' hermetic property and mid-term stabilities.

Al微粉的加入，减少了材料中的漏气通道，增加了漏气通道的弯曲程度，不仅提升了材料的密封效果，而且改善了材料的中期稳定性。

Wheel/rail noise of the high-speed slab track on concrete bridge and that of the urban elevated supporting block track are predicted respectively. Noise of the slab track, compared with that of the ballasted track, is more severe. The noise of the slab track is about 6.2dBA higher than that of the ballasted track for the receiver nearby the rail, and about 3.5dBA higher than that of ballast track for the receiver

对降低高速铁路桥上板式无碴轨道及城市轨道交通桥上支承块式无碴轨道轮轨噪声的技术措施进行了研究，包括：(1)分别就板式轨道和支承块式轨道结构参数的低噪声设计原则进行了研究；(2)对几种典型的新型轨道用吸声材料的降噪效果进行了分析，结果表明降噪效果显著；(3)就声屏障高度、位置、形状以及声屏障内侧敷设吸声材料对降噪效果的影响进行了分析，结果表明：声屏障越高、越接近轨道，降噪效果越好；声屏障内侧敷设吸声材料，可降低钢轨近旁噪声2.0～3.0dBA，可降低近地面噪声约1.5～2.0dBA

DEEPBLUE inflatable boats use not only P.V.C but also Hypalon coated fabric made from four calendered sheets ensuring perfect watertightness and rubber of the highest xohesive ability.

DEEPBLUE游艇不仅采用P.V.C材料而且也采用Hypalon材料，这种由四层压在一起的表层材料能够确保优良的耐用性。

In the design, we should note two things: It is a wine of surface material and the adhesive strength between the inner layer material is lower than the label adhesive strength; second label wine of the tear strength is higher than the surface material The tear strength, its purpose is to easy to damage when in open box Diaobao Cartoning.

在设计时，我们应注意两点：是一酒盒表层材料与内层材料之间的粘合强度要低于标签的粘合强度；二是标签的抗撕裂强度要高于酒盒表层材料的抗撕裂强度，其目的是为了易于在开盒时破坏掉包装盒。
