At large scale, the result of comparing of optimization structure of forest type with the present structure of forest type illustrates that the present economical forest area is larger while the mixed forest is smaller. So decreasing economical forest area and increasing mixed forest area should be the main measurements to optimize spatial patterns. At small scale, the evaluation of the landscape inner structure index illustrates that the forest structure and coverage is smaller, which should be regulated and so the uneven-aged, multi-layered and mixed forest should be the object of the forest structure design.

大尺度上根据植被类型优化结构和现有植被类型结构数据的对比分析可知，现有经济林面积则过大，混交林面积较小，因此主要是减少经济林面积，改造针叶和阔叶纯林为混交林，从而增加混交林面积，以达到最优植被类型结构时的空间配置；在小尺度上通过对景观内部结构指数的计算分析可知，该区林分结构和郁闭度分指数值较小，应予以着力调整；由研究结果可知，异龄、多层次、混交的水源保护功能最好，因此稳定的林分结构设计目标就是尽量使林分形成异龄、多层次、混交林。

Based on the language materials collected, the third chapter analyses the understanding restriction conditions of "VP+NP_1+DE+NP_2" ambiguity structure from the NP_2"s life and the VP"s mobility. The author comes to the following conclusions: the NP_2"s life rank with the "VP+NP_1+DE+NP_2" structural ambiguity in understanding becomes the correlation dependence, the monosyllable verb which expresses the hands" and the foot"s movement, easily combining with the tense auxiliary, enter the "VP+NP_1+DE+NP_2" structure to form the latent ambiguity structure; the double syllable verb which has the causes feature is easy to enter the"VP+NP_1+DE+NP_2" structure to form latent ambiguity structure; the double syllable "noun-verb", with the influence of the behind noun NP_1, both can be understood as the valency combination, and the non-valency combination, thus causes the "VP+NP_1+DE+NP_2structure to appear ambiguity.

在第三章中，我们将在语料分析的基础上分别从NP_2的生命度和VP的动性这两方面探讨这一歧义结构在理解上的制约条件：NP_2的生命度等级与&VP+NP_1+的+NP_2&歧义结构理解为偏正结构的几率成正相关关系：表示手、脚等的单音节动词容易与时态助词结合，进入&VP+NP_1+的+NP_2&结构形成潜在的歧义结构；带有致使特征的双音节动词容易进入&VP+NP_1+的+NP_2&结构形成潜在的歧义结构；双音节的&名动词&由于受其后所跟的名词NP_1的影响，既能理解为配价组合，又能理解为非价组合，从而使得&VP+NP_1+的+NP_2&结构出现歧义。

In the aspect of structure line detection, the main idea is to separate the roof structure lines into two parts, one is for external contours and the other is for internal structure lines. The external contours were extracted using Hough transform and other geometric conditions. The internal structure lines were extracted by any two adjacent roof faces intersecting each other. Finally, the two kinds of structure lines were combined to construct the roof shapes.

而在结构线的侦测方面，主要将屋顶结构线分为两个部份来进行，第ㄧ为外部轮廓线，萃取的方式是利用霍夫转换及其他附加几何条件来进行；第二为内部结构线，萃取的方式为利用相邻屋顶面的交会来获得；最后再将此二种特徵线合并在一起，进而重建完整的屋顶面形状。

At present, many tall buildings have been built in China because of the constant development of economy, a lot of large-scale civil buildings such as marketplace, office building, industrial building need long-span and heavy load structure. So the traditional prefabricate structure has been already unable to satisfy the constant increasing need because of the shortcomings of short-span and low intensity concrete. If we don"t change the performance of the former prefabricate structure, it will be very swift that the prefabricate structure will be eliminated. Besides, the commodity concrete"s high development, the technology of concrete pump sending popularization and the development of nobonded presterss technology accelerate the shrink of prefabricate structure.

当前，我国由于随着经济的不断发展，高层建筑大量兴起，很多大型民用建筑如商场、写字楼、工业厂房等楼面都需要大跨、重载的楼板结构，因此传统的预制板由于适合跨度小、混凝土强度低等一些缺点，已无法满足不断发展的需要，如不改进原有预制构件的材料性能，将很快被淘汰，而且由于商品混凝土的飞速发展、混凝土泵送技术的推广及无粘结预应力技术的发展更加速了预制构件的萎缩。

Therefore, the EL spectra of (Znq_2)_4 is wider than that of Znq_2. 4._2 was synthesized. The analysis of molecular spatial structure and the characterization of material performance of_2 and Liq showed that two Liq molecules and two Naq molecules were connected by Na-O-Na bond bridges to form_2. Compared with Liq,_2 exhibits stronger rigidity in planar molecular structure, larger steric hindrance and intermolecular distance, and much smaller molecular polarity, thus resulting in much longer fluorescence lifetime, much higher fluorescence quantum efficiency, wider energy bandgap and better film formability. When used as light-emitting layer in OLED,_2 shows lower formation probability of excited dimmer and exciplex formation than Liq, thus emits bluer light with higher current efficiency than Liq. When_2 ultrathin film is used as electron injection layer in OLED, it exhibits higher current density, higher luminance, lower turn-on voltage and higher current efficiency than Liq ultrathin film for the existence of sodium ions in_2 ultrathin film. 5. The summarization the relationship between molecular spatial structure and material performance of Alq_3,(Znq_2) and Liq, lead the conclusion that the molecular spatial structure of Mq_n affects its material performance in such aspects as the rigidity of planar molecular structure, intermolecular interaction, molecule stacking mode and intermolecular distance.

制备了_2，通过对_2和Liq的分子空间结构与性能进行分析与讨论，发现_2是通过两个Na-O-Na键桥将两个Liq和两个Naq连接构成的，其分子平面结构的刚性程度强于Liq，空间位阻大于Liq，分子之间的距离大于Liq，分子极性远远小于Liq；_2的荧光寿命长于Liq，荧光量子效率高于Liq，成膜性优于Liq；_2的禁带宽度比Liq大，光致发光光谱中_2的最大发射峰较Liq发生蓝移；当_2在OLED中作为发光层时，激发二聚体与激基复合物的生成几率远远小于Liq，发的光比Liq更蓝，电流效率大于Liq；_2超薄膜中有Na离子的存在，与Liq超薄膜相比，当其在OLED中作为电子注入层时，具有更大的电流密度，更高的发光强度，更低的阈值电压和更高的电流效率 5、对上述Alq_3、Znq_2和Liq的分子空间结构与材料性能之间的关系进行了归纳总结，认为Mq_n的分子空间结构主要在分子平面结构的刚性程度，相邻分子之间的相互作用，分子堆叠的方式和分子之间的距离这四个方面影响其性能。
