Vegetation ecotype tend to be xerophyte and even hyper-xerophyte and finally replaced by annual plant. Community structure and species diversity also decrease as the ecological environment worsen, In this process, the height, coverage and biomass decreases by 56.6%、 80.8% and 74.2% respectively compared to steppe, and the indices of species richness, diversity and evenness decrease by 76.4%、 56.7% and 32.0%, but β diversity indices increase by 14.6 times, especially the decease of species gregariousness and the breadth and overlay of species Niche shows that grassland tend to be more sandy and vegetation retrogression succession take place.

其中，植被生态型逐渐由中旱生向旱生、超旱生过渡，并最终被一年生植被替代；群落结构及多样性呈明显递减规律，到严重沙化阶段，草群高度、盖度、生物量与典型草原相比，下降幅度分别达到56.6%、80.8%和74.2%；物种丰富度、多样性及均匀性分别降低76.4%、56.7%和32.0%；而群落β多样性增长14.6倍，特别是多年生物种群聚度降低和生态位宽度、生态位重叠值的下降，表明草地沙化，植被发生逆行演替。

It is different from the Hoskins potential vorticity theory to explain the positive potential vorticity abnormal in upper level and the positive feedback of cyclone in lower layer which the plateau is a strong warm source that the heating effect is stronger than the warm air advection. The superadiabatic state is frequently appears over the plateau, it would be favorable to the development of the cyclonic circulation.

与Hoskins用位涡思想来阐述高层正位涡异常与低层气旋的正反馈作用不同的是，夏季高原本身是巨大的热源，这种加热甚至比暖平流加热还强；高原上经常出现"超干绝热"现象，这将使得高原上的气旋性环流加强幅度比其他情况下更大；由于高原地形的抬高使得从高原到上层扰动的气层厚度小于Rossby穿透高度HR=fL/。。。

Sliding of grains boundary and interface was a main mechanism of superplastic deformation of metal matrix composite. Dislocation did major action to coordinate this two sort of slidings, in the meantime, stacking-faults and twin-crystals did asistant action.

经过对上述问题的研究，本文对金属基复合材料超塑变形的微观过程给出概括性的描述：金属基复合材料超塑变形的主要机制是晶界及界面滑动，位错对实现这两种滑动起主要的协调作用，层错与孪晶则起辅助的协调作用。

The cephalometric radiography and ultrasound image of swallowing were recorded just before and after anterior teeth retraction. All the changes and correlation between the variable of anterior teeth and the variable of tongue movement during swallowing were all discussed. The result showed that there was no significant change on duration and magnitude during swallowing after anterior retraction.

以13位符合条件的志愿者为受测对象，分别在前牙退后之前后各取一次测颅X光片及超音波吞咽之影像资料；而后以测颅X光片描绘取得前牙距离、角度的改变比率，另以电脑辅助分析超音波吞咽影像，得到舌头吞咽各分期的时间振幅之改变比率，再进行统计分析。

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。
