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。

An automatic algorithm was used in the analysis to identify clusters of groupings of patients. We used the classical unsupervised clustering method called the Iterative Self-organizing analysis technique of DATA analysis originally introduced by Ball and Hall.25 The technique allows the splitting and merging of clusters while trying to find the "best" configuration. It therefore, requires very little a priori knowledge about the data and predefining the possible number of clusters or groups is not required. The range of possible minimum and maximum number of clusters within which the algorithm can search for an optimal configuration was determined by a procedure called the chainmap which reorders the multidimensional data in the form of a 2D distance map.26 A patient vector is randomly selected and its nearest neighbor is identified as that with the shortest distance between the 2 patients' vectors.

使用自动算法来分析鉴别患者组的聚类，我们使用经典的最初由Ball和Hall提出的的非监控聚类方法，该技术允许在寻找&最佳&形态使对聚类进行拆分和组合，他不需要对数据专门的知识和对聚类或群的可能数量进行预设，在聚类可能的最大和最小范围内，算法可以通过一个叫Chainmap的程序寻找最理想的形态，该程序记录了来自2D距离图的多维数据。

The inner asteroid belt looks identical to ours in terms of material, and it orbits at 3 astronomical units from Epsilon Eridani — the same distance between the sun and the rocky asteroid belt between Mars and Jupiter. An astronomical unit equals the average Earth-sun distance of 93 million miles, or about 150 million km.

But more surprising miracle is,however, not the majestic pyramids of Khufu posture, but the number of "coincidences": people now know,the distance from the Earth to the sunis 146.24 million km, and the average distance between the Sun is 146590000 km, being a unit of astronomical measurement; If the current height of the pyramid of Khufu 146.59 meters get multiplied by the billions, the result is exactly 146,590,000 kilometers!

但更为令人吃惊的奇迹，并不是胡夫金字塔的庞大，而是发生在胡夫金字塔上的数字&巧合&：人们到现在已经知道，从地球到太阳的距离，也就在14624万公里到15136万公里之间，而人们将地球与太阳之间的平均距离14659万公里作为一个天文度量单位；如果把胡夫金字塔的高度146.59米乘以十亿，其结果正好是14659万。

Tagore said:"the world's farthest distance is the distance between life and death, but I stand before you, you do not know that I love you."

Miss you more than one in every second time, I will be melancholy, who slowed the pace of our smoke, I have Gankui perhaps God should give us Kyrie eleison, then Who knows who has long considered the presence of each other in mind, How can the length of the distance and the distance forget themselves.
