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。

My baby more than 9 months, in eight months, she made a fire, and later was also something rash, back there, abdomen also, so we looked to go to the hospital with baby , paediatricians do not see what is the rash, but also so that we have to look at infectious is measles, infectious measles, doctors ruled out, we asked her what, she can not come, what is perhaps the only viral rash .

我宝宝九个多月了，在八个多月时，她发了一次烧，后来身上还出了些疹子，背部也有，腹部也有，于是我们带宝宝去医院看了，儿科医生看不出来是什么疹子，还让我们抱到感染科看是不是麻疹，感染科的医生排除了麻疹，我们问她是什么东西，她也说不上来，只说也许是什么病毒性疹子。

Though he pitched almost three more innings with the torn nail, the righthander is not a definite for his next scheduled start.

虽然他带著那断裂的指甲多投了几乎有三局，但小王这位右投手还不确定是否会依原订计划进行下一次先发。

Many a time and oft were they wont to come there to that favourite nook to have a cosy chat beside the sparkling waves and discuss matters feminine, Cissy Caffrey and Edy Boardman with the baby in the pushcar and Tommy and Jacky Caffrey, two little curlyheaded boys, dressed in sailor suits with caps to match and the name H.M.S.

她们曾多次到自己所喜爱的这个地方来，在闪亮的波浪旁亲切畅快地谈论女人的家常。西茜。卡弗里和伊迪。博德曼将娃娃放在婴儿车里，还带着两个鬈发的小男孩汤米和杰基。卡弗里。他们身穿水手服，头戴水手帽，衣帽上均印染着H。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
