The Cardo structure could increase the solubility and thermal stability of the resultant polyimide.

通过在聚酰亚胺的主链中引入庞大侧基（9，9-二苯基芴）形成轴状聚酰亚胺，同时提高聚酰亚胺的溶解性和热稳定性；庞大的侧基又能阻止链的堆砌，避免生色团荧光链间淬灭；通过加入第二种二酐单体合成三元缩聚型聚酰亚胺，调控荧光性二酐在聚酰亚胺中的含量，降低生色团在聚酰亚胺中的浓度，来避免生色团荧光浓度淬灭，增加聚酰亚胺的固态荧光量子效率；通过使用热稳定性好的稠环生色团苝和吖啶来避免共轭类生色团（如含双键或三键的生色团）在高温下热交联及氧和水的破坏。

Results show that obduction and napper were main tectonic movements in late Indosinian-early Yanshan period of Lower Yangtze Region, and most areas were elevated and denudated. Source rocks of lower-Paleozoic in some areas did not deep bury renewedly, and remain the Indosinian thermal evolution state. Therefore the high maturity sapropelic organic matter of lower-Paleozoic has still possessed hydrocarbon generation potential.

研究结果表明，晚印支-早燕山期，下扬子区的构造运动以逆冲推覆为主，大部分地区遭到抬升剥蚀，部分地区下古生界烃源岩抬升后晚期没有再度深埋，保留了印支期的热演化状况，因此下古生界高成熟腐泥型烃源岩现今仍具有一定的生烃潜力。

In the present paper, the induction characteristic of lymphoblastoid, in-terferon in vitro is described. Results indicate that Namalwa cell line possesses a higher interferon-inducing ability than Raji and Yu-Nu cell lines. NDV B1 strain, F strain and Sendai virus can induce more interferon than BB1 virus and poly 1 : C. Priming of pretreating cells with homologous interferon or superinduction did not effect interferon production. The optimal cell concentration for interferon induction is about 106 cells/ml...

本文研究了类淋巴母细胞干扰素的诱导特性：Namalwa细胞系的干扰素诱生能力大于Raji和余奴系，而诱生剂中以NDV和仙台病毒诱生干扰素的能力较大，但"起动"和超诱导均无作用；诱生干扰素适宜的细胞浓度为10~6/毫升；增殖期的Namalwa细胞诱生能力较大；黄芪和5'-溴脱氧尿嘧啶核苷对Namalwa细胞干扰素的诱生系统有明显刺激作用，在最适条件下粗制干扰素平均滴度可达40，000单位/毫升。

Express as a result that the study area gets close to hydrocarbon generation center, have high-quality coal measures hydrocarbon source rock along with big hydrocarbon generation intensity, so it has abundant gas source and the material foundation to form large scale natural gas reservoir; Evaporitic tidal flat facies of the Ordovician Majiagou Formation in this area is situated in the austral expanded range of the karstification zone, and is the optimum natural gas prospecting targets of the lower-Paleozoic; In the south of study area, there are well-developed delta deposition system sand bodies of Shanxi Formation and Xiashijezi Formation, hence this area becoming the most beneficial Neopaleozoic natural gas enriched region; In this area, the Paleozoic develop various concealed non-structured traps, the natural gas migration and accumulation process is very beneficial and both the cover and the conservancy condition are also very good.
