Here we introduced oxadiazole moiety to theside-chain of Ph-PPV to enhance the electron transport properties. The luminescenceefficiency and luminescence brightness (1.33cd/A, 9400 cd/m~2) of the Ph-PPV withside oxadiazole moiety are much higher than non-oxadiazole Ph-PPV (0.70 cd/A,2300 cd/m~2), and these polymers emitted green light which unaffected by theintroduction of oxadiazole moiety. Anthracene has a rigidity and planar structure which shows high photoluminescenceand thermo-stability.

结果表明，以十烷氧基作为间隔基使噁二唑单元键接在苯基取代PPV的侧链，所得材料制备的电致发光器件的效率和亮度(1.33cd／A，9400 cd／m~2)明显高于不含噁二唑单元的苯基取代PPV(0.70 cd／A，2300 cd／m~2)，噁二唑单元的引入并不影响材料的发光光色，膜状态下的荧光发射光谱和电致发光光谱均呈绿光发射。

However,compared to Cd~(2+) stress alone, treatment of SNP+Cd~(2+) caused more increases in SOD,CAT and POD activities, a decrease of H_2O_2 level and MDA content in leaf and root ofmung bean seedlings. These results indicated that exogenous NO induced increases inSOD, CAT and POD activities, which scavenged H_2O_2 and resultantly inhibitedmembrane lipid peroxidation in leaf and root of mung bean seedlings under Cd~(2+) stress.

说明NO通过诱导膜保护酶活性的提高，降低了活性氧水平，从而使Cd~(2+)胁迫诱导的膜脂过氧化程度降低，这可能是外源NO明显缓解Cd~(2+)胁迫抑制绿豆幼苗生长发育的原因之一。

The Isocon analyses also shows that the altered quartz sandstone of the Salitashi deposit which enriches in Cd, As, Ba, Sb, Ag, Co, Ni and Fe, gained Pb, Zn, Cd, Ag, Co, but lost Mn, Zr, Ba, V and Cr during it alteration, the ore and its dolomitized limestones intensively enrich in Ag, Cd, As, V, Cr, Co, Ni and Cu also.

矿石中强烈富集Ag、Cd、As和过渡族元素V、Cr、Co、Ni、Cu，且Cr、Co、Ni在矿石中的富集程度远远高于矿区碎屑岩，近矿白云质灰岩具有和矿石相近的元素富集特征，该矿床的早期矿化和后期的改造成矿作用都与深部岩浆去气有关。

A universal card with multi-purpose refers to a card that can be used in both of card brushing reader and optical driving to fetch data. It is mainly made as to set a CD fetching face and a magnetic strip on the disc (thickenss of 0.8 mm) being produced in accordance with ISO 7816 agreement rules to fetch the data stored in the magnetic strip or IC card by inserting them to a card brushing machine or a card inserting machine. The disc also can be placed on the fetching sheath disc of 0.4 mm thickness and further to place them together into an optical driving firmly for reading out data on CD fetching face by optical fetching head in optical driving so that it is not only integrating magnetic card, IC card and CD disc for easy to carry but also increasing the safety in using, storing volume of the disc and expanding the using range.

本发明涉及一种多用途万用卡，尤指一种可同时适用在刷卡卡片阅读机及光驱内进行数据读取的多用途万用卡，其主要是在一符合ISO 7816协议规范(厚度0.8mm)的盘片上设有一CD读取面及一磁条，可插入一刷卡机或一插卡机内读取磁条或IC芯片内的储存数据，而该盘片又可放置在一厚度为0.4mm的读取套盘上，致使当该盘片放置在读取套盘后可安稳放置在一光驱内，且方便光驱内的光学读取头读取CD读取面内的数据，因此不仅可整合一磁卡、IC卡、CD片等于一盘片中以方便携带，又可提高盘片使用的安全机制、内存容量及扩展其使用范围。
