Five typical coals of low-to-medium rank (Huolinhe brown coal, Majiata non-caking coal, Datong weakly caking coal, Huozhou gas coal, Lingshi fat coal) and their macerals are prepared. The molecular structure and the oxygen functional groups of the selected coals and their macerals are studied by means of the conventional coal properties analysis, chemical analysis and the advanced instrumental methods such as FTIR,XRIK 13C-NMR.N XPS. The molecular structure characteristics, regularities and the results are discussed. Additionally, the total oxygen content and distribution characteristics of different oxygen functional groups in the raw coals and their macerals are studied.

Such features are typical of ancient lower continental crust, e.g., Archean granulite terranes that experienced extensive U-Th loss and developed time-integrated low radiogenic Pb compositions. The occurrence of the west Ujimqin andesites indicates the existence of ancient continental lower crust beneath the NE China fold belt.4 The Mesozoic granitoids in the Zhangguangcai Range and Jiamusi block have lower Nd ε_(Nd =-3.5～+ 2.1, T_ = 1.0～1.27Ga and highly radiogenic Pb and Sr isotopic composition ~(206Pb/~(204)Pb = 18.4～18.9,~(87)Sr/~(86)Sr = 0.705～0.711, suggesting that the pelagic sediments of the Paleo-Asian Ocean or their metamorphosed derivates were an important component in the region.5 The Pb isotope mapping results show that the mafic rocks in the northern Hinggan Mountains have higher and weakly variable ~(206)Pb/~(204)Pb ratios than those from the southern Hinggan Mountains and the Liaoyuan-Yanji area.

该套岩石的出现为证明东北地区存在古老大陆下地壳提供了重要证据。4张广才岭-佳木斯地区中生代花岗岩表现出低ε_(-3.5～+2.1)、高T_(1.0～1.27Ga)和高放射成因Sr~(87Sr/~(86)Sr=0.705～0.711和Pb同位素组成~(206Pb/~(204)Pb=18.4～18.9，反映了古亚洲洋远洋沉积物或变沉积岩为区域地壳的重要组分之一。5同位素填图结果表明，大兴安岭北区基性火山岩表现出较高且变化小的~(206)Pb/~(204)Pb比值；而南兴安岭-辽源-延吉地区中生代基性火山岩整体上表现出相对北区低~(206)Pb/~(204)Pb同位素比值特征。

The different adsorbed species such as sulfates sulfites and adsorbed sulfur dioxides under various temperature, pressure and evacuated treatment conditions were characterized by in situ-IR. In the absent of oxygen, two bands were observed at 1050cm〓 and 1330cm〓, the former is the weakly chemisorbed sulfur dioxide species and the latter is the strongly chemisorbed SO〓.

首次利用正电子淹没技术求取了CeO〓在MgAl〓O〓上单层分布的阈值为0.075g／gMgAl〓O〓，此值略小于利用XRD法求取的单层分布阈值0.08g／gMgAl〓O〓，并且发现催化剂的氧化吸硫活性，O-Ps的生成率与CeO〓的负载量之间良好的对应关系，当CeO〓在MgAl〓O〓上形成单层分布时，O-Ps的生成率最小，此时，催化剂的活性最优。

The exchange and adsorption properties of LA, FA and glu on six anion exchange resins were investigated, and the influence of the temperature was also researched, among them weakly basic ion-exchange resin 335 can provide the highest uptake capacity of LA The Freundlich equation can explain the adsorption equilibrium curves of LA on the anion resins better than the Langmuir equation.

The results indicated that four SOD bands were identified in five tissues, and the band with the biggest mobility ratio were found weakly in gill, digestive gland and adductor muscle but not in foot and mantle. Two ATPase bands were found in four tissues except digestive gland. One MDH band was found in five tissues, but the MDH gene expressed strongly in foot and adductor muscle. Two ME bands were examined in foot, adductor muscle and mantle, but the band with smaller mobility ratio was found in gill and digestive gland.

结果表明，SOD在紫贻贝的5种组织中均有表达，共有4条酶带，但迁移率最大的酶带在足和外套膜中未出现，而在另外3种组织中呈弱表达；ATPase在除消化腺外的组织中都表现为2条带；MDH在5种组织中都表达出1条酶带，其中足和闭壳肌的MDH染色最深；ME存在1~2条酶带，其中迁移率大的条带在5种组织中都有表达，而迁移率小的条带只存在于外套膜、闭壳肌和足中。
