煤的形成过程

煤,早在800年前就被广泛用作工业生产的燃料,推动了当时工业的向前发展,随之发展起煤炭、钢铁、化工、采矿、冶金等工业。煤在地球上的储量丰富,除了作为燃料以取得热量和动能以外,更为重要的是从中制取冶金用的焦炭和制取人造石油,即煤的低温干馏的液体产品——煤焦油。经过化学加工,从煤炭中能制造出成千上万种化学产品,所以它又是一种非常重要的化工原料,我国相当多的中、小氮肥厂都以煤炭作原料生产化肥。煤也被人们誉为“黑色的金子”。

潍坊市局创新构建三项预警防范体系

2009年以来,潍坊市国土资源局以构建预警防范体系为工作重点,全力推进国土资源系统党风廉政建设取得明显成效,实现“三无”,即：无因软环境问题而被投诉者、无越级信访、无违法违纪问题。被授予全国精神文明建设工作先进单位、全国国土资源系统依法行政工作先进单位。继续保持国土资源部纪检监察工作联系点,被部纪检组、监察局确定为加强基层党风廉政建设工作联系点。创新建立了“三项防范机制”。一是建立廉政告知防范机制。组织全系统科级以上领导干部率先公开作出不违反规定插手建设领域工程,不违反规定住房、用车、旅游、婚丧嫁娶,不接受现金、有价证券和支付凭证等12条廉政承诺。积极开展廉政谈话,结合全系统干部调整,对新任职党员领导干部进行集体任前廉政谈话,适时进行防范教育。同时,坚持把关键单位、岗位和人员作为提醒防范的另一重点,强化防范教育。二是建立监督纠错防范机制。适时对县市区局纪委书记（纪检组长）进行了调整,市局和所属17个县市区局全部成立了纪委（纪检组）,配齐了纪委书记或纪检组长,设立了纪检监察室,国土资源所全部配备了专兼职纪检监察员,形成了市县乡三级国土资源纪检监察工作网络。加强纪检监察干部队伍的培训与交流,学习纪检业务,不断提高纪检监察干部队伍的能力素质。

运用nrDNA ITS 数据研究角叉菜属(Chondrus)在红藻门中的系统进化地位

测定了角叉菜属(Chondrus)5个代表种的核糖体DNA内转录间隔区(ITS)及5.8SrDNA基因序列。结果表明,角叉菜属ITS区(含ITS1、5.8SrDNA和ITS2)序列长度范围为704—714bp,G+C含量为44.6%—45.7%,变异位点69个,信息位点16个;其中,ITS1和ITS2的长度范围分别为147—149bp和398—404bp。5.8SrDNA长度为158bp,没有变异和信息位点。由MEGA3构建的系统进化树(ME和MP)显示:在进化尺度上,真红藻纲的松节藻科(Rhodomelaceae)与红毛菜纲(Bangiophyceae)亲缘关系较近。在真红藻纲内,杉藻目(Gigartinales)的进化地位相对较高,其次是海膜科(Halymeniaceae)、石花菜科(Gelidiaceae)、红叶藻科(Delesseriaceae)和粉枝藻科(Liagoraceae)等,而松节藻科进化地位相对较低。在杉藻目内,杉藻科(Gigartinaceae)和胶黏藻科(Dumontiaceae)进化关系密切,而形态学特征相似的角叉菜和马泽藻(Mazzaella)亲缘关系非常近。     

Denitrification in Qi'ao Island coastal zone, the Zhujiang Estuary in China

Samples of sediments and the overlying water were collected in the Qi'ao Island coastal zone, the Zhujiang (Pearl River) Estuary (ZE). Denitrification rates, sediment oxygen demand (SOD) , and fluxes of inorganic nitrogen compounds were investigated with N2 flux method, using a self-designed continuous flow through and auto-sampling system. The results indicate that the denitrification rates varied between 222 and 908 μmol/(m2·h) with an average of 499 μmol/(m2·h). During incubation, the sediments absorbed dissolved oxygen in the overlying water with SOD ranging from 300 to 2 363 μmol/(m2·h). The denitrification rates were highly correlated with the SOD (r2 =0.77) regardless of the NO3- + NO2- concentrations in the overlying water, organ- ic carbon contents in sediments and water temperature, suggesting that the SOD was probably the main environ-mental factor controlling the denitrification in the Qi'ao Island coastal zone. There was a net flux of NO3- + NO2-into the sediments from the overlying water. The NH4+ flux from sediments into water as the result of mineraliza-tion was between 12. 3 and 210. 3 μmol/(m2·h) ,which seems limited by both organic carbon content in sedi-ment and dissolved oxygen concentration in the overlying water.     

Analyses of the long-term salinity variability in the Bohai Sea and the northern Huanghai(Yellow) Sea

Based on the comprehensive collection of the field observed salinity of the Bohai Sea (BHS) and the northern Huanghai Sea (NHS) from the 1950s to the present,the patterns of 10-years-averaged salinity at the different layers in the recent five decades (the 1950s,the 1960s,the 1970s,the 1980s and the 1990s) are obtained by the spatial-temporal interpolation technique with the scrupulous data quality control in this study.Then,by combining the spatial-temporal interpolation technique with successive correction method,the annual distributions of salinity both in the BHS and in the NHS are obtained as well.The data analyses indicate that the overall salinity in the BHS and the NHS increases from the 1960s till the present,with the increase of annual mean salinity of 0.04 psu from the 1950s,and the maximum increase rate of salinity is about 0.14 psu/a in the Bohai Bay.The high salinity tongue extended significantly from the NHS into the BHS.The intensified eastern wind field is related to the western intrusion of the NHS warm current,which probably leads to the moving forward of the high salinity water mass into the BHS.However,it is rather different from the salinity distribution characteristics between the 1950s and the 1960s.The extensive precipitation in the 1960s could lead to an increase in the discharge of the Huanghe River,which might result in the decrease of salinity in the BHS.But the salinity isoline of 32 in the NHS still extended significantly into the BHS in the 1960s.Since the 1980s,the patterns of salinity distribution have changed thoroughly.The salinity in the central area of the BHS was low,while the salinity in the Bohai Bay and the Liaodong Bay was higher than the other regions with its horizontal salinity gradient decreasing in the 1980s.The Empirical Orthogonal Function Analysis (EOF) is also conducted to study the interannual salinity variability of the BHS and the NHS.The correlation coefficient between the time coefficient series of the main mode and the Huanghe River discharge can reach -64.57%.It can be concluded that salinity variation of the BHS and the NHS has strong negative correlation with the Huanghe River discharge.
