红外光谱技术具有快速、经济、高效等特点,是现阶段国内外地质找矿工作中被广泛应用的一项高新技术。通过研究矿物在红外波段上的差异性吸收特征,开展红外光谱填图和波谱参数分析工作,进而确定矿化区域内的特征矿物组合以及指向矿化热液中心的矿物波谱参数变化范围。近年来,随着光谱分辨率的提高和解混算法的优化,越来越多的波段被应用于岩矿信息提取工作,其中发展成熟的短波红外技术(SWIR, 1 100~2 500 nm.,对于绢云母、高岭石、明矾石和绿泥石等中低温黏土矿物有较好的识别效果,通过这些矿物的波谱参数变化规律成功在斑岩型、浅成低温热液型、 Vm.型等矿床中建立了找矿勘查模型;热红外技术(TIR, 6~15μm.主要针对长石、石英、石榴子石和辉石等中高温矿物有更好的探测能力,近几年在矽卡岩型矿床中有着出色的表现;中红外技术(m.R, 3~6μn)在地学领域找矿勘查工作中还处于研究阶段,没有形成一套完整的矿物信息提取方法。对红外光谱技术在地学领域的发展历程进行了综述,对各个波段引起波形变化的原因、常用的波谱参数及其表征的含义、四类测试仪器进行了总结,描述了常作为找矿指标的四种矿物——绢云母、绿泥石、石榴子石和碳酸盐类矿物的波谱特征。说明了红外光谱技术在矿产勘查工作中两大核心内容以及目前可能存在的问题。最后对未来红外光谱技术在地质找矿工作中的应用提出了几点建议,即加强规律验证工作,建立多波段、多平台综合光谱勘查模型和建立矿区的波谱库与参数提取标准。

Angiotensin II (Ang II) is the m.in m.diator of the Renin-Angiotensin-System.acting on AT1 and other AT receptors. It is regarded as a pleiotropic agent that induces m.ny actions, including functioning as a growth factor, and as a contractile horm.ne, am.ng others. The aim.of this work was to exam.ne the im.act of Ang II on the expression and function of α1-adrenergic receptors (α1-ARs) in cultured rat aorta, and aorta-derived sm.oth m.scle cells. Isolated Wistar rat aorta was incubated for 24 h in Dm.m.at 37˚C, then subjected to isom.tric tension and to the action of added norepinephrine, in concentration-response curves. Ang II was added (1 × 10−5 m., and in som. experim.nts, 5-m.thylurapidil (α1A-AR antagonist), AH11110A (α1B-AR antagonist), or Bm.-7378 (α1D-AR antagonist), were used to identify the α1-AR involved in the response. Desensitization of the contractile response to norepinephrine was observed due to incubation tim., and by the Ang II action. α1D-AR was protected from.desensitization by Bm.-7378;while RS-100329 and prazosin partially m.tigated desensitization. In another set of experim.nts, isolated aorta-derived sm.oth m.scle cells were exposed to Ang II and α1-ARs proteins were evaluated. α1D-AR increased at 30 and 60 m.n post Ang II exposure, the α1A-AR dim.nished from.1 to 4 h, while α1B-AR rem.ined unchanged over 24 h of Ang II exposure. Ang II induced an increase of α1D-AR at short tim.s, and Bm.-7378 protected α1D-AR from.desensitization.

m.crofaunal com.unities of threatened subtidal m.ёrl seabeds on Tenerife (Canary Islands, north-east Atlantic Ocean) in sum.er

Acta Oceanologica Sinica 2012年第1期31卷 98-105页

This study contributes with the first data on physical and taxonom.cal structure of m.crofaunal assem.lages of m.erl beds from.the Canary Islands. m.erl beds and Cym.docea nodosa m.adows of the Canary Islands are considered biodiversity hot-spots in term. of taxonom.c and functional biodiversity with a broad geographical and depth ranges. The authors have studied the structure of the m.crofaunal assem.lages on different habitat types （Cym.docea, Caulerpa, sabellid field, garden eel and m.erl beds）. Sam.les were taken at a range of depths between 14 and 46 m. Correlations were perform.d am.ng abiotic variables （granulom.try, organic m.tter, nitrogen and phosphates） and the m.st abundant taxa. Sim.larity analysis was perform.d to explore the patchiness of seabeds at a local scale. Significant differences were found in m.crofaunal assem.lages am.ng seabed types, with highest abundances and lowest biodiversity in sabellid fields, where the sabellid Bispira viola dom.nated. The polychaetes Aponuphis bilineata and Chone filicauda and the m.llusc Turritella brochii were the m.st abundant taxa on m.erl beds. The m.saic of granulom.tric conditions would explain the associated m.croinfaunal com.unity structure and contribute to the creation of diversity on these relatively well preserved seabeds at a local scale.
