碳酸盐

Under certain experimental conditions,the Terbiumbasic Calbonate can be dissolved in aqueous solution of nicotinic acid to yield an Orange Tb Complex, which has a broad characteristic absorption band between, 370—410 nm The autoreduction of the Tb—Complex was studied by means of spectrophotometric method, It was determined by experiments that the reaction order is equal to two and the apparent activation energy of the auto—reduction is equal to 68.4±0,8KJ/mol.

在一定条件下，Tb的碱式碳酸盐可以溶解在烟酸的水溶液中形成橙黄色的络合物，该络合物在390nm波长附近有一宽带特征吸收峰。消光值在0。～1.0范围內与Tb的浓度具有直线关系。分光光度法对Tb自还原反应研究确定：于15℃及烟酸浓度为0.35M时，当pH值小于6.0条件下，随pH值的增加，其自还原速度常数减小，该自还原反应级数为二，反应活化能为68.4±0.8KJ/mo1。

Common fillers are various silicates, carbonates and sulfates such as clay, limestone, calcium carbonate, magnesium carbonate, barytes, etc. Water is added to produce a filler that spreads easily when applied and drys into a hard mass.

普通填料有各种硅酸盐，碳酸盐和硫酸盐，如粘土，石灰石，碳酸钙，碳酸镁，重晶石等水是增加生产填料容易传播和应用时drys变成硬肿块。

By means of core observation and log analysis of reservoir, it is recognized that widely distributed Tazhong uplift is formed from the late of Middle Ordovician to the early of Late Ordovician (from Llandeilo in Early Caradoc). The buried hill paleo-karst reservoir developed in the carbonate rocks of the mid-upper section of Yingshan formation of Lower Ordovician and covered by Lianglitag formation of Upper Ordovician is dominated by lithology of granular limestone, micritic limestone and algal elastic limestone interlayered with dolomite of open to semi-restricted platform fades.

通过岩心观察、测井储集层分析等手段，识别出塔中凸起区广泛分布形成于中奥陶世晚期－晚奥陶世早期（兰代洛世－卡拉道克世早期）、发育于下奥陶统鹰山组中上部碳酸盐岩中且被上奥陶统良里塔格组覆盖的古潜山岩溶储集层，其原岩主要为开阔－半局限台地相颗粒灰岩、泥晶灰岩、藻灰岩夹白云岩。

Low magnetic susceptibility, low CaCO3, low organic carbon concentration, low C/A (Chenopodiaceae/Artemisia) ratio, low Sr concentration and, hence, high Rb/Sr ratio in the lake sediments indicate a cold but moist climate during the global Little Ice Age in the Daihai area.

在明确湖泊沉积物Rb/Sr比值古气候指示意义的基础上，通过AMS-14C和210Pb精确定年及12.08米岱海沉积岩心的Rb/Sr比值、碳酸盐含量和有机碳含量的变化，恢复了包括中世纪暖期、小冰期及全新世适宜期等典型气候事件在内的全新世环境演化过程，基本认识是：全新世早—中期9-3.5kaB.P。

The main cobaltiferous mineral states are: cobaltiferous ferruginous sulphide, oxide, carbonate, sulphate, clay mineral and silicate.

大横路钴矿床矿石中的钴为多相多态存在，主要的含钴矿物相有含铁的硫化物、氧化物、碳酸盐、硫酸盐、粘土矿物和硅酸盐，其中粘土矿物吸附态的钴约占矿石总钴量的三分之一，这一赋存状态的钴，用通常的选矿方法难以选取，是造成该钴矿床以往钴回收率低的主要原因之一。
