查询词典 carbonate rocks

As the sample of Yuanliangshan tunnel in Chongqing-Huaihua Railway, based on the full analysis of groundwater specimens, five chemical equations are designed to calculate evaluating data by the relation of activity, equilibrium constant and Gibbs free energy. According to the two criterion of partial pressure of carbon dioxide and reaction direction, the result calculated shows the groundwater has weak corrasion to carbonate rocks, which should be avoided to do harm to tunnel.

以渝怀线圆梁山隧道为实例，通过隧道内地下水取样进行了全分析，其中CO(上标 2-下标 3)离子作为"中间过渡态"离子，由于只存在微小量未被检出；使用水质分析结果数据设计了五个化学反应方程式，通过活度、反应平衡常数及吉布斯自由能之间关系进行热力学计算，依据二氧化碳气体分压P(下标 CO2)与反应进行两个方向化学反应判据开展分析，结果表明地下水具有弱侵蚀性，在隧道工程中应避免其引起危害。

Trees play an important role in the sequestration of atmospheric CO2 in magnesium and calcium carbonate rocks.

在二氧化碳结合成镁、钙碳酸盐的过程中，树木扮演着一个重要的角色：当山体增长，岩石会分裂开来，然后被运送到丘陵上，接着树木会使埋藏在泥土中的岩石分解成其他矿物，然后这些矿物就会跟空气中的二氧化碳结合。

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。

The achievement of this project can be briefly summed up as following:(1)the carbon contributing to karst processes mainly comes from ecological system itself under the condition of existence of vegetation and soil covers;(2)results indicates that the depositing processes of rainfall to CO2 is an important "sink" to global carbon cycle;(3)owing to the differences of vegetation and surface covering, the adjusting effect of ecosystem to environmental humidity, temperature and CO2 concentration near surface air which indicates different benefit of preventing water and soil from lose is marked;(4)the preponderant species of vegetation in the karst ecosystems which have different kinds of carbonate rocks are obviously variant, and this situation results to the clearly differences of the micro － habitat , structure of surface cover and water holding capacity;(5) the relevant study showed that the carpophagous animals and birds make a important role in the spreading of vegetation seeds. The designed experience for the study of seed reservoir was not able to obtain a satisfactory result.

主要研究成果包括：通过对表层系统碳库的研究，认为在有土壤和植被覆盖时，岩溶作用过程中的碳主要来自生态系统本身而不是母岩；降雨对大气碳具有重要&沉淀&作用，是碳的一个重要汇；不同植被类型表层岩溶系统对系统水份、空气湿度、气温、土温和近地表 CO2浓度等具有明显调节作用，具有不同的水土保持效益；不同母岩的岩溶生态系统的植被优势种、属差异明显，由此形成的小生境、地被物及其持水性差异巨大；对典型岩溶表层系统种子库的试验研究没有取得满意结果，但食果动物、鸟类对种子传播起到一定作用。
