盐湖

These surprisingly beautiful and colorful pictures come to us from Etosha National Park, Namibia.

这些惊人的美丽，丰富多彩的图片来我们从盐湖国家公园，纳米比亚。

Before the end of our tour, we got a chance to visit the Salt Lake Museum in which the all-shaped salt crystals were exhibited.

最后我们来到了盐湖博物馆，我看到了形态各异的盐花，从向导的介绍中我了解到由于这里地处戈壁，气候炎热干燥，加上长时间风吹日晒，湖水浓度升高结晶成盐粒，并幻化成令人赏心悦目的盐花，成为难得一见的奇观。

ABSTRACT Chemical corrosion mechanism of concrete in Qinghai salt lake is briefly reviewed, and bittern resisting behavior of high alumina cement concrete, magnesium oxychloride cement concrete, alkali-activated slag concrete, ferrialuminate cement concrete and polymer impregnated concrete are also reported in the paper.

摘 要 简述了普通水泥混凝土在盐湖环境中的受腐蚀机理﹔报道了高铝水泥、氯氧镁水泥、铁铝酸盐水泥、碱矿渣和聚合物浸渍混凝土的抗盐卤腐蚀行为﹔对硅灰高密实混凝土的抗盐卤腐蚀机理进行了详细讨论，认为改善孔结构是获取混凝土高抗腐蚀性的有效途径。

大美青海邮资明信片典藏台历》所精选的12幅摄影作品，包括了青海湖鸟岛、塔尔寺、青藏铁路、西宁中心广场、龟山平湖、年保玉则、金色草原、盐湖之光等多处人文和自然景观。

The layer of solid KCl is so thin in depth、so small in size、 and so low in grade that it is too difficult to exploite it. Besides that, only 1/3 of the liquid KCl can be expoi ted due to the mining method of well and canal drainage which is being used now. Therefore, it is one of the key problems to exploite the liquid KCl as possible as we can and to turn the solid KCl into explo itable liquid deposit in Qarhan salt lake. So the idea of dissolving and driving exploitation has been suggested. This paper will deal with three problems as follow

然而由于固相矿层薄、品位低而难以直接开采利用，加之目前对液相矿产只是纯疏干性开采，充其量只能采出1/3的液相矿，因此如何最大限度地开采液相矿产，同时将固相矿产转化成能直接开采利用的液相矿产是察尔汗盐湖开采中急需解决的关键问题之一，对此人们提出溶矿驱动开采的设想，本文正是以此为目的，着重研究以下三个问题

Coming up on its eighth year, the Great Salt Lake Bird Watching Festival is good get away for birders.

In chapter 7, chloride absorption or binding isotherm of concretes was investigated, linear chloride binding capacity and a non-linear coefficient were firstly proposed, based on a large amount of experimental data of concretes under the actions of single, double, or multiple factors in four typical bitterns.

第七章根据不同混凝土在4种典型盐湖的单一、双重和多重因素作用下的大量数据，研究了混凝土对氯离子的吸附/结合规律，提出了线性氯离子结合能力和非线性系数的新概念。

Results show that when exposed to the severe environment of salt lakes, both OPC and APC display poor durability, though HSC shows excellent bittern-freezing-thawing durability, the corrosion resistance against bitterns is not so good, while non-air-entraining HPC shows outstanding performance in both bittern-freezing-thawing durability and corrosion resistance against bitterns, and the performance can be farther improved by adding fibers.

结果表明，在盐湖地区的严酷条件下，OPC和APC的耐久性不好，HSC具有优良的抗卤水冻蚀性，但是其抗卤水腐蚀性比较差，高强非引气HPC具有优异的抗卤水冻蚀性和抗卤水腐蚀性，纤维增强HPC的效果更佳。

Then the experiments on the separation of lithium and magnesium from bitterns contenting lithium were carried out, during the experiment NaOH was chosen as addition to further remove magnesium from the extraction liquid and Na_2CO_3 was chosen as deposition agent to prepare Li_2CO_3 product.

作者选取磷酸三丁酯为萃取剂，200#溶剂汽油为稀释剂，氯化铁(FeCl_3)为共萃取剂，对盐湖含锂卤水进行萃取分离镁锂的试验，然后采用氢氧化钠对萃取液进行深度除镁，再用碳酸钠作为沉淀剂制备碳酸锂产品。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
