碳酸钙

In general as long as the temperature reaches 90 ℃, the common E. coli, hepatitis B virus and other bacteria have already perished, but we still continue to boil water, this area is to allow water in the calcium carbonate, magnesium carbonate and other ingredients to fully precipitate impurities, and the other On the one hand, because I am using tap water is treated with chlorine, so a certain degree of residual chlorine in water, in the process of boiling water, chlorine and impurities in the water will generate harmful substances called chloroform.

在一般的长期的温度达90℃，普通大肠杆菌，乙型肝炎病毒和其他细菌已经死亡，但我们仍烧开水，这方面是允许的碳酸钙，碳酸镁和其他水成分，杂质充分沉淀，以及对其他一方面，因为我使用的自来水是用氯处理，因此在水中的余氯，在一定程度上开水，氯和水中杂质的过程中，将生成所谓有害物质氯仿。

CFS is developed by using Polysulfonamide, cellulose, sepiolite andbrucite fibers as reinforced fibers, using acrylonitrile-butadiene and natural rubberas binders, using calcium carbonate, hydrated magnesium silicate, bolus alba asfiller and agent. This new material's main performances reach or are close to thesimilar products of foreign countries, and fill in the domestic gapes in the field.

首次选用有机芳砜纶纤维、纤维素纤维和无机海泡石纤维、水镁石纤维等为代石棉纤维，以丁腈橡胶和天然橡胶为弹性粘结剂，并加入碳酸钙、滑石粉、高岭土等无机填料和其它配合剂，采用压缩成张工艺成功地研制出具有工业应用价值的CFS，其主要性能指标达到或接近国外同类产品的水平，填补了国内在这一领域的空白。

The purpose of this study was to investigate the calcium bioavailability of calcium carbonate and calcium lactate, two common forms of calcium supplementation.

本研究的主要目的在於探讨不同钙片对钙的生物利用之差异，选择市售两种常见的钙片补充剂：碳酸钙和乳酸钙。

Percent calcium carbonate, calcium citrate calcium 21%, 13% calcium lactate, calcium gluconate Calcium 9

碳酸钙含钙40%，柠檬酸钙含钙21%，乳酸钙含钙13%，葡萄糖酸钙含钙9

Inorganic calcium mainly calcium carbonate, calcium citrate, calcium lactate, calcium gluconate and other classes of organic calcium.

无机钙主要是碳酸钙，柠檬酸钙，乳酸钙，葡萄糖酸钙和有机钙的其他类。

There is no solvent pollution of the solvent free AKD was. It is able to be used in cap paper of foodstuff. The AKD's production method is consecutive. Liquid AKD wax may solve the skidding of paper. The high speed of reaction with fibre AKD wax is used in the light-weight coated paper.

从1956年到1980年期间，AKD等中性施胶剂仅被用于需要重施胶的特殊纸张中，例如，液体包装纸、少量的需要碱性条件下生产的纸等[1]；由于其具有高不透明度、高白度、使用低成本的沉淀碳酸钙填料的优势，同时，许多高档纸开始从酸性造纸转向碱性造纸，自此，AKD进入了快速发展的时期。

They would leave subtle clues in the isotopic composition of the limestone by shifting the ratios of light to heavy carbon and oxygen atoms in its calcium carbonate.

那样会在石灰岩的同位素构成中留下多多少少的痕迹——碳酸钙中碳原子和氧原子的轻重比例会改变。

They would leave subtle clues in the isotopic composition of the limestone by shifting the ratios of light to heavy carbon and oxygen atoms in its calcium carbonate.

因为如果是那样的话，阳光将会被转换成大量的碳、氧原子保存到石灰岩中的碳酸钙里，而事实却是，岩层的同位素组成中没有留下任何蛛丝马迹。

The influence of the change of the pH value and viscosity as well as the impact of aging and adding crystal shape control agents on the crystal shape of nano-sized calcium carbonate in the carbonization process was studied.

研究了碳化过程中粘度和pH的变化，以及陈化和添加晶形控制剂对纳米碳酸钙晶形的影响。

Upscale cigarette paper appropriation calcium carbonate is placed in to lead the position in England, German etc.

高档卷烟纸专用碳酸钙英国、德国等在这方面处于领先地位。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
