汞合金

Corrosion behavior of amalgam is affected by different contents of zinc.

银汞合金中锌的含量不同，影响着合金的耐腐蚀性能。

Potential of zinc-containing amalgam was more negative than other alloys,and it was always under anodic behavior during the experiment and was corrupted acceleratedly.

金合金／钴铬合金、金合金／含锌银汞合金、金合金/无锌银汞合金均产生较高的电流值，若存在于口腔中，会有一定危险。

Methods: The color of all veneered samples that were put on noble metal,NiCr alloy,AgHg alloy and resin background was measured with chromatism instrument.

采用色差计测量各组饰瓷后试样在贵金属、镍铬合金、银汞合金和树脂背景上的色度值并计算组间色差值。

So-called dental amalgams , or fillings made with a mix of mercury and other metals, have been used since the 1800s.

所谓的银汞合金或者是填充材料，是用汞和其他材料混合制成的，这种方法从1800年就使用了。

"Dental amalgams contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses," reads a statement that has been added to the agency's Web site.

&银汞合金含有汞，对于成长中的儿童和胎儿的神经系统具有神经毒性作用，&这一段陈述已被加入到该机构的网站中。

Although it is known that small amounts of mercury are vaporized when the fillings are used to chew food, and though Canada, France and Sweden have all placed restrictions on the use of mercury fillings , the FDA has always insisted that amalgams are safe.

尽管知道当填充材料用于咀嚼食物时少量的汞能被蒸发和吸入，尽管加拿大、法国和瑞典都将限制使用汞补牙，美国食品药品管理局还是坚持汞合金是安全的。

Dental amalgams are considered medical devices, regulated by the FDA.Even the FDA's new warning stops short of admitting that dental amalgams are dangerous for the general population.

美国食品药品管理局规定牙齿汞合金是被考虑的医学材料，甚至美国食品药品管理局的新警告拒绝承认牙齿汞合金对普通人是危险的。

METHDOS: Pulp cavity perforations were created in the pulpal floor of 55 extracted tooth. They were repaired with amalgam、flowable resin、Chinese gall compound recipe under amalgam、Chinese gall compound recipe under resin and MTA. Then the sealing ability of different materials by dye penetration were evaluated.

在55个离体牙上制造髓室底穿孔模型后，分别用银汞合金、复合树脂、复方五倍子作屏障银汞合金修复、复方五倍子作屏障复合树脂修复及MTAMTA组）修复，通过染料渗漏法测定各组渗漏情况。

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。
