晶石

It was then topped off with 3 thin coats of spar.

这是当时超过了与3晶石薄外套。

Significantly, these mines were not very far from the lapis lazuli and spinel ("Balas Ruby") mines in Badakhshan and, although separated by the formidable Pamir mountains, routes across them were, apparently, in use from very early times.

值得注意的是，尽管是被高大的帕米尔山脉所分隔，但是这些矿场离巴达赫尚的青金石和尖晶石矿场并不遥远，显然地，横过它们的路线在非常早的时候就已经使用。

In 1851 authorities discovered that it is actually a spinel.

当局在1851年发现，它实际上是一个尖晶石。

Spinel is a beautiful stone that comes in many colors.

尖晶石是一个美丽的石头，在许多色彩。

However, at a relatively high temperature NiAl2O4 spinel is generated.

而在相对较高的温度下生成NiAl2O4尖晶石。

Some methods to reduce capacity fade and the development of the spinel Li-Mn-0 are proposed.

提出了减少容量衰减的几种方法，并对尖晶石Li-Mn-O的发展作出展望。

Recently, and new type of spinel has been discovered.

最近，新型尖晶石被发现。

For some time the spinel was almost put on a shelf, and not much attention was paid to it.

对于一些尖晶石几乎货架上花了不少时间，并没有多少注重它。

The effects of each additive on sintering and properties of NiFe_2O_4 spinel were investigated.

研究了各种添加剂对烧结及NiFe_2O_4尖晶石性能的影响。

As the result,the research on the relationship between the properties of spinel ferrites and the corresponding preparation processes is quite important.

因此，研究尖晶石铁氧体的制备过程对其性质的影响就显得十分重要。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
