矿层

The relationships between the intensity of gamma-radiation and radi- oactive elements content of ore bed have proposed,and made an exhaustive analysis of the various methods solving the uranium content(iteration, inverse matrix and the decomposition suggested by author).

文中提出了比较完整的伽玛强度与矿层中放射性元素含量的关系式，对求解铀含量的各种方法(迭代法、逆阵法和作者提出的分解法)作了详尽的分析，列举了不同类型铀矿床伽玛测井实际资料的电算对比结果。

Because the velocity of the ore bed in the fault trough is different with the velocity of the both sides layers, so for the sake of designing demand we should full use the action of calibrating lithologic character of the refraction wave.

由于在地堑内的矿层和两侧的地层速度不同，为了满足设计要求，在施工过程中，充分利用折射波视速度的岩性标定作用，也就是说根据折射波不同的视速度反映，可以准确判断地震测线是否已控制到地堑的边界断层，并及时调整反射波测线布置，大大缩短了现场处理时间，提高了勘探效率。

In Motuosarla Fe and Mn deposit, the chert mainly distributes in iron ore bed, some on its top and at its bottom, with a relatively stable thickness.

莫托萨拉铁锰矿中硅质岩多分布于铁矿层中，部分分布于铁矿层顶底部位，厚度较稳定。

And that gabbro-diabase is the main ore-bearing horizon.

辉长辉绿岩是主要的含矿层位。

The crystal is plate-shaped, color- less, and transparent, occurring mainly in alkali ore stratum composed of nah- colite.

该矿物晶体呈板状，无色透明，主要产在重碳钠盐组成的碱矿层中。

X-ray diffraction Rietveld refinement results indicate that La2Ni1- y Co y O4+δ compositions have an orthorhombic structure with Fmmm space group. The substitution of partial La3+ with Co at the B-site caused an increase in the length of Ni/Co—O1 bond in the ab plane and La/Sr—O2 bond along c axis.

研究结果表明， La2Ni1- y Co y O4+δ具有正交结构， Co离子取代增加了钙钛矿层中 ab 平面上Ni/Co—O键的键长、岩盐层中沿 c 轴方向上La—O键的键长和非化学计量氧含量，并有利于改善材料的烧结性能。

You can use several mine layers, so that you have to plan your strategy whensweeping through a dense multi-dimensional minefields.

你能够使用若干矿层，以便你必须计划当扫过一密集多维的矿区的时候的你的战略。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
