硼镁铁矿

The strength of suanite and szaibelyite are low. The strength of ludwigite is high, but its reducibility is low.

遂安石和硼镁石的强度较低，硼镁铁矿强度虽高，但还原性差。

ABSTRACT Agglomeration mechanism of ludwigite agglomerate is studied systemly. On the studies before, compound additive containing B and Mg is explored and expanded.

深入系统地研究了硼镁铁矿造块的固结机理，并在已有研究的基础上探索和开拓了含硼含镁复合添加剂。

Ludwigite, suanite, szaibelyite, magnetite and hematite are made artificially. Their forming condition, strength and reducibility are studied.

用人工方法合成硼镁铁矿、遂安石、硼镁石、赤铁矿、磁铁矿，以研究它们的形成条件、强度和还原性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
