硼化物陶瓷材料

By means of the analyses of SEM and metallograph and physical tests,the microstructure and properties of the composites made from copper-coated-TiB2 have been studied.

1引言硼化物陶瓷具有极高的熔点、高化学稳定性、高硬度和优异的耐磨性，基于这些优点，成为复合材料强化物的首选材料之一。

Various grinding machine components are made of superhard materials, including certain machine grade ceramics, including such materials as carbides, nitrides, borides, oxides, oxynitrides, or any other ceramic component.

由超硬材料制造的各种磨床部件，超硬材料包括某些机械等级的陶瓷、诸如碳化物、氮化物、硼化物、氧化物、氧氮化物或任意其它陶瓷组分的材料。

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。
