The possible reason is that in shock waves a nonstoichiometric ferromagnetic zinc ferrite is formed, in which the distributions of the cations in the A and B sites of the sublattice are different from that formed in calcination, it has stronger exchange interaction and leads to the increase of the magnetization.

可能的原因是冲击波合成了非化学计量比的铁磁性铁酸锌，改变了尖晶石次晶格中A，B位阳离子的分布而使其具有更强的交换相互作用而导致其磁化强度的增加。

The results showed that:①the crystalline phases are mainly the cuspidine, wollastonite and gehlenite with nepheline, fluorite and olivine also found in some samples under the experimental conditions;②with the bacisity and CaF_2 content increased, crystalline proportion of mold flux rises .

熔融保护渣在MoSi2高温电阻炉内以2℃/min降温速率冷却至室温，制成薄片，采用岩相显微镜分析保护渣的结晶矿相·结果表明：在本实验条件下，结晶矿相主要有枪晶石，硅灰石，黄长石，个别渣样有霞石，萤石，橄榄石；增大保护渣碱度，能促进保护渣结晶；随着渣中CaF2，Na2O，K2O和Li2O质量分数的增大，保护渣结晶化率增大；随着渣中Al2O3，MgO，BaO和MnO质量分数的增大，保护渣结晶化率减小

The thermal shock resistance of the brick is expected to improve as a result of bigger bulk density, lower thermal expansion coefficient, phase transformation of fused MgO-ZrO2 eutectic powder, formation of magnesiaalumina spinel and forsterite.

材料性能的变化主要与电熔MgO-ZrO2共晶砂的体积密度大、热膨胀系数小、氧化锆的相变、镁铝尖晶石和镁橄榄石等物相的生成相关。

The results show that higher zircon addition resists the densification of fused magnesia zirconia materials,and the zircon addition influences the crystalline size of periclase,pore size and the pore structure significantly.

结果表明，配料中锆英砂含量的增加使熔浆的粘度上升，合成料难以致密化。锆英砂配入量对ZrO2晶形及晶粒尺寸影响不大，但明显影响方镁石的晶形、晶粒尺寸以及气孔的形状和尺寸。

At first, mineral composition and distributing of impurities in andalusite grains were studied by SEM and EDS. The results showed that main mineral impurities were biotite, ilmenite, clay species, the wall rock conglutinated at brim of andalusite and impurities in the chiastolitic cruciform pattern were easily removed, but the small impurities in andalusite grain were hardly removed.

首先，利用SEM和EDS分析了红柱石矿的矿物组成和杂质分布，结果显示这种红柱石矿所含的杂质矿物主要是黑云母、钛铁矿和黏土矿物等，其中分布在红柱石颗粒边缘的围岩和空晶石内的黑十字容易去除，而分布在晶内的细粒杂质则不易去除。

The smooth and uniform calcium carbonate whiskers with aspect ratio 30-60 were produced without any additive, and the special branch-like calcium carbonate crystal was also prepared surprisingly. Furthermore, the mechanism for the calcium carbonate whiskers growth was discussed.

在未添加任何添加剂的情况下，成功制得长径比约30～60、表面光滑、大小分布均匀的文石型晶须及形貌独特的树枝状晶体，并对晶须的形成机制进行了分析。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
