In comparison with the sample directly sintered at 650 ℃＜TN, an interesting, irreversible transformation in the crystal structure of the MgB2 phase is observed with the sample going through the stages of initial sintering at 750 ℃, then re-sintering at 650 ℃ in an Mg-rich environment after the processes of regrinding and pressing.

把直接在650 ℃＜T N，烧结的样品与先在750 ℃下烧结，之后又再次重磨和处理后，并于富镁的环境中在650 ℃下再烧结处理的样品相比较，观察到了MgB2的不可逆的晶体结构转变。

The results shows that the flow characteristics of SiC-AlN granulated powder is obviously promoted after spray drying and a suitable particles grade match. With the increasing of pressure, the density of green body increases by the style of ladder at the pressure range of 4080 MPa, 80160 MPa and 160220 MPa, the green body is uniform and densification without hard pelleted particles above 160 MPa. The pressureless sintering SiC-AlN multiphase ceramic possesses superior sintering properties and mechanical properties. It is due to the rampart formation of AlN to SiC grain growth and the reaction of SiC and AlN to form 2H solid solution. It results in the grain fining, crack expansion producing bypass and deflection, fracture section producing tearing-open and pulling-out effects, which cooperatively improves the strength and fracture toughness of the multiphase ceramics.

结果表明：喷雾造粒后，复合粉体的流动特性显著提高，粒度级配合理；随着压强增加，坯体密度在40~80、80~160和160~220 MPa范围内呈现阶梯式增长，160 MPa以上成形后素坯均匀致密，无硬球颗粒存在；无压烧结SiC-AlN复相陶瓷具有优越的烧结性能和力学性能，这是由于AlN对SiC晶粒形成生长势垒，并反应生成2H型固溶体，从而细化晶粒，导致裂纹扩展产生了绕道与偏转效应，呈现晶粒撕裂与拨出现象，协同改善了复相陶瓷的强度及断裂韧性。

A historical region of southwest France between the Pyrenees and the Garonne River. The duchy of Aquitaine was joined with France after the marriage of Eleanor of Aquitaine to King Louis VII in1137, but its possession was disputed after her subsequent marriage to Henry II of England.

阿基坦法国西南部一个历史地区，位于比利牛斯山和加隆河之间，在1137年阿基坦的埃莉诺与国王路易斯七世结婚之后阿基坦公国加入法国，但当她再嫁英国亨利二世后，其归属权便受到争议

There are moments when I look at the smiling , happy faces of my expectant staff and wonder how they will cope when confronted by an outraged housemaster along with an unrepentant and recalcitrant bleached blond teenager in 18 years ' time .

有时候，我看着那些满怀期待的员工微笑，幸福的脸，想着当他们遇到一位愤怒的宿舍管理员和一位不知悔改，叛逆，而且将头发染成白色的18岁少年时，他们会如何处理。
