To inestigate further, Dr. Fifer and colleagues examined surgical specimens from four patients who had undergone septal myectomy as long as 14 months after unsuccessful alcohol ablation.

Based on the prior information obtained by qualitative inversion, the two stages inversion method was put forward. That is, the first stage is that distinguishing the high-quality element and non- high-quality element, and determining the initial iteration value of element sound velocity reasonably. The second stage is that treating differentially the constraint weights of the high-quality element and non- high-quality element, and then quantitatively inversing the final sound velocity distribution. The results of two concrete specimens indicate that the two stages inversion method can inhibit artifacts effectively and has better defect identification effect than normal one stage inversion.

在获取定性反演先验信息的基础上，提出了两阶段反演的方法：第一阶段，区分优质像元和非优质像元，合理确定像元声速的迭代初值；第二阶段，区别对待优质像元和非优质像元的约束权重，定量反演最终的速度分布。2个混凝土试件的模型试验表明，两阶段反演能有效抑制伪像，具有比常规的一阶段反演更好的缺陷识别效果。

The specimens may not burn with flaming combustion for more than 30 seconds after either application of the test flame.

在每一次本生灯火焰燃烧1 0秒钟移开后没有任何一个试片被火焰点燃超过30秒钟。

The specimens may not burn with flaming or glowing combustion for more than 60 seconds after the fifth application of the test flame.

在第5次的火焰燃烧5秒钟之后，没有任何一片试片被点燃或持续燃烧超过60秒。

The specimens may not have glowing combustion that persists for more than 60 seconds after the second removal of the test flame.

没有任何试片在第二次测试火焰移开后燃烧持续超过60秒钟。

When a specimen of a thin material shrinks from the flame without igniting,the test results shall be deemed invalid and additional specimens shall be tested.

当一个薄材料样件在没有点燃的情况下遇火焰收缩时，应认为测试结果无效，应使用其他样件再次测试。

A writer has found a small deposit of manganese ore and rock specimens flecked with uranium or stained green by copper.

一名作家还发现了一个不大的锰矿堆积体和一些粘染有铀痕迹或者带着铜绿斑痕的矿石标本。

To evaluate the bioactivity of the glass-ceramics,the specimens were soaked in the simulated body fluid. The results indicate that fluorapatite shows needle-like microstructure, which is similar to that in human bone and teeth. The formation of needle-like fluorapatite is related to the heat treatment procedure, which results in needle-like fluorapatite crystals by accelerating one-dimension growth along the c-axis through the screw dislocation growth mechanism. The mechanical properties of the glass-ceramics are close to those of the human bone and teeth. The bioactivity test results show that apatite layer is precipitated on the materials surface after 3 d immersion in SBF, which indicates the glass-ceramics have a good bioactivity.

研究结果表明：氟磷灰石相呈针状，与人体骨和牙齿的磷灰石形貌相似，有利于提高材料的生物活性和生物相容性；氟磷灰石的形成是材料被迅速加热至高温进行热处理，使磷灰石以螺旋位错生长机制沿c轴晶化长大所致；经热处理获得的材料具有优良的力学性能，基本满足骨科和齿科用生物材料的性能要求；材料在体外模拟体液中浸泡3 d后，样品表面已有磷灰石层生成，表明该材料具有较高的生物活性。

The artery in the edge of lens capsule equator department started atresia and vanishing at the 30th week, and vanishing complete at the end of the 32nd week in some specimens. Up to the 33rd week, two group artery of different origin were complete atresia and vanishing, were remaining the transparent vitreous body frenum.
