In the study of microwave sintering of BaTiO〓 PTC ceramics, when the applied microwave power are above than a certain value, the abnormal axial shrinkage of the sintered sample will occur, by the analysis of SEM and XRD, it is found the microstructure and phase are different with conventionally sintered sample, the reason for this phenomenon is due to orientational grain growth by the action of electric field in the microwave sintering process.

微波烧结BaTiO〓电子陶瓷时，当所加的微波功率超过一定值时，首次发现烧结样品出现轴向异常收缩现象，采用SEM、XRD等分析发现其微观结构与常规烧结有巨大的差异，这是BaTiO〓材料的晶粒在微波场中受电场力作用而发生的取向生长造成的。

They can occur in any part of the body where the cells multiply abnormally.

他们可以发生在身体任何部分如细胞繁殖异常。

Abstarct:The rate of attack of milk cow's abomasum shift is high.If we can not diagnose in time and give the treatment early.The great damage will be occur to milk cow industry.The wirter did 100 cases clinical diagnosis and treatments in Ya An.It shows that surgical operative treatment is the best instauration way.

奶牛真胃移位发病率高，如不及时做出诊断并给与治疗，该病会给奶牛业带来极大的损失，笔者通过对雅安地区100多例奶牛真胃移位的临床诊疗实践证明，奶牛真胃移位最有效的疗法是手术整复疗法。

Despite the assistance, he says civil rights abuses continue to occur, including "voluntary interviews," the Absconder Apprehension Initiative and the Special Registration Program.

尽管援助，他说，公民权利的行为继续发生，包括"自愿采访，"潜逃逮捕倡议，并特别登记计划。

From the industry to observe,the author discovers that the regional gap of the secondary industry was the primary contributor,but the rate of was descending.The third industry was becoming the important contributor.The industry structure adjusting and the agglomeration of the third industry and the secondary industry are the primary reason of the forming of the disparity of between the east and the rest areas.In the 1978 to 2005,the absolute convergence of economic growth didn't occur,the other way round,the club convergence of economic growth occurred in the east and in the middle.The speed of the economic growth in the east was higher about 1 centigrade than the middle and the developing west,and was higher about 2 centigrade than the west.

从以省区为单元的中国地区经济发展差距形成的产业构成来看，第二产业的地区差距长期以来都是中国地区经济发展差距的主要贡献者，居主导地位：但是随着第三产业产值比重的提高和第三产业地理集聚的非均衡性扩大(1990年以后)，第三产业的地区差距正逐渐演变为以省区为单元的中国地区经济发展差距形成的主要贡献者。1978-2005年期间，中国地区经济增长并没有出现绝对收敛趋势，而是表现为东中部地区内部的"俱乐部"收敛。1978-2005年东部地区经济增长速度比中西部地区更快，东部地区平均经济增长速度比中部地区高1个百分点左右，比西部地区高接近2个百分点，地区间经济增长速度存在显著的差异。

However, operating of the high current, the output power, gain, and efficiency of gyro-TWT will be degraded where the absolute instability, gyrotron backward oscillation and reflective oscillation occur to cause mode competition. Stability issues comprise the key factors limiting the performance of the gyro-TWT.

对於高电流的影响，磁旋行波放大器将有可能引发绝对不稳定、磁旋返波振荡(gyrotron backward oscillation；gyro-BWO)及反射振荡，造成模式竞争而抑制原先操作模式的放大波，进而影响其输出功率、增益及效率。

The basicflows are computed by a low-dimensional Galerkin method.The results confirm thattwo times global mode switching occur with increasing Re up to which the Hopf bifur-cation occurs when the absolutely unstable region cover the whole reversed flow region,and the first explanation of this phenomenon with absolute/convective instability theoryis given.

结果证实了只有当绝对不稳定性区域完全覆盖了回流区才会形成整体的Hopf分叉，此前随着Re数的增加整体模态经历了两次跳跃；并首次用绝对/对流不稳定性理论解释了这一现象。

However, operating of the high current, the output power, gain, and efficiency of gyro-TWT will be degraded where the absolute instability, gyrotron backward oscillation and reflective oscillation occur to cause mode competition. Stability issues comprise the key factors limiting the performance of the gyro-TWT, therefore physical origins of spontaneous oscillations in the gyro-TWT are analyzed and characterized.

然而受限於操作高电流，磁旋行波放大器可能引发绝对不稳定性、磁旋返波振荡(gyrotron backward oscillation；gyro-BWO)及反射振荡，造成模式竞争而抑制原先操作模式的放大波，进而影响其输出功率、增益及效率。
