There were no bone erosion in the 3 ears with simple type otitis media, and the 19 ears with cholesteatoma showed: abnormal soft-tissue and bony erosion in the tympanic cavity and antrum; dislocation and disruption of the ossicular chain; and showed disruption of sigmoid sinus plate, tegmen tympani, semicircular canal and facial nerve canal in severe cases.

胆脂瘤型中耳炎SCT-3DI示：鼓室、鼓窦内软组织影和骨质破坏，听骨链移位和破坏，严重者破坏鼓室盖、面神经管、外半规管和乙状窦板等，与手术中所见基本相符。

The comparative investigation of the characteristics of deformation and AE were conducted and the results are presented as followed: 1. The characteristics of rock AE are correlated to the strength, joints, cracks, and the size and hardness of crystalline grain. 2. The sequence of AE can be divided into four phases: beginning phase, tempestuousness phase, drop phase and dreariness phase. The loss and the duration of the phases are correlated to the rock character and flaws in the rock. 3. The AE rate characteristics are not almost concordant with the AE energy rate. 4. Besides the homogeneity, the strength of rock contributes the activity of AE. The higher the strength is, the lower the activity is. 5. There is a dreariness phase before the failure of most kinds of rock. 6. Whether the precursor is obvious is correlated to rock the character, and the precursor of AE rate is more apparent than the precursor of AE energy rate comparatively.

通过对比研究这六种不同岩石的变形和声发射特征发现，岩石声发射受到岩石强度、节理裂隙和晶粒软硬大小等的影响；岩石声发射过程存在初始区、剧烈区、下降区和沉寂区，各个阶段是否存在及持续时间与岩石强度、内部缺陷等有关；岩石的声发射事件率特征与能量率特征并不完全一致；岩石的声发射活性除了受其均匀性影响外，还受到岩石的强度影响，强度越小，声发射活性越强；大多数岩石破坏前存在一声发射沉寂区；岩石的破坏前兆是否明显跟岩性有关，相比较而言，岩石破坏时的声发射率前兆比声发射能量率前兆更为明显一些。

Considering the difference of earthquake intensities in both sides of the fault zone, artificial earthquake waves were simulated by trigonometric series method with different seismic peak accelerations. Then the seismic failure numerical analysis was carried out, the weak areas of seismic failure and their reasons were discussed particularly.

考虑到断裂带两侧地震强度的区别，采用三角级数法模拟人工地震波时选用不同的地震峰值加速度，然后对其进行地震破坏数值分析，重点讨论了桥梁地震破坏的薄弱部位及其破坏原因。

Fractography analysis shows that the global tension failures trimly,because of matrix cracks and tension fracture of fiber and the compression specimens failure in a shear plane about a little angle to the compression loading direction because of delamination and longitudinal fiber shear fracture.

其拉伸断口较为平齐，基体开裂以及纤维拉伸断裂是主要破坏形式；压缩破坏呈现剪切断面，压缩断面和压缩加载方向形成一个较小夹角，层间分层和纵向纤维剪切断裂是其主要破坏形式。

环境问题破坏了人们的生存环境，损害了身体健康，降低了生活质量；由环境问题所引起的纠纷、投诉和群体冲突影响了社会的稳定；更为严重的是，生态环境的破坏将使国家和民族失去生存条件和发展基础，由此引发的生态灾难对国家安全所构成的威胁甚至比传统的战争破坏更加可怕；环境问题已成为21世纪战争与冲突的导火索和国际政治斗争的焦点，危及国家的安全。

It is indicated that loosely compacted soil is of strain-softening behaviour under undrained conditions, accompanied with a rapid increase in excess pore water pressure. In anisotropically consolidated constant shear stress tests, a very small axial strain was required to induce the failure and the excess pore water pressure increased quickly at failure.

研究表明：松散填土在不排水条件下具有应变软化的特性，软化过程中伴随着孔隙水压力的迅速上升，有较高的液化势；在常剪应力排水剪条件下，具有破坏前轴向应变小、破坏时间短，破坏过程中孔隙水压力迅速上升。
