The major works in this thesis are: The effect of the straight and skew cracks on the vibration properties are studied for the cantilever beam, clamped-clamped rectangular plate, simple-supported rectangular plate and triangular plate. The effect on the natural frequency and vibration mode shapes of the bracket in the presence of cracks is discussed Based on the available index of crack diagnosis, a new index, is proposed.

Clean and check 1 slowly loosen the gland nut stuffing, packing the release of residual pressure of all components; 2 Remove all old packing, thoroughly clean axle / rod stuffing; 3 Check the shaft / bar have corrosion, dents, scratches or excessive wear; 4 Check whether there are other WATER POWER CONTROL VALVE parts burr, cracks, wear, they will reduce the packing life; 5 Check whether there is too much stuffing the gap, and the shaft / rod eccentric degree; 6 the replacement of defective parts larger; 7 Check the old packing, as BALANCING VALVES the basis of failure analysis to find the reasons for early failure of packing.

缓慢松开填料函的压盖螺母，释放盘根组件内所有的残余压力； 2）移去所有旧的盘根，彻底清洁轴/杆的填料函； 3）检查轴/杆是否有腐蚀、凹痕、划伤或过度磨损； 4）检查其他零件是否有毛刺、裂纹、磨损，它们会减少盘根的寿命； 5）检查填料函是否有过大的间隙，以及轴/杆的偏心程度； 6）更换有较大缺陷的零部件； 7）检查旧盘根，作为失效分析的依据，球阀以找到盘根早期失效的原因。

The opening of the Ru films have a variety of described, such as the crab claw pattern, ice cracks, onion skin pattern, roe patterns and so on, but I think that using cicada's wings pattern is to describe it appropriately.

对汝瓷的开片有各种形容，如蟹爪纹，冰裂纹，蝉翼纹，鱼子纹等，但我觉得用蝉翼纹来形容是恰如其分。

As the wax film in printing will be bent from time to time arising from the irregular small cracks, stain penetration too small cracks in the cotton dyeing a chic lines, becoming the unique ambience hand batik printed cloth, the traditional ethnic batik printed cloth with indigo dye, printed blue white flower pattern, graphics, mostly birds and flowers and so on, due to differences in habits of various nationalities has its own style.

由于蜡膜在印染时常会被弯折而出现不规则的细小裂纹，染液渗过小裂纹而在棉布上染出别致的纹路，成为手工蜡染花布的特有情调，传统的民族蜡染花布以蓝靛为染料，印出蓝底白花图样，图形多数为花鸟等，因各民族习惯有差别而具有各自的风格。

The ionic space charge in the micro-voids of water tree will produce a period vibration by AC voltage stimulating. Under superposition voltage, the vibration can impel the ion penetrating into the tiny crackle between micro-voids of water tree and lead to a change in the conductivity of water tree. With this the ultra-low frequency spatial current signal of the water tree would be emerged in detecting circuit. The polarization and depolarization of the polar end-group of the PE formed in water tree developing will also contribute to this special signal.

本文分析认为，水树枝中的离子型空间电荷在几种电压共同作用下会发生周期性振动，这种振动会促使水树枝中的导电离子在较低的叠加电压激励下进入连接水树枝微孔的微裂纹，微裂纹导通不仅导致水树枝的电导发生变化，而且在检测回路中会有水树枝老化超低频特征信号电流产生。
