The existence ofpolar nanoregions dramatically influences the extrinsic dielectric nonlinearityof paraelectric phase. 5 Slow relaxations of field induced piezoelectricresonance of paraelectric barium stannate titanate were observed after eitherapplying or removing a DC bias field. This phenomenon is attributed to slowspace charge dipoles formed by injected homocharges and validated by theobservation of a negative piezoelectric constant. Isothermal study ondielectric constant and discharging current after application or removal of astep field were performed. The relaxation laws in ferroelectric andparaelectric phases are different. The transportation of homocharges arebelieved to be responsible for the strong relaxation behavior in paraelectricphase. Domain wall can trap space charges thus the relaxation in ferroelectricphase is relatively weak. Abnormal phenomena, such as slim-waisted hysteresisloops, abnormal C-V curves and clockwise reversible hysteresis loops observedin barium stannate titanate ceramics, were attributed to pinning of gatheredpoint defect on domain walls.

5研究了直流电场施加和撤除引起的钛锡酸钡顺电相场诱压电谐振慢弛豫现象，认为这是同极性空间电荷注入形成空间电荷慢偶极子导致的，观察到的负压电常数证实了这个观点；研究了等温条件下阶跃电压作用下介电常数和放电电流的慢弛豫现象，发现钛锡酸钡陶瓷的铁电相和顺电相呈现不同的宏观性能时间依赖规律，认为是同极性空间电荷的输运过程导致了顺电相样品呈现强的弛豫行为，铁电相中存在畴壁捕获空间电荷的机制因而其弛豫行为较弱；研究了钛锡酸钡陶瓷中束腰电滞回线、反常 C-V 曲线和顺时针可逆电滞回线等反常现象，将其归因于点缺陷的聚集对铁电畴畴壁的钉扎作用，多次电场循环有助于解除这种钉扎状态，减弱反常特征。

At present, many tall buildings have been built in China because of the constant development of economy, a lot of large-scale civil buildings such as marketplace, office building, industrial building need long-span and heavy load structure. So the traditional prefabricate structure has been already unable to satisfy the constant increasing need because of the shortcomings of short-span and low intensity concrete. If we don"t change the performance of the former prefabricate structure, it will be very swift that the prefabricate structure will be eliminated. Besides, the commodity concrete"s high development, the technology of concrete pump sending popularization and the development of nobonded presterss technology accelerate the shrink of prefabricate structure.

当前，我国由于随着经济的不断发展，高层建筑大量兴起，很多大型民用建筑如商场、写字楼、工业厂房等楼面都需要大跨、重载的楼板结构，因此传统的预制板由于适合跨度小、混凝土强度低等一些缺点，已无法满足不断发展的需要，如不改进原有预制构件的材料性能，将很快被淘汰，而且由于商品混凝土的飞速发展、混凝土泵送技术的推广及无粘结预应力技术的发展更加速了预制构件的萎缩。
