The hysteresis loops were detected, it is found that the remanent polarization and the conceive field of the ceramics deceased with the dope of ba2 +. in the composition range of mpb, the conceive field exhibit the lowest value
測試了樣品的電滯回線，發現batio _ 3的摻入有效降低了nbt基陶瓷的剩餘極化強度和矯頑場，在準同型相界組成點，矯頑場達到最小值。 -
The properties of all samples were investigated, it is the same to the pzt ceramics, samples in the composition range of mpb exhibited best piezoelectric performance
測試了各組成點樣品的壓電性能，結果表明，與pzt基含鉛壓電陶瓷相似，材料在準同型相界組成范圍內壓電性能最佳。 -
Abstract : inhibition mechanisms of sulphate reduction to methane - producing bacteria ( mpb ) in the process of anaerobic digestion of high - sulphate - content wastewater were described in this paper. they were described mainly by the competition between sulphate - reducing bacteria ( srb ) and methane - producing bacteria ( mpb ), and inhibition of sulfide produced by the microbial reduction of sulphate, meanwhile, the present anaerobic digestion technologies for the high - sulphate - content wastewater treatment were introduced
文摘:本文通過硫酸鹽還原菌和產甲烷菌的競爭、硫化物對產甲烷菌的毒害二方面，論述了在高硫酸鹽有機廢水厭氧處理過程中，硫酸鹽還原作用對產甲烷菌活性的抑制機理，同時，介紹了當前高硫酸鹽有機廢水的厭氧處理工藝。 -
Pms materials have many good properties such as high kp and qm, the good time and temperature stability of resonance frequency, and low dielectric loss at high frequency. pzn materials have excellent piezoelectric and dielectric performances near mpb
Pms材料具有kp和qm高、諧振頻率的時間和溫度穩定性好、高頻下損耗小的特點，而pzn材料則在準同型相界附近表現出優異的介電、壓電性能。 -
Piezoelectric properties were detected, it is suggested that the optimum poling condition is maintaining 15 minutes under 4kv / mm, poling temperature is 70 xrd results indicate that the fabric transited from rhombohedral to tetragonal gradually with the substitution of the ba2 +. morphotropic phase boundaries ( mpb ) of the ceramic exist in the composition range of x = 0. 06 ~ 0. 10
Xrd分析表明，隨著ba ~ （ 2 + ）取代量的增加，樣品晶體結構逐漸由三方相向四方相轉變，在x = 0 . 06 0 . 10組成范圍內存在三方、四方相共存的準同型相界。
