通过实验研究确定以SrCl_2-SrF_2-SrCO_3的纯锶盐体系作为电解质，实验中还采用了我们最新研制的熔盐电解监控仪对电解过程进行测量和系统的研究，得出以下结论：(1)增加电流强度，反电动势亦随之增加，而升高温度反电动势则有所降低；(2)随着电流密度的升高和电解时间的延长，电流效率逐渐增加，达到峰值后稳步下降；(3)延长电解时间，合金中锶的含量逐渐增加，最高可达18.1％；(4)开始电解后，反电动势逐渐增加，但向熔体中加入SrCO_3后，反电动势明显降低，因此认为在正常电解时是SrCO_3在分解。

结果表明，随着入射角的增加，液晶层的相位调制深度逐渐减小；随着分子倾角的减小，相位调制深度逐渐升高，即随着写入光的增强，加到液晶层两端的电压增加；随着入射角的增加，读出光强的初相位逐渐减小，但该初相位值并不大，即使在入射角10°下达到最大，也仅为0.21π。

The call developmental process of Psittacula agapornis consists of five instinct phases according to its call character. In the first phase （congenital cal1 phase, CCP, 0~12 day of age）, the juveniles only produce single syllable with short syllable length. The second phase（blank-model-forming phase,BMFP, 13~30 day of age） is important for formation of vocal learning pathways. During this phase, the calls characterized by more and longer syllables. In the third phase （call-model-forming phase,CMFP, 31~45 day of age）, the call development is guided by a model system for vocal learning, vocal learning is engendered so that some calls with multi-syllables with UP1 are produced, principal frequency has increased about by 920 cent, the number of note is double that of second phase. The short-term memories are transformed into long-term memories in the forth phase （call-feedback-learning phase,CFLP, 46~90 day of age）. The call of juveniles is a close match to tutor call which accompanied by double various sounds with BS and UP1, and more resonance components were formed. Second principal frequency has increased about by 970 cent, the number of note increases by 2.6~3.0 times. During the fifth phase （excellent call phase,ECP, after 91 d）, vocal motor pathway is developed and the calls are accompanied with most stable, harmonious vari-tone and complex repertoire.

牡丹鹦鹉的鸣声发育分为5个时期。0~12 d为先天性鸣声期，鸣声特征为以基本音为主音的单音节单音调声，声长短。13~30 d为空白模板形成期，鸣声特征为以基本音为主音的多音节单音调声，声长和音量显著性增加，表明发声学习通路开始形成。31~45 d为鸣声模板形成期，鸣声特征为以第1陪音（UP1）为主音的多音节单变调声，声长和音量显著性增加，主音频提升约920音分，涵盖的律音数增加1倍，表明发声学习模板逐渐形成，发声学习开始。46~90 d为鸣声反馈学习期，鸣声特征为以BS和UP1为主音的双变调声，声长和音量显著性增加，主音频涵盖的律音数增加2.6~3.0倍，第2主音频提升约970音分，表明稳定模板逐渐形成，短期记忆逐渐向长期记忆转化。91 d后为完美鸣声期，鸣声特征为以UP1为主音的复合变音调声，声长、音量、主音频的提升和涵盖的律音数都趋于平稳，鸣声稳定而和谐，表明发声运动通路基本形成。

The main peaks of the EEG power spectra were in delta and theta frequency range. In the stage of ethanol exposure, the rats exhibited much more act of attack than the control, the alpha waves of EEG decreased, while the delta waves increased. The EEG power spectra analysis showed the delta power increased and the theta power decreased. In the stage of ethanol withdrawal, the rats showed some withdrawal behaviors such as wet dog shakes, sniffing, groomingand tonic-clonic seizures for audiogenic stimulus. Spikes and spike-slow waves were found in the EEG. In power spectra analysis, the delta power decreased while the alpha and the theta power increased, the EEG frequency band moved to the high-frequency rang. These changes were found obviously on the sixth day and disappeared on the 1 Oth day after the ethanol was removed.
