He experiment proved that pre-implantation embryos are more sensitive than post-implantation ones, suggested TCDD may exert its effect before implantation, or at this process. 3. The toxicity of TCDD on the early embryo can be of omnifarious. It can strongly inhibit DCR, which represent mother toxicity; It cause un-synchronizated cleavage of pre-implanted zygote and pre-implanted embryo loss; It also decreases implantation sites in the uterus, and continued to effecting the uterus of pregnant mouse, cause the decreased number of fetus before birth. 4. TCDD exposure changed reproductive hormone level of pregnant mouse.
CDD对胚胎的毒性影响可能是多方面的:强烈抑制子宫蜕膜细胞反应,表现出典型的母体毒性;虽然没有影响胚胎转运速度,但造成着床前胚胎的丢失和发育不同步;早期染毒降低了第9天的胚胎着床数,同时使出生前第18天胚胎成活数继续减少。

Differing from the feed-back error compensation method, the selflearning error pre-compensation method offered by the paper is based on both ANN and time series technique to obtain the error pre-compensating curve using the non-linear ANN pre-compensation model. Because of the self-learning character of the ANN, this new type of precompensation model can be self-adjusted.
与常规的反馈补偿方法不同,本文提出的自学习误差预测补偿方法,将时间序列预测与神经网络的自学习自适应优化建模技术相结合,利用神经网络非线性预测模型产生误差预补偿函数,并利用神经网络的自学习特性对所建预测模型进行修正,所以这种新型的误差补偿方法能够获得更高的误差补偿精度和控制速度,简单实用,适于推广,具有生产应用价值。

This article discusses the process of teacher education from unity to diversification, and analyses the questions of teacher profession in student selection, pre-job education, practical training, qualification, employ, and on-job education. It recommends 11 improvement strategies as follow: to control severely and to make better demand evaluation, to preserve partly students at government expense to spread excellent mission, to postpone the pre-job education to graduation, to make system and resource soundness in teacher education center, to make the curriculum of pre-job education flexible, to communicate college and school closely, to examine qualification actually, to unitize the teacher employ impartially, to bring the outsider into the teacher arbitration board, to classify teachers, and to found the major on-job education unit drawing up the integrated on-job education system.
摘要本文探讨我国师资培育从封闭一元到多元开放的历程,并从教师专业的角度分析师资培育多元化之後,在甄选学生,职前培育,实习,资格检定,教师聘任,以及进修等方面所遭遇的问题,对於这些问题提出下列十一项改进策略:需要严格把关,并做好需求评估;保留部分师范公费生以传承优良使命;师资培育职前课程应延至学士程度之後;「师资培育中心」制度须健全,资源须充分;职前培育课程必须具有弹性,避免固定僵化;大学与实习学校必须共同规划,密切交流;资格检定必须经过实质审查;聘任的方式必须有一致性与公平性;教评会应考虑纳入外部人士;师资培育多元化须配合教师分级制度;成立专责进修单位,规划整全系统的进修制度,提升教师进修品质。

The samples have lower permittivities by adding MgO before Ba0.6Sr0.4TiO3 powder be pre-synthesized, but have higher tunabilities and lower high frequency losses by adding MgO after Ba0.6Sr0.4TiO3 powder be pre-synthesized. The tunabilities of the samples prepared by adding 15%~25% MgO after Ba0.6Sr0.4TiO3 powder be pre-synthesized are all higher than 20% at 103 V/mm.
