Researcher who held the post of the media literacy lecture for the past three years, discover through the interaction with the teacher who join the seminar or the teaching team who need the counseling, it's not easily to implement media literacy in the school, lay in the teacher to be insufficient regarding the media elementary knowledge, causes to be unable independently to design the teaching activity, however in the market although had few publications to be allowed to instruct the media literacy teaching, but in the teaching activity often needed to use the massive media model, those had to collect by the teacher voluntarily, moreover most of these curricula taken the independent teaching, didn't intergrade and coordinated with the existing curriculum, therefore could have the problem in the teaching time.
研究者以三年来担任媒体素养研习讲师,与参加研习的教师和寻求辅导的教学团队互动的经验中发现,不易在教学现场实践媒体素养教育的原因,在於教师个人对於媒体的知识基模不足,以致於无法自行设计教学活动,而坊间虽有极少数的出版品指导媒体素养教学,但教学活动中往往需要用到大量媒体范例,必须靠教师自行搜集,而且这些课程多采独立教学,并非配合现有学科进行融入教学,所以会有教学时间的困难。

Amur tigers had a copulatory pattem with no lock,thrusting, multiple intromission,and single ejaculation,which belonged to copulatory pattern No.11 in Dewsbury\'s copulatory-patterned system.5 The behaviors that accounted for most of the total time budget during the parturition period were grooming,lying and licking kittens,26.90%,26.23%and 23.83%,respectively.
东北虎的交配模式属于Dewsbury分类系统中的第11种,即无锁结、有抽动、单次插入、多次射精。5在分娩过程中,雌虎的梳理、卧息和舔仔行为时间最长,分别为26.90%、26.23%和23.83%;梳理、努责和舔仔行为发生频率较高,分别是37.95%、18.75%和12.50%。6在育幼过程中,雌虎室外期与室内期哺乳和亲仔行为的时间差异极显著(P<0.01),离开行为的时间差异显著(P<0.05)。

Presents the design of longitudinal control for ASTOVL lift-fan aircraft, a multi-variable, strong-coupling, complicated nonlinear system to make the system nonlinear offset and decouple, and the method used for linear system in designing the system to gain expectant flying qualities and the combination of aerodynamic control surfaces with thrust vectors to delay the control surfaces getting into saturation, and the minimum N-norm generalized inverse theorem of weighted generalized inverse adopted to apportion the moments commands, which make the control surfaces gain appropriate deflection and the simulation results to verify the dynamic inverse control laws designed really make the system nonlinear offset and decouple; when one command is given, only this output will response, and others do not response; when all commands are given together, the responses will be just the linear superpose of the response of each command, therefore the operation of the pilot will be simplified greatly.
摘 要: ASTOVL升力风扇飞机是多变量、强耦合、复杂的非线性系统,采用非线性动态逆理论设计控制律以实现系统的非线性对消及解耦,然后,采用线性系统的设计方法对系统进行设计,以使系统获得期望的飞行品质。同时,考虑到ASTOVL升力风扇飞机是由气动舵面和推力矢量融合作用的,为了延缓各舵面进入饱和的时间,采用加权广义逆中的极小N-范数广义逆定理分配力矩指令,从而使各舵面达到适当的偏转角。并将所设计的控制律进行了仿真,结果验证了所设计的动态逆控制律使系统实现了非线性对消和解耦,单个指令作用时,只有该项响应,其余不受影响;所有指令作用时,其结果就等于单个指令作用时的线性叠加,这样使驾驶员的操纵大大简化而易于控制,从而大大降低了飞行事故率。
