有困难

The layout scheme design of spacecraft vessel belongs to 3D packing problem with behavioral constraints, and it is also a complex engineering system problems with inscrutability, uncertainty, high nonlinearity, quality and quantity. It is almost impossible to solve it completely by human or computer alone.

航天器舱布局方案优化设计属带性能约束的三维布局优化问题，属具有不确定性、高度非线性、既有定性又有定量问题的复杂工程系统问题，单纯依靠人或计算机算法去解决都是非常困难的。1991年Lenat、Feigenbaum提出的人机合作(Man-Machine Synergy)和同年钱学森、戴汝为等提出的人机结合(Human-Machine Cooperation)思想和方法论，被认为是21世纪解决复杂工程问题的重要途径、自动化设计的重要发展方向，但其可操作性问题一直未很好解决。

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。

China PLA navy usually organize fleet to visit foreign country--for training midshipman or military communication, every year they will made memorial patch and issue to the task force, so far I have got two, but the challenge part is to identify which year, however a good timing is tracking the military magazine like PLA pictorial magazine or news website while their media propaganda.

中国人民解放军海军经常组织间舰队访问外国-培训海军人员或对外军事交流，他们每年都制作纪念臂章并发给参加人员配於制服上，迄目前为止我有两个臂章，但困难的部分是要找出臂章是哪一年制发的，但是有一个很好的时机是追踪军事杂志像解放军画报杂志或新闻网站，当他们的媒体在宣传时。

P×P and P were two major non-Bayesian algorithms. 6 Less than 25% of the participants used frequency. In those who got other results except P , much more people used probability. Experiment 2 had a randomized multigroup posttest design. There was only one factor named implied condition which had five levels: not imply, imply P, imply addition, imply division and imply all. The results showed that: 1 All the implied conditions significantly improved the participants' performance. When under the condition of implying division, the participants derived the best results. 2 31.9% of the participants got correct answer, 73% of who used frequency to rewrite the information. 3 78% of the participants could apply one or several of the four concepts: probability of "not the event", multiplication rule, addition rule and condition probability.

结果表明：1 被试的估计受问题内容的影响，权威型问题情境容易使被试高估，非权威型问题情境使被试的高估现象大大减少；数据结构和提问形式对被试估计不产生影响。2 有近5%的被试能正确估计P，其中 73%使用频数对信息进行再表征。3 贝叶斯推理中各分步骤的困难程度由低到高分别是：乘法、P、加法、除法。4 有50%的被试能运用对立事件概率、概率乘法、概率加法、条件概率这四个概念中的一种或者几种。5 使用最多的两种非贝叶斯算法是P×P和P。6 不到25%的被试使用频数；求得除P以外各类结果的被试中，使用概率的人数远多于使用频数的。

This group all has the cough of different level, the breath after 6 activities is difficult, 5 dry cough, 4 have low heat, night sweat, lack of power wait for a symptom, 1 spits blood.

高楼大厦是越来越多，但地价飞涨，房价腾贵，我只能望楼兴叹，蜗居于自己的斗室；虽然也有自己的蜗居，但所占用的地皮却属于国家，虽说地皮属于国家，但一旦被某个开发商看中了，我的蜗居随时都可能灰飞烟灭、荡然无存；马路是越来越宽了，但自行车道却越来越窄了，原来的专用道，左边变成了机动车道，右边成了无限长方形的停车场，剩下中间窄窄的一条还时常被乱停的机动车占用着；立交桥是一个连着一个，但过马路却越来越困难了，司机师傅连人行横道都不放在眼里，对于乱穿马路的行人当然就是"撞了白撞"；公园绿地是越来越多了，但生活空间却越来越狭小了，原来散步的街心公园被重新绿化、铺上那娇贵的草坪之后，给我们留下的空间，就只剩下一条弯曲的小径了；医院是越来越现代化了，但连感冒之类的普通小病也瞧不起了；歌剧院、歌舞厅、体育馆等，历来就与我们普通百姓无缘，如今竟连电影院也去不起了；九年制的义务教育，如今已是凭出钱多少选择学校，孩子只能从起跑线上就开始"输"给人家了；原来夏天游泳的那条河，如今被砌成垂直上下的岸堤，几十公里没有一个上下阶梯，即使冒险跳下去，但爬上来却已如登天一般；也有一份可以吃饭的工作，但随时都能感受到下岗、失业。。。。。。

We have played difficult opposition and our team has shown they are on a par with the best.

我们有玩了困难的反对派和我们的队以最好有显示他们是在标准上。

Calculous is one of the required courses for non-arts students in vocational and technical institutes. Many students have difficulties in learning Calculous because of the characteristic of the course and basic knowledge level of students, so that the situation of teaching Calculous is not optimistical in vocational and technical institutes. Hence, it is necessary to properly reform the teaching of Calculous in those institutes.

微积分学是职业技术学院非文科专业学生的必修课程，然而由于学科本身的性质以及学生的基础状况，有许多学生对微积分的学习感到困难，使得职业技术学院微积分的教学现状并不乐观，因此有必要对此类学院的微积分教学进行适当的改革。

In the person exactly fresh world, each people all have the pursue tohave the goal, realistic helpless causes how many to be ambitious andthe person is subdued by the brutal reality, in the person way out theunavoidable meeting difficulty and the setback, the key looked howfrom has faced Some people encounter the setback, because expectedtoo high threw down the heart to pay attention to the out of trim,sighed the reality all day long helpless, the destiny unfairlyActually did not know was oneself from has pushed to the helplessabyss Some people facing the similar question also are can at a loss,why but can he be calm analyzes is defeated, how again faces shouldtreat!

人活生世界上，每个人都有追求有目标，现实的无奈致使多少雄心勃勃和人被残酷的现实折服，人生路上难免会的困难和挫折，关键看自已如何面对。有人遭到挫折，因期望太高摔倒了心理会失去平衡，终日感叹现实的无奈，命运的不公。却不知是自己把自已推向更更无奈的深渊。有的人面对同样的问题也是会茫然，但他会冷静下来分析因何失败，再面对该如何去对待！
