However there are some differences in the learning motivation in terms of different backgrounds:① The higher the academic degree holders, the lower the intensity of the learning motivation in self-development, social contact, family requirement and degree pursuing.② The students from town and villages show great motivation in Better Serving Society, however the students from cities pay more attention to the assessments from family and working company.③The intensity of the motivations in female students in pursuing knowledge, self-development and social contact are apparently stronger than male students.④With the increasing of age, the motivation intensity decreases in the aspects of self-development, career-development and competition or promotion. The students in the age of 40"s to 50"s pay more interests in educating children.⑤The motivation intensity in Better Serving Society, Avoid Failure in The Work and Better Educating Children decreases with the increasing of the income. Middle income class emphases more in promotion.⑥ The intensity of motivation in pursuing knowledge is very strong in state-worker and free-lancer. Teachers pay more attention to career development and the free-lancer emphasis in developing enterprises and self-expressing.

在对比分析中，成人学员因学历、来源地、性别、年龄、收入、职业的不同，其学习动机存在一定的差异：①随着学历层次的升高，成人学员在发展、交往、家庭、文凭动机的多个子项上表现出差异，动机强度依次降低；②县乡学员在"更好地服务社会"项目中比城市学员表现强烈，而城市学员更重视家庭及单位对自己的看法与评价；③女性学员在求知、职业、交往三大类上的动机水平较明显高于男性学员；④在发展、职业、竞争或提升三个方面，随着年龄的增加，其动机强度呈递减趋势，而41－50岁的学员在"为了更好地教育子女"这一项上表现尤为突出；⑤在"更好的服务社会"、"避免工作失败"、"更好的教育子女"三个项目中，随着收入的增加，其强度水平依次减弱，中间收入的学员较其它两层次更在意"得到提升"；⑥不同职业的学员有不同的动机表现，公务员与自由职业者的求知动机表现强烈，教师的职业动机水平相对偏高，自由职业者强调"发展事业"与"表现自己"。

Secondly, in this part, we will introduce the notation of average geodesic curvature for curves in the hyperbolic plane, and investigate the relationship between the embeddedness of the curve and its average geodesic curvature. Finally, we will employ the Minkowskis support function to construct a new kind of non-circular smooth constant breadth curves in order to attack some open problems on the constant width curves for example, whether there is a non-circular polynomial curve of constant width, etc.

Here, we will give an independent proof of the existence for inequality (2.1.3), and by the way, give an estimate on the width of the bi-enclosing annulus of closed convex curves in the plane. Secondly, in this part, we will introduce the notation of average geodesic curvature for curves in the hyperbolic plane, and investigate the relationship between the embeddedness of the curve and its average geodesic curvature.

In combination with the crushed rock slope as an example, the allocation of an anchorage force on longitudinal beams and transverse beams is calculated by adopting the distribution coefficient law of the nodal form at first. Then the internal forces of the lattice beam are calculated respectively through the software on the basis of Winkler elastic foundation model and the semi-infinite foundation model, and then compared with the internal forces which are based on simplified foundation pressure calculation. The active pressure of rock is calculated approximately by Ranking soil pressure theory in the working stage. Sequentially, the reinforcing bars are disposed by two-stage's averagely calculated values.

以破碎岩质边坡为例，采用节点荷载分配法计算了锚索锚固力在格构梁纵、横梁之间的分配比率，然后基于Winkler弹性地基模型和弹性半空间地基模型分别计算格构梁在张拉阶段的内力，并与采用简化的地基反力计算值对比；采用朗肯土压力理论近似计算在工作阶段主动岩体压力，将地梁视为在线性分布力作用下倒置于坡面上的连续梁，按力矩分配法计算地梁内力，取两阶段计算平均值进行配筋。

The physiological effects of fear can be better understood from the perspective of the sympathetic nervous responses (fight-or-flight), as compared to parasympathetic response, which is a more relaxed state.

恐惧的心理影响从交感神经反应的角度可以更好地来理解。与之对比的是处于更轻松地状态的副交感神经。

Some people more pay great attention to music the unified integrity, form a coherent whole, some people more consider the work partial between the difference and the contrast; Some people stress the technical method, some human of deviations music performance.

有人更多地注重音乐的统1完整、1气呵成，有人更多地考虑作品局部之间的差异与对比；有人侧重技术手段，有人偏向音乐表现。

Wary of a crude constitutional change, and keen to avoid unflattering comparisons to the presidents-for-life of central Asian ex-Soviet republics, Mr Putin will find a placeman to stand for president (perhaps the man he just plucked out of obscurity to be his own prime minister, Viktor Zubkov).

由于对粗暴地修改宪法的警觉，也希望避免不受欢迎地与中亚的前苏联国家的终身总统制进行对比，普京将选择一个替代者来代理总统。（也许那个人就是他刚刚已经宣布的他的总理， Viktor Zubkov ）。

This thesis analyzes the types and art trait of solar-assisted heat pump water heater, the development trend of direct expansion solar-assisted heat pump water heater, makes a summary of these research results from six aspects. On the basis of these works and from the point of view of receiving optimum solar radiation , the thesis develops a novel design model of direct expansion solar-assisted heat pump water heater with a truncated cone collector/evaporator, theoretically analyzes the heat that the system can absorb, compares its ability with other two types of cylinder and flat plate ones, and calculates COP and EER with computer aids. The results show that a truncated cone direct expansion solar-assisted heat pump water heater can absorb not only more solar energy but heat energy in air. It takes on favorable thermal performance. Under the average day in February which is of the worst weather throughout the year in Kunming, the COP is about 4. 2, EER is about 2.9 . The heat absorbed by the system are more than those of the other systems. The system is very great in terms of saving

Such calibrated ages, given by CALIB versions, are close to the calendrical true ages in full play. Thus, this is beneficial to better reconstructing the regional geochronologic history since the late Late Pleistocene and such calibrated ages can be compared directly with the archaeological evidence and other absolute dating results as well.
