创新型教学模式下高校专业课课堂教学中多媒体技术的应用研究

经过二十多年的发展与普及,多媒体技术广泛应用于高校专业课的日常课堂教学中。目前呈现三个方面的突出问题：师生间缺乏互动、传统课堂教学策略失灵、课堂结构异化。造成这种现象的原因有：教师不具备媒体使用技术、重感性而轻思辨的文化背景、课件编制不适当、多媒体素材形式单一、无法应对移动互联网的挑战等五个方面。文章建议从五个方面着力搞好高校专业课课堂教学：教师应树立正确的多媒体技术观,具备课件制作能力,创新型教学模式,运用移动互联网教学,掌握专业课程教育的方法论。     

极端海况下FPSO系泊系统安全性评估与分析

针对近年极端海洋性气候频发所导致的FPSO系泊系统安全性问题,从服役多年系泊系统钢缆的剩余强度入手,评估影响船体运动的环境参数,给出系泊钢缆的安全系数。利用准静态的方法估算环境等级的范围,选取南海某型FPSO建立系泊系统耦合计算模型。应用AQWA-DRAFT与AQWA-NAUT模块,采用时域非线性方法对系泊系统进行耦合分析,在满足规范系数的前提下确定现服役系泊系统的定位能力,预报系泊系统所能承受的最大风浪流极值组合及对应的台风等级。通过计算可看出钢缆强度的下降直接影响着系泊系统的定位能力,导致其无法抵御百年一遇的台风,系泊系统可抵御台风等级降至12级。     

NH_4Cl薄层液膜下X70钢腐蚀的电化学研究

采用电化学阻抗法和阴极极化曲线法研究了X70钢在含NH4Cl薄层液膜下的电化学行为.研究了液膜厚度、NH4Cl浓度对X70钢腐蚀行为的影响.结果表明,液膜厚度降低,X70钢腐蚀电位正移,阴极极限扩散电流增大.液膜厚度为130μm时,阴极极限扩散电流达最大值.液膜厚度为130~100μm时,阴极极限扩散电流反而降低.液膜厚度进一步减薄,阴极极限扩散电流又增大.薄层液膜下,NH4Cl浓度增大,阴极极限扩散电流减小,抑制了阴极过程;随着NH4Cl浓度增大,X70钢腐蚀的电荷传递电阻减小,对阳极过程有一定的促进作用,从而加速X70钢的腐蚀速率.

廉洁教育进校园要做到“四个融入”——以成都纺织高等专科学校为例

大学生的思想道德修养和职业操守决定了党和国家的前途命运,他们的廉洁意识和防腐拒变的能力决定了党和国家未来的廉政水平和廉洁文化。加强大学生的廉洁教育和大学廉政文化建设具有重要的战略意义。在具体工作中,必须将高校廉洁教育融入课堂教学,融入校园文化建设,融入日常教育管理工作,融入学校制度建设。     

Moral und Abhängigkeit

Definition of the problem:

Being satisfied with one’s work depends on professional autonomy, which is attributed to the medical profession to a high degree, combined with specialized knowledge and moral authority for vital questions. That is why physicians enjoy a high reputation. At the beginning of a person's medical career, moral competence is developed nearly completely, but specialized knowledge must be learned. Hospitals, in which further medical education regularly takes place, are still traditionally hierarchically organized today. Unfortunately, feudalistic or military structures hinder autonomous moral decisions and cause structural irresponsibility.

Arguments:

Obstructions and pressure by superiors, financial restrictions, arrogance and trying to make one's mark are shown in typical conflict situations. Stress, discontent, moral conflicts and illness, even including burn out are possible. Commitment and creativity by employees are prevented and mistakes cannot be constructively managed. Thus, patients may suffer unreasonably or be hurt.

Conclusion:

There is a risk to subordinate moral principles under other interests, not only with subordinates but also with superiors. Ways to create a culture that promotes autonomy among physicians and between different professions are discussed. Therefore it is necessary to institutionalize communication based on a reciprocal high regard in a team with people treated as equal partners, who are then able to discuss moral questions in a discourse.     

X70管线钢在模拟土壤介质中裂纹扩展量化模型

试验研究了X70管线钢在模拟土壤介质中，循环载荷下的裂纹扩展特性和宏观规律．结果表明，裂纹扩展主要受裂尖应力强度因子幅△K的控制；在模拟高pH值(pH=9．3)土壤介质中，加载频率(0．1Hz～10Hz)对裂纹扩展速率无明显影响；在模拟近中性土壤介质中，裂纹扩展速率随加载频率的降低而升高，呈现明显的频率效应．结合裂纹扩展特性，分别建立了X70管线钢在模拟高pH值和近中性土壤介质中，加载频率为0．1Hz～10Hz的裂纹扩展量化模型。
