Design on AM-OLED display control ASIC with high gray scale levels

The paper puts forward a method on controlling the AM-OLED panel to display image with high gray scale levels. It also gives an ASIC design sample to implement this method. A twenty sub-fields scan scheme has been taken into use in the chip to display 256 gray scale levels on a QVGA resolution AM-OLED display screen. The functions of image scaling and rotating have also been implemented for multiply application. The simulation and chip test result show that the chip design has met the design requirements.

刚体转动动力学问题中的一题多解

在讨论刚体定轴转动一类动力学问题时,往往有许多不同的解法,可分别用牛顿第二定律、刚体定轴转动的转动定理、动能定理（或机械能守恒定律）、动量定理和角动量定理求解。进行一题多解的训练,不仅可以使学生对动力学有关定理的理解融会贯通,而且可以有效地培养他们的解题能力。     

日本教育公务员制度的特点及其对我国的启示

提高教师队伍的质量是世界各国教育改革的重点。各国教师管理模式主要有三种:公务员,教育公务员及教师专业人员聘用制。目前我国实行的是专业人员聘用制,学术界时有将教师作为公务员来管理的呼声,本文分析了日本教育公务员制度的特点,包括岗位设置、岗位任命、岗位晋级和轮岗制度等方面,探讨了其对我国的启示。     

Validity of the X-factor computation methods and relationship between the X-factor parameters and clubhead velocity in skilled golfers

The purpose of this study was to assess the validity of the X-factor computation methods and to examine whether direct relationships exist between the X-factor parameters and the clubhead velocity in a group of skilled male golfers (n = 18, handicap = ? 0.6 ± 2.1). Five driver trials were captured from each golfer using an optical motion capture system (250 Hz). Two plane-based methods (conventional vs. functional swing plane-based) and one Cardan rotation-based method (relative orientation) were used to compute select X-factor (end of pelvis rotation, top of backswing, ball impact (BI), and maximum), X-factor stretch (stretch and maximum stretch), and X-factor velocity (BI and maximum) parameters. The maximum clubhead velocity was extracted and normalized to golfer's body height to eliminate the effect of body size. A one-way repeated MANOVA revealed that the computation methods generated significantly different X-factor parameter values (p < 0.001). The conventional method provided substantially larger X-factor values than the other methods in the untwisting phase and the meaningfulness of select X-factor parameters generated by this method was deemed questionable. The correlation analysis revealed that the X-factor parameters were not directly related to the maximum clubhead velocity (both unnormalized and normalized).     

发动机缸盖螺栓拧紧方法分析

为了使螺栓达到所要求的预紧力,目前普遍采用扭矩法和转角法进行控制。转角法能够很好控制螺栓的预紧力,可靠性要优于扭矩法。文本阐述了塑性区紧固的依据和实现方法。多次实验后表明,四气门发动机缸盖螺栓采用转角法。     

教师轮岗政策的学校间博弈——从“囚徒困境”到合作博弈

利用博弈理论分析教师轮岗政策的学校间博弈,指出个人理性和集体理性的冲突致使学校容易陷入＂囚徒困境＂。从三个方面可以破解这种困境：一是通过奖励改变博弈的收益矩阵,引导学校走向合作博弈;二是通过明确的制度安排,促使学校通过多次博弈走向合作;三是通过惩罚机制将＂囚徒困境＂转为协调博弈,并通过一定的制度措施使协调博弈向多方获益的均衡转变。
