A novel layout of IC transformer is proposed to achieve both high turn ratio and coupling coefficient in this paper. In order to discuss the coupling coefficient, the layouts are designed with different turn ratio. The thesis is mainly includes of three experiment topics. The multi-stack structure is proposed to achieve prior goal in first topic. Two groups of proposed devices are designed to maintain identical self- inductances in transformer's primary and secondary coils. Total six devices are fabricated in foundry 90-nm CMOS technology. Using the 9 and 5 metal layers in primary and secondary coils in a specific layout, measurement results show that the transformer has the largest benefit using the bottommost return layer in layout design. In one word, the adoption of more metal layers to construct different turn ratio transformer shows not only improving the N value but also saving the chip area in this experiment.
中文摘要本文是针对不同圈数比变压器探讨其耦合量的变化,并且期望其变压器能同时达到高圈数比及高耦合系数的特性,本论文主要可分为三个实验主题,首先第一个主题提出以90nm CMOS制程技术实现的多层金属层的布局方式,并以相同的一、二次侧自感值分为两组,利用不同返回层来达到不同的圈数比,且从量测结果可以得知,在变压器布局设计上使用最底金属层来作返回层会得到较好的特性,最后从此实验得知一结论,利用合适的多层金属架构达到不同的圈数比,不仅可以改善圈数比,还可以缩小晶片面积。

There is a small action range in archery.Simple methods and analysis is inadequate,so the author,on the basis of testing the archery athletes in national team with the Qualisisy infrared photoelectric testing system,Footscan sole pressure testing system,Noraxon myoelectricity remote testing system, etc,analyzes comprehensively the action technique of the athletes in national team from the posture,body motion characteristics,body posture equilibrium and stability,distribution of centre sole pressure, myoelectricity characteristics,etc,with the methods of relative software and data statistics.The conclusions and the suggestions are as follows:Conclusion:Firstly,the communality of posture angle,muscle strength,the activation order of main muscle during raising the bow, raising the bow and the timing of the raising could be used as the evaluation index of technique action in archery;Secondly,the length of the time needed in the different periods couldn\'t be used as technique evaluation index since it has no relation with the result.But the time of raising and pulling back the row is relatively fixed,and the time has a positive relation with the archery achievement of the national team in China.Thirdly,the central index of the sole pressure could be used as the reference criterion of selecting athletes and forecasting achievement.During playing archery,the interrelation between the central index of the sole pressure and the achievement is different individually and in different periods.Fourthly,there is low stability of the archery athletes in the front and back direction during the action, caused by the athletes\' posture disequilibrium of dorsal abdominal muscle and non-professional sport shoes..Fifthly,kinematics and electromyography shows that the people on archery in China haven\'t taken the raising and pulling back the row seriously.
射箭的肢体动作幅度小,简单的手段和分析不能满足其需要,笔者结合各种运动生物力学仪器优点及射箭项目的特性,选用Qualisisy红外光点测试系统、Footscan足底压力测试系统、Noraxon肌电遥测系统等对国家队射箭队运动员进行多方位的测试,运用相关软件及数理统计方法,对运动员的射箭动作技术,从射箭动作的姿态构架、肢体运动特点,身体姿态平衡稳定性、足底压力中心分布、肌电特性等进行全面分析,结论及建议如下:结论:第一,姿态角、肌肉用力激活程度、举弓阶段主要用力肌肉激活顺序、举弓、开弓时间等的一致性可作为射箭技术动作评价指标;第二,各动作阶段所用时间的长短不能作为技术评价指标,但举、开弓的时间相对较固定,开举弓时间比与中国国家队射箭成绩正弱相关达到显著性;第三,闭眼状态下足底压力中心单位面积轨迹长与144支箭最好成绩正相关达到显著性,可作为身体素质、选材及成绩预测的参考依据;实射时身体平衡的足底压力中心指标与成绩的相关程度具有个体性差异、阶段性差异;第四,射箭运动员实射时身体在前后方向上的稳定性较差,这与运动员的站立姿态、腹背肌力量的不匹配以及射箭没有专业运动鞋有关;第五,运动学及肌电学都表明中国射箭训练对举弓、开弓阶段的重视不够,背部肌肉用力特征不明显,撒放技术合理性不高。

We try to find out more methods to releasing pressure and its probabilities to provide design circles or the related toy manufacturers with guidelines and opinions.The study result showed that Healing toys can be separated into five types, the type that is a personification in vision for appreciation purpose, the type that is controlled by the human voice and can interact with people, the type that can make an action by theuser's touch control for entertainment purpose, the type that is sensitive to the light and reacts with regular actions, and the type that contains IC chips and has some kinds of artificial intelligence. Through three rounds of Delphi method, we knew that the word "Healing" was named because the healing toys can soothe, relieve and transfer the strong pressure inside somebody's mind. The characteristics of those toys are having cute appearance, harmlessness, tenderness, lovableness, two-way interaction, addition function that can give surprise, and relationship related with emotions of oneself.The concrete feelings given by the healing toys are happiness, relaxation, reducing pressure, transferring attention, deferring bad moods, and having the power to change emotions. Besides, the healing toys are considered suitable to be assisting materials to heal somebody's mind by playing games because it has characteristics of helping to transfer or relieve negative emotions and helping to transfer attention. The questionnaire results from Mature age generation indicated that the most favorable, healable and desirable toy is the type that contains IC chips and has some kinds of artificial intelligence; and the type that is a personification in vision for appreciation purpose is in contrast. Considering the related perspectives toward the healing toys, people of Mature age generation mostly agree the expert, Delphi for his viewpoints.

The conclusions were as follows: theνO-H andνC=O IR absorption maxima shifted towards higher wave numbers after imprinting 17β-estradiol on TFMAA-co-TRIM copolymer with the red shift of theνO-H groups being apparent after precipitation polymerization for 16h while that forνC=O groups being observed after polymerization for 24h. A strong interaction between TFMAA and 17β-estradiol was confirmed by the high selectivity for 17β-estradiol, as indicted by the values of the separation factor of isomers of 17β-estradiol/17α-estradiol (2.28) and the imprinted factor (3.01). Particle diameter of TFMAA-co-TRIM polymer was between 300 nm and 1.5μm, which suited well for solid phase sorbent throughout at low column pressure. The recognition of imprinting TFMAA-co-TRIM polymer for sterol molecules was driven by enthalpy eluted with acetronitile, and low temperature was in favor of the separation of sterol structure analogues on imprinting column. TFMAA-co-TRIM polymer possessed of determinate anti-heat stability, with melting point beginning at 255.84℃, Tp=257.40℃, control TFMAA-co-TRIM polymer and imprinting TFMAA-co-TRIM polymer were respectively decompounded at 267.79℃and 343.11℃, and solid micro-extraction noddle prepared by the special polymerization also showed definite recognition for 17β-estradiol by GC/MS detecting at 270℃. By selection of various washing and elution solvents, elution reagents of close polymerization system were of more advantage in template molecules retention and recognition on molecularly imprinted solid phase extraction column. At a certain extent, progesterone, 17α-estradiol, 17β-estradiol and 4-androstene-3, 17-dione could be intercepted on the MISPE column. Especially, MISPE had high selectivity for progesterone, and imprinting TFMAA-co-TRIM polymer could achieve adsorption balance within 50 min by absorption kinetics test for 17β-estradiol. However, MISPE column showed better selectivity and enrichment property for 17β-estradiol than C18 and CSPE columns according to the data from HPLC and GC/MS analyses. Recovery of 17β-estradiol on MISPE column was up to 85.5% while when prime extracting solution of milk powder was sampled, the recovery of CSPE and C18 columns were 43.7% and 30.7%, respectively.
