John Updike has been an acute observer of human conditions.Social conformity and individualism is a pair of collision.To be submissive or rebellious determines the direction of the protagonist’s growth and a forward looking sight of hope on younger generation.By depicting such conflict,Sammy in "A & P" undergoes a short but hard spiritual maturation. 相似文献

Yesterday evening, I went to see a play. It was really significant. It was about Zheng Xiaoyue, a very clever and diligent middle school student. Unfortunately , her mother died when she and her brother were very young. Her father was out of work and, worse luck, was seriously ill. She was studying at school, and her little brother Zheng Xiaogang was also studying at school like her. The two poor children had to work while studying so that they could afford the tuition and their father's medical costs. The father was becoming from bad to worse, and they had to pay more money. However,they were too young to 相似文献

Power optimization for pipelined analog-to-digital converter(ADC) was studied. Operational principle of pipelined ADC was discussed and noise voltage caused by two important thermal noise sources, sampling switch and amplifier, was quantitatively analyzed. Method used to minimize power and the values under simple model were presented. Power can be saved by making the sampling and feedback capacitors scale down in the pipeline. And the size of capacitors was limited by thermal noise in high resolution ADC. The equivalent circuits of the two important thermal noise sources were established. Thermal noise was optimally distributed among the pipeline stages, and the relationship between scaling factor and closed loop gain was obtained for minimum power dissipation. Typical closed loop gain was 2 or 4 in pipeline ADC, and the corresponding scaling factor was 1.217 and 1.317. These results can serve as useful guidelines for designers to minimize the ADC‘s power consumption. 相似文献

My grandfather was a teacher. He was the headteacher of a school for boys between the ages of thirteen and eighteen. I know that he was a kind and gentle man at heart, because when I was young(and he was old), he gave me presents, and sat me on his knee, and told me stories. But I believe the boys at his school were afraid of him. 相似文献

Quality function development (QFD) matrix was introduced as a tool to measure the quality management performance of contractors. Engineering quality, quality management system components, and their relationship were defined. An integrated engineering quality system was decomposed into seven factors and the quality management system was composed of eight factors. Importance weights of all factors and their relationship point were acquired by questionnaires and interviews. Then, QFD matrix was formulated and the calculating process was proposed. This model was verified on a case study. The result shows that it is useful for contractor in benchmarking themselves and invaluable for owners in the process of deciding contractor. 相似文献

The mathematical model of high-efficiency continuous billet casting was developed, incorporating the effective spraying water coefficient and the effective specific spraying water flowrate of secondary cooling. To realize uniform cooling in secondary cooling zones, the spraying cooling structure and the arrangement of nozzles were redesigned and optimized, and an additional spraying cooling zone was used. A new secondary cooling model of spraying water was built. It was found that the required spraying water flowrate of a cooling zone was related with the casting speed, the casting temperature, the compositions of liquid steel and the cooling water temperature of secondary cooling. The operation of the reformed caster proved that the spraying cooling structure and the new secondary cooling model were suitable, and the casting speed was greatly enhanced. The highest casting speed was (3.8 to 4.0) m/min for billet with a section of 150×150 mm2. The quality and the output of the billet were improved, and the economical benefit was heightened. 相似文献

A finite element model of one-arm planet carrier was built, and influence of structural parameters on strength and stiffness for one-arm planet carrier was analyzed. The stress and deformation of the round structure and the triangle structure for one-arm planet carrier were analyzed and compared. The finite element model of the same specifications arms planet carrier was established, and influence of the connecting slab thickness and input side plate thickness on strength and stiffness for arms planet carrier was analyzed. Strength, stiffness and mass for one-arm and arms planet carrier in the same specifications were analyzed and compared. 相似文献
