2012年,Hyundai汽车集团推出1款采用连续可变气门升程(CVVL)机构的发动机。该发动机是专为中型轿车设计的直列4缸2.0L汽油机,具有燃油耗低、性能高及响应快的特点。CVVL机构是一种6连杆机构,具有结构紧凑和坚固耐用的优点。相比传统机型,CVVL发动机的燃油经济性提高7.7%,最大功率提升4.2%。生产CVVL发动机最具挑战性的问题是发动机各气缸气门升程的偏差。为了调整气门升程的偏差,设计了气门顶垫片和调节螺钉。通过测量气门顶部高度和凸轮支架总成的蹄形升程,选择垫片厚度。调节螺钉是调整气门升程偏差的辅助装置。开发了适用于CVVL发动机工厂装配线的气门升程偏差诊断系统,并用测试装置直接测量气门升程。该诊断系统位于配气机构装配台后,可以实时监测气门升程的变化,并给出装配系统的快速反馈。

In semiconductor manufacturing process, probe station that is testing equipment is important. Inspection step is for detecting defects on semiconductor before the packaging. Probe card is a part of probe station and contains probe tip that contacts to semiconductor. Through probe tip, it can inspect defects of semiconductor. In this paper, optimization method is used with response surface analysis to design MEMS type probe tip. And fabricating probe tip uses maskless lithography, electro-plating and lapping process.

Litter production, decomposition and nutrient release dynam-ics of Ochlandra setigera, a rare endemic bamboo species of Nilgiri biosphere were studied during 2011-2012 using the standard litter bag technique. Annual litter production was 1.981 t？ha-1 and was continuous throughout the year with monthly variations. Litterfall followed a tri-phasic pattern with two major peaks in November, 2011 and January, 2012 and a minor peak in July, 2011. The rate of decomposition in O. setigera was a good fit to the exponential decay model of Olson （1963）. Litter quality and climatic conditions of the study site （maximum tem-perature, monthly rainfall and relative humidity） influenced the rate of decomposition. Nutrient release from the decomposing litter mass was in rank order N=Mg＆gt;k=Ca＆gt;P. Nutrient release from litter was con-tinuous and it was in synchrony with growth of new culms. Study of litter dynamics is needed before introduction of a bamboo species into degraded or marginal lands or Agroforestry systems.
