在冲压过程中,机械运动贯穿始终.各种冲压工艺的实现都有其基本运动机理,这种成形运动是与模具密切相关的,各种模具的结构设计和力学设计最终都是为了满足其能够实现特定运动的要求.设计的模具能否严格完成实现冲压工艺所需的运动,直接影响到冲压件的品质,所以在模具设计中应对机械运动进行控制.同时为了达到产品形状尺寸的要求,不能拘泥或局限于各种工艺基本运动模式中,而应不断发展和创新,在模具设计中灵活运用机械运动. 相似文献

A series of studies extended psychometric research on the Adjustment Scales for Preschool Intervention (ASPI). The ASPI is a multidimensional measure of preschool emotional and behavioral adjustment for use within formal early childhood educational programs. These studies used a multiple method, multisource approach to provide additional evidence for the reliability and validity of the ASPI. Findings documented inter‐rater reliability of the ASPI across key informants within early childhood educational programs—teachers and teacher assistants. Findings supported concurrent validity of the ASPI with direct observations of preschool classroom adjustment problems and the developmentally salient constructs of temperament and emotion regulation. Implications for policy, practice, and future research are discussed. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 725–736, 2004. 相似文献

棉花施用惠满丰有机复混肥增产效应研究 总被引:2,自引:0,他引:2
在当季不施肥,皮棉产量50kg/667m~2以上的生产条件下,棉花施用惠满丰有机复混肥30-70kg/667m~2,伏前桃增加1-1.5个,株高增加9.9-17.1cm,茎粗增加0.2-0.8mm,有效果枝增加约1.3个,单株成铃数增多1.1-3.1个,单铃重约增加0.4-0.5g,霜前花率提高3-9个百分点,衣分、子指也有所提高,比对照增产皮棉14.1-31.8kg/667m~2,增幅27.4%-61.1%(平均45%)。在等养分量情况下,惠满丰有机复混肥肥效优于化肥。惠满丰有机复混肥的经济合理施肥量为70kg/667m~2。 相似文献

Research Findings: Children learn most of their vocabulary incidentally, by hearing words used in their environment. This study explored which kinds of presentations of words, without any direct instruction, yielded greater depth of target word knowledge. Changes in 56 kindergartners’ depth of knowledge for each of 23 novel target words (N = 1,288) based on presentation in 1 of 3 conditions (read-aloud, teacher conversation, or both read-aloud and conversation) were explored and compared to control words that were never presented. A 2-level, cross-classification analysis modeled the postintervention score for each word for each child. Children’s word meaning knowledge improved most when words were presented via combined conversations and read-alouds. Vocabulary gains for words presented via conversations differed across classrooms. Practice or Policy: Both teacher conversations and read-aloud presentations of target vocabulary should be used together. Professional development for teachers’ effective vocabulary conversations may be needed. 相似文献

The current study deals with the development of system thinking skills at the junior high school level. The sample population included about 50 eighth‐grade students from two different classes of an urban Israeli junior high school who studied an earth systems‐based curriculum that focused on the hydro cycle. The study addressed the following research questions: (a) Could the students deal with complex systems?; (b) What has influenced the students' ability to deal with system perception?; and (c) What are the relationship among the cognitive components of system thinking? The research combined qualitative and quantitative methods and involved various research tools, which were implemented in order to collect the data concerning the students' knowledge and understanding before, during, and following the learning process. The findings indicated that the development of system thinking in the context of the earth systems consists of several sequential stages arranged in a hierarchical structure. The cognitive skills that are developed in each stage serve as the basis for the development of the next higher‐order thinking skills. The research showed that in spite of the minimal initial system thinking abilities of the students most of them made some meaningful progress in their system thinking skills, and a third of them reached the highest level of system thinking in the context of the hydro cycle. Two main factors were found to be the source of the differential progress of the students: (a) the students' individual cognitive abilities, and (b) their level of involvement in the knowledge integration activities during their inquiry‐based learning both indoors and outdoors. © 2005 Wiley Periodicals, Inc. 相似文献
