值分布

Objective:To describe prevalences of behavioral problems inchildren aged 4~6 years,compare differences in distribution of behavioral problems among children in North Rural Area,South Rural Area,and South City Areaof China and provide references of Child Behavior Checklistforchildren aged 4~6 years in NRA,SRA,and SCA.

目的：描述我国4~6岁儿童行为问题现状，比较儿童行为问题地区分布差异并给出不同地区儿童行为问题检核表（Child Behavior Checklist，CBCL）内向性、外向性得分及CBCL总分的高危和临床界值的参考值。

Considering the design parameters of the BEPCⅡ, in the case of one cavity type being adopted, the thesis analyzes the RF performance of accelerating mode, the suppression of higher order modes , and the restriction caused by HOMs against beam current threshold.

结合BEPCⅡ的设计参数，论文对其中一种腔型在BEPCⅡ上使用时加速模式的微波性能、高次模的抑制效果以及高次模对储存流强阈值的限制等方面进行了分析，并在铝模型腔上测量了加铁氧体高次模抑制器前后，超导腔中各种谐振模式的有载品质因子及其频率的分布。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
