在生活水平日益提高的今天，矮小症的发病率依旧不低。我国儿童矮小症的发病率大约为3%，仅上海市每月接诊的矮小症患儿达2500多名，值得引起父母们高度重视。 儿童身高有标准 人有高有矮，有胖有瘦。正是大家潜意识中有这种“真理”，致使父母们更容易忽视孩子们的身高状况。超过50%的父母不知道0～3岁就需要每两个月测量1次孩子的身高；30%的父母误认为只要营养跟上了，孩子的身高就能追赶上；75%的父母不
This paper extends the unifying theory for a posteriori error analysis of the nonconforming finite element methods to the second order elliptic eigenvalue probl
Semivarying coefficient models are frequently used in statistical models. In this paper, under the condition that the coefficient functions possess different de
By handling the travel cost function artfully, the authors formulate the transportation mixed network design problem (MNDP) as a mixed-integer, nonlinear bileve
The authors propose a V_(N,P) test statistic for testing finite-order serial correlation in a semiparametric varying coefficient partially linear errors-in-vari
在河南登封,芥菜也称大头菜,据说还与诸葛亮有关.诸葛亮路过嵩山时,有一次小染疾病上山采药,发现一种像萝卜却又不是萝卜的东西,拳头大小,上大、下小,咬一口一尝,不苦不涩,还
