But he found eight-year-olds as tall as 13-year-olds, and boys of ten who weighed twice as much as others the same age. This distribution was viewed by the 19th-century Belgian mathematician Adolphe Quetelet as God's "curve of error", as if the tall and the short were deviations from a correctly proportioned "homme moyen", or average man.

但他的调查也显示：一些8岁儿童同13岁的一样高，一些10岁儿童比同龄重一倍。19世纪的比利时数学家Adolephe Quelet将此情况视为上帝的&错误曲线&——过高和过矮好比是对正常身高的偏离。

Methods: The sample consisted143 children which were in early permanent dentition of ClassⅡ,Division 1malocclusion .Pre-and post-treatment study models were assessed using PeerAssessment Rating index. According to the outcome of treatment, thesecases were classified into three types as "worse, no different","improved"and"greatly improved". The cephalometric analysis and Model Analysis werepreformed with pretreatment lateral cephalograms and study models for"improved"and "greatly improved"cases."T"–test was assessed to find out thesignificant difference between the extraction and nonextraction, and the resultsincluding age factor were analyzed by stepwise discriminant analysis.

To dissect single cells promising to culture from tissues, we researched the time of hydrolyzation of the tissues by tryposin, the result showed that the optimum time of hydrolyzation of the tissues was 5~10min when pretreated with 0.25% tryposin under the optimum conditions of pH8.0 at 37 C.We cultured four tissues: embryo at mediat-anaphase, head of high-age nymphae, spermary and ovary of adult.

组织块分离出来后，为了能获得单个的、有培养前景的细胞，本实验又研究了低浓度的胰蛋白酶在其最适温度和最适pH条件下，获得分离程度适宜的组织块的不同酶解时间，结果0.25％的胰蛋白酶在37℃、pH8.0的条件下酶解组织块的最适时间是5～10min。

In this last respect, he has much incommon with the other powerful figure of the age, the movie star. orby those, in Freud's words, who are "ruined by success."

The results show that strain 12.926 could make good use of Molasses as the carbon source;it could utilize KNO 3 as the nitrogen source effectively;48 h seed age was suitable;30% seed volume was required;The cell growth lipid formation and the production of palmitoleic acid were also influenced by initial pH markedly.

结果表明，12.926 酵母菌株能充分利用糖蜜作为碳源，能有效地利用硝酸钾作为氮源，种子种龄以48 h为适，接种量为30％，起始pH 值对菌体生长，油脂产生及棕榈油酸含量都有显著的影响。

Magnetic resonance imaging is the best radiological modality currently available for: a visualizing a spinal hematoma; b identifying its extension, anatomical location, and age; and c assessing the severity of spinal cord compression.5,21,22,28 In our patient and the one reported by Tseng and colleagues,32 MR imaging also clearly showed damage to the paravertebral soft tissues.

对于以下的损伤，MRI是最好的影像学方法：1、观察脊椎血肿；2、区分其涉及范围、解剖定位和年龄；3、评估脊索压迫程度。在本例以及Tseng和他的合作者们报导的病例中，MRI还清楚地显示了椎旁软组织的损伤。

The fresh chicken feces were obtained from different age 18 healthy chicken, and were not detectedchlortetracycline. The mixture standard solution of CTC and OTC was added in fresh chicken feces at the concentration of 0.5, 1.0 and 4.0ug/ml respectively. The chicken feces were divided to two groups,one were put in the incubator under photophobic condition; another were under the natural illumination.Samples were collected after 0, 0.5, 1, 2, 3, 5, 7, 9, 12 and 15 days, The concentration of chicken feceswas determined by HPLC. According to the theory of degradation kinetics, we fitted the changed trendof concentrations in chicken feces under different time and studied the degradation characteristics ofchlortetracycline in chicken feces.

选取不同日龄健康鸡18只，实验期新鲜鸡粪，，经检测不含四环素类药物，然后加入金霉素标准液，使得各样品中制得的相应药品的浓度为0.5ug／mL、1.0ug／mL、4.0ug／mL，分为两个实验组，第1组放入培养箱中避光黑暗条件下；第2组置于室外自然光下，定时取样，取样时间为0、0.5、1、2、3、5、7、9、12和15d，鸡粪中药物的浓度用本实验建立的高效液相色谱法测定，根据药物降解动力学原理，对鸡粪中药物的浓度随时间的变化趋势进行曲线拟合，研究金霉素在环境鸡粪中的降解动态规律。

Years of age do not eat honey, honey is a single sugar, the negative absorption, the same as glucose, do not eat, constipation can rule by other means, such as cooked apple to give him water to drink, or吃梨mud, pitaya can, my son is constipated the past two days, I cut half a dragon fruit for him to eat, because太凉, it can not be too much time to eat, so eat a quarter of a morning, afternoon, eat a quarter of of a stool as soon as they become soft, and give him water to drink, not to eat sweet baby food, because your baby's taste is very sensitive and may feel that the taste of the general adult non-sweet sweet baby food to said to be just, and not after the taste he will be getting heavier and heavier.
