组成代谢物

In terms of the contents and compositions of macromolecules in an Anabaena cell in the literature, the requirements of monomeric building blocks and precursor metabolites for cell synthesis were calculated, and an appropriate metabolic stoichiometry on cell biosynthesis was derived.

根据文献中鱼腥藻细胞大分子的含量和组成情况，计算了细胞合成所需要的小分子单体和前体代谢物的量，得到代谢意义上的细胞生物合成计量关系。

DESIGN: A 2-y longitudinal study to examine whether components of energy metabolism are predictors of body fat gain was conducted in 114 preadolescent African American and white children aged 9-11 y by measuring total daily energy expenditure on the basis of doubly labeled water, resting metabolic rate, the thermic effect of food, energy expended in physical actiity, and substrate oxidation after a meal.

设计：研究对象为114个青春期前的非裔美国小孩和白人小孩，年龄为9-11岁。通过用双标水法测定每日热能消耗总量、测定静息代谢率、食物的产热效应、体力活动能量消耗及餐后的底物氧化，进行一个2年的纵向调查，检测能量代谢的组成是否能够预测体内脂肪增加。

GC-MS or LC-MS is a kind of modern,fair chemical analytical technique,which combine higher separation ofChromatography with strong identification of Mass.It was applied in new drug research including concentration determination,impuritycheck,pharmacokinetic,anabolite analysis and so on.The paper reviews their application examples for recent years and shows itsdevelopment future.

气一质联用法和液一质联用法将色谱的高分离性能和质谱的高鉴别特点相结合，组成了较完美的现代分析技术，在新药研究的含量测定，有关物质检查、质量标准制定以及药物动力学研究的代谢物分析、药物及代谢物的体内浓度分布等试验中，成为有力的分析工具，文章综述了近年来色谱一质谱联用在以上领域的应用实例，展示了它的发展前景。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
