The cell suppression ratio and surviving ratio were detected respectively under conditions of simple hypoxia, or 5mmol/L glucose complicated with hypoxia. The mRNA levels of key enzymes that are involved in regulating glyco-metabolism were detected, including the mRNA levels of pyruvate-kinase, hexokinase, succinic dehydrogenase and isocitric dehydrogenase, and the activity of lactate dehydrognase.

以SMMC-7721人肝癌细胞和L02正常肝细胞作为研究对象，分别在单纯缺氧及加葡萄糖缺氧条件下，观察细胞生长，并检测糖代谢关键酶：丙酮酸激酶(pyruvate-kinase， PK)、己糖激酶(hexokinase， HK)、琥珀酸脱氢酶(succinic dehydrogenase， SDH)、异柠檬酸脱氢酶(isocitric dehydrogenase， IDH) mRNA表达水平和乳酸脱氢酶(lactate dehydrogenase， LDH)活性。

A method combining HPLC, a post-column derivation device and a fluorescent detector was used to determine residues of ten carbamate pesticides （aldicarb sulfoxide, aldicarb sulfone, oxamyl, methomyl, 3-hydroxy carbofuran, aldicarb, propaxur, carbofuran, carbaryl and methiocarb） in 68 vegetable and 32 soil samples under four different cultivation systems （traditional kailyard, open field vegetable base, green house and paddy） were collected from a certain city in South Jiangsu.

本研究采用高效液相色谱-柱后衍生-荧光检测法分析了苏南某市4种不同种植方式下（传统菜地、露天蔬菜基地、大棚蔬菜基地和水稻田）68个蔬菜样品和32个土壤样品中10种N-甲基氨基甲酸酯类农药（涕灭威、涕灭威砜、涕灭威亚砜、杀线威、灭多威、残杀威、克百威、3-羟基克百威、甲萘威和灭虫威）的残留量，结果表明在蔬菜中检出的氨基甲酸酯农药残留水平多处于0.2～23μgkg^-1，土壤中为0.1～10μgkg^-1；土壤中3-羟基克百威和灭虫威全部检出，其最高检测浓度分别为10μgkg^-1和1.64μgkg^-1，其他农药仅有少数检出。

The sub-problem optimal way is used to optimize the mutual insert multi-span greenhouse and the optimal result is disposed using iterated algorithm. Through repetitious iterative disposing the optimal result of three kinds of loads to the mutual insert multi-span greenhouse, it is acquired that the arch pipe's diameter is 32mm, the knighthead's diameter 20mm, the mutual distance 60cm and the gradient side pole's horizontal projection distance is 50cm.

采用零阶优化方法对互插式塑料温室的优化计算结果进行多次迭代处理，得到3种工况下的优化结果：拱杆直径为32mm；支撑杆直径为20mm；互插间距为60cm；倾斜侧杆的水平投影为50cm。

Generally, the increase of central city population is much faster and more lapsable than which of the region. The purpose of this paper is to establish a model of the population relationship between the region and its central...

因此，笔者试图构建中心城市人口与区域人口数量关系模型，以预测区域人口去推导中心城市人口，并在此基础上进一步研究在区域人口和城镇化水平趋于稳定状态下的稳定态城市规模。
