活化

It is a cementitious material in potential and can be used in cement and concrete area after been activated.

采用适当的活化方式激发其活性，可将钢渣应用于水泥、混凝土领域。

However, it is not known how orthodontic force influences the function of cementoblast and what is the relationship between the function change of cementoblast with root resorption. So we studied the effect of mechanical stimuli on root resoption by examining the expression OPG and RANKL and exploring the related signal transduction pathway in cementoblast. Methods: Cementoblasts OCCM30 were cultured in DMEM with 10% FBS for 48 hours and starved in DMEM with no FBS for 24 hours, then subjected to mechanical strain by four-point bending system with tension and compression stress at 2000μstrain at 0.5Hz frequency. The flow cytometry was used to examine the cell cycle and proliferation activity after 3h, 6h, 12h, 24h loading respectively. OPG and RANKL mRNA were analysed with real time quantitive RT-PCR after the same loading period as FCM.

本课题利用四点弯曲力学加载系统，采用流式细胞术、实时荧光定量PCR、Western免疫印迹等方法，研究体外培养的成牙骨质细胞株OCCM-30在不同力学环境中增殖活性的变化，以及其表达骨保护素和破骨细胞分化因子的mRNA的变化，探讨应力刺激对成牙骨质细胞表达破骨细胞分化调控蛋白的影响，并通过对应力刺激下成牙骨质细胞分裂原活化蛋白激酶家族中的ERK1/2、P38MAPK活性的变化及其与OPG、RANKL基因表达变化关系的研究，对力学刺激调节破骨细胞分化调控蛋白的相关上游信号转导通路进行初步探讨。

As the results show: The two submerged macrophytes can also adapt to the polluted water. Under the condition of high nitrogen in the sediment, they can remove the nitrogen effectively, and the removal effect of Ceratophyllum demersum L.is better than Hydrilla verticillata Royle. Hydrilla verticillata Royle activates the TP in the sediment more effectively than Ceratophyllum demersum L.. The submerged macrophytes can intensify the removal effect of turbidity. But the CODMn removal effect of submerged macrophytes are not obvious.

结果表明：生长晚期的黑藻和金鱼藻仍可适应污染河水；在底泥含氮量较高的情况下，生长晚期的沉水植物对氮素具有明显的去除效果，且金鱼藻的脱氮能力高于黑藻；黑藻对底泥中TP的活化能力高于金鱼藻；沉水植物可以强化浊度的净化效果；沉水植物生长晚期对CODMn的去除效果不高。

GC-MS is used to determine content of free TDI, reaction kinetics is analysed by chlorhydric acid/n-dibutyl amine titration -NCO method and DSC, so the system activation energy is calculated.

采用气相色谱-质谱法测定其游离TDI含量，用盐酸-正二丁胺滴定-NCO法和DSC法相结合，分析反应动力学规律，计算体系表观活化能。

The experiments showed that polypeptides were formed by self-assembly of N, O- bis amino acids with the assistance of o-phenylene phosphoro- chloridate. Three steps were involved in the self organization reactions, i.

侧链无官能团的N，O-二-α-氨基酸在O，O-亚苯基磷酰氯辅助下能自组装得到系列2～n聚寡肽，其自组装成肽过程大致分为三步：氨基酸的活化、肽链的延长和链反应终止。

In this thesis, four methoxypolyethylene glycols (MPEG, molecular masses 350, 750, 2000 and 5000 Da), each activated by nitrophenyl chloroformate, were used to modify trypsin.
