查询词典 induction factor

In this paper, a simulation study is made for both the vector-convertion model of a squirrel-cage induction motor and vector control system which takes the model as its control object. In the simulation model, many controllers are used and deeply studied, they are classical PID controller, simple fuzzy control, fuzzy controller with integration factor and fuzzy + PI dual mode controller. In the end of this thesis, fuzzy-neural controller application is stressed.

We aim to screen and identify the key potential trans-factors during hemoglobin switch. We firstly analyzed differential expression of mRNAs in erythroid induction cultures of CD34+ cells derived from normal umbilical cord blood, adult bone marrow, and bone marrow of a heterocellular hereditary persistence of fetal hemoglobin patient. We identified ZF (HCF-binding transcription factor, Zhangfei) and SH3GLB1(SH3-domain GRB2-like endophilin B1) that had differential expression in the above three cultures. Furthermore, we confirmed the different expression of the above two genes by quantitative real-time PCR.

为鉴别影响珠蛋白基因表达和开关的新的重要调节因子，我们首先分析了人脐带血、正常成人骨髓和异细胞型胎儿血红蛋白持续存在综合症患者骨髓细胞红系诱导培养物中基因表达的差异，发现ZF(HCF-binding transcription factor，Zhangfei)和SH3GLB1（SH3-domain GRB2-like endophilin B1）在这三种不同来源的红细胞内具有显著的表达差异，并通过实时定量PCR方法验证了差异的真实性。

Cells in the induction group were treated with L-DMEM consisting of 10% fetal calf serum and 10 μg/L basic fibroblast growth factor for 24 hours, then induced with L-DMEM consisting of 2% dimethyl sulphoxide and 200 μmol/L butyl hydroxy anisol for 1, 3 and 5 hours.

The experimental result shows that the main determinative factor is the temperature of the sea water for the growth after the transplantation; the optimal temperature for the growth of Zostera marina L. is 10~20℃; it is strongly salt-tolerant and it can grow at the salinity range of 20‰~48‰ normally; its rhizome is the optimal organ for culturing and the optimal hormone concentration for the calluses induction is 2mg/L or so.

实验结果表明，大叶藻移植后生长的主要制约因素是海水温度；大叶藻生长的最适温度是10～20℃；大叶藻对盐度的耐受性很强，它可以在盐度为20‰～48‰的范围内正常生长；地下茎是组织培养的最适材料；诱导愈伤组织的最适激素(2，4-D)浓度为2mg/L。
