查询词典 curve of growth

At growth period of Moso bamboo, because the root has not grown completely and has little influence on rhizosphere soil, so the score was the highest. The score of rhizosphere soil decreases as the growth and root gradual development of Moso bamboo. The rhizosphere soil quality increased at later stage of Moso bamboo because of gradually weakened growth and the increased litter and microorganism activity.3.The demands for nutrients of Moso bamboo at different growth periods were different. It was different in the demand for nutrients of Moso bamboo at different growth period.

成竹期由于根系未完全形成，对其根际土壤的影响较小，因而成竹期得分最高，随着毛竹生长，根系渐渐发达，对其根际土壤的影响日渐扩大，造成根际土壤得分渐低，后期毛竹生长逐渐减弱，对其根际土壤的影响也随之减少，加上林中凋落物的增加和微生物活动增强，其根际土壤的质量有所增加。3、不同生长阶段毛竹对营养元素的需求有所不同。

Show model combines growth model, math model and VR technologies to design the proper object structure of each organ of virtual plant. First of all,research background, research content of virtual plant area and Virtual Reality technology are introduced. The concept of VR and research content of virtual plant are defined. Secondly, we analyze math model of virtual plant, including Bezier curve, NURBS curved surface, fractal system, L-system and Catenary curve. Thirdly, we give show model of virtual plant in detail. Finally, the design of the platform and growth model on XML script is introduced , and how to show the virtual plant in the platfrom is discussed too.

Methods: Rat MSCs were isolated with percoll and nonadherent cells were discarded 48 hours later. The shape was observed and CD34, CD44, CD45, CD166 were detected with Flow cytometry analysis. The growth curve of MSCs in different concentration of fetal bovine serum was observed by MTT colorimetry. The growth curve and attachment efficiency of MSCs of passage 1 (P1), P3, P5 and P10 were also observed.

There were 70 strains isolated from each of the MRS and VJ at the different stage of the processing of dried beef. Staphylococcus warneri, Staphylococcus sciuri, Staphylococcus auricularis, Bacillus subtilis, Staphylococcus xylosus, Staphylococcus saprophyticus, Lactobacillus plantarum and Pediococcus pentosaceus were 8 predominate bacteria. The growth curve of predominate bacteria was studied. The result showed that growth of Pediococcus pentosaceus was faster than that of Lactobacillus plantarum; the growth of Staphylococcus sciuri is fastest and Staphylococcus auricularis was slowest.
