查询词典 higher level

The minimum fluidization velocity has a minimum value when the frequency of sound waves is 120Hz and it will decrease as the sound pressure level increases. The degree of sound attenuation will increase while bed material is higher and the fluidization quality of fine particles will become poor and the minimum fluidization velocity will increase. Compared with TiO2, the SiO2 fine particles have a better quality of fluidization at the same fluidized conditions.The cluster/subcluster model and oscillators model are used to describe the fluidization characteristics of fine particles in a sound-assisted fluidized bed. The theoretical calculations show that the minimum fluidization velocity umf is decreased with the SPL increased at the same frequency of sound and the quality of fluidization is better.

论文还系统的考察了声压和频率对纳米SiO2和TiO2颗粒流化特性的影响，结果表明：在频率一定的情况下，声压越高，流化床中形成的聚团尺寸越小，最小流化速度越低，流化质量越好；当声压低于120dB时，声场对超细颗粒流化特性的影响减小，当声压大于130dB时，则能显著改善流化效果，使流化床内的颗粒聚团明显减小，最小流化速度明显降低，粉体带出减小；声压一定，频率为120Hz左右时，最小流化速度最低，此时流化床中形成的聚团尺寸最小，流化效果最好；超细颗粒达到较好的流化状态存在一个最佳频率范围，随着声压增高，这个频率范围将增大。

objective to study gastrodia elata blume to effect tau protein,sod,mda expression in gyrus hippocampi and cerebral cortex of experimental mice.methods to inject okadaic acid to mice ventriculus lateralis and to measure tau protein level,sod activity and lipid superoxide mda content of sod control group,oa injection group,oa and gastiodia elata injection solution group.results tau protein of experimental group(p＜0.05/p＞0.05),sod was lower than model group(p＜0.001) and was higher than control group(p＜0.05).conclusion gastrodia elata blume can increase sod activity and reduce tau protein expression and superoxide lipid forming in brain tissue of experimental dementia mice caused by oa.it can prevent and treat ad.

目的 观察天麻对痴呆模型大鼠海马、皮质神经元微管相关蛋白、超氧化物歧化酶和脂质过氧化物丙二醛表达的影响，探讨其治疗阿尔茨海默病(alzheimer disease，ad)的作用机制。方法用冈田酸(okadaic acid，oa)注射大鼠侧脑室造模，测定模型组、实验组、对照组海马和皮质tau蛋白、sod、mda的含量。结果实验组tau蛋白低于模型组(p＜0.001)，高于对照组(p＜0.05)；sod高于模型组(p＜0.001)和对照组(p＜0.05)；mda低于模型组(p＜0.001)，高于对照组(p＜0.05)。结论天麻可增强oa致实验性痴呆大鼠脑组织sod活性，降低mda蓄积和tau蛋白生成，具有防治阿尔茨海默病的作用。
