高速电动机目前被广泛用于汽车自主驾驶系统。由于高速电动机采用小质量设计,因此为了使转速和输出扭矩达到目标值,通常将渐开线齿轮组和它配套使用。然而,传统的渐开线齿轮在工作中噪声较大,因此一种新型的具有不规则轮齿设计的低音调(Low⁃Tone)齿轮被开发,以减少齿轮传动装置的噪声。通过优化算法,开发设计了一种Low⁃Tone齿轮,并应用于一个驱动电动车尾门启闭的电动推杆系统。之后在该系统运行期间,对使用Low⁃Tone齿轮和使用传统齿轮所产生的声压进行测量对比。结果表明,Low⁃Tone齿轮对于噪声有较好的抑制作用,其优势特别体现在音调特性方面。

Objective:To investigate the antimalarial activity of ethanol extract of Aspilin africana (***) ***:The ethanol extract of *** leaf(100-400 mg/kg) was screened for blood schizonticidal effect against chloroquine-sensitive Plasmodium berghei(P. berghei) in mice both in early and established models of antimalarial ***:The leaf extract exhibited significant(P<0.05) antiplasmodial activity in 4-day early infection and in established infection tests with a considerable mean survival time comparable to that of standard drug,chloroquine(10 mg/kg).Conclusions:The findings show thai ethanol extract of *** leaf possesses potent antiplasmodial activity which justify the use in ethnomedicine and can be developed in malaria therapy.
