Conclusion: Ploughing therapy helped to improve local microcirculation in the wounds and to promote removal of necrotic t.

目的 :探讨耕耘疗法在中小面积深度烧伤创面治疗中的疗效。

The motivation, basic concepts and research methods of data farming were introduced.

数据耕耘是一种有效的探索分析战争复杂系统的方法。

In foreign countries, the cultivator work for long-term applications in agriculture production, but the use of it is little in China.

在国外,耕耘机被长期应用于农业生产中,在我国的使用却很少。

Based on the experimental data,this paper analyzed influence which axle rotational speed,cultivator advance speed and cultivation depth of self-propelling cultivator worked on unit cubage power consumption.

在试验数据的基础上,分析了自走式耕耘机刀辊转速、机器前进速度和耕深对耕耘机单位体积功耗的影响,通过回归分析,建立耕耘机单位体积功耗与各运动参数之间的数学模型,并以此为优化设计的目标函数,通过计算机优化程序,得到在一定约束条件下耕耘机的最优刀辊转速和机器前进速度,进一步计算得到最优速比系数的取值范围,为自走式耕耘机的设计提供一定的理论依据。

Whirling blade radius is an elementary parameter in the cultivator design.

刀辊半径是耕耘机设计中的一个基本的设计参数。

To improve the test method and appraise the function of cultivator,a system containing machines,electrical equipments and instruments is designed.
