Abstract.
There are main crops, for example, wheat, corn, soybean, sweet potato, millet, sorghum, rice, cotton, peanuts, tobacco, hemp, vegetables, fruits, tea, medicinal materials, grasses, sericulture and etc, it is also the main production of grain, cotton, peanuts, vegetables and fruits, it’s output and quality are ranked the national best.
The development of modern agriculture must be equipped with agriculture on modern material conditions.
Besides, this paper discussed the relationship between the idea and only statistical data and the research material, individual results remains to be further research in practice.

Abstract.
Introduction Since the discovery by Iijima [1] and Bethune [2] in 1993, single-walled carbon nanotube (SWCNT) has been one of the most actively hot researches due to their unique physical, mechanical and electronic properties [3], SWCNTs are generally considered as having great potential for a broad spectrum of sciences from engineering, materials, chemistry, biology and medicine[4].

Keywords: micro direct methanol fuel cell; MEA; optimized anode; model
Abstract.
The major assumptions adopted in the model are as follows: (1) One-dimensional model, changes in x-axis is considered; (2) Due to the high thermal conductivities of the cell components, the cell temperature is assumed to be constant and uniform; (3) The pressure is uniform within each cell compartment; (4) Materials in each catalyst layer are homogeneous; (5) Due to the amount of water in the anode flow channels, the membrane is considered to be fully hydrated; (6) The voltage drop caused by contact resistance is ignored; (7) The overpotential caused by methanol crossover is directly proportional to the concentration of methanol at the cathode. 3.1 Anode overpotential Bulter-Volmer equation is employed to describe the relationship between current density and anode overpotential as following Eq. (1)
