With modern machinery processing industry development, for the continuous
improvement of quality and accuracy of cutting, to improve the production
efficiency, reduce production cost, high intelligent and automatic cutting
function requirement also is increasing. The development of CNC Cutting machine
must adapt to the request of the development of modern mechanical processing
industry. Cutting machine flame cutting machine, plasma cutting machine, laser
cutting machine [1], water cut, etc. Laser cutting machine for the efficiency of
the fastest, the highest precision cutting, cutting thickness is generally
small. Plasma cutting machine cutting speed quickly, cutting surface has a
certain slope. Flame cutting machine for greater carbon steel in the thickness
of the material..
classification Cutting machine pictures Cutting machine pictures Cutting machine
to distinguish from cutting material, divided into metal cutting machine and
nonmetallic material cutting machine. Metal cutting machine flame cutting
machine, plasma cutting machine, laser cutting machine, water knife cutting
machine, etc.; Nonmetallic material cutting machine cutting machine mainly
tools. Cutting machine to distinguish from the control way, divided into CNC
cutting machine and manual cutting machine. CNC cutting machine Is to use
digital process driven machine movement, as the machine tool movement, random
matching of cutting tools for cutting objects. The mechanical and electrical
integration of cutter is called the CNC cutting machine. Laser cutting machine
for the efficiency of the fastest, the highest precision cutting, cutting
thickness is generally small. Plasma cutting machine cutting speed quickly,
cutting surface has a certain slope. Flame cutting machine for greater carbon
steel in the thickness of the material. Range of application Cutting machine
used with metal and nonmetal industries, in general, nonmetal industry points
more meticulous, as there is

This is an appraisal committee composed of experts from the Shanghai Institute of Plant Physiology and Ecology of the Chinese Academy of Sciences, and the results of the appraisal will be uploaded.
The expert group believes that the study uses heterologous crossbreeding combinations with obvious heterosis as a material and has integrated a number of effective high-yielding rice cultivation techniques. According to the physiological water requirement of paddy rice, the “spitting water†status of the rice plant tip For safety indicators, the implementation of the “water-based nursery, bacon, bain, ear, and wet-dry†16-character water-repellent layer water slurry management measures constitutes “high-yield dry cultivation method for single-season rice in irrigated paddy fieldsâ€. The yield of 600 kg per mu is similar to that of conventional irrigated rice, saving about 180 tons of water per mu, saving 15 yuan in electricity for irrigation and 15 kg in urea. The achievements are systematic, innovative and practical. They have made achievements in the combination of theoretical research and technical research and are worthy of demonstration and promotion.
The “Research on High-yield Dryland Production in Single-season Rice in Irrigated Rice Fields†undertaken by the China National Rice Research Institute uses “irrigated paddy fields with single-crop high-yield dry farming practices†to grow rice, which is 45% more water saving per acre than conventional ones.
