【正文】 der cable shielded twisted pair, and for other Japanese Yaskawa servo system product is 6cell absolute encoder, incremental is 4 Motor Installation Notes 1, the servo motor oil and water conservation A: servo motor can be used in water or oil droplets will be affected by the invasion of the place, but it is not fully waterproof or , the servo motor should not be placed or used in water or oil intrusion in the : If the servo motor connected to a reduction gear, use the servo motor fuel should be sealed to prevent the reduction gear oil into the servo motor C: servo motor cable not immersed in oil or , servo motor cable to reduce stress → A: Make sure the cable is not due to external bending moment, or by their own weight or vertical load, especially in the cable outlet or : In the case of the servo motor moves, should the cable(that is configured with the motor Flanagan)is firmly fixed to a stationary part of the(relative motor), and should be installed in the cable with a bearing in the attached cables to extendit, so the bending stress can be : cable bend radius be as large as , the servo motor allows the shaft load A: make sure when you add in the installation and operation of the servo motor shaft in radial and axial load control within the specified value for each : When installing a rigid coupling to be cautious, especially over the curved shaft and bearing load may cause damage or wear C: best to use a flexible coupling, so that the radial load below the allowable value,This material is designed for high mechanical strength of the servo motor : axial load on the permit, please refer to the “permissible axle load table”(Manual).4, the servo motor is installed Note A: In the install / remove ponents to the servo motor shaft coupling, do not directly tap with a hammer shaft.(Direct beat hammer shaft, the other side of the servo motor shaft encoder to be knocked bad)B: strive to align the shaft to the best state(on a bad vibration or bearing damage may result.) servo motor characteristicsFirst, the DC brushless motor features: small moment of inertia, low starting voltage, load current is small。 contact change to the system, greatly improving the motor speed, maximum speed up to 100 000rpm。 servo motor servo control in the implementation, the encoder can also be achieved without the speed, position, torque control。 is no brush wear, in addition to high speed, but also has a long life, low noise, electromagnetic interference and other characteristics。Second, the DC brush servo motor characteristics: volume is small, the fast response quick, overloading capacity, wide speed range。 torque, and fluctuations in small, smooth。3..low noise, high efficiency。 encoder feedback(optional)constitute the advantages of the DC servo。Use: DC servo motor can be used in a spark machine, robot, precise also configure the 2500P / R analysis of the degree of high standard encoder and tachometer, with gear box plus more, so that the accuracy of machinery and equipment to bring reliable and high is good, unit weight and volume, the output power of the highest, more than AC motors, and much higher than the stepper structure of the torque ripple small.第二篇：1300外文文獻(xiàn)翻譯Agricultural Land and Regulation in the Transition Economy of Russia Ekaterina Gnedenko1 amp。 Michael Kazmin2 Published online: 7 July 2015 International Atlantic Economic Society 2015 JEL Classification This research note explores the link between farmland conversion and existing land regulation in conclude that land regulation is lagging the new market trends in the transition economy of market forces continue to penetrate the economy, apparent managerial and statutory problems with regard to local landuse planning and regulation preclude more effective use of to the need for attracting investment in agriculture, the Russian Ministry of Science and Education provided funds for our research project that involves primary data collection and econometric analysis of the interdependencies between governmental policies and farmland unique dataset contains socioeconomic, demographic and spatial geographic 2010 data for 39 municipal districts in the Moscow metropolitan econometric analysis of this data set is used to explore the relationship among farmland quantity, its assessed value, the share of privatized farmland, farmland tax,and landuse zoning in the simultaneous equations the Russian market for real estate has developed quickly, the market for agricultural land is still deals are limited, partly because of the lingering uncertainty about farmland property stateowned farmland is still Moscow regional data suggest a strong positive relationship between the fraction of privatized farmland and farmland acreage, although the fraction of individually and collectively privatized farmland is only 57 %.The direct sale of farmland to foreigners is prohibited decreasing potential foreign investment as a result, the area occupied by agricultural lands has been steadily decreasing and deteriorating in the period 1990 to 2005, tillable lands in Russia have shrunk by million hectares( % of tillable lands).Lacking experience and adequate knowledge, local governments are stuck with the land conservation policies available to the former particular, in an attempt to contain the loss of prime farmland, the regulators retain old landuse zoning laws prohibiting the change of land , strong development pressures and widespread corruption often annihilate the desirable effect of results of our econometric analysis indicate that the proximity to Moscow city and population growth both have a significant negative effect on the amount of farmland, even in the strictlyzonedfor agriculture districts, suggesting strong urban pressure in the capital region of estimated elasticity of farmland acreage with respect to population growth is ? corrupt practice of illegal changes in land status is reflected in the fact that the lands still classified as farmland in the F
