Conclusions (1) during the cold wave hits. concrete structure will have a greater tensile stress .In order to prevent cracks, attention should be paid during the cold wave on the surface of the insulation measures, and before the arrival of the cold, appropriate materials for surface insulation should be selected according to cold wave type and magnitude

College of Agricultural Engineering, Henan University of Science and Technology, Luoyang China, 471003 ) Keywords：Corncob; Elastic Modulus; Poisson's ratio;Strain Gauge Abstract:The Elastic Modulus and Poisson's ratio of corncob were Measured by electrical method.The sensor was electric-resistance strain gauge.When the corncob was applied by force,the strain of corncob transformed into resistance changing of the sensor.Then,measure the resistance by SINOCERA YE253 programmable static strain gauge and transmit the resistance into the strain.It was found that the Elastic Modulus of corncob under the moisture content of 10.5% is 1.208×109 Pa and the Poisson's ratio is 0.33.
Introduction The corncob is easy to be broken during the process of threshing.The broken corncob is not good for the separation and cleaning of kernels.So,it is a meaningful thing to study the force nature of corncob for threshing corn ear.The material of corncob is similar to the material of wood.Both of them are heterogeneous material.As for the regular pattern of corncob and wood,the test pieces could be regarded as elastomer when the test pieces were forced by small stress.Elastic Modulus and Poisson's ratio are important elastic constants of the test pieces.There are many methods to measure the elastic constants.For example,stretch meter method,laser speckle interferometry,ultrasonic method, electrical method and so on.Slikker started to measure the elastic constants of wood by electrical method in the 1960s[1].In China,Li Weizhe[2],Gong Meng[3],Shao Zhouping and Zhu Shan[4] had measured the elastic constants of northeast China ash wood, masson pine,fir.I have not seen a paper about
