The results showed that flood had obvious impacts on the maize density, maize greenery, ear lengthen and thick, and the yields, but not on the development process and one hundred grains weight.

In a matter of minutes, they have to estimate potential yield and quickly assess the quality of the beef, based on factors such as color, brightness, firmness and texture.

To solve the problem, this paper establishes a mechanical model of casing bend to explain the relative slipping and casing bend mechanism for some layer segments.
