Compared with the traditional saving way by paper, it can not only save the precious data of soil census effectively by computer technology to supply detailed data for the various agricultural planning and forecasting, but also can make complex space analysis to all kinds of soil data to supply reliable materials for the various agricultural planning and deciding, which is good for the using and sharing of the soil data and promote the development of "digital agriculture".

A nation can purchase the necessary materials from other nation and the condition that primary elements are not limited in Von Neumann is adaptive.
If a nation can firstly get the quantity and scale of the national economic system in the next year and afterwards purchase the required material, the production of a nation will decrease the storage and production cost.

Fig. 2.The finite element model of the girder Fig. 3.The virtual prototype of beam-carried crane with flexible body Dynamic Analysis Results During the application of Beam-carried cranes in engineering construction, the load for the girder consist of both impulsive load and periodical alternating load for wiggling movement of heavy material.
Where is the mass of the lifted material, here ; is the acceleration of gravity, here ; is the coefficients, here ; step(*) define step function response from 0 to 1 within 0.2s.The simulation result of the displacement for the girder’s centroid with step load was shown in Figure 4.
And they can be derived by formula listed as[5]: , , So the transfer function of the girder’s vibration system can be got as: (3) Sine Response Simulation.According to lifting height in design, the frequency span of lifted material is 0.5~2Hz.
