In order to reasonably depict four basic problems with friction, one Coulomb friction new form in first Kirchhoff stress is proposed to deal with finite deformation problems, other Coulomb friction form in incremental mode to elastoplastic flow theory; Hilbert function spaces concerning elastoplastical problems with friction are established, so it makes all operations and calculations in the treatise standardized within the scope of reasonably topologic structure; In view of functional extremum, the equivalence between generalized variational inequalities principles in elastoplasticity with friction and corresponding basic problems are testified by inducing Lagrangian multipliers, so it provides a rationally theoretical basis for numerical methods in elastoplasticity with friction; From the viewpoint of variational inequality, the theory of generalized variational inequalities in elasticity and elastoplasticity with frictional constraint is studied, and the uniqueness and existence of the solution of FEM is proofed under the proposed conditions of stress compatibility, and them FEM approximation and a discrete solution are discussed; Based on the principles of generalized variational inequalities in elastoplasticity with friction, direct generalized variational inequalities methods is pretended, which is a natural generalization and development of direct variational methods; Using generalized variational inequalities methods, some examples in metal forming including plane deformation, upset and extrusion are analyzed and the results prove that all the theories and methods in the paper are right, feasible, accurate and advanced.

Like learning, a failure does not mean anything, it might tell you: Maybe you should change our thinking and concepts, to be upbeat about it; maybe you should change the learning method, we should rationally arrange time; maybe you should correctly deal with problems, need to raise into the habit of hard thinking; perhaps to remind you that school is gone God, absent-minded; maybe you just 1:00 to inadvertence, not really did not grasp the ...... In any case, you should not be too care about a failure and negative pessimistic, we should of failure as a driving force in order to defeat as a lesson, let failure be your stepping stone, to be more diligent and hard to let failure to become a successful guide your next step.

就像学习，一次失败并不代表什么，它可能在告诉你：或许你该转变思想观念，要积极乐观一点；或许你应该改变学习方法，要合理安排时间；或许你应正确对待难题，要养成勤于思考的习惯；或许在提醒你，上课是否走了神，心不在焉；或许你只是一时粗心大意，并不是真正没掌握……不管怎样，你都不要太在乎一次失败而消极悲观，要化失败为动力，以失败为前车之鉴，让失败成为你的垫脚石，要更加勤奋刻苦，要让失败成为引领你下一次成功的阶梯。

The results shown that there will be great potential capacity to increase grain output in production, and the grain yield are positive related with the amount of fertilizer markedly as a whole, but there have been imbalance and inconsequence in using of fertilizer. It is essentially important to improve fertilizer use efficiency for save resources as well as increase yield. To increase grain output should to arrange fertilizer by planning as a whole rationally rather than to increase its amount.

结果表明，藁城市粮食生产还有很大的增产潜力，总体上粮食产量与化肥的投入仍然呈显著正相关关系，但是，目前实际生产中化肥施用量存在极其严重的不平衡和不合理现象，所以增施化肥已不再是增产的主要措施，而合理统筹、提高化肥的利用率至关重要，是节能增效的重要措施。
