Each object has its corresponding state, and each state corresponds to some corresponding behaviors. If an object has multiple states, there will be many behaviors. Then the judgment of these states and the behavior completed according to the states will lead to multiple conditional statements, and if a new state is added, the existing code needs to be changed. This kind of design obviously violates the principle of opening and closing, and the state mode is used to solve such problems.Intel's current processor development mode is "Tick-Tock", which also updates the microarchitecture (Tock) every two years and alternately upgrades the production process (Tick). Nehalem is a new architecture using 45nm process, while Westmere will be upgraded to 32nm in 2009 and Sandy Bridge in 2011. According to the latest intelligence, Intel will launch "IVY Bridge" in April 2012, which is Sandy Bridge's 22nm process upgrade. In 2013, "Haswell" was launched again, another new architecture based on 22nm process. Now it can be basically confirmed that Intel's next stop after 22nm will stay at 15nm. There is already a lot of evidence to prove this point. It is said that TSMC is the same. However, there are also statements that mention different nodes such as 16nm and 14nm, and IBM/AMD's plan is 16nm. It should be 11nm in the future, but Intel has also mentioned 10nm on different occasions. It seems that the distant future is still full of unknowns. In terms of code name, some people said that the 22nm Haswell in 2013 should be followed by Rockwell. According to the convention, the architecture will remain unchanged and the process will be upgraded.

It is really a lot of harvest and deep feeling. I have fully realized that only by combining theory with practice can I finish the work better. Before the activity should be carefully planned, try to think carefully, then the back will be smoother, after all, a good start is half the battle. In the process of activities, unplanned situations should be flexibly and reasonably adjusted. First of all, such investigation activities should gain the attention of local leaders and the understanding and support of the masses. Only in this way can we improve the work efficiency and better complete the task.新书为《终极圣师》，作者名：勇敢的灵魂，已发布，大家可以搜索一下，肯定不会让大家失望的。西域九层妖楼惊现数具尸体，古老的传说、诡异的诅咒、恐怖的尸变、骇人的血案。一股神秘力量不断支配着这个恐怖禁地。究竟是冤魂索命还是恶蛊作祟，众人几经生死，能否还世间一个真相......
