复活节，4天，为representation 写ppt，project不得不耽搁下来，aapratus 还是问题，没有technians 工作，不好开始，虽然很糟糕，as supervicer said : everything goes wrong. detector 坏了，明天去修，driving circuit not only cause sufficient nosiy , but also broken this afternoon due to careless muniplation . I don't know why I like to write in English , perhaps , it's easy to see , to type into the computer and to maintain some contuinty of writing since March. 很担忧，每次离开我的书，project 和GRE. 因为做的不好。 想保留一下my thinking , my motion and clear up myself at this moment . Yet I cannot find what I want to write down, nothing I think. To do is much better than just to think and write down .
