Perhaps you should try some spelling variations:
eu ansatzes » des ansatzes, neuen ansatzes, news ansatzes
yan liang » yang liang, wang liang, you liang
zhong tai » hong tan, hong hai, zhong zhi
qian yan » qian jun, qian yi
liang eu » liang sun, liang wei, liang zhu
dong di » dong sin
im j » tim j, m j, im _

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: qian yan liang eu ansatzes ((im j) OR (i j)) ((zhong tai) OR (dong di)) ;~.
• Adding a wildcard symbol may retrieve word variants: qian yan liang eu ansatzes ((im j) or (i j)) ((zhong tai) or (dong di)) ;*.
