Perhaps you should try some spelling variations:
eu ansatzes » des ansatzes, neuen ansatzes, news ansatzes
ansatzes im » ansatze im, ansatz im, ansatzes 2
yan liang » yang liang, wang liang, you liang
zhong tai » hong tan, hong hai, zhong zhi
liang eu » liang sun, liang wei, liang zhu
nan yan » nan ya, wang yan, qian yan
dong di » dong sin
im j » tim j, i j, m j

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: nan yan liang eu ansatzes im j ((zhong tai) OR (dong di)) ;~.
• Adding a wildcard symbol may retrieve word variants: nan yan liang eu ansatzes im j ((zhong tai) or (dong di)) ;*.
