Perhaps you should try some spelling variations:
ansatzes im » ansatz im, ansatzes 2, ansatzes 3
ansatze im » ansatz im, ansatze zum, ansatze zu
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

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) OR (ansatze im)) j ((zhong tai) OR (dong di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan yan liang eu ((ansatzes im) OR (ansatze im)) j ((zhong tai) or (dong di)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan yan liang eu ((ansatzes im) OR (ansatze im)) j ((zhong tai) or (dong di)) ;*.
