In Ada 95 an abstract type could only have one immediate ancestor, but in Ada 2005 it is possible to derive a new type from multiple interfaces or tagged types.
In addition, the reverse engineering of Ada code is improved so that it USES Ada designs better.
另外，Ada代码的逆向工程也得到了改善，这样它就可以更好的使用Ada设计了。

Analysis shows that different ADA isomerides have different desulfurization activity and solubility, and the desulfurizer with same ADA concentration have quite different desulfurization result.
