这种情况下 名词前加形容词不需要冠词吗

a series of new inventions ， the development of new technology 问 new inventions ，new technology 为什么不需要冠词 还是可加可不加呢 谢谢~~

1 a series of new inventions -----不要the，因为是泛指
a series of THE new inventions of this company ------这里要the,因为被this company限定了

2 the development of new technology-----不要the，因为是泛指
the development of THE new technology based on Mr. Wang's idea about the moon------这里要the,因为被based on Mr. Wang's idea about the moon特定了

它们前边已经有了“定”它们的“a series of ”和“ the development of ”

这个要看看这些词在句子中做什么成分了
