Sequence analysis of the second internal transcription spacer of ribosomal DNA from Anopheles dirus and Anopheles stephensi

It is not so much that the spaceplane would be especially efficient, but rather that the shuttles are especially inefficient, and that NASA has so far succeeded in playing down this fact.

这里并不是说太空飞机特别有效，相反地是航天飞机效用非常低，而国家航空航天局至今一直贬低这一事实。
