They concluded that such upwellings might indeed account for the catastrophic fish deaths, but that they would not explain the deaths of insects, reptiles, birds and mammals, since these animals breathe air rather than relying on dissolved oxygen.
于是他们得出了结论,这些上升流可能正是造成鱼类灭亡灾的主要原因。但是这样并不能解释昆虫,爬行动物,鸟类和哺乳动物的死亡,因为这些动物靠空气呼吸,而不是靠溶解氧。

WASHINGTON - Scientists unearthed a skull of the most primitive four-legged creature in Earth's history, which should help them better understand the evolution of fish to advanced animals that walk on land. The 365 million-year-old fossil skull, shoulders and part of the pelvis of the water-dweller, Ventastega curonica, were found in Latvia, researchers report in a study published in Thursday's issue of the journal Nature. Even though Ventastega is likely an evolutionary dead-end, the finding sheds new details on the evolutionary transition from fish to tetrapods. Tetrapods are animals with four limbs and include such descendants as amphibians, birds and mammals.
华盛顿-科学家挖掘出一副地球历史上最原始的四足生物头骨,这个有利于帮组他们更好理解鱼类进化成为更先进的陆地行走生物,这个有着三亿六千五百万年年龄的头骨,肩膀和水生生物的一部分骨盆,Ventastega curonica,在Latvia被发现,研究者一篇研究报告发表在在星期三出版的自然杂志上,尽管Ventastega 可能是一个进化的死胡同,这个发现给出了从鱼类到四足动物进化变迁过程的新细节,四足动物是使用四肢的动物并且包括下属的比如两栖类动物,鸟类和哺乳类动物。

In mammals, the Notch signaling pathway is critical for embryonic development, as targeted disruption of Notch1 or its downstream transcription factor RBP-J in mice resulted in disorganization of somites and delayed closure of neurotube, which finally leads to early embryonic lethality.

Points out that the switching frequency、the input inductance and the output power all have great contribution to the input-current THD. When the output power goes up, the input current harmonic content keeps almost constant, thus the THD goes down.
指出开关频率、输入电感和输出功率对输入电流THD有显著影响,发现整流器输出功率增加时,输入电流谐波含量基本不变,从而输入电流THD减小。
