After molting three times, the zoea enter the mysis stage during which they begin to look more like adult shrimp and swim in a characteristic fashion with head and tail pointed downwards at right angles and occasionally performing a sudden retrograde jumping action. this is known as the inversion state, the fry being suspended upside - down in the upper middle region of the pond water. this is, therefore, also called the " inverted suspension phase "

直角彎曲而時作向後跳躍游動，又因成倒立狀態，懸浮於水中的中上層，又叫倒吊期，此期幼蟲對外界的環境因素，如水溫鹽分等變化，比前兩期來得更具適應力，主要餌料為豐年蝦brine shrimp的幼蟲，但其他大小略同的動物性浮游生物，如橈腳類copepoda輪蟲類rotifera均可。

As we know, inverse techniques make blade ' s profile well compatible with its surface velocity distribution, however, they give designers big challenges that the ideal velocity distribution is hard to obtained and sometimes the non - physical solution, such as double covering of flow field or unclosed profiles, would come out. the proposed design procedure in the paper has avoided the disadvantage mentioned above. in this paper, a quasi - irrotational equation is used to describe the flow in cascade instead of the generally used irrotational equation
眾所周知，一般的反問題和混合問題的最大特點，是在給定的壓力面和吸力面上的壓力分佈或速度分佈條件下，
直接得到葉片的幾何形狀，它可以使葉型型面與表面氣流參數有機結起來；其不足之處在於，對設計者而言，很難給定理想的葉片表面壓力分佈或速度分佈，並且有時會得到一個非物理解，如：得出的初始葉型可能會出現前緣、
尾緣不封閉的現象。
