Cries of " oh , oh ! " were already rising in the pit and the cheap places . there was a sound of whistling , too , when a voice in the stalls , suggestive of a molting cockerel , cried out with great conviction 后座和廉价座里发出“哟，哟”的叫声，还有人吹起口哨，这时候，前座里响起了一个少年发育期变嗓的声音，一本正经地嚷道： “太棒了！ ”
At 27 - 29 , the process needs about 50 hours . at 21 - 22 degrees the process needs approximately 110 hours . after molting for the sixth time , the larva enters the zoea stage 无节幼虫虫随著脱皮体形渐大，共有六期，第一期到第六期所需时间依水温高低有所不同，通常在27 29之下约50小时， 21 22之下则约需110小时，于第六次脱皮后即进入眼幼虫期zoea stage 。
The ion exchange quomodo was innovated , and the idea was first brought forward that the ion exchange reaction were occurred after the precursors were pretreated . the ion exchange reaction in molt salt was further studied 本论文对离子交换反应的方式进行了创新，首次提出先将前驱体进行预处理再离子交换的思想，并对熔融盐介质中进行的离子交换反应做了深入研究。
Suggesting that the larvae of spodoptera exigua died more quickly when fb - 28 were added to the virus . the larvae of spodoptera exigua inoculated as newly molted fourth instars ( 40s ) and at various hours after molting ( 316s ) , we sacrificed larvae at various time intervals after inoculation to process the larvae for lacz expression in midgut by using tissue section techniques on early phase infection 此外，对于处于不同虫龄的幼虫进行病毒感染时发现：对3 ~ ( 16 )幼虫毒力生物测定时，荧光增白剂的增效作用达到50 ，但对4龄初的供试幼虫进行测定，荧光增白剂的增效作用却不很明显，仅为10 。
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 " 眼幼虫脱第三次即进入糠虾期幼虫期mysis stage ，此期之体形已略成虾之状态，且具特有之游泳姿态，即头部及尾部均向下，成一直角弯曲而时作向后跳跃游动，又因成倒立状态，悬浮于水中的中上层，又叫倒吊期，此期幼虫对外界的环境因素，如水温盐分等变化，比前两期来得更具适应力，主要饵料为丰年虾brine shrimp的幼虫，但其他大小略同的动物性浮游生物，如桡脚类copepoda轮虫类rotifera均可。
