Results showed that compared with the normal group, vitamin D deficiency had no significant effect on the weight gain rate ( WGR) and daily increment in shell length ( DISL) ( P> 0.05);

结果表明：与维生素D正常添加组相比，维生素D缺乏对皱纹盘鲍的增重率（WGR）和贝壳日增长（DISL）均没有显著差异（P>0.05）；

That suggested WGR was a structure-sensitive reaction.

实验结果表明，CO水汽变换反应是一个结构敏感型反应。

When dietary protein content was as low as 20%, WGR and body crude lipid contents were significantly lower.

WGR of 50% group was 95% of 54% group and got the best protein efficiency ratio.

50%蛋白组增重率能达到54%蛋白组的95%；蛋白质效率最大；

WGR of the seventh group was the smallest, it was 151.66%.

第7组的相对增重率最小，为151.66%。

Weight gain ratio ( WGR), special growth rate ( SGR), feed efficiency ( FE) and, protein conversion efficiency ( PCR) of fish were improved by the elevation of dietary phosphorus level and reached maximal value at 1.32% total phosphorus.

随着饲料中磷添加水平的提高，黑鲷幼鱼的增重率、特定生长率、饲料效率和蛋白质效率呈上升趋势，当饲料总磷含量为1.32%时，各项指标均达到最高水平。

Result showed that the stocking densities for turbot had significant influences on SGR, WGR, average daily gain, rate of daily gain and feed coefficient.

实验结果表明，养殖密度对大菱鲆的比生长率（SGR）、增重率（WGR）、平均日增重、日增重率和饵料系数均有显著的影响（P0.05）。
