The lipid content of the fish ranged from 8 . 72 to 14 . 3 % based on the body weight and from 30 . 5 to 43 . 7 % on the dry mass , which indicated that its lipid content was higher than those of the most reported species 381d 。通过讨论发现，雌、雄鱼体在繁殖前后的能量密度的差异不显著，由此可知雌、雄鱼体在繁殖过程中所需的能量来自于摄食；该种鱼的脂肪含量占体重的变幅为8
( 2 ) the metabolic rate in m . macropterus was higher than that in either s . meridionalis or s . asotus could be understood on the different ecological habits among them . for example , the level of spontaneous activity in m . macropterus was higher P ）大鳍鳍的代谢率高于南方贴和稣鱼的代谢率是因其生态习性不同：一）大鳍鳍的自发活动的行为比其他两种鱼更为频繁，因而所测其静止代谢水平较高。
And the level of routine activity of the tested fish in large - scale closed respirometer in this study was higher than those of the either , which was restricted by the smaller room of respiratory chamber in the continuous - flow respirometer used in the two reported studies . O ）本实验采用的是大型封闭式呼吸室，对实验鱼的日常活动的限制作用较小，而其它两种鱼采用的是小型流水式呼吸室，限制了鱼体在测定过程中的活动性。
Relying on its experience in production of fish meal processing equipment of many years and by reference to the advanced overseas technology , the plant has successfully developed about one hundred products of fish meal processing equipment in three series covering more than 20 models and sizes and owns four chinese patents 根据多年生产鱼粉加工设备的经验及国外的先进技术，成功的设计出三大系列、二十多个型号规格，近百种鱼粉加工设备，并拥有四项国家专利。
( 5 ) based on the models reported the standard - weight metabolic rates of s . meridionalis and s . asotus were estimated . the metabolic rate in m . macropterus was 1 . 82 and 1 . 49 times of those in s . meridionalis and s . asotus , respectively . the discussions suggested : ( 1 ) due to the effect of body weight on the metabolism might be brought into antagonism with that of developmental condition of the gonad , the difference between the metabolic rates in the tested fish at the different condition was insignificant 5 )以本研究中的大鳍鲮的平均体重值( 94 . 5g )为标准体重，采用文献报道的南方鲇( silurusmeridionalis )和鲇鱼( silurusasotus )的静止代谢率模型，计算了两种鱼在本实验各温度下的静止代谢率，比较分析发现大鳍?的代谢率分别为南方鲇和鲇鱼的1 . 82和1 . 49倍，表明大鳍?的代谢率高于前两种鱼。
The metabolic rate in pelteobagrus vachelli ( richardson ) was higher than those two fishes under this study temperature respectively . the discussions suggested : the metabolic rate in pelteobagrus vachelli ( richardson ) was higher than that in either silurus meridional is or silurus asotus could be understood on the different ecological habits among them . for example , the level of spontaneous activitie in pelteobagrus vachelli ( richardson ) vas higher ( 4 )以本研究中的瓦氏黄颡鱼的平均体重值( 8 . 3g )为标准体重，采用文献报道的南方鲇( silurusmeridionalis )和鲇鱼( silurusasotus )的静止代谢率模型，计算了两种鱼在本实验各温度下的静止代谢率，比较发现在各个温度下瓦氏黄额鱼的静止代谢率高于前两种鱼。
The context in this paper includes the tactical demand of modern torpedo homing system , the advanced algrithm , the application of dsp in torpedo homing system outside country and the basic algrithm of homing signal processing . the basic structure of dsp signal processing procedure , homing and its algorithm assembly flow chart is also introduced in this thesis 本文介绍了现代鱼雷自导战术要求、先进算法及国内外dsp在鱼雷自导中的应用现状；阐述了鱼雷信号处理的基本算法；并对dsp的结构及其应用作了详细的说明；还介绍了各dsp信号处理模块的基本结构、自导流程图及某种鱼雷自导算法的流程。
American food and medicaments management board once also announced 4 kinds of fish this year in january ( fish of head of shark , horse , dorado and majia fish ) mercuric content is exorbitant , knife of head of the tuna that this report suggests pregnant woman should reduce edible can again , ghost , cod reachs narrow cod , because the mercuric content of this kind of potted fish is very high also , edible also answer with mensal in the limit of 美国食品及药物治理局今年1月也曾经公布4种鱼类(鲨鱼、马头鱼、剑鱼及马加鱼)水银含量过高，该报告又建议孕妇应减少食用罐头的金枪鱼、鬼头刀、鳕鱼及狭鳕鱼，因为这类罐头鱼的水银含量也很高，食用也应以每月一次为限。
