查询词典 porgy

The change of frequency, draws the conclusion through observing fish's respiratory rate and coughing: Luo is not the respiratory rate of fish and bright cloud porgy, drop with increase of Cu2+ density, cough frequency increases with increase of Cu2+density; Respiratory rate and frequency of coughing of black carp, appear downward trend after rising with Cu2+ increase of density first.

通过观察鱼呼吸频率和咳嗽频率的变化，得出结论：罗非鱼和彩云鲷的呼吸频率，随着Cu2+浓度的增加而下降，咳嗽频率随着Cu2+浓度的增加而增加；鲫鱼的呼吸频率和咳嗽频率，随着Cu2+浓度的增加都呈现先上升后下降的趋势。

Thus it appears that porgy was more sensitive to the WAF than scorpionfish at the low dose, but less tolerant at the high dose.

所以对于0#柴油认叭F而言，黄鳍绸比褐葛鳅更为敏感，但对诱导物的耐受性较低，EROD活性诱导范围较狭窄。

In this study, the malondialdehyde content, the glutathione peroxidase activity, and the superoxide dismutase activity in black porgy Sparus macrocephalus were determined after the acute exposure to TBTCl at the concentration of 4 and 20 μg·L-1. Results showed that TBTClinhibited the SOD activity in S.macrocephalus gill slightly , but there was an obvious promotion on the SOD activity in S.macrocephalus liver.

摘 要：观察和比较了黑鲷 Sparus macrocephalus 在不同浓度的氯化三丁基锡（tri-n-butyltin chloride，TBTCl）溶液中暴露后，其鳃和肝脏组织中超氧化物歧化酶（superoxide dismutase，SOD）活性、丙二醛（malondialdehyde，MDA）含量和谷胱甘肽过氧化物酶（glutathione peroxidase，GPx）活性的变化情况。

Besides, we firstly confirmed at the molecular level that P450arom may play an important role in the natural sex change of protandrous fish and revealed that up-regulation of the transcript levels of P450arom during the course of natural sex change of black porgy is not regulated via FTZ-F1.;sturgeon sex related and sex linkage genes by candidate gene approach and suppression subtractive hybridization technique and expression patterns of these genes were also studied.

首次直接在分子水平证明芳香化酶基因可能参与了雌雄同体鱼类性别逆转的调控，而黑鲷性别逆转期卵巢中芳香化酶的表达量上调不是由FTZ-F1基因调控的；同时主要利用候选基因法和抑制差减杂交搜寻史氏鲟性别决定或性别特异性基因，并研究其表达情况。

The effect of pH on digestive enzyme activity of alimentary organs in yellowfin black porgy was studied in this paper.

摘 要：研究了pH值对黄鳍鲷肝、胃、肠3个部分主要消化酶（蛋白酶、脂肪酶和淀粉酶）比活的影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
