| 1. | Their physiological significance is obscure .
它们的生理功能是含糊不清的。 |
| 2. | However , pca has a main defect that its analysis result component has neither anatomical nor physiological significance
但主成分分析的一个主要缺点是作为分析结果的成分既没有解剖学也没有生理学上的意义。 |
| 3. | " the physiological significance of our findings and their relationship to the interplay between chronic sleep debt and metabolic disorders like obesity and type 2 diabetes remain to be established , " the investigators note
“该发现的生理学重大意义及其对长期睡眠不足与代谢异常如肥胖和2型糖尿病间相互影响的关系尚未确定， ”研究人员称。 |
| 4. | Although cftr has been implicated in bicarbonate secretion , its ability to directly mediate bicarbonate secretion of any physiological significance has not been shown . professor chan demonstrates that endometrial epithelial cells possess a cftr - mediated bicarbonate transport mechanism
陈教授与其研究队伍发现， cftr作为一个阴离子通道，可以调节子宫内碳酸氢根（ hco3 - ）的分泌，从而影响精子的受精能力。 |
| 5. | So eegs contain large amount of original information about the activity of the human brain . the studying of eeg signals can help us to know well the connections between the electrical activity of neuron and the physiological and / or psycho - physiological significance
通过对脑电信号的研究可以使我们更好地了解神经元电活动与人的生理和心理状态之间的关系，这在临床医学和认知科学领域都只有极其重要的意义。 |
| 6. | The purpose of eeg signal processing is to extract the hidden or weak patterns that probably have some physiological and / or psycho - physiological significance from eeg signals in sophisticated noise background and then to apply them to the research on clinical medicine or cognitive science
我们对脑电信号处理的目的就是为了从复杂的背景噪声中分离出有用的脑电信号，进而从中提取出具有明确生理意义的脑电特征，并应用于临床医学和脑认知科学的研究。 |
| 7. | When some certain assumptions are satisfied , ica can effectively separate the independent source signals from the synchronous multichannel recording , and then according to some independent sources , we can further analyze their physiological significance . therefore , as a new promising approach of blind source separation ( bss ) , ica has attracted extensive attention of researchers in the international field of signal processing
在满足一定的条件下， ica能够从同步测量的多路线性混合信号(如思维脑电和诱发脑电)中分离出相互独立的源信号，根据所提取出的独立分量，我们可以进一步获取和分析隐含在原始信号数据中的重要特征。 |
| 8. | However according to the view of acoustics , click includes mixed frequencies , so further studies are necessary to investigate the physiological significance of amygdaloid modulating effect on the ascending auditory information at the cortical level . in this paper we firstly observe the characteristics of the acoustic response of neurons in a - i evoked by pure tone ; then investigate the influence of la stimulation on the acoustic response of these neurons and the physiological significance of such influence ; revea l the neural pathway mediating this effect with the neurohistological method ; and study the neurotransmitter and its receptor participating in this effect
本文采用电生理学方法考察大鼠皮层a区神经元纯音反应特征，观察杏仁外侧核( la )对a区神经元声反应的影响，运用神经组织学方法揭示介导这一影响的神经环路，采用多管微电极记录结合微电泳技术的方法研究参与这种影响的神经递质及受体，进一步探讨了这种调制性影响的生理学意义。 |
