查询词典 carbonic acid

Seawater reacts with carbon dioxide to form carbonic acid, decreasing the pH of the oceans.

海水跟二氧化碳发生反应生成碳酸，降低了海水的pH值，结果对海洋本身的环境造成了影响，如：破坏珊瑚和其他水生动物的呼吸作用。

I say "could be converted" because regardless of the pH, there will always be some bicarbonate and carbonate present, but at some pH there are enough protons in solution that if they were combined with the bicarbonate and carbonate present, it would all be converted to carbonic acid.

我认为："可转换"，因为不论其ph值，也往往会有一些碳酸氢盐和碳酸盐，但在一些ph值有足够的质子的溶液中，如果他们有机地结合起来，与碳酸氢盐和碳酸盐结合，它都将转为酸性。

When carbon dioxide dissolves in water itforms carbonic acid.

二氧化碳在水中溶解后会形成碳酸。

Consider to discover, OSAHS patient appears because of relapsing in nightly Morpheus disease of blood of low oxygen, tall carbonic acid, consensual as disorder as parasympathetic nerve function, already made coronary heart disease (the cardiovascular disease such as CHD) sparks importantly element, can cause all sorts of rhythm of the heart wrong, aggravating cardiac muscle is short of blood, produce sudden death of heart source sex even. 1 O SAH S and hypertensive disease consider to discover, OSAHS patient's nightly small arousal can bring about sympathetic stimulant increase, adrenalin can nerve medium if adrenalin, go adrenalin secretes armour grow in quantity, heighten of material of phenolic amine of catechu of nightly make water.

探究发现，OSAHS患者夜间睡眠中因反复出现低氧、高碳酸血症、交感和副交感神经功能紊乱，已成为冠心病等心血管疾病重要的触发因素，可诱发各种心律失常、加重心肌缺血，甚至发生心源性猝死。1 O SAH S和高血压病探究发现，OSAHS患者夜间的微觉醒可导致交感神经兴奋性增强，肾上腺素能神经介质如肾上腺素、去甲肾上腺素分泌增多，夜间尿儿茶酚胺类物质增高。

The blood pressure of.1 of pathology physiology mechanism that SAS causes CVD breathes time-out to be able to bring about airframe in elevatory Morpheus anoxic, sympathetic is excessive and excited, element of serous catechu phenolic amine, kidney and hemal endodermis element are elevatory, bring about hemal easy of hemal convulsion; to shrink the function is disorder, can make blood-vessel flowing flesh happening reframes and fleshy, systemic blood-vessel obstruction adds element of the kidney when; is chronic and anoxic, system of hemal and nervous element is activationed, bring about blood pressure to lift. Obstruction of way of energy of life of patient of OSAS of disease of blood of 1.2 low oxygen increases, cause air current to interrupt, breath pauses, at the same time airframe gets used to low oxygen environment gradually, breathing centre drops to low oxygen and sensitivity of disease of blood of tall carbonic acid, breath suspends a frequency increasing, farther aggravating airframe is anoxic. 1.3 heads are self-adjusting the function drops normal person changes quickly in systematic circulation blood pressure when, the head can be passed adjust independently functional generation protects effect, make change of cerebral blood flow not big.

SAS诱发CVD的病理生理机制。1血压升高睡眠中呼吸暂停可导致机体缺氧，交感神经过度兴奋，血浆儿茶酚胺、肾素以及血管内皮素升高，导致血管痉挛；血管舒缩功能紊乱，可使血管平滑肌发生重构和肥厚，全身血管阻力增加；慢性缺氧时肾素—血管紧张素系统被激活，导致血压升高。1.2低氧血症OSAS患者气道阻力增加，造成气流中断、呼吸暂停，同时机体逐渐适应低氧环境，呼吸中枢对低氧和高碳酸血症敏感性下降，呼吸暂停次数增加，进一步加重机体缺氧。1.3脑自动调节功能下降正常人在体循环血压快速变化时，脑可通过自主调节功能产生保护效应，使脑血流量变化不大。
