The organic acids in liquor are classified into volatile acids and involatile acids .

白酒中有机酸分为挥发酸和不挥发酸，白酒中的不挥发酸有乳酸、柠檬酸、酒石酸、苹果酸、琥珀酸等。

The cell suppression ratio and surviving ratio were detected respectively under conditions of simple hypoxia, or 5mmol/L glucose complicated with hypoxia. The mRNA levels of key enzymes that are involved in regulating glyco-metabolism were detected, including the mRNA levels of pyruvate-kinase, hexokinase, succinic dehydrogenase and isocitric dehydrogenase, and the activity of lactate dehydrognase.

以SMMC-7721人肝癌细胞和L02正常肝细胞作为研究对象，分别在单纯缺氧及加葡萄糖缺氧条件下，观察细胞生长，并检测糖代谢关键酶：丙酮酸激酶(pyruvate-kinase， PK)、己糖激酶(hexokinase， HK)、琥珀酸脱氢酶(succinic dehydrogenase， SDH)、异柠檬酸脱氢酶(isocitric dehydrogenase， IDH) mRNA表达水平和乳酸脱氢酶(lactate dehydrogenase， LDH)活性。

In this article, high-pure lactic acid and ethanol acid were used to synthesized PLGA by direct condensation polymerization, and zinc octanoate of low nocuity was used as katalyst, instead of stannous octanoate to synthesize PLGA by the way of opening ring.

本文首次采用高纯度乳酸、乙醇酸直接缩聚合成无催化剂的端羧基PLGA，并分别采用了低毒性辛酸锌代替辛酸亚锡为催化剂通过开环聚合法合成端羧基／酯封端PLGA。

The hepatic glycogen and the activities of ACP, LDH, returned to normal at 7th postoperative day in the Labiatae group.

3丹参组术后3天琥珀酸脱氢酶、镁离子激活三磷酸腺苷酶、葡萄糖-6-磷酸酶活性升高，术后7天肝糖原和乳酸脱氢酶、酸性磷酸酶活性回到正常水平。

Using blood lactid acid index, the authors assess the results of practising methods such as " sand bag"," wheel combat "and u actual combat.

运用血乳酸指标，对散手训练中采用的&砂袋&、&车轮战&、&实战&等训练方法的效果进行评价。

They reveal that practising "sand bag "five round is a better way to increase the specialized endurance of the unarmed combatants;In the competitions and practices,the values of blood lactid acid are significantly different.

结果表明，5局砂袋训练是提高散手运动员专项耐力的较好方法；在散手比赛和散手训练中，血乳酸值差异非常显著。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
