Methods: four male volunteers were recruited to live in a disabled submarine simulator which is close, dark and algid for 10 days. they were supplied 1.5 l water and one portion of saving life dry provision everyday. the body weight was detected before the experiment and on day 3, day 4, day 5 and day 10 after exposure. at the same time, venous blood taken suction from elbow was used to detect the level of blood glucose, which was centrifuged to take the upper serum to detect the level of ffa at low temperature by colorimetric.

4名男性受试人员在封闭、黑暗、寒冷的试验舱体中进行为期10 d的模拟失事潜艇环境实验，每人每天供水1.5 l和1盒救生压缩干粮，实验前和第3、4、5、10天出舱的晨起测定体质量，抽取肘部静脉血，测定血糖；低温离心留取上层血清，采用一次提取比色法测定游离脂肪酸。

Based on the absorbance change of indicators with the concentration of hydrogen ion released from the enzyme-catalyzed reaction, a convenient colorimetry method is established for the assay of acidic phospholipase 〓 and glycogen phosphorylase b Brilliant yellow and bromothymol blue are chosen as indicators for assays of acidic phospholipase 〓 and glycogen phosphorylase b by following the absorbance changes at 495 nm and 615nm respectively The method is simple, sample-saving, sensitive and valid for a wide range of enzyme concentrations.

为了研究糖原磷酸化酶的激活动力学和酸性磷脂酶〓的复性过程，我们根据酶催化反应中释放氢离子浓度的变化引起相应的指示剂的光吸收发生变化的原理，建立了一种简捷的比色法，用于测定酸性磷脂酶〓和糖原磷酸化酶b的活性。选用亮黄和溴麝香草酚兰分别作为酸性磷脂酶〓和糖原磷酸化酶b测活的指示剂，在495 nm和615 nm处检测二者的光吸收值的变化，可以测定酶活。本方法的优点是，可在比较宽的酶浓度范围内进行活力测定，而且操作简单、节省样品、灵敏度高。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
