PGAM活性测定采用3-磷酸甘油酸为底物，经烯醇化酶等一系列偶联，以340 nm波长在自动分析仪上测定，根据NADH吸光度变化可求出PGAM总活性。

Weight loss method,extraction and absorption photometry were adopted,the measurement results of these means were compared.

采用减量法、萃取法以及吸收光度法进行了组分测定，对比各方法的测定结果。

Cloning and sequencing of the genes coding a and 3 subunit of phycoerythrin of a red alga-Corallina officinalis are reported firstly(GenBankaccession number: AF510986). The sequence contain 1,140 nucleotide, including 10 nucleotide that locate in the upstream of the initiation codon ofP subunit, 534 coding for P subunit(coding 177 amino acid), 101 nucleotide for gene spacer and 495 nucleotide that draw near the 5 terminal of a subunit(coding 164 amino acid).

首次测定了珊瑚藻藻红蛋白α和β亚基基因的全序列(GenBank登录号：AF510986)，测定的基因序列长为1，140个碱基，包括β亚基起始密码子上游的10个碱基，6亚基编码区的534个碱基(编码177个氨基酸)，101个碱基的间隔区以及α亚基编码区近5'端的495个碱基(编码164个氨基酸)。

Objective: To establish and consummate the analysis method of plumbum in Chinese patent drugs by measuring harmful elements plumbum in Danzhixiaoyao Tablets.

目的：通过对丹栀逍遥片中有害元素铅含量的测定，建立和完善中成药中铅含量的测定方法。

The detection limit of the method was 1.7μg/kg, and the limit of quantitation was 5.6μg/kg. Conlusion: This method shows simple, accurate, rapid and good precision, and can be applied in the determination of plumbum in soy sauce.

The seeds are stratified under lab condition. The average of high temperature is 19.36℃(2～4 months), the embryo completes the differentiation of the seed leaf, the radicle and plumule in this period.

在层积过程中，定期测定了种子的呼吸速率，可溶性蛋白、还原糖、粗脂肪和有机酸的含量，同时还测定了过氧化物酶和过氧化氢酶的活性。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
