Secondly, the genomic DNA is extracted from Zostera marina L. and then amplified by PCR with two oligonucleotide primers synthesized to obtain the partial nucleotide sequences of the Na~+/H~+ antiporter gene. The Na~+/H~+ antiporter gene clone was obtained after a series of manipulation: purificatioin of PCR product, ligation and transformation of recombinant plasmids, blue-white selection and so on. DNA sequence analysis shows that its DNA sequence is highly homologous with the genomic DNA sequence of E.

Under the 6 h stress, SOD activity had been to maintain a high level, POD activity showed a greater change. When the stress lasted until 24 h, POD activity decreased and almost flatted compared with the control, this showed that POD activity was sensitive under the low temperature stress. Changes of CAT and SOD activity were in the line, the results indicated that activity of two enzymes coordinated the regulation of low-temperature adaptation.

本实验中，SOD活性一直保持较高的水平；POD活性表现为波动较大，当胁迫持续到24 h时，POD活性明显降低几乎与对照持平，说明POD受低温影响更敏感；CAT活性与SOD活性变化保持一致，表现出这两种酶在低温适应性调节过程中的协同作用。

Results: In HPC and Z n2+ induced groups, all the contents of MT and the activities of antioxida ses were obviously higher than those in H/R (P.05,P.01 respectively ). While using MT, the activities of SOD were progressively increased than contr ol(P.05), CAT and GSHpx activities were lower than control(P.01), bu t were significantly higher than those in I/R group(P.01). In MT antibody g roups, the activities of antioxidase were decreased extremely.

The cylindrical film holes are 45° inclined and perpendicular oriented, there are totally fourteen holes placed on one ribbed wall. Geometrical parameters such as rib angle (45°, 60°, 90° and 120°), rib height (h/e=1.0, 2.0), location of the hole relative to rib on the discharge coefficients and pressure loss characteristics are all studied systematically.

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.
