Prostaglandins secreted from placenta and fetal membranes during pregnancy play important role in fetal development and initiation of parturition.

前列腺素是妊娠期宫内组织分泌的一种重要激素，在人类的妊娠和分娩过程中发挥着重要的作用，其浓度受到前列腺素合成酶与代谢酶的共同调节。

The changes of the fruit cells during ripening and softening were studied used the scanning electron microscopy . A pectate lyase and a β-galactosidase gene were also cloned from mature banana fruit by RT-PCR and the expression of them were investigated by the semiquantitative RT-PCR.

主要结果如下： 1 通过对香蕉果实成熟软化过程中相关酶类，特别是近年报道的与果实成熟软化相关的13种酶活性的变化进行了研究，证明这些酶的活性变化多与香蕉果实成熟软化相关。

Especially, the Rubisco activase as well as whole enzyme of Rubisco were distributed in the starch sheath and the surface of pyrenoid. It was demonstrated the pyrenoid had close relationship with photosynthesis.

此外小球藻Rubisco全酶的分子定位也表明全酶在蛋白核的表面较多的分布，从而进一步证明蛋白核与光合作用关系密切，并且蛋白核的光合功能可能主要在其表面。

We studied the growth state of tomato seedlings and the adaptive changes in activity of tonoplast H+-ATPase on different days (5 d,7 d,9 d,11 d,13 d) sampling from the roots of tomato seedlings under phosphorus starvation.

磷饥饿提高了番茄幼苗根部液泡膜H+-ATPase的水解活性，随着磷胁迫时间的延长，该酶的活性逐渐增大，在磷饥饿7d时达到最大，后又略有降低；而对照番茄幼苗根部该酶的活性变化很小。

The advances of the composition and function of xanthophyll cycle in higher plants, the structure, biochemical properties and regulation of violaxanthin de-epoxidase and zeaxanthin epoxidase, and convertibility and localization of xanthophyll during the last few years are reviewed.

对近几年来植物体内叶黄素循环的组成、能、菜黄素脱环氧化酶和玉米黄素环氧化酶的结构、化性质和调节，以及叶黄素的可转变性、位等方面的研究进展作了综述。

From the results, it seems that this new macrocyclic ligand is able to bind three different amino acids with selectivity in aqueous solution, and the strength of binding is of the order lysine＜glycine＜aspartic acid.

通过合成金属配合物，在结构和功能上模拟生物酶的活性中心或结构中心是研究酶的结构与活性关系的重要手段，也是生物无机化学的一个主要研究方向。

The partial N-terminal amino acid sequences of LccA and LccB were AIGPK and GIGPV, which show high homology to those of the laccases of other white-rot basidiomycetes.

用SDS-PAGE测定两漆酶的分子量分别为64.2ku和60.7ku；LccA和LccB的最适作用温度分别是40℃和50℃；最适反应pH值为3.5和4.0；其N-末端部分氨基酸序列为AIGPK和GIGPV，与其他真菌漆酶相比显示很高的同源性，以ABTS为底物的Km值分别为68.96μmol／L和76.92μmol／L。

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。
