METHODS:(1) Neonatal rat cardiomyocyte hypertrophic response was assayed by measuring cell surface area and protein content;(2) ERKs activity was determined by Whatman Paper Filter method;(3) Intracellular free calcium concentration (［Ca2+］i) was measured using Fura-2/AM as a fluorescent indicator.

利用培养的新生大鼠心肌细胞，①以蛋白合成速率、蛋白含量及细胞表面积为心肌肥大反应的指标；②用滤纸法测定ERKs活性；③用Fura-2/AM作为钙荧光指示剂测定心肌［Ca2+］i浓度。

RESULTS:(1) ET-1 could increase total protein production, surface area, ERKs activity and ［Ca2+］i in cultured cardiomyocyte in dose-dependent manner at concentrations ranging from 10-9 to 10-7 mol/L. And this effect could be abolished by BQ123, an antagonist of ETA receptor, partly inhibited by PTX, but not by BQ788, an antagonist of ETB receptor.（2）The activation of ERKs and the increase of ［Ca2+］i induced by ET-1 were obviously inhibited by PD98059, a selective ERKs kinase inhibitor, and nifedipine, a calcium channel blocker, respectively. Both antagonists partially inhibited ET-1-stimulated cardiomyocyte hypertrophic response.(3) Staurosporine, a selective PKC inhibitor, could inhibit ET-1-stimulated cardiomyocyte hypertrophic response and increase of ［Ca2+］i, but not affect the activation of ERKs.

结果： ①ET-1浓度依赖性增加新生大鼠心肌细胞蛋白质含量和心肌细胞表面积、ERKs活性及［Ca2+］i浓度，以上作用可被ETA受体拮抗剂BQ123所完全抑制，被百日咳毒素部分抑制，而ETB受体拮抗剂BQ788则无效；②ERKs激酶特异性抑制剂PD98059可完全抑制ET-1激活ERKs的作用，钙通道拮抗剂硝苯地平可明显抑制ET-1介导的［Ca2+］i浓度增加，但二者皆仅部分抑制ET-1介导的心肌细胞肥大反应；③蛋白激酶C选择性抑制剂staurosporine并不能明显抑制ET-1介导的ERKs激活，但可抑制ET-1介导的的［Ca2+］i浓度增加及心肌细胞肥大反应。

Get a plastic tray whose bottom has about 4 to 8 times the surface area of the board, and put about 1/4 of etchant in the bottom.

获得一个塑料托盘，其底部有大约4至8倍，比表面积的董事会，并把约1 / 4蚀刻在底部。

When the tip of a thin and soft touch strawberries that when a small thorn, a surge of intoxicating scent will drift away in my mind, that even the delicate red flesh surface area and gently bite it "transformation" of the.

In fact, the process of fuel breakup and atomization is a kind of instability phenomenon of the liquid jet. In order to increasing the oil surface area and promoting efficient combustion, the instability process of the jet is always used to make the fuel atomization in engineering.

燃油的分裂与雾化过程实际上是液体射流的一种失稳现象，在工程上常常利用射流的这种失稳过程来实现燃油的雾化，以增加燃油的表面积提高燃烧效率。

MnO_x catalytic gauzes are analyzed using BET、SEM and IR before and after treatment. The result shows that the specific surface area, total pore volume and average pore size of MnO_x reduce dramatically, and the infrared absorption band of N-O enhances. The removal mechanism of NO_2 using MnO_x catalyzer is preliminarily believed as absorption-catalysis process.

对使用前后的MnO_x催化网进行线性扫描和红外光谱分析，得到使用后催化剂比表面积、总孔容和总孔面积明显减小，N-O键增多，初步分析认为NO_2被MnO_x催化网去除的机理为先吸附后发生催化反应为酸。

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.
