燕山运动早期形成早侏罗世断陷盆地和中侏罗世挤压坳陷型聚煤构造盆地；中期中晚侏罗世形成被NW、NE向深大断裂围限的火山断陷盆地，中基性—酸性火山喷发和浅成、超浅成中酸性岩浆侵入，晚侏罗世末形成了一系列NNE向褶皱和逆冲推覆构造带；晚期早白垩世再次形成断陷盆地和开阔平缓褶皱，义县组不整合在火山岩之上，晚白垩世处于挤压造山后的山体隆升阶段，左云组不整合在义县组之上，伴随有壳源型花岗岩侵入，NW、NE向断裂复活，形成地堑、地垒式断裂组合，导致山体隆升。

In the mixed sulfate-metavanadate melts, the oxides formed orthovanadate acidic solutes with a solubility much higher than the corresponding acidic sulfates for the pure Na_2SO_4 melt.

在混合盐熔体中，氧化物形成正钒酸盐酸性溶质，溶解度高于其在相应的酸性纯Na_2SO_4熔体中的溶解度。

Variance in chemical components of the former is similarto the latter;the content of α-cellulose,lignin increase with the growth of age,the content of extract,hemicellucose,polysaccharose and mineral elementsdecrease with the grow of age;pH value is acid and increase with growth.

早园竹的化学成分含量随年龄的变异规律基本类似于毛竹，α-纤维素含量、木质素含量随着年龄增大而增大；抽提物、半纤维素、聚戊糖、灰分含量随着年龄增大而降低；pH值呈酸性，酸性随着年龄增大而减弱。

The colon temperatures were measured by a thermistor and the cytosolic free calcium concentration ([Ca2+]i) in dissociated brain cells was measured by Fura 2-AM. The results demonstrated that the pyretic action of egtazic acid (0.6 μmol, icv) was markedly inhibited by DEX (5 mg/kg,iv), but DEX (60-120 μmol/L) did′t affect [Ca2+]i in dissociated hypothalamus cells. Actinomycin D, which interferes with gene transcription (3 nmol, icv), completely abolished the antipyretic action of DEX on egtazic acid-induced fever.

结果发现：脑室灌注乙二醇双(2-氨基乙醚)四乙酸(0.6 nmol)引起家兔结肠温度明显升高，静脉注射地塞米松(5 mg/kg)显著抑制家兔乙二醇双(2-氨基乙醚)四乙酸性发热，地塞米松(60-120 μmol/L)并不影响下丘脑细胞内[Ca2+]i，而事先脑室灌注抑制基因转录的放线菌素D(3 nmol)则完全取消了地塞米松对乙二醇双(2-氨基乙醚)四乙酸性发热的解热作用。

The arrangement mode of acid orange in the interlayer of the LDH is slantwise double layer and the angle tilted is 45°.

酸性金黄阴离子以补偿LDH层板电荷的形式嵌入到层间。嵌入到层间的酸性金黄阴离子以双层倾斜45°方式排列。

First,through monofactorial experiment,we studied the influences of pH,temperature and substrate concentration on acidic trehalase activity of baker's yeast.

首先通过单因素实验研究了pH值、温度、底物浓度对面包酵母酸性海藻糖酶活性的影响，然后通过正交试验得出了酸性海藻糖酶活性测定的适宜条件：海藻糖浓度1.6%、温度30℃、pH 4.0、酵母菌泥接种量为0.02g/mL。

First, through monofactorial experiment, we studied the influences of pH, temperature and substrate concentration on acidic trehalase activity of baker's yeast. Then we designed an orthogonal experiment to detective the optimal condition of ascertaining acidic trehalase activity. The optimal conditions are: substrate concentration 1.6%, pH 4.0, temperature 30 and seed volume 0.02g/mL compressed yeast.

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。
