酸性的

"The thought has been that as ocean's acidify, the cost of calcification will continually go up," and organisms will be less likely to do it, says Robert Steneck, a marine biologist at the University of Maine, Orono."Their findings are surprising, to say the least."

"他们的观点是，随着海洋酸性的增加，海洋生物进行钙化的代价会不断地加重，因而它们的应对能力将会下降，"缅因大学奥罗诺分校的海洋生物学家罗伯特·斯特耐克说，"至少可以说，他们的发现是令人惊讶的。"

It includes determination of properties of the acid protease and lipase, application of acid enzymes to processes of bating pickling pelt and wet blue of sheepskins, analysis of activities of collagenase in acid protease and trypsin. Comparison was conducted to acid bating and common bating. Orthogonal experiments were used to determine influence of some factors in acid bating on qualities of leather. Scanning electronic microscope was used to observe separating of collage fibers.

Accord- ing to the observation that the compounds were stable in low pH aqueous solution and their sta- bility decreased when pH increased, and they rapidly decomposed to form α-methylenecyclopen- tanones derivative when pH reached 6 to 7, we postulated that the compounds were unabsorbable in stomack (where pH1-3) and unstable in small intestine (where pH5-8). The decomposed product was indeed inactive.

对Ⅰ类化合物在稀溶液中的稳定性研究表明，低pH时化合物较稳定，随着pH值的升高稳定性逐渐降低，pH6~7时，化合物迅速分解成α-亚甲基环戊酮类化合物，由此而推测Ⅰ类化合物经口给药无效的原因为：它们在强酸性的胃中（pH1-3）呈离子状态，因而不易吸收，经胃的排空运动进入肠道后，随着pH逐渐升高（pH5-8）化合物迅速分解，而分解产物α-亚甲基环戊酮类化合物证明是无效的。

According to authigenetic mineral association and nowadays stratum geochemistry character, combining the diagenesis character of sandstone in coal measure strata, it is thought to the fluid of outcrop sandstones went through ealy acidity- acidity-alkality-surficial acidity 4 fluid phases, the fluid evolution of core sandstones is ealy acidity- acidity- nowadays alkality 3 fluid phases.

由自生矿物组合以及现今地层水地球化学特征，结合煤系地层砂岩成岩作用特征，认为露头砂岩的流体经历了早期酸性－酸性－碱性－地表酸性4个流体阶段，岩芯砂岩的流体演化为早期酸性－酸性－现今碱性3个流体阶段。

From the Late Carboniferous to the Permian, Junggar region into the post-collision tectonic evolution stage, in the stage of the post-collision, the early subduction slab rupture and separate, asthenosphere decompression melting, basalt magma take place underplating, because the underplating of the basalt magma, low crust melt by the high temperature forming the acid crust-magma, the basic magma from mantle and acid one from crust mixing at the vicinity of the crust-mantle boundary, formed the Huangyangshan magma mixing plution, the dioritic microgranular enclaves are the recorder of the crust and mantal magma mixing process.

从晚石炭世到二叠纪，准噶尔地区进入后碰撞构造演化阶段，在后碰撞构造阶段，早期的俯冲板片断离，软流圈减压熔融，玄武质岩浆底侵至下地壳底部，底侵基性岩浆带来的巨大热量，导致地壳物质熔融，形成大规模的花岗质岩浆，两种岩浆在壳-幔边界附近发生不同程度的混合，其中闪长质微细粒包体就是基性的幔源岩浆和酸性的壳源岩浆不同程度的混合的记录者。

Increased accumulation of acidic fibroblast growth factor in left ventricular myocytes of patients with idiopathic cardiomyopathy.

在病人的左方的心室的myocytes与先天的心肌症增加了酸性的纤维原细胞生长因素的累积。

Metal corrosion in sulfuric aeid edw point is a common and very serious harm go the corrosion forms, in a wide range of production in all aspects of life, especially in some specific process unit operation equipment middle.low-temperature corronsion dew point in the general industrial rurnace, boiler, fuel saving edvices, air preheater, heat exchangers, tower refrigeration systems, dust, garbage incineration furnace, sintering furnace flue and chimney acid plant and the wind tunnels of hypothermia sife, yes containing gurnace flue and chimney acid plant and wind tunnels of hypothermia site, yes containing acidic gases produced by the condensation of cold treatment from the local cold drinks along with the liquid in the device, lesding to a very serious material corrosion.

金属材料的硫酸露点腐蚀是一种常见的，危害十分严重的腐蚀形式，广泛的发生在生产生活的各个方面，尤其发生在一些特定的过程单元操作设备中间。低温露点腐蚀一般发生在在工业加热炉、锅炉、燃料节省器、空气预热器、热交换器、塔顶冷凝系统、除尘器、垃圾焚烧炉、烧结炉、烟道，烟囱及酸厂的引风管道等的低温部位，是含酸性的气体经由该产遇冷冷凝下来的冷饮液局部地随着于设备上，从而造成对材料极严重的腐蚀。

抗干旱的亚洲象树的灌木，长有酸性的小的可食用的果实，通常被用在冰冻果子露中。

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.
