Because of the infection of the animalcule's secretions, and the alkalescent shampoo or soap, or any other reasons, the acidic barrier is often destroyed. Once the PH value increase to the alkalescence level, the natural bacterium group will be resisted by the nosogenetic bacterium, and then leads to the inflammation.
由於微生物分泌物的影响,使用碱性香波、香皂洗头、洗脸的影响,或其他原因,其酸性屏障会遭到破坏,PH值升高到碱性范围时,正常菌群即会被致病菌压制从而发生感染。

As a result, the author discusses the thermodynamics habitus for the minerals either. With the calculation of the thermodynamics modeling, we run the dissolutionmodeling experiments for primary minerals (potash feldspar, albite, anorthite, andpyroxene, hornblende), which is under the conditions of organic acidic and 20 varietytemperature and pressure. The dissolution modeling experiments include 4 anorthitedissolution experiments, 8 pyroxene dissolution experiments, 8 hornblendedissolution experiments. We catch the records on the X ray diffraction, chemistryanalysis, SEMphotos, and the PH parameters. By theway, we discuss the dissolution habitus for the minerals either.

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。
