查询词典 acidic

The main content of this paper as follows: The acidic strength, reaction temperature, reaction time of Chlorine-aluminate Ionic Liquids with different structure of cation on the activity of transalkylation of MN with TeMB and the selectivity of 2,6-DMN were studied. The optimum reaction condition was obtained: the molar fraction of AlCl_3 is 0.71, molar ratio of 2-MN and TeMB is 1, the amount of ionic liquid is 32wt%, reaction temperature is 20℃and reaction time is 8h using X-xAlCl_3 and X-xAlCl_3 as catalysts; the optimum reaction time is shortened 6h using Et_3NHCl-xAlCl_3 as catalyst.

本文主要研究了以下内容：分别考察了不同阳离子结构的氯铝酸盐类离子液体的酸强度、反应温度、反应时间等因素对MN和TeMB转移烷基化的催化反应活性和2，6-DMN选择性的影响，优化得到适宜的反应条件为：以X-xAlCl_3和X-xAlCl_3为催化剂时，AlCl_3的摩尔分数x=0.71，2-MN和TeMB摩尔比为1∶1，离子液体用量为32wt％，反应温度为20℃，反应时间为8h；以Et_3NHCl-xAlCl_3为催化剂时，反应时间缩短到6h。

In fact, many prefer its mild acidic flavor to Kona's sometimes too-delicate taste.

事实上，许多喜欢它的味道科纳轻度酸性的，有时过于敏感口味。

Despite ready access to the sea food, Liguria's best-known food is land-based in origin. Focaccia, the locals' answer to pizza, is right-angled cuts of tasty bread made with little more than flour, salt, olive oil and a few extras than vary depending on which town along the Italian Riviera you visit. The tastiest type hails from Recco, where Stracchino cheese ( Stracchino is a type of Italian cheese, typical of Lombardy which derives from the Italian word "stracca", meaning "tired". It is said that the milk from tired cows is richer in fats and more acidic. It is eaten very young, has a soft, creamy texture and normally a mild and delicate flavour. It is normally square in form.) gets sandwiched between two layers of bread and then served piping hot. Those not keen on stand-up lunches among the sun-lotioned throngs have plenty of alternatives though as rustic eateries are plentiful around Santa Margherita Ligure.

在乐乔亚区虽然海产唾手可食，可是最吸引人的美食还是当地类似 Pizza 整齐切片的 Focaccia 面包，口味与配料延著义大利 Riviera 地区而异，主要是由面粉、盐、橄榄油与洋葱等额外配料烤成，最美味的是来自 Genova 省 Recco 区的 Stracchino 起司夹心热三明治( Stracchino 起司是 Lombardy 地区的典型起司，Stracchino 源自义大利文"stracca"，原意是疲倦，产自疲倦乳牛的牛乳据闻更富脂肪与酸性；趁鲜食用，乳脂柔软富香气，以块状包装)，它并非渴望在艳阳下囫囵吞枣的五脏庙祭品，但环绕 Santa Margherita Ligure 地区却有许多乡间小馆可让大家选择。

And it should be treated with limestone if the soil is acidic.

如果土壤是酸性的话，草坪还面临着石灰岩的威胁。

Blue litmus paper is to use to test for acidic, where as red litmus paper is to use to test for alkaline substances.

酸性的物质具有极酸的味道。它可把蓝色石蕊试纸变成红色。物质如：酸奶、醋、柠檬、杨桃、橙

Ammonifiers in Suzhou Creek can not use inorganic nitrogen and carbamide as nitrogen source; additional carbon source and garbage lixivium have little influence on ammonifiers growth; high content of salt and low temperature restrain ammonifiers growth; alkalescent condition has little influence on ammonifiers, but acidic condition restrain ammonifiers growth; the biomass of ammonifiers are not necessary correlated with the function of ammonifiers, adding glucose with 1g/l content into the water sample obviously promote the growth and function of ammonifiers.

苏州河的氨化菌无法利用无机氮和尿素作为氮源；在营养条件充足时添加额外C源和富含有机物的垃圾浸出液对氨化菌的生长基本无影响；高盐度和低温抑制氨化菌生长；碱性条件对氨化菌的生长影响不大，酸性条件对氨化菌生长具有抑制作用；氨化菌生物量的消长与转氨活性之间不存在必然联系，1g/L的葡萄糖对苏州河水样中氨化菌的数量和转氨功能具有明显的促进作用。

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.
