3凡有核仁外移的细胞，绝大部分为嫌色细胞，而在嗜色细胞中，尤其是在嗜酸性的细胞中极少见到这种现象，因此核仁外移和细胞的种类之间存在着一定的关系。

A simple and sensitive fluorescence quenching method is described for the determination of nitrite, based on the reaction of Safranine T with nitrite in acidic medium to form a new compound with lower fluorescence intensity.

基于在酸性介质中，NO-2与藏红T直接反应，使藏红T的荧光猝灭，加入强碱弱酸盐对体系有增敏作用，据此提出了荧光法测定痕量NO-2的新方法。

And forest soils are saltier and more acidic, compared with other types of plant cover such as crops or grasslands, the researchers found.

The result makes clear: CF surface acidity is luscious it is good to increase and increase effect of acid treatment of; thick saltpetre what round amount handles time as thick nitric acid to oxidize than air, when the time that handles CF when thick nitric acid is 20 Min, tensile strength of CF/TPI composite material and flexural strength rise respectively 10% with 14%, XPS shows CF surface active is right now luscious the group increases than was not being handled 35.89%.

结果表明：CF表面酸性官能团的数量随着浓硝酸处理时间的增加而增加；浓硝酸处理效果比空气氧化好，当浓硝酸处理CF的时间为20 min时，CF/TPI复合材料拉伸强度和弯曲强度分别提高10%和14%，XPS表明此时CF表面活性官能团比未处理增加35.89%。

Not tall to edaphic requirement, be fond of the relief tall dry, small acidity soil that contains a lot ofhumus, blame with earthy layer the sandiness soil with fecund and deep, wet, good drainage is most appropriate.

富含腐殖质的微酸性土壤，尤以土层深厚。肥沃湿润。排水良好的沙质土壤最为适宜。

Sapogenin used by industry but most yams, from which it is isolated, contain a mixture of sapogenins in the glycosidic form.

大多数苷元在C24或C28位有COOH基，故又称酸性皂苷；少数苷元只含醇羟基而呈中性，如人参皂甙、柴胡皂甙等。

Hontonyme EAY is a acidic remodeled enzyme for cellulose fibre with excellent nap-removing effect, suitable for the biologic polishing of cotton and other cellulose fibres, with little scathe on the fabric strength.

Hontonyme EAY 是一种酸性基因改性型的纤维素酶制剂，具有优异的去毛功能，适用于棉及其它纤维素织物的生物抛光整理，并对织物强度的损伤轻微。

The obtained activation barrier of β-scission of 1-butene is 217 kJmol^(-1) in the reverse reaction of ethene dimerization.

反应的逆过程也就是1-丁烯在酸性分子筛表面的1-丁基烷氧化合物发生B分裂反应，计算所得相应的l-丁烯B分裂反应的能垒为217kJmol^(-1)，远高于相应的乙烯二聚反应能垒。

ConclusionIn the warm, humid and acidic circumstance where is benefitial to hyphal growth and reproduction of Sclerotium roffsii Sacc.. Validamycin can be used as an effective fungicide.

结论］温暖潮湿、偏酸性的环境适合白绢病菌的生长和繁殖，井冈霉素可作为防治白绢病的有效药剂用于田间该病害的控制。

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。
