Fe    音标拼音: [f'e]




Fe
n 1: a heavy ductile magnetic metallic element; is silver-white
in pure form but readily rusts; used in construction and
tools and armament; plays a role in the transport of oxygen
by the blood [synonym: {iron}, {Fe}, {atomic number 26}]

Ion \I"on\ ([imac]"[o^]n), n. [Gr. 'io`n, neut, of 'iw`n, p. pr.
of 'ie`nai to go.]
1. (Elec. Chem.) an atom or goup of atoms (radical) carrying
an electrical charge. It is contrasted with neutral atoms
or molecules, and free radicals. Certain compounds, such
as sodium chloride, are composed of complementary ions in
the solid (crystalline) as well as in solution. Others,
notably acids such as hydrogen chloride, may occur as
neutral molecules in the pure liquid or gas forms, and
ionize almost completely in dilute aqueous solutions. In
solutions (as in water) ions are frequently bound
non-covalently with the molecules of solvent, and in that
case are said to be solvated. According to the
electrolytic dissociation theory, the molecules of
electrolytes are divided into ions by water and other
solvents. An ion consists of one or more atoms and carries
one unit charges of electricity, 3.4 x 10^{-10}
electrostatic units, or a multiple of this. Those which
are positively electrified (hydrogen and the metals) are
called {cations}; negative ions (hydroxyl and acidic atoms
or groups) are called {anions}.

Note: Thus, hydrochloric acid ({HCl}) dissociates, in aqueous
solution, into the hydrogen ion, {H}, and the chlorine
ion, {Cl-}; ferric nitrate, {Fe(NO3)3}, yields the
ferric ion, {Fe}, and nitrate ions, {NO3-}, {NO3-},
{NO3-}. When a solution containing ions is made part of
an electric circuit, the cations move toward the
cathode, the anions toward the anode. This movement is
called migration, and the velocity of it differs for
different kinds of ions. If the electromotive force is
sufficient, electrolysis ensues: cations give up their
charge at the cathode and separate in metallic form or
decompose water, forming hydrogen and alkali;
similarly, at the anode the element of the anion
separates, or the metal of the anode is dissolved, or
decomposition occurs. Aluminum and chlorine are
elements prepared predominantly by such electrolysis,
and depends on dissolving compounds in a solvent where
the element forms ions. Electrolysis is also used in
refining other metals, such as copper and silver. Cf.
{Anion}, {Cation}.
[Webster 1913 Suppl.]

2. One of the small electrified particles into which the
molecules of a gas are broken up under the action of the
electric current, of ultraviolet and certain other rays,
and of high temperatures. To the properties and behavior
of ions the phenomena of the electric discharge through
rarefied gases and many other important effects are
ascribed. At low pressures the negative ions appear to be
electrons; the positive ions, atoms minus an electron. At
ordinary pressures each ion seems to include also a number
of attached molecules. Ions may be formed in a gas in
various ways.
[Webster 1913 Suppl.]


Symbol \Sym"bol\ (s[i^]m"b[o^]l), n. [L. symbolus, symbolum, Gr.
sy`mbolon a sign by which one knows or infers a thing, from
symba`llein to throw or put together, to compare; sy`n with
ba`llein to throw: cf. F. symbole. Cf. {Emblem}, {Parable}.]
1. A visible sign or representation of an idea; anything
which suggests an idea or quality, or another thing, as by
resemblance or by convention; an emblem; a representation;
a type; a figure; as, the lion is the symbol of courage;
the lamb is the symbol of meekness or patience.
[1913 Webster]

A symbol is a sign included in the idea which it
represents, e. g., an actual part chosen to
represent the whole, or a lower form or species used
as the representative of a higher in the same kind.
--Coleridge.
[1913 Webster]

2. (Math.) Any character used to represent a quantity, an
operation, a relation, or an abbreviation.
[1913 Webster]

Note: In crystallography, the symbol of a plane is the
numerical expression which defines its position
relatively to the assumed axes.
[1913 Webster]

3. (Theol.) An abstract or compendium of faith or doctrine; a
creed, or a summary of the articles of religion.
[1913 Webster]

4. [Gr. ? contributions.] That which is thrown into a common
fund; hence, an appointed or accustomed duty. [Obs.]
[1913 Webster]

They do their work in the days of peace . . . and
come to pay their symbol in a war or in a plague.
--Jer. Taylor.
[1913 Webster]

5. Share; allotment. [Obs.]
[1913 Webster]

The persons who are to be judged . . . shall all
appear to receive their symbol. --Jer. Taylor.
[1913 Webster]

6. (Chem.) An abbreviation standing for the name of an
element and consisting of the initial letter of the Latin
or New Latin name, or sometimes of the initial letter with
a following one; as, {C} for carbon, {Na} for sodium
(Natrium), {Fe} for iron (Ferrum), {Sn} for tin (Stannum),
{Sb} for antimony (Stibium), etc. See the list of names
and symbols under {Element}.
[1913 Webster]

Note: In pure and organic chemistry there are symbols not
only for the elements, but also for their grouping in
formulas, radicals, or residues, as evidenced by their
composition, reactions, synthesis, etc. See the diagram
of {Benzene nucleus}, under {Benzene}.
[1913 Webster]

Syn: Emblem; figure; type. See {Emblem}.
[1913 Webster]

  • 请问fe阳面尤其在前两位类型的人格会过度关注他人吗,是为什么呢?
    请问fe阳面尤其在前两位类型的人格会过度关注他人吗,是为什么呢? 不知道是不是因为个人fi三位的缘故,对fe功能不太适应,使用起来非常累,但本身高敏,发现fe阳面似乎非常喜欢关注他人并似乎期待获得某种反应? 生活中两… 显示全部 关注者 1 被浏览

    intp大力发展Fe会有什么后果? intp最弱的功能是fe,外倾情感,如果每天刻意的使用这个功能,比如照顾周围的人,嘘寒问暖,营造让世界充满爱什么的。 会有什么后果? 是会让自己特别累还是… 显示全部 关注者 356 被浏览
  • fe功能在不同位置有怎样的表现? - 知乎
    Fe首位对于Fi的任何状态似乎都是一种包容与呵护的态度,但是Fe三位对Fi则有一种管理的倾向。 Fi过于弱小的话会想要为其注入能量,同样,Fi过于膨胀的话会想要打压和嘲讽。 与其说带来满足,我觉得3rd带来的更多是无法实现愿望的痛苦。
  • 氰铁酸根是否有氧化性,能否氧化Fe? - 知乎
    很认真的说一句,确实是可以氧化的,空口无凭,故我以一道高考题作为依据。 上图是 北京 2018年的理综选择题,图中圈一为什么在Fe被保护的情况下会出现蓝色沉淀呢? 就是因为铁被铁氰酸根给氧化了,所以即使是被保护的情况下,依然被氧化生成了亚铁离子。
  • 如何分辨自己是fi优势还是fe优势? - 知乎
    题主通篇都在表现自己的FE,而且是 英雄般地展示(主导功能)。具体在 理所应当地觉得对大家好优先、面对不符合认知的会想去改变否则会不舒服、难以忍受关系变得不好blabla,太多了我就不念了,我来回答一下你的两个疑惑。 首先,无法判断自己的情感是来自自己还是他人的影响,这是很正常

    图2:通过紫外-可见吸收光谱和Fe K-edge EXAFS,确认在OER过程中形成了分子态FeO₄²⁻物种,其Fe–O键长为1 65 Å,表明其参与反应。 图3:O K-edge XAS与HERFD-XAS进一步证明在OER过程中,溶解态Fe物种与NiFe电极表面的氧中间体发生电子与结构交互,显著促进了O–O键的
  • 为什么有的INTP的fi极其高,fe却是最低的?这种INTP是怎样的?
    理论上,Ti主导直接压制Fe,导致Fe的测试分数低于很多阴面功能,完全是正常现象。 个人不认为MBTI的功能强度要完全按照8功能模型(Beebe模型)的排列顺序或者理论强度才正常。 这里纠正一下Fi=敏感脆弱、感情充沛这种过于简单粗暴的理解。
  • fe功能是不是一种能操纵 蛊惑 欺骗人心的特殊能力? - 知乎
    fe只有加上ni-se才有蛊惑人心的能力,加上se才能会欺骗,也就是nfj stp。 i的话会比较隐晦,而e的话更加明目张胆。 ni才会洞察人心,有预测性,se敢想敢做,行动力强,野兽派。 能够抓住他人的心理,预测对方的想法,才能够操纵他人。
  • 为什么有些fe高的人还很讨厌? - 知乎
    001 fe就是一外倾向功能,和te、se、ne没有区别 都会本能向外扩张,或温和或热忱,但一定具有侵略性,而侵略性本身就会使得一部分人感到不适。 但是,那又咋滴? “讨人喜欢”这是fe的利他用法 我不接受社会对fe的训诫和绑架 “fe使用者必须让人感到如沐春风”
