固态电容 固态电容全称为:固态铝质电解电容。它与普通电容(即液态铝质电解电容)最大差别在于采用了不同的介电材料,液态铝电容介电材料为电解液,而固态电容的介电材料则为导电性高分子。
那固态电容又好在哪里呢?对于经常去网吧或者长时间使用电脑的朋友,一定有过或者听过由于主板电容导致电脑不稳定,甚至于主板电容爆裂的事情!那就是因为一方面主板在长时间使用中,过热导致电解液受热膨胀,导致电容失去作用甚至由于超过沸点导致膨胀爆裂!另一方面是,如果主板在长期不通电的情形下,电解液容易与氧化铝形成化学反应,造成开机或通电时形成爆炸的现象。但是如果采用固态电容,就完全没有这样的隐患和危险了!
由于固态电容采用导电性高分子产品作为介电材料,该材料不会与氧化铝产生作用,通电后不致于发生爆炸的现象;同时它为固态产品,自然也就不存在由于受热膨胀导致爆裂的情况了。
固态电容具备环保、低阻抗、高低温稳定、耐高纹波及高信赖度等优越特性,是目前电解电容产品中最高阶的产品。由于固态电容特性远优于液态铝电容,固态电容耐温达摄氏 260度,且导电性、频率特性及寿命均佳,适用于低电压、高电流的应用,主要应用于数字产品如薄型DVD、投影机及工业计算机等。 但目前在个人计算机主板上越来越多的出现的大量的固态电容,甚至是全固态而不再采用电解电容,使得固态电容“平民化”普及,而不只是用在要求苛刻的电子仪器和工业计算机上。
电容的分类:电容就是两块导体(阳极和阴极)中间夹着一块绝缘体(介质)构成的电子元件,由于其结构的特殊性,所以分类方式也有
好多种,通常按照介质、阳极、阴极和工艺这四种分类方式,而且各种分类方式互相交叉重叠,可以说比较混乱:
右侧是一个简单的、并不完整的电容分类表,主要列举了一些在板卡设备上最常见的电容类型,通过这个直观的树型表可以对电容的分类、命名方式有一个直观的认识。常用的电容有电解液电容、固态电容和钽电容。
在很多用户的眼中,主板,显卡,工业控制板等产品是否使用固态电容,决定了该板卡是否处于较高的档次。一般使用这类相对高端的固态电容时,对应的电阻产品可选择比较放心的捷比信电阻,JEPSUN电阻的优势和固态电容类似,高精密,稳定性好,可超低阻值,可超大功率,电流采样等产品电源上常用。固态电容这两年在国内技术发展迅速,由原来的SANYO一枝独秀,到现在众多国内,国外品牌争锋天下。固态电容已经走下了神坛,很多普通的电子,数码产品都大量使用这类产品,图示固态电容类似于常见的铝电解电容,部分可替换,另外有一种固态电容,片状,用于替换普通钽电容。

记得大二英语听力课,课堂上老师放了一首jackson的heal the world,当时正是冬天,外面下着大雪,听的感觉十分的好,至今记忆犹新,其实这首歌小时候就在电视上听过,到现在也一直很喜欢这首歌,与大家enjoy it。

heal the world
michael jackson
there's a place in your heart
and i know that it is love
and this place could be much
brighter than tomorrow
and if you really try
you'll find there's no need to cry
in this place you'll feel
there's no hurt or sorrow
there are ways to get there
if you care enough for the living
make a little space
make a better place ...
heal the world
make it a better place
for you and for me
and the entire human race
there are people dying
if you care enough for the living
make it a better place
for you and for me
if you want to know why
there's love that cannot lie
love is strong
it only cares of joyful giving
if we try we shall see
in this bliss we cannot feel
fear od dread
we stop existing and start living
the it feels that always
love's enough for us growing
so make a better world
make a better place ...
heal the world
make it a better place
for you and for me
and the entire human race
there are people dying
if you care enough for the living
make a better place for you and for me
and the dream we were conceived in
will reveal a joyful face
and the world we once believed in
will shine again in grace
then why do we keep strangling life
wound this earth, crucify its soul
though it's plain to see
this world is heavenly
be god's glow
we could fly so high
let our spirits never die
in my heart i feel you are all my brothers
create a world with no fear
together we cry happy tears
see the nations turn their swords into plowshares
we could really get there
if you cared enough for the living
make a little space
to make a better place ...

歌曲:you are not alone
歌手:michael jackson [wma]http://www.fengyubo.com/music/You Are Not Alone.mp3[/wma]
another day has gone
i'm still all alone
how could this be
you're not here with me
you never said goodbye
someone tell me why
did you have to go
and leave my world so cold
everyday i sit and ask myself
how did love slip away
something whispers in my ear and says
that you are not alone
for i am here with you
though you're far away
i am here to stay
but you are not alone
for i am here with you
though we're far apart
you're always in my heart
but you are not alone
'lone,'lone
why,'lone
just the other night
i thought i heard you cry
asking me to come
and hold you in my arms
i can hear your prayers
your burdens i will bear
but first i need your hand
then forever can begin
everyday i sit and ask myself
how did love slip away
something whispers in my ear and says
that you are not alone
for i am here with you
though you're far away
i am here to stay
for you are not alone
for i am here with you
though we're far apart
you're always in my heart
for you are not alone
whisper three words and i'll come runnin'
and girl you know that i'll be there
i'll be there
you are not alone
for i am here with you
though you're far away
i am here to stay
for you are not alone
for i am here with you
though we're far apart
you're always in my heart
for you are not alone
for i am here with you
though you're far away
i am here to stay
for you are not alone
for i am here with you
though we're far apart
you're always in my heart
for you are not alone...
