高考理綜知識(shí)點(diǎn)總結(jié)歸納物理化學(xué)生物

高考理綜知識(shí)點(diǎn)總結(jié)歸納(物理、化學(xué)、生物)高中理科知識(shí)點(diǎn)總結(jié)高中所有化學(xué)方程式物理學(xué)習(xí)記憶口訣;力的圖示法口訣你要表示力，辦法很簡單。選好比例尺，再畫一段線，長短表大小，箭頭示方向，注意線尾巴，放在作用點(diǎn)。物體受力分析施力不畫畫受力，重力彈力先分析;摩擦力方向要分清，多、漏、錯(cuò)、假須鑒別。牛頓定律的適用步驟畫簡圖、定對(duì)象、明過程、分析力;選坐標(biāo)、作投影、取分量、列方程;求結(jié)果、驗(yàn)單位、代數(shù)據(jù)、作答案。不等臂天平稱量法天平兩臂不相等，待測(cè)物體左右稱;物體質(zhì)量是多少,兩數(shù)積的算術(shù)根。勻速圓周運(yùn)動(dòng)“勻速圓周”并不勻，速度方向變不停，加速度，向圓心，速度平方比半徑。功和能的區(qū)別和聯(lián)系狀態(tài)定，能量定，狀態(tài)能量兩對(duì)應(yīng)，狀態(tài)變化能量變，做功傳熱是過程。關(guān)于密度的計(jì)算密度單位要注明，氣體、溶液必須清，體積換算勿遺忘，立方厘米對(duì)毫升。說明:氣體密度單位常用“克/升”，液體密度單位常用“克/(厘米)3”，體積換算時(shí)，1(厘米)3?1毫升。液體內(nèi)部的壓強(qiáng)公式不管容器粗和細(xì)，哪怕管子斜又曲，液體壓強(qiáng)真稀奇，只看ρ?g和h。注:液體內(nèi)部的壓強(qiáng)公式:P,ρgh。凸透鏡成像規(guī)律實(shí)像倒，虛像正，焦距內(nèi)外分虛實(shí)，二倍焦距物像等，放大縮小要分清。氫原子光譜規(guī)律一二三四五，賴巴帕布普;二三四五六，依次記光譜。電動(dòng)勢(shì)?電壓?電流電源有個(gè)電源力，推動(dòng)電荷到正極，正負(fù)極間有電壓，電路接通電荷移。直流電路等效圖無阻導(dǎo)線縮一點(diǎn)，等勢(shì)點(diǎn)間連成線;斷路無用線撤去，節(jié)點(diǎn)之間依次連;整理圖形標(biāo)準(zhǔn)化，最后還要看一遍。安培定則歌導(dǎo)線周圍的磁力線，用安培定則來判斷。判斷直線用定則一，讓右手直握直導(dǎo)線。電流的方向拇指指，四指指的是磁力線。判斷螺線用定則二，讓右手緊握螺線管。shouldbedealtwithbythepersonnelDepartmentofthecompany.(3)personalinjuryaccidentoccurs,thedirectpunishment500-1000,whoisdirectlyresponsiblefortheaccidentresponsibility,givenoticeofcriticismand50-100economicsanctionsagainstthem.(4)toconcealtheaccident,reportedwithoutunduedelayorfalse,toinformtheadministrativeleadershipofthecriticism,resultinginseriousconsequences,thepursuitofleadership,alongwith500-1000punishment.(5)significantnearmissshouldbeattemptedasthecaseofresponsiblefortheaccidentandconstructionteaminjuriesaccidentpenaltyprovisions,mutatismutandis.Eight,shouldperformintheconstructionstandardsandspecifications,serialnumbera1GB3323-2005steelfusionweldedbuttjoints,weldingengineering-Raylightingandqualityratingof2GB11345-89steelweldsmanualmethodsofultrasonicinspectionandtestingresultsforgrade3GB50236-2002industrialpipeweldingengineeringcodeforconstructionandacceptanceoffieldequipment4HGJ222-92technicalspecificationforweldingofaluminiumanditsalloys5lowtemperaturesteelweldingprocedure6SH3525-2004petrochemicalJB/T4708-2000ofweldingprocedurequalificationforsteelpressurevessels7JB/4709-20008JB4730-2005pressurevesselweldingproceduresofsteelpressurevesselNDT9JB/T4744-2000steelpressurevesselproductsmechanicalpropertiestestofweldedplateII,mechanicalequipmentinstallation電流的方向四指指，N極在拇指指那端。安裝電燈要點(diǎn)火地并排走，地線進(jìn)燈頭，火線進(jìn)開關(guān)，開關(guān)接燈頭。安全用電順口溜電燈離地六尺高，固定安裝最重要。廣播碰到電力線，喇叭怪叫要冒煙。如果有人觸了電，切斷電源莫遲延。電線要是著了火，不能帶電用水潑。初中物理實(shí)驗(yàn)口訣(四則)(一)調(diào)節(jié)天平橫梁平衡物理天平進(jìn)行稱量之前，指針應(yīng)指在刻度中央。若指針偏在標(biāo)尺左側(cè)，將橫梁左端螺絲向左調(diào)，或?qū)M梁右端螺絲向左調(diào)，均能使指針回到標(biāo)尺中央。當(dāng)指針向右偏時(shí)，橫梁螺絲(不論左端或右端的螺絲)應(yīng)向右調(diào)，橫梁螺絲調(diào)節(jié)方向可概括為:左偏左調(diào)，或者左—左，右偏右調(diào)。右—右。托盤天平的指針在橫梁上方，故橫梁螺絲的調(diào)節(jié)方向跟物理天平相反。只要熟記物理天平的口訣，聯(lián)想記憶托盤天平螺絲要反調(diào)，就不會(huì)混淆了。(二)滑動(dòng)變阻器的使用滑動(dòng)變阻器分上下兩層，上層鋼桿和下層電阻絲各有兩個(gè)接線柱，為了變阻，使用時(shí)應(yīng)上下各用一個(gè)接線柱?？珊営洖?一上一下，各用一個(gè)。根據(jù)這一接法，連接實(shí)物時(shí)就不必拘泥于電路圖中滑動(dòng)變阻器的接線方向，從而選擇短距離，避免交叉的布線方式。(三)連接電路的入門方法連接含有并聯(lián)電路的回路時(shí)，可先只連接并聯(lián)導(dǎo)體中的一個(gè)導(dǎo)體，伏特表也暫不接入電路，即首先連接一個(gè)串聯(lián)回路，然后再把并聯(lián)的導(dǎo)體和伏特表接入電路，這種入門的方法叫先串后并。這樣做，對(duì)初學(xué)者能起到化難為易的作用。(四)防止讀錯(cuò)數(shù)據(jù)的一種方法物理量具的刻度方向不盡相同。量筒和溫度計(jì)的上刻度值比下刻度值大，而彈簧和比重計(jì)則相反。再如0.6安培表，每小格刻度值是0.02安培。當(dāng)指針指在沒有標(biāo)值的地方時(shí)，粗心的同學(xué)常會(huì)讀錯(cuò)數(shù)據(jù)。為防止讀錯(cuò)，可以記住這樣一個(gè)口訣:勻中助讀。意思是說，可以先把指針相鄰的兩個(gè)標(biāo)度值中點(diǎn)的值讀出來，再讀指針處的數(shù)據(jù)。高中所有化學(xué)方程式非金屬單質(zhì)(F2，Cl2,O2,S,N2,P,C,Si)1,氧化性:F2+H2===2HFF2+Xe(過量)===XeF22F2(過量)+Xe===XeF4nF2+2M===2MFn(表示大部分金屬)2F2+2H2O===4HF+O22F2+2NaOH===2NaF+OF2+H2OF2+2NaCl===2NaF+Cl2F2+2NaBr===2NaF+Br2F2+2NaI===2NaF+I2F2+Cl2(等體積)===2ClFshouldbedealtwithbythepersonnelDepartmentofthecompany.(3)personalinjuryaccidentoccurs,thedirectpunishment500-1000,whoisdirectlyresponsiblefortheaccidentresponsibility,givenoticeofcriticismand50-100economicsanctionsagainstthem.(4)toconcealtheaccident,reportedwithoutunduedelayorfalse,toinformtheadministrativeleadershipofthecriticism,resultinginseriousconsequences,thepursuitofleadership,alongwith500-1000punishment.(5)significantnearmissshouldbeattemptedasthecaseofresponsiblefortheaccidentandconstructionteaminjuriesaccidentpenaltyprovisions,mutatismutandis.Eight,shouldperformintheconstructionstandardsandspecifications,serialnumbera1GB3323-2005steelfusionweldedbuttjoints,weldingengineering-Raylightingandqualityratingof2GB11345-89steelweldsmanualmethodsofultrasonicinspectionandtestingresultsforgrade3GB50236-2002industrialpipeweldingengineeringcodeforconstructionandacceptanceoffieldequipment4HGJ222-92technicalspecificationforweldingofaluminiumanditsalloys5lowtemperaturesteelweldingprocedure6SH3525-2004petrochemicalJB/T4708-2000ofweldingprocedurequalificationforsteelpressurevessels7JB/4709-20008JB4730-2005pressurevesselweldingproceduresofsteelpressurevesselNDT9JB/T4744-2000steelpressurevesselproductsmechanicalpropertiestestofweldedplateII,mechanicalequipmentinstallation3F2(過量)+Cl2===2ClF37F2(過量)+I2===2IF7Cl2+H2===2HCl3C

ì)胞膜、液泡膜及兩層膜之間的細(xì)胞質(zhì)。它與成熟植物細(xì)胞的原生質(zhì)相比，缺少了細(xì)胞液和細(xì)胞核兩部分。九、赤道板與細(xì)胞板赤道板:細(xì)胞中央的一個(gè)平面，這個(gè)平面與有絲分裂中紡錘體的中軸相垂直，類似于地球赤道的位置。細(xì)胞板:植物細(xì)胞有絲分裂末期在赤道板的位置出現(xiàn)的一層結(jié)構(gòu)，隨細(xì)胞分裂的進(jìn)行，它由細(xì)胞中央向四周擴(kuò)展，逐漸形成新的細(xì)胞壁。十、半透膜與選擇透過性膜半透膜:是指某些物質(zhì)可以透過，而另一些物質(zhì)不能透過的多孔性薄膜(如動(dòng)物的膀胱膜，腸衣、玻璃紙等)。它往往只能讓小分子物質(zhì)透過，而大分子物質(zhì)則不能透過，透過的依據(jù)是分子或離子的大小。不具有選擇性，不是生物膜。選擇透過性膜:是指水分子能自由通過，細(xì)胞要選擇吸收的離子和小分子也可以通過，而其他的離子、小分子和大分子則不能通過的生物膜。如細(xì)胞膜、液泡膜和原生質(zhì)層。這些膜具有選擇性的根本原因在于膜上具有運(yùn)載不同物質(zhì)的載體。當(dāng)細(xì)胞死亡后，膜的選擇透過性消失，說明它具有生物活性，所以說選擇透過性膜是功能完善的一類半透膜。十一、載體與運(yùn)載體載體:指某些能傳遞能量或運(yùn)載其他物質(zhì)的物質(zhì)，如細(xì)胞膜上的載體。運(yùn)載體:在遺傳工程中，用于把外源基因運(yùn)入受體細(xì)胞的運(yùn)輸工具，它必須具備的條件是:能夠在宿主細(xì)胞中復(fù)制并穩(wěn)定地保存;具有多個(gè)限制酶切點(diǎn)，以便與外源基因連接;具有某些標(biāo)記基因，便于進(jìn)行篩選。常用的運(yùn)載體有質(zhì)粒、噬菌體、動(dòng)植物病毒等。十二、糖被與珠被shouldbedealtwithbythepersonnelDepartmentofthecompany.(3)personalinjuryaccidentoccurs,thedirectpunishment500-1000,whoisdirectlyresponsiblefortheaccidentresponsibility,givenoticeofcriticismand50-100ec
