lcholine in a reversible fashion. It is the plex of receptor bined with acetylcholine which brings about a biophysical reaction, resulting in the response from the receptive cell. Two major types of acetylcholine receptors exist in the membranes of cells. The type in skeletal muscle is known as ‘nicotinic’。 the glorification of the act of painting itself as a means of visual munication。 零假設(shè) Ho實(shí)際上是正確的,卻被否定了。 27.點(diǎn)估計(jì) 所謂點(diǎn)估計(jì),就是根據(jù)樣本數(shù)據(jù)算出一個(gè)單一的估計(jì)值,用它來(lái)估計(jì)總體的參數(shù)值。 已知一總體分布,可求得它的特征值。早期的統(tǒng)計(jì)都是描述統(tǒng)計(jì)。 電大社會(huì)統(tǒng)計(jì)學(xué)名詞解釋資料小抄 1.社會(huì)統(tǒng)計(jì)學(xué) 社會(huì)統(tǒng)計(jì)學(xué)是運(yùn)用統(tǒng)計(jì)學(xué)的一般原理,對(duì)社會(huì)各種靜態(tài)結(jié)構(gòu)和動(dòng)態(tài)趨勢(shì)進(jìn)行定量描述或推斷的一種專門(mén)方法與技術(shù)。 8.推論性統(tǒng)計(jì) 推論性統(tǒng)計(jì),主要是依據(jù)概率論,研究如何依據(jù)有限資料對(duì)總體性 質(zhì)作推斷,從而使統(tǒng)計(jì)的功能大為擴(kuò)充。根據(jù)總體分布計(jì)算的特征值,即根據(jù)總體各個(gè)單位標(biāo)志值計(jì)算的統(tǒng)計(jì)指標(biāo),在推論統(tǒng)計(jì)中稱為總體參數(shù)。 28.區(qū)間估計(jì) 所謂區(qū) 間估計(jì),就是計(jì)算抽樣平均誤差,指出估計(jì)的可信程度,進(jìn)而在點(diǎn)估計(jì)的基礎(chǔ)上,確定總體參數(shù)的所在范圍或區(qū)間。 零假設(shè) Ho實(shí)際上是錯(cuò)誤的,卻沒(méi)有被否定。 and the attempt to transfer pure emotion directly onto the canvas. The movement had an inestimable influence on the many varieties of work that followed it, especially in the way its proponents used color and materials. Its essential energy transmitted an enduring excitement to the American art scene. 。 an enzyme (cholinesterase) breaks the transmitter down into choline and an acetate ion. The choline is then available for reuptake into the nerve terminal. These same principles apply to cholinergic transmission at sites other than neuromuscular junctions, although the structure of the synapses differs. In the autonomic nervous system these include nervetonerve synapses at the relay stations (ganglia) in both the sympathetic and the parasympathetic divisions, and the endings of parasympathetic nerve fibres on nonvoluntary (smooth) muscle, the heart, and glandular cells。 。 檢驗(yàn)統(tǒng)計(jì)量是關(guān)于樣本的一個(gè)綜合指標(biāo),但與參數(shù)估計(jì)中討論的統(tǒng)計(jì)量有所不同,它不用作估測(cè),而只用作檢驗(yàn)。 9.樣本和(或)樣本總體 樣本或樣本總體,是通過(guò)抽樣得到的用以推斷總體特征的那個(gè)“部分”。 2.國(guó)勢(shì)學(xué)派 產(chǎn)生于德國(guó),其創(chuàng)始人為康令和阿亨瓦爾。大量觀察法是統(tǒng)計(jì)調(diào)查階段的重要方法 6.大數(shù)規(guī)律 大數(shù)規(guī)律是隨機(jī)現(xiàn)象出現(xiàn)的基本規(guī)律,它的一般意義是:觀察過(guò)程中每次取得的結(jié)果可能不同(因?yàn)榫哂信既恍裕罅恐貜?fù)觀察結(jié)果的平均值卻幾乎接近某個(gè)確定的數(shù)值。 18.平均指標(biāo): 就是表明同質(zhì)總體在一定條件下某一數(shù)量標(biāo)志所達(dá)到的一般水平。設(shè) 2?

These terms are used because nicotine mimics the action of acetylcholine at nicotinic receptors, whereas muscarine, an alkaloid from the mushroom Amanita muscaria, mimics the
