SCI論文的材料和方法部分是SCI作者最容易復制和重寫的部分。它也可以說是整個寫作過程中最低的部分。然而，為了避免因大量摘錄而導致的高重復率，我們通?？梢苑e累更多相關(guān)的單詞，并根據(jù)以前的文章進行重寫。

?

一般來說，只要連續(xù)七個字不重復，查重的總重復率不超過20%，單篇文章的重復率不超過5%。接下來，編輯對SCI論文的材料和方法中的高頻詞和短語進行了總結(jié)，希望對大家有幫助。

?

常用動詞

?

實驗中常用動詞：

extracted, dissected, homogenized, separated, transfer, purchased, dissolved, chronically exposed, sacrificed, housed, deprived of, handled, placed, recorded, divided into, adopted, determine, performed, loaded, downloaded, diluted, performed, obtained, amplified, fused with, cloned into, employed, construct, described, allows, governs, implemented, split into, carried out, harboring, generate, incorporate,

?

兩物之間關(guān)系：

compare to/with，depend on, based on, relies on, (strongly) associated with/to, related to,

?

“認為，說明” 的N種描述方式：

assume, states, indicated, suggested, demonstrated, considered as

?

分配描述：

respectively, randomly assigned, simultaneously, predominantly, mutually exclusive patterns.

?

動物處置：

anesthetized, decapitated

?

實驗過程連接詞

?

介紹實驗過程的時候，肯定免不了對實驗順序的介紹。實驗有先后，關(guān)于順序的連接詞：

Initially, additionally, in addition, moreover, furthermore, hereafter, therefore, consistently, In practice, to this end, subsequently, briefly, then, finally, accordingly, recently, nevertheless, however, indeed,

有時候，在實驗方法的過程中，作者還會用實驗目的來進行段落之間的連接。讓實驗過程更有層次性。有關(guān)目的連接的表達方法：

To address the genetic burdens, to better understand the association, to test for the presence of sample or data, testing and verification of the presence, to overcome this limitation.

?

數(shù)據(jù)處理相關(guān)

?

材料與方法中，經(jīng)常對實驗對象(病人、動物等)的實驗數(shù)據(jù)進行評估，非常高頻。“評估” 的常見表示方法有：

obtained, estimated, evaluated, assessed, measured, examined, investigate, explore, test the sensitivity and specificity of variables, identify, quantify, is characterized by。

實驗中常常涉及到對數(shù)據(jù)處理的部分。那文章中的數(shù)據(jù)可以有哪些被“處理”的方法呢：

deposited, classified, downloaded, revised, included, removed, normalized, combined, subdivided into, calculated, cross-check, summarized, originated from, described, available, detectable, define, scored, determined, generated with, using, applied with, categorize ... into ..., model, imputed, presented, determined, filtered, processed, background-corrected, normalized to internal controls, quality control, Images were captured, Freshly sorted XX cells, carried out.

?

數(shù)據(jù)描述：

High confidence, remarkably high, freely available，

?

樣本描述：

In all examined samples

?

實驗層次描述，生物學中常常分為四個層次：

in vivo是指的活體內(nèi)，也就是動物模型。

in vitro是指的離體、體外的意思

ex vivo, 指的是活體取材，一部分動物實驗完成后取器官，或者指的是體外培養(yǎng)細胞體內(nèi)的回輸實驗。

in silico，指的是生物分析實驗，用芯片、高通量測序等方法進行生信分析等實驗。

?

實驗倫理相關(guān)

?

患者知情同意書：

participants provided informed consent，Written informed consent

?

納入患者：patient recruitment

?

倫理委員會：

ethics committee/institutional review board (IRB)，Ethics board approval ，Institute Animal Ethics Committee.

?

相關(guān)法律法規(guī)：

relevant guidelines and regulations，

?

根據(jù)前人研究方法總結(jié)

?

為了簡化對實驗方法的描述，精煉文章文字。根據(jù)之前文獻描述的描述方法/研究：

as previously described, in accordance with, complied with, from previously published studies, deciphered using the framework developed by previously, using previously described expression profiles, for some of the previously published samples, Previously published data in peer-review journals, Following previous work.

?

統(tǒng)計方法描述

?

在材料與方法的最后一部分，往往是對統(tǒng)計方法的描述。常見統(tǒng)計方法 (statistical tests) 的描述：

t-test, χ2 tests, cox regression, Kaplan-Meier method, the receiver operating characteristic (ROC) curves, one-way ANOVAs, Bonferroni's multiple comparisons test, Mann-Whitney U tests, linear regression tests, Cox regression, variance (ANOVA) for quantitative features, Wilcoxon’s rank-sum test

?
