讨论部分写作的人称和语态
在这一节尽可能使用主动语态。慎防罗嗦词组，要简洁。可以使用第一人称描述自己的结果(示例12-5)。现在时和简单的过去时可以用于讨论和结论章节(Pres-ent and simple past tenses may both be correct for resultsdiscussion and conclusions)。
示例12-5  讨论部分写作的人称和语态范例We have also shown that transplantation of cell populationsderived from either a limited number of CDl46+ CFU-Fs or singleCDl46+CFU-Fs resultS in the reestablishment，in the heterotop-ic ossicles,of CDl46+CFU-Fs that can be secondarily passagedand directly assayed．By providing evidence for the ability ofCDl46+stromal cells to function as self-renewing’clonogenicskeletal progenitors，out data outline the long sought anatomicalidentitV of SSCs(“mesenchymal”stem cells)in human BM and aCruCial feature of their phenotype．While our data provide evi-dence for the self-renewal and multipotency of CDl46+ CFUFs,a larger—scale study would be necessary to accurately determinethe actual frequency of in vivo assayable’multipotent,and self-renewing clonogenic progenitors within our population of pheno-type-defined cells．Even though such frequency would appear tobe high based on our data(50％),the relative weight of inherentbiological heterogeneity’versus heterogeneity relative to the spe-cific experimental assay and its constraints(including culture andtransplantation conditions)，remains to be further analyzed．
