style="font-family: 宋体, SimSun; background-color: #F2DCDB;"><strong>A 上海交通大学教授、科学网博主乔中东:</strong></span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 宋体, SimSun;">对于这样的问题要根据情况而定,不能因为别人有了相同的研究结果,就把自己已经做了很久的研究放弃了!现在有很多研究,都是在查阅文献的基础上进行的查缺补漏的工作,也有很多课题组进行着非常原创的工作。尽管是原创的工作,世界这么大,科学家这么多,就很有可能有其他的科学家和你想到一起去了,进行了几乎相同的研究。谁是第一就看谁手快了!</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 宋体, SimSun;">我有个学生博士毕业以后去了美国,在一次小范围的学术会议上,他汇报了自己的研究进展。过了不久,那天参加会议的一个同行就根据我这个学生的idea发表了论文。我的这个学生非常沮丧。好在他手头有很多别人不知道的新的研究结果,他迅速扩大了自己的研究,在那个同行发表的论文基础上,创新性地提出了自己的新观点,新见解!虽然我的这个学生没有成为第一,但是他丰富了人们对事情的认识。他的论文比那个同行更引入关注。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 宋体, SimSun;">我们实验室是研究吸烟对男性生殖影响的。我的一个博士研究生在写论文的时候,突然发现有同行已经发表了相同的研究结果。这对我们的影响太大了。假如我的这个博士研究生的研究结果不能发表的话,他再重新开始新的研究的话,他可能就会面临逾期不能毕业,不能获得博士学位的问题了。我们认真读了同行的文章,发现:他提出的见解不一定正确,因为吸烟或者尼古丁处理小鼠后,小鼠的间质细胞没有发生凋亡,而是发生了自噬。因此,我们就把一篇描述性的文章改成了批评性的文章。对同行的观点进行了反驳。这样我们也没有增加新的研究,很顺利地将文章发表了,我的这个博士研究生也顺利拿到了博士学位。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 宋体, SimSun;">当然,假如你的研究刚刚开始,更改研究方向还有足够的时间的话,是可以及时转向的。尽管这样,我还是觉得,不要轻言放弃。因为每个人的研究终归不是简单的重复,总会有一些不一样的结果。所以通过不同的角度去认识事物,观察自然规律,一定会得出科学的结论的,丰富我们对自然界的认识的。</span></p><p style="line-height: 2em; text-indent: 2em;

style="font-family: 宋体, SimSun;">我还没有碰到过同行完全想在我们前面、堵得我们无路可走的情况。 </span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 宋体, SimSun;">其实,无论是自己的团队与同行之间,还是团队内部成员之间,都可以有你追我赶、“各庄的地道各有各的高招”的情形,这样就推动着研究领域的不断进步。 </span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 宋体, SimSun;">例如,我们团队一位成员(博士生)曾经先做了一个三参数负指数模型,寻找某年出版的论文集合在出版后t年的时间窗口中从未受到任何引用的论文占论文总量比例的变化规律。拟合公式中,参数A表示随着引用时间窗口的变宽,论文零被引率下降的幅度;变量S表示老化率或衰减系数,又可称为“睡眠” (直到首次引用将其激活之前的状态)系数,表示随着时间的流逝,零被引论文仍处于未被引 状态的概率。那位博士生毕业离开后,另一位成员另辟蹊径,用一个两参数模型来反映科技期刊论文首次被引的幂律分布,然后用1减去两参数模型得出的论文首次被引概率值,就得出零被引科技期刊论文占论文总量比例的概率值。后一模型的拟合效果总体上优于前一模型,还减少了一个参数。</span></p><p style="line-height: 2em; text-indent: 2em;"><span
