Zhongguo cuzhong zazhi, 2022 目的 比较SWI相位图病灶本身信号强度（传统直观）法与病灶周围征象即极晕（间接）法对单纯出血或单纯钙化的诊断效能。 方法 本研究纳入以随访CT为“金标准”（单次病灶CT或复查CT值变化）的单纯钙化灶和单纯出血灶。针对每个病灶分别采用SWI相位图病灶本身信号强度（传统直观）法和病灶周围极晕（间接）法评估。SWI相位图全部转换为右手图后再进行评估。SWI相位图病灶本身信号强度（传统直观）法评估标准：病灶本身呈低、高信号分别代表出血及钙化。病灶周围极晕（间接）法评估标准：低信号两极征或高信号反晕征 ...

On solutions to the diuphantion equation (关于丢番图方程的解)
Zhejiang Daxue xuebao. Lixue ban, 2005 丢番图方程是一种很重要的且引人注目的指数丢番图方程.用初等方法证明了，若f(x) = (g(x))2+a，a∈Q，这里g(x)是系数的最大分母为k的有理系数多项式，2r|| k，则该方程在2n时的解(x，y，n)必满足，从而给出了该类方程的解的上界，改进了参考文献中的一些结果.

PRESERVATION AND REVITALISATION OF THE ENDANGERED GĨKŨYŨ FLUTE
African Music : Journal of the International Library of African Music, 2016 Based on observations, interviews, and recordings collected in Kenya in May-June 2015, this article presents a summary of the search for a nearly “extinct†musical instrument and the need for advocacy research. The mũtũrĩrũ, originally an oblique bark flute of the Agĩkũyũ of Kenya, is also made from more durable bamboo and plastic.
