分析利用向量的模的运算法则求解即可．
解答解：向量$\overrightarrow{a，}\overrightarrow{b}$满足$|\overrightarrow{a}|$=$\sqrt{3}$，$|\overrightarrow{b}|$=4，$\overrightarrow{a}$与$\overrightarrow{b}$的夹角为150°，
则|2$\overrightarrow{a}$-$\overrightarrow{b}$|=$\sqrt{4{\overrightarrow{a}}^{2}-4\overrightarrow{a}•\overrightarrow{b}+{\overrightarrow{b}}^{2}}$=$\sqrt{12-16\sqrt{3}×（-\frac{\sqrt{3}}{2}）+16}$=$2\sqrt{13}$．
故答案为：$2\sqrt{13}$．
点评本题考查平面向量数量积的运算，考查计算能力．
