Although expenditures from an imprest petty cash funds are made in currency and coins,the fund is established or increased by writing a check against the general bank account.
句中的by writing为什么要用ing形式啊?是什么用法啊?什么意思啊?

by是“通过...方式”的意思
by是介词,后面的动词要用ing形式。

by 后面要接名词,writing是动名词。意思是通过写一张支票。

类似的例子:
I got good grades by hard-working.
I keep good health by doing exercises.
