arbitrary assumption

基本解釋

However, this example makes the arbitrary assumption that an ambiguous time should always be mapped to the time zone's standard time.
但是，這個(gè)范例會(huì)自行假設(shè)，模稜兩可的時(shí)間應(yīng)該要永遠(yuǎn)對(duì)應(yīng)至?xí)r區(qū)的標(biāo)準(zhǔn)時(shí)間。
Furthermore, general performance equivalent analysis methods are put forward based on assumption of arbitrary-distribution of time delay.
在此基礎(chǔ)上，進(jìn)一步把活動(dòng)執(zhí)行時(shí)間擴(kuò)展到任意分布的情況，給出了通用的等價(jià)性能分析方法。

It's an arbitrary assumption, but it does show the relative success of schools in their missions.
