GB/Z 22559.1-2008齒輪.熱功率.第1部分:油池溫度在95℃時齒輪裝置的熱平衡計算

GB/Z 22559的本部分利用分析熱平衡的模型，為用礦物油潤滑的單位或多級齒輪裝置提供了一種計算熱功率的方法。計算是根據(jù)以下標準條件進行的，高的環(huán)境溫度不高于25℃，在大的房間內(nèi)，油池的高溫度不高于95℃；對于其他條件，要進行修正。

YBB 0036-2004玻璃顆粒在98℃耐水性測定法

本法適用于各類藥用玻璃耐水性的滴定法測定和分級。本法是一種材質(zhì)試驗法。將粒徑為300μm～500μm的玻璃顆粒2g，在98℃試驗用水中浸泡60min。通過滴定浸蝕液來測量玻璃顆粒受水浸蝕的程度并分級。

ITU-R REPORT M.2121-2007在960-1164 MHz頻段的航空移動通信系統(tǒng)(AM(R)S)的共享研究導則

Current aviation communication bands are severely congested and further pressured by the introduction of new aviation applications and security requirements. In addition, recent experience has shown that evolving technology for navigation and surveillance may necessitate allocations that are more encompassing than simply aeronautical radionavigation service (ARNS).
