| Zero initial conditions | 零初始條件 |
The assumption normally made in control engineering that up to a start time defined as t = 0, all variables have zero value. 在控制工程中通常作出的假設，即在定義為t=0的開始時間內(nèi)，所有變量均為零值。 |
| Zero time | 零時 |
The time when the given loading or constraint conditions are initially obtained in creep or stressrelaxation tests, respectively. 分別在蠕變或應力松弛試驗中初始獲得給定載荷或約束條件的時間。 |
| Zero-gravity | 零重力 |
The situation in which there is no force of gravity (i.e. weightlessness). 沒有重力的情況（即失重）。 |
| Zirconia-toughened alumina composites | 氧化鋯增韌氧化鋁復合材料 |
(ZTA composites) Ceramic composites based on aluminium oxide to which zirconium oxide is added, resulting in improved fracture toughness. （ZTA復合材料）基于氧化鋁的陶瓷復合材料，其中添加了氧化鋯，從而提高了斷裂韌性。 |
| Zone melting (zone refining) | 區(qū)域熔煉（區(qū)域精煉） |
A process of purification of materials in which a narrow molten zone is moved along the length of the material, resulting in impurities being segregated at one end. 一種凈化材料的過程，其中一個狹窄的熔融區(qū)沿材料長度移動，導致雜質在一端分離。 |
