wave interference | 波（的）干涉
| The PHENOMENON which results when WAVES of the same or nearly the same FREQUENCY are superposed. It is characterized by a spatial or tempo... more | 频率相同或相近的波叠加后产生的一种现象。与单一的叠加波不同，其振幅具有特殊的空间或时间分布。 |
|
|
wave length | 波长
| The distance between corresponding points of two successive PERIODIC WAVES in the direction of propagation, for which the OSCILLATION has th... more | 传播方向上，振动相位相同的两个连续的周期波相应点间的距离。测量单位为米。亦可写为一个词。 |
|
|
wavemeter | 波浪计，波长表
| An instrument for measuring WAVES. One used for ocean waves usually measures HEIGHT and PERIOD; one used for ELECTROMAGNETIC or SOUND WAVES ... more | 测量波浪的装置。用于测量海浪时，通常是测定浪高和周期；用于测量电磁波或声波时，通常测量其波长。亦可分开写成两个单词。 |
|
|
wave of translation | 平移波，推进波
| A WAVE in which the individual particles of the medium are shifted in the direction of wave travel, as ocean waves in shoal waters. Disting... more | 介质中每个质点沿波的传播方向移动的一种波，如浅滩中的波浪。与振荡波有区别。 |
|
|
wave period | 波浪周期
| The time, in SECONDS, required for a WAVE CREST to traverse a distance equal to one WAVE LENGTH. | 波峰行走一个波长距离所需的时间（单位为秒）。 |
|
|
wave refraction | 波浪折射
| See REFRACTION OF WATER WAVES. | 在浅水区，与等深线成一定角度运动的波浪方向改变的过程。这是因为在浅水区前进的那部分波浪，比深水区同时前进的波浪速度要慢，引起前者波峰折向，变为与等深线方向一致。亦称波折射。由于潮流引起的波峰弯曲。 |
|
|
wave spectrum | 波谱，波列
| In ocean wave studies, a graph showing the distribution of WAVE HEIGHTS with respect to FREQUENCY in a wave record. | 海浪研究中，波高随频率变化的分布图。 |
|
|
wave train | 波串（列），同向波族
| A series of WAVES moving in the same direction. See WAVE: SOLITARY. | 在同一方向上移动的一系列波。 |
|
|
wave trough | 波谷
| See TROUGH. | 海底长洼地，通常比海沟宽并且浅。某大气层区，该区内的气压比同层周围的气压低。在气候图上，用近似V形的平行等压线或等高线表示低压槽，该V形凹面朝向低压区。两连续波峰之间的最低部分。 |
|
|
wave velocity | 波速率，波速
| The SPEED at which the individual wave form advances. A vector quantity that specifies the SPEED and direction with which a SOUND WAVE trav... more | 单个波形的行进速率。
定义声波在介质中传播方向和速度的一种矢量。 |
|
|
waxing moon | 盈月，上弦月
| See PHASES OF THE MOON. | 在太阳月各个阶段中，月亮的不同表现。月相周期从新月开始，或从合时月亮的变化开始。在其前半部分时间中，直至满月在合处出现为止，下弦月亮面逐渐增大，而其后在后半部分时间里，下弦月亮面逐渐变小。第一阶段发生在上弦月位于东方照时，最后一个阶段发生在下弦月位于西方照时。从后一阶段到朔，再从... more |

way | 航行
| The motion of a vessel through the water. | 船穿过水的运动。 |
|
|
weather | 上风的，逆风的 | adj.). Of or pertaining to the direction from which the WIND is blowing, as opposed to LEE. | 与风向相反的，与下风（Lee）反义。 |
|
|
weather | 上风的，逆风的 | State of the ATMOSPHERE at a given time, as defined by the various meteorological elements. | 与风向相反的，与下风（Lee）反义。 |
|
|
weather analysis | 天气分析
| Operation of studying the general state of the ATMOSPHERE over a region, with respect to SYNOPTIC CHARTS. Also called synoptic analysis. | 对于天气图而言，研究一个区域大气的整体状况。亦称synoptic analysis。 |
|
|
weather buoy | 气象浮标
| An Ocean Data Acquisition System (ODAS) used for collecting oceanographic or meteorological information. ODAS buoys are up to 40 feet in dia... more | 一种海洋数据采集系统（ODAS），用于采集海洋信息或气象信息。ODAS浮标直径可达40英尺。 |
|
|
weather forecast | 天气预报
| Statement of the expected meteorological conditions for a specified period, and for specified area or portion of air space. | 在指定时间内，且指定区域空域部分的预期气象情况。 |
|
|
weather chart (or map) | 天气图
| See CHART. | 用数字、符号或等值线表示气象条件和要素的地图。亦称synoptic chart (or map)。 |
|
|
weathered ice | 风化冰
| Hummocked POLAR ICE subjected to weathering which has given the HUMMOCKS and PRESSURE RIDGES a rounded form. If the weathering continues, t... more | 风化形成的冰丘及压力冰脊。如果继续风化，冰表面会变得越来越平坦。 |
