seasonal energy

The factors affecting the Seasonal Energy Efficiency Ratio ( SEER ) have been investigated.

探讨房间 空调器 的季节性能特性及提高季节能效比的有效途径.

For the full-year-operation PRW, seasonal thermal energy storage plays an important role in the heat source of the heat pump.

对于冬夏均运行的抽灌同井，季节性蓄能是热泵热源的重要组成部分。

The energy efficiency indexes contain seasonal system energy efficiency ratio, primary energy ratio, energy saving rate, saved amount of standard coal. The evaluation of economic benefit is by the method of payback period according to the initial cost and operating expense.

节能效益通过季节系统能效比、能源利用系数、节能率、可替代标煤量的指标来评价；经济效益通过计算初投资和年运营费用，采用投资回收年限法进行经济评价。

The energy content and their seasonal variations of Arachnida in arid environment were studied.

研究干旱地区蛛形纲动物的含能值变动规律.

For PRW, the seasonal thermal energy storage ( STES) alleviated the dependency on aquifer for heat source or sink, and made aquifer as a carrier for heat storage.

抽灌同井运行时的季节性储能很大程度地减轻了对含水层作为热源（汇）的依赖，而让其作为一种蓄热的载体。

The energy content of different body regions in Arachnida also exhibited significantly seasonal variations, with the maximal values in autumn ( the mean was 22.98 J/ mg AFDW) and minimal in spring ( the mean was 19.80 J/ mg AFDW).

不同体区含能值同样也表现出季节变动，最高为秋季（平均值22.98J/mg无灰干重），最低为春季（平均值19.80J/mg无灰干重）。
