您要查找的是不是:
- energy per transmitted symbol 每-传送符号的能量
- Hotter objects also radiate more energy per unit area than cooler objects. 较高温的物体每单位面积所辐射的能量亦较多。
- However, CARI requires invoking the IFFT process several times per transmitted OFDM symbol.The proposed method requires only two IFFT operations by using time domain modification. 此提出的技术用在较少的候选数目时会比较优良,不但可以简化系统而且也不会牺牲掉错误率,这些结果最后都会用电脑把它模拟出来。
- The greatest amount of nuclear binding energy per nucleon occurs for nuclei in the vicinity of iron. 按每个核子计,最大的核结合能量出现在铁附近的核中。
- Perhaps a key adaptive advantage of the angiosperm is their ability to construct wood with much less expenditure of energy per unit weight. 也许被子植物适应优势的秘诀就在于它们有能力形成每单位重量的木材可支付少得多的能。
- It is frequently referred to as "pressure head" when expressed in terms of energy per unit weight of water. 当以单位水重的能量来表达时,经常看作为“压头”。
- Two new quantities defined by ICRU, energy deposit and converted energy per unit masscema are described in this paper. 本文介绍了 ICRU定义的两个新量 ,沉积能 ( energy deposit)和比转换能 ( cema)。
- Energy per ton of ethylene chloride can be down by 1626 MJ after revamping of di-rect chlorination units. 对直接氯化单元进行改造,生产每吨二氯乙烷可节能1626MJ。
- As the natural gas as a clean energy per 1 cubic meter of natural gas can be made about 4 kWh. 天然气发电作为国内清洁能源的一种,每1立方米天然气大约可发4度电。
- They provide 9 kcal of energy per gram which is approximately double the energy provided by proteins or carbohydrates. 每克油脂可提供9千卡热量,这约为同量蛋白质或碳水化合物所提供的热量的两倍。
- Then the estimated carrier signal is multiplied with the successive received signal, respectively, to demodulate the successive transmitted symbols. 然后将估计的载波信号和后续接收信号相乘,解调后续发送符号。
- In the first place, the fractional decrease in neutron energy per collision is, on the average, greatest for light nuclei. 第一,平均来说原子核愈轻,每次碰撞后中子的能量损失分额就愈大。
- The tickler about energy utilization of China was analyzed, such as lack of energy per capita, low quality of energy utilization, increasing aggravation of environment questions. 摘要分析了我国能源利用面临的难题,我国人均能源匮乏,能源利用质量低下,由此引发的环境问题日益加剧。
- In the first place, the fractional decrease in neutron energy per collision is, on the average , greatest for light nuclei. 第一,平均来说原子核愈轻,每次碰撞后中子的能量损失分额就愈大。
- China, the most populous country on earth, is estimated to use two to three times more energy per square metre of its buildings than most advanced economies. 据估计,中国(界上人口最多的国家)筑物每平米能源消耗量是多数发达国家的2至3倍。
- Coal contains less energy per unit of weight than natural gas or oil it is difficult to transport, and it is associated with a host of environmental issues, among them acid rain. 煤的单位能量含量低于石油和天然气,而且会导致包括酸雨在内的一系列环境问题。
- Potatoes can produce more energy per unit area per day than any other crop, and it is possible (though tedious) to subsist on a diet of spuds and very little else. 以每天每单位面积来计算,它所产生的能量比任何其它粮食作物都要多。而且只要有了它,人类便几乎不需要其它食物来维系其生存了(虽然这样的食谱过于单调乏味)。
- For example, a 20 hp induction motor (230vac line to line, 4 pole, wye connected) contains about 39 joules of stored energy per phase (assuming maximum torque). 例如,一个20匹马力的感应电机(230VAC线对线,4极,Y形连接)包括了大约每相39焦耳的储存电能(假设最大的扭矩)。
- But Anthony Trewavas, a biochemist at the University of Edinburgh, counters that organic farming actually requires more energy per tonne of food produced, because yields are lower and weeds are kept at bay by ploughing. 但是爱丁堡大学的安施欧尼.;崔瓦拉斯反对说,采用有机耕作方式每吨粮食实际上需要更多能源,因为产出更低而且耕作过程中还要拔除杂草。
