| 1. | A model for single peak distribution data 一种适用于拟合单峰分布数据的模型 |
| 2. | Some plants had single peaks each month , but others had two peaks per month 除狼牙刺外,所有植物日平均蒸腾速率均在8月最低。 |
| 3. | The structure of the frequency spectrums of the coupled ocean waves are complex and multiplex , the most of the spectrum types is of double or of multiple peak other than the special case of the single peak spectrum 混和浪的频谱结构是复杂和多样的,除个别情况下仍呈现为单峰外,多数为双峰谱和多峰谱。 |
| 4. | Diurnal and seasonal changes in tr of ceratoides spp . displayed typically a single peak . tr was higher and response was more sensitive to environmental factors in ceratoides spp 与霸王( zygophyllumxanthoxylum )和沙拐枣( calligonumrubicundum )相比,驼绒藜属植物及柠条( caraganakorshinski )的蒸腾速率较高、对环境反应较敏感。 |
| 5. | The granularity distribution of the soil before dynamic consolidation has double peaks , the dimension value is greater , and the average value is ; 2 . 51 . in contrast , the granularity distribution of tamped soil has single peak , the dimension value is smaller , and the average value is 2 . 39 夯前土的粒度分布表现为双峰,分维值较大,平均为2 . 51 ;而夯后土的粒度分布表现为单峰,其分维值变小,平均值为2 . 39 。 |
| 6. | Diurnal variation in transpiration rates for different plants followed a similar pattern ; transpiration rates were low in the morning , increased as temperature and light intensity increased , and then declined again . transpiration rates for most plants had a single peak each day . some plants had two peaks per day 中午光照最强时,有些植物会出现午休现象,其日变化曲线表现为双峰型,同种植物在有些月份的日变化曲线为单峰型,有些月份又表现为双峰型。 |
| 7. | ( 3 ) from the viewpoint of physiology , its diurnal variation of transpiration rate seems to be a single peak curves which is consistant with the majority of trees in guizhou karst habitat , and whose maxium is 0 . 1908g . g - 1 . h - 1 , that is smaller than that of low peak form and the weak water - consuming type ( 3 )在生理上,迷迭香的蒸腾速率日进程为单峰曲线,与喀斯特生境中的大多数树种相一致,峰值为0 . 1908g . g ~ ( - 1 ) . h ~ ( - 1 ) ,比喀斯特低峰形低耗水型植物的峰值还低。 |
| 8. | The evaluation has been made for normally used four envelope functions of earthquake ground motion . being as evaluation standard of the envelope function this paper pointed out that the controlling capability of the parameters involved in functions of the peak position of the envelope with single peak and the shape of the envelope are essential besides simplicity of the formula of envelope function 本文对已经提出的四种经常使用的包线函数模型进行了评价,认为对于评价单峰点包线函数,除了要求形式简单以外,其优劣可以用函数对峰点位置和高峰隆起程度的控制能力作为标准。 |
| 9. | After analyzing , the author got the basic character of tidal flat hydrodynamic : the time of flooding on bare flat and ebbing is basically the same and the time of flooding on pioneer zone of salt marsh is a little short ; the process curve of current speed on bare flat did not appear peak value on the beginning of flooding and at the end of ebbing but presented double peak , that is , it presented double peak in winter and spring and ebbing peak value disappeared in summer and autumn , salt marsh presented single peak character in a year and the process curve in tidal creek presented double peak ; all current direction on every spot presented gyration current and the current speed changed rapidly during the high water level without obvious slack water period 分析得到了潮滩水动力基本特征:光滩水位涨潮和落潮时间基本相等,而盐沼前缘带水位涨潮时间略短;光滩流速过程线在涨潮初和落潮末出现峰值,呈现“双峰型”特征,盐沼前缘带则冬、春季节呈现“双峰型” ,夏、秋季节落潮峰值消失,盐沼带四季呈现单峰特征,潮沟内过程线为“双峰型” ;各测点流向均呈现回转流特征,在高水位时流向迅速改变,不存在明显的憩流。 |
| 10. | In the fourth chapter the pl and ftir spectra of porous silicon as - prepared and stored in atmosphere for one month were measured . the formers " pl only had single peak with lower energy while the latter appeared double peaks with a higher energy . through comparing the ftir spectra of the two samples we found si - o - si and o - si - h bonds appeared in the ftir spectra of the latter sample 新制备的多孔硅样品只有能量比较小的荧光单峰,存放一段时间后的多孔硅样品则出现了双峰;在红外光谱中原来存在的si一h : 、 si一h 、强度逐渐变弱,出现了对应于si一o一si 、 o一si一h的新峰。 |
