Under sudden precipitation, a rapid increase of the whole-plant sap flux was observed, but the increase lagged behind the peak time of the precipitation. 在遇到突发性降雨时,中间锦鸡儿整株丛树干液流量会随着降水的增加而迅速升高,但时间上要滞后于降水量达到最大值的时间。
Measurement of Absolute Neutron Flux Density by Peak Area Ratio Method 峰面积比法测量绝对热中子注量率
The results showed that methane emission flux presented distinct diurnal and seasonal variations. Methane emission flux reached the highest peak from 14:00 to 16:00 pm, and the lowest value between 0:00 and 4:00 am. 结果表明:甲烷排放通量日变化呈现一定的规律,排放高峰出现在下午14:00~16:00,晚上0:00~4:00达到最低值。
Effects of the Aharonov-Bohm flux to the soliton in a one-dimensional ferromagnetic ring are investigated. The effects on the peak, the width, the rest energy and the effective mass of the soliton by the Aharonov-Bohm flux are shown. 分析了Aharonov-Bohm磁通对一维铁磁链中孤子的影响,结果表明Aharonov-Bohm磁通对孤子的峰值、宽度、静止能量及有效质量均有影响。
The parameters of the NAM hydrological model are researched on affecting the depth of runoff volume, flood peak flux and flood peak appearance time. 利用灰色系统关联分析方法来研究NAM模型参数对模型模拟径流深、洪峰流量和峰现时间的影响。
The seasonal and annual variations of pure ozone flux in Southern Hemisphere have two peak values which show the structure of unsymmetrical seasonal wave, which is completely contrary with Northern Hemisphere. 南北半球臭氧净通量的变化趋势相反,南半球为双峰结构,表现为非对称振幅的季节波动结构。
Dustfall flux in the peak was in Zhangjiakou, the lowest areas were in the center of Handan and Tangshan which was formation of high and low ends of the distribution trend. 降尘通量的高值中心在张家口,中低值区又分别以邯郸和唐山为中心形成两端高中间低的分布趋势。
The transient signal characteristics of the 3D pulsed magnetic flux leakage with defects in different directions were studied, and a new method using 3D pulsed magnetic flux leakage transient signal peak scanning waveform to classify the circumferential defects and axial defects was presented. 研究了不同走向缺陷三维脉冲漏磁瞬态信号的特点,提出了一种利用三维脉冲漏磁瞬态信号峰值扫描波形来识别周向缺陷和轴向缺陷的新方法。
