查询词典 divergence

The intergeneric phylogenetic trees of water lilies showed that Nelumbo and Ceratophyllum form a sister group, but with relatively high sequence divergence, supporting that place the two genera into two distinct families; and Brasenia and Cabomba form a sister group, with relatively low sequence divergence, supporting that the two genera were placed the same family Cabombaceae.

结果表明：莲属与金鱼藻属构成姐妹群，但序列分歧度较大，支持将两个属独立成科的观点；莼菜属与水盾草属构成姐妹群，且序列分歧度较小，支持现有的莼菜科处理。

High genetic divergence, and thus low gene flow, was estimated among Otto and Chall Huaco whereas within each mountain range among-population divergence depended upon site characteristics.

Based on the real observation data, forecast equitation or forecast model, the dynamics method such as divergence and vorticity calculation, real data correction, ascending and subsidence calculation was used to simulate the 4D field of divergence, vorticity and vertical velocity at different time, different range and different levels. The field was connected to 3D fields of insect trajectories, yielding the flying speed, direction, ascending area and subsidence. Thus the peak of immigratory insect could be timely monitored. A system of the peak of immigratory insect forecast was set up.

根据实际观测资料、数值预报方程或数值预报模式等输出的风场网格化处理结果，利用运动学方法、散度推算法、涡度推算法、实际资料订正法、升降法等对不同时间、不同范围、不同层次的四维散度、涡度和垂直运动速度场进行计算或模拟，将计算或模拟得到的散度场、涡度场、垂直运动速度场与昆虫迁飞的三维气流场联系起来，得到该类昆虫所具有的迁飞速度、方向、上升区和下降区，从而对昆虫的迁入峰进行实时预警。

It is shown that GPS/PWV data with an time interval of 30 minutes reflected spatial and temporal changes of atmospheric vapor intuitionally and duly, the features of GPS/PWV changes had corresponding relations with the precipitation, the divergence of GPS/PWV showed the distributions of the convergence and divergence of atmospheric vapor.

分析还表明：每30min一次的GPS/Pwv资料能直观地、及时地反映大气中水汽的时间变化和空间变化；GPS/Pwv资料随时间的演变特征与降水有较好的对应关系；GPS/Pwv的散度资料可以反映大气中水汽的辐合、辐散分布情况。

The concept of entropy is applied to define an index on evaluating the abnormal condition. Prediagnosis of machine fault is made using the spectral structure distribution divergence as a criterion, in which the J divergence concept and multi-parameter evalution theory that describe the pseudo distances between the sampling signals and the corresponding standard faulty signals are used.

为此，基于信息熵提出了一个机组起停车过程转子运行状态的评估指标，并在此基础上，为实现机组运行故障早期预诊的目的，进而基于J散度及多参数评估理论，提出了信号频谱结构分布散度的概念，以描述实测信号与机组典型故障信号间的伪空间距离，从而实现了机组运行故障的初步预诊。

By analyzing the strange behaviors of massless integrations in dimensional regularisation, It was proposed that for a special kind integration, which is sero mathmatically, should not be simply treated as sero physically, as a fact it is the difference of the same magnitude ultraviolet divergence and infrared divergence.

通过研究维数正规化中的无质量积分的奇妙特性，本文指出对一种特殊类型的动量积分，从数学上看DR给出的结果为零，但物理上不能把结果简单处理为零，而是反映了大小相等的紫外和红外发散之差。
