Here heavy rain means rainfall exceeding 30 mm in an hour , the criterion for amber rainstorm warning . this increase is far less than the year - to - year fluctuation of the number of heavy rain days ( ranging from 1 to 13 days per year ) 4天，即由50年代的约5天增至90年代的约6天左右，不过要注意这个上升数值远小于年际变化(由每年1天至每年13天不等) 。
In the case that hypocenter depth is far less than the epicenter distance without depth phases available , only the relative epicenter distribution could be obtained accurately by double difference method , the depth determined would be not stable 当震源深度远小于震中距时，如果没有深度震相的参与，只能得到误差较小的震中相对分布，深度的相对位置仍有较大的误差。
In 2003 , the most recent year for which figures are available , america ' s power - generation business , arguably the world ' s biggest single polluter , spent a rather smaller proportion of its revenues on r & d than did america ' s pet - food business 在有据可查且距今最近的2003年，美国发电行业的研发资金占其利润的比例远小于宠物食品业，而前者被认为是世界上最大单个污染源。
The user ' s call is random and the possibility of all the channels to be occupied at the same time is far lower than that of one channel , so the multi - channels sharing can increase the system ' s capacity and the utilization factor of the channels 用户呼叫是随机的，所有n个信道同时被占用的概率远小于一个信道被占用的概率，因此多信道共用可以提高系统容量和信道利用率。
A silicon microchip carrying a gigabyte of data , for instance , has a shannon entropy of about 1010 bits ( one byte is eight bits ) , tremendously smaller than the chip ' s thermodynamic entropy , which is about 1023 bits at room temperature 例如，一个带有10亿位元组数据的矽微晶片所拥有的夏侬熵约是1010个位元（一个位元组有八个位元） ，远小于晶片的热力学熵? ?在室温时约为1023位元。
In detail , one - photon detuning for large kerr nonlinearity and photon switching via eit should be far less than the product of the ratio of intensity of the coupling field to the intensity of the signal field , and the detuning or the decay rate of the additional transition 具体来说，单光子失谐量的取值范围应远小于祸合场和信号场的强度比与微扰跃迁的失谐量或者衰减速率之积。
This dissertation is devoted to the study of vibration and radiation of combined structures with cylindrical shells . the main contributions are as follows : 1 . three problems emerged from traditional study of mobilities are pointed out 指出了传统导纳研究中经常忽视的三点问题：局限于点的研究；忽视激励的分布形式；忽视“结构的传递点导纳远小于结构的输入点导纳”这一结论提出的前提条件。
As the biggest library , if it is in disorder , is not as useful as a small but well arranged one , so you may accumulate a vast amount of knowledge , but it will be a far less value to you than smaller amount ? if you have not thought is over for yourself 正如一个最大的图书馆,如果它是无序的,那还不如一个虽然小但井然有序的图书馆有用,你可能积累大量的知识,如果你自己没有想透,它们的价值远小于少得多的知识
The calculated results show that the generation of inversionless gain in doppler - broadened media for a probe field wavelength in much excess of coupling field wavelength is possible , although the coupling field rabi frequency is significantly less than the doppler width 计算表明：在探测场波长远大于耦合场波长情况下，虽然耦合光的拉比频率远小于多普勒加宽，但是无反转增益依旧存在，而且强于匹配能级的增益。
The two analytic examples show that : if the heating and moistening due to convection at the switch - on point is much smaller than all the other terms in the tendency equation , then keeping the " on - off " switches the same as the basic state will produce the right tangent linear model and adjoint model 两个解析的例子表明：只要“开关”处的对流引起的加热和加湿远小于倾向方程的其它项，则保持“开关”变量与基态一致，能够正确得到切向线性模式和伴随模式。
