概率比

Although there have been theories akin to the rising flow that were outright vehicles for vitalism, a second force doesn't have to be any less scientific than the laws of probability or Darwin 's force of natural selection.

然而并非没有类似上升潮的理论，例如已经广泛传播的"生机论"。这第二种力量的观点，与概率律或者达尔文的自然选择说想比，并没有任何非科学之处。

The center of mass motion of the cold atoms exhibits wave nature of quantum mechanics.

由于这种量子力学波动性，粒子能够从一定的概率隧穿过比其能量更高的势垒。

Using hydrodynamical/N-body simulations and pure dark matter simulations, we found the dark haloes in the first kind of simualtions are more concentrated than in the second kind of simualtions. This result could increase the predicted probability of giant-arcs in gavitational lensing and cancel the great difference between the theoretical and observational results.

用含气体的数值模拟与纯暗物质的数值模拟比较，发现前者暗晕中的暗物质分布比后者中的更加密集，密集参数更大，这可能可以提高理论预言的引力巨弧的概率从而弥补理论与观测结果间的差距。

The entropy-directed algorithm needs manual intervention to construct fault isolation strategy,and it is ofεhigh computation complexity.Theoretical analysis and experimental results illustrate that the entropy indirected algorithm remedies such deficiency. The MFIT of the strategy by this algorithm is about 38% less than that by the entropy- directed algorithm under the assumption of unequal fault rate.

实验验证和理论分析表明，该方法弥补了直接熵法构造故障隔离策略时需进行人工干预、计算复杂性高的不足；在不等故障概率的假设条件下，平均故障隔离时间比直接熵法减少约38%。

In the end, the spectrum expression of nonuniformly sampled LFM signal in the fractional Fourier domain is derived, and the detection probability of the signal in the case of different SNR is studied.

最后，应用该方法得到了非均匀采样LFM信号在分数阶Fourier变换域的频谱表达式，并对不同信噪比条件下信号的检测概率进行了研究。

There were higher rate with facial nerve paralysis in totalparotidectomy than segmentary parotidectomy or superficial parotidectomy.

行浅叶及肿瘤切除手术比行全叶及肿瘤切除手术损伤面神经的概率低。

We found that undernatural number coding the population size can be very small,about 6 to 10 is enough,which isvery different from the classic GA.

实验结果表明，这种并行算法实现简单，效果也不错，而且从概率算法的角度来说，这种并行算法的加速比可以认为是线性的

For finite number of frequency bins, the maximum throughput of synchronous system is about twofold to that of asynchronous system. It can be seen that the synchronous FH—CDMA system is related to slotted ALOHA system, and the asynchronous system is related to unslotted ALOHA system.

此外，还对ALOHA系统与FH—CDMA系统作了比较，得出：当要求分组错误概率较小时，FH—CDMA系统的吞吐量比ALOHA系统大得多；窄带系统中的时槽与FH—CDMA系统中的同步跳频相对应，而窄带系统中的非时槽则与FH—CDMA系统中的异步跳频相对应。

Based on the scalar scattering theory,a mathematical model of the light scattering intensity distribution of laser beam on the back focal plane of Fourier lens by a rough surface is established by means of the probabilistic-statistical method.

本文以标量散射理论为基础，用概率统计方法建立了粗糙表面的光散射强度在傅氏透镜后焦面上的分布的理论模型，采用镜反射方向的光强与某一散射方向的光强之比来计算R_q值的方法，导出了理论计算公式。

The results indicate that it is more accurate to estimate joint frequency by using probability matrixes than frequency matrixes.

结果表明，在计算联合频率中应用风向和风速概率矩阵比应用频率矩阵更准确、可靠。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
