The Magnetic Stereotaxis System is a unique less-invasive interventional operation device that is designed to deliver a small permanent pellet and an attached catheter directly into the vasculatures or soft tissues of a patient to perform complicated surgical operations under the control of spatial magnetic field distributions.

摘要磁导航外科手术系统是通过计算机控制磁场的空间分布,使预先植入人体内的铁磁小珠按照规定的路径运动,直接作用于患处或引导介入式导管在人体内进行各类复杂外科手术操作的一种新型介入式微创手术装置。

Without such detailed information, raking comes as a rescue since it requires only the knowledge of marginal distributions of selected variables. Popular as it may be, raking takes no account of associations among post-stratifying variables. Furthermore, it relies heavily on Chi-squared tests and a pre-selected p-value (usually 0.5) as the stopping rule of iteration, an ad hoc rule justified only by convenience.

因此,目前最常采用的是「反覆多重加权」的方式,但「反覆多重加权」实际执行时,最大的问题在於其检定方式是透过卡方检定,通常只要其检定P值大於0.5,就认定样本与母群一致,而未考虑一个最佳化的加权值。

If the wavelet energy frequency is less than 1 day^(-1), the distributions of storm surge graph are similar to that of energy curve.

在台风潮之小波能方面,得知频在1 day^(-1)以下的平均小波能,其能曲线与潮水位在时间上的分布相似。

We give some results on the strong law of large numbers for sequence of negatively associated random variables with different distributions.

给出了具有不同分布的NA随机变量列满足的若干强大数律;作为应用,不仅将独立随机变量的一类强极限定理完整的推广到NA随机变量情形,而且关于NA随机变量的一些已有结果可以作为推论得出。

Thirdly, proper probabilistic model is built for the bilateral stop-and-go generator and the probability properties of its output sequence are studied. It is proved that the output sequence obey strong law of large numbers and central limit theorem and that, however, the distributions of 0 and 1 in the output sequence are imbalanced, which implies that this generator cannot be used as keystream generator directly. The rate of coincidence between the output sequence and corresponding LFSR sequences, together with their first derivatives are obtained, which reveal the existence of correlation between these sequences.

最后,建立了双侧停走生成器的概率模型,研究了双侧停走生成器输出序列的概率分布性质和大数性质,证明了生成器输出序列服从强大数定律和中心极限定理,得到了生成器输出序列中0,1分布是不平衡的结论,由此指出不能将这种生成器直接作为密钥流生成器;给出了双侧停走生成器输出序列和相应的线性移位寄存器序列之间的符合率以及一阶差分序列之间的符合率,得到了符合率的表达式,揭示了这些序列的对应比特和对应序列段之间存在相关性。

The idea occurred to me that the relative steepness of the J-distributions on the scales that Woo used to measure custom conformity might also be predicted by the structural dynamics formula.

构思发生,我认为相对陡直的J型分布,对尺度的胡用来衡量定制整合也可能预测由结构动力学的公式。

However, on condition of heavy-tailed distributions, VaR dissatisfies convexity and subadditivity, and cant measure market risk validly.

然而,在厚尾分布条件下,目前最常用的市场风险管理模型VaR不满足凸性和次可加性,不能有效地度量市场风险。

The distributions of subaerial algae in Jilin's terrestrial ecosystem are different with the difference of zonal vegetations. The distinction is embodied in the species quatity and subaerial algae's thallus shape.

由于各种因素的综合影响,东北森林-草原样带中的各地带性植被内的亚气生藻类在分布上有较大差别,这种差别主要体现在种类数量和藻类的原植体形态上。

Topics covered include subjective notion of probability, Bayes' Theorem, prior and posterior distributions, and data analysis techniques for statistical models.

包括:概率的主观定义,贝叶斯理论,先验和后验分布,统计模型的数据分析技术。

The possible reason is that in shock waves a nonstoichiometric ferromagnetic zinc ferrite is formed, in which the distributions of the cations in the A and B sites of the sublattice are different from that formed in calcination, it has stronger exchange interaction and leads to the increase of the magnetization.

可能的原因是冲击波合成了非化学计量比的铁磁性铁酸锌,改变了尖晶石次晶格中A,B位阳离子的分布而使其具有更强的交换相互作用而导致其磁化强度的增加。
