抽样

The analysis for the relationship between the balance of quadricphase oversampled chaotic map sequence and sequence length and oversampled parameter p was given by using this function.

Methods 1 492 female students were clustered sampled from 6 middle schools in a povertystricken county in Anhui.One month's health education was given them,and the impact was evaluated with a questionnaire.

In order to improve the precision of super point detection and control measurement resource consumption, this paper proposes a super point detection method based on sampling and data streaming algorithms, and proves that only sources or destinations with a lot of flows can be sampled probabilistically using the SDSD algorithm.

为了提高超点检测的精度并控制测量资源的使用，提出了一种基于抽样和数据流算法的超点检测方法。

It also introduces the discrete ordinates couple-solving method (DOT-BSTP-DOT) which uses the half-symmetric angular quadratures for core geometry and the quadratic S〓 biasing angular quadratures for duct geometry. Calibrations for several types of duct are carried out and the schemes of XPR epithermal neutron filter are successfully designed. The other international popular code ANISN is also exploited and modified.

本论文首先开发、修改了其它国际通用屏蔽计算程序DOT/4.2和MCNP/4B，编制了边界源转换程序BSTP，首次建立深穿透屏蔽计算的临界源方向偏倚与指数变换相结合的蒙特卡罗耦合抽样方法，以及堆芯几何采用半对称求积基、孔道几何采用二阶S〓偏向求积基的离散坐标耦合求解法（DOT-BSTP-DOT），并对不同孔道进行了数值校算，成功地得到了西安脉冲堆超热中子过滤器的设计方案。

However, this effect was only seen after a latency of 10 years (years 0–9: 0·92, 0·56–1·49, p=0·73; years 10–19: 0·60, 0·42–0·87, p=0·007), was dependent on duration of scheduled trial treatment and compliance, and was greatest 10–14 years after randomisation in patients who had had scheduled trial treatment of 5 years or more (0·37, 0·20–0·70, p=0·002; 0·26, 0·12–0·56, p=0·0002, if compliant).

然而，这种作用仅在10年后才看到（0–9年： 0·92， 0·56–1·49， p=0·73； 10–19年： 0·60， 0·42–0·87， p=0·007），而且这种作用依赖于试验治疗安排的持续时间和顺应性，对试验治疗5年或5年以上的患者随机抽样，潜伏时间主要为10-14年(0·37， 0·20–0·70， p=0·002；如果顺应性好，0·26， 0·12–0·56， p=0·0002)。

但是这种效应只有经过10年的潜伏期才能体现出来(年数 0–9： 0·92， 0·56–1·49， p=0·73；年数10–19： 0·60， 0·42–0·87， p=0·007)，其取决于预定试验治疗和依从性的持续时间，并在随机抽样10-14年后在那些进行了预定试验治疗达5年或以上的病人身上体现最明显(0·37， 0·20–0·70， p=0·002； 0·26， 0·12–0·56， p=0·0002，如果依从的话)。

Howeer, this effect was only seen after a latency of 10 years (years 0–9: 0·92, 0·56–1·49, p=0·73; years 10–19: 0·60, 0·42–0·87, p=0·007), was dependent on duration of scheduled trial treatment and compliance, and was greatest 10–14 years after randomisation in patients who had had scheduled trial treatment of 5 years or more (0·37, 0·20–0·70, p=0·002; 0·26, 0·12–0·56, p=0·0002, if compliant).
