复杂岩性地区岩性识别与储层预测

中国陆相地层岩性成分较为复杂,岩性波阻抗值常呈多极分布。水动能强度的急剧变化、高频率的水进水退等沉积背景造成了薄互层广泛发育的特点。储层间干涉现象普遍存在,直接影响到地震岩性解释的精度。针对复杂岩性地区岩性–波阻抗关系复杂的特点,系统分析了造成传统地震储层预测方法解释误差的原因。根据复杂岩性的地球物理响应特点,选取对区分复杂岩性敏感的测井参数。同时,将90° 相位化地震数据作为测井参数反演的相对波阻抗约束数据体。研究结果表明,该方法对复杂岩性进行了有效的区分,达到了精细描述复杂岩性地区储层空间发育及平面展布特点的目的。     

Serial unblocked designs balanced for correlation between neighbours,II

The theory in Part I contained an error that was inferred from the output of a program, written in SAS by Eric P. Smith and David D. Morris. The program produces random BUS designs in accordance with the algorithm of Part I. The theory is here corrected by using a combinatorial argument that involves elementary number theory. The algorithm needs no change but its interpretation is now adjusted.     

Probabilistic Inversion in Priority Setting of Emerging Zoonoses

This article presents methodology of applying probabilistic inversion in combination with expert judgment in priority setting problem. Experts rank scenarios according to severity. A linear multi‐criteria analysis model underlying the expert preferences is posited. Using probabilistic inversion, a distribution over attribute weights is found that optimally reproduces the expert rankings. This model is validated in three ways. First, consistency of expert rankings is checked, second, a complete model fitted using all expert data is found to adequately reproduce observed expert rankings, and third, the model is fitted to subsets of the expert data and used to predict rankings in out‐of‐sample expert data.

从解释世界到改变世界--马克思对黑格尔哲学的"颠倒"

马克思哲学是对传统哲学特别是黑格尔哲学的“颠倒”,主要体现在:对思想把握世界方式的颠倒、对“从天国降到人间”的颠倒、对理论和实践关系的颠倒。这些颠倒从根本上说是从解释世界的逻辑到改变世界的逻辑,这也正是马克思哲学所实现的哲学变革。     

IMPROVING THE NUMERICAL TECHNIQUE FOR COMPUTING THE ACCUMULATED DISTRIBUTION OF A QUADRATIC FORM IN NORMAL VARIABLES

This paper is concerned with the technique of numerically evaluating the cumulative distribution function of a quadratic form in normal variables. The efficiency of two new truncation bounds and all existing truncation bounds are investigated. We also find that the suggestion in the literature for further splitting truncation errors might reduce computational efficiency, and the optimum splitting rate could be different in different situations. A practical solution is provided. The paper also discusses a modified secant algorithm for finding the critical value of the distribution at any given significance level.

制度逆变、策略性妥协与非均衡治理——基于L村精准扶贫实践的案例分析

通过对L村精准扶贫实践的案例研究发现,由于贫困识别过程中村民争当贫困户、非均衡的项目实施及“任务式”扶贫产业开发,导致了农村精准扶贫的制度逆变及村民“气”的不断累积。在此背景下,基层政府通过博弈情景下的政策变通、村庄政治生活的选择性平衡及日常治理中的“做工作”等路径,建构了精准扶贫场域下村庄矛盾调处的策略性机制。由于治理主体之间连带性制衡关系的异化及治理结构与治理能力的非对称性,农村精准扶贫呈现非均衡性治理的悖论。在当前农村精准扶贫的政策实践过程中,需要建构“均衡性治理”的制度体系,推进贫困治理体系与治理能力的现代化。
