阿尔及利亚D 区块储层特征及影响因素分析

下泥盆Siegenian 组砂岩储层是阿尔及利亚D 区块的主要勘探目的层。研究其储层特征及控制因素对勘探潜力的评价及后期开发有着重要的指导意义。经过研究，块内砂岩类型主要为石英砂岩，岩屑石英砂岩，储层储集空间主要为各种类型的次生孔隙和少量的裂缝，原生粒间孔不发育，多为粒间溶孔、粒内溶孔及微裂隙。孔隙结构主要为中小孔微细喉，储层物性较差，为中低孔、特低渗储层类储层；储层性质主要受到沉积条件和成岩作用的控制，成岩作用中以压实作用和溶蚀作用对储层物性影响最大，其次是胶结作用和交代作用。     

Three‐Stage Decision‐Making Model under Restricted Conditions for Emergency Response to Ships Not under Control

A ship that is not under control (NUC) is a typical incident that poses serious problems when in confined waters close to shore. The emergency response to NUC ships is to select the best risk control options, which is a challenge in restricted conditions (e.g., time limitation, resource constraint, and information asymmetry), particularly in inland waterway transportation. To enable a quick and effective response, this article develops a three‐stage decision‐making framework for NUC ship handling. The core of this method is (1) to propose feasible options for each involved entity (e.g., maritime safety administration, NUC ship, and ships passing by) under resource constraint in the first stage, (2) to select the most feasible options by comparing the similarity of the new case and existing cases in the second stage, and (3) to make decisions considering the cooperation between the involved organizations by using a developed Bayesian network in the third stage. Consequently, this work provides a useful tool to achieve well‐organized management of NUC ships.     

汉语新词语现状及共管理策略刍议

语言是随着经济、社会、文化的发展而不断发展的。我们所处的时代瞬息万变，汉语新词语不断涌现。对此，学界存在着或否定或欢迎等不同态度。我们认为，吐故纳新是汉语的一大特性，我们应坚持开放宽容而又积极规范的态度，一方面大胆包容新词语不断出现的现象，一方面采取一定的措施加强语言的规范管理，处理好语言共性与个性的关系，使汉语发展既保持稳定性又富于创造性。     

“环辽经济带”的辽商轨迹

上期说到张学良原配夫人于凤至的时候,提到了其父于文斗所在的辽源,是“环辽经济带”的一环,有人就问了:这个“环辽经济带”咋形成的?现在提这个经济带的概念,还有没有现实意义? 当然有现实意义! 所谓环辽经济带,上期说了,就是围绕辽宁中部都市群,沿着省境内外,从古至今形成的巨大经济带.历史上,从丹东(甚至从朝鲜新义州),到河北秦皇岛(山海关),形成了几十个大小城市、商埠,以历史与地理的叠加角度看,这条经济带是若隐若现:乱世,就隐了,断裂了;盛世,就现了,就连接起来.     

阻沙率在沙漠公路高大沙丘段防沙体系设计中的应用

在工程防沙设计中，阻沙率和输沙强度均是确定防护类型及其宽度的重要指标。从工程实际出发，结合典型地形特征，运用实测的阻沙率指标，优化沙漠公路高大沙丘段防沙体系的设计，用理论指导实践的同时，并在实践施工中加以较好地运用，从实践效果上，以阻沙率这一风沙物理指标为依据，确定高大沙丘段的防沙设计参数，是符合实际和可行的方法。     

The empirical Bayes estimators of the parameter of the Poisson distribution with a conjugate gamma prior under Stein's loss function

For the hierarchical Poisson and gamma model, we calculate the Bayes posterior estimator of the parameter of the Poisson distribution under Stein's loss function which penalizes gross overestimation and gross underestimation equally and the corresponding Posterior Expected Stein's Loss (PESL). We also obtain the Bayes posterior estimator of the parameter under the squared error loss and the corresponding PESL. Moreover, we obtain the empirical Bayes estimators of the parameter of the Poisson distribution with a conjugate gamma prior by two methods. In numerical simulations, we have illustrated: The two inequalities of the Bayes posterior estimators and the PESLs; the moment estimators and the Maximum Likelihood Estimators (MLEs) are consistent estimators of the hyperparameters; the goodness-of-fit of the model to the simulated data. The numerical results indicate that the MLEs are better than the moment estimators when estimating the hyperparameters. Finally, we exploit the attendance data on 314 high school juniors from two urban high schools to illustrate our theoretical studies.     

An Extended Single‐index Model with Missing Response at Random

An extended single‐index model is considered when responses are missing at random. A three‐step estimation procedure is developed to define an estimator for the single‐index parameter vector by a joint estimating equation. The proposed estimator is shown to be asymptotically normal. An algorithm for computing this estimator is proposed. This algorithm only involves one‐dimensional nonparametric smoothers, thereby avoiding the data sparsity problem caused by high model dimensionality. Some simulation studies are conducted to investigate the finite sample performances of the proposed estimators.

Hazard rate ordering of the second-order statistics from multiple-outlier PHR samples

In this paper, we compare the hazard rate functions of the second-order statistics arising from two sets of independent multiple-outlier proportional hazard rates (PHR) samples. It is proved that the submajorization order between the sample size vectors together with the supermajorization order between the hazard rate vectors imply the hazard rate ordering between the corresponding second-order statistics from multiple-outlier PHR random variables. The results established here provide theoretical guidance both for the winner's price for the bid in the second-price reverse auction in auction theory and fail-safe system design in reliability. Some numerical examples are also provided for illustration.     

利用微信平台开展高校就业服务指导工作的思考

随着高校就业工作信息化建设的推进，微信平台成为开展就业服务指导工作的新阵地。利用微信平台开展就业服务指导工作形式新颖、便捷且吻合“90后”大学生的特点。但目前就业指导服务微信平台的全程性存在质疑、有效性存在障碍等问题，影响了它的实际效用。应当首先对微信平台的优势进行准确定位，其次要不断拓展高校就业服务指导微信平台用户数量的广度和深度，再次要提供更优质的个性化服务，以期促进高校就业服务指导微信平台有效、优质的运营。
