以“贴近纳新”理念改进 任职教育军事专业课教法的几点思考

深化以任职教育为主体的教学方法改革，是顺应当前武警部队职能任务多样化的必然要求。任职教育适应岗位任职能力的需要必须注重加强军事专业课教学方法的改革与探索。“贴近纳新”把贴近职能需要纳入教学理念、贴近任职实际纳入组教模式、贴近岗位实用纳入课题施教为着眼点，旨在适应任职教育岗位任职能力培养的需要。     

Defensive weapons and star wars: a supergame with optimal punishments

We model the perspective faced by nuclear powers involved in a supergame where nuclear deterrence is used to stabilise peace. This setting allows us to investigate the bearings of defensive weapons on the effectiveness of deterrence and peace stability, relying on one-shot optimal punishments. We find that the sustainability of peace is unaffected by defensive shields if the latter are symmetric across countries, while asymmetric endowments of such weapons have clear-cut destabilising consequences.     

The war after next is here – what does the elephant look like?

A comprehensive paradigm of future wars can be defined, and is called in this article “Extended conflicts.” These can be characterized by strategic attrition, to which all national resources and all possible international legitimacy are mobilized, in order to achieve a resolution by transformation of the opponent. The use of military force in this kind of conflict is limited. The understanding that we are facing an era of extended conflicts will improve the way it is utilized.     

基于多栅格的基建营房保障信息耦合研究

合理利用军地资源实施一体化保障是现代战争或非战争军事行动基建营房保障的重要内容，然而，包含大量此类信息的商用网络、行业网络和平时基建营房业务管理网络的信息如何能被有效利用却是一个令人头疼的问题。依托军事信息栅格和地方多个行业信息网络，研究、设计缓冲数据库和数据订制服务软件，安全可靠地将分布在多个信息栅格中的基建营房保障所需信息耦合到军事后勤信息网络中，为快速、科学制定基建营房保障计划和实施战时基建营房一体化保障提供强有力的信息支持。

均匀设计在柴油无灰节能降污添加剂配方研制中的应用

基于低压氧弹燃烧法研究了充氧压力分别为0．6MPa和0．9MPa时两种无灰型柴油添加剂不同配比对助燃性能的影响。采用均匀实验设计和Matlab回归优化的方法，得到复配体系的最优配方，并对其进行了验证。结果表明，由Matlab回归分析得到的完全二次回归模型最理想，0．6MPa时由该模型得到的最优配方为：添加剂A和B的质量分数分别是0．300‰和0．700‰，并通过实验验证得到的发热量达到最大，变化率为8．697％。0．9MPa时，结合直观分析和回归分析，得到与实际相符的最优配方：添加剂A和B的质量分数分别是0．600‰和0．900‰，此时发热量皮化率为4．453％。

Estimating failure time distribution and its parameters based on intermediate data from a Wiener degradation model

Instead of measuring a Wiener degradation or performance process at predetermined time points to track degradation or performance of a product for estimating its lifetime, we propose to obtain the first‐passage times of the process over certain nonfailure thresholds. Based on only these intermediate data, we obtain the uniformly minimum variance unbiased estimator and uniformly most accurate confidence interval for the mean lifetime. For estimating the lifetime distribution function, we propose a modified maximum likelihood estimator and a new estimator and prove that, by increasing the sample size of the intermediate data, these estimators and the above‐mentioned estimator of the mean lifetime can achieve the same levels of accuracy as the estimators assuming one has failure times. Thus, our method of using only intermediate data is useful for highly reliable products when their failure times are difficult to obtain. Furthermore, we show that the proposed new estimator of the lifetime distribution function is more accurate than the standard and modified maximum likelihood estimators. We also obtain approximate confidence intervals for the lifetime distribution function and its percentiles. Finally, we use light‐emitting diodes as an example to illustrate our method and demonstrate how to validate the Wiener assumption during the testing. © 2008 Wiley Periodicals, Inc.
