The development mode that has disjunct part of design and custom converts the develop process from responsive customization to pre-customization, which is the importance requirement of DFMC.

主要工作包括如下几个方面：（1）研究了DFMC对设计的要求和设计过程特点，提出了DFMC的研究框架，主要包括产品族开发和配置设计等内容，通过设计和定制分离的开发模式，实现了从反应式定制设计到预定制设计的转变，；（2）提出了多目标约束环境下的产品族设计方法，以及应用动态QFD响应变化的用户需求规划产品族的思路。

Pre-interventionresearches show that attribution to effort is positively effective for both winnerand loser,keeping individual's higher expectation of success and enforcingpersistent behavior during competition break.Whereas,positive effects ofattribution to ability and luck are limited.They have effects on expectation ofsuccess,which changes disparately to success and failure.

前干预研究表明：在直接的归因定向中，努力归因无论对成功者还是失败者都具有十分积极的效应，不仅能够促使个体保持较高的成功期望水平，而且可以增强竞赛间歇的坚持行为；而能力与运气归因则不然，它们的积极作用十分有限，仅仅表现在对成功期望的影响上，并将视成功还是失败发生迥然不同的变化。

并在术前提供精确的解剖信息、术中监控和术后随访评估等各个过程中具备重要的临床应用价值。

According to generalized modular design, finite element models of each function module are built in ANSYS, which belong to pre-tightening frame of 45 MN forging press. MPC banded contact is used to simulate the connection of two fixed parts, while standard contact is used to simulate the connection of two dissociable parts, Deformations and stresses of the forging press under two working conditions are discussed, which provide good guides to the design of such kind of press.

On the basis of theoretical analysis of target diffusion in range-velocity resolution cell, the array signal covariance matrix and noise covariance matrix are estimated from some different cells respectively. The processing results from experimental data in onshore HFSWR with Minimum Variance Distortionless Respose, MUltiple SIgnal Classification and pre-whiten MUSIC respectively show that super-resolution methods can provide better resolution than CBF.

鉴于 HFSWR 工作波长较长、常规波束形成角分辨力较差的缺点，基于目标在距离—多普勒平面分布的理论分析，本文利用相邻距离、多普勒频率单元信号估计阵列协方差阵，并分别利用 MVDR 、 MUSIC 、预白化 MUSIC 方法进行超分辩处理，实测的合作飞机目标数据处理结果表明超分辩方法能明显提高阵列角度分辨力。
