查询词典 scheme

The SCVFV(the convection-diffusion difference scheme based on control-volume face values) scheme was put forward. The theory of the SCVFV scheme was systematically elaborated. The general interpolation formula of the SCVFV scheme was given. The formulas of the SCVFV scheme based on the Cartesian coordinate were derived. The precision, the mass conservation property and the preventability of the false-diffusion of the SCVFV scheme were theoretically analyzed.

提出了基于控制容积面值的对流扩散差分格式SCVFV，系统地阐述了SCVFV格式的基本思想，给出了SCVFV插值公式的通用表达式，推导了直角坐标系下完整的SCVFV格式的表达式，从理论上分析SCVFV格式的精度、守恒性及反伪扩散性。

The results show that, with the same steel consumption, the longitudinal and transverse girder deck scheme is a little better in stiffness, dynamic characteristics and stability than those of the other scheme's. For the dense transverse girder deck scheme, because of no longitudinal beams, the axial forces of the tie beam and the deck slab are higher than those of the other scheme's. The improving rate of the axial force for the deck slab is about 50%. The inside and outside bending moments of the cross beams reduce to below half of the other scheme's. The longitudinal stress of the deck slab is higher on the whole and the traverse stress is less than that of the other scheme's. The maximum traverse stress of the deck slab is below 40% of the other scheme's.

研究结果表明：在材料用量相同时，纵横梁方案桥梁刚度较密布横梁方案的桥梁刚度稍大，桥梁动力特性比后者的优，其稳定性也比后者的强；对于密布横梁方案，由于不设纵梁，系梁和混凝土板承受的纵向力都较纵横梁方案的大，混凝土板增幅达50%左右，横梁面内和面外弯矩则明显减小，都低于纵横梁方案的一半，混凝土板顺桥向应力整体比纵横梁方案的高，而横桥向应力则较低，最大值低于纵横梁方案的40%。

Yet at least part of his argument here (toward these foundationalist ends of correspondence and realism) hinges upon demonstrating the untenability of certain foundationalist notions (chiefly confrontation and scheme/content dualism).

但至少他这里的部分论证（——指向结束于实在论和符合论的基础主义者）取决于对特定基础主义者观点（——简单说就是confrontation 和 scheme/content二元论）的untenability的论证。

Old LISPer that I am, I also looked at various current dialects of Lisp and Scheme--but, as is historically usual for Lisp, lots of clever design was rendered almost useless by scanty or nonexistent documentation, incomplete access to POSIX/UNIX facilities, and a small but nevertheless deeply fragmented user community.

老的LISPer，就像我，也看了各种各样的Lisp的方言和Scheme，但是就像Lisp一贯的作风，由于缺乏或者没有文档、不能完全接入POSIX/UNIX设备，以及那些虽然很好但很少的用户社区，使得许多聪明的设计变得毫无价值。

The coupling reaction of aryl iodides, bromides and chlorides with differentolefins catalyzed by catalyst 2 and 4 was studied. It was found that compounds 2 and 4 anchored on active carbon are efficient catalyst for the Heck reaction in the case of aryl bromides and aryl chlorides as substrates (Scheme 3). It is notable that catalyst 4 has higher efficiency for aryl chlorides.___^H Cat.2 or 4, Base HXSolution, 100C or 140
