查询词典 two-by-four

Through the analysis of different cross section flow field in cylinder of two-valve and four-valve diesel engine, the following conclusion can be obtained: The formation of intake swirl of two-valve diesel engine mainly is effected by an intense air flow ring zone near the radius from valve axis to cylinder axis, as the flow progresses down through the cylinder, the ring zone air flow expends to both side and finally forms an unified rigid rotating swirl motion.

2号缸盖的螺旋进气道产生的绕自身气门轴线的动量矩比1号缸盖的大，且切向气道的径向速度在前峰面上的数值比1号缸盖的速度数值大很多，因此，两进气道组合后的动量矩损失也大，所以虽然2号缸盖的两个进气道单独的涡流比都高于1号缸盖的两个进气道，但组合后的合成涡流比却是基本相同的。

The project used in conjunction with three holes of a prestressed continuous box girder design, layout for cross-bridge 30m +30 m +30 m, two-way four-lane bridge to meet current conditions, after the completion of the construction of the bridge under the bridge to meet the 8-lane two-way traffic conditions.

Two kinds of DALF, DALFA and DALFB, was isolated in the DEAE-cellulose column using process elution method, SDS-PAGE analysis revealed the difference between the two eluates was the different ratio of H:L of the twenty four subunits.

通过离子交换层析柱(DEAE-52)分步盐洗脱技术，分离到两种不同分子量的蛋白质组分(DALF_A和DALF_B)，通过SDS凝胶电泳分析证明DALF_A和DALF_B不同之处在于蛋白壳的H和L亚基之间结合比例不同，由此形成释放铁动力学特性和铁核中的磷铁组成比也存在一定差异。

The calculated results show that azido in azides has linear structure , the most optimized CaN6 has linear structure , and the most optimized (CaN6)n (n=2～5) clusters have chain structure of perpendicularity of approximate diamond composed by two azido with two Ca atoms . The middle N atoms of azido show positive, the N atoms at both ends of azido show negative, and the N atoms effected with Ca atoms directly show more negative . There is strong ionic bond between the Ca and N atoms. The IR spectra of the most optimized (CaN6)n (n=1～5) clusters have four vibrational sections , the whole strongest vibrational peak lies in 2195～2280cm-1,and the vibrational mode is anti-symmetric stretching vibration of N-N bonds in azido . Stability analysis show that (CaN6)3 and (CaN6)5 clusters are more stable than other clusters .

结果表明，叠氮化合物中叠氮基以直线型存在，CaN6团簇的最稳定结构为线型结构，(CaN6)n(n=2～5)团簇首先由两个叠氮基与两个Ca原子构成一个近似菱形，再由菱形相互垂直形成链状最稳定结构；叠氮基中间的N原子显示正电性，两端的N原子显示负电性，且与Ca直接作用的N原子负电性更强，金属Ca原子和N原子之间形成很强的离子键；(CaN6)n(n=1～5)团簇最稳定结构的IR光谱分为4个部分，其最强振动峰均位于2195～2280cm-1，振动模式为叠氮基中N-N键的反对称伸缩振动；稳定性分析显示，(CaN6)3和(CaN6)5团簇相对于其他团簇较为稳定。
