1The axial evolution law on the structure and the aerodynamic characteristics of the asymmetric flows around slender bodies of revolution at incidences is summarized:whether the flow asymmetry is powerless or powerful,the flow always appears in the structure that lee-side vortices rise,and shed vortices form,and new lee-side vortices come into being alternately on opposite sides of a slender body of revolution axially from nose apex downstream to afterbody,and always induces the sectional side force of waving quasi-sinusoidally downstream axially.

1总结出细长旋成体有攻角非对称绕流流场结构和气动力特性的轴向演化规律：无论非对称性强弱，沿轴向从头部尖顶往后体，非对称绕流总是呈现为左、右两侧背涡交替从物面向上飘起、形成脱落涡、再衍生出新生背涡的流场结构，并诱导出沿轴向呈类似正弦曲线形式振荡分布的截面侧向力。

4The correlations between the aerodynamic characteristics and the vortical structures of the flows around slender bodies of revolution at incidences are obtained.

4总结出细长旋成体有攻角非对称绕流流场气动力特性与背涡结构之间的相关性。

RESULTS:Isoalantolactone exhibited excellent anti-proliferative activities on HeLa, SHIN3 and HOC-21 and HAC-2 cell lines, while 1-O-acetylbritannilactone and britannilactone demonstrated weak anti-proliferative activities on HeLa, SHIN3, HOAC-21 and HAC-2 cell lines even at the concentration of 100 μmol/L. The apoptotic rate in isoalantolactone group with the concentration of 12.5 μmol/L was higher than that in PBS group.

结果： 异土木香内酯对上述5种肿瘤细胞的增殖均有明显的抑制作用，1-氧-乙酰大花旋覆花内酯和大花旋覆花内酯即使在100 μmol/L的高浓度下，对5种妇科肿瘤细胞的增殖不显示抑制活性；流式细胞学检查发现异土木香内脂处理后的HeLa细胞出现凋亡现象。

On the basis of an integrated analysis of the geochemical features of these volcanic rock associations,this paper concludes that thebasalts originated mainly from interaction between mantle-derived magma and low-crustal materials, and rhyolitic volcanic rocks resulted from thermal and chemical interaction between basaltic magma and the upper part of crustal materials.Basalts and rhyolites in different cycles have different source regions,and they are products of multiperiodic pulsive layer partial melting.

根据对火山岩地球化学特征的综合分析表明，玄武岩主要为幔源岩浆与下部地壳岩石相互作用的产物，而流纹岩则为玄武岩浆与上部地壳物质进行热及成分交换的结果，不同旋回的玄武岩和流纹岩有不同的源区，为多次脉动分层部分熔融的产物。

The femoral circumflex arteriography of the normal leg was done in 8 patients, and three of them were simultaneously done in a postion of internal rotating of straight leg. Results Comparison with the arteriographic findings in absence of traction, all retinacular arteries but inferior arteries were depicted few branches and less femoral head perfusion in all 9 patients, especially in that of medial femoral circumflex arteriography, as hip joint was tractating in neutral position with the same speed and volume of injecting contrast medium and, the veins were demonstrated poorly or delayed.

结果同一血管部位，同等对比剂注射流率、总量造影，与中立位无牵引状态下造影所见比较，9例患髋中立位牵引时，除外下支持带动脉，所有未损伤的支持带动脉均有不同程度闭塞，相应股骨头颈部灌注不佳或几乎无灌注，静脉显影延迟或显示不清，4例牵引力由3kg增至5kg时，上述改变更为明显；5例患髋维持伸直内旋位时，所有支持带动脉尤其细小分支未见明确显示，股骨头灌注差或未见明确灌注，改变甚于牵引时；2例正常髋内旋位时造影改变类似。

The main technological innovation is as follows: Adopting collector Bp was of high-effect to float copper; using no-toxic and combinatorial depressants to depress lead, the experiment was carried out effectively for separation of copper-lead; Adopting processing of copper middle to concentrate a cyclone classificating and a mill regrinding, it solved the vicious cycle of the lead and was of low dissociation.

其主要技术创新点有：采用高效捕收剂BP实现铜铅优先浮选；采用高效无毒组合抑制剂实现铜铅的有效分离；采用铜中矿集中旋流器分级再磨处理解决了铅的恶性循环和单体解离度低，有效地解决了铜铅分离的技术难题。

The main products of our factory has mining sieve, hopper linings, rubber roller, rubber, seals, bumpers, hydrocyclone, friction plates, stripping film plate, coupling, plastic venues, as well as the mill, pump shell , roller bag plastic, rubber lining business.

我厂主要产品有矿用筛板，料仓衬板，胶辊，胶轮，密封圈，缓冲器，旋流器，摩擦板，剥片盘，联轴器，塑胶场地，以及磨机，泵壳，辊筒的包胶，衬胶的业务。

Because of the viscosity of fluid and non-existence of velocity potential, the symmetry of mass matrix, stiffness matrix and the coefficient matrix of the first order of system no longer exists, so the modal analysis of system becomes very complicated.

由于流体粘性的影响，流场有旋，没有速度势，所以系统质量阵、刚度阵以及一阶项的系数矩阵的对称性被破坏，从而使得系统的模态分析变得很复杂。

The simulation results of isothermal two-phase flows are in good agreement with PDPA experimental results, showing that the two-fluid model is reasonable.

应用新的程序软件对旋流燃烧器内冷态两相流动、有反应两相流动、煤粉燃烧和NO生成进行了数值模拟。

But the effect of the conducting tube shape and size on the fiber in the spinning is obvious, and affect the disc swirl spun yarn's quality.

但输送管道的具体尺寸对纺纱过程中纤维的状态有明显的影响，从而影响着旋流纺的成纱质量。
