The main two cycles of the Xiangshan volcanic rocks and subsequent subvolcanic rocks have low ε〓 value (-7.46～-9.40), high initial 〓Sr/〓Sr ratio (0.70801～0.71201), old Nd model ages (1.54～1.70Ga) and relatively riched in radiogenic Pb.

相山两旋回火山岩及火山期后的次火山岩具有较低的ε〓值(-7.46～-9.40)、较高的I〓值(0.70801～0.71201)和较古老的Nd模式年龄(1.54～1.70Ga)，且相对富集放射成因铅。

At present, supinator syndrome can be diagnosed definitely according to the clinical symptom, and the examination with electromyogram is beneficial to diagnose this disease, hot it has not specificity. Moat patients of supinator syndrome often get satisfactory effects after conservation treatment, and the ones who are failed can get the improvement from surgical treatment timely.

旋后肌综合征主要根据临床表现确诊，肌电图检查有助于该病的诊断，但并不具备特异性；大部分患者经积极的非手术治疗可取得较满意的疗效，非手术治疗无效的患者及时采取手术治疗亦可获得满意疗效。

The numerical results show that the secondary flow is enhanced in the cross section vertical to the mainstream for the revised burner, the gas tangential velocity component increases, and the rotational flow is intensified.

结果表明：改进后的燃烧器明显地增加了垂直于主流方向截面上的二次流，气体的切向分速度增大，旋流程度增强，能够有效地改善煤气和空气的混合效果。

In most knees, correct rotation is approximately 3 degrees of external rotation compared to the posterior condylar axis.

在大多数的膝关节，正确的旋转是相对于股骨后髁轴有大约3度的外旋。

While AcMNPV and BmNPV had no stimulatory effect in nonsensitive cell lines BmNPV hr3 has been demonstrated to increase the transcriptional activity of cislinked hel510 promoter. In this study, Sf-21, Bm-N and Hi-5 cell lines were transfected with pBmhel510luc-hr3down, and then were infected with each of AcMNPV, BmNPV and HyNPV. The results indicated that viral factors could interact with hr3 to significantly copromote the transcriptional level of hel510 promoter.

BmNPV hr3已被证明具有增强子功能，将hr3与hel510启动子顺式连接的质粒pBmhel510luc-hr3down转染Sf-21、Bm-N和Hi-5细胞后，再用上述三种病毒分别感染每一种细胞，hel510启动子的转录活性得到显著提高，表明病毒因子能够识别hr3，二者通过相互作用，共同增强解旋酶基因启动子的转录水平。

Then comes the more powerful CH-47B with the Lycoming T55-L7C engine, which was introduced by Boeing after a production run of over 350 CH-47A's. On the B model there are nonsymmetrical rotor blades to increase the stability.

因此波音公司在推生产了350架CH-47A后，推出了更加强劲的配备莱克明T55-L7C发动机的CH-47B型。B型为提高稳定性，还配备了非对称性的旋翼桨叶。

The characteristics of this copolyimide in chemistry and photics were determined.High quality copolyimide film could be obtained by casting the copolyimide solution on glass plate.Then the copolyimide was made into waveguide by using advanced processing techniques.Test results at optical co...

共聚物材料在溶液状态下用旋涂法获得了较高质量的共聚物薄膜，并在此基础上采用先进的光波导工艺技术将该材料制备成条波导，测试结果表明该波导在光通信波段1550nm处的平均传输损耗小于0.66dB/cm，局部损耗在0.2dB/cm，进一步改进后有望获得性能优异的光电子器件。

The paper presents that high pressure water jet comminuting technology was used for coal slurry pulverization,and then the comminuted slurry will be graded in a hydrocyclone,the fineness particles obtained from the over flow will be floated,and the coarseness particles from the under flow will be comminuted again.

介绍了采用高压水射流粉碎煤泥的技术，粉碎后的煤泥颗粒经水力旋流器进行分级，对溢流口得到的颗粒进行浮选，对底流口得到的颗粒再次粉碎。

The simulations show that the flows in axisymmetric sudden expansions are inherently unstable. The self sustained precessing phenomenon is more obviously at the expansion ratio E=5 compared with another case (E=10) herein.

数值模拟结果显示，即使射流进入对称的圆筒中，突然膨胀后的流动也是不稳定的，在膨胀比E=5时射流的自维持旋进特征较为明显。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
