1·It is suggested that the specific speed would be replaced by diametric ratio, and the new nameplate would be used.

建议比转速应为直径比所取代，并启用水斗式水轮机新铭牌。

2·Distribution rule of the arbor in different diametric class was investigated by sampling survey and statistical analysis, then expanded to the whole area in Beijing.

而树种实有植株径阶分布状况，则通过抽样调查、统计分析得到样本径阶分布规律，再将该规律扩展到北京城区乔木实有植株。

3·Observing vascular morphological and diametric changes of low leg on 30 cases with nodular vasculitis using Duples and Colour Dopplar Ulrtasound, 20 normal people as controls.

对病理活检确诊的30例结节性血管炎患者、20例健康者，采用双功能彩色多普勒超声扫描仪观察其下肢血管的形态和管径。

4·Mechanical characteristic of ct is studied. The model of bending, internal pressure strength and external collapse strength, diametric growth and stuck-point of ct is established.

研究了连续油管的工作力学特性，建立了连续油管弯曲、抗内压强度和外部挤毁压力、直径增长、纵向伸长及卡点位置分析计算模型。

5·Therefore we point out a new method of testing fragile material's strength of extension. That is to say we can measure the disk's strength of extension by pressing in its diametric.

从而对脆性材料抗拉强度的测定提出了一种新的方法，即通过对圆盘沿直径对心受压试验可测出其抗拉强度。

6·The static and dynamic strain tests are made for the buried tube at the scene. With the corresponding calibrated equations, the diametric displacements at the particular points are obtained.

并对现场埋设的管道进行静、动态应变测试，利用相应的标定方程获得特定点的径向位移。

7·However, the existence of those challenges can by no means serve as a pretext for us to withdraw into our nationalistic mindset, to pose China in diametric opposition to the rest of the world.

但是，这些挑战的存在，绝不应该被我们当作一种借口，来让我们退缩到民族主义的思维定势之中，将中国与整个世界绝然对立起来。
