The experiments indicate that the dynamic behavior of the cylinder under the axial fluid-solid impact loading differs from the dynamic buckling when they are axially impacted by impulsive loads and step loads of infinite duration. The structures exhibit three different critical conditions: plastic incipience, dynamic buckling and plastic failure.

研究结果表明：圆柱壳承受轴向流固冲击时的动力特性与承受轴向脉冲和阶跃载荷时的动力特性有着显著的不同，结构呈现三种不同的临界动力状态：塑性出现、动力屈曲和动力塑性失效。

The average correlative coefficients of linear regression function for isochronous stress- axial strain curve are 3.92% higher than that of average correlative coefficients of linear regression function for isochronous stress- radial strain curve, so nonlinear creep property of the fine sandstone specimen in axial direction is correspondingly weaker than that in radial direction.

应力－轴向应变等时曲线线性回归函数的平均相关系数高出应力－径向应变等时曲线线性回归函数的平均相关系数3.92%，因此其轴向非线性蠕变特性相对于径向非线性蠕变特性更弱。

The article analyses angle distribution of radiant energy flow density and angle distribution of radiant power when an electric dipole is oscillating along polar axis in magnetic anisotropic medium,also compares them with the expression of that in isotropic medium;thereby,a theoretical basis for more effectly using electric isotropic and magnetic anisotropic medium is obtained.

Seedlings under light absorbed more rutin than those in the dark at rutin concentrations of 60-80 μg/mL and absorbed less rurin at concentrations lower than 40 μg/mL or near 100 μg/mL. IAA (＞0.1 μg/mL) treatment promoted rutin accumulation and inhibited elongation of shoot axis and primary roots.

当培养基中的芦丁浓度为60～80 μg/mL时，光照下的幼苗比暗处理的幼苗在胚轴中积累更多的芦丁；而芦丁浓度为40μg/mL以下和接近100μg/mL时幼苗在光照下累积的芦丁较暗处理的幼苗更少。0.1μg/mL以上的IAA促进芦丁的累积而进一步抑制幼苗胚轴和主根的伸长。

Theoretical analyses show that the BRF has the maximum tuning rate when the optic axis is located on the cone with its symmetric axis being on the refracted ray and apex of 45°; and the rejection of unwanted wavelength of BRF becomes the maximum when the optic axis is in the plane which contains the refracted ray and makes the angle of 45° or 135° with respect to the incident plane.

分析表明当晶片光轴处在以折射光线为轴线、顶角为45°的圆锥面上时，双折射调谐器具有最快的波长调谐速率；当光轴位于过折射光线并与入射面成45°或135°的平面内时，调谐器抑制非所需波长的能力最强。

It simulation results proves that when the inner pipes in the concentric annulus pipes stand still, the turbulent flow nucleus area approaches inner pipes; and when inner pipes circumvolve, the turbulent flow nucleus area approaches outer pipes. The shearing velocity near the inner pipes is the biggest, and the shearing velocity increases with the velocity of the inner pipes increasing.

模拟结果表明：在同心环空管道中当内管静止时，紊流核心区即轴向速度最大值区域靠近内管壁；当内管旋转时，紊流核心区即轴向速度最大值区域靠近外管壁；靠近内管壁处的切向速度最大，且随着内管转速的增加切向速度增大。

电动时，传动路线如下：专用电机---蜗杆轴---蜗轮---离合器---输出轴；需要手动时，压下切换手

The criterion is similar to hyperbolic strength criterion including uniaxial compression strength and uniaxial tensile strength, which is an extended form of Griffith-Murrell criterion essentially under the condition of polyaxial stress when hydrostatic pressure is lower, and it represents the first failure type. However, the criterion is similar to generalized Mises criterion when hydrostatic pressure is higher, and it represents the second failure type. The transition part between the two criteria represents the third failure type when hydrostatic pressure is high.

该准则包含单轴抗压和抗拉强度，在静水压力较低时，实质上它是Griffith-Murrell准则在多轴应力状态下的一种扩展形式，反映脆性岩石破坏类型1；在很高静水压力下该准则可转化为广义Mises准则，反映脆性岩石破坏类型2；而当静水压力较高时，该准则处于上述两种准则的过渡阶段，反映脆性岩石破坏类型3。

The trajectory of the center point of cornea and the angle of eyeball was recorded by smear photography during the normal human eye saccadic movements. It was noticed that in the eye saccadic movement, the eye was not only rotating around vertical axis, but also performing a little rotation around coranal axis.

用高速摄影记录了正常人眼水平扫描运动时角膜中点的运动轨迹、眼球的转角等随时间的变化，发现眼球水平扫描运动时，不仅有绕垂直轴的转动，而且还有稍量绕横轴的转动。
