To use solid immersion lens is one of the practical methods to realize the near-field high-density optical data storage.

采用固体浸没透镜的光存储方法是提高光存储密度的比较实用的近场光存储方法，而严格控制SIL下底面与光存储介质之间的亚波长级距离是此光存储系统正常工作的前提。

To use solid immersion lens is one of the practical methods to realize the near-field high-density optical data storage. But the storage system will work only on the condition that the distance between the bottom of the SIL and the surface of media is exactly controlled within the sub-wavelength scale.

采用固体浸没透镜的光存储方法是提高光存储密度的比较实用的近场光存储方法，而严格控制SIL下底面与光存储介质之间的亚波长级距离是此光存储系统正常工作的前提。

Solid immersion lens was employed to increase the optical writing density. The position of foci and numerical aperture of the focusing system with SIL were simulated, and the threedimensional optical data storage was conducted.

为进一步提高光存储密度，利用固体侵没透镜与数值孔径为0.55的长工作距离物镜对飞秒激光脉冲进行聚焦，完成了PMMA及石英介质上的存储实验，并对聚焦物镜焦点与SIL底面离焦时的介质内焦点位置和系统的数值孔径进行了模拟。

The underside of this inchworm measures your baby up to 24 inches.

这尺蠖的底面措施宝宝高达 24英寸。

For this situation, the method of rubber vibration isolator fixed on the side and back face is adopted to reduce noise created by the inertial force.

针对此种情况，采用在侧面和底面加装橡胶隔振器方法来降低其引起的振动噪声。

An identification algorithm for tool interference in NC machining is presented based on the fuzzy inference techniques and pattern recognition theory.

基于模糊推理的自由曲面描述方法和模式识别理论，提出一种适用于不同刀具类型并可同时考虑刀具底面干涉和侧面干涉的刀具干涉判别算法。

The overcutting on tool end is checked via comparing the tool radius with the circumradius or the radius of inscribed circle, and the touch interference of tool body based on the symbol of the vector distance from the triangle vertex to the tangent plane of tool body column.

在曲面加工的无干涉路径规划中，通过恰当选择刀具初始位置避免了接触点处的曲率干涉；通过比较刀具半径与曲面上三角片外接园半径的大小即可判断刀具底面干涉；而根据三角片顶点与刀杆切平面的有向距离的正负来判断刀杆碰撞干涉。

According to drawing up isopach map of salt in The Kuche depression and isobath map of the top and bottom of salt bed, preliminarily determined the relationship between zhe distribution of the structure and thickness variation of zhe salt bed: the salt bed is relatively thin in the pocket basin, but thick in both sides of the structure belt.

通过编制库车坳陷盐层等厚度图及盐层顶、底面等深度图，初步确定了盐相关构造分布与盐层厚度变化之间的关系：盐层厚度在袖珍盆地较薄，而在两侧构造带厚度较大，盐层厚度较大的地区大致围绕袖珍盆地呈半环带状分布。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
