孔洞

There had the appropriate combination of two factors for the highest volatilization amount of NH3 under two patterns . The applying effect of this technique under different soil types , crop kinds , climate and hole stuff awaited more lucubration .

对于这项技术在不同土壤类型、作物种类、气候条件及孔洞不同填充物等条件下的应用效果仍有待作进一步深入研究。

It is found that, compared with the vacuum sintering, the magnet sintering at argon protection has lower density, magnetic-energy product and remanence, but coerciveforces are higher. The magnet has more and bigger pores, and there obviously exist loose microstructure, the Nd-rich phases are clearly distributed along the grain boundaries mainly in the shape of lumpish and lamelliform.

研究发现，与真空烧结相比，采用Ar保护烧结时磁体的密度、磁能积和剩磁相对较低，矫顽力较高，磁体中形成的孔洞较多，孔径较大，并有明显的显微缩松存在，富Nd相的数量明显较多，且主要呈块状和片状沿晶界分布。

Think about when the car is parked inside your garage attached to your house; and the remote starter is interfered by other radio frequency and accidently turned on.(Your naughty kid may do this. Or, some crooks try to open your garage door by emitting random radio signals; always lock the man door). The car will keep pumping carbon monoxide gas into the garage, and the poisonous gas will seep through any cracks or holes to get into the house. Your whole family may get kill because of this (sleeping through the night and never get up).

试想一下如果那辆汽车停在你的车库内，车库又是和房屋连在一起的那种，万一遥控启动装置被其他无线电频道干扰而意外启动（你家里顽皮的孩子可能会这样做的，又或者一些小偷也会故意发射一些随机的无线电信号来尝试打开你的车库门，因此门一定要锁好），汽车就会不断地在车库里面释放一氧化碳，而这些有毒的气体又会透过门缝或者孔洞钻进屋内，严重时甚至可以置全家人于死地。

The results show that fibers in China and Japan have some differences in micropore structure by comparison of their power and angles of scattering.Japan's fiber have more powerful scattering.

实验结果表明，通过散射强度与角度的曲线对比，说明了国产丝和日本丝在微观孔洞上的差异，日本丝从原丝到碳丝的散射强度都高于国产丝。

The thickness of the films and their refractive index were measured by a monochromatic ellipsometer.

相应薄膜的密度和孔洞率也作了理论计算和比较分析。

Therefore,whatever of simply or multiply connected region,as longas the dynamic thermal stress distribution is generated by a temperature fieldapplied at the surface of some two-dimensional cavities in the elastic medium,the method of this dissertation can always be used to analyze it.

本文的研究结果具有理论上定性的意义，因此，本文的分析方法适用范围是广泛的，无论是单连通型，还是复连通型，凡是弹性材料中二维孔洞表面由温度场引起的动态热应力分布问题均可应用本文的分析方法来进行分析。

Adopting the conformal mapping or rotation axis etc complex methods which areoften used to treat with the hole or cavity problem,a two-dimensional cavity ofeither simply or multiply connected region is projected into the interior of acircle or an annulus.As well as the global coordinate system is turned into thelocal coordinate system.

采用处理孔口问题最常用的映射函数和移轴等复变函数方法，把复杂的单连通区域和某些复连通区域型二维孔洞转化为简单的单位圆内区域或圆环区域，把整体坐标转为局域曲线坐标，而，最终把问题简化归结为一组无穷代数方程组的求解问题。

Based upon the idea of space partition and object decomposition, topological components of an area object with holes are defined by the use of the concept of neighborhood in the point set topology, which is a natural extension of the definitions for topological components of a simple area.

本文基于空间划分和目标分解的思想，利用点集理论中的邻域概念详细分析和描述带孔洞面目标的点集拓扑分量，这种描述方法实质上是简单面目标点集拓扑分量描述的一种自然延展。

In addition, the capacitance of the mesoporous carbon can be improved up to 30% after nitric acid treatment.

另外中孔洞碳材在硝酸处理后，可以提高30％的电容量。

In Olmec iconography, vegetal motifs spring from similar clefts and orifices, alluding to the cthonic, ancestral sources of fertility and life.

在奥尔梅克影像学，植物图案的春天从类似的裂缝和孔洞，暗指cthonic，以及祖先的生活来源的生育能力。

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。
