小孔

The parameter of laser energy transfer efficiency is used in the new model with a clear physical meaning for the first time. The mean absorption factor of laser induced plasma to the laser within the keyhole is calculated according to different welding parameters using the relative intensity method of spectral lines.

首次有机地将激光焊接能量传输效率这一重要的焊接参数以明确的物理意义引入数学模型中；通过谱线相对强度法计算推导出每一个焊接规范下小孔内等离子体对激光的平均吸收系数。

By adjusting the etch time and the concentration of acid in the process, different shapes of the tunnels can be obtained.

在栅极制作过程中通过改变酸液刻蚀的时间和浓度，可以腐蚀出不同形状的小孔。

M porous structure confirms transmission of body fluid of human body and ingrowths of mineral and fiber tissue, then made it firmer combine with around tissue of human body and the commutative pores was favourable for affusion of bioactive HA.

本实验采用东北大学陶瓷研究所研制成功的由Ti粉和Ni粉为主要原料，采用TiH_2和NH_4HCO_3作为造孔剂，通过粉末冶金方法制备的多孔NiTi合金，并采用真空灌注羟基磷灰石的方法取得的种植体的新材料，在添加TiH_2做为造孔剂的基础上在Ti：Ni原子比为50%：50%的试样中添加NH_4HCO_3做为第二种造孔剂后，试样中的气孔经检测是由100～500μm的大孔、1～50μm小孔和1μm以下的微孔组成，产生了合理的粗化表面并同时得到了固位良好的生物涂层。

They blow air through a small hole in the bottom to send smoke into the underground spaces where rats live.

他们捕鼠的传统方式是在一个陶罐里点上火，通过一个底部的小孔，将产生的烟吹进地底的老鼠洞内。

I drilled a small hole in the tank to release air as it compresses.

余钻穿一个小孔的坦克，因为它释放空气压缩。

The most high-precision machine-cut to about 0.003 mm, perforation of the smallest Hole diameter of 0.3 holes to play.

线割机最高精度达到0.003mm左右，穿孔机最小孔可打直径0.3小孔。

The model of the heat source for the quasi-steady state K-PAW, i.e. QPAW, can depict the character of the K-PAW process quite well, because it considers the "bugle-like" configuration of the Keyhole, and the "attenuation-feature" of heat flux distribution of the plasma arc along the direction of the work piece thickness.

准稳态焊接热源作用模式QPAW，考虑到了&喇叭&型小孔几何形状、等离子弧热流沿板厚的作用及其衰减特点，较为符合小孔等离子弧焊接工艺的实际情况。

Add an extra eyelet, insert the drawcord end into the eyelet and stitch the drawcord end so that it is hidden beneath the facing.

添加一个额外的小孔，插入小孔的drawcord结束缝合drawcord到底，这是隐藏下方面对的问题。

Although it was only off by 2.2 micrometres, this badly blurred the telescope's vision and made the scientists who had promised the world new images and science in exchange for $1.5 billion of public money the butt of jokes.

格瑞尼在2008年说伽利略观测到的星图其实是叫做艾利斑的衍射图像，艾利斑是指一束光通过一个小孔时得到的同心圆图像，就像一束星光通过一个小孔时呈现的图像。

And many times for some of us, there're some more holes, so from this, leaking comes, you know the rays in it, there is a reflection of a guru, and from another hole comes a reflection of the Avalokitesvara of four arms, woman, I don't know, whatever, driving fish.

有时候很多人，他们的蔽障之上会有更多的小孔，从这边泄漏出的光芒，投射出一个上师，从另外一个小孔呢，可能投射出的是观世音，可能是四臂的，可能是女相的，不知道，也许还骑着鱼。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
