因此，我们认为可以通过利用SiO_2的阻挡作用，结合机械刻槽和丝网印刷，通过一次扩散宋代替通常的分两次进行扩散宋制作"选择性发射极"的方法。

In silicon deep reactive ion etching using inductively coupled plasma etcher,a narrow trench with a width of several micrometers usually shows positively tapered profile, which means that the width of the etched trench decreases with the progress of etching depth.

利用自感应耦合等离子蚀刻机进行硅深层反应离子刻蚀，得到了几微米宽的狭槽，其轮廓通常为正锥形，即蚀刻槽的宽度随着蚀刻深度的增大而减小。

Due to specific geometry of the fluted helix surface, sub-cooled boiling can be realized on the interface of the rising film.

由于刻槽管特殊的几何结构，液膜表面能实现欠热蒸发和过冷沸腾。

Another display shows the 1914 Yuan Shih Kai Dollar (Y329 type) with three different edges – with ordinary reeding, with a "Greek border" or alternating "T" design on the edge, and with a sort of "herring bone" design edge, in which curved, raised bars alternate with raised boxes.

另一个被展出来民国三年袁世凯头像壹圆（Y329 type，不知是啥，可能是PCGS的标识吧）也有三种不同的齿边，一种也是普通的刻槽直齿边，一种呢，是被称作"希腊边"的样式，也就是字母"T"上下交叉排列设计的的一种齿边样式②，第三种齿边样式有点类似於鲱鱼的骨头，末端呈弯曲的样子，凸起阴刻的线条连接著这些凸起末端弯曲的像隔栅线③。

Monochamus alternatus adults' habits of feeding, oviposition and biting nidi were observed in Nanyue Scenic Spot, Hunan Province between June and August of 2001, 2002 and 2003. The results indicated that the adults caused damage not only by feeding but also by biting nidi in the healthy pines.

2001-2003年6-8月对南岳景区松墨天牛成虫的取食、产卵、咬刻槽等习性进行了观察研究，结果表明，松墨天牛成虫除取食危害外，在健康松树上咬筑刻槽也会对寄主造成危害。

Compared with the susceptor without groove, the temperature distribution in the wafer on this susceptor is improved obviously.

与没有刻槽的基座相比，这种刻槽优化后的基座，其对应衬底温度的均匀性显著提高。

In addition, we discovered the law of heat transfer in this susceptor by the analysis of the temperature in it changing with the heating time.

另外，通过对其温度随加热时间变化的分析，发现刻槽基座的热输运规律，即所刻的槽改变了基座中感应产生热量的热传导方向，衬底的热量是由槽上下基座部分传递而来的，且随时间的增大，基座的温度趋于恒定，衬底的温度趋于均匀，这有利于提高生长薄膜的质量。

In this paper, incising blasting engineering in granite row stone exploitation as the research object, in order to analyze the fracturing mechanism principles of V-shaped notch blasting and the influence of blasting parameter changing to V-shaped notch blasting effect, the elastic-plastic isotropy and multi-notched hole of plane strain model is set up.
