Thus it is conceived that the bit can be developed by coupling with micro convex non-smooth material (diamond) and macro smooth pit, which may lead to the high efficiency and strong wear.
于是想到将微观凸包非光滑(金刚石)和宏观凹坑非光滑复合来设计钻头，如此可以实现高效耐磨的目的。
After you have made the pit of the petal the way you want it, now it is time to erase the edges to make this a bit more refined.
在你做出了花瓣上的凹坑部分以后，现在你可以擦掉边缘部分以让它更精致一些，我使用不透明度为12，大小为20的笔刷。
In the first part of the race, I felt comfortable on the softer tyre, while I struggled a bit more on the harder one, especially after the pit stop.
在第一部分的比赛，我对软胎感觉还是很适应，过了一会我对硬胎还是有些不适应了特别是在进站之后。
I am a bit disappointed but I made mistakes on my second lap in Q3 and I have to accept that: I didn't go into the final corner before the pit straight quite right and lost a lot of speed.
我有点失望，但我在第三节排位赛第二圈时犯了错，我必须接受这个结果：在维修站的前最后一个弯角我没有走好，因此损失了一些时间。
Drilling parameters typically include flow rate, pump pressure, standpipe pressure (SPP), pipe rotation (RPM), weight on bit (WOB), rate of penetration (ROP) and pit volume (PVT).
流量、泵压、钻压以及机械钻速等常用钻井参数还可用于监测井涌和泥浆漏失。
In the first stop I was lucky I saw the arrows, so I came to the pit with a little bit of doubt if the guys were there or not and Ron was telling me the radio was off.
在第一次停站时我很幸运地注意到了箭头的提示，所以我进入了维修站，不过当时我有些担心他们是否在那儿准备好了。后来Ron （Dennis） 告诉我无线电发生了故障。
