结论:穿耳孔宜用激光或经严格消毒后的注射器针头,配戴纯金或银耳饰。
Grounding on the condition of force acting on the fluid in the syringe needle, a simple evaluation model is attained for the flow rate and the dot volume.针对针尖胶体的受力情况,建立了一个简单的流量或胶点体积估计模型。
I have a special habit, I always look at the syringe needle stat into my skin. But when I lay down, I can see the needles, it makes me a little uncomfortable and nervous.我有一个习惯就是抽血扎针一定要看着针头戳进去,但是我躺下了就看不见了,所以这让我感觉有一点不适应,有一点紧张。
