If you use the nutrition cream, DIY nutrition and so on, can be used to mask a little bit thicker paper, that to strengthen the gas-tight, and secondly, is the usual type of doctrinal and nutrition, can help mask paper adhesive infiltration; If you use the the real flower water, Skin liquid and so on, may mask some of the appropriate use thin paper, because the load of paper through the mask, water molecules penetrate the stratum corneum is essentially direct, the replenishment effect is very clear.

如果使用营养霜、DIY营养液等，可使用稍微厚一点的面膜纸，这一来是加强气密，二来是通常这类营养品较浓，面膜纸有助粘附渗透；如果使用真正的花水、柔肤液等，则可适当选用薄一些的面膜纸，因为通过面膜纸的承载，水分子基本上是直接渗透角质层的，补水效果是十分明显的。

Firstly, the theory and knowledge of sparking and burning are briefly introduced. The holistic project of this experiment is designed aiming to the experiment motive. And then the micro-process technique on silicon is chosen. According to the technique, the structure and size of the micro chamber, the spark device, the gas-fired channels are designed. The mask of lithography is produced based on the design. At last, the whole burning room is produced by the techniques of photolithography, deposition, dry etching, wet etching, lift off, etc.

本文首先介绍了点火燃烧的有关原理和基本知识，然后根据提出的实验研究目标，确定了微小空间内点火特性实验总体方案，之后结合拟采用的硅微加工工艺设计确定了微燃烧室、放电点火装置、燃气通道等各部件的结构尺寸，并最终得到光刻用掩膜版图形，最后分别采用光刻、淀积、干法刻蚀、湿法刻蚀、剥离等硅微加工技术完成了实验用微燃烧室的制作。

Methods: Twenty ASA Ⅱ~Ⅲ patients aged 28~69 years were randomly divided into 2 groups:(1)3-mins group (n=10).(2)8 deep breathings group (8DB). Arterial blood samples were drawn with a fraction of inspired oxygen of 0.21for arterial blood gas analysis. Before induction of anesthesia, patients in 3 mills group were asked to breathe normally for 3 mins during which 100% oxygen at 10 L/min through an anesthesia mask attached to a circle system with soda lime was adopted, and adjustable pressure limiting valve was kept open.
