他们发现米勒甚至没有报告最好的实验结果——沐浴在类似火山蒸汽的烧瓶中的结果。

Atomic force microscope was employed to observe the surface morphology of nanostructured silver films and the grain size of silver particles was analyzed. EDX was used to analyze the surface elemental distribution. The results showed that the antibacterial properties were improved as the film thickness increased.

采用振荡烧瓶法测试样品的抗菌性能，利用原子力显微镜分析纳米结构银薄膜表面形态及粒径，应用EDX分析薄膜表面的元素分布。

Procedure In a 1-l. round-bottomed flask are placed 250 cc. of glacial acetic acid, 15 g.

程序 在1升。圆桌会议触底烧瓶置于250毫升。

In a round-bottomed 2 L flask equipped with a magnetic stirrer and placed under an inert atmosphere, there was added 750 mL anhydrous THF, containing 30 g LAH.

将磁力搅拌器放入一个2L的圆底烧瓶，放置在惰性气体环境下。加入750ml无水THF，包括30gLHA。

Apparatus— Use a 500-mL glass flask A connected by means of a trap B to a reflux condenser C by ground glass joints.

装置---使用一个与500ml的玻璃烧瓶A，与水分测定管B连接，使用磨口玻璃接头与回流冷凝器C连接

Test Preparation Transfer about 2 g of the substance under test, accurately weighed, to a glass-stoppered, 250-mL conical flask, add 20 mL of a mixture of equal volumes of nitric acid and sulfuric acid, attach a suitable condenser, reflux the mixture for 1 hour, cool, cautiously dilute with water, and boil until fumes of nitrous acid no longer are noticeable.

Test准备 Transfer大约2 g在测试之下的物质，准确地被称，对玻璃防止， 250ml conical烧瓶，增加硝酸的相等的容量混合物的20 mL，并且硫酸，附有一适当的 condenser，循环加热混合物1个小时，凉快，慎重地稀释与直到亚硝酸发烟的水和煮沸 acid不再是引人注目的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
