把这一句，留给此刻的你
By allowing the positive ions to pass through an electric field and thus giving them a certain velocity, it is possible to distinguish them from the neutral, stationary atoms.
通过让正离子穿过电场，从而使它们具有一定的速度，就有可能把它们与中性的、静止的原子区别开来。
A LITTLE ENCOURAGEMENT
给此刻的你，一点向前的力量。
关于学习、善意与成长，读一句，再想一想。
When you give, give from the place of the heart because it is the right thing to do, not the easy thing to do.
当你付出时，要发自内心地付出，因为这是正确的事情，而不是容易的事情。
We all have a natural instinct to protect children from harm. It's never fun to see a child hurt, even if it's just a scraped knee. But on the other hand, children need to take on physical challenges to learn and grow, and scraped knees and other bumps and bruises teach them valuable lessons about their own limits.
我们都有保护儿童免受伤害的自然本能。看到孩子受伤从来都不是一件有趣的事，即使只是擦伤了膝盖。但另一方面，孩子们需要接受身体上的挑战来学习和成长，擦伤膝盖和其他磕碰和瘀伤教会了他们关于自身极限的宝贵经验。
Success follows those who champion a cause greater than themselves.
成功来自那些为比自己更伟大的事业奋斗的人。
