发电机功率因数的过高、过低对机组有何影响？

Dear Michelle,

Why can't my daughter manage her life better? She is 17 and an honor student, but she seems to be wasting her life away with a boyfriend who is holding her back.

He consumes every waking minute of her precious time and smooth-talks her as well.

His goal is to get her to agree to go to the college of his choice, not her choice, and because his grades are lower, his choice will be limited.

I feel like I want to rescue her, but she pushes me away and shuts me out. She has only brought us pride and joy; and now this! Help!

A worried mother

Dear Mother of a 17-year-old Girl,

Hmmmmm. What's the matter with kids today? Remember that song from "Bye Bye Birdie"?

Well if you do not, let me fill you in about teenagers and their life-management skills. Do not expect too much too soon because at the ripe age of 17, life-management is not within their reach, nor should it be.

Life experience creates both the conditions and the skills for management, and if management went before experience, there would be little of it.

Your daughter is an honor student for good reasons. She is smart, studies with intelligence and you have given her good values.

When the time comes for her to apply for college, and she visits the ones that are specifically designed for students at the top of their grade, she will most likely break away from her boyfriend's influence.

It is rare for an honor student to change the path of their academic career for puppy love. That being said, there might be some adolescent wisdom in her behavior after all.

Perhaps she is choosing to worry you, her parents, for unconscious reasons. Being such a good girl and being a steady source of joy might have become a bit too much for her.

Let your daughter have her own private moment of 11th grade rebellion. She deserves a break from perfection.

Michelle

中微子是宇宙间的“隐身人”，是一种非常小的基本粒子，几乎不与任何物质发生作用，因此尽管每秒有上万亿个中微子穿过我们的身体，但我们很难发现它的踪影。早在1930年著名物理学家泡利（1945年诺贝尔物理学奖获得者〉就预言了这种神秘粒子的存在，但科学家用了25年的时间才证实了这一预言。这主要体现了（）
