Saving the date

1 Every day I anxiously wait for you to get to class. I can't wait for us to smile at each other and say good morning. When you arrive only seconds before the lecture commences, I'm indifferent to anything but your arrival. Instead of reviewing my lesson, I anticipate your footsteps and listen for your voice. Today is one of your late days, but I don't mind because after a month of denying the impulse to ask you out, today I'm feeling bold. Today I'm inclined to act.

2 I know dating has changed dramatically in recent years, and for many women, asking men out isn't daring. But because of my traditional upbringing, the simple notion of asking you out seems abnormal. Growing up, I heard the clear message: Men must take the initiative and make contact. They should call, ask and pay for the date. However, during my years at the university, I've learned otherwise. Many of my women friends have put a spark in their social lives by taking the initiative with men. My girlfriends reckon that it's essential for women to participate more actively in the dating process. "I can't be idle and wait," my former roommate once said. "Hard as it is, if I want to date, I have to ask guys out!"

3 More women are taking the initiative and invite men out, and many men say they view this new phenomenon with approval. They are relieved that dating no longer solely depends on their willingness and courage to take the first step. Then why am I so nervous?

4 I tell myself to relax since dating is more casual today. A college date means anything from studying together to simply having leisure time together like watching a film. Most of my peers prefer casual dating because it's cheaper and comfortable. Students have fewer anxiety attacks when they ask somebody to play tennis than when they plan a formal occasion.

5 As an added bonus, casual dating also encourages people to forge healthy friendships prior to starting romantic relationships. Young people can relax and get to know each other more easily this way. For example, my roommate and her boyfriend were friends for four months before their chemistry clicked. They went out often with a bunch of mutual friends. They alternated paying the dinner check. "He was like any other friend," my roommate said laughing. Another friend of mine believes casual dating improves people's social lives, allowing them to circulate in wider social circles. When she wants to let a guy know she is interested, she'll say, "Hey, let's go get a yogurt." or "How about a cup of tea?"

6 Who pays for it? It's not as easy as it used to be because the traditional rules of courtship are undergoing major changes. Preliminary statistics also affirm this. A plurality of young men say women should chip in and help pay after a few dates. An almost equal percentage of women offer to pay for themselves, even on a first date. But widespread confusion still exists. The new rules have yet to be clarified.

7 My own past dates have taught me some things. Either "going Dutch" or allowing my date to pay can be a definite challenge. One date whipped out his wallet on our first date before I could suggest otherwise. During an after-dinner walk, he proceeded to tell me he was romantically interested in me. After I explained I was more interested in friendship, he seemed unhappy. He explained that since I'd accepted his paying for my dinner, he'd assumed I was interested in romance. He seemed angry with himself for treating me. I regretted allowing him to.

8 Another date frowned when I hastily opened my purse, pulled out my wallet, and offered to go Dutch. I asked politely, "How much do I owe you?" He said, "Uh, uh, you really don't owe me anything, but if you insist …" He looked exceedingly embarrassed. To him, my gesture of offering to pay had conveyed a message of rejection.

9 Everyone seems confused as they try to clarify the new rules of dating. Who should ask whom out? Who should pay and when? So, while I do think dressing up and going out on traditional, formal dates is a blast, I thrive on casual dating because it has brought a valuable dimension to my social life. With casual dating, there's less pressure and more equality. I can give roses as well as receive them! Casual dating is worthwhile because it works.

10 So here I am, waiting. No magic formula guarantees he will say "yes". I just have to relax, be myself and ask him out in a no-nonsense manner.

11 He finally arrives. Sliding into his desk, he pats my shoulder and asks, "Hi, what's up?"

12 "Good morning," I answer cautiously. With a knot in the pit of my stomach, I conquer my fear and ask, "Hey, how about lunch after class on Friday?"

13 "You mean after the midterm?" he says with barely concealed enthusiasm. "I'd love to go to lunch with you."

14 Thrilled and smiling broadly, I confirm, "Well then, we'll save the date!" "Yes, we will!" he replies cheerfully.

六、电路与电子学第五版答案?

所以这个的答案呢,哈哈哈哈

七、电机与变压器绪论电子课件

电机与变压器是电力系统中的重要组成部分。电机将电能转变为机械能,而变压器则用于调节电压。在这篇文章中,我们将介绍电机与变压器的基础知识,并探讨它们在电力系统中的应用。

电机

电机是将电能转换为机械能的设备。它是由电磁铁和旋转部分组成的。当电流通过电磁铁时,产生的磁力将旋转部分推动起来,从而实现机械运动。

电机分为直流电机和交流电机。直流电机是最早发明的电机类型,它通过直流电流产生磁力。交流电机则通过交流电流产生磁力。交流电机的种类较多,包括感应电机、同步电机和永磁电机等。

感应电机是最常见的交流电机类型。它通过电磁感应原理工作。当定子上的电流发生变化时,会在转子中产生感应电流,从而产生转矩。感应电机通常用于家用电器、工业设备等领域。

同步电机是另一种常见的交流电机。它的转速与供电频率保持同步。同步电机通常用于发电机组、电力系统调节等领域。

永磁电机是利用永磁体的磁力产生转矩的电机。由于永磁体具有较强的磁力,永磁电机具有高效率和较高的功率密度。它广泛应用于电动汽车、工业自动化等领域。

变压器

变压器是用于调节电压的装置。它由两个或多个线圈绕组组成,通过电磁感应原理实现电能的转换。

变压器主要包括输入绕组(也称为原级)和输出绕组(也称为次级)。当输入绕组中的电流发生变化时,会在输出绕组中产生对应的电流变化。通过改变输入绕组和输出绕组的绕组数和比例,可以实现电压的升高或降低。

变压器广泛应用于电力系统中。在电网中,变压器用于将高电压传输的电能转换为适合用户使用的低电压。变压器还用于电力系统的输电和配电过程中,起到电压调节和电能传输的作用。

电机与变压器的应用

电机和变压器在各个领域都有重要的应用。

在工业领域,电机被广泛用于驱动各种机械设备,如风机、泵、压缩机等。电机的效率和运行稳定性对生产过程至关重要。通过选用合适的电机型号和控制方法,可以提高生产效率和节约能源。

在交通运输领域,电机被广泛应用于电动汽车、电动自行车等交通工具。电动交通工具具有环保、低噪音等优点,对解决城市交通拥堵和环境污染问题具有重要意义。

在电力系统中,变压器是不可或缺的设备。变压器用于实现电能的传输、分配和调节。电力系统中的变压器数量庞大,各种类型的变压器在电力系统中起到关键的作用。

总之,电机与变压器是电力系统中不可或缺的组成部分。了解电机与变压器的基本原理和应用是每个电力工程师都应具备的知识。通过合理应用电机与变压器,可以提高电力系统的效率和稳定性,实现可持续发展。
