怎样理解肺的宣发、肃降?

答案

参考答案:

肺的宣发与肃降运动,是由肺气的升降运动来实现的。肺气的宣发运动,能向上向外布散气与津液,主要体现在以下三个方面:一是呼出体内浊气;二是将脾所转输来的津液和部分水谷精微上输头面诸窍,外达于全身皮毛肌腠;三是宣发卫气于皮毛肌腠,以温分肉,充皮肤,肥腠理,司开阖,将代谢后的津液化为汗液,并调节其排泄。

肺气的肃降运动,能向内向下布散气和津液,主要体现在以下三个方面:一是吸入自然界之清气,并将吸入之清气与谷气相融合而成的宗气向下布散至脐下,以资元气;二是将脾转输至肺的津液及部分水谷精微向下向内布散于其他脏腑以濡润之;三是将脏腑代谢后产生的浊液下输于肾或膀胱,成为尿液生成之源。

30th September

Dear Jayne,  

  How are you? I hope everything is getting on well with you.  

  I returned to my home on the morning of September 28th, at 2 am. I am so

sorry for not calling you as soon as I came back home.  

  I have been allowed to stay at home for two days (from September 29th to

September 30th) to have a rest. The Chinese National Day is on October 1st. We

have a seven-day off for National Day holiday.  I will stay at home to have a

good rest.  

  Thank you for your help.  I miss you and your kindness.  I miss the climate

in England in summer, too.  It is neither too hot nor too cold.  Now it is still very

hot in most parts of China, especially in the south of China, for example, in

Guangzhou.  The sun seems to dry up everything. We have to use air conditioner

to make the air cool enough so that we can have a good sleep at night.  

  I will continue my work on October 8th.  After I start my work, it will be

too busy for me to do anything that I want to do, but I will try my best to get in

touch with you.  

  Best wishes.                                          

                            Yours sincerely,                                                                          

                                     Sunny
