山东省济南妇幼医院门诊在那里SolarCity presents How oil power gets to youSolarCity巨献:石油能源到你家First a bunch of green organisms absorb the sun#39;s energy最早有一群古老的有机体吸收了太阳的能量just a few short hundreds of millions of years later people pressured them into oil受压短短几亿年后变成了石油next the old time ship get into the ground and shipped thousands of miles to refinery接着从地下被钻出之后,运了好几英里到达炼油厂where the oil freshly distilled in practicum to become gasoline经过蒸馏之后变成汽油and diesel sweating garlic sauce for 90 minutes, just kidding接着当做酱汁来淋煮章鱼九十分钟,我开玩笑的。from there the gasoline was pumped in massive trucks,接着这些汽油被很大的需要汽油的汽车which is even more gasoline to drive the other gasoline thousands of miles载到好几英里远之外,so the guy can pumped it back into the ground再放回地下保存just in time another guy to pump it out of the ground into his car接着又从地底下取出来,加到汽车里面and this is how solar power gets to you.而太阳能的来源就是这么简单SolarCity, power forever!SolarCity,永生能源! Article/201701/486776济南去哪里做人流好 Another unit used to measure levels另一个衡量运动强度的单位是METof activity is the MET. MET stands forMET的意思是代谢当量任务metabolic equivalent task. All living being所有生物都需要能量require energy to support the basic functions来维持人体的基本机能of the body hence there is a constant energy cost所以这些代谢过程都要associated with these metabolic processes.持续不断地消耗能量This is called the resting metabolic rate.这叫做静息代谢率Physical activity adds to the energy costs of除了人体保持静止需要的能量the body beyond those required to maintain运动会消耗人体更多的能量the body at rest. Energy expenditure varies能量消耗随着运动种类with type of activity and intensity and the MET和剧烈程度的不同而变化measures this. Many studies have been doneMET正是衡量能量消耗多少的单位to determine energy cost of different activities很多研究发现,通过检测氧气的消耗by monitoring the oxygen consumed and和计算运动的平均耗氧量calculating the average oxygen it takes可以确切得知不同运动的to do that activity. Comparing that average oxygen能量消耗是多少,通过比较intake to resting oxygen uptake is how METs平均耗氧量和静息耗氧量而得出的MET值are determined. One MET is the energy expended一个MET是静止时消耗的能量at rest. Two METs designates the energy expended两个MET指的是静止时twice that at rest and so on. The higher the MET消耗能量的2倍 MET值越高the more intense the activity.运动就越剧烈The chart gives examples of activities这个图标提供了各种运动and their associated METs. Very light activities和它们的MET值,非常轻微运动such as standing, ing, talking on the telephone,例如站立,阅读,打电话studying, sitting in class and note taking all have学习,坐在教室上课,记笔记等a MET from 1.3 to 1.8. Light activities haveMET值在1.3到1.8之间a MET of 2. Activities in this category轻度运动的MET值是2are playing a musical instrument, gardening,轻微运动包括弹奏乐器,做园艺light office work such as filing, walking整理文件等轻度办公室工作at a slow pace and light use of hand tools.慢走,以及手动工具的少量使用Moderately vigorous activities have中度剧烈运动的MET值是a MET of 3.5 to 4 and include such activities3.4到4,包括举重such as weight lifting, leisurely kayaking, walking休闲皮艇运动,在办公室中行走in an office and golfing without carrying the clubs.不携带球棒打高尔夫球等Vigorous activities have METS from 6 to 16剧烈运动的MET值在6到16之间and include things from slow jogging at包括消耗6个MET值的a 13 minute mile with a MET of 613分钟慢跑,和消耗16个MET值的to running a 6 minute mile with a MET of 16.6分钟慢跑Physical activity and obesity are closely related.运动和肥胖有着密切的关系Individuals who are inactive tend不爱运动的人to have a higher percent body fat肥胖的概率更高and may be obese. Obesity has been found可能导致过度肥胖,研究发现to be a significant risk factor for cancer.肥胖是癌症的重要诱因The American Cancer Society estimated2005年,美国癌症研究协会估测in 2005 that 90,000 Americans die annually每年有90000美国人from cancer primarily because of being overweight.因为过度肥胖而死于癌症This accounted for 14% of cancer in men上述人群占男性癌症患者的14%and 20% of cancer in women. In women占女性癌症患者的20%obesity leads to higher risks of breast, uterine,女性过度肥胖容易导致乳腺癌,子宫癌cervical, pancreatic, esophageal, renal and子宫颈癌,胰腺癌,食道癌,肾癌gall bladder cancers. And in men obesity以及胆囊癌的高发病率,男性过度肥胖is linked to higher risk for liver, pancreatic,会带来肝癌,胰腺癌,结肠癌colorectal, stomach and gall bladder cancers.胃癌以及胆囊癌的高发病率 Article/201508/394701中国人民解放军456医院月经不调

济南紫荆花医院彩超检查好吗 The key difference of course is that a sunspot#39;s最关键的不同点在于太阳黑子an awful lot bigger and so the total energy,大得多,所以太阳磁场内or the amount of energy in the magnetic field所含的总能量大得惊人on the sun is enormous but the field strength但是任一部位的磁场强度at any given locationis something you can hold in your hand.和一般磁铁差不多Sun spots are just the visible effect of magnetic fields太阳黑子的形成是因为磁场强度过强so strong that they can prevent the heat以致阻挡热能and light rising from the sun#39;s interior.及光线离开太阳内部With the right viewing equipment只要用合适的观测器材you can even see the magnetic fields.就能看到磁场Magnetic loops arch off the surface,磁力圈在太阳表面形成拱形like iron filings around a bar magnet they#39;re shapes如同磁铁棒周围的铁屑are mapped out by plasma heated to a million degrees.一百万度的高热电浆勾勒出它们的形状The largest are 200,000 kilometres high.最大的磁力圈有20万公里高And they are packed full of unstable energy.饱含不稳定能量When you add up the total energy content要是把磁力圈的能量加总起来in these loops it comes out to roughly 10 to the 21 joules约可得到10的21次方焦耳of energy and that#39;s roughly ten times the annual energy约相当于美国年度消耗consumption of the united states.能量的十倍Of course we can see thousands of them at any one time.我们不论何时都能看到数以千计的磁力圈The loops are caused by the twisting磁力圈是因太阳of the sun#39;s basic magnetic field.基本磁场的扭曲所致Because the sun rotates faster at the equator因为太阳的赤道旋转速度比两极快than at the poles it drags the field lines with it所以磁力线因受到拉扯stretching and twisting them like elastic bands.而像橡皮筋般地拉长、扭曲As the solar cycle goes on the fields get more随着太阳周期的进展and more twisted and break through the surface.磁场扭曲得越来越严重并突破表面Until at Solar Max the whole sun is covered到了太阳活动极大期时,整个太阳覆满了in loops stretched to breaking point.伸展至断裂点的磁力圈Solar flares are what happen若拉力过大,导致磁力圈断裂when the strain gets too much and the loops snap.就会产生太阳闪焰Basically all that energy comes out of the catastrophic基本上此时磁场会一股脑地release of energy that#39;s been stored in the magnetic fields.释放其储存的能量So like if you wind up an elastic band too much,好比说把橡皮筋拉得太紧if you let it go with your fingers手一放开that elastic band flies across the room.就会飞到房间的另一头When the energy bound within sunspots is released,被局限在太阳黑子内的能量一旦释放billions of tonnes of plasma are fired数十亿噸的电浆便会far into space at huge speeds.高速喷向太空And sometimes they are aimed straight for the Earth.有时它们朝着地球直扑而来The flares fly through space for 2 days.闪焰在太空中前进两天When they reach us它们抵达地球时the earth#39;s own magnetic field deflects most of the blow.大半会因地球的磁场而转向But it is the impact on the magnetic field但闪焰对磁场造成的冲击which causes the effects on Earth.影响了地球It#39;s called Space weather这种现象叫做太空天气and the best of its effects are magical.而且有时候会产生如梦似幻的结果 Article/201504/369756山东师范大学校医院妇科咨询济南七院收费贵吗
