羽绒120万一吨,本款鸭绒耗用100-122克.请问填充这款羽绒服成本是多少元?

凉干后揉一揉就好

一般都说三合一的,就是外套+一个内胆,合起来是一件,分开之后又是两件,所以叫3合一,你这个四合一可能是还有个羽绒吧,我没看见不太清楚,还有关于压胶
三层压胶一般是防水系数最高的,但是质地比较硬,平时穿着不一定舒适
两层压胶衣服比较柔软,防水系数相对较弱
还有两层半压胶,就是介于两者之间,很好分辨,衣服的里面有一层衬底,是为了防止摩擦把防水层磨破的,现在非专业冲锋衣大多是两层半压胶,因为工艺相对简单

填空：1.李白诗中与“潮平两岸阔,风正一帆悬”有异曲同工之妙的一句是：（两岸青山相对出,孤帆一片日边来）.
2.某商场购进一批羽绒衣,可暖冬天气持续了半个月,于是资金周转不灵.商场大伤脑筋,忽然传来气温下降,几日内有雪的消息,这正如陆游在《游山西村》中所说的：（山重水复疑无路,柳暗花明又一村）.
3.好友离别,有人用王维的“劝君更尽一杯酒,西出阳关无故人”相赠,这略显伤感,请你用《送杜少府之任蜀州》中的“海内存知己,天涯若比邻”来鼓励和安慰朋友.
补全诗句：1.市桥官柳细,（江路野梅香）.
2.（晴虹桥影出）,秋雁橹声来.
3.波光柳色碧溟潆,（曲渚斜桥画舸通）.
4.（唯有别时今不忘）,暮烟秋雨过枫桥.
赏析：枫桥夜泊

月落乌啼霜满天,江枫渔火对愁眠.
姑苏城外寒山寺,夜半钟声到客船.
1.全诗表达了作者一种什么样的情怀?
（表达了诗人旅途中孤寂忧愁、辗转难眠的思乡情怀）
2.作者是如何表现这一情怀的?
（ 用“月落”、“乌啼”、“霜满天”、“江枫”、“渔火”等物,及钟声传到船上的情景,从视觉和听觉勾勒出诗人思乡难眠的愁情）.

0.8a-40=500+500x20%
0.8a=640
a=800

将完全干透的羽绒服铺展,然后用小棍或竹片轻轻拍打里外二面,直至羽绒服完全膨松,就可以了.

（1）题意可知，所探究的两种保温材料厚度、大小均相等，热水及容器相同，在材料不同的情况下，通过实验数据可以看出，包羽绒的瓶内温降低的慢，降低到相同温度时所用的时间较长，因此保温性能较好的是羽绒；
（2）从数据可得，经过160min后，包羽绒的瓶中的水由80℃降到10℃，温度降低了70℃，根据放热公式Q=cm（t ₀ -t）得：
Q=4.2×10 ³ J/（kg•℃）×1.5kg×70℃=4.41×10 ⁵ J；
（3）根据每10min热水温度的变化可知，热水与外界的温差越大时，放热越快．
故答案为：（1）羽绒；
（2）4.41×10 ⁵ J；
（3）热水与外界温差越大时，放热速度越快（或热水放热先快后慢）．

这,这,这让老夫如何是好.

设买一件羽绒背心x元,买一件羽绒服y元,由题意得
x+y=10
50x+300y=2000
解得x=4 y=6
答：羽绒背心买了4件,羽绒服买了6件.
（提个意见：下次最好能有点悬赏）

肥皂是碱性的,洗衣粉是酸性的 我是搞化学的 手上碰到酸性溶液的时候师傅告诉我用肥皂洗,可以中和 洗衣粉洗就不行

解题思路：（1）设每次降价的百分率是x，则第一次降价后的价格为1000（1-x）元，第二次降价后的价格为1000（1-x）²，根据两次降价后的价格是810元建立方程，求出其解即可；
（2）分别求出第一次降价金额与第二次降价金额，再将它们相减即可．

（1）设每次降价的百分率为x，由题意，得
1000（1-x）²=810，
解得x₁=0.1=10%，x₂=1.9=190%（不合题意，舍去）．
答：每次降价的百分率为10%；

（2）第一次降价金额：1000×10%=100元，
第二次降价金额：900×10%=90元，
第一次降价金额比第二次降价金额多：100-90=10元．
答：第一次降价金额比第二次降价金额多10元．

点评：
本题考点： 一元二次方程的应用．

考点点评： 本题考查了运用降低率问题解决实际问题的运用，列一元二次方程解实际问题的运用，解答本题的关键是找到等量关系建立方程．

充绒量：充绒量不是衡量羽绒品质的指标,它是指一件羽绒被填充的全部羽绒的重量.
含绒量：含绒量是羽绒里面绒的比例,一般以百分数的形式表示.户外羽绒被的含绒量一般在80％以上,这个数据表面其中绒的含量是80％,羽则占到20％.
我们所说的羽绒,都是指绒与其他成分（如：飞丝,羽丝,小羽毛）的混合物,并不是纯粹意义上的羽绒.

（1）羊毛和涤纶类：抽丝点燃
产生的黑色颗粒可以碾成末的是羊毛类天然的
有硬结的是涤纶非天然类的
（2）化肥：灼烧有大量白烟的：(NH3)2 SO4和NH3CL.有白光的是NH3NO3,别的一般无现象,碳酸氢铵有氨味可以直接区分.磷矿粉为灰白色粉末状,其他是固体.(NH3)2 SO4和NH3CL可以用硝酸钡和硝酸银区分

800÷九分之八等于900,所以一共要加工900件900减800等于100

填进衣服的 就直接用 down就可以了
你买羽绒衣就看到了

王小臭,给分!
What is down?
Down is long in goose,duck's abdomen,into a flower-shaped hair reed,into the sheet is called feathers.Because down is an animal protein fiber than cotton (plant cellulose) insulation of a high ball down the fiber and the clouds of millions of small triangular holes,can change with temperature contraction and expansion,resulting in temperature regulation function can be absorbed distribute the flow of body heat,isolated from the outside cold air invasion.
In cotton,wool,silk and natural warmth of down four materials,the thermal performance down the best.France,Germany,known as research institutions to the best of down bedding.China's large medical scientist Li Shi Zhen in the "Compendium of Materia Medica" also mentioned:"goose belly hair to clothing selection was Xu,soft,and the new cold in nature,in particular,may surprise solution infants pain." Explanation with a modern point of view,down The health function is unique because of the gentle warmth of down and the good performance of moisture divergence determined.Degree from the thermal point of view,France's scientific research institutions to publish the findings that:the world does not have any thermal material over the thermal properties of down because down is the star flower-like structure,cashmere yarn of each are available under the magnifying glass see that is was Yulin Zhuang,with numerous small pores,implied a large number of still air,because the minimum conductivity of air,forming a good warmth of down,plus another full flexibility down to 50% cashmere The down test,it's light and fluffy cotton degree equivalent to 2.5 times,2.2 times that of wool,it is not only a gentle warm down,and the sense of touch is also very good skin,
In addition,warm down also has other materials do not have the good performance of moisture divergence.It is measured continuously in sleep the body sweat out divergence,an adult night sweat emitted about 100 grams,down to the continuous absorption and emission release of human sweat,the body does not feel wet and hot.In summary,because the specific down the gentle warmth,moisture divergence of good performance,so cover duvet will feel warm and comfortable sleep,nor oppressive,is normal blood pressure,central nervous system to be stable,fast access to sweet dreams,it also has the beauty to good effect,"under a beautiful duvet" It is for this reason.
I Love U!
