目前一项研究表明：吃饭时注意力分散，可能掩盖我们吃饱的事实。此外还发现，the caloric fallout of not paying attention to what we’re eating doesn’t necessarily end when a meal is over(?)。
来自英国的Rose Cooper和她的同事，集合了男、女各22人进行实验。每个人单独用餐，连续收到九小份食物。有奶酪曲奇、薯片、胡萝卜、樱桃、西红柿和香肠卷或三明治。
因为测试目的是观察注意力分散对吃饱的潜在影响，研究人员随机在一半的参与者吃东西时，放置一个计算机—以在“扑克”游戏中尽可能获胜。其他人则被告知重点要放在其膳食的感官品质上。
根据指示，参与者吃完了所有的食物。然而，在午餐时玩电脑游戏的人发现，与另一组相比，自己没有吃饱。在近一个小时后，游戏玩家在得到各人所希望的甜点后（称为口味测试），吞下两倍的饼干。英国科学家目前在美国临床营养学二月的杂志上，公布了调查结果。
真正的问题是，为什么要吃东西分心会影响吃零食。科学家们说，看起来记忆在我们吃什么和吃多少可以满足上同我们开了个玩笑。
有趣的是，八年前斯德哥尔摩的Huddinge大学的Britta Barkeling和她的同事也报告了相似的结果。18位超重受试者被蒙上眼睛，只吃午餐。与可以看到食物的人相比，这些人消耗的热量只有四分之三。甚至几个小时之后，他们仍说和看到自己的盘子爆满吃饭时一样饱。
在黑暗餐厅进餐当然是不现实的。有时，我们吃东西并不需要绝对关注。但有相当数据表明，无目的地海吃是一种资源浪费，增加对我们腰围的风险和对健康的昂贵威胁。

Aluminum alloy and magnesium alloy comparison
Magnesium Abbreviations: Mg, the chemical code: Mg; magnesium metal body belong to cubic lattice, can bear the limited deformation.
Scientists in Russia in 1869 Mendeleev's first periodic table in chemistry at the metal sodium (Na) elements and metals (AL) elements
Between, from the periodic table shows that all three belong to the same metal, but the elemental characteristics of a great difference of easy understanding, the lively nature of the metal: Na> Mg> AL; from easy view oxidizing Na> Mg> AL. Lively experiment metal case, cut a small fast sodium metal on the water as soon as we can see a fireball at the water on fast-moving, the reality is that Na and water at room temperature on the occurrence of oxidation reaction to generate sodium hydroxide and hydrogen. Therefore vulnerable to oxidation from the perspective of Na> Mg> AL.
Concept Note: The aluminum alloy is usually described by more than 95% content of aluminum, are from other parts of magnesium and other trace elements in the alloy as the alloy composition; that magnesium alloy is from about 90% of the magnesium content is about 10% of the composition of aluminum and Zinc alloy known as magnesium alloy. Magnesium alloy and aluminum alloy main parameters as follows:
Magnesium Alloy Aluminum Alloy
Proportion of the density of 1.79 g/cm3 2.74 g/cm3
Tensile strength 220 MPa 320 MPa
RB anti-fatigue strength of 60 MPa 145 MPa
Elastic modulus of 45GPa 72GPa
1; proportion density Description: equal volume of magnesium alloy under the conditions of the quality of light than the aluminum alloy, which are the advantages of magnesium alloys.
2; tensile strength Description: the same volume of material made of magnesium alloy frame strength than aluminum alloy frame to achieve the strength to be increased in thickness and tube material by, so from the perspective of the weight of aluminum alloy to compare with any magnesium alloy advantage.
3; anti-fatigue Description: the same volume of material made of magnesium alloy frame durability than aluminum alloy frame bad. Magnesium alloy is also fatally flawed. With the number of cycling more, stress is also the higher the frequency of occurrence, intensity will be significantly reduced, or even frame Life expectancy does not exceed 2-3 years of professional riders so rarely used magnesium alloy frame, if the use of race, is calculated using the mileage to abandon the form of replacement.
4; elastic modulus Description: Materials made of magnesium alloy frame rigid aluminum alloy frame than the bad, the same thickness and diameter of the frame made in the actual riding will absorb more of the impact of trampling intensity riding efficiency.
5; metal oxidizing Description: on the periodic table of elements clearly show that magnesium alloy aluminum alloy more easily than the oxidation corrosion.
6; manufacturing costs Description: are lively because of magnesium alloy metal, manufacturing equipment and the environment so there is a higher demand, resulting in high manufacturing costs, production cost by far less than a bike frame and aluminum alloy frame.
Conclusion: The magnesium alloy because the proportion of the characteristics of density only in the space industry at present, military aircraft, 3C industry on the use of more.
