某日上午10：30左右，监控中心收到报警，发现F座10楼厨房附近窗户有浓烟冒出。监控中心立即通知安防员携带消防工具赶到现场，并及时关闭了F座10楼的电源总开关及燃气总阀，来到单元门口时正遇业主返回，便协助业主迅速打开房门，此时屋内烟雾较大，厨房基本已经被浓烟覆盖。安防员迅速打开各窗户，在做好自我防护措施后进行灭火操作。事后确定是微波炉短路引发火灾。由于发现及时，当值安防员在监控中心指挥下，快速赶到事发地将火扑灭。此次火灾烧毁了部分橱柜及一些餐具等，部分天花板被熏黑。由于扑救及时，未对业主财产造成更大损失。

22.一些事件，在物业管理服务活动过程中突然发生，而且需要立即处理，试分析这些紧急事件具有哪些性质？ 23.对处理紧急事件的要求有哪些？ 24.紧急事件处理事后阶段考虑的内容有什么？ 25.本案例中，没有造成重大事故的主要原因是什么？

The definition of the standard kilogram is almost entirely wrong. Getting that definition right is a challenge that has tried the patience and intelligence of scientists for decades.

Scientists use just seven basic units to define all the other quantities we use — quantities such as speed or electric power. All of those basic units except the kilogram are themselves defined according to natural properties（属性）that are beyond human control.

For example, the standard second (time) is defined as a specific number of vibration（振动）of a type of radiation sent out by atoms of a special metal. The standard metre (length), in turn, is defined as the length of the path light travels under certain conditions.

Not so the kilogram. This orphan of the basic unit family is simply the mass of a small platinum-iridium alloy cylinder（铂—铱合金筒）locked away in a container maintained by the International Bureau of Weights & Measures in Sevres, France, near Paris. Official bodies around the world have copies of the cylinder.

Embarrassingly, the last time the copies were brought to Sevres for a checkup in the 1980s, officials found that some copies had gained about 20 parts per billion in weight compared to the master cylinder since the previous checkup in the 1940s. This implies that the master cylinder itself may be an inconstant standard.

Several efforts in several different countries are under way to redefine the kilogram according to basic physical quantities such as counting the actual number of atoms of a specific substance in a kilogram or the electromagnetic（电磁的）force that balances a kilogram mass against gravity. A project of the latter type at the laboratories in Gaithersburg, Md., hopes eventually to define mass by means of electrical units.

So far, none of these redefinition projects has borne fruit. They require the very accuracy of measurement and control of experimental conditions. The slightest influence — even a tiny change in weather — can ruin results. You’ve got to hand it to scientists who are willing to devote many years to such painstaking — but extremely important — research.
