- 一般的视频编辑软件都可以。如会声会影、ED、PR等。注意:如果将4:3屏幕宽高比的视频转为16: 9,四周有黑边。如果将16:9屏幕宽高比的视频转为4:3,则上下有黑边。另外,目前的DVD格式,16 :9的分辨率为720X576,实际上还是4:3 的宽高比,只是遮幅为16:9 宽高比。要转为真正的16:9宽高比,在设置上要选择MPEG-2格式,分辨率选择1280X720、1440X810、1920X1080,才是真正的16 :9宽高比。供参考。

- 液晶屏幕(4比3和16比9)
- 我想问一下,4比3屏真的比16比9屏逊色很多么?按照道理来说,4比3可以理解成,16比12,那不是应该包含了16比这个比例在里面吗?(只不过分辨率肯定去不到16比9的大)但是一般的1024*7... 我想问一下,4比3屏真的比16比9屏逊色很多么?按照道理来说,4比3可以理解成,16比12,那不是应该包含了16比这个比例在里面吗?(只不过分辨率肯定去不到16比9的大)但是一般的1024*768分辨率也是能观看HD高清的啊`~只不是仅仅是显示小了点?黑边多了点而已?? 展开

The exhaust air from the kitchen shall be cleaned as sufficient as possible over the place of generation by an aerosol separator accommodated in the hood. The aerosol separators shall be easily accessible, easy-to-demount and cleanable in a dish washer. To this end they shall be made of chromium nickel steel only. The rate of flow recommended by the manufacturer for the separator shall be kept. Knit fabric filters and plug-on grille filters as the only aerosol separators shall not be used. The exhaustion hoods in the kitchens which are arranged on top of kitchen equipment and used to collect vapor and steams quickly shall be designed such that a sufficiently high retaining capacity is achieved. Kitchen exhaust air hoods shall at least 0.2 m protrude over the circumference on top of the kitchen appliance. If the lower edge of the hood is higher than 2.10 m on top of the floor, a higher protrusion shall be provided (angle of opening = 12° from the edge of working areas). Collection chutes shall be free from burr and arranged such at all sides that they can be drained via drains. Hoods of chromium nickel steel with integrated lighting only shall be used as exhaustion hoods. If outdoor air lines to kitchens or other rooms are passed through fire sections, they shall be equipped with suitable and approved fire protection flaps or the pipeline shall be provided with a fire protection lining from the outlet of the room. The fire protection flaps used shall be tested and approved for the relevant case of application. Exhaust air channels shall be made of fire-resistant material. Specific measures are required for the use of gas heated large-size kitchen equipment in order to ensure the necessary supply of combustion air on the one hand and to ensure reliable exhaust gas dissipation on the other. If kitchen exhaust air and exhaust gases of gas appliances are fed off commonly, an additional safeguard shall be provided. This safeguard shall switch off the gas fired equipment if the exhaust air system fails. The high exhaust gas temperatures shall be taken into account when selecting the hood structure. In any case, gas equipment shall be operated only if the room air system is in operation. 展开
