Ickery,a simplified formula on maximum across-wind response of tapered high-rise structures with circular section is achieved in this paper.

ickery提出的方法目前在国外一直应用得较为广泛[1]，但这种方法的计算过程较为复杂，不便于工程上的使用。

ZL03 2 354312.The innovations include: automatic self-closing and reliably sealed valve structure: the design of duplex valve clack with pilot valve to tackle the problem of reverse seal structured valve being difficult to be opened; an automatic drain control device to automatically drain the remaining water from the hydrant; protective plate provided between the hydrant body and the valve block to serve as a connection between the hydrant body and the valve block, which is the first one to be damaged when the ground hydrant is clashed, and prevent pulling-off of the whole above-ground part of the fire hydrant, so as to properly protect the main parts from any damage. The self-closing and reliably sealed valve now prevents drain of water, and only the damaged protective plate is needed to be replaced before immediate re-operation. Thus the repair work after clashing is very easy and simple.

其创新点为：具有能自动关闭并可靠密封的阀门结构：采用有先导阀复式结构阀瓣设计，解决反向密封结构阀门开启沉重费力的难题；设计自控排水装置，能自动排除栓体内余水；在栓体和阀体之间设计撞裂板，它既起到连接栓体和阀体的中介作用，又可在地上消火栓被撞击时率先破裂毁坏，并使露出地面的栓体不见整体脱落，有效保护各主体部件的完好无损，而此时阀门的自闭式结构可靠密封阀门阻止水源外泄，修复时只需更换损坏的撞裂板即可立即复位投入使用，使被撞后的修复工作变得十分轻松简便。

When you use these imaginary rules on yourself, you clog your mind with petty restrictions and childish orders.

因为当你使用这些发明的规则时，你会变得受约束和有孩子气的命令口气。

Early attempts to do this have been clunky, but the technology will get cheaper and simpler within a few years.

虽然早期的这种尝试失败了，但在几年内，这种科技的使用就会变得越来越简单和廉价。

The article mostly discusses gas application burning excess air coefficient calculation methods, introduces different calculation formula application range, and giving examples in natural gas, liquefied petroleum gas and manufactured gas calculate its excess air coefficient on the same oxygen content of fuel gas, and the influences of excess air coefficient to air consumption and fuel gas production during burning process.

文章主要论述了燃气具燃烧过剩空气系数的计算方法，介绍了不同过剩空气系数计算公式的使用范围，并举例天然气、液化石油气和人工煤气三气种燃气具在测得烟气中相同氧含量时过剩空气系数的计算方法，以及过剩空气系数对燃气具在燃烧过程中消耗空气量和同时产生烟气量的影响。

With the abroad use of distributed system, how to design and implement the communication protocol software is more and more important.

随着分布式系统的广泛使用，如何设计和实现通信协议软件也变得越来越重要。

Of final · of final ·· is use feeling of course, what I had used a mobile phone, have Nokia, all alone love, HTC, still have now the operation of a few new fund mobile phones, for instance LG still has SamSung to wait a moment of · of · of · of mobile phone of a lot of mountain fastness actually, for the " of " user experience that uses our IT personnel, the individual feels comparable without function of a hand to the operation of Iphone feels.

最后的最后····当然是使用感觉了，我所用过手机，有nokia，索爱，HTC，还有现在一些新款手机的操作，比如LG还有三星等等(其实还用过很多山寨手机···)，就用我们IT人员的"用户体验"来说，个人觉得没有一款手机能比得上iphone的操作感觉。

Example 8-2 shows how a script can become more complicated by using a conditional statement.
