The revenue of international roaming business is not as high as other sectors of telecommunications business; however, we found that the international roaming business meets the curve of Long Tail. After analyzing the three forces of forming a long-tail market, we discovered that international roaming itself is a virtual e-commerce to provide pure digital products for users and its marginal cost of inventory and marketing is nearly zero. In addition, the outbound or inbound roamers can easily use the roaming services through recommendation and searching machines under the structure of international interconnection and bilateral agreements.

国际漫游业务因性质上的缘故，在整体电信服务营收占比并不高，本非属热门商品之范畴，但透过「长尾理论」中形成长尾市场三股力量的分析，发现行动通信业务本身具有虚拟电子商务型态，得以提供纯粹数位商品，使得库存和配销的边际成本趋近於零，应证了「配销工具大众化」的条件；另藉由国际电信间的网路互连以及漫游商业协议下，使得出境或入境漫游者皆得透过推荐与搜寻方式使用原有之电信服务，亦应证「连结供给和需求」条件的存在。

The ZOOMLION KSD25 Dry-Wet Horizontally directional Drill is the first drill which drills through hard rock without a bentonite and mud pump. Its pneumatic percussive technology has not only solved the problem of mud pollution, but also has increased its efficiency 40% higher than a normal drill. Additionally, its cost is also much lower, and therefore, it has been considered as a most efficient solution for complicated stratum (including pebble and gravel, backfill and rock).

中联KSD25干湿两用水平定向钻孔机是我国第一台不使用膨润土和泥浆马达就能在硬岩中钻进并导向的钻机，其国际领先的气动冲击钻机技术不但不存在泥浆污染的问题，而且效率比普通钻机提高40％以上，成本也要低廉得多，被公认为目前对付复杂地层（包括卵砾石、回填土和岩石地层）最为有效的方法。2 s# C J， k5 _% C

The invention has the advantages that: 1 the preparation method is simple, the obtained pine needle essential oil has good quality and higher yield, the yield is increased by 30 to 49 percent or so compared with that of directly adopting the steam distillation; 2 the hydrophilic ionic liquid can be reclaimed and recycled by adopting the ion exchange method, which can not cause the environmental pollution.

本发明的优点：1制备方法简单，得到松针精油质量好，得率较高，比直接采用水蒸气蒸馏法的产率高30～49％左右；2亲水的离子液体可以采用离子交换法回收循环使用，不会造成环境污染。

Key characteristics of 911 building demolition events: Straight Down Motion - Sudden Structural Failure - Buildings Collapsing At Free-Fall Speed - Total Collapse Of The Entire Load Bearing Cores - Many Examples of Cleanly Sliced Heavy Girder Steel Core Supports - Dust Clouds Containing Heavy Girders In Highly Energetic Horizontal Motion - Horizontal Ejections Of Heavy Girders And Pulverised Concrete Onto The Tops And Embedded Into Surrounding Buildings - Rescuers Reported And Seismic And Other Detectors Recorded Energy Dissipation Produced By Many Explosions (Recorded in real time by several different independent sources) In addition: Pools of molten Steel recorded over 1 week after collapse in the sub-basements (Refer to paper written by Physics Professor Steven Jones) Closer inspection of original video evidence shows heavy steel core columns turning to dust within seconds – question:- was a novel "StarWars type" energy directed beam weapon used in conjunction with explosives to undermine the integrity of the twin tower complex?

关键特征911房屋拆迁事件：直上下动作-突然结构上的故障-建筑物倒塌，在自由降落速度-彻底瓦解整个承载内核-很多例子，干净利落地切成沉重的大梁钢为核心的支援-尘土含重，在大梁高能水平运动-横向抛射重的大梁和青山混凝土上，车顶嵌入到周围建筑物-救难人员据报，地震和其他探测器记录耗能所产生的许多爆炸事件（记录在实时性，由几个不同的独立消息来源），此外：池钢水录得超过一周后崩溃，在分库（指书面文件，由物理教授史蒂文琼斯）加强检查，原来录像证据表明，重钢芯柱谈到粉尘数秒内-问题：-是一种新型的&为Starwars型&能源定向粒子束武器配合使用炸药完整性的前提下，在双塔复杂吗？

It is extremely convenient to use this SL253 presser. A sample piece can be pressed with just one pull of the handle, which is much more convenient than pressing with other pressers which need several or scores of actions of the hands. It is almost as convenient as an automatic sample presser, and is more economical than it because a automatic sample presser is more expensive and is easy to have motor failure.

SL253型压片机使用极其方便，只要用手扳一下，即可完成压样，相比其他手动压片机需压几下甚至几十下要方便得多，相比自动压片机也差不多，但自动压片机电机等容易出现故障且价格较高，所以在性价比上更胜过自动压片机。

Currently in a surface warship of the our country everyplace all provided with the sail coal gas body to report to the police the instrument on the boat, gas density that sensor adopt to convey gas density value traditional 4-20mA mode of analog signal, have to each measure passway allocate one is it is it report to the police to measure to have and density value show measuring board of function, as the density of gas measures the passway board of the different quantities of different outfit of the figure of the passway, but there is many figure of the large-scale naval vessel passway, so the volume of warning system will become very huge , unfavorable to attenbants to use, and traditional 4-20mA electric current ring transmits the signal, unfavorable to transmitting at a long distance, easy to bring and interfere.

核心提示：摘要目前在我国各地型水面舰船上都配备了航煤气体报警仪，气体浓度传感器采用的是传统的4-20mA模拟信号的模式传送气体浓度值，只好每个检测通道配备一块具有检测报警及浓度值显示功能的检测板，随着气体浓度检测通道数目的不同配备不同数量的通道板，但大型舰船通道的数目比较多，因此报警系统体积会变得十分庞大，不利于操作人员使用，而且传统的4-20mA电流环传输信号，不利于长距离传输，容易带来干扰。为了巡检的需要，需要将其改造成现场智能仪表，通过将传感器检测结果

Each stage gets progressively more difficult, and you may only use your Pixies so many times before powering them back up by eliminating the special blocks that randomly appear in each board.
