Because the light power in claddings is weaker than one in core, the overlap will weaken when modulation is realized only in cladding.

由于包层中光波强度比芯层中要弱，因此在包层中调制光波会引起场模交叠因子的弱化，但是优化计算发现，通过调节波导的尺寸尤其是芯层厚度可以控制交叠因子使其弱化程度降低到最小，在最优的情况下，场－模交叠因子可达0.89。

From the statistical data analysis, real estate in the first quarter of this year's investment growth rate as high as 41.1 percent, slightly lower than the 43% investment in fixed assets increases, while the experience of about half a year of control, solid cast in the August an increase of 26.2 percent, while real estate investment during the first 8 months the average is still 28.8%, indicating the need to increase the real estate industry is still quite the consolidation efforts, otherwise they will be a waste of limited land resources, and in many aspects negative effects:(1) urban land supply is relatively limited, and particularly in coastal cities for the likelihood, the land and property prices in speculations will be driven by continuing higher, so that industrial and commercial service industries and residential property prices and rental values of retail trend or, an increase investor, home-owners or hirers of the burden of adverse business, and they may even like Hong Kong after a number of years due to land and property prices and rents are too expensive to make industrial and commercial operation of the service industry high cost, and even so that the quality of life for the people affected by high land prices and property prices have a lower erosion.

从统计数据分析，房地产在今年第一季度的投资增长速度高达百分之41.1 ，稍低于43 ％，固定资产投资增加，而经验约半年的控制，固投在8月增加了26.2点，房地产投资在头8个月的平均水平仍然是28.8 ％，表明有必要增加房地产业仍然相当巩固的努力，否则将会浪费有限的土地资源，而且在许多方面的负面影响：（ 1 ）城市土地供应相对有限，特别是在沿海城市的可能性，土地和房地产价格在投机的推动下将继续走高，因此，工业和商业服务行业及住宅物业价格和租金价值的零售趋势，或增加投资，以家庭为业主或租户的负担，不利的业务，他们甚至可能会像香港一样若干年后，由于土地和物业价格及租金过于昂贵，使工业和商业运作的服务行业成本高，甚至，这样的生活质量受影响的人高地价楼价较低侵蚀。

The controls allow the operator to access feedback on each part in a run, troubleshoot any problems and adjust tonnages and speed as necessary, identify the most efficient way to produce a part and reduce cycle times.

在触摸屏控制帮助下，操作人员可以获得设备各个部分在运作过程中反馈的信息，从而对出现的问题进行排解，必要时对吨位和速度加以调整，寻找生产部件的最有效方法，缩短工作周期。

The narrative subject is the urban individual repetition of the grand narrating under the control of the new ideology, which has the function to de-construct and overthrow the legality of the latter. The narrative object of the Dushi Minjian pays attention to the powerless public whom were concealed by the false promises of the mainstream social modernization, thereby the original Tightness and the humanism thought could be found. The narrative form is not a kind of pure narrating of Minjian area, but concentrated on the aesthetic space, thus self-speech would harvest its possibility, significance and value consequentially in the multifold narrating among the political discourse, commercial discourse and the intellective discourse.

它具体表现为：在叙事主题上，都市民间的个人叙事是对新意识形态控制下的宏大叙事的重述，并在个人的重述中实现对后者合法性的瓦解和颠覆；在叙事对象上，都市民间叙事关注的是被主流社会现代化虚伪承诺所遮蔽的弱势的人群，从而表现出知识分子的原始正义和人道主义关怀：在叙事形态上，没有纯然的民间叙事，对民间审美世界的关注，必将使其在政治话语、商业话语和知识分子话语等多重叙事中获得了自我言说的可能、意义与价值。

In order to control labor effectively, British settlers inclined to adopt the extraeconomic compulsory means as well as economic ones under the influence of the racial labor relation of which boers were fond.
