"Long end " this one concept is the earliest by " even the line " Chris Anderson of magazine editor in chief put forward in October 2004, those who grow end theory illuminate is cornucopian aid learns actually --" when us the bottleneck of supply and demand in culture begins to disappear, when all products can be obtained, long end story is met abiogenesis ".

&长尾&这一概念最早由《连线》杂志总编辑Chris Anderson于2004年10月提出，长尾理论阐释的实际上是丰饶济学——&当我们文化中的供需瓶颈开始消失，所有产品都能被人取得的时候，长尾故事便会自然发生&。

"Wire Bonder" is the most costive equipment in the investment of IC packaging; and the packaging quality, cost and delivery are concerned most in the assembly processes. An inappropriate process scheduling may result in the wastes of resources and assembly bottleneck. Manager must allocate the resourcesappropriately to adapt the changeable products and production lines.

在半导体封装制程中，以焊线制程所投入的设备及成本最大；相对的，其制程的安排亦主导著封装的品质、成本与交货速度，若排程或派工决策不良，则将导致资源的浪费，与制程瓶颈的产生，因此在有效的资源分配的前提下，管理者必须即时分配资源以应付产品快速转换的需求，进而达到最适的排程与派工规划。

Introduced the process about identifying the principle of heating system to improve decarbonization of 60Si2Mn spring flat steel ,In the measurement and analysis process of the decarbonized improvements of spring slab and finished flat steel,bottlenecks of the decarbonized reasons are found by applying statistical techniques.

介绍了60Si2Mn 弹簧扁钢脱碳改进中加热制度原则的确定过程，在弹簧方坯和成品扁钢脱碳改进的测量和分析过程中应用了统计技术，直观、定量找出了脱碳产生原因的瓶颈，提出了进一步的改进措施，探讨了统计技术在品质改进中的重要作用。

To analyze the core viewpoint of Deng Xiaoping science and technology view with the system approach, we should dialyze it inevitably from the productive forces function, the economical function and the social function dimensions. Under the background of the contemporary scientific and technological globalization,the competitive power of high technology already became the core competitive power in the world.

在当代科技全球化的时代背景下，高新技术的竞争力已经成为国际核心竞争力，我国又处在经济社会转型的关键时期，要落实&科学发展观&战略，必须贯彻邓小平科技观，依靠科技创新，特别是提高自主创新能力，走&创新型国家&道路，才能破解经济社会发展&瓶颈&，实现全面、协调、可持续发展。

All the above researches are very important to the usage of thelaser Doppler technique in seismic prospecting.The laser Doppler frequency shift of scatters and diffract grating was discusstheoretically.

鉴于地震检波器是制约高分辨地震勘探的重要瓶颈，研究应用激光多普勒效应的新型地震检波器是重要工作之一。

Asymmetric over-introgression of the indica alleles on chromosome 7 and many specific regions on other chromosomes in the japonica genetic background is consistent with the general trend observed in the RIL and F_2 populations of the same cross, suggesting a high genetic load in the japonica gene pool, and japonica genome experienced a very severe bottleneck by artificial domestication.2 Genetic background effect on QTL expression of grain weight and its related traitsGenetic background effect on main-effect QTL and digenic epistatic QTL mapping for GWT and its related traits including GL, GW and GT was dissected by a large set of reciprocal introgression lines and recombinant inbred lines derived from Lemont and Teqing in Beijing environment.

籼粳相互导入具有不对称性，粳稻向籼稻背景的平均导入频率与期望值相仿，相反籼稻向粳稻背景的平均导入频率大大高于理论预期，位于第7染色体和一些其它染色体的特殊区段存在籼稻等位基因的超导入现象，在来自相同亲本的重组自交系和F_2群体中也观察到同样的导入趋势，表明粳稻基因组具有较大的遗传负荷，粳稻品种在人工驯化过程中曾经历过一个非常剧烈的遗传瓶颈。2水稻籽粒相关性状的主效和互作QTL表达的遗传背景效应利用Lemont和特青培育的双向导入系和重组自交系群体，在北京环境下定位影响千粒重及其相关性状如粒长、粒宽和粒厚的主效和互作QTL，分别在特青背景导入系、Lemont背景导入系和重组自交系下检测到影响千粒重及其相关性状的主效QTL分别为33个、27个和13个，互作QTL分别为4个、8个和23个，其中仅有6个主效QTL(QGwt5，QGl1，QGl3b，QGl4，QGw7和QGw8)在籼粳两个不同背景下共同表达，3个主效QTL(QGwt5，QGwt7a和QGt5)在导入系和重组自交系中共同表达，分别占检测到影响这些性状QTL总数的11.1%和4.3%，未检测到在3个背景下相同表达的互作QTL。
