Hence, the traditional factors play a determinative role to the formation and development of oil-gas industrial cluster; however, they have shortages at the same time, such as the uncertainty of natural resources, transportation cost influenced by market, irrational external division, and transaction fee.

同时，传统因素在油气产业集群发展中存在不足，如自然资源优势中存在诸多的不确定因素、交通成本受市场函数影响、分工专业化中的外部分工不尽合理、交易费用理论的局限性等。

Currently, the development circumstance of Chinese corporate ethics cultural is not optimism, existing many problems, such as resource extravagancy, environment pollution, trustworthiness imperfecti...

目前，中国企业伦理文化发展情况不容乐观，存在许多问题，如资源浪费、环境污染、诚信缺失、贪污受贿、无视利益相关者的存在等等。

At the same time, some deep-rooted contradictions and problems still exist in Shaanxi ' s economic and social development, namely, the uneven development between the urban and rural areas, the lag of urbanization process, the weak county-level economy, slow development of the non-public economic sectors, the arduous task of energy saving and emission reduction, low level of market-oriented and open economy, low income level of urban residents, concept and system obstacles. Problems including bureaucratism, formalism, extravagancy and wasting are also in existence at various level in some areas and government departments.

与此同时，我省经济社会发展中依然存在一些深层次矛盾和问题，主要是城乡和区域发展不够平衡，城镇化进程滞后，县域经济实力不强，非公有制经济发展不快，节能减排任务艰巨，市场化和对外开放水平不高，城乡居民收入偏低，观念和体制的束缚尚未消除，一些地区和部门还不同程度存在官僚主义、形式主义和奢侈浪费等问题。

Know to all, The refract wave exist an precondition, that is the bottom medium velocity is bigger than upper, then medium interface produce the refractive wave, if the medium exist the speed turn in reverse, and low speed in false bottom, the medium interface can not calculate.

众所周知，折射波存在的前提是下层介质的速度一定要大于上层介质的速度，这样才能在界面形成折射波，如果存在低速夹层和速度倒转，则利用折射波来求取表层结构难以进行。

But there are some disadvantages in this system, especially it is difficult to select the exact line with fault.

但是该系统目前还存在不足，尤其是故障选线保护存在相当大的难度。

First of all, this paper introduces the whole design project and interrelated knowledge about Non-destructive detection, ultrasonic detection, and Phased-Array ultrasonic detection Then the paper depicts the principle of Phased-Array focus and abstracts a set of math model and feasible arithmetic on the base of the real parameter of the system. Put forward several problems that exist during the course of system development and program. Introduce some measures of distinguish that are often used in non-destructive detecting and echo wave crest. Then I depict one of the measures in detail that used in the course of non-destructive detection, which is the way of distinguishing whether defects exist or not. Then provide part core program to realize it. This paper also provides main flow chart through analyzing how main control program controls different parts to make the whole system more effective.

然后在文中以较大的篇幅，描述了相控阵聚焦的原理，并根据该系统的实际参数，抽象出一套数学模型和可行的算法，在此基础上提出了在系统开发过程及编程实现过程中存在的一些问题；介绍了在无损检测中缺陷的分类和对回波峰常用的识别方法，详述了系统开发过程中使用的其中一种识别方法，即判别是否存在缺陷的算法，并给出实现之的部分核心程序；详述主控程序如何控制各部分并协调各相关软件的工作，使整个系统发挥最高效能，并给出主要设计框图和程序。

I want to be a felling, or exist or not exist.

我想成为一个伐木者，或存在或不存在的。

So both of these fetters (6 and 7) refer to craving for types of heavenly existence.

无色界只有心存在的地方，所以和两项都是关於贪求天界的存在欲）。

Based on the analysis of multiphase flow in vortex field,including the analysis of forces exerted on and the movement of droplets,the mechanism of vortex field coalescence was investigated.

在对旋流场内多相流的分析，包括分散液滴的受力和运动分析的基础上，研究了旋流聚结的机理，并通过试验验证了旋流场内聚结过程的存在，且发现在某一进料流量时聚结效果特别明显，即存在最佳进料流量或入口雷诺数。

Af ter applying this result to the conservative gas dy2 namic systems ,the semi2discrete finite difference approximation and the discrete ent ropy couple [Ut , F0j + G1j ] is searched.

关于双曲型守恒方程组ut + f x = 0 ，若存在标量熵对满足熵不等式Ut + Fx ≤0 ，则原方程存在弱解。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
