In 10.2.0.4 database alert log the following error appears: ORA-00494: enqueue held for too long (more than 900 seconds) This error can also be accompanied by ORA-600 [2103] which is basically the same problem - a process was unable to obtain the CF enqueue within the specified timeout (default 900 seconds).

ORA-00494或许还会伴随 ORA-600 [2103]错误的出现，这是Oracle10.2.0.4中引入的一个行为改变。在Oracle10.2.0.4中，如果一个进程在指定的时间（默认900秒）内无法获得CF锁，则CF锁的执行进程会被kill。从Metalink上可以发现，CF enqueue相关的bug是相当的多，10.2.0.4这个行为的引入，估计是Oracle视图对这个问题做出解决的一种尝试。

In this paper, the FIR low-pass digital filtering method is first introduced for reducing the effects of noise signals in the experiment of velocity measurement of high-temperature flue gas flowing in pipe. The experimental results indicated that, only one peak presents in the cross-correlation graph, which is in good agreement with theoretical analysis result. Secondly, the temperature and pressure pulse signals of the high-temperature flue gas, obtained by thermocouple and pressure sensor, are introduced to explain the applicability of sensor characteristics.

本文介绍在测量管内流动的高温烟气流速的实验中采用FIR低通数字滤波器滤波方法可以排除干扰信号的影响的研究，实验结果证明，经过滤波处理后的信号互相关函数的图形不会出现大小相当的多个峰值，符合理论分析的结果；其次，本文还介绍了用热电偶和压力传感器采集的烟气温度和压力脉动信号，分析了传感器特性对相关测速的适应性。

On the other hand, when we are proving the upper bounds of the Hausdorff measure functions for the level sets, although we get the answer to the cases for the symmetric processes, we had to consider multi-integral of highly dimensional functions, the proof is quite complex. Therefore, we suggest that the proof for the corresponding problem needs some new ways.

另一方面，我们在证明严格稳定过程的水平集的Hausdorff测度函数的上界时，虽然我们得到了对称的多参数稳定过程的水平集的Hausdorff测度函数上界，但是我们的方法必须考虑多重的高维积分，其证明过程也已经相当复杂，因此，我们认为，为了得到一般的严格稳定过程的水平集的Hausdorff测度函数上界，还需要引入其它新的研究方法。

Results: The major findings are:(1) the public held strong belief in the preventability of AIDS/STDs and considered prevention was of greater importance than biomedical interventions,(2) of the possible prevention strategies proposed by the research participants, personal behavior control was deemed as the most ef fective; meanwhile a sense of powerlessness was expressed while mentioning the government's responsibility for keeping the quality of blood supply and managing the potential dangers posed by other people's behavior,(3) condoms were well accepted as an effective tool for AIDS/STDs prevention but were used mostly for the purposes of contraception than HIV/STDs prevention, and (4) people were unwilling to use condom mainly due to sensational and psychological discomforts.

结果：(1)民众多认为爱滋病的「可预防性」极高，且视预防比高科技的解决方式重要；(2)个人行为的控制乃最受民众重视的防治途径；但对政府的血液安全管制及他人行为所可能造成的危害较感无力；(3)民众对保险套之使用持相当肯定之态度，不过曾使用者绝大多数以避孕而非以预防性病为主要目的，男女性在这方面的行为差异极大；(4)身体及心理上的不适与不悦被一般民众指出是保险套使用率低的主要原因，(5)教育程度对民众在预防的认知及信念扮演极重要的角色。

The second is the variation of security mechanism.

冷战后时代，随着军事威胁的相对减轻和非军事性挑战的出现，国家安全观开始发生变化：一是安全内涵的综合化，国家安全已不局限于军事领域，相当程度上是军事领域之外的问题；二是安全机制多样化，随着冷战结束以及国际形势的发展，合作安全这一新的安全机制日益发展起来；三是安全威胁复杂化，各国或地区面临的直接外部威胁下降，对国家安全构成威胁的因素是多方位、多层次的。

But the countries have different opinions on economic、soc ial and cultural rights,which are important to the minority.After comparing and analyzing the cultural tradition of some countries on right issues and the varia nt theories of equality,the article points out that on such issues as the econom ic social and cultural rights,positive actions should be taken and diverse discr imination should be avoided to give the minorities more opportunities to partici pate in social competition and realize complete equality in the whole society an d more equality with more justice.

然而，在对少数人具有重要意义的经济、社会、文化权利上，各国却有不同的看法，本文在比较了各国在权利问题上的文化传统和近现代的各种平等理论之后，分析指出在以经济、社会、文化权利为核心的相当一部份权利上，各国政府应当在避免形成"反向歧视"的前提下，采取积极措施，让少数人有更多机会参与社会竞争，实现社会整体的平等和更公正意义上的平等。

In our media businesses, such as the Buffalo News, we sell advertising. In other businesses, such as See's, we are buyers. When we buy, we practice exactly what we preach when we sell. At See's, we more than tripled our expenditures on newspaper advertising last year, to the highest percentage of sales that I can remember. The payoff was terrific, and we thank both Hal Riney and the power of well-directed newspaper advertising for this result. See's splendid performances have become routine.

在我们的媒体事业，像是水牛城报纸，我们贩售广告，在其它的事业，像是喜斯糖果，我们是广告客户，反而变成买主，然而当我们买广告时，我们做事的方式跟我们当初在卖广告的诉求是一致的，去年喜斯糖果在报纸广告上的花费增加了有三倍之多，是我印象之中占营业额的最高比例，不过所得到的回报却更是惊人，对于能有这样的成绩，我们相当感谢 Hal Riney 与报纸的宣传效果。

You certainly did your share in this respect last year. The 194300 square foot hall adjoining the meeting area was filled with the products of Berkshire subsidiaries, and the 21000 people who came to the meeting allowed every location to rack up sales records. Kelly Broz ( neé Muchemore), the Flo Ziegfeld of Berkshire, orchestrates both this magnificent shopping extravaganza and the meeting itself. The exhibitors love her, and so do I. Kelly got married in October, and I gave her away. She asked me how I wanted to be listed in the wedding program. I replied "envious of the groom," and that's the way it went to press.

去年各位的表现相当不错，面积19.4万多平方英呎的会场中布满了Berkshire关系企业各式各样的产品，21000名出席的股东让股东年会期间产品的销售数量屡创新高，Kelly Broz - Berkshire的齐格飞，主导了整个股东年会的购物秀，所有参展的公司都爱死她了，当然我也一样，Kelly去年十月结婚，我被迫放弃掉她，她问我在婚礼上该如何被称呼，我回答说「最嫉妒新郎的人」，结果喜帖上还真的就这样印。

By flue gas of 2000m〓/h, some normal wastes (seawater, fly ash of power plant, basic waste water, etc) and lime are used on the research of dry, semi-dry, and wet FGD and its corresponding pressure and temperature decrease on stuffing tower, the effect of Ca/S ratio, inlet SO2 concentration, inlet flue gas temperature, and L/G ratio on desulfuration efficiency is analyzed, the instrument of dehumidify was studied by experiment and appropriate instrument of dehumidify was chosen.
