It is put forward that the icing stress product, defined as the product of the ice-layer conductivity and the ice layer weight per centimeter of dry arc distance can be taken as a characteristic parameter to indicate the effect of ice accretions and contaminants on the flashover voltage.

例3：本文分析了覆冰XP-70绝缘子长串的交流闪络特性，并提出覆冰水电导率r20 (换算到20 ℃时的值)与覆冰量w(每片绝缘子上的平均覆冰量)的积δ0可作为表征覆冰和污秽对绝缘子串最低闪络电压影响的特征量。

At host densities of 5, 10,25, 50, 100,or 200 aphids/day the parasite lived average of 3.6-5.8 days at 22℃.

在22℃下在寄主密度分别为5，10，25，100或200头／d蚜虫时，寄生蜂平均寿命为3.6～6.8d。

The results indicate that the Sauter mean diameter is smaller and the diameter distribution is more uniformity for the droplets obtained from a pulsating flow than those from conventional atomizers.

试验结果分析表明：脉动气流频率越大、料液流量越小和料液粘度适中时雾化效果最好；采用脉动气流雾化得到的雾滴的Sauter平均直径更细，粒度重量分布均匀，。

For a luscious break from August temperatures that average 84°F (28.9°C), a young herder does refreshing backflips off water buffalo taking their daily bath in the Turag River just west of Dhaka.

自八月以来难得凉爽的一天，这天平均气温为84华氏度（28.9摄氏度），水牛在达卡以西的杜拉格河进行每天沐浴时，一名年轻的牧人借一头水牛之背来了个清爽的后空翻。

One will discover that the average human at only 2 strands of DNA is divided into a minimum of 144 different time zones, each of which is related to personal or planetary cataclysms with records of great trauma recorded therein.

你将发现，在2股DNA时，人类平均被分割成最少144个不同的时间地带，其中每一个都与个人或星球灾难有关并带有记载在其中的巨大创伤记录。

So we ranked the past ten years' CEAs by the average quality of the economics departments where their senior economists got their PhDs.

因此我们按照高级经济师得到博士学位时所在的经济学系的平均质量对过去十年的CEA做了排名。

因此我们按照高级经济学家获得博士学位时所在的经济学系的平均质量对过去十年的CEA团队做了排名。

The results show that the precooling time of the probe is shortened significantly with the help of the vapor liquid separator, and decreases with the driven pressure. With the helical coiled wire and the helical mesh, significant thermal Oscillation corresponding the density-wave is observed in the precooling time. The average heat transfer coefficient enhances 1.5 times with the mentioned heat transfer enhancement techniques, and the temperature of the 2.5 min cryoprobe surface can reach -160℃ in 17℃ brine within 10 min.

结果表明：使用了快速预冷汽液分离器后，探针预冷时间大大缩短，并随驱动压力增大而减小；加入螺旋丝和螺旋丝网后，在预冷阶段出现明显的热力振荡，并伴有密度波振荡，平均换热系数为原来的1.5倍，在17℃生理盐水中10min时2.5min探针表面温度最低可达－160℃，大大提高了探针的冷却性能。

"Secret" Before Julian, the ex-mayor of New York took his post, almost 2000 serious criminal cases happened per day. However by 2000, New York's criminal rate dropped by half. Although it's somehow related to Mr Giuliani's work, another untold "secret" was playing a greater role.

秘密》 纽约前市长朱利安尼刚上任时，平均每天发生近2000起重大犯罪案件，而到了2000年，纽约的犯罪率降低了一半，这虽然与朱利安尼的努力有关，但实际上，却有一个更大的&秘密&在起作用。

In view of executive power to intervene in the allocation of resources over the reality of the situation, should intensify their efforts to clean up the recent各种乱收费, levies, and shut the power of the currency market of the "gray channel" reflects the strong focus on cleaning up the community, do not lead to monopolies fair competition policy, and actively create a fair and regulated competitive environment, maximizing the contribution of income and reflected on and so on; to be a more effective means of remediation of illegal income, seek to abuse the interests of individuals or small groups with severe punishment imposed for corruption ; At the same time, it is necessary to speed up the reform of the political system, and promote democratization and openness in decision-making, and strengthen the public service and acts of administrative bodies at all levels of supervision and constraints on the exercise of such power by the process of forming a comprehensive and reasonable mechanism for binding.

当中产阶级成为一个国家的主流群体时，就会结成一张维护社会长治久安的&安全网&。如果说&社会稳定是压倒一切的政治任务&的话，那么，扩大中产阶级的比重就是实现稳定的社会基础。如何促进中国中产阶级的快速发展？笔者认为当前应特别重视以下几个方面：（1）加强法律保护的力度。实践证明，只有依法保护私人产权和维护社会公正，才能促使人们凭借勤劳和智慧去创造财富，才能抑制少数人依仗权势&寻租&和通过贪污腐败手段暴富，才能防止百姓的私有财产不被权贵势力非法侵吞。这样，所有的人将可平等地获得上升的机会，私人资本和职业阶层也会有更大的成长空间。（2）大力发展公共教育事业。知识能够帮助人们改变命运，只有大力发展公共教育，才能使更多的人得到平等分享经济增长成果的机会，这是知识经济时代培育中产阶级的&树人工程&。我们要尽快普及12年制义务教育，大力开展终身教育，打造更多的学习型组织，营造学习型社会的氛围，从而使更多的人通过攀登知识阶梯而升入中产阶级。（3）加快金融创新。中国居民目前工资收入在家庭收入中的比重平均为70％左右，大大高于发达国家50％的水平。工资收入在家庭收入中的占比过大，自然会减缓大多数人进入中产阶级行列的步伐。我们认为，要提高居民收入中非工资收入的比重，最重要的措施就要培育居民的投资意识，并通过金融创新为他们提供多样化的投资工具（如形式多样的共同基金等）。（4）提高专业技术人员、经营管理者、教师、研究人员、公务员等智力劳动者的收入，鼓励智力劳动者进行智力投资，并保护相应的合法权益。（5）建立职业经理人激励机制（包括年薪、奖金、红股、期权等方式），形成职业经理人致富与企业发展互动的财富积累机制。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
