本文讨论了从双波纹管差压流量卡片上，用求积仪求得差压和静压的平均值计算天然气流量方法所产生的附加计算误差；分析了差压和静压在不同的变化趋势下，附加计算误差的大小和方向；提出了改进和预防的建议。

A coalition government between the NDP and Liberals, supported by the Bloc Quebecois would undermine democracy because Jack Layton, Gilles Duceppe and Michael Ignatieff would govern without the consent of the Canadian voter.

一个依靠魁人政团支持的新民主党和自由党联合政府将会破坏加拿大的民主制度，因为杜鍚、林顿和叶礼庭将会在没有加拿大选民同意的情况下获得国家的管治权。

Take the opportunity of this project, theoretical and experimental researches on the high-efficiency evaporator used in a large quick-freeze equipment have been done. The main work of experimental research is as follows:(1) Compare and analyze the influences of structural parameters on the heat transfer coefficient of an evaporator. The calculation results show that, under non-freezing conditions, the structure possessing the highest heat transfer coefficient is the one with circular fins, equilateral-triangle arranged small tubes and varying fin-spacing.

主要做了以下几方面的试验研究工作：(1)对不同翅片形状、管径大小、翅片管排列方式，以及是否带波纹等结构参数对蒸发器传热系数的影响进行了比较分析，得出在不结霜工况下，具有最高传热系数的蒸发器结构是圆翅片小管径正三角形排列等节距结构的结论。

Methods to ivestigate 22 cases esophagograms by the digital radiology, and these cases which their postoperative pathological diagnoses were early esophageal carcinoma,4 cases were epithelial carcinoma,7 cases were intramucosal carcinoma,11 cases were submucosal carcinoma.results from the characteristic finding in esophagograms of early esophageal carcinoma, we can find, the foic of esophagus are short, the abrupt change in caliber,ragged edge,mucosal fold hypertrophy or interuption, and may be have spots of barium stay in.conclusion digital radiology in esophagraphy is demonstrated to be a valuable technique, which can improve the detection rate and diagnose rate of early esophageal carcinoma.

分析近期应用数字胃肠机检查发现的经手术病理证实的22例早期食管癌的x线表现，其中上皮癌4例、黏膜癌7例、黏膜下癌11例。结果：短期内发现的早期食管癌，病变段短，局部管壁微凹僵直，部分边缘稍不整，黏膜增粗、中断或有浅在小钡斑滞留。结论：数字胃肠机在提高早期食管癌的检出率和诊断准确率中具有重要价值。

Dishonestly, the driver wanted more tips than we confirmed when he got us back. It perfected Helen in her words with the driver skilfully."drive us the police office if you want to keep the changes","Yes, we should never spoil them with money". Both Ginger and Helen spoke emotionally. The Richshaw driver gave up finally. The hot weather made us hungry with the watermelon behind. And we started to eat on street without any gentle pose. Ha! We got used to Indian living style

这个司机真不地道，讲好了价格，到了地儿却想多要，不给就不找零，这下思维的吵架技巧又得到了充分发挥，"不找零可以，但你得把我们拉到警察局再说""就是不能惯他们毛病"，司机只好乖乖的找了零钱，转了身就是买西瓜的小摊，买个西瓜吃吧，印度这几天就没怎么吃水果了，天还这么热，管什么淑女不淑女的，我们已经很印度了。

利用氦气在不同压力下具有不同的状态参数和热力参数，可以通过传热方法测量包壳内的氦气压力。1试验装置和研究方法如图1，把燃料棒浸入到一个高温的池子内，热量会在燃料棒内传递开来，通过测量管壁外面不同位置出的壁面温度，就可以推测到包壳内的氦气压力

If any droplets of water adhere to the walls of the receiving tube, scrub them down with a brush consisting of a rubber band wrapped around a copper wire and wetted with toluene.

如果任何水滴附着在接收管的壁上，将铜丝缠绕橡皮圈的刷子，用甲苯润湿，将之刷下，当水和甲苯已经完全分离，读水的体积数，并计算样品中存在的水分百分含量。

Because he closed my carriage door outside sir Thornley Stoker's one sleety day during the cold snap of February ninetythree when even the grid of the wastepipe and the ballstop in my bath cistern were frozen.

九三年二月间下雨夹雪的一天，冷得连污水管的铁格子和澡缸的浮球活栓都结了冰。在索恩利。斯托克爵士的住宅外面，他替我关上了马车门。

Short change-over times, a broad achievabie range of the yarn properties, low slub levels and small yarn breakiates are at very least just as important in today's market situation as the speed factor.

灵活性(如短的筒管转换时间、较宽的丝条特性范围、低的纱结率和低的断头率)在当今的市场形势下和纺速因素同样重要。

To simulate the actual combustion, puts a flat of sediment on the soleplate in the air duct and measures the temperature field in the air duct, by thermocouples when the fire happens in the condition of different air velocities, different air duct sizes and different distribution of the sediment.

为了模拟实际燃烧状况，在实验风管内底板上平铺一层聚积物，在不同的回风速度、不同的风管尺寸以及不同的聚集物厚度的条件下，利用热电偶测量火灾时风管内的温度场。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
