  estimated price
For Canadian exports to the United States, we find that the simultaneous and joint estimation procedures bear heavily on the estimated price elasticities.
      
The results show that the estimated price-cost margin is in the range 0.59-0.67, which is close to the estimates obtained in the United States market.
      
The price impact of tariffs was based on the ad valorem tariff rate while the price impact of quotas was based on estimated price differences between domestic and imported apparel at the same U.S.
      
The results regarding estimated price intuition and use of intuition in estimating prices are also consistent with a slow adaptation process.
      
An estimated price elasticity of -0.77 and income elasticity of 0.56 suggest a high level of responsiveness to economic incentives among heavy drug users.

In this paper, several kinds of devices for tracking the sun and concentrating the sunlight are reviewed, their working principles are described based on the theory of astronomital instrument, then their merits and demerits are compared. The author has made some calculations for three devices and found that among them the best one is the altitude - azimuth telescope which needs only one large mirror with minimum size.

In this paper, several kinds of devices for tracking the sun and concentrating the sunlight are reviewed, their working principles are described based on the theory of astronomital instrument, then their merits and demerits are compared. The author has made some calculations for three devices and found that among them the best one is the altitude - azimuth telescope which needs only one large mirror with minimum size. The heliostat, which is widely used for solar observation and solar energy plart[1], does not seem suitable for our purpose,as it has to use at least two mirrors with larger size.

为了将阳光引入建筑物室内,必须建立一套能够自动跟踪太阳的机械装置,将作周旋转运动的阳光引到固定方向,并将由大口径反射镜定向的光束的直径缩小,以便通过小直径的导光管引入建筑物内部。 广泛应用于太阳能电站的定日镜结构简单,但由于太阳光对镜面是倾斜入射的,再由于太阳光束的自身旋转,反射镜不能得到充分利用,以致跟踪装置结构庞大,经济上不合理。比较好的解决途径是采用大口径天文望远镜的所谓地平式结构,它的主返射镜始终对准太阳,因而避免了有效反射截而的损失,比定日镜的结构尺寸小得多。对于建筑物采光,对太阳跟踪不需很高的精度,不存在工程技术上的难题,可以用较低的价格实现。 文章对照明面积1000米2,室内最低照度为200勒克司的情况进行了计算,对极向定日镜,水平定日镜和地平式望远镜三种结构进行了比较,结果如表1所示,此外,提出了三种结构的估计价格。 表2给出合用地平式望远镜的结构,一年内可达到的室内最高照度(对于北京,地理纬度40℃) 地平式望远镜装置的基本公式为: cosE=sinF+CosF SinD CosT tgA=CosDsinT/-SinDCosF+CosDSinfCosF式中:F——建筑物所在地的地...

In China there is less elasticity in the demand for agricultural products and their yields,butthere is a relatively greater elasticity in commodity rates.The speciality of moving rules of the price of agricul-tural products has formed a discounted effect of commodity rate on the increasing price of agricultural prod-ucts.The degree of increasing of farmer's income with improving price is much less than what we have pre-dicted.And if the rise in price of agricultural production means were not effectively controlled,improvingagricultural product price would lead to reducing farmers'income.So,the effect of price change on agricul-tural production,especially on food production,must be correctly valued.Enough supports to farmers'self-supporting production must be kept to increase the amount of agricultural commodity.

我国农产品需求缺乏弹性。生产量弹性小,商品率弹性相对较大.农产品价格运动规律的特殊性形成了商品率对农产品提价效应的折扣作用.提价给农民带来的增收效应要比预想的小得多,如果生产资料伴随涨价不能得到有效控制,则农产品提价经常会产生农民减收的逆向效应.因此必须正确估计价格杠杆对农业生产尤其是粮食生产的调控作用.当前稳定和发展农业的现实措施应该是:对农民的自给性生产予以足够的重视和支持,并以此带动商品性生产的发展.

Before 1998, nickel supply exceeds demand in international market, but since then nickel has been in short supply for four years. It's estimated that nickel supply and demand are going up steadily. Its price, up and down alternately, has gone up in 2002 and will keep a constant rising.
