高速高精度IC芯片粘片机是IC芯片封装的主要设备之一，其粘片速度已超过10 000次/h，定位精度达微米级，而且粘片速度和定位精度有越来越高的趋势[1]，但目前国内外IC芯片粘片机的焊头机构都采用串联结构的形式，运动部件的惯量很大，不利于粘片速度和定位精度的提高。

As on the west the company of an operation of ancestral temple will do, also be a low ebb period, also be the business of a main stream that seeks oneself, it is under this kind of big environment, got a few limitation, these restrict the company besides us besides, it is in respect of national policy limitation, a few styles with original ancestral temple are mixed on the west fixed position, we do not make an arrangement, the fixed position 10 years ago, its forum character will do, now more if locating is this locality, the netizen is participated in, we center our circumjacent crowd and life incident expression comes out so one kind is formed, this is a very big change, coinstantaneous word, we are in 3 years when, ancestral temple undertakes a few commercialized exploration on the west, commercialized exploration, also be to appear on the market a few demand of the company, if such seeing, to the development of ancestral temple had a negative development on the west.

作为西祠的一个运营的公司来做的，也是一个低潮期，也是寻找自己的一个主流的业务，在这种大的环境之下，受到了一些限制，这些限制除了我们的公司之外，在国家政策限制方面之内，西祠原有的一些风格和定位，我们不做一个安排，十年前的定位，它的论坛性质来做的，现在更加定位的是本地的话，网友参与，我们把自己周边的人群和生活事件集中表现出来这么一种形成，这是很大的一个变化，同时的话，我们在03年的时候，西祠进行一些商业化的探索，商业化的探索，也是上市公司的一些需求，这样的看的话，给西祠的发展起到了一个负面的发展。

In the field of spaceborne remote sensing, a geometric collinearity equation of pushbroom sensor with the Kepler parameters of the satellite orbit and the attitudes of sensor has been developed. Testing the sensor model on a SPOT-5 imagery, the planimetric accuracy of object positioning is 83.392m on the ground. According to the orbital dynamical model and the kinematics model of satellite attitude, an algorithm of extrapolative location is developed. Testing the algorithm on CBERS-2 high resolution satellite imageries of central China, when the depth of extrapolation is 300km, the planimetric precision is 53.555m including the measurement errors as well as the modeling error over than the 568m which is the planimetric precision of systematic rectification.

Our research and development this new product already 1 year, also not be now so short-term inside made decision, although we see very much now consumption kind the enterprise begins to locate toward low end, in order to cater to at present not quite the market environment of boom, but what we look is long-term, we feel prospective macroeconomic impetus still rises, make the appearance of hotel new job of a tallish fixed position so, long-term will look have perspective very much, but we return won't many dilate at present ' He Yi '.

我们研发这个新产品已经1年了，所以也不是现在短期内作的决定，虽然我们看到现在很多消费类企业开始往低端定位走，以迎合目前不太景气的市场环境，但我们看的是长远，我们觉得未来整体经济势头还是上升的，所以做一个稍高定位的酒店新业态，长远来看是很有前景的，但我们目前还不会大量扩张'和颐'。

The advanced and practicability of Global Position System, and its characteristic orientating exactly has be

全球定位系统的先进性和实用性，其精确定位的功能特点已在各行各业中得到迅速的推广和应用，另一方面，传统的、功能单一的通信技术手段，已经不能适应多种业务发展的需要，因此，从运用先进的全球卫星定位与计算机技术，利用通信系统、多种先进技术集成以及实用性等方面设计集成综合信息系统很有必要。
