With the development of computer and graphics technology, the advanced dashboard of an aircraft has brought about a great challenge to the quality of the graphics.Based on the cause of the aliasing, the thesis below puts forward a new method using Gaussian Integration to get rid of it and offers detailed mathematical deduction as well. Furthermore, the practical generation of rhumb lines has proved the effectiveness of the new method

随着计算机及图形学技术的发展，座舱仪表对图形显示的质量提出了更高的要求，本文主要从图形走样产生的根本原因出发，提出利用高斯积分法来消除走样现象，且给出了较详细的数学推导，并将此算法应用于罗盘刻度线的生成，效果比较明显。

Tian Han said, in general, the composition of groups of foreign nationals, including embassy personnel, foreign investors and senior management personnel, because a few years working in China will be the rotation group of people, so they usually do not buy a house, together with high subsidies, so they tend to rent with the families of high-quality, expensive high-end rental apartments; At the same time, some senior managers in foreign invested enterprises, desire to live in an atmosphere of high-quality, independent apartment of this overall environment has also shown very strong interest.

In this paper, as a case of Karamay, we have studied on space-time changement of soil quality in oasis of arid area. We measured quality for different land use types and years in same type by combinativing field sampling for Karamay in Xinjiang and analysis in laboratory, which is directed by former theory of soil quality. Then we did integrated evaluation of soil quality for different land use types, and had drew some conclusions as followed: In four land use types, the soil bulk density of layers(0～15cm) for farmland and tree land is bigger than the other land use types.The organic matter of every layer in manpower Tamarix Bulrush land is bigger; organic matter of Tamarix Bulrush land release efficiency nitrogen which result ration of C/N is higher; total nitrogen of all layers in farmland variety great as being effected by mass use of nitrogen in agriculture; deadwood and defoliation of tree、shrub and bulrush pooled in 5cm layer to result that quick nitrogen is the biggest among all layers. The total salt of nature shrub tree land for every layer being bigger than farmland explain that nature shrub thee land strongly stand salt and farmland for basification in this area; that the nutrient of face layer is bigger than the ground layer may be explained by that vegetation gather nutrient to be stored in deadwood and defoliation.

本文对以克拉玛依为例，对干旱区绿洲土壤质量的时间空间变化进行研究，在有关土壤质量的研究理论指导下，通过田间调查取样和室内分析相结合的方法，对新疆克拉玛依市农业开发区的不同土地利用方式及同一土地利用方式下不同利用年限土样土壤理化性质进行测定，从而对新垦绿洲不同土地利用类型土壤质量进行综合评价，结果如下：四种土地利用方式中，农地、乔木林地表层(0-15cm)土壤容重较大；各土层人工柽柳芦苇地的土壤有机质含量均较大；柽柳芦苇地的有机质在矿化过程中所释放出有效氮，导致柽柳芦苇地的C/N比例较高；受到农业耕作使用大量氮肥的影响，农地各土层全氮含量变异较明显；乔木、灌木及芦苇的枯枝落叶主要集中在5cm范围之内，导致几种土地利用方式类型下该层土壤速效氮最大；天然灌木林地的土壤总盐在各层均较大，其次是农地，说明天然灌木林地的高耐盐能力，以及该区农业生产用地的土壤盐碱化程度较重。

Fertile and sterile pools were set up by bulked segregant analysis based on the selection for the highly fertile and highly sterile plants of Shanyou 63 F_2 populaiton The AFLP analysis of the two pools indicated that 64 primer combinations amplified 3 477 stable and clear bands.

选择汕优63F_2的高可育株和高不育株分别建立 2个基因池，利用 AFLP标记技术对2 池间的多态性进行了研究。分析表明，64组引物在两池间全部扩增出了稳定、清晰的带纹，共计3 477条带。

Usually, kicking other's upstairs is a good method to fire the executives. It seems like investigating corrupted officials, which begins with pulling you out of your old base and offering you a promotion (certainly, as a deputy head without real power or taking a sinecure) and ends up with investigating your misdeed by the man they trusted.

通常明升暗降是炒高管的技巧，这种手段类似于查贪官，先把你从自己的"老根据地"里拔出，晋升一级(当然，不消说，肯定是一个位高没权的副职或者闲职)，然后派入信得过的自己人，查你以前的劣迹。

由于使用了高爆燃烧曳光弹，石龙子在对建筑物进行射击时体现出了极高的价值，可以迫使敌军离开建筑去到开阔地域。

This experiment adopts artificial simulation research approaches, namely using the standardized moisture stress conditions with hypertonic solution to immerge rubber tree seeds during germination to elementarily select out some rubber seedlings, which could stand the high-osmosis stress. The germination characteristic of the rubber tree seed under high-osmosis stress was observed and the phenomena of growth and dynamic changes of physiology and biochemistry were determined and analysed, and then its ability of drought-resistance was valued.

本试验采用人工模拟研究方法，利用高渗溶液提供标准化的水分逆境条件，对催芽过程中的橡胶树种子进行人工胁迫处理，并筛选出耐高渗胁迫的橡胶籽苗，观测种子的萌发特性和选出籽苗的生理生化特性并对其抗旱性作出评价。
