   甜菜種子帶銹病和褐斑病菌檢測方法的研究
2. Based on the design methods above , we research the possibilities of build nonuniform filter banks with linear phase in the third part , pointing out the difficulties may occur and bringing up our ideas
   第三部分，我們在上述兩種子帶濾波器組設(shè)計方法的基礎(chǔ)上，探討了構(gòu)造非均勻的線性相位濾波器組的可能性，指出了存在的困難，提出了構(gòu)造的設(shè)想。
3. In order to overcome the disadvantage of 2bps - 2 plastic film mulch seeder with watering apparatus that the operation speed is limited and the moisture evaporation loss is great , according to the theoretic analysis of water movement in soil , this paper offers another watering project - hidden watering under film , designs three different types of watering devices , meanwhile conducts test research with different watering devices in different position the change of the soil moisture content
   本課題針對2bps - 2型坐水鋪膜播種機坐水后，土壤水分蒸發(fā)損失大和機組作業(yè)速度低的突出問題，通過對水在土壤中運動的理論分析，提出了在行間膜下的暗道式施水方案，圍繞此方案設(shè)計了三種坐水部件，并就不同坐水部件在不同施水位置施水后，種子帶土壤含水量的變化進行了試驗研究。
4. On the basis of all these , the paper researches that the soil moisture content reduces slowly after 7 days ， so establishes a main criterion of evaluating watering feature - the increment of average soil water content in 7 15 days . according to these theories , we draw an conclusion - water is injected at the position away from seed zone 3 . 5 ( cm ) , 6 ( cm ) deep with vertical flat nozzle , the effect of watering is better at the operation speed of 0 . 9m / s
   得出7天后土壤含水量呈緩慢變化的趨勢，進而提出了以7 15天平均土壤含水量與初始含水量的差值作為評價坐水性能的指標，以此為依據(jù)得出在機組作業(yè)速度由0 . 5m / s增加到0 . 9m / s的情況下，采用豎扁（不帶翅）施水管將所需的水施到種子帶橫斷面內(nèi)3 . 5cm ，深6cm的位置，坐水效果較為理想。
