Experiments on the effects of flood for agricultural crops were done in Zhumadian. corn was selected as the experimental material, and choosing 3 days, 5 days and 7 days submerged days and the jointing stage, tasselling stage for artificial irrigation respectively. The field was given conventional management. After harvest, we recorded various characters and production data, and then compared them with the controlled areas. Then analysis and assessment of the impact of main flood factors on the crops were built.

2在驻马店市驿城区申庄村进行农作物洪水影响田间试验，用玉米作为试验材料，选取3 d、5d、7d三个淹没天数和拔节期、抽雄期两个淹没阶段分别对其进行人工灌水，田间采取常规管理，在作物收获后对玉米的各个性状及产量数据做记录并和对照区进行对比，进而分析和评估洪水灾害发生时对农作物的影响情况。

Objective To develop a current model reagent of red blood cellin reverse ABO typing for ways and means.

BO血型是供、受血者必做项目，仅用单克隆试剂进行ABO正定型的试验结果不可靠［1～4］，需要采用ABO反定型试验来验证［3，4］。

Then, some conclusions about the capillary water movement were drawn by changing the cushion's height.

同时，在室内做了相关的毛细水上升的试验，观测试验数据并从中探讨了毛细水的上升规律。

By measuring the residual stresses of the cylinder of a cement ball mill in four cases,and the fatique crack spreading for the thermal treatment and the un thermal treatment test samples,the results showed that the heat treatment sample reduced the residual stress,enhanced the fatique strength and lowered the crack spreading speed.

对球磨机筒体的4种情况的焊件进行残余应力测试，并对进行热处理和未进行热处理的试件做疲劳试验及疲劳裂纹扩展测试。试验结果表明：经过热处理的试件，残余应力降低，疲劳强度提高，裂纹扩展速率降低，结构抗疲劳性能增强。不过从工程应用角度看，对于板厚为20～25mm的球磨机筒体而言，不进行焊后热处理也能保证足够的疲劳强度

The damage analysis of cracked turbine disk in the rocket engine is described. From a series of analyses, the causes of failure were reasoned through calculation and experiments, fatigue analyses which include stimulating vibration test and fatigue strength calculation were emphasized.

针对某火箭发动机涡轮盘在热试车中出现的裂纹故障，进行全面的分析，准确定位故障类型，以试验和计算分析给出合理的故障原因，重点是在疲劳分析方面所做的工作，包括振动模拟试验、疲劳强度计算，并根据疲劳强度分析结果提出改进方案。

To solve this problem we have done a lot of analysis tests, the use of solubilizer to increase the solubility of dye; dyeing process using soft water, and add the chelating agent to reduce the sodium sulphate caused by hardness, while improving, but you can not completely avoid the dyeing flowers and subsequently by a large number of trials found that there is a dye bath Fe3 +, Cu2 +, Zn2 +-induced dye accumulation of heavy metal ions such as lead-color flowers.

为解决此问题我们做了大量分析试验，使用增溶剂，增加染料的溶解度；染色过程中使用软水，并添加螯合剂来降低元明粉引起的硬度，虽有所改善，但不能彻底避免染花，后经大量的试验发现是染浴中存在Fe3+，Cu2+，Zn2+等重金属离子诱发染料聚集引起色花。
