The authors have recently made two important improvements upon the wall pressure signature correction method for tunnel wall interference[1], which was originated by Dr. J. E. Hackett et al., Lockheed-Georgia Co. u.s.In original method, the wall pressure measurement has to be extended into the asymptotic range downstream of tested model, in order to obtain an accurate correction. Although this method was very convenient and applicable for various models and flow conditions, such a crucial requirement limited its application or decreased the correction accuracy. Here is presented a simplified method to have removed the measurement range problem above and obtained accurate correction in any cases. 2. For the pressure tests, an improved correction method is established in this paper, resulting in the coordinated correction approach for both pressure and force tests.The results from demonstration experiments on two sets of modes are presented also in this paper. It is shown that two important improvements removed the difficulty in practical application of original method, broadened the applicable range, and increased the correction accuracy in either force or pressure tests, '

本文介绍了对美国洛克希德公司Hackett,J.E.等人研究的壁压信息洞壁干扰修正方法两个重要的新改进。建立了一个简便方法,消除了原方法必须要在模型下游测到壁压的渐近分布,才能进行准确修正的苛刻条件;建立了一个测压试验洞壁干扰的改进修正方法,使测压与测力试验的修正方法一致。文中给出了两组模型的验证结果。本文的两个新改进,消除了壁压信息法应用中的突出难关,不仅拓宽了应用,并大为提高了测力、测压试验洞壁干扰修正的准确性。

A wall pressure signature correction method is developed to detennine the semiempirical correction factors suitable to the similar geometric model in a typical test attitude,in order to correct the wall interference on the model in other tested attitudes with a high angle of attack.In this way the correction procedure for the high angle of attack model tested is as easy and convenient as a semiempirical method,meanwhile it remains accurate enough comparing to the standard wall pressure signature method.The demonstrations...

提出用壁压信息洞壁干扰修正法,确定出大攻角典型试验状态的半经验修正系数,用它修正外形近似的模型大攻角试验其它状态的洞壁干扰。这样,模型大攻角试验的洞壁干扰修正既能接近壁压信息修正法的准确结果,又能如半经验修正方法那样简便。经两组模型试验数据验证,结果满意。

One hundred and forty─four male weanling Sprague Dawley rats weredivided randomly into two groups feeding AIN specifications diet, containing either<20μg or 800μg iron to set up iron─deficient or iron─normal rats respectively. Then, each group was further divided into two subgroups receiving either the same amount ofiron as control rats or 8000μg iron each day as iron─normal with iron supplementedand iron deficient with iron supplemented groups. In experiment Ⅰ,Ⅱ dietary zinc was30μg and 360μg respectively,...

One hundred and forty─four male weanling Sprague Dawley rats weredivided randomly into two groups feeding AIN specifications diet, containing either<20μg or 800μg iron to set up iron─deficient or iron─normal rats respectively. Then, each group was further divided into two subgroups receiving either the same amount ofiron as control rats or 8000μg iron each day as iron─normal with iron supplementedand iron deficient with iron supplemented groups. In experiment Ⅰ,Ⅱ dietary zinc was30μg and 360μg respectively, in experiment Ⅱ, the four groups rats fed <20 , 800, 8000μg iron each day respectively. Both of 1μCi ̄59Fe and 1μCi ̄65Zn were addedto the diet. Measurement included iron and zinc absorption at the first hour, next dayand the eighth day with whole body counter. The results showed that the absorption ofboth iron and zinc in iron─deficient rats was significant higher than iron─normal grouprats and the absorption of both iron and zinc reduced rapidly with iron supplemented. No changes of iron absorption in each groups with zinc dose from 30μg added to 360μg. Zinc absorption was reduced more and more with the increasing amount of ironfeeding in four subgroups rats.

SD纯品系断奶雄性大鼠144只,随机分为铁缺乏和铁正常两组。喂纯合成饲料,铁含量分别为<20μg与800μg,每日两次喂饲。两组模型建立后再各取一半大鼠每日补充钛剂8000μg,同前方式每日两次喂饲,另一半大鼠继续原方案不变,共建立铁缺乏补铁组、铁正常补铁组与铁缺乏、铁正常对照4个实验组。研究分3个实验进行,第Ⅰ、Ⅱ实验饲料中锌含量分别为30μg/d与360μg/d;第Ⅱ实验在4组模型建立后,每组大鼠再分为3组,分别喂饲1剂<20μg、800μg,8000μg3种不同铁含量饲料。在实验中将1μCi ̄59FeCl_3和1μCi ̄65ZnCl_2混合于铁饲料中喂饲,使用整体动物放射性测量仪测定1h和第2、8天的铁、锌吸收值。结果显示,铁缺乏组大鼠铁与锌的吸收率显著高于铁正常组,补铁后铁缺乏与铁正常组大鼠的铁、锌吸收率明显下降。饲料锌在30~360μg/d范围内变化时,各组大鼠的铁吸收无明显变化,锌吸收因补铁而出现明显差异。4组大鼠在分别喂饲1剂<20、800、8000μg铁剂后,锌吸收率随补铁量增大而明显降低。
