A non-linear digital image edge detection method has been proposed in this paper. Based on the magnitude of ΔT1 which is the gray level difference between the central pixel's and the pixels's in its δ neigborhood, the set of ΔT1 would be divided into two same subsets, and for each subset the average levels and are obtained with non-linear weight coefficients A (ΔT1). The edge value is defined as With this response of edge detection, not only could weaker edges be detected, but the effect of noise could be eliminated....

In the later part of this paper, an appreciate parameter S is pointed out, which can be used reasonbly to evaluate the results of edge detection methods.

本文提出了一种数字图象边缘检测的非线性代数方法。克服了常用方法对不同强度边缘进行检测时易丢掉弱边缘的弱点,并有效地抑制了噪声的影响。首先对中心象元与其δ邻城内各象元灰度差△T_i按其大小分成两相等的集合,再据一非线性加权系数A(△T_i),求得各集合的平均灰度差△T_i(i=1,2),定义边缘值为|△T_1-△T_2|。另外在本文的后一部分,提出了一个用来评价各种方法检测效果的指标一优质系数R,它比较客观、准确。

Status of soil phosphorus and rational application of phosphorus fertilizer were studied by field trials. Results abtained showed that (1) variation of soil total P and available P contents were both increasing from the north to south and the contents of different soils were in the following order: irrigation warped soil>manured loessial soil, cinnamon soil, dark loessial soil>yelow cultivated loessial soil, sieroezm, chestnut soil>aeolion sandysoil; (2) contents of available P were divided into five levels (P-ppm):<2.0 (very low), 2.0—5.5 (low), 5.5—10.5 (medium), 10.5—20.0 (high), >20.0 (very high). Meanwhile the corresponding yield increment with phosphorus fertilizer applied were 72, 36, 25, 10, 3% respectively; the probability of yield increase from. phosphorus fertilizer applied were 100, 100, 86, 56,0%. Resulits pointed out that the crtical value of sorl available-P is 5.5 ppm; (3) it is suggested that the content of organic-P and inorganic-P/organic-P raio of soil may be the one of the fertility intexes of soil. Content of O-P and Ca-P/O-P ration of soil can provid the division for the degress of soil weathering; (4) The general tendency of respomse to P fertilizer application were soils of low and medium fertility>those of high fertility, irrigated soils>non-irrigated soils, and the application of P fertilizer combined with N fertilizer was better than single application of P fertilizer.

黄土地区土壤中全磷与有效磷含量均有由北向南逐渐趋增的趋势,一般是:灌淤土较高,(土娄)土、褐土与黑垆土次之,黄绵土、灰钙土和黑钙土又次之,风沙土较低。土壤有效磷可分为4级,5.5ppm可作为土壤缺磷临界值,5.5—10.5 ppm作为边缘值。黄土地区土壤中各形态磷占全磷比例以Ca-P最高,有机磷与O-P次之,Al-P、Fe-P和水溶磷较低。土壤有机磷及其与无机磷的比值与土壤肥力有密切关系,闭蓄态磷及其与磷酸钙的比值似与土壤风化程度有关。磷肥施入土壤后,早期固定较快,20天后渐趋平稳。在高钙土壤中,施入的磷主要转化为Ca-P,低钙土壤则转化为Ca-P,Al-P和Fe-P。黄土地区磷肥施于低肥土壤或中肥土壤中其肥效优于高肥土壤;施于灌溉土壤优于旱作土壤;与氮肥配施优于单施。

Objective:To evaluate application of a serial measurement of airway occlusion pressure (P 0.1 ) combined with traditional weaning parameters in prediction weaning from mechanical ventilation.Methods:During weaning from pressure support ventilation (PSV),P 0.1 was measured per eight hours in patients with respiratory failure needing mechanical ventilation.V T,V E,RR,E TCO 2,SpO 2 and pressure support (PS) levels were recorded simultaneously in these patients.Patients were divided into two groups: successful weaning group (24 cases) and failure weaning group (16 cases).Results:During PSV,P o.1 ,V E in successful group were not markedly changed ( P >0.05).In failure group,P o.1 of perend value (0.75±0.36kPa,1kPa=10.20cm H 2O) was significantly higher than that of basal value (0.41±0.28 kPa),and also those of successful group (0.27±0.09 kPa,0 28±0 15kPa, all P <0.01).Similarly,V E in failure group was significantly higher than that in successful group ( P <0.05).A significant correlation was found between P 0.1 and V E ( r =0.62, P <0.05).Conclusions:P o.1 has been shown to be a predictor for the ability of ventilated reserve.Decision of weaning from marginal value of conventional parameters combined with a serial measurement of P 0.1 would significantly increase successful rate of weaning from mechanical ventilation in patients.

目的:探讨动态监测气道闭合压(P0.1)在预测成功脱机中的应用意义。方法:各种呼吸衰竭需要机械通气患者在应用压力支持通气(PSV)脱机时,每8小时测定1次P0.1,同时记录患者的潮气量(VT)、通气量(VE)、呼吸频率(RR)、潮气末二氧化碳分压(ETCO2)、经皮血氧饱和度(SpO2),以及压力支持(PS)水平,将患者分为脱机成功组(24例)和脱机失败组(16例)进行对照分析。结果:在PSV期间,脱机成功组P0.1、VE均无明显变化(P>0.05);脱机失败组P0.1结束前值(0.75±0.36kPa,1kPa=10.20cmH2O)与基础值(0.41±0.28kPa)以及与脱机成功组同期值(0.27±0.09kPa,0.28±0.15kPa)比较均明显升高(P均<0.01),VE较脱机成功组明显升高(P<0.05)。P0.1与VE明显相关(r=0.62,P<0.05)。结论:动态观察P0.1,对于常规参数处于边缘值欲脱机患者将可明显提高脱机成功率。
