The invention refers to a method to correct universal frequency of electric communication technique, its character: make signal index quantization on the complex number of cross product, to directly reflect the quantized numerical value of tangent value and the located quadrant of imaginary and real parts, use inverse tangent ROM table to discriminate the processed result, then make loop filter and phase accumulation on the discriminated result to obtain error-correcting angle, and use digital controlled oscillator to make table look-up and quadrant adjustment to obtain correcting factor; use the relationship of trigonometric function in each quadrant to compress inverse tangent look-up table ROM and digital controlled oscillator look-up table ROM.

一种涉及电通信技术的通用频率纠正的方法，其特征在于：它采用如下步骤：经过叉积的复数进行信号指数量化处理，通过该复数虚、实部信号的指数量化结果的差值及其极性直接反映虚、实部的正切值的量化数值以及所处象限，将处理后的结果通过反正切ROM表进行鉴频，鉴频后的结果经环路滤波和相位累加，得纠偏角度，通过数控振荡器针对纠偏角度进行查表和象限调整，得到纠正因子；通过个象限之间的三角函数关系来压缩反正切查表ROM和数控振荡器查表ROM的大小，本发明资源耗费小，效率高，可极大地节省内存资源。

Observe the effect of Fuling Gancao Decoction on gastric liquid emptying and content of nitric oxide and acetylcholine esteras in the gastric fundus,antrum and duodenal tissu of functional dyspepsia rats and investigate the mechanism.1 Reference reviewThe reference review discussed the source of disease name of TCM for FD,etiology and pathogenesis of TCM,selection of therapeutic methods by different stages or according to the differential syndrome diagnosis,advance on the clinical and experimental research as well as the problems lying in the research of TCM and corresponding strategies.We also have summarized the recent research progresses on the FD.In the meanwhile,we further exploited the pathologic characteristics,diagnosis and treatment of FD;summarized etiology and pathogenesis of TCM for FD and application of Classical Prescriptions in clinical and experimental study;Collected and arranged the Literatures and summarized the recent research progresses of Fuling Gancao Decoction;Finally, collected and arranged the literatures of proved cases and clinical experiences of Fuling Gancao Decoction.2 Theoretical studyThe Theoretical study first discussed the source of TCM for stomach deficiency and congestion of fluid-retention in syndromes of FD;Secondly, summarized the indications of Fuling Gancao Decoction,that is:①epigastric throb,②cold hands and feet in syncope,③hydroadipsia,④gastric blockade,⑤gastric splashing sound,⑥no desire for drinks,⑦light white tongue,thin-white and smooth fur,⑧deep and wiry pulse are the indications of Fuling Gancao Decoction;Subsequently,analyzed the composition of Fuling Gancao Decoction,considered that ginger is the main drug which treating congestion of fluid-retention in Middle-Jiao by Zhang Zhongjing.3 Experimental study3.1 Experiment oneObjective:To establish the animal model of FD with delayed gastric liquid emptying and evaluat it.

This may be explained by follows: First, Decoction Shenkangling can regulate the homeostasis of NEI network and reduce the increased activity of NF-κB to restrain the action of inflammatory-sclerotic media; Second, it can redress the disequilibrium of the ratio of TXA2/PGI2 to reform the hypercoagulable state; Third, it can enhance albumin and reduce cholesterol and triglyceride; Fourth, it can amend the renal damage and protect the function of renal tubule and stroma to prevent the transformation from MCD to FSGS; Last, it can lessen urine protein in AN rats markedly and relieve the side effects of prednisone.4. NF-κB, TXA2 and PGI2, along with the renal pathomorphology and so on can all be the indexes of the diagnosis of Symptom of "Kidney Deficiency and Blood Stasis" and the application of Methods of "Benefiting the kidney and Promoting blood circulation" in TCM.5. The curative effects on AN rats by treatment of integrating Traditional Chinese Medicine with prednisone are much better than using prednisone only. And the curative effects on AN rats by treatment of matching Decoction Shenkangling, having the function of "Benefiting the kidney and Promoting blood circulation", with Prednisone are much better than using Prednisone only.6. When it referred to decreasing urine protein, cholesterol and triglyceride and increasing albumin, Decoction Zhibodihuang excesses Decoction Taohongsiwu. However, when it referred to regulating the disequilibrium of TXA2/PGI2 and meliorating renal lesion, Decoction Taohongsiwu exceeds Decoction Zhibodihuang.7. The curative effects on AN rats by treatment of matching Methods of "Benefiting the kidney and Promoting blood circulation" with Prednisone overmatches using Prednisone matching Method of "Benefiting the kidney" or Method of " Promoting blood circulation" only.

益肾活血中药肾康灵能显著改善AN鼠的肾虚血瘀证的临床表现和实验指标，这可能与中药肾康灵能调理AN鼠机体的NEI网络功能稳态，降低异常升高的NF-κB活性，抑制免疫炎症/硬化介质环节，纠正失衡的TXA2/PGI2，改善AN鼠血液高凝状态，提高AN鼠的血清Alb，降低Ch和TG，减轻AN鼠的肾脏组织病理学变化，保护肾小管－间质功能，阻止MCD向FSGS转化；显著减轻AN鼠的尿蛋白水平以及减轻激素副作用有关。4、NF-κB、 TXB2和6-keto-PGF1α以及肾脏病理形态学改变等，都可作为中医肾虚血瘀证诊断和益肾活血法应用的客观指标。5、中西医结合干预AN鼠疗效优于单纯激素治疗；强的松配合益肾活血中药肾康灵组的综合疗效显著优于单纯强的松组。6、知柏地黄汤组在降低尿蛋白、提高血清Alb、降低Ch和TG疗效上优于桃红四物汤组；桃红四物汤组在纠正失衡的TXA2/PGI2和减轻肾脏病理损害方面优于知柏地黄汤组。7、激素配合益肾活血法干预AN鼠在一定程度上优于激素配合益肾法或活血法。
