为了满足数字摄像法能见度测量仪均匀光源的要求,提高半导体发光二极管照明的均匀性,该文提出一种基于数字图像分析技术的设计方法。首先测量单颗LED在模组区域的亮度分布,进而拟合分布函数,再运用多颗LED亮度叠加原理,计算出不均匀度最小的多颗LED阵列方式,或固定均匀度对应的最佳尺寸。对仿真数据和实测数据进行对比分析,结果表明,该文计算出的LED阵列方式,与单边阵列相比,均匀度显著提高,最高可达95%以上。

可再生能源配额制(简称配额制)是当前中国可再生能源政策由固定溢价补贴制向政府政策与市场机制共同作用过渡的目标机制。随着电力体制改革不断深化,可再生能源政策将直接影响电力供应链主体博弈行为,造成不同的政策效应。鉴于此,考虑以消费端为配额义务考核主体并引入惩罚函数,构建包含发电企业、消费端在内的两级电力供应链纳什均衡博弈模型。该模型设置了3种政策情景:固定溢价补贴制、配额制和2种政策并行双轨制。通过算例仿真重点分析配额、罚金参数变化对配额制下各博弈主体最优交易电量和绿证价格的影响。考虑到政策的福利效应,比较了3种政策情景下社会福利差异。结果表明:配额制下可再生能源交易电量和绿证价格随配额的增加呈现先递增后递减趋势,随罚金参数的增大而增大;3种政策情景下社会福利函数关于配额的增加呈现倒“U”型分布;随着可再生能源市场份额增长,2种政策并行双轨制下的社会福利水平优于2种政策单独实施下的福利水平。

Objective: To detect the serum Betatrophin level in patients with gestational diabetes mellitus (GDM), and to explore the relationship between Betatrophin level and disorders of glucose and lipid metabolism. Methods: 119 cases of GDM women in our hospital during August 2015 to March 2018 were selected as GDM group, 100 cases pregnant women with normal blood glucose were chosen as Normal control group. Serum level of Betatrophin, glucose metabolism and lipid metabolism between two groups were compared. Pearson test was used to evaluate the relationship between Betatrophin, glucose and lipid metabolism disorders in GDM pregnant women. Results: Serum content of Betatrophin in GDM group was significantly higher than that in Normal control group, levels of HbA1c, FINS and HOMA-IR in peripheral blood were significantly higher than those in Normal control group;contents of TC, LDL-C and Apo-B in peripheral blood were higher than those in Normal control group, contents of HDL-C, Apo-A1 were lower than those in Normal control group. Correlation analysis showed that serum level of Betatrophin in GDM pregnant women was positively correlated with the disorder of glucose and lipid metabolism. Conclusion: Abnormally high expression of Betatrophin in GDM pregnant women may be an important factor in promoting disorder of glucose and lipid metabolism.

通过烟草田间试验,探索钙镁磷土壤调理剂对红壤生境烟草生长及土壤理化性状的影响,为钙镁磷土壤调理剂的合理利用以及酸性红壤农田施肥技术提供理论依据。以当地主栽品种云烟K13为材料,设计4个钙镁磷土壤调理剂施用量梯度进行田间试验,分析了不同钙镁磷土壤调理剂施用量对烤烟产量、质量、经济效益及土壤理化性质的影响。结果表明,与处理CK相比,处理T1的叶片数提高0.96%,叶绿素含量显著提高2.82%;处理T1、T2、T3和T4的pH值分别提高3.09%、17.99%、16.63%和16.05%;有机质含量分别提高7.51%、2.91%、4.12%和16.03%;总植物碱分别提高30.54%、27.54%、7.19%和15.57%;氯含量分别降低30.00%、25.00%、35.00%和35.00%。农民习惯施肥配施钙镁磷土壤调理剂处理后,烟叶经济性状均优于对照,各处理产值均显著高于处理CK,其中T3最高,为92295.63元/hm^(2),农民习惯施肥配施钙镁磷土壤调理剂有利于提高土壤的pH值、有机质含量和全磷含量,改善土壤的酸度,增加土壤的蓄水蓄肥能力,增加土壤的磷素储备,从而提高烟叶的氮素营养水平和植物碱合成能力,增加烟叶的蛋白质合成能力以及增加烟叶的香气和刺激性。综合分析,农民习惯施肥配施1500~3000kg/hm^(2)的钙镁磷土壤调理剂为较优的施肥推荐。

With the rapid economic development, the imbalance of China＇s balance of payments gets sever gradually, especially in the continuous increase in the net errors and omissions, which even has exceeded the international alert line. Such scale of net errors and omissions have also presented the flaws of the custody of capital flows, leading to huge capital escape and hot money influx, which needs our attention.

Inflammatory myofibroblastic tumor (IMT) is a special type of mesenchymal tumors. The tumors can occur all over the body. The most common organs involved were lung, followed by mesentery, omentum, retroperitoneum, and pelvic cavity. But it occurs very rarely in the stomach. This article mainly reports a 10-year-old patient who complained of progressive dysphagia for 4 years. Esophagogram suggests esophageal achalasia. Abdominal CT examination revealed a huge mass with calcification in the cardiac region of stomach with metastatic lymphadenopathy. PET-CT was also performed that consistent with malignant gastric tumor with metastatic lymphadenopathy. Gastroscopy also indicated that there was a huge mass in the cardia that compressed the esophagus, and biopsy was performed to reveal chronic gastritis. Pathological analysis was performed after surgical exploration and tissue samples were taken out and the final pathology was consistent with inflammatory myofibroblastic tumors. The patient was not able to undergo surgical treatment, so crizotinib chemotherapy was used. After treatment, the patient's tumors were significantly reduced, and the effect was obvious. The patient is now in stable condition and continues to follow up. This article hopes to review the literature of imaging diagnosis of inflammatory myofibroblastic tumors through this case report, so as to improve the understanding of this disease.
