为明确不同剂型的人工饲料对七星瓢虫成虫的影响,为进一步优化七星瓢虫人工饲料的制作方法提供参考,采用两种剂型(干湿分离和微胶囊)人工饲料对七星瓢虫成虫进行饲喂,测定取食频次、取食量、交配频次、产卵频率和产卵量。研究结果表明:七星瓢虫成虫对干湿分离饲料的平均取食频次(0.72头/min)显著低于对微胶囊饲料的取食频次(1.58头/min),但干湿分离饲料组七星瓢虫成虫的平均取食量(0.04 g/对)显著高于微胶囊饲料组(0.02 g/对);干湿分离饲料组和微胶囊饲料组的平均交配频次无显著性差异;干湿分离饲料组的平均产卵频率、产卵量分别为19.00%、23.40粒/头,显著高于微胶囊饲料组的1.00%、2.40粒/头。总体来看,七星瓢虫成虫对两种剂型的人工饲料均能取食,干湿分离饲料更优于微胶囊饲料。

目的:探讨流感相关性曲霉菌病(IAA)患者发病及预后的影响因素,以确定流感感染环境中侵袭性曲霉病的特定危险因素。方法:选取2014年1月1日—2019年12月31日肇庆市第一人民医院收治的383例流感患者作为研究对象,根据其是否患IAA分为病例组(26例)和对照组(357例),比较两组患者的一般情况、发病和预后特征。结果:病例组患者年龄大于对照组患者,差异有统计学意义(t=2.404,P<0.05);病例组患者慢性呼吸道疾病、心血管疾病患病率高于对照组患者,病例组有吸烟史的患者高于对照组患者,差异有统计学意义(χ^(2)=5.093,P<0.05);病例组患者呼吸衰竭、休克、多器官功能障碍综合症(MODS)、并发症发生率高于对照组患者,差异有统计学意义(χ^(2)=19.019、4.014,P<0.05);病例组患者病毒转阴率、治愈率低于对照组患者,差异有统计学意义(χ^(2)=16.780、34.774,P<0.05);病例组患者APACHEⅡ评分高于对照组患者,差异有统计学意义(t=6.552,P<0.05)。吸烟史是IAA发生的独立影响因素,有吸烟的患者比没吸烟的患者容易得IAA。IAA预后影响因素分析显示,死亡组患者吸烟史、并发症、呼吸衰竭、急性生理与慢性健康评分Ⅱ(APACHEⅡ)、心率(HR)、呼吸(R)、降钙素原(PCT)高于生存组患者,淋巴细胞、氧合指数低于生存组患者,差异有统计学意义(t=6.552、3.846、4.624、6.556、7.130、2.521,P<0.05)。结论:吸烟史是IAA发病的独立危险因素,吸烟的流感患者比非吸烟的患者易患IAA。生命体征不稳定、发生并发症、病情危重的IAA患者死亡风险可能更高。

Research of the Synchronous Detection for TWACS

Problems and solutions of popularization of accounting computerization

2011 Third Pacific-Asia Conference on Circuits, Communications and System

作者： Wenbing lu yingli luo Zhijun Liu The College of Electric and Electronic Engineering North of China Electric Power University

Synchronous detection is the key of the demodulation for Two Way Automatic Communication System（TWACS）, and needs to determine the existence of voltage distortion in the power noise. The reliable synchronization detection can not be achieved by traditional means of TWACS due to the strong interference in the industrial network. For this reason, the pseudo-random M sequence encoding is applied in this paper for the modulation of the synchronization information. The synthetic signals are generated according to the modulation code, and then the syndrome parameters are calculated by Short-window Fourier transform and cross-correlation technique. The quality of the synchronous detection in the poor industrial channel can be ensured by the sharp autocorrelation of the M sequence and the syndrome parameters.

With the integration of China's economy and international markets, accounting computerization, which conducts accounting and accounting control by taking advantage of computer, has become a major component sector of accounting modernization and the main content of accounting reform. The popularization of accounting computerization is beyond question. Only this popularization can meet the requirement of knowledge economy for accounting information. It is the need to deepen accounting reform, to further enhance the level of accounting work and to achieve China's modernization of science and technology as well. This paper discusses problems and relevant solutions in the popularization process of accounting computerization so as to carry out this popularization better.
