介绍了一种应用扩展Kalman滤波技术估计车辆行驶状态的控制算法。该算法以非线性三自由度车辆模型为基础,对汽车在行驶过程中的横摆角速度、纵向车速和质心侧偏角分别进行了估计。为验证该算法的准确度,将估计获得的状态值与实车场地实验测得的数据进行了比较。比较结果说明,应用扩展Kalman滤波算法能够较为准确地估计出车辆的横摆角速度、纵向车速和质心侧偏角。

To the editor:The impact of the coronavirus disease 2019(COVID-19)pandemic in 2020 on mental health was substantialin Chinai2and various other countries.34 Beyond the direct consequences of COVID-19,the pandemic created an environment in which many determinants of mental health were *** associated with the pandemic,such as loss of livelihood,limited access to medical services,reduced social interactions,and economic downturn,could potentially have adverse effects on the population's mental well-being.5 In November 2021,the World Health Organization(WHO)designated the new variant of the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),variant B.1.1.529,as a variant of concern and named it Omicron;its rapid mutation and spread raised a new global health concern.

目的了解国内主要地区医院临床分离菌对常用抗菌药物的耐药性。方法国内主要地区12所教学医院(10所综合性医院,2所儿童医院)临床分离菌采用K-B法按统一方案进行抗菌药物敏感试验。按CLSI2007版判断结果。结果2007年1—12月收集各医院临床分离株共36001株,其中革兰阳性菌占34.3%,革兰阴性菌占65.7%。金葡菌和凝固酶阴性葡萄球菌中甲氧西林耐药株平均为58%和77%。大肠埃希菌、克雷伯菌属(肺炎克雷伯菌和产酸克雷伯菌)中产ESBLs株平均为55%和45%。葡萄球菌属中甲氧西林耐药株对β内酰胺类抗生素和其他抗菌药的耐药率显著高于甲氧西林敏感株,但仍有约60%～80%的菌株对磷霉素、复方磺胺甲口恶唑或利福平敏感,未发现对万古霉素、替考拉宁和利奈唑胺耐药株。肠球菌属中粪肠球菌对多数药物的耐药率低于屎肠球菌,但后者对氯霉素的耐药率仅6%。粪肠球菌对呋喃妥因和磷霉素的耐药率均低于10%。两者中均出现少数对万古霉素和替考拉宁耐药株,经PCR检测27株VRE均系VanA型耐药。大肠埃希菌、克雷伯菌属(肺炎克雷伯菌和产酸克雷伯菌)、奇异变形杆菌中产ESBLs株对抗菌药的耐药率均比非产ESBLs株高。流感嗜血杆菌和卡他莫拉菌的产酶率分别为27.4%和96.1%。肺炎链球菌儿童分离株中青霉素不敏感株显著高于成人分离株,两者分别为88.5%和26.4%。肠杆菌科细菌对碳青霉烯类仍高度敏感,总耐药率<1%,其次为阿米卡星、头孢哌酮-舒巴坦。铜绿假单胞菌对亚胺培南、美罗培南耐药率分别为36%和28.5%,不动杆菌属对两者的耐药率分别为35%和40%。米诺环素对嗜麦芽窄食单胞菌、伯克霍尔德菌有良好活性,两者的耐药率均低于5%,值得注意。不发酵糖革兰阴性杆菌对抗菌药物的耐药率均显著高于肠杆菌科细菌,以对头孢哌酮-舒巴坦的耐药率最低。在多数医院中均出现泛耐药革兰阴性杆菌,以铜绿假单胞菌、鲍曼不动杆菌较多,尚有少数肺炎克雷伯菌和弗劳地柠檬酸杆菌。结论细菌耐药性仍呈增长趋势,尤其肠球菌属中VRE和革兰阴性杆菌中多重耐药株和泛耐药株有所增多,各医院采取有效控制措施刻不容缓。

To investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sample, distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII collider in the year 2010. By analyzing the large angle Bhabha scattering events, we measure the integrated luminosity of the data sample at each center-of-mass energy point. The total integrated luminosity of the data sample is 76.16±0.04±0.61 pb^-1, where the first uncertainty is statistical and the second systematic.
