作者： Jinzhong Cui Ping He Fenghong Liu jingjing tan Lingfeng Chen Joshua Fenn Institute of Botany Chinese Academy of Sciences

In celebration of JIPB＇s 60th anniversary, this paper summarizes and reviews the development process of the journal. To start, we offer our heartfelt thanks to JIPB＇s pioneer Editors-in-Chief who helped get the journal off the ground and make it successful. Academic achievement is the soul of academic journals, and this paper summarizes JIPB＇s course of academic development by analyzing it in four stages： the first two stages are mostly qualitative analyses, and the latter two stages are dedicated to quantitative analyses. Most-cited papers were statistically analyzed. Improvements in editing, pub- lication, distribution and online accessibility--which are detailed in this paper--contribute to JIPB＇s sustainable development. In addition, JIPB＇s evaluation index and awards are provided with accompany- ing pictures. At the end of the paper, JIPB＇s milestones are listed chronologically. We believe that JIPB＇s development, from a national journal to an international one, parallels the development of the Chinese plant sciences.

针对大部分轨迹相似性度量算法无法区分方向相反轨迹的问题,提出了一种基于三维空间面积划分的三维三角分割(3TD)算法。首先,按照3TD算法的时间转换规则将轨迹集的绝对时间序列转变为相对时间序列;然后,在由经度、纬度以及时间三要素构成的三维空间坐标系中,通过划分规则将轨迹间面积分割成若干互不重叠的三角形,累加三角形面积并计算轨迹相似度;最后,在从船舶自动识别系统(AIS)收集的随机采样轨迹数据集上,与最长公共子序列(LCSS)算法和三角分割(TD)算法等进行了对比实验。实验结果表明:3TD算法对实验数据集中异向轨迹识别精确度达到100%;同时该算法面对海量数据集以及轨迹点部分缺失的数据集时,也能维持准确的度量结果以及较高的运算效率,能更好地适应异向轨迹相似度量工作。

本文研究了UHPC中掺入钢纤维和混杂纤维对其力学性能的影响,试验表明:UHPC在掺入钢纤维体积分数1.5%的基础上,外掺了体积分数均为0.5%的钢纤维、聚乙烯醇纤维(PVA)和聚丙烯纤维(PP)后,其抗压强度变化不大,其抗折强度依次增大,外掺了聚乙烯醇纤维的抗拉强度最大。相同体积分数的纤维掺量,由于有机纤维的密度较小,故其质量相应地减少,从而费用也相应地减少。

The non-stoichiometric Li_(3)Mg_(2)Sb_(1-x)O_(6)(0.05≤x≤0.125)compounds have been prepared via the mixed oxide method.The influences of Sb nonstoichiometry on the sintering behavior,microstructure,phase composition along with microwave dielectric performances for Li_(3)Mg_(2)Sb_(1-x)O_(6) ceramics were studied.Combined with X-ray diffraction(XRD)and Raman spectra,it was confirmed that phase composition could not be affected by the Sb nonstoichiometry and almost pure phase Li_(3)Mg_(2)SbO_(6) was formed in all compositions.Appropriate Sb-deficiency in Li_(3)Mg_(2)SbO_(6) not only lowered its sintering temperature but also remarkably improved its Q×f value.In particular,non-stoichiometric Li_(3)Mg_(2)Sb_(0.9)O_(6) ceramics sintered at 1250℃/5 h owned seldom low dielectric constant ε_(r)=10.8,near-zero resonant frequency temperature coefficient τ_(f)=-8.0 ppm/℃,and high quality factor Q×f=86,300 GHz(at 10.4 GHz).This study provides an alternative approach to ameliorate its dielectric performances for Li_(3)Mg_(2)SbO_(6)-based compounds through defect-engineering.

The most effective treatment for postoperative pain is to reduce it by preventing or reducing the sensitivity and sensory disturbance on the central nervous system during the operation,prolonging the pain-relief time and reducing the use of analgesics.Preemptive analgesia refers to the intervention of central neuraxis sensitization and peripheral sensitization to prevent the expansion and spread of pain,so as to achieve postoperative pain-relief.In postoperative patient-controlled analgesia,preemptive analgesia has become a common treatment method for anesthesiologists.However,the clinical specifications for advanced analgesia are still lacking.Based on this,this paper reviews the use of advanced analgesia drugs and their clinical applications.
