21世纪中国话剧舞台上的“宏大叙事”仍然以对革命历史题材作品的演绎为主,先后出现了多部以纪念革命历史、重温革命记忆、传承革命精神、弘扬革命文化为题旨的舞台精品剧目。剧作者/导演普遍以“情感表达”作为切入革命历史题材的方法与策略,凭借对革命历史的“在场性”叙述与革命英雄的“人性化”塑造,完成了对先前剧目题旨内容趋同现象与排演模式固化问题的突破。这些基于“人文立场”与“微观视角”的创新对今后同类题材话剧的创排提供了以资借鉴的经验。

针对钻井过程复杂振动环境下单独使用加速度计和陀螺仪都无法准确获得近钻头处工具面角测量值的情况,提出一种融合单轴陀螺仪和双三轴加速度计测量数据的组合滤波方案。采用扩展卡尔曼滤波算法,根据加速度计测量信息自适应地调整滤波参数使测量结果最佳,能够准确估计出工具面角和陀螺仪漂移。仿真与实际测试结果表明,该方法能够适应钻井工具不同运行工况并大幅减弱井下振动、陀螺仪漂移等因素对工具面角动态测量精度的影响,工具面角误差小于6°,为旋转导向钻井工具的研制奠定了基础。

为了研究施加不同浓度的生物炭对丛枝菌根真菌(arbuscular mycorrhizal fungi,AMF)共生体系下玉米根系及生长的影响,选用玉米正大619以盆栽方式进行试验,设置0%(CK)、0.75%(C1)、1.50%(C2)、2.25%(C3)、3.00%(C4)5个不同的生物炭施用量和3个取样期(玉米出苗30、50、70 d)。结果表明,施加生物炭显著降低30、50 d时玉米根系的侵染率(P<0.05)、降低30 d时的接种势和基质孢子数;提高玉米叶片叶绿素含量(50 d时的C1、C2处理除外);施加生物炭处理在30、50 d时玉米根系指标相比同时期的对照主要表现为下降,而在50 d时C2、C3处理的根系指标则高于对照;施加生物炭提高了30、70 d时的根系活力(30 d时的C3处理除外),而50 d时由于侵染率较低且根系生长相比其他2个时期较弱,因此根系活力较低;30、50 d时,施加生物炭显著提高玉米地上部和地下部干质量(30 d时的C3、C4处理及50 d时的C4处理除外),而70 d时玉米处于开花期,对养分需求量较大,C1、C2、C3处理因菌根侵染率较低,根系生长状况不及CK,因此干物质积累较少,而C4处理在高浓度的生物炭作用下保障了养分供给,使玉米干质量高于CK(P<0.05)。生物炭的施加会抑制菌根和玉米根系的生长,但生物炭改善土壤理化性质和养分含量,保证养分供给,因此提高了玉米的叶绿素含量和干质量。
