新质生产力是与产业高质量发展相契合的生产力,实现产业高质量发展离不开新质生产力的驱动。新质生产力与产业高质量发展存在相互促进关系,加快发展“战略性新兴产业”和“未来产业”是加快形成新质生产力的两大突破战略。江苏在培育新质生产力方面取得阶段性成果,但也存在产业发展谋划布局不充分、科研创新有短板、绿色发展水平待提高等不足。江苏培优做强新质生产力可以按照促进科技创新、推动改革创新和构建现代化产业体系这三重思路来布局,助力实现产业高质量发展目标。

放电凹坑大小影响着加工表面形貌的一致性,放电凹坑的凸起高度及凹坑表面的重铸层对加工表面质量有重要影响。文章基于短电弧-电化学复合加工方法,在直流与脉冲两种常用电源类型下对钛合金TC4进行单次放电实验,分析两种电源类型下的短电弧-电化学复合加工单次放电凹坑尺寸及影响规律;结合单次放电凹坑实验所采集到的波形与电弧放电过程仿真模型对电弧放电过程的等离子体放电通道变化进行研究。研究结果发现,直流与脉冲放电凹坑的尺寸与影响规律差异与电弧的断弧方式有关,不同的断弧方式对等离子体放电通道产生影响,直流电弧倾向于通过流体介质运动和极间距离改变进行断弧,而脉冲电弧通过脉冲后沿电压变化和极间距离改变进行熄弧。这两种断弧方式不仅影响了凹坑的尺寸形貌,也影响了断弧后的电化学腐蚀效果。

The sequence stratigraphy framework of Paleogene of Qikou Sag has been built in this paper. The evolution law of episodic subsidence in Qikou Sag has been expounded, with the analysis of the characteristic of sequence thickness, as well as the study of consedimental tectonic activity, subsidence history, paleogeomorphology and the coupling relationship among them. The faults controlling action was the dominant mechanism during rifting stage I , as the depression was the dominant mechanism during rifting stage III, which embodies a process from intense disparity fault depression to integral subsidence. Meanwhile, under the control of regional faulting and later stage depression, subsidence rate centers and paleogeomorphic concave centers are always corresponding to the sequence thickness centers, and the changes of subsidence centers and paleogeomorphology concave centers are consistent with the migration of thickness centers, which presents the restriction, coupling and response among them and clarifies the law that tectonic activity controls the basin fill by means of controlling the subsidence rate and paleogeomorphology from contributing factor angle. On this basis, the dynamic evolution of the composite pattern of structure-subsidence-deposition in the fault controlling actic region during the three rifting stages and their petroleum geological significance has been discussed.

This paper proposes a clustered trajectories anonymity scheme （CTA） that enhances the kano nymity scheme to provide the intended level of source location privacy in mobile event monitoring when a global attacker is assumed. CTA applies isomorphic property of rotation to create traces of the fake sources distributions which are similar to those of the real sources. Thus anonymity of each trajectory and that of the clustered is achieved. In addition, location kdiversity is achieved by dis tributing fake sources around the base station. To reduce the time delay, tree rooted at the base sta tion is constructed to overlap part of the beacon interval of the nodes in the hierarchy. Both the ana lytical analysis and the simulation results prove that proved energy overhead and time delay. our scheme provides perfect anonymity with improved energy overhead and time delay.

High electromagnetic shielding performance was achieved in the Mg-9Li-3Al-1Zn alloy processed by accumulative roll bonding(ARB).The microstructure,electromagnetic interference shielding effectiveness(SE) in the frequency of 30-1500 MHz and mechanical properties of the alloy were investigated.A model based on the shielding of the electromagnetic plane wave was used to theoretically discuss the EMI shielding mechanisms of ARB-processed *** indicate that the SE of the material increases gradually with the increase in the ARB *** enhanced SE can be attributed to the obvious microstructure orientation caused by ARB,and the alternative arrangement of alpha(Mg) phase and beta(Li)*** addition,with the increase in ARB pass,the number of interfaces between layers increases and the grain orientation of each layer tends to alignment along c-axis,which is beneficial to the reflection loss and multiple reflection loss of the incident electromagnetic wave.

针对某煤矿1208采区沿空留巷存在顶板压力大、矿压显现强烈、巷道变形大等问题,分析了1208工作面推进时顶板破断特征,确定切顶爆破的关键参数;1208工作面进行爆破切顶卸压后,可使初次来压步距减少13.9 m,动载系数下降0.5,同时,顶煤的大面积垮落也减少了28 m,使初次来压、初次放煤时间变短,来压强度减小,防止大范围悬顶垮塌的发生,避免支柱在大面积悬顶垮落时的冲倒风险。对钻孔的考察,在爆破切顶后8 m左右的范围内,钻孔的孔壁上有明显的裂缝;这些裂缝是由工作面的采动所致,彼此贯通。采空区内的顶煤悬挂在这些贯通的裂隙中,并随断层一起垮落,从而提高了煤层的回收率。
