为研究液相等离子体电解渗过程中施加的工作电压与工件表面温度的关系,建立了以工件—气膜—电解液三相体系为研究对象的热传导物理模型。等离子电解处理时,工件表面被一层连续而稳定的等离子体气膜所包围,气膜将工件与电解液分开,气膜与工件边界的温度即为工件表面的温度。建立气膜的热传导方程,采用第一类和第二类边界条件求解气膜中的温度分布,从而得到工件表面温度计算的表达式。实际测量了不同工作电压时工件的温度,理论计算的工件表面温度与实验测温结果都表明,随着工作电压的增大,工件表面温度不断增加。当温度计算模型中的气膜热导率是温度的函数、气膜电导率为常数的条件下,理论计算结果与实验结果符合程度最好。

Dear Editor,Targeted genome-editing technology using designed nucleases has been rapidly advancing and catalyzing significant breakthroughs in the life ***-designed CRISPR editing experiments can be efficiently evaluated through nextgeneration sequencing(NGS).Nevertheless,NGS data analysis currently lacks a user-friendly pipeline capable of automatically calculating mutations and evaluating editing efficiency in bulk,as well as providing a more comprehensive visualization of results.

Nitrogen-doped diamond films have been synthesized by EA-CVD （electron assisted chemical vapor deposition） technique. The quality and nitrogen impurity states of the diamond films are characterized by SEM, raman spectroscopy, XPS and EPR speclroscopy, respectively. The results show that the morphology changes from well-defined facets to cauliflower-like structures, the content of amorphous carbon increases and the quality drops with increasing the nitrogen flow rate. Furthermore, in the films, it can be observed that nitrogen impurity exists in the forms ofNs^0, [N-V]^0 and [N-V]^1. The contents of [N-V]^0 and [N-V]^-1 are lower when the nitrogen flow rate is relatively high, and the concentration of Ns^0 varies from 15 ppm to 483 ppm.

Desertification has been caused by various factors and is a major environmental problem and development bottleneck faced by the world. It is also a serious threat to ecological security and to sustainable economic and social development. As a stubborn world problem, focused on by the United Nations 2030 sustainable development goal 15.3, China aims to combat desertification by implementing the "eight-column fourbeam" strategy, and also suggest the "four-medicine"approach for global desertification governance. This includes the development of the United Nations Convention to Combat Desertification protocol, unified global compliance and compliance metrics; building a global observation network, and monitoring land changes based on remote sense; preparing the global natural desert(heritage) list, leaving the original deserts for future generations; initiating the global action of combating desertification, and striving to achieve a land degradationneutral world by 2030.

Accurate aerodynamic measurements in the hypersonic flow of large aircraft models in tunnels have practical significance, but pose a significant challenge. Novel aerodynamic force measurement methods have been proposed,but lack theoretical support. The forms of the force signals techniques for signal processing and calculation of aerodynamics are especially problematic. A theoretical study is conducted to investigate the dynamic properties based on models of the draw-rod system and slender rods. The results indicate that the inertia item can be neglected in the rod governing equation;further, the solutions show that the signals of each rod are a combination of aerodynamic signals（with a constant value） and sine signals, which can be verified by experimental shock tunnel results. Signal processing and aerodynamics calculation techniques are also found to be achievable via the flat part of the signals.
