Recent submillimeter dust thermal emission observations have unveiled a significant number of inter-arm massive molecular clouds in ***,the effectiveness of this technique is limited to its sensitivity,making it challenging to study more distant *** study introduces an alternative approach,utilizing optical extinctions derived from space-based telescopes,with a focus on the forthcoming China Space Station Telescope(CSST).We first demonstrate the capability of this method by constructing dust extinction maps for 17 inter-arm massive molecular clouds in M31 using the Panchromatic Hubble Andromeda Treasury *** analysis reveals that inter-arm massive molecular clouds with an optical extinction(A_(V)) greater than 1.6 mag exhibit a notable A_(V) excess,facilitating their *** majority of these inter-arm massive molecular clouds show an A_(V) around 1 mag,aligning with measurements from our JCMT *** validation using a mock CSST RGB star catalog confirms the method's *** show that the derived A_(V)values using CSST z and y photometries align more closely with the input *** clouds with A_(V)> 1.6 mag can also be identified using the CSST mock *** thus claim that future CSST observation clouds provide an effective way for the detection of inter-arm massive molecular clouds with significant optical extinction in nearby galaxies.

目的:探讨智能手机应用程序(App)头影测量数据的准确性。方法:选取55例患者的头颅侧位片,分别使用电脑软件和智能手机App测量12个项目。采用组内相关系数(ICC)分析测量方法的可靠性,配对t检验比较2种方法测量结果的差异。Bland-Altman法计算测量结果差值的95%一致性界限(LoA)的95%可信区间(CI),以评价2种测量方法的一致性。结果:2种方法所有项目的重复测量ICC值均大于0.9。2种方法各项测量数据的比较均无显著差异(P>0.05)。除U1-NA、L1-NB和U1-L1外,SNA、SNB、ANB、SN-MP、Y-Axis、U1-NA(mm)、L1-NB(mm)、UL-E line及LL-E line测量差值的95%LoA的95%CI均在临床可接受范围内。结论:智能手机App与电脑软件的骨性及软组织头影测量数据具有较好的一致性。智能手机App作为一种便携、准确、可靠的方法,可在头影测量中推广应用。

采用原位合成法制备Cu-Cr-Zr合金,并对时效试样进行显微硬度、电导率及耐磨性能测试,研究结果表明,80%冷变形处理后最大电导率比初始电导率提高约一倍,变形量越大,合金的电导率越高,冷加工态的试样在500℃以下时效处理时,对导电率的影响十分明显,而对硬度的影响较小。合金材料的磨损试验表明,不带电磨损的机制主要为粘着磨损,带电情况下磨损机制主要为磨粒磨损。
