The precise correction of atmospheric zenith tropospheric delay(ZTD) is significant for the Global Navigation Satellite System(GNSS) performance regarding positioning accuracy and convergence time. In the past decades, many empirical ZTD models based on whether the gridded or scattered ZTD products have been proposed and widely used in the GNSS positioning applications. But there is no comprehensive evaluation of these models for the whole China region, which features complicated topography and climate. In this study, we completely assess the typical empirical models, the IGGtropSH model(gridded, non-meteorology), the SHAtropE model(scattered, non-meteorology),and the GPT3 model(gridded, meteorology) using the Crustal Movement Observation Network of China(CMONOC) network. In general, the results show that the three models share consistent performance with RMSE/bias of 37.45/1.63, 37.13/2.20, and 38.27/1.34 mm for the GPT3, SHAtropE and IGGtropSH model, respectively. However, the models had a distinct performance regarding geographical distribution, elevation, seasonal variations, and daily variation. In the southeastern region of China, RMSE values are around 50 mm, which are much higher than that in the western region, approximately 20 mm. The SHAtropE model exhibits better performance for areas with large variations in elevation. The GPT3 model and the IGGtropSH model are more stable across different months, and the SHAtropE model based on the GNSS data exhibits superior performance across various UTC epochs.

The process of crystal-melt separation in the high-silica magmatic mush is still a subject of debate. To explore the process， we conducted a detailed study of Late Miocene leucogranites (SiO2＞70 wt.%) in the Ramba Dome of the Tethyan Himalaya， focusing on the genesis and fluorine content of muscovite. The Ramba leucogranites consist of two-mica granite with minor garnet-bearing granite. Large and euhedral muscovites are found in both types of granite exhibiting different geochemical features. The muscovites from the two-mica granites exhibit lower F (mean value: ～0.41–0.43 wt.%)， FeO (mean value: ～1.75–1.81 wt.%)， but higher TiO2(mean value: ～0.61–0.73 wt.%) contents compared to those from the garnet-bearing granites (mean F value: ～0.72%; mean FeO value: 2.48 wt.%; mean TiO2value: ～0.23 wt.%). According to geochemical criteria， we categorized the muscovites from the two-mica granite as two groups: (1) crystallized from the early magma， and (2) formed from interstitial residual melt. In comparison， the muscovite from the garnet-bearing granite was likely crystallized from residual melt extracted from the same magmatic reservoir which underwent a higher degree of evolution. Accordingly， the two-mica granite represents the residual crystal mush consisting of early crystals crystallized from magma and trapped interstitial residual melt， while the garnet-bearing granite represents the aggregation of extracted residual melt. We examined the possibility of crystal-melt separation by estimating the variation of fluorine content and viscosity between the early magma and residual melt. Our results indicate a notable disparity in fluorine content between the residual melt (mean value: ～4364 ppm) and the early magma (mean value: ～2033 ppm). As a result， the estimated viscosity experiences a reduction from 106.52Pa s for the early magma to 105.87Pa s for the residual melt. The fluorine enrichment could have played a critical role in decreasing melt viscosity and initiating crys

面对“深度伪造”技术在信息制作上高度的以假乱真可能以及在色情领域的广泛存在,有必要明确刑法在深度伪造涉性信息规制上的立足点,将深度伪造涉性信息规制定位在“真实的性隐私保护”而非对“虚假信息”的打击。在信息流动的产业化背景下,网络与信息所形成的新秩序对传统刑法在隐私保护上构成挑战,现行刑法过于倚重前端预防的打击不力。在深度伪造治理公、私法融合的趋势下,深度伪造涉性信息犯罪规制范式必须转型,要从性隐私保护和信息规制两个层面对涉性信息进行检视,彰显“性隐私”的独立保护地位,肯定现实与虚拟交互中“性”利益保护的适度远程化,以“场景化”构建个人信息违法行为的刑法规制路径。同时,在深度伪造涉性信息制作、传播主体刑事责任的认定上,考虑涉性信息参与各方的风险防御可能,在性隐私保护上应当合理对伪造者、网络服务提供者以及受害人进行风险分配,以“合规”划定网络服务提供者的刑事责任边界;考虑个人信息主体在隐私保护上的同意“受限”,立法和司法应当避免单纯根据受害人的同意和创作者的“标识”对涉性信息制作和传播者以及平台等风险创设者进行免责处理。

现代汉语中,形式上无定的数量名短语也可用于回指。根据具体语用功能,数量名回指语可分为普通回指、内涵凸显型回指和数量凸显型回指。在不同回指用法下,数量名回指语在构成成分、句法位置和适用语境上表现出显著的内部差异。这些内部差异揭示出数量名回指语实际包含定指和不定指两种不同指称性质,且通过不同的方式实现回指确认。定指数量名回指语可实现普通回指和内涵凸显型回指用法,通过数量信息和名词属性与工作记忆中的已知对象进行匹配建立同指关系。不定指数量名回指语可实现内涵凸显型回指和数量凸显型回指,它们在话语中“伪装”为新信息,其与已知对象的同指关系为“会话含义”,需要听话人根据语境信息推理得出。

Carbonate rock chemical weathering carbon sinks reduce the rate of increase of the atmospheric CO_(2) concentration and global warming. However, uncertainty still exists in the estimation results of carbonate rock chemical weathering carbon sink fluxes(CCSF), and the contributions of climate change and ecological restoration to the CCSF are not clear. To this end, we compiled published site data on ion concentrations in different watersheds in China and used a classical thermodynamic dissolution model to reassess the potential and spatial and temporal patterns of the CCSF in China from 1991 to 2020. We quantified the contributions of temperature(MAT), precipitation(MAP), evapotranspiration(ET), soil water(SM), and the normalized difference vegetation index(NDVI) to the CCSF. The results revealed that(1) China's CCSF was 22.76 t CO_(2)km^(-2)yr^(-1), which was higher than the global average(15.77 t CO_(2)km^(-2)yr^(-1)). The total carbonate rock chemical weathering carbon sink(CCS) was 4772.67×10^(4)t CO_(2), contributing 14.91% of the global CCS through a carbonate rock area of 252.98×10^(4)km^(-2).(2) China's CCSF decreased gradually from southeast to northwest, with values of 33.14, 12.93, and7.27 t CO_(2)km^(-2)yr^(-1)in the southern karst, Qinghai-Tibetan karst, and northern karst regions, respectively.(3) The overall CCSF in China exhibited an increasing trend from 1991 to 2020, with a rate of increase of 0.16 t CO_(2)km^(-2)yr^(-1).(4) The contributions of the MAP, MAT, ET, SM, and NDVI to the CCSF were 63.3%, 3.02%, 27.5%, 3.1%, and 3.05%, respectively. Among them, the increase in precipitation was the main contributor to the increase in the CCSF in China over the last 30 years, while the enhancement of ET offset part of the positive contribution of the increase in precipitation to the CCSF. In conclusion, the results of this study provide a systematic quantification of the magnitude, the patterns, and the influencing factors of CCS over a long time series in
