钦杭成矿带东段燕山期中酸性岩浆活动时空演化与成矿规律

作者： Danshi Zhu Yusi Shen Lingxia Xu xuehui Cao Changxin lv Jianrong Li College of Food Science and Technology Bohai University

In this paper, the browning and flavor changing of cloudy apple juice during accelerated storage were investigated with storage temperature at 37 ℃. These indicators, such as, soluble solids content, titratable acid content, Vc, color difference, and turbidity of cloudy apple juice were measured every 1 or 2 hours during storage. Meanwhile, the volatile flavor of juice were also analyzed using electronic nose. The results showed that L and ΔE values decreased during storage, while a and b values increased. The electronic nose could distinguish the apple juice stored for 0 hour from other storage time, and the sensor with the highest contribution rate was W1S, followed by W1C and W2S, which were sensitive to hydrocarbons, aromatics, and alcohols, respectively. The values of Vc content, sugar-acid ratio, and turbidity fluctuated slightly during storage. In general, the content of Vc decreased significantly, and the ratio of sugar to acid also decreased, while, turbidity increased during storage.

钦杭成矿带东段处于华夏地块与扬子地块的交接部位,其特殊的构造背景造就了其独特的岩浆事件与成矿作用。本文详细总结了燕山期中酸性岩浆时空演化与成矿规律,认为钦杭成矿带东段燕山期岩浆活动是连续的,可分为"两期四阶段":早期早阶段(180~160Ma)主要形成I型花岗岩,早期晚阶段(160~145Ma)形成I型、S型花岗岩,晚期早阶段(145~125Ma)以形成S型花岗岩为主(136Ma之后开始形成A型花岗岩),晚期晚阶段(125~100Ma)主要形成A型花岗岩。以东乡-德兴I型花岗岩带为岩浆活动中心,总体经历了从西往东,从I型→S型→A型的演化过程。按成矿专属性,将I型花岗岩分为两种类型:I_1型花岗岩以形成铜(金)铅锌铁多金属矿床为特色,I_2型花岗岩主要形成钨钼矿;将S型花岗岩分为三类:S_1型花岗岩主要形成钨锡钼矿床,高分异的S_2型花岗岩形成铌钽矿,S_3型花岗岩主要形成铅锌银铀矿床;A型花岗岩则具备I型、S型两种花岗岩的成矿特征。与岩浆作用一致,成矿作用也是连续的,可分为相应的"两期四阶段"。成岩成矿的时空演化过程主要受太平洋板块俯冲过程中动力条件变化的控制,导致不同部位的基底地层发生熔融,发生不同程度的壳幔相互作用。

为了解决当前的火焰识别算法中模型不紧凑、识别精度与效率较低等问题,提出一种基于显著性目标识别理论的轻量化火焰图像分割方法。该方法基于类U-net的编码器-解码器的架构,架构内部采用了显著性目标检测的方法,引入多层注意力机制,以分层的方式检测火焰目标。该方法在公开数据集上取得了较好的识别结果,且通过对比4种经典语义分割模型可知,交并比指标提升了5.70%~16.25%,F_(1)分数最高提升了10%,且该模型的平均绝对误差值也远远低于其他4种经典模型。表明该轻量化模型在火焰分割效果和运行速度上的指标最佳,有着较强的鲁棒性和有效性。
