, 2015 濱海水層的水位受到潮汐變動之影響，多年來，一直是地下水領域研究重點之一，特別是針對水層幾何形狀效應、多層滲漏水層，及水層異向性等問題。本研究考慮具異向性的海岸滲漏含水層系統，其上層為非侷限含水層，下層為侷限含水層，中間夾著滲漏層。水層的東西兩側是感潮河川，水層的南側海岸緊鄰海洋，我們針對這種三側受潮汐影響的U型滲漏含水層，建立其地下水流的數學模式，並推導其水位變動的解析解。若假設水層為均質、等向、未滲漏系統，則前人研究所導得的許多解，皆可視為本解析解的特例。另外 ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Capacitive deionization (CDI) using activated carbon (AC) electrodes holds great promise for seawater desalination, yet its practical application is severely constrained by the intrinsic hydrophobicity of carbon surfaces. Herein, we propose a solid‐state superhydrophilic modulation strategy that physically wet‐mixes superhydrophilic MOF ...

, 2013 碩士水為人類不可或缺之資源，因於南臺灣豐枯不均極為嚴重。可靠水源不穩定，水庫淤積、地下水超抽導致海水入侵。缺乏大型蓄水設施蓄豐濟枯。導致目前枯水期必須部分仰賴移調農業用水甚至河川保育用水因應給予生活及工業用水。臺灣面臨八年來最嚴重的旱象造成限水上危機，也造成國家經濟重大衝擊。 本研究主要以不超抽地下水及不抽取地下水為指標原則，統計並推算出未來10年後南部地區各標的總缺水量及農業休耕用水方面以海淡水取代。使用LINGO最佳化模式軟體，由六個方案的目標問題及限制式估計出南臺灣各方案最佳耗資成本 ...

Haiyang yu huzhao伪雄鱼是由雌鱼性逆转而成的生理性雄鱼，在全雌鱼苗种的规模化繁育过程中有着至关重要的作用，但国内外对其精子活力的研究较少。为研究黄姑鱼伪雄鱼繁殖期精子活力及环境因子对其活力的影响，利用计算机辅助精子活力分析系统(CASA)对伪雄鱼的精子密度、运动率、寿命和运动速度等指标进行测定；并且设置不同的温度和pH梯度组，探究不同环境因子对伪雄鱼精子活力的影响。结果显示，伪雄鱼精子密度为(2.60~2.24)×1010个/mL；在繁殖期内，伪雄鱼精子密度呈逐渐下降的趋势，且在排精中期和晚期 ...

Zhejiang Daxue xuebao. Lixue ban, 2011 根据2009年春季（5月）和夏季（8月）对长江口的调查监测资料，研究了海水中溶解态重金属（Cu、Zn、Pb、Cd、As、Hg）的时空分布特征，探讨了其影响机理，并对其污染水平进行了污染评价.结果表明，各重金属的质量浓度、空间波动程度在春、夏季，表、底层均存在一定的差异；Cu、Hg的污染最严重，且夏季污染水平高于春季；Cu与Pb之间有显著的正相关性，Zn与盐度之间有显著的负相关性，其余重金属与盐度之间无显著的相关性；各重金属的平面分布可以分为沿岸条带状高值区、沿岸-离岸联片高值区、点源发散状高值区 ...

Journal of Research in Science Teaching, Volume 63, Issue 8, Page 771-799, October 2026.ABSTRACT Scientific modeling is the process by which students negotiate and peer review scientific models. This practice involves applying a set of criteria to evaluate the accuracy and validity of those models. However, previous studies have not adequately considered the role of different modes in facilitating such evaluation and revision.

Reframing Colonial Korea's Forests Through Protection Forests: The Forests of Joseon (1938)
Berichte zur Wissenschaftsgeschichte, Volume 49, Issue 3, Page 377-394, September 2026.This study examines The Forests of Joseon (1938), a forestry survey compiled by Tokumitsu Nobuyuki under Japanese colonial rule, as a key site of epistemic negotiation between imperial forestry science and Korean indigenous knowledge. Focusing on bíbo forests—geomantic forests believed to regulate energy flow between mountains and villages—the paper ...

Integrative Conservation, Volume 5, Issue 3, Page 281-292, September 2026.We comprehensively evaluated the seed plant diversity of Jiangxi province to address the regional biodiversity conservation of Asian subtropical evergreen broad‐leaved forests (EBLFs). Higher species diversity of seed plants was observed in eastern, southern, and western Jiangxi, with elevation and precipitation as mainly environmental factors.
