“directly proportional”（直接成比例）是一个数学与科学领域的术语，用于描述两个变量之间的一种线性关系。当两个变量满足“directly proportional”时，意味着其中一个变量随另一个变量的增减而按固定比例同步增减。具体来说，若变量( y )与变量( x )直接成比例，则存在一个非零常数( k )，使得关系式可表示为： $$ y = kx $$ 其中，( k )称为比例常数。例如，在物理学中，根据胡克定律（参考《物理学基础》教材），弹簧的伸长量( Delta L )与施加的力( F )直接成比例，即( Delta L = kF )，其中( k )为弹簧的劲度系数。
这种关系在工程学、经济学等领域广泛应用。例如，根据《工程数学》中的经典案例分析，电路中电压与电流在电阻恒定时也呈现直接成比例关系（欧姆定律）。此外，世界卫生组织（WHO）在公共卫生统计中常使用该术语描述变量间的关联性，如特定疾病发病率与暴露因素的量化关系。
"Directly proportional"（正比例关系）是数学和科学中描述两个变量之间线性关系的术语，具体含义如下：
核心定义
当两个变量满足"directly proportional"时，意味着它们的比值保持恒定。即一个变量增大，另一个变量按固定倍数同步增大，反之亦然。数学表达式为：
$$
y = kx
$$
其中$k$是比例常数（constant of proportionality）。
