If the path corresponds to a file, this function checks whether file size equals 0.
如果路径与文件对应，此函数将检查文件的大小是否等于0。
Suppose we were to graph a household's consumer spending as a function of cash-on-hand, which equals current income plus liquid assets, holding constant expected future income.
假设未来预期收入保持不变，画一个以家庭消费与库存现金的函数图---库存现金等于目前的收入加上流动资产。
The first section shows that the solution is optimal and that the objective function equals approximately 172667.
第一部分显示解是最佳的，目标函数约等于172667。
But now it looks like some function of x,y, z equals zero.
但是现在它看起来像x，，y，，z，的函数等于，0。
The objective function is named z and equals 3x1 + 2x2. Note that
目标函数称为z，它等于3x1 +2x2。
It says that the function must be used in an expression involving the comparison operation and that the search method "equals" of the index extension hash_index is referred to.
这说明，该函数必须在一个涉及比较操作并且引用了索引扩展hash _ index的搜索方法“equals”的表达式中使用。
So, just to get you used to this idea, I'm going to draw a level surface of a function of three variables OK, so it's a surface given by the equation w of x, y, z equals some constant c.
为了令你们习惯于这个想法，我画一个三变量函数的等值面,这是一个平面,由函数w=c给出的。
And the use of the filter function on the Array type to apply the "greater-than," "equals," and "less-than" functions to each element therein.
可以对Array类型使用filter函数，从而对其中的每个元素应用“greater - than”、“equals”和“less -than”函数。
Depending on your class, you may also want to delegate part of the computation to the equals() or hashCode() function of the superclass.
根据您使用的类，您可能希望降低superclass的equals()或hashCode()功能一部分计算能力。
Scala regards a method with the equals sign before the body as a function definition and a function always returns a value in functional programming.
Scala把主体之前的部分包含等于号作为函数定义，而一个函数在函数式编程中永远都有返回值。
The strain energy density function equals the helmholtz.
应变能密度函数等于亥姆霍兹函数。
Because semicolons, function return types, method arguments lists, and even the curly braces are sometimes omitted, using an equals sign prevents several possible parsing ambiguities.
因为分号，函数返回类型，方法参数列表，甚至大括号都经常会被省略，使用等于号可以避免几种可能的二义性。使用等于号也提醒了我们，即使是函数，在Scala里面也是值。
In this paper I get the profit be maximum, as the revenue function, cost function are continuous differential and the margin revenue equals margin cost, that marginal profit equals zero.
当收入函数、成本函数为连续可微函数，边际收入等于边际成本，即边际利润等于零时，利润最大；但在离散情况下，上述结论不一定成立，并给出反例。
