我们要千方百计提高单位面积产量。
威尔格是一个土地面积单位。
它应该等于压强，或者说是单位面积上的受力。
一个平面物体的密度是每单位面积元的质量。
The density for a flat object would be the mass per unit area.
所以我们的到的是单位面积上的质量。
换句话说，这就是单位面积上的受力。
那意味着每单位面积的产量增加了超过6%。
That means the production increases more than 6 percent per unit of area.
这就等于一个单位圆的面积。
我同意，请问你要求的单位面积有多大呢？
比如，帕斯卡是用来测量某处面积所受压力的单位。
PASCALS, for example, measure the pressure applied to a certain area.
压力和力气不一样，压力是指单位面积内所承受的力。
Pressure is different from force — pressure takes into account the area over which a force is exerted.
好，这单位面积有多大？
这两个量，l乘以ρ,一起给出单位面积上的质量。
So these two together, l times rho, give us mass per unit area.
那么积分1dxdy的值,就是单位圆的面积π
Then the integral of one dxdy will just be the area of this unit disk which is pi.
库仑是测量静电电荷的单位（如果前述面积是一块合成纤维地毯的话，这种情况就有可能发生。）
COULOMBS measure electric charge (that can occur if said area is a synthetic carpet)
在面积这样小的区域内建造如此多的公寓单位，其住房密度将达到每英亩水域30个公寓单位，这样，该大楼周围便可留有更多的开阔水面。
With so many units built into such a small area, the housing complex will achieve a density of 30 units per acre of water, leaving more open water surrounding the structure.
比如探究气泡生长速率如何随气泡面的数目变化而变化，以及单位容量内使表面积最小化。
Those include uncovering how bubble growth rates vary with the number of bubble sides and minimizing the surface area per unit volume.
雨棚是根据相对于墙体面积的叶面积指数(LAI)来测量的；每单位LAI，日照减少约一半。
Canopy is measured according to leaf-area-index (LAI) relative to wall area; for each unit of LAI, sunlight decreases by about half.
那只意味着质量单位变成了面积单位。
新的更大的市政厅将会更加节能，单位面积所需的采暖和制冷费用都比旧建筑少。
The new, larger building would be more energy efficient, costing less per square foot to heat and cool than the old hall.
另外一个理解方法是，散度是源头的“冒出率”，它是流体往系统输入的量，也就是单位时间内，单位面积新冒出的流体。
The other way to think about it is divergence is the source rate, it is the amount of fluid that is being inserted into the system, that is being pumped into the system per unit time per unit area.
它增加了每一单位面积上厕所间的使用率。
敌人单位在效果的面积中暂时被使不动。
Enemy units in the area of effect are temporarily immobilized.
衡量农业技术的经济效果的基本指标，应该是单位面积的纯收入。
The basic criterion of measuring the economic effects is the net income per unit area.
他们研究了半个世纪以来世界上所有的渔场，其研究方法并不是为了试图估算特定区域的海洋中实际生物总数（活着生物的总数），而是研究单位面积中海洋生物数量发生的变化。
Their methods de not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time.
