The structural deformation is the principal geological factor that affects the thickness variation of coal seam on a mine field scale.

The field scale spatial variability of soil properties is one of the key factors which have considerable effect on water flow and solute transport.

田块尺度土壤特性的空间变异性对水分与溶质运移具有明显的影响。

Due to great spatial variability of this hydraulic property, direct measurement seems to be infeasible and even impossible, especially for a field scale problem.

对于一个较大范围的实际问题，由于其在空间和时间上的强烈变异性，采用直接实验大量测定通常是不可行的。

Even with somebody who works in the field and understands scale, renderings and models, when they're finally next to their creation, in the form of a real Macy's balloon, it always takes their breath away.

As noted above, the use of genetic engineering techniques for anything that falls within the regulatory definition of a "pesticide"--even when that definition is tortured to claim jurisdiction--triggers case-by-case review, which is not necessary for small-scale field trials for other pesticides, regardless of risk.

This will be a really big deal if it works, and small-scale field tests seem promising. (The quality of the video below is lousy, but it gives you the idea.) The most intriguing thing about Square, though, at least so far, is the conceptual leap that Dorsey may have been uniquely qualified to make: Payment transactions are a kind of social interchange.
