In July the temperature distribution shows considerable uniformity; the gradients are relatively weak.
The steep poleward pressure gradients of these southern oceans end in a trough of low pressure, girdling the earth at about the Antarctic circle.
All the roads over the downs are hilly ones; they are for ever either ascending or descending; their gradients are generally fairly severe, and their surfaces none of the best.
Fortunately I knew my car, my old and well-tried travelling companion that, when traversing some of the wild Welsh mountain and moorland tracks, had surmounted gradients of no ordinary severity.
Throughout South Africa the lines of railway are laid on steeper gradients than is usual in Europe: one in forty is not uncommon, and on the Natal line it is sometimes one in thirty, though this is being gradually reduced.
The gradients all through the interior plateau are comparatively easy, and the engineers have in Africa cared less for making their ascents gentle than we do in older countries.
I fear that might get us into trouble: You know there are such things as gradients and sections to be prepared.
Tremendous gradients lead through tunnels and over bridges, and the swerving carriages run often in alarming proximity to the edge of precipitous ravines.
Long steepgradients not only necessitate increased motive-power for the ascending trains, but also require increased brake-power, and precautionary measures for the descending trains.
On the other hand, in a river tunnel the gradients generally fall away from the entrances down towards the centre of the river, and all water coming in must be pumped out and raised up to at least the level of the river.
With stations on a summit, having gradients falling in each direction, the starting trains can get away more readily, and the arriving trains have the benefit of the rising gradient to assist them in coming to a stand.
The chief endeavour will be to gain length, and so reduce as much as possible the steepness of the gradients which at the best must necessarily be severe.
To facilitate drainage, it is essential that a railway tunnel should be laid down with a gradient or gradients falling in the direction of one or both ends of the tunnel.
When selecting a site for a station, not only should due regard be paid to the proximity and convenience of access to the town or place to be served, but attention should be given to the gradients of the line near the proposed station.
The gradients in a tunnel should be moderate, and not by any means excessive, or likely to tax the hauling powers of the locomotives.
The flexible girder system so reduces the "sag" that the maximum economy and durability are obtained, and the gradients over which the load has to travel can be made as easy and regular as those upon an ordinary railway.
Though in certain of the sections far to the east great engineering difficulties had to be contended with, the gradients on the greater part of the route are remarkably easy.
The gradients on the railways rising up to the viaducts are 1 in 135.
Other delays occurred because, owing to the heavy gradients of the Semmering Pass, each train had to be divided into three sections before it could proceed.
On the steep gradients there are switches which lead off from the main line and run up the mountain-side, so that a train rushing down the slope and running up on to one of these tracks soon loses its impetus and slows down.
The engineers, for example, do not impose on themselves the difficult and expensive condition of excluding all curves but those of large radius, and all gradients exceeding a certain small limit of steepness.
The largest ship can anchor close to shore, for the rugged boundaries of Banda descend by steep gradients into the crystalline depths.
From the blue Preanger hills and palm-shadowed upland plains, the railway descends by steep gradients to the dense jungle and fever-laden swamp known as the Terra Ingrata.
Even the railway has a most charming ramble, hunting its own tail up and down the long, steep, corkscrewgradients of the inland valleys.
It is getting along capitally, thank you, and tackles the steep ascent in a most business-like system of curves and gradients without bestowing a thought upon the lamentable hiatus in the rear.
Then by easier gradients than the path by which they had so precipitately descended, Louis struck diagonally for the old drove road.
It was a sharp angle of road, designed in days when levels and gradients were unthought of, and still permitted to linger on to the danger of travellers' necks.
After this there was a general stampede down and along the gradients of the Amphitheatre, during which hundreds of persons--including women and children--were crushed to death.
Men climbed down along the gradients leaping over other men, determined to jump down twelve feet into the arena in order to rescue the praefect from the jaws of the ferocious beast.
Then the praefect gathered my lord Hortensius' inanimate body in his arms as a mother would her own child, and with slow and steady steps he descended the gradients of the rostrum.
The region is an ancient peneplain, uplifted and dissected in late Tertiary times, with mature valleys whose gentle gradients are unbroken by waterfalls and rapids.
The line at this point is some 900 feet above sea-level, but although there are steep gradients the main altitude for a considerable distance varies little.
The frequent short gradients led to the most awful bumps and tearings at the couplings, but they stood the strain all right.
On the north and east the drop was almost precipitous, and it was really a wonderful engineering feat to get a railway down it at all--only accomplished by means of unusually steep gradients and sharp curves.
Pg413] From this table it is apparent that the gradients do possess the compensating power with respect to speed already mentioned.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "gradients" in a variety of sentences. We hope that you will now be able to make sentences using this word.
