Unlocking the Climate Puzzle解开气候之谜(1)Life has prospered on this planet for nearly four billion years. In that time, climate had fluctuated drastically, from ice ages lasting tens of thousands of years to epochs of steamy heat. With each change, sundry species have benefited and flourished.Others adapted, faltered, or died. Now, many experts believe, humans are imperiling their own ecological niche with the threat of global warming. The vaporous by—products of civilization, in the form of greenhouse gases such as carbon dioxide (C0₂), have trapped enough heat in the atmosphere to raise Earth's average surface air temperature a half degree Celsius (one degree Fahrenheit) during this century. If the trend continues, it could alter climate patterns worldwide-thawing glaciers, boosting sea level, scorching plains into deserts, and shifting vegetation zones。

Atomic clocks in space could detect gravitational wavesClocks in space: narrowband gravitational-wave detector could take off. A proposal for a gravitational-wave detector made of two space-based atomic clocks has been unveiled by physicists in the US. The scheme involves placing two atomic clocks in different locations around the Sun and using them to measure tiny shifts in the frequency of a laser beam shone from one clock to the other.

UNIT 10 The first stage in the production of sand castings must be the design and manufacture of a suitable pattern. Casting patterns are generally made from hard wood and the pattern has to be made larger than the finished casting size to allow for the shrinkage that takes place during solidification and cooling. The extent of this shrinkage varies with the type of metal or the alloys to be cast. For all but the simplest shapes the pattern will be made in two or more pieces to facilitate moulding.UNIT 11 Grinding is one of the most widely used methods of finish machining parts to extremely close tolerances and fine surface finishes. Currently, there are grinders for almost every type of grinding operation. Particular design features of a part dictate to a large degree the type of grinding machine required. When processing costs are excessive, parts redesigned to utilize a less expensive, higher output grinding method may be well worthwhile.UNIT 12 A drill jig is a device for ensuring that a hole to be drilled, tapped, or reamed in a work-piece will be machined in the proper place. Thus instead of laying out the position of each hole on each work-piece with the aid of a square, straightedge, scriber, and center punch, the operator uses a jig to guide the drill into the proper place. Basically it consists of a clamping device to hold the part in position under hardened-steel bushings through which the drill passes duringthe drilling operation. The drill is guided by the bushings.UINT 13 The principle of cathodic deposition, as it is called, has many industrial applications. For instance, it is employed in the production of pure metals, such as aluminum or sodium, by using a fused ore of the metal as the electrolyte. Another application is in the process known as electroplating, in which a thin surface of some metal such as chromium or tin is deposited on a metallic base so that it adheres firmly to the base. Electro-forming, as distinct from electro-plating, involves growing metal on to a base in such a way that the base can subsequently be melted out or removed, leaving only the electro-formed deposit.UNIT 14 The common machining processes of drilling, turning, and milling generally produce a fairly large chip in comparison to grinding. Abrasive materials are the cutting tools in the machining process called grinding. Grinding machines and grinding processes make up one of the most important areas in all machining, grinding processes are most often used as finish machining processes. The reason for this is that very small amount of material can be removed from the work-piece. This is extremely useful in finish machining a part to close dimensional accuracy. Furthermore, grinding processes result in very smooth surface finishes on the work-piece.。
