| Design of all the new tools and
implements is based on careful experiments with electronic instruments. First, a
human "guinea pig" is tested using a regular tool. Measurements are taken of the
amount Of work done, and the buildup of heat in the body. Twisted joints and
stretched muscles can not perform as well, it has been found, as joints and
muscles in their normal positions. The same person is then tested again, using a
tool designed according to the suggestions made by Dr. Tichauer. All these tests
have shown the great improvement of the new designs over the old. One of the electronic instruments used by Dr. Tichauer, the myograph (肌动记器), makes visible through electrical signals the work done by human muscle. Another machine measures any dangerous features of tools, thus proving information upon which to base a new des A. they are twisted and stretched B. they are in their normal positions C. they are tested with a human "guinea pig" D. they are tested with electronic instruments [填空题]
What does the new emergency base on [单项选择]It is said that mathematics is the base of all other sciences, and that arithmetic, the science of numbers, is the base of mathematics. Numbers consist of whole numbers which are formed by the digits 0,1,2,3,4,5,6,7,8 and 9, and by combinations of them. Parts of numbers smaller than 1 are sometimes expressed in terms of fractions (分数), but in scientific usage they are given as decimals (十进位). This is because it is easier to perform the various mathematical operation if decimals are used instead of fractions.
The decimal, or ten-scale, system is used for scientific purposes throughout the world. It is even accepted in countries whose national systems of weights and measurements are based upon other scales. The other scale in general use nowadays is the binary, or two-scale. In such a scale, numbers are expressed by combinations of only two digits, 0 and 1. This scale is perfectly adapted to the "off-on" pulses of electricity, and so it is widely used in computers. It is because of [单项选择]
