Mechanical structure is the central body of the test machine.

机械结构是测试机的核心机构。

Just as the sun is the central body of the solar system, so the nucleus is the core of the atom...

正象太阳是太阳系的中心天体一样，原子核是原子的核心。

Result The alteration of central body temperature of experimental dogs was different in various ambient temperatures.

结果：不同环境温度下的实验犬中心体温变化不同。

The central body of the plane is made entirely of carbon composite material, which makes the plane lighter and more fuel efficient.

机身主体全部由碳合成材料制成，因此重量更轻，更加省油。

Conclusions the ambient temperature affected the central body temperature of experimental animals directly during their operation.

结论：环境温度直接影响实验动物术中中心体温。
