There is a normal human body temperature range of more stable, it is hypothalamus through the brain and central regulation of body temperature regulation and the role of neurohumoral to heat and maintain the dynamic balance of heat, but it is not constant change.

孩子什么时间体温最高什么时间体温最低？人体正常体温有一个较稳定的范围，它通过大脑和丘脑下部的体温调节中枢调节和神经体液的作用，使产热和散热保持动态平衡，但并不是恒定不变的。

The special tribo-electdc tester with high sliding speed and electric current was developed,which mail working parameters are, current density up to 2.5 A/mm~2, the sliding speed 100 m/s,the load over 500 N (3.2 MPa) and the pulsant strike pressure within 20 N. This testersuccessfully simulates the tribological and electric properties of strip materials. 2, By using the above tester, study on tdbological properties and carrying currentperformances of copper-base powder metallurgy material and metal impregnation carbonmaterial are carded out.

According to the principle of mutual transformation between potential energy and kinetic energy,the vertically falling law of power law fluid by the action of unconstant static pressure and the relation between rheological parameter and time were studied,thus providing a theoretical basis for calculating the rheological parameters of fluid in funnel viscomete...

根据位能与动能的变化关系，作者研究了在非恒定静压作用下幂律流体垂直下落的规律及流变参数与时间的关系，从而为计算漏斗粘度计中流体的流变参数提供了理论依据。

The rate of wetting front advance and infiltration rate under certain ponded infiltration was significantly reduced by Sodium Polyacrylate , and as a result effectively reduced water in a sandy soil leaking to a deeper layer under the plough layer.

砂土的饱和导水率随着高分子化合物聚丙烯酸钠用量增加而降低，在恒定水头入渗条件下，聚丙烯酸钠降低了水分向深层运移的速度，同时降低了砂土的入渗速率，可以有效降低砂土水分的深层渗漏。

What's more, the begavior of the metals at excessively high temperature also differs from that at normal temperatures and can produce a condition in which the metal deforms slowly and continuously at a constant stress.

另外，在过高的温度下金属的反应也不同于正常温度，过高的温度会引起金属的缓慢变形和金属承受持续的恒定压力。

The constant form of this receptivity, which we term sensibility, is a necessary condition of all the relations in which objects can be intuited as outside us; and if we abstract from these objects, it is a pure intuition, and bears the name of space.

这种我们称之为感性的感受性的恒定形式，是对象在其中被直观为在我们之外的各种关系的一个必要条件，而如果人们抽掉这些对象，它就是一个拥有空间之名的纯直观。

This paper refines the design of former simulator which is investigated and fabricated by our team, makes it as the solar simulator, and finishes the hardware and software design of a solar cell string tester, adopting the high speed DAQ system which is controlled by a industrial computer and making MOSFET as the electronic load, testing electric performance of strings rapidly.
