In the temperature sensing, the theory of fiber Bragg grating temperature sensing has first been proposed, the characteristic of the FBG temperature sensing was analyzed, it was deduced that the sensitivity coefficients of first-order and second-order ,and experimental findings was protracted, the gained polynomial better inosculate with the theory value. The experiment was processed in the low temperature , the thermo-optic coefficient was emended in the polynomial of the normal temperature ,the result was accorded with the sensing character of the normal and low temperature ,and it was resolved that the theory account of the normal and low temperature did not accord with the experiment.

在温度传感方面，主要从光纤布拉格光栅的温度传感模式出发，对光纤布拉格光栅的温度传感特性进行了分析，推导出了光纤光栅的一阶与二阶温度灵敏度系数，并对实验数据进行了拟和，所得多项式和理论值吻合的很好，并对低温传感进行了实验，将在常温下得出的多项式进行了热光系数的修正，所得的结果同时符合常温与低温的传感特性，解决了低温与常温情况下的理论计算与实验的不一致性。

分析了原反应挤出实验的不足之处，通过增加解剖挤出机和错误实验，使实验教学不仅仅停留在简单的材料加工上，而且使学生对挤出机的结构、工作原理、工艺以及聚合物的改性有更深刻的理解，从而提高了学生的动手能力，创新能力和解决问题能力。

At the same time, the resonant frequencies of four kinds of resonator are calculated by the programs which are made with Matlab software. The effect of resonator geometrical parameters on resonant frequency is theoretically analyzed. In order to carry out the acoustic and aerodynamics performances tests, seven resonators are designed and made, and a specialized engine intake silencer and exhaust silencers test bench was designed. The tests and analysis are performed as well.

在此基础上设计并加工了两类七个共振型进气消声器，研制了发动机进排气消声器性能测试实验台，开发了发动机进排气消声器声学性能测试软件，并在该实验台上测试了所设计的进气消声器静态工况下的传声损失，从实验的角度研究了共振腔的尺寸、形状对其共振频率的影响及其趋势。

The statistic results show that the cost of experiments doubled every ten years because the price of the laboratory apparatus and the cost of labor force increase. On the other hand, the cost of computer simulation decreases due to the improvements of the computer hardware and software technology. Thus more and more researchers focus their interests on the technology of computer simulation.

近年来随着实验仪器、劳动力成本的增加，人们做实验的花费也随之成倍增长，据估计每过十年实验的成本就要翻一番，另一方面，采用计算机来模拟实际体系的成本却随着计算机硬件和软件技术的进步而不断下降，因此分子模拟技术越来越受到相关领域研究人员的关注。

Arthur Leonard Schawlow, for some time a professor at Stanford University but now deceased, showed theoretically that masers could be made to operate in the optical and infrared region and proposed how this could be accomplished in particular systems.

这个实验的精度是前无先例的，能测出小到10^-12的相对频率偏差，这更确凿地证实了七十多年前迈克耳孙-莫雷的实验结果，这个实验以及当时发现不久的穆斯堡尔效应，都证实了爱因斯坦的相对论理论。

This paper is derived from the experiment of the Reconnaissance and Jamming for Ultrashort Frequency Hopping Communication.

本课题来源于《超短波跳频通信的侦察与干扰实验》，该实验的目的是为了以实验的形式展示跳频通信的工作原理，跳频通信的侦察与干扰方法以及跳频通信各种干扰方法的性能比较。

Researchers at Johns Hopkins found that years after taking the hallucinogenic drug psilocybin in an experiment, subjects were still affected by their experience, during which they felt a profound connection to everyone and everything. Sixty-one percent felt that they were better people---more loving open, and sensitive.

Johns Hopkins大学的研究人员发现，在实验中服用迷幻药Psilocybin数年后，受试者依然可以感受到实验的经历对他们的影响，在实验中他们感受到自己与任何人和任何事间的紧密联系。61%的受试者感到他们的人格变得更好---更有爱心，心胸豁达和感受更加细腻。
