We have studied the heat leaks and temperature profiles of a wide-necked glass liquid helium experamental dewar (60mm i.d., 700mm long). It is found that the-room-temperature radiation down the neck is a dominating factor. It determines the vertical temperature profiles in the 20-30cm range (60-280 K) from the top of the dewar and about 85-95% of the total heat flux into the liquid helium. The reflective coefficient of the wall is about 0.7. We have also studied the changes caused by the 77 K baffle and...

The frequency response of human ear measured for right and left ear of ten subjects under "unclosed seal" (or natural seal) and "closed seal" conditions is described, as well as equivalent electrical network is analysed. In the equivalent electrical network the acoustical mass of acoustic leaks is very important for impedance over the range from 250 to 1000Hz under the leakage conditions. The difference of the frequency response of human ear measured under closed seal conditions among different ethnic groups is very small after the comparisons are made. This work illustrates that only if the closed seal method with a standard high impedance earphone is used in measuring the real ear frequency response, the artificial ear used in audiometry can simulate these closed seal curves.

本文通过对十人双耳分别在松弛密封(或自然密封)和紧固密封条件下的人耳频响测量以及等效电路的推导和分析,说明声漏中声质量分量是不可忽视的;在250~1000赫频段内,声阻抗主要由它决定。在250赫以下声漏中声阻分量才起主要作用。本文对本实验频响与国外公布的人耳频响进行了对比,表明不同人种之间的平均人耳频响差别不大。采用高声阻抗标准耳机测量人耳频响时,证明只有紧固密封才能测出人耳实际频响,计量院测听仿真耳与IEC 318仿真耳一样,皆能较好地模拟紧固密封人耳频响。

In this paper we have make theoretical count for the partial pressure sensitivity in atomsphereusing using the sniff probe method in a helium msas spectrometer leak dctcctor and the theoretical analysis in under the leakage case of the simulation micro-leak on thc pressurized chamber in atomsphere. This leakage reveals sub-molecule flow state. The measurmenets show that when the sniff probe is equiped with a JLH-1 or HZJ-1 helium massspeetrometer Ieakddetector, its effetive dctectivity is 10~(-7) TL/sec if it is fit with a ZLS-23 helium mass spectrometer lcak dctector, its effective dctcctivity can be counted as 10~(-9) TL/sec. Simultancously the relation of rcmovd speed in detection to sensitivity is measured. In addition, the probability in using this method to detect largcr chamber is given.

本文对氦质谱检漏仪的嗅敏探枪法在大气中的分压灵敏度进行了理论计算并对加压容器上的模拟微小漏孔在大气中的泄漏情况进行了理论分析,实验证明呈准分子流状态。实测结果表明,当使用JLH—1或HZJ—1型氦质谱漏仪探测时,其有效最小可检漏率为10~(-7)托·升/秒;如果用ZLS—23型氦质谱检漏仪,可以算出其有效最小可检漏率为10~(-9)托·升/秒。同时还实测了移动式探测速度与灵敏度的关系。指出了上述方法检验大型容器的可能性。
