The Work Group urges program directors, faculty, and residents to recognize the signs of sleep deprivation and to relieve residents from duty when fatigue may hinder patient care or learning.

工作小组极力主张计画主持人、全职人员和住院医生能识别睡眠剥夺的症候，并且当住院医师疲劳程度达到阻碍其对患者的治疗或学习时，能将他们从工作中解放出来。

Because groundwork adopting ferroconcrete structure is chosen in advance, drive error of theodolite working on it is very little and can be ignored.

由于地基是事先选好的，多采取钢筋混凝土结构，经纬仪借助于地基环固定在地面上，工作时带动误差非常小，可忽略不计。

Using this kind of fluxmeter, the heat-flux distribution in a pulverized-coal tangentially-fired test furnace under different operating conditions, the effect of sandwiched-air on the heat-flux and the dependence of the distribution on the coal properties were measured and investigated.

利用该辐射式热流计，作者测试并研究了四角布置切向燃烧锅炉炉膛内在不同燃烧工况下的辐射热负荷分布规律、夹心风的投入与关闭对炉内热负荷分布的影响，以及煤种变化时炉内热负荷分布的变化。

By the 1800s American manufacturers were turning out millions of be frilled valentines.

因此以商业为目的的情人卡使出现了，到19世纪时，美国的制造商们生产了数以百万计的饰有花边的情人卡。

In comparison with the scheme of high-order SQUID gradiometer, the method is simple without introducing any extra-intrinsic noise to SQUID sensor.

与高阶梯度计方案相比，虽然当环境干扰改变时，它保持平衡的能力较低，但是这种方法不仅简单易行，而且对SQUID不引入任何附加的本征噪声，从而可大大降低建造昂贵电磁屏蔽室的费用。

Those MEp that occurred as subsolid mineral with or without resorption of earlierformed hornblende, can be use as pressure indicator for intrusion.

而晚期近固相线晶出的绿帘石时，能够作为压力计反映岩体最小侵位深度。据此可以应用于对地壳演化和隆升的研究。

MEp which crystallized earlier than biotite or hornblende in the magma, can not be used as a barometer, but be useful in caculating the ascent speed of magma.

作为早期结晶的矿物，绿帘石不能作为压力计来反映岩体侵位深度，因为在绿帘石晶出时，岩浆中液相体积在50%～80%，这样岩浆可能会有快速侵位的过程，但它的地质意义在于能够对岩浆上升速率做出估算。

The residual gas pressure in an electron tube can be measured when the tube itself is operated as a hot cathode ionization gauge.Usually,its sensitivity K is determined by the method of gauge calibration.In this paper,author try to determine the sensitivity K by ca- lculation.The formulae for this purpose have be found out,and are used for both plate and cylindrical electrode systems.

把电子管接成热阴极电离计的工作形式，用来测量管内残气压强时，其灵敏度如何计算的问题在本文中作了讨论，给出了平板形电极系统和圆柱形电极系统的灵敏度解析式，对式中各量的计算作了详细介绍；并指出四极管中电子在电离区的平均渡越次数的表示式与三极管中的完全不同。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
