Methods 50 non-organic cardiopathy patients who have ventricular premature beat are compared with 100 healthy persons in heart rate variation.(24 hours' long duration).

方法对 5 0例无明显器质性心脏病室性早搏患者及 10 0例健康人做 2 4h长程心率变异比较，分析NOCP室性早搏的HRV的变化。

Figure 11.4 lists the sizes of 0.5 LSB at various resolutions (the values are given for 10 V fullscale since this is a classical converter range and where LSBs are given a mV value in this section of the seminar a 10 V FS is assumed unless explicitly stated otherwise - scaling to other values of FS is a trivial operation).

图11.4给出了不同分辨率条件下0.5LSB对应的变化量。（鉴于目前模数转换器典型的满量程范围是10V，所以表格中的数据都是按照满量程10V计算。本文中，如果没有特别说明，当1LSB为mV量级时，其满量程范围都是10V，满量程不等于10V的情况可以参照本例推算。

Results The hair-cell-like cells with tufts of microvilli were found on their surface in the damaged organ of Corti at 7 days after stopping of injection.

结果 在外毛细胞损伤区有细胞表面长有微绒毛簇的毛细胞样细胞出现，且其在损伤Croti器中有发生-发展-退化的变化过程。

In this disclosure, the computations and analyses of stress and displacement fields of drum and conveyor are carried out by a finite element analysis software, ANSYS. And by changing the parameter value of drum and conveyor, influences of parameters on the strength and displacement are investigated.

本论文应用ANSYS有限元分析软件对大型卧螺离心机的转鼓和螺旋输送器进行了应力场和位移场的计算与分析，并调整它们的各项参数来研究参数的变化对它们的强度和变形的影响。

In order to understand the preheating process in this new injector, the temperature of diesel fuel preheating by PTC ceramics was recorded under different voltages, of which Curie point is 75℃.

为研究喷油器内PTC材料加热柴油的过程，试验选择了居里温度为75 ℃的陶瓷基PTC材料为加热元件，测量了不同电压下用PTC陶瓷加热柴油的温度变化规律。

Millikan, adding: It appeared that the surgery patients had a better long-term change in their left ventricular geometry than did the patients treated with the clip.

研究发现，外科治疗组患者的左心室功能图的长期变化好于夹合器治疗的患者。

Microscopic characteristics of cladded crystal fiber are analyzed by X-ray diffraction, Laue X-ray diffraction and scanning electron microscopy, it is found that magnesium-ion indiffusion does not affect the single crystal structure and the domain structure of the magnesium diffused crystal fiber. It is found for the first time that MgO-rich layer in the magnesium diffused LiNbO〓 surface layer exhibits the crystal structure of an unknown compound from the Li-Mg-Nb-O ternary system and MgNb〓O〓. It is proposed for the first time that this unknown compound and MgNb〓O〓 in MgO-rich layer are the real sources of magnesium-ion indiffusion LiNbO〓. Their appearance indicate that MgNb〓O〓 is in the surface layer of MgO-rich layer, the unknown compound is in the subsurface layer and beneath where the MgNb〓O〓 is located, and these compounds have obviously preferred orientation.

通过镁离子内扩散法，首次在国内实现了具有阶跃和抛物折射率分布的c轴LiNbO〓单晶光纤和a轴Nd：MgO：LiNbO〓单晶光纤的芯—包层波导结构，为我国在该项目的研究填补了空白；建立了晶纤损耗的测量系统，提出了利用单模石英光纤作为晶纤入射光耦合器的思想；通过对晶纤损耗的测量，得到了包层晶纤比未包层晶纤损耗降低约14倍的好结果，并实现了低次模传输：对经镁离子内扩散实现包层后的晶纤的微观特性，利用X射线衍射，劳厄照相和扫描电镜表征发现，晶纤并不因镁离子的内扩散而影响其单晶结构和镁的扩散层畴的变化。

We will see more and more activist government policies that distinguish economic activities according to the nationality of the actors.

我们将看到越来越多激进的政府政策，这些政策根据企业的国籍来区分经济活动。

If we can prove the independence of an axiomatic system, then we can guarantee the conciseness of this system, ie.

如果能够证明某个一阶谓词系统的独立性，那么就能够保证该系统的建立是精炼的，即没有任何一条公理或推理规则是多余的。
