Through the multiple stepwise regression analysis, the duration of the disease and serum GH level were the main influencing factors of acromegalic cardiomyopathy. 2 Ejection fraction and fractional shortening, were decreased, compared to control group, they still remained in normal range. 3 Isovolumic relaxation time and E wave descending time, were delayed apparently compared to control group, indicating the damage of cardiac relaxation. 4 Subgroup analysis in acromegalic: The comparison between patients with diabetes mellitus and impaired glucose tolerance and patients without DM/IGT showed that there was no significant difference in terms of the parameters in the two groups, in spite of an mild increase of IVST in the former group.

经多元逐步回归分析，病程和血清生长激素浓度为心肌肥厚的主要影响因素。2实验组射血分数和左心室短轴缩短率虽较对照组低，但仍在正常范围。3实验组左心室等容舒张时间和二尖瓣减速时间较对照组明显延长。4实验组中继发糖尿病／糖耐量减低组与非DM/IGT组进行比较，前者仅室间隔有较明显增厚，其余各项参数2组间差异均无统计学意义。

The so-called "adiabatic expansion" means that the light generated by the acoustic signal in the absorption within the region transit time under the same conditions are far greater than the time required for thermal diffusion, negligible effect of the proliferation of light signal the impact of this Conditions, acoustic imaging to short-pulse laser for excitation, ultrasonic signal for the information to the carrier, with high-resolution and high-contrast imaging features.

所谓的"绝热膨胀"是指所产生的光声信号在吸收区域内的渡越时间远远大于相同条件下热扩散所需的时间，可忽略热扩散效应对光声信号产生的影响，在此条件下，光声成像以短脉冲激光为激励源、以超声信号为信息的载体，具备高分辨率和高对比度的成像特点。

高立柱 ，刘艳红，田秀云为缩短2024铝合金的自然时效时间，本文通过对2024铝合金导电率和硬度实验研究以及对它的时效机理的分析，初步确定了2024铝合金的一种新的时效时间较短的人工时效制度。

The application of PDT to the inpatients of GBS with respiratory muscle paralysis has advantage such as simple operation, short ventilating time and short hospitalization duration, low occurrence rate of ventilator related pneumonia, etc. It should be considered as the first- choice method to opening the air-way for the disease.

PDT用于急性GBS综合征致呼吸肌麻痹患者具有操作简单、通气时间、住院时间短、住院期间呼吸机相关性肺炎的发生率低等优点，应作为该病开放呼吸道的首选方法。

Compared to the conventional interleaving SLM, this short-span interleaving SLM results in a very short time delay, requires very few register units for buffering, and can be easily implemented by hardware.

与传统的基于交织的选择性映射方案相比较，这种基于短跨度交织的选择性映射方案产生非常短的时间延迟，只需要很少的缓冲寄存器，且易于用硬件实现。

For the variation of short period of astronomical factors, whether for local time or local sidereal time and lunar phase there is the phenomenon of occurrence of concentrating a interval time for the earthquakes. For the short variation of earth rotation this phenomenon is clear; either the earthquakes occur in most fast or in lowst of earth rotation.

对于天文因素的短周期变化，无论是对于地方时，地方恒星时与月相，都有集中发生在某一段时间的现象；对于地球自转的短周期变化更是比较明显，要么发生在其变化最快时期，要么发生在其变化的最慢时期。

This paper introduces the studies of the ultra-short Thomson scattering X-ray source at the accelerator laboratory of Tsinghua University in recent years. Properties such as the photon yield,the pulse length and time jitter of the produced photon pulse were predicted theoretically from the parameters of the electron bunch and the laser pulse,and the scattering angle. Preliminary experiments were successfully carried out with a 16 MeV backward-traveling-wave accelerator and the ns-Q switched laser provided by China Academy of Engineering Physics. This paper also introduces the 1.6-cell electron gun that was fabricated on site and the experiment with high RF power including the measurement of the electron bunche parameters. Based on these,we have designed an X-ray source,which is now under construction.
