Summary This paper analyzes the working principle and stability of a transistor mul- tivibrator operating as a frequency divider,with both sides being synchronized by the input signal.It is found that the frequency division stability of this circuit can further be increased when the multivibrator operates in the second class of oscillating condition,and that the optimum operating point is best determined from the actual base voltage changing characteristic.

本文分析了晶体管自激多谐振荡器用作双侧同步分频电路的一般理论和分频稳定性，并考虑基极电压变化规律来确定最佳分频的工作状态和运用点，同时对同步脉冲的引入问题亦作了原理性补充，还提出了振荡于第二类状态下的自激多谐振荡器可获得高稳定性的分频，以及此类双侧同步分频电路的设计方法。

"Decades after the hazards of smoking first gained national attention, tobacco use remains the leading preventable cause of illness and death in our society," said Rear Admiral Steven K.

"几十年后，吸烟的害处首先获得国家的重视，烟草使用的仍然是领先的可预防的原因的疾病和死亡在我们社会里，说："海军少将史蒂芬k。

The use of the Chinese remainder theorem transforms the operation of producing the multiplicative inverses into two corresponding operations with shorter numbers and a faster combination step so that, compared with methods not using the Chinese remainder theorem, an acceleration by factor 4 can be achieved.

采用中国余数定理，形成将倍数逆数的运算转换为两个具有较短数字和一个较快结合的运算的步骤，使得相较于没有中国余数定理的方法可获得因子4的加速。

①本课题所用的技术和获得的数据可被用于进一步研究患者的异常的肩胛带运动的病理性改变，有利于为肩部疾患的手术干预和非手术治疗提供基础的生物力学资料。

The indentation loading curve with a spherical diamond tip was employed to determine the yield strengths and hardening indices of Cu films which were prepared on silicon substrates by different ways with the same thickness of 1. 5μm. The result showed that the yield strength of the Cu film depends on the deposition technology, and is much higher than that of the bulk material.

结果表明，在薄膜厚度相同的条件下，铜膜的屈服强度与铜膜的制备方法有关，选择IBED法较MS法可获得更高的屈服强度〓此外，由两种方法所镀制铜膜的屈服强度均远高于其体材，这与铝膜的情况相一致，说明薄膜与整体材料在强度方面存在显著差异的结论具有普遍性。

The effect of additives on synthesis of xonotlite fiber with nano diameter is studied using industrial lime and quartz powder,selecting calcium chloride,strontium nitrate,zirconium oxychloride as additives.

采用工业石灰和石英粉，选用氯化钙、硝酸锶、氧氯化锆为添加剂，研究添加剂对合成纳米直径硬硅钙石纤维的影响，结果表明，几种添加剂均对生成硬硅钙石纤维有一定的帮助，加入适量的氧氯化锆添加剂，可以制备出纳米直径的硬硅钙石纤维，氧氯化锆的添加量为Zr4+/(Ca2++Si4+)=0.02时，可获得结晶良好、直径为70～100 nm的硬硅钙石纤维。

This paper discusses the research carried out on the Lake Sugan, in the northern margin of Chaidam Basin. The climate and environmental changes in Lake Sugan drainage area over the past 2670 years were studied using the varve dating of the well preserved lamination sediments in core SG03I taken from the center of Lake Sugan, the study of varve formation in modern lake system and modern process study of carbonate and oxygen isotopes of the water within the drainage area, and according to the main index of the stable isotopes of carbonate sediments synthesized other index analysis.

本文以柴达木盆地北缘苏干湖为研究对象，通过对湖泊中心位置SG03I孔保存完好的纹泥沉积物岩芯进行年代学研究，对湖泊现代沉积过程及碳酸盐、流域水体同位素进行现代过程研究，以沉积碳酸盐稳定同位素指标为主，结合其它代用指标的综合分析，探讨苏干湖流域近2670年来的气候与环境变化，综合区域其它记录对苏干湖流域晚全新世气候变化的驱动机制进行探讨，获得如下认识：1、柴达木盆地北缘苏干湖若干钻孔岩芯发现，水深大于3.0m的沉积物均具有裸眼可分辩的由深色层和浅色层组成的纹层层理。
