建立人输卵管上皮细胞无血清培养

人输卵管上皮细胞（HOEC）可以体外较长时间无血清培养,DMEM／F12培养液的培养效果优于Ham’sF10,在加有多种因子和胎球蛋白的培养液中,HOEC可贴壁生长,生长能力达到合质量分数15％FCS的对照组的30％～40％,一般可传代2次,最长培养可维持38d,细胞形态与有血清培养差别不大,虽然无血清培养HOEC的生长速度、密度、传代成功率远不及有血清培养,但能抑制成纤维细胞生长,维持较纯的上皮细胞。

Relationship between the partitioning properties of motoneuron recruitment and the needle feeling propagation

Histological and physiological studies indicated that most skeletal muscles can be divided into a series of relatively independent sub-volumes: "neuromuscular compartments" and the partitioning property of the muscle result in the localization of muscle reflex. In the present experiment we studied the recruitment properties of medial gastracnemius (MG) muscle motoneuron pool of decerebrate cat with two kinds of local mechanical stimulation: local stretch and acupuncture-like stimuli. The results indicate that: (ⅰ) there is an obvious property of localization of recruitment activity, only the MNs which innervate the stimulated compartment were recruited by weaker and shorter stimuli; (ⅱ) recruitment activity spread to those MNs which supply the adjacent and distal compartments during the strength of stimulation or duration of the stimulation was increased; and (ⅲ) the recruitment property of muscle activity elicited by the local mechanical stimulation is thought similar to that of "needle feeling" along the meridian pathway during stimulation of acupuncture point.     

Determination of tectonic background for sedimentary basin from sandstone geochemistry

The chemical composition of sedimentary rocks is mainly controlled by source rocks. Through examining chemical composition of terrigenous rocks, the tectonic evolution of a sedimentary basin can be modeled. The Turpan Basin belongs to a continental sedimentary basin and its source rocks are derived from the upper continental crust.     

Chronology of environmental events over East Asia during the past 130 ka

In the transitional region between the Loess Plateau and deserts, 4 sections located respectively at Yuling, Hengshan, Dingbian and Huining of China are studied. The high-resolution paleoclimatic records obtained show that environmental events on varying time scales have happened over East Asia. These events are dated with the time scales established using the recently-developed approach of Automatic Orbital Tuning. This leads to the establishment of the chronology of the environmental events.     

An all solid-state electrochromic smart window

An all solid-state electrochromic smart window employing prussian blue and electrodeposited WO₃ film with poly (vinyl chloride) (PVC) gel electrolyte that has high conductivity (2 mS/cm) at room temperature has been fabricated for the first time. The smart window has beell found to be excellent for electrochromism and memory characteristics.     

多晶3C-SiC薄层的淀积生长及结构性能分析

采用ＨＦＣＶＤ生长法,以较低生长温度,在Ｓｉ（１１１）衬底上淀积３Ｃ－ＳｉＣ（１１１）薄层。用ＸＲＤ、ＶＡＳＥ、ＸＰＳ等分析手段研究了薄层的结构、光学常数、组分及化学键等性能。ＸＲＤ显示薄层具有明显的择优取向特征。ＶＡＳＥ测量出薄层的折射率为２．６８６,光学常数随深度的变化曲线反映出薄层的多层结构。ＸＰＳ深度剖面曲线表明薄层中Ｓｉ／Ｃ原子比符合ＳｉＣ的理想化学计量比,其能谱证明Ｃ１ｓ与Ｓｉ２ｐ成键形成具有闪锌矿结构的３Ｃ－ＳｉＣ。
