The author found that the big piece-size muscovites of China are the normal muscovites; the small-size muscovites in the metamorphic rock area are mainly phengite. The Indian muscovites studied both big and small piece-size of muscovite, are normal muscovites. The surface activity of Indian muscovite substrate is higher than China ones. Acid is easy to erode paralleling to the direction of the muscovite substrate face. Although acid treating does not destroy the muscovite structure, the thermal stability of muscovite has be decreased.
研究发现我国白云母主要产地的大片白云母均为普通白云母,变质岩地区的碎白云母以多硅白云母为主;本文研究的印度的大片白云母、碎白云母均为普通白云母;印度白云母基片的表面活性高于我国白云母;酸处理容易沿平行于白云母基面的方向侵蚀,虽未使白云母晶体结构产生破坏,但造成了白云母热稳定性降低。

Qualitative and quantitative analysis of chemical constituents.(1) Based on the GC spectrum of 2 species, Whitmania pigra and Poecilobdella manillensis shows little difference between them. 24 kinds of fatty acid in Whitmania pigra was firstly separated and determined by GC/MS. Among them, phenylacetic acid is a component which has active of anticancer. The existence of many unsaturated fatty acid provides chemical evidence for ShuiZhi's functions of invigorate the circulation of blood.
六首次对两种水蛭的脂肪酸类化合物进行了GC定性分析,发现其脂肪酸组成未见明显差异,后又对宽体金线蛭的脂肪酸类化合物进行了GC-MS分析,初步鉴定出24个化合物,包括苯乙酸、龙脑和22种脂肪酸,其中所含的苯乙酸具有抗肿瘤活性,大量不饱和脂肪酸的存在为水蛭在血液流变学方面的药理作用提供了一定的化学依据。

Compared to the sample without ultrasonic treatment, it was found that, for AZ31 magnesium melt alloy treated by ultrasonic, the refined grain size and the inproved distribution of grain with its shape of oval-shaped or spherical can be obtained, and the precipitation inside Al matrix was inhibited The Mg17 Al12 precipitates distributed mainly along the grain boundary and hardness was improved remarkedly.
通过对铁合金AZ31进行熔体超声处理发现,处理后试样的晶粒较未进行超声处理的试样有明显细化,分布均匀程度提高,形状呈椭圆状或球状,合金元素Al在晶粒内的析出被抑制,Mg17Al12第二相的析出主要集中于晶界,硬度有明显提高,并且通过试验确定出了最佳处理功率和时间,为超声波在铸造生产中的应用提供了依据。

The function of 3dB fiber loop mirror in fine wavelength partition is studied. With this theory, a novel narrow linear band, dual-wavelength switchable Er-doped fiber laser is realized.2. An unpumped Er-doped fiber and broadband fiber Bragg grating with high reflectivity is served as an auto-tracking filter, where the space hole-burning effect appears when the laser signal travels and forms standing wave, thus the generation of multi-longitudinal-mode is suppressed. Then the high birefringence fiber loop mirror is introduced to act as comb-liked wavelength filter.

DSC results show that crystallinity of the geogrids ribs is different owing to various stretching technical factors, and that the crystallinity of the stretched sample is larger than the unstretched one. The crystallinities of the sample are similar at lower draw temperature and higher draw speed, which show that there is correlation among the stretching factors.
通过对试样肋条部位结构的DSC分析,发现拉伸工艺参数不同,肋条部位的结晶度不同,且拉伸后试样的结晶度均比未拉伸时有所提高;较低拉伸温度下与较高拉伸速率下试样的结晶度相近,表明各拉伸参数之间具有一定的关联性。

The frequency value in S phase is 4. 83 times of M phase, 2. 9 times of G1 phase, and 3. 41 times of unsynchronized cells. These results suggested that gene correction events were highly related to S phase. Then we compared the targeting efficacy for two groups of cells in S phase. One group was contact with thymidine and the other one went smoothly through S phase without replication blockage.
基于这种原因,我们对基因定点修复事件做了细胞周期定位分析,发现同步于S期的细胞群发生定点修复的效率明显高于其它各期以及非同步化的细胞,流式细胞仪检测S期定点修复效率为M期细胞的4.83倍,为G1期细胞的2.9倍,是未同步化细胞的3.41倍。
