Bieti lost its habitat continuously in recently decades associated with the extension of rangelands and farmlands, as well as firewood collection etc. The monkey live mainly in primary fir forest and the mixed conifer forest, to evaluate the status of the monkeys' habitat, we employed GIS and RS software to identify the habitat types with five Landsat TM/ETM+ satellite imagery in winter of 1986, 1992, 1997, 2001 and 2006 years respectively. The work resulted in: 1 the size of summer grazing lands, farmlands, and fir forest was 13 100 hm2, 6 400 hm2, and 30 500 hm2 in 2006 respectively; 2 during the past 20 years (1986-2006), the size of fir forest (including primary fir forest and the mixed conifer forest) decreased by 14.6%(5 200 hm2), summer grazing lands and farmlands increased by 47.2%(4 200 hm2) and 14.3％(800 hm2) respectively; and 3, during the past 20 years, the number of firry forest patches increased by 68.4%, the mean size of firry forest patches decreased by 49.3%(from 15.1 to7.6 hm2), the largest patch index of firry forest decreased 54.9%; the patch richness had no change, but the Shannon's diversity index and the Shannon's evenness index increased by 2.7% respectively.

XRD showed hexagonal wurtzite structure. Room-temperature PL spectra of perfectly overcoated CdSe/ZnS only showed a narrow band edge emission. Emission peak was great red-shifted relative to absorption and the shift increases as the size decreases. The size-dependence of shift could be explained very well in terms of excition fine-structure model and stress at interface owing to lattice mismatch contributes to the shift between CdSe and CdSe/ZnS with the same size.

结果显示表面修饰完善的样品的荧光光谱只有一个窄而强的带边发射；所有样品的荧光峰相对于1S-1S吸收峰有较大的红移，并且移动量随尺寸的减小而增加，利用激子的精细结构模型很好地解释了红移量和尺寸的关系；核／壳结构的样品的吸收峰和荧光峰相对于同尺寸的单量子点也有红移现象，这是由于CdSe和ZnS的晶格失配在界面上产生压力造成的。

A relative low lake level between 8660～6010 cal.yr BPwas reflected by the clayey silt sediment with the median size less than 25μam and the sandcontent less than 4%,and the Pediastrum concentration was normally low.Between 6010 and2250 cal.yr BP,the median size and sand content increased greatly,and the Pediastrumconcentration raised sharply,suggesting a relative low lake level.After 2250 cal.yr BP,boththe median size and the Pediastrum abundance abruptly declined,suggesting the lake returnedto high level and the climate changed to humid.

UG04孔硅藻记录重建的湖泊水位变化基本上支持孢粉重建的古植被和古气候：8660～7230 cal.yr BP硅藻组合以浮游类主导，浮游／底栖比达40以上，指示水位较高，气候略湿润；7230～2330 cal.yr BP浮游类硅藻丰度和浮游／底栖比降低，湖泊处于低水位，气候干旱；2330～930 cal.yr BP浮游类硅藻丰度和浮游／底栖比增加，湖泊水位升高，气候湿润。

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。

The results showed that spherical BaCO3 particles with low reaggregation and uniform size of about 100nm could be prepared by using solid-state reaction of Ba(NO3)2 and Na2CO3 at room temperature; while stick shape particles, whose size is not uniform, were obtained for the BaCl2 2H2O and Na2CO3 system.

As consequence of agglomeration, the particle size was much larger than 2μm though; when adding solution of 0.5% SLS to redisperse the solid systems, the particle could retain stable in size from 30mins to 90mins following drying and reach smaller size of 500nm~2μm in most experimental groups.
