The results show that the density of gritstone is decreased gradually as the temperature increasing; so that it can be ignored; the longitudinal wave velocity is linearly decreased when the temperature increasing, and decrease rate of it follows the law of conic; R is one temperature point, which makes the law of tensile strength of gritstone after high temperature follows the law of parabola; and the maximal tensile strength appears when the operative temperature is R. After the temperature is higher than 700 ℃, tensile strength is small and change range is small when the temperature is increased.

Pyronine B adheres to on the surface of CdS and prevents CdS aggregating, which leads to the decrease of fluorescence quantum yield of CdS. Fluorescence resonance energy transfer happens from CdS to Rhodamine B, Butyl rhodamine B and Rhodamine 6G, respectively. There is a higher FRET efficiency between CdS and Neutral red with the value being 0.282. Moreover, coupling reaction between -NH_2 of Neutral red and -COOH of CdS -TGA leads to red shift of CdS fluorescence spectrum. The reaction also occurs between Safranine T and CdS. At the same time, the Fluorescence of ST is quenched by forming ST -CdS ground state complex. Chapter 6, CdS QDs modified by chitosan and polyethyleneimine can be quenched by Cu~(2+). According to the experimental result, we develop the novel sensor for Cu~(2+).
研究结果,吡啰红与CdS之间作用形式是染料聚集在CdS的表面使得CdS不易聚集,但同时也降低了CdS的发光的量子效率;罗丹明B、罗丹明6G、丁基罗丹明B均与CdS之间存在能量转移,位阻效应使得能量转移效率最高的BRhB的相对荧光强度增大最小;中性红与CdS的能量转移效率更高,同时推测可能使CdS-TGA上的-COOH与部分NR的-NH_2发生偶联导致粒子变大而发生荧光光谱的红移;番红花红与CdS是相互荧光猝灭,可能是ST的-NH_2与CdS-TGA上的-COOH发生偶联使得纳米粒子变大以及二者形成基态复合物的共同作用的影响。

Of them 25 cases of oral cancer (G1-2) were randomly divided into trail and control group . The remained 11 cases of nasopharyngeal and maxillary sinus cancer (NPC-MSC, mainly G3-4) were attributed to a third group (1st course: sBRM, then 2nd course: IAC). The order of drug-use of sBRM is: pre-immunomodulation of the reactivity of patient low-dose CTX and PolyI∶C, then in- juring tumor and thereby modulation of its immunogeneity (DDP-PYM regimen , thereafter, reaction enhancement modu- lation [low-dose rhuIL-2, Cimetidine and Indomethacin ] . All drugs, except for CTX, PolyI∶C and Indo, were fractionally delivered in a manner of continously infution in 8-10 hours via a retaining intra-external carotid artery catheter CAVAFIX 335 SPLITTOCAN G14, B.

The project change in the Hongkong film industry can be summed up as follows. It is Chuang-tzu's Test in His Wife that makes a beginning of the Hongkong film industry. While Husband's Coming in Late, reviving traditional Cantonese films, unseals the markets of Singapore and Malaysia, Liang Shanbo and Zhu Yingtai completely occupies the market of Taiwan, the largest oversea market except for the mainland. And after Seventy-Two Tenants, as a sign of new industry, combines the Mandarin film with the Cantonese film, New Dragon Tavern goes further to find a new way to the market of the mainland. Not only do Stephen Chow's films become repeatedly a solace in downturn but also the blockbusters in the Chinese language film have a global integration, thus starting the second upsurge of the Eastern knight-errant film.
