In Chapter 5,the pyrolysis of substituted six-membered ring model compound 4-methyl pyridine has been investigated.Instead of detail theoretical analysis of the reaction mechanism,the general results have been proposed from the products distribution and the combination of the pyrolysis investigation of its analogous pyridine.The major products are H_2,C_2H_2,C_4H_2,C_3H_3N and HCN,here HCN is not a primary initial product at low extent of decomposition.The mole fraction profiles of products have been obtained from the near threshold ionization.The pyrolysis of 4-methyl pyridine is initiated from the methyl abstraction and hydrogen abstraction procedures which are associated with the understanding of the soot formation and the NOX precursor correspondingly.

主要产物为H_2，C_2H_2，C_4H_2，C_3H_3N和HCN，其中HCN为非低温时的热解产物；通过近阈值电离并导出物种随温度变化的摩尔分数曲线，更详细地定量地描述了产物随温度的变化。4-甲基吡啶热解主要从母体脱甲基和脱氢两个初始反应出发，一种趋势是形成大质量数的苯并或杂环的多环化合物，有助于了解炭黑形成过程中的复杂化学过程；另一趋势是开环生成小的碳氢和腈类物质，实验得出的含氮物质的种类及随温度变化有助于了解NO_x的前驱物质的形成及其变化规律。

In the cyclization process,α-acylamino radicals preferred to attack acylsilanes from the face opposite to the β-substituent, and the stereoselectivity of the bridgehead is excellent. The orientation of the hydroxy group formed in the cyclization process was mainly exo.

生物碱架桥上立体化学的建立，可透过环上取代基立体障碍的影响，使得环化过程只会从立障较小的一面进行，因此可得到单一立体化学的结果，而环化所形成的羟基则是以exo的产物为主。

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.

将其中25例晚期口腔高、中分化鳞癌病人随机分为实验治疗（12例）和对照治疗（13例）两组，实验组采用sBRM疗法，具体用药为：先用小剂量环磷酰胺和聚肌胞对机体反应性作预调变，然后用低剂量DDP-PYM化疗杀伤&致创&癌细胞，使其免疫原性增强并借之诱导肿瘤浸润淋巴细胞，化疗结束后续用小剂量rhuIL-2激活和扩增TIL，特别是其中的T细胞，并借助小剂量西咪替丁、消炎痛调节机体以原发灶为中心的癌受创相关反应。

Compared with ring reducer which had same power, the balance ring reducer had many functions, such as low vibration noise, low cost and less production difficulty.
