Recordings from the STN exhibited an increase in the background activity and an irregular firing pattern, with a mean rate of (49±13) Hz. The mean cell density was (58±14) cells /mm, with an average length from upper bounder to lower bounder of (58±08) mm. The movementrelated cells were located primarily in the dorsolateral sector of the STN, with the leg area located medial along the mediolateral axis and centrally along the anteroposterior axis, compared with the arm area.

Based on the review of the description of subtropical high and the research on its formation, fluctuation characteristics and physical mechanisms, it is found that the subtropical high is refered to the area where pressure is relatively larger. Its formation is due to the existence of mean meridional circulation that accumulates air mass to subtropical areas. The subtropical high is belt-like with meridionally non-uniform feature and this is a zonal mean point of view.
通过对副高的描述、形成及演变特征和物理机理的研究进行回顾,认为:副高是相对的气压的高值,是由于平均经圈环流的存在,使得有空气质量在副热带地区的堆积而形成的,成为带状,表现出在经度方向的不均匀,这是一种纬向平均的观点;同时,在这个平均的高压带上常常有闭合的单体存在,表现出纬向的不均匀。

Density Functional Theory method was used to optimize the geometries of 209 PCDE molecules, 209 PBDE molecules and 75 PCDD molecules at the B3LYP/6-31G* level. Using computed structural parameters as theoretical descriptors, the forward stepwise multiple regression technique was adopted to obtain QSPR models of environmental partition properties for these POPs by using GQSARF 2.0 and SPSS12.0 for windows programs. The obtained QSPR models are as follows:(1) QSPR models for predicting subcooled liquid vapor pressure, n-octanol/water partition coefficients lgK_(ow and subcooled liquid water solubilities -lgS_(w,l of PCDEs, of which correlative coefficients (R~2) are 0.988, 0.958 and 0.959 and the root-mean-square-error of estimation are 0.134, 0.116 and 0.327 respectively.(2) QSPR models of lgPL and n-octanol/air partition coefficients lgK_(oa for PBDEs, which both contain three structural parameters. The values of R2 for the two models are both 0.997 while the values of RMSEE are 0.073 and 0.062 respectively.(3) QSPR models of lgKow and–lgS_ for PCDEs, which both have one variable (mean molecular polarizability,α). The values of R~2 for the two models are 0.978 and 0.866 and the values of RMSEE are 0.300 and 0.270 respectively.(4) The molecular structures of 24 substituted naphthaline compounds were optimized using Hartree-Fock and DFT methods at four different levels and the same means was used to obtain four three-parameter (EHOMO, q~+ andα) QSPR models of lgK_. The model at the HF/6-311G** level is the best one of which R2 is 0.9662 and RMSEE is 0.380.(5) QSPR study for environmental partition properties of PCDEs was also performed using position of Cl substitution method in which simple parameters of substitution position were taken as descriptors. The multiple linear regression was performed with GQSARF 2.0 and SSPS 12.0 for windows programs to obtain QSPR models of lgP_L, lgK_ and–lgS_ for PCDEs of which R~2 are 0.991, 0.983 and 0.965 and RMSEE are 0.311, 0.100 and 0.300 respectively.

It was translated into Latin in the 12th century as Algoritmi de numero Indorum (al-Daffa 1977), which title was likely intended to mean " Algoritmus on the numbers of the Indians", where "Algoritmi" was the translator's rendition of the author's name in the genitive case; but people misunderstanding the title treated Algoritmi as a Latin plural and this led to the word "algorithm" coming to mean "calculation method".
它被翻译成拉丁文于12世纪的Algoritmi日号码Indorum (铝Daffa 1977年),其中冠军很可能意味着& Algoritmus的人数印度人&,其中& Algoritmi &是译者的移交逃犯的作者姓名的所有格案件;但人们误解的标题处理Algoritmi作为拉丁美洲多元,这导致了单词&算法&(拉丁文algorismus )来指&计算方法&。
