By Giemsa--C technique, the chromosomes of Aegilops tauschii (85A-34) and Hordeum vulgare (H2) and Ae.tauschii- H.vulgare amphidiploid were all produced clear bands, the terminal band, centromeric band, secondary constrition band and rich intercalary bands were displayed distinctly, thus the corresponding Giemsa-C banding patterns were confirmed.

利用Giemsa--C带显带技术，节节麦、大麦、节节麦-大麦双二倍体都显示出了清晰的带纹，都具有端带、着丝点带、随体带和丰富的中间带，相应的确定了它们的Giemsa--C带核型。

Amino desacetoxycephalosporanic acid (7 - ADCA) is an ampholyte.

7-氨基去乙酰氧基头孢霉烷酸是两性化合物，从等电点两侧改变溶液的 p H值都可以产生过饱和度并结晶得到晶体产品，本文对 7-ADCA两种方法结晶的初级成核过程进行了研究。

Sekanina, who has studied how Comet Shoemaker-Levy 9 and others have split apart, has concluded that the events that create these multiple nuclei often occur far from the Sun, even around aphelion.

Sekanina曾经研究过Shoemaker-Levy 9 彗星（1994年撞击木星的彗星——译者注）和其它彗星是如何分裂的。他得出结论，产生这些多重彗核的事件经常发生在远离太阳处，甚至可以是远日点。

The arithmetic of the point charges integral is similar to that of nuclear attraction potential.

前者的计算类似于核吸引积分的单电子积分，后者可以通过点群对称性操作从原子簇内的积分矩阵元得到。

Methods:One hundred patients underwent pallidotomy and thalamotomy for Parkinson's disease by means of microelectrode recording used as intraoperative target localization between Oct. 1997 and Apr. 1998. The patients were assessed by means of UPDRS.

采用微电极细胞电生理记录技术进行术中靶点监测，对100例帕金森病患者行苍白球腹后部(96例)和丘脑腹外侧核(4例)毁损术，患者术前及术后评估采用UPDRS积分，术中靶点更换率为87%。

METHODS:The micronucleus test of Vicia faba root tip cell was used to detect the water quality,and to survey the chemical oxygen demand.The micronuclear rates and Pollution Index were determined and the F-test was used to evaluate the difference in micronuclear rates among different samples.

材料与方法：用蚕豆根尖细胞微核技术对各采样点水样进行监测，并对各水样进行化学需氧量(chemical oxygen demand，CODcr)的测定，统计分析各采样点水样的蚕豆根尖细胞微核千分率及污染指数。

The chromosomes of Aegilops tauschii (85A-34) are the central centric chromosomes except that the chromosomes of No.5 is the submedian centric chromosome.Its kartype formula is 2n=2x=14=12m+2sm(2SAT).

节节麦（85A-34）除第5对染色体外都为中部着丝点染色体，第5对染色体为亚中部着丝点染色体且为具随体染色体，其核型公式为：2n=2x=14＝12m＋2sm(2SAT)。

To study the significance of using mutiple targes in intractale psychosis, 120 patients were treated by stereotactic technique combined with CT, MRI, microelectrode, and electric impedance methods with bilateral multiple nuclei lesioning by radio frequency thermocoagulation.

在立体定向基础上，应用CT、MRI、微电极和电阻值联合的多元化定位方法，对 12 0例难治性精神病患者，采用不同核团组合的双侧多靶点技术进行射频热凝治疗，应用CGI、BPRS、PANSS等精神病量表进行术前、术后的对照分析，以探讨不同靶点组合对难治性精神病的治疗意义。
