The signal drop at globus pallidus and putamen on two sequences were evaluated by two neuroradiolgists who did not know the clinical features of the patients. A hypointensity in the dorsolateral putamen equal to or lower than that in globus pallidus was taken into account as the main clue to differentiate the two diseases.

For this final stage of information literacy in the classroom, the teacher can use a rubric

先让学生在网络上寻找有"关小组讨论"的资料，藉以了解此项评核的内容和评核目的+ 2。教师为学生分组(每组4-5人，每组均有一些能力较好的和能力较弱的同学)+ 3。教师给予一些话题作为小组讨论的内容

The world's nuclear power plants in the nuclear island and conventional SAFETY VALVES island a number of important nuclear grade, non-nuclear grade valves, such as the pilot-type safety valve, the main steam isolation valves, regulating valves and other valves of nuclear power technology and markets are well-known nuclear power valves company monopolies, and the price very high.

世界上核电站中的核岛和常规岛中许多重要的核级、非核级阀门，如先导式安全阀、主蒸气隔离阀、调节阀等的核电阀门技术和市场均被著名的核电阀门公司所垄断，而且价格十分昂贵。Introduction of nuclear power valves 是由中国疏水阀网提供的国际阀门新闻，译文仅供参考。另外，中国疏水阀网还提供相关产品搜索：疏水阀型号、疏水阀价格、疏水阀技术、疏水阀新闻、疏水阀生产商等。

On the one hand, one benzen ring of stilbene was substituted by one pyridine ring for the purpose of evaluating the bioactivities of azastilbenes. On the other hand, some stilbene derivatives with different substituents in different sites were designed for the study of SAR.

一，以吡啶环替代母核的一个苯环，考察分子中引入氮原子对活性的影响；二，改变母核上的取代基类型及取代位点，考察取代基在构效关系中的影响规律。

CH3OH could attack the phosphor atom in 1,3,2-dioxaphopholane of compiound (1) to give O-methyl O-hydroxyethyl-O-phthalimidoethyl thiophosphate in 85% yield; in the presence of potassium hydroxide aryl selenol could attack the carbon atom in 1,3,2-diox-aphopholane of the cyclic phospholipid conjugate of N^1-(2-furanidyl)-N^3--5-fluorouracil to give the corresponding product of ring-opening in high yields.

在室温下，以异丙醇作溶剂，苯硒酚与化合物2不反应。在氢氧化钾存在下，以异丙醇／水作溶剂（体积比20：1，在室温下，硒酚可以有效地进攻中化合物2中1，3，2-二氧磷杂环戊烷中的碳原子生成相应的开环产物。按照这一反应条件，顺利实现了硒酚对N^1-（2-呋喃基）-N^3-羟烷基-5-氟脲嘧啶硫代环甘油磷脂缀合物的亲核开环，生成甘油骨架的端碳原子上带有芳硒基新颖的磷脂核苷缀合物。

The result indicate that: the electrodeposition of zinc on nickel and tungsten substrates involves instantaneous three-dimensional nucleation. The coating is the best when the current density is 4mA/cm2 and the temperature is 80 ℃. The coating by the method of the impulse electrodeposition is better than the direct current electrodeposition. Especially when f is 100Hz, ton/toff is 2/8 and J is 8mA/cm2, the coating is clean and uniformity. The crystal size is nearly 0.3μ m .

结果表明：阴极反应为准可逆反应，锌离子在镍电极和钨电极上形核是三维瞬时形核半球形扩散长大过程，直流电流密度为4mA/cm2，温度为80 ℃时，镀层质量最好；脉冲电沉积得到的镀层要优于直流电沉积得到的镀层，尤其在脉冲宽度为2ms，脉冲间隔为8ms，电流密度为8mA/cm2时，得到的镀层光滑而均匀，颗粒大小接近0.3μm。
