Anilido-imino nickel complex 1 {(C6H3Me2-2,6)N=CH-5-NO2-C6H3N (C6H3Me2-2,6)}NiBr was first synthesized, and its catalytic behavior toward polymerizations of norbornene and ethylene in the presense of methylaluminoxane were investigated in detail. The complex activated with methylaluminoxane exhibited high activities for norbornene polymerization.

Based on＂The Data Bank System of the Standard Phonetic Features of Different Level in PSC＂, the thesis analyzes the variants of affricative versus fricative in syllables: z, c ,s - zh, ch, sh - j, q, x which are obscure in physiology; analyzes timbre phonetic variants aroused from the different match of seven main simple vowels and initials as well as the tonal patterns with the help of drawing the synthetic spectrograph and pitch spectrograph. So that the data can be offered to describe phonemes in 396 syllables in common use according to the acoustic analysis.

本文在"普通话水平测试各等级标准语言特征数据库系统"的支持下，通过制作396个常用音节语音样本的音高图和综合语图，考察在普通话教学和测试中从生理角度难以准确把握的一组仅有细微差异的塞擦音和擦音声母z、c、s-zh、ch、sh-j、q、x在音节拼合中的变体；考察7个主要单元音在与不同声母拼合构成的音节中音质上的变化模式；考察四个声调的变化形式，力图从语音声学物理特征角度的分析中为普通话常用音节音位语音规范度的描写提供客观的数据说明。

The effects, of protection and treatment with, combined Ch, NaF and a trophie were significantly better than that with atropine alone. In isolated phrenic nerve-diaphragm preparation of rat, isolated jejuneal preparation of, guinea pig, and the metabolic experiment of rat liver, the results of the, assay on the rat blood ChE activity indicated that antidotal effect of NaF may be due to the antidese...

大鼠离体膈神经膈肌、豚鼠离体空肠和大鼠肝脏代谢实验及对大鼠全血胆碱酯酶活力测定的结果表明，NaF的抗毒作用可能是由于其对神经肌肉接头和/或神经节中的N受体的抗脱敏作用；而Ch则可能通过其对ChE的保护和/或加速被抑制ChE的复能，阻碍Ach到达M受体部位而发挥作用。

Effects of microorganism starter culture on the lipid of dry-cured fermented duck;2. Almond,walnut,peanut and almond are abundant in protein and lipid with CH stretching vibration nearby 2 914 cm-1,2 847 cm-1and C=O stretching vibration nearby 1 742 cm-1 in their infrared spectrum;while wolfberry fruit, red date,raisin and fig are abundant in pdysaccharide and protein conte.

巴旦木、核桃仁、花生仁、带壳杏仁富含蛋白质和脂类物质，红外图谱显示出在2 914，2 847cm-1附近的CH伸缩振动和1 742 cm-1附近的C=O伸缩振动；枸杞子、红枣、葡萄干和无花果干富含多糖、蛋白类物质，其红外图谱显示出在3 370 cm-1附近的OH变形振动、NH伸缩振动和2 920 cm-1附近的CH伸缩振动。

In Slavic languages using the Latin alphabet, the sh and ch sounds, single letters in Cyrillic, become head-splitting combinations of sz, cz, ci, si, s, s, and c, as in the Polish word szczesliwy.

在斯拉夫语种中使用拉丁文字母表，sh和ch的发音(拿俄语来举个例子，俄语里发类似这两个音的字母有两个，但在英文里是没法分的，因为sh和ch在英文里发音是一样的，难以反映出俄语里两个相近字母的发音区别)，以及西里尔文里的单音字母，就变成了令人头痛的

Due to the suppression of reverse water gas shift reaction by adding steam in feed gas, more CO〓 participated in and promoted CO〓 reforming of CH〓 reaction, higher catalytic activity and less carbon deposition were obtained. On the surface of used catalyst there were two kinds of carbon species deposited on catalyst, one was decomposed CH〓 fragment, and the another was graphiticlike carbon.

在反应后催化剂表面有两类碳物种，一类在250～350℃出现的少量α-碳，应主要是活性高的CH〓解离碎片，一类是在700℃附近出现的β-碳，应是导致催化剂失活的类石墨化碳。
