无法鉴定的

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a"和4a"也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。

RESULTS Early-instar larvae could not be identified, but all fourth-instar larvae identified were members of the Culex pipiens complex.

结果 初龄幼虫无法确定，但所有四龄幼虫鉴定成员的库蚊复杂。

Due to the existence of the ancient porcelain copies andmodem fakement, work of identification becomes the principal problem of the collection.

这三个方面的基本要求把握好了，无论在物质方面还是精神方面都能从中得到丰厚的回报，而如果把握得不好，往往留下难以挽回的经济损失和无法弥补的心理缺憾。这里概括地从整体上谈谈古代瓷器的鉴定方法。

When the ancients couldn't judge content of gold in rocks with naked eyes, they beat ores into mash in stone mortar, put them into trencher, panned them in water, and discarded coarse materials.

当古人用肉眼无法鉴定矿石中金的含量多少时，则将矿石在石臼中捣碎，装入木

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a&和4a&也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。

We use this technology to measure some rock and oil sample taken from Liaohe or Tarim basin. We identified many series of biomarker with dividing-era significance. These series are C26 steranes, C30 methylsteranes; and methly hopanoid alkanes, hexacyclic hopanoid alkanes, which two series were measured first by our laboratory in China.

本论文建立地球化学样品GOMS／MS分析方法；并对辽河盆地和塔里木盆地岩石及原油样品进行GC／MS／MS分析，鉴定出多个系列具有划时代意义的生标组分，这些组分是用GC／MS技术无法检测的极微量的生标组分：C26降胆甾烷系列、C30甲基甾烷系列等：还有高碳数甲基藿烷系列和六环藿烷系列见图1，图2，在国内被我们实验室首次检出。

The Science of Human Nature PREFACE The born of this book, The Science of Human Nature, has thoroughly revoluted traditional psychology ideas, and fundamentally overthrown traditional psychology theories.

网上求助《人性学》一书的问世彻底的改变了传统心理学理念，从根本上推翻了传统心理学理论，我本想将此书出版，但在出版社审稿时却遇到了意想不到的麻烦，无论是编辑还是心理学家都无法给这部书作出任何评价与鉴定，如果不经某些专业人士的鉴定，这部书就出版不了。

Results By MSHA/MRHA, the fimbriae of 4 of the 5 isolates were identified as type Ⅲ, and the rest one as undefined type. However, by PCR, all the fimbriae of 5 isolates were identified as type Ⅲ.

结果 MSHA/MRHA方法鉴定其中的4株菌具有Ⅲ型菌毛，另外1株无法鉴别，而PCR方法鉴定5株菌均具有Ⅲ型菌毛。

The existence of hybrids, and the difficulty of identification of many individual marsh harriers due to extensive individual variation, complex ageing and incomplete knowledge, means that it is not possible to identify all individuals confidently.

杂交个体的存在和鉴定许多鹞属猛禽个体的困难在于许多的个体变异、复杂的年龄构成、不完善的知识，这就意味着无法准确的鉴定所有的鹞属猛禽个体。
