To discover new strobilurin analogues with high pesticidal activity, a series of new strobilurin derivatives containing substituted pyrazole and pyrimide ring, which included 124 novel compounds (73 compounds containing substituted pyrazole ring and 51 compounds containing substituted pyrimide ring) were designed and synthesized. In addition, 36 new intermediates were synthesized. Their structures were characterized by 1H NMR and elemental analysis, partial compounds were characterized by MS and IR once again.

为了发现具有更好生物活性的新型Strobilurin类化合物,本论文在详尽总结文献的基础上,设计并合成了含吡唑和嘧啶环的新型Strobilurin类化合物124个,其中含吡唑环的新加热管型Strobilurin类化合物73个,含嘧啶环的新型Strob 加热管 ilurin类化合物51个;未见文献报道的中间体36个,所合成的化合物经过1H NMR、IR、LC-MS或元素分析等确定了结构。

Results 17 patients reported in the literature had primary bronchogenic carcinoma with metastases of phalanges of fingers as its first symptom. 7 patients' metastatic lesions located in their phalanges of left hands, 9 right hands and 1 both hands. The distribution of the quantity of the phalangeal metastases between two hands was almost equal. 3 patients' metastatic lesions were situated in proximal phalanges of fingers, and the rest in distal. 6 patients' ill fingers had had trauma history.

结果 在文献报道的以单纯指骨转移为首发症状的17例原发性肺癌的病人中,其转移病灶位于左手指骨者7例,右手指骨者9例,双手指骨者1例,指骨转移病灶的数量在两手之间的分布大致相等,除3例病人其转移病灶位于近节指骨外,其余病人的转移病灶均位于其末节指骨;有6例病人的患病手指既往曾有外伤史。

In this paper, we summarize the synthetic methods, structure features and photophysical properties of WSCPs developed in recent ten years, and their applications in a new generation of optoelectronic devices and bio-chemical detection. On this basis, we point out the existent problems in the present research and applications of WSCPs,and also give a perspective on their future.

本文总结了近10年来报道的水溶性共轭聚电解质的结构特点和合成方法,以及对不同化学或物理条件下光物理性质的研究,归纳了它们在新一代光电器件制作和荧光传感中的应用,并在此基础上提出了水溶性共轭聚电解质研究中尚待解决的问题,并展望了水溶性共轭聚电解质的应用前景。

At constant viscosity, by increasing the liquid flow rate, the liquid film's velocity is increased; at the same experiment condition, the frequency of the liquid film is same at the same radial direction; the air current has minimum effect on liquid film bottom flow velocity, while it has an obvious effect on liquid film surface flow velocity. The longer the distance between liquid film and the inlet, the lower the pulsatory frequency and longer the wavelength.

在粘度基本不变的情况下,随着液体质量流率的增加,液膜流动速度随之增加;在同一个实验条件下,沿圆管径向各质点的频率基本保持不变;气流场速度对液膜底层流动速度影响很小,对于液膜表面流动速度有着较大的影响;沿液膜流动方向,液膜的脉动速度逐渐增加,脉动频率降低,脉动波长变长,与报道的通过快速摄像得到的液膜发展趋势一致,证实用PDA研究液膜流动是可行的。

Most striking about the results of the study is that its 15-year BRFS rate of 74% is higher than the 66% BRFS rate reported for radical retropubic prostatectomy in a recent study conducted at Johns Hopkins Hospital in Baltimore, as well as the 68% BRFS reported for RRP by researchers at Washington University in St.

这项研究的最显著特征就是其15 年BRFS 比率达到了74%,高于新近在巴的摩尔的约翰斯·霍普金斯医院开展的耻骨后前列腺根治切除术研究所报道的66%以及圣·路易斯的华盛顿大学开展同类研究时所获得68%。

In this paper, active groups terminated silicane was used to react with the hydroxyls of bisphenol A epoxy resins, that introduced organic silicon without consuming epoxy groups. This modifying process improved the combining degree of the cured resin, so both the toughness and the other characters (as strength, thermal resistance) were all could be improved.

为此本论文采用国内外文献中尚未见报道的、带活性基团的有机硅来改性双酚A型环氧树脂,通过端基基团与环氧链上的羟基反应生成大键能的Si-O键的方式来引进有机硅,改性过程中不仅不消耗环氧基,并且还提高了树脂固化物的交联密度,所以既能增韧树脂,又能提高其耐热、耐冲击等各项性能。

In order to get the information of interaction between metal complex and DNA and select metal complexes which can cleave DNA effectively, twenty seven transition metal complexes containing O/N coordinate atoms have been synthesized in this thesis. We report the synthesis, crystal structure and properties of the complexes. One of the complexes is the first μ〓-oxalato tetranuclear Cu complex, in which there is ferromagnetic interaction between the copper atoms bridged by oxalate ions. Two trinuclear copper complexes containing partial cubane Cu〓O〓 cores have been synthesized and discussed the magnetic properties.

为了解金属配合物与DNA的相互作用及筛选能有效切割DNA的金属配合物,为无机药物合成及应用提供基础信息,本文利用十个含N、O原子的多齿配体设计合成了二十七个未见文献报道的过渡金属配合物,并解析了它们的晶体结构:其中包括首例μ〓-草酸根的四核铜配合物;合成了两个具有μ〓-OH〓三核缺角立方烷结构的Cu配合物;以HCBP衍生物为配体合成了七个过渡金属配合物;以SCN〓、N〓,C〓O〓等为桥联配体,以dmpyen为端基配体合成了十一个配合物。

The transplant of seedling should be processed after the upgrowth of leaves and root.By using the GC-MS, the chemical composition in root of Valeriana amurensis was analyzed. The avilid components in root of different provenance were similar, and the contents of effective composition in roots were depended on the provenance. Meanwhile, P-Panasinsene was founded in root of Valeriana amurensis for the first time.

用水蒸气蒸馏法提取黑水缬草根部挥发油,并用GC-MS联用仪对其化学成分进行了分析鉴定,结果表明:不同生境、不同产地、不同年份、不同生长方式的黑水缬草根部挥发油的主要化学成分大致相同,人工栽培的黑水缬草有效成分的含量高于野生黑水缬草有效成分的含量,并从中分离出一种在相关文献中未见报道的化学成分—β-人参烯。

Prowling the streets, a cruel gray fog engulfing Wall Street, a "war free" edition of The New York Times, a character stranded on the dying International Space Station, strange and valuable vaselike objects called chaldrons, colossal cheeseburgers and some extremely potent marijuana.

在街上窜来窜去,一层笼罩着华尔街的灰蒙蒙的雾,没有战争报道的纽约时报,一个在即将完蛋的国际空间站上进退两难的人,一种叫做查尔特隆的珍奇花瓶,巨大的三明治和效力强劲的大麻。
