查询词典 ortho

The Second Medicine, also called Ortho-Molecular Medicine, came into being with the invention of microscopes, especially the discovery of bacteria in the middle 18th Century. At that time, people discovered surprisingly that many diseases originally were caused by some microorganism and began to wonder how to prevent the germina entering human body.

第二医学又称分子矫正医学那是在发明显微镜，特别是18世纪中叶发现细菌之后，才发展起来的当时人们惊奇地发现，原来许多疾病竟是一些小小的微生物作怪的结果那么，能不能防止这些病菌侵入我们的机体呢？

The results indicate that thermal stabilities and decomposition mechanisms of the title compounds derived from the BDE, Ea and static electronic parameters are basically consistent. Homolysis of the N—NO2 bond is the initial step in the thermolysis of the title compounds, the meta-isomers are more stable than the para-isomers, and the ortho-isomers are the most sensitive.

结果表明，由BDE、Ea和静态电子结构参数推断的标题物热稳定性和热解机理的结论基本是一致的，N-NO2键均裂是标题物的热解引发步骤，间位取代异构体较对位取代异构体稳定，而邻位取代的异构体稳定性最差。

The yields were better when DHPCE with nitro group in meta or ortho position of the benzene ring were hydrolyzed in basic conditions, while the hydrogenolysis and acidic reactions gave very poor yields.

当苯环的间位和对位存在硝基，碱性水解时，在二氢吡啶环的3位引入氯乙醇的酯能得到较好的收率；酸性水解和氢解法则不宜用来合成ADHPA。

She's been to an ortho,two neuros,and an immunologist.

她接受过整形医生两位神经科医生和免疫学家的治疗

And the ortho-image before and after the landside has also been acquired using high-resolution satelite image and proper image-disposal method.

在获取滑坡前后高分辨率卫星数据的基本上，采用合理的图像处理技术，获得了滑坡前后正射影像图。

In Chapter 6, the symmetric ortho-symmetric solution of the matrix equation AXAT = Bon the linear manifold S ={X 6 SPRnxn\XZ = Y, ZjYt = Y?

运用矩阵对的标准相关分解，给出了上述两类线性流形上矩阵方程A~TXA=B的双对称最小二乘解的通解表达式。

In the presence of cobalt ion, nearly 100% selectivity to ortho-chloroanilinewas achieved over PVP-Ru/Pt colloids at 100% conversion of o-CNB, with an activity twoorders of magnitude higher than that of monometallic PVP-Ru colloid.

当在反应体系中加入钴离子时，邻氯硝基苯被高选择性地氢化为邻氯苯胺(邻氯硝基苯转化率为100%时，选择性～100％)，同时，反应的活性比PVP-Ru单金属胶体提高了约两个数量级。

The bulky ortho-brominated aryl groups are implanted to create nonplanarity around amino center. Thus, the effective conjugation length to the protonation site is shortened and the energy gap between neutral and protonated forms is narrowed. The protonation can only occur at the nitrogen atom of the benzothiazole and the temperature variation disturbs the equilibrium between the neutral and monocation and the reverible thermochromic effect can thus be achieved.

在邻位的位置引入立体阻碍大的溴原子，进而控制质子化过程的酸碱平衡只发生在 benzothiazole 上的氮原子上，企图达到只有中性分子，与单阳离子两种稳定的形式存在，经由外界的刺激下，例如温度或酸的量的改变，促使逆反应的发生，而达到热致变色的效果。

It was found that the nitration reaction has a high ortho-selectivity, and a high conversion could be achieved.

结果发现在此微乳体系中，苯酚的硝化具有明显的邻位选择性，而苯酚氧化等副反应明显减少，实现了高产率。
