产下

As the hips are usually smaller than the head, so may be relatively rapid decline, but not for the head is also very easy to output, and consider it premature to production timing, so as to avoid birth trauma or head down in the final crisis of Health, If there is any way to extend the middle class must be an early Caesarean section.

然而，在目前的环境下，个人认为第二胎以上，没有剖腹产的孕妇，在胎儿不大，孕妇本身也没有并发症的情形下，臀位也就是"纯臀位"没有直立腿的情形，在产程正常时，还是可以考虑阴道生产，不过事前与主治医师讨论利弊后再下决定，是最佳之道。

The reaction of α-hydroxyketone with Michael acceptor nitroalkene.was studied. After many experiments, we then found that in the presence of Zn2 and cinchonine, the α-hydroxyketone could successfully react with nitroalkene. Under our optimized condition, we gained the 95% yield of product with the ratio of syn : anti of 3:1 and 72% ee value for syn-product.

In this thesis, investigations focused on heteropoly acids-catalyzed C-C and C-N bond formation reactions and the synthesis of xanthenediones and acridinediones under thermal conditions are described.1.12-Phosphotungstic acid has been used as an efficient,eco-friendly,and air- and moisture-stable catalyst to promote the direct dehydrative substitution of the hydroxy group of benzylic and allylic alcohols with variousβ-dicarbonyl compounds.

本篇论文主要描述了杂多酸催化下的C-C和C-N键的生成，以及无溶剂直接加热下合成十氢氧杂蒽二酮和9-芳基十氢吖啶二酮。主要内容如下：1。在磷钨酸催化下，1，3-二羰基化合物与醇能够顺利偶合，脱除一分子的水，生成烷基化的1，3-二羰基化合物。反应在甲苯中进行时，二芳基甲醇能与各类1，3-二羰基化合物反应，成率很高；但对于1-苯乙醇，只能得到很低的产率。

The results showed that resistant gene Ht in F1 heterozygote was the most effective on controlling spots number and size; all monogene in heterozygote could produce spore by moisture culture and resistant gene Ht1 was the most effective; resistant gene Ht1 in medium level, Ht3 in high level, and Ht in low level of vertical resistance of heterozygote, were the most effective on controlling spots spread; while Ht2 in high level of vertical resistance of heterozygote was the most ineffective on controlling spots spread; and all resistant monogene in heterozygote showed superior to their parents on controlling incubation period and gene Ht was more significant than other genes.

结果表明，抗性单基因Ht处于F1代杂合状态时，控制病斑数和病斑面积的效应最强；单基因处于杂合状态时，湿培48h病斑全部能产生分生孢子，且处于同一水平抗性杂合状态时，Ht1控制产孢量的效应最强；Ht1处于中水平、Ht3处于高水平和Ht、处于低水平垂直抗性杂合状态下，控制病斑扩展效应最强；而Ht2处于高水平垂直抗性杂合状态下，控制病斑扩展效应最弱；抗性单基因处于杂合状态下，控制潜伏期多表现超亲现象，Ht控制病害潜伏期比其它单基因显著。

By establishing the large scale plate cutting center in a steelworks, the steelworks, plate cutting center , and users are related using the computer network.

Usually the work of paediatricians often encountered in clinical treatment in children: 2-month-old baby is not laugh, or four five-month-old baby will not rise up the first non-erect, or more than 3-year-old child to walk properly, toe down, heel and could not walk forward, walking instability, the majority of children with mothers who have children with a detailed statement of the history of neonatal asphyxia and abnormal birth processes, such as breech births, adequate presentation production, mothers had pregnancy-induced hypertension or fetal heart rate or pre-B ultra-poor can be seen with cord around neck, wrapped around limbs or broken membrane as early as more than 12 hours and even some more than three days.

Due to the usage of preservative added on the timber materials, the necessity for the officers to choose timber materials with better anti-termite property might be reduced. So, whether to use timbers produced in Taiwan, China-fir imported from China or the Japanese cedar imported from Japan was mainly determined by the trade policy of the government and the market structure.
