未取样的

Since the summer of this year, the local emergence of dry pine stumpage previous years the phenomenon of a relatively large increase, while in some samples of dead pine wood nematode was first detected to be, Wuyi County, is enhanced search, in particular is to strengthen the right pot Mountain Provincial Forest Park, Tong-Qin town, the new Zhai Town, and other key regions in the dead pine forests microscopy sample separation, so far the county has accumulated more than 20 batches of samples microscopy showed no pine wood nematode.

今年入夏以来，当地出现了松木枯立木比往年有较大幅度增多的现象，同时在一些枯死松木样品中首次检出了拟松材线虫，武义县更是加强了查检工作，尤其是加强了对壶山省级森林公园、桐琴镇、新宅镇等重点地域山林中枯死松木的采样分离镜检，至今全县已累计取样镜检20多批次，未发现有松材线虫。

The families Cercidiphyllaceae, Daphniphyllaceae, Hamamelidaceae and Saxifragaceae are closely located, while the relationships among them remain unsolved even if more repres...

尽管增加了金缕梅科的取样密度，它们之间进一步的关系仍未得到分辨，结合它们的形态特征，连香树科和交让木科应置于金缕梅目内。rbcL基因树上反映出传统的&低等&金缕梅类成员领春木科与毛茛类植物聚在一起；悬铃木科与昆栏树科和水青树科关系较近，而与金缕梅科关系较远；杜仲科与低等金缕类的核心科———金缕梅科的关系似乎较除连香树科之外的其它低等金缕类成员近。低等金缕类植物由一些古老、孤立的科组成，且是多系的。

This article studied differences in postpartum fatigue and birth outcomes between women who pushed immediately and those who delayed pushing during the second stage of labor. Data were collected from primiparous women in their 38th to 42nd gestational week who did not receive epidural analgesia during labor and were free of complications during pregnancy. Using a quasi-experimental design, 72 participants selected by convenient sampling were assigned based on individual participant's preference to either an experimental or control group. For the experimental group, pushing was delayed until the point after full cervical dilation at which the mother felt a strong physical pushing reflex, the fetal head had both descended to at least the +1 level in the pelvis and turned to the occiput anterior position, and uterine contractions were at least 30 mmHg. For the control group, the physician instructed mothers to begin pushing after full cervical dilation at the point when the fetal head was in the occiput anterior position and uterine contractions were at least 30 mmHg.

本研究目的在探讨初产妇女第二产程立即用力与延迟用力对产后疲惫及生产结果的影响，收案对象为怀孕38-42周初产妇女、待产期间未施打硬脊膜外麻醉，且怀孕期间无任何合并症，於待产期间向其解释研究目的及收案方法后予以收案，采类实验设计法，以方便取样并依个案之意愿分派於实验组及控制组，实验组於子宫颈完全扩张后等到强烈想用力的感觉、胎头位到达坐骨棘连线下1公分以下、胎头位置转到枕前位、子宫收缩规律强度至少30mmHg才教导向下用力；控制组於子宫颈完全扩张后即教导向下用力，共收案72位。

Quarantine and trade records of live pigs entering North America could probably focus the search for the unsampled pig population.

进入北美生猪的检疫和贸易记录也许可以聚焦在搜索未取样猪上。

Parameter values at the unsampled points in the well are calculated using the Artificial Neural Networks . This can improve the precision and provide more reliable information than other methods such as regression.

利用神经网络技术对井筒未取样点的储层参数进行了求解，提高了未取样点储层参数值的计算精度，为储层非均质性的分形地质统计学研究提供了较为可靠的基础资料。

Field survey, sampling and testing were used to discuss the characteristics of soil water content between different subsidence stages. The results show that after mining collapsing, the soil water content and soil water storage capacity of subsidence area is obviously less than the nature area, especially for the fissure zone. It is indicated that the collapsing fissures are extremely disadvantageous for soil water-holding capacity and the conditions of vegetational cover on the subsidence area also confirmed this result.

现以神府东胜煤田为研究背景，选择两个主要塌陷阶段分布区大柳塔矿区双沟村原农场和补连塔矿区原补连沟村作为研究区，采用野外勘查、取样测试与室内参数分析综合研究的方法，对采矿塌陷不同阶段表层包气带土壤水分进行对比分析，结果表明，采矿塌陷后，塌陷区尤其是塌陷裂缝区的土壤含水量与土壤储水量值均小于未塌陷区，说明塌陷裂缝对土壤的持水作用具有非常不利的影响，塌陷区与未塌陷区的地表植被覆盖情况也证实了这一点。

The pH, acetic acid, propanoic acid and VFAs were detected, in Selenomonas ruminantium culture fluid at Oh, 6h, 12 h, 24 h, 36 h, after adding yeast. The results indicated that lactate uptake can be stimulated by all of the six yeast strains at all of six concentrations levels.

实验设6个酵母组和一个未添加酵母的对照组，为了检测酵母的最适添加浓度和有效作用时间，将每一个酵母组均设6个浓度水平：2g／L，4g／L，6g／L，8g／L，10g／L，12g／L，并且在实验的0h、6h、12h、24h、36h分别取样，检测培养液的pH值和乙酸、丙酸等挥发性脂肪酸的含量。
