2004年3~6月，在黑龙江省三江国家级自然保护区海青保护站马圈岛，采用随机抽样法，对随机选取的50个普通鸬鹚巢逐一进行编号和测量，进行巢材、巢位和巢大小等的研究；采用总面积调查法(样方大小为30m×30m)，对普通鸬鹚巢的分布格局、分布特点进行了研究。

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。

One mixed-ligand complex ofnH2Otpa=terephthalate, tripy=4'-(4methyoxyphenyl-2,2':6',2-terpyridine was synthesized and characterized by IR, elemental analysis and thermo-gravimetric analysis. The crystal structure of the product was established by single-crystal X-ray diffraction.

Based on the evaluation of rock mechanics properties of undrilling formation, a fuzzy optimization model for selecting the best similar layers with the same rock mechanics properties was established by applying theory of fuzzy optimization. Firstly the best similar layer located the undrilled area was chosen by the model. Secondly the performance of the bit used in the selected layer was evaluated by economic benefit index.

Monopdization of tobacco gleans the State monopolizes tobacco transaction by making the law t0guarantee the financial income The Law of Tobacco Monopolization and The Law of Price are ordinary laws It is not reasonable to make the prices of tobaccos be regulated by market on the ground that special laws are prior to ordinaty laws and subsequentlymade laws are prior to the previouslymade laws This issue also involves the scope of authority of the legal interpretation,and the effectiveness of the legal interpretation,which needs to be closely studies and considered.

烟草专卖是国家通过制定法律，对烟草买卖实行垄断，以保证财政收入。《烟草专卖法》和《价格法》是同一位阶的普通法，以特别法优于普通法、后法优于前法的理由，主张将烟草价格推向市场，是不能成立的。这一问题还涉及法律解释的权限、法律解释的效力问题，亟需认真研究和对待。

Good news for Farmar and the Lakers: He's looked just as explosive in the 2009-10 preseason as he did early last season, when his ability to push tempo off the bench was a key element to L.A.'s 20-3 start. However, a few games later, Farmar tore the lateral meniscus in his left knee and missed 17 games. Although getting back into rhythm was difficult for the backup point guard out of UCLA, his biggest contribution of the season came when Derek Fisher was suspended for Game 3 of the Western Conference Semis and Farmar contributed 12 points, seven assists, five rebounds and two steals with just one turnover in 33 minutes of L.A.'s 108-94 win.

法玛尔和湖人的好消息：在2009-10的季前赛他看起来好像大爆发一样，就像他上赛季做的一样，当他的能力在替补席上爆发出来的时候，他成为了湖人取得20胜3负开局的关键，在打完了一些比赛之后，法玛尔膝盖半月板韧带拉伤，他错过了休息了17场比赛，尽管随后他重回球馆，但是看起来他似乎对比赛还很困难，这位 UCLA 的组织后卫，对球队最大的一次贡献，是在西部半决赛第三场，当费舍尔被禁赛的时候，他顶替了费舍尔首发，在33分钟的上场时间里贡献了12分，7次助攻，5个篮板和2次抢断，帮助球队108-94赢下了比赛。
