P. denasta harbored the three chlorotypes, two of which were characteristic of its two parental species respectively. The third chlorotype was extensively distributed in seven of the ten P. densata populations analyzed, and might represent a mutation type or have been derived from an extinct parent.

TT和GC分别是油松和云南松种特异性叶绿体单倍型，而在高山松群体里则三种单倍型均有分布，而且TC单倍型广泛地分布在7个杂种群体中，该单倍型很可能来源于点突变或第三个已灭绝的亲本。rbcL基因检测到的高山松群体分化系数很高（G〓=0.533）。

In the third chapter, at first the significance and basic idea of the phase space reconstruction is discussed.

第三章首先讨论了相空间重构的意义及基本思想，给出分形维的概念及分形维的计算方法，分析了关联维数的相关问题。

The first one is to generate the circle for each borderline segment of the component by considering the segment length and the prescribed tolerance value. If this is not the case, the borderline segment will be equally divided into halves until the obtained circle satisfies the tolerance value over the whole borderlines of the component. The basic idea of the last two algorithms aims at covering the domain occupied by the component as much as possible. The circle generation is carried out sequentially from salient angle to the sector formed by the salient angle till the uncovered borderline segments of the component. Particularly, the three-step algorithm with gap allows that the generated circles are distributed with gap along the component contour.

二分法利用组件各边长度和设置的容差大小得到该边的候选包络圆，若该圆不满足组件所有边的容差要求，则将该边不断地对分，直至所得到的包络圆满足各边的容差要求；三步划分法和带间隙的改进三步划分法则以组件区域为划分对象，依次对组件多边形凸顶角、凸扇形区和多边形各边剩余线段划分包络圆，且带间隙的改进三步划分法则允许包络圆在组件边界上以适当的间隙分布。

We report a sponge spicule assemblage from the Lower Cambrian black shales of the Hetang Formation at Xiuning in Anhui Province, South China. Based on morphological differences, the spicules can be divided into 4 types including monaxons, biaxons, triaxons and tetraxons.

本文报道皖南休宁县早寒武世荷塘组黑色页岩中产出的海绵骨针化石组合，这些海绵骨针化石具有较高的丰度和分异度，它们以二轴四射针、T型针、三轴六射针和三轴五射针为主。

In the first part, the opinions and ideas from some main figures concerning the North-western regions in modern history; In the second part, the process of three vital stages(Yang-Wu Movement, the "New Deal" in the last period of Qing Dynasty, Anti-Japanese War) are studied, and the characteristics of each stage are generalized falling into four categories, such as: military、feudal、comprador and nation-monopoly etc; In the third part, four reasons of the low efficiency of the industrial and mineral exploration are explored, they are the dominant role natural economy, the low level of productive forces, the science and technology, lack of capital accumulation and investment, lack of systematic policies and support from the government, In a word, as Mao Tsetung said:"It"s impossible to get rich, develop industry, strengthen national defence in semi-colonel and semi-feudal China.

全文共分四部分，第一部分论述了近代一些主要的阶级关注西北的言论和思想；第二部分对西北近代工矿业开发的三个最重要的阶段，即洋务运动时期、清末"新政"时期、抗日战争时期的开发过程做了梳理，并对每一个阶段的特点做了初步地概括，大致可以归纳为军事性、封建性、买办性以及国家垄断性等；第三部分对西北近代工矿业开发成效不高的原因做了论述，主要有四点：第一，小农业与家庭手工业紧密结合的自然经济占统治地位；第二，生产力水平低下，科学技术落后；第三，缺乏资金的积累和投入；第四，缺乏政府系统的政策支持和保障。

The headache index, or sum of the 3 daily severity scores, was graphed during each day of the 3 menstrual cycles, and "peaks" of headache severity scores were identified, the authors write.

作者指出，之后纪录三次排卵期每天的头痛指标、或是以三次每日严重度分作图，且确认"最高"头痛严重度分数；如果头痛指数的最大值出现在这段时间，则该头痛最大值与特定时间有关。

He'd pulled a couple of bottles of beer from the refrigerator when we left the kitchen, and we were seated across from each other at either side of the long trestle table that was his desk out there and that was stacked at one end with composition books, some twenty or thirty of them, divided into three

在我们离开厨房时，他已从冰箱里拿出几瓶啤酒，我们分坐在他当书桌用的长条桌两边，桌子的一头堆放著作文簿，大约有二三十本，分成三摞。

The Yankees, however, had taken advantage of three Seattle errors and staked Wang to a 3-0 lead after two. Seattle's Erik Bedard was unhittable after that, and retired the final 14 batters he faced, but with Wang on the mound — and Kyle Farnsworth, Chamberlain and Mariano Rivera after him — the Yankees didn't need the two insurance runs they got in the eighth.

反观洋基，在前两局就趁著水手的三次失误打下3-0给小民当本钱，此后水手的Erik Bedard就不再挨打，接连解决14名打者，但是这可是王小民在投球，后头的方师傅，张伯伦，李维拉也不赖，洋基根本不需要八局多打下的两分保险分。

Bonderman (10-7) allowed seven runs and eight hits in 5 2/3 innings, walking four and striking out none. He surrendered a two-run double up the left-center-field gap to Hideki Matsui in the first inning, one of three hits for Matsui, who has hit safely in 44 of 48 games and appears to be taking to the designated hitter spot -- sporadic as it may be -- with aplomb.

T； X1 F9 D1 h$ N王建民加油站棒得慢(10胜7负)在5又2/3局投球中丢了7分，保送4次，没有三振，他在第一局就被马猪蚁打出一支两分打点的左外野二垒安打，这是马猪蚁这场比赛3支安打中的1支，他在48场比赛中有44场击出安打，显示出他已经可以沉著地适应指定打击的工作(偶尔需要他担任指定打击的时候)。
