  boundary age
     Based on the Jurassic/Cretaceous boundary age of 145.5±4.0 Ma published by the International Commission on Stratigraphy in 2004, combined with the genetic relationship between the Muchen intrusion and its adjacent Xishantou Formation volcanic rocks, it seems more reasonable to define the age of the Muchen intrusion at Early Cretaceous.
     根据2004年国际地层委员会公布的侏罗系与白垩系的分界年龄(145.5±4.0Ma),并结合沐尘岩体与旁侧西山头组火山岩的成因关系,沐尘岩体的形成时代确定为早白垩世早期似更合理。

AbstractEighty-four patients of severe pancreatitis weredivided by different line of age and the mortality of pa-tients with severe pancreatitis above and below the linewas comared.The results showed that the 60-vear ofage was the age with the lowest mortality.The analy-sis of 35 patients with severe pancreatitis who wereolder than 60 years of age indicated that multiple gall-stones was the most common cause iriitiating thedisease.The common severe concurrent diseases werebypertension, coronary disease,cerebrovasculardisease ,and respiratory disease. Common organ fail-ures were ARDS.shock and heart failure.The numberof failed organs in elderly patients in the fifth and sev-enth day after admission was obviously more than thatIn young patients.

作者将84例重型胰腺炎患者按不同分界年龄比较界上年龄和界下年龄患者死亡率的差异。结果发现60岁是影响死亡率的最低年龄分界线。通过对35例>60岁老年患分析显示,老年重型胰腺炎患者最常见的病因是胆囊多发结石;常见的严重伴随疾病为高血压、冠心病、脑血管病和呼吸系统疾病;最易发生衰竭的是呼吸系统和循环系统。以上结果提示,正确认识老年患者病理生理特点,积极治疗胆囊结石,加强呼吸、循环系统的保护措施,提高老年患者的抗病能力是防治老年重型胰腺炎的关键。

Objective To determine the dividing lines of every phase(slowed, accelerated, decelerated and stabilized) of stature growth according to the curvature variation of student stature curve.

Objective To determine the dividing lines of every phase(slowed, accelerated, decelerated and stabilized) of stature growth according to the curvature variation of student stature curve. Methods The initiative and terminate age of accelerated, decelerated and stabilized phases were defined by calculated curvature k (y) at each age stages of stature growth curve using a curvature equation. Results The initiative and terminate age of accelerated phase determined by curvature were similar to those by traditional methods. Conclusions Compared with traditional methods, curvature analysis is more convenient and valid method for studying features of student stature curve.

The variation in wood properties and the differences between juvenile wood and mature wood of Masson Pine( Pinus massoniana ) plantation from Guangxi were studied. The results are as follows: The boundary between juvenile and mature wood was delimited at the age of 14~16 year. The radial variation patterns of the anatomical properties from pith to bark are: the ratio of ray tissues, ratio of resin canal, cell walls percentage, lumen diameter, wall thickness of tracheid, tracheid diameter, tracheid length,...

The variation in wood properties and the differences between juvenile wood and mature wood of Masson Pine( Pinus massoniana ) plantation from Guangxi were studied. The results are as follows: The boundary between juvenile and mature wood was delimited at the age of 14~16 year. The radial variation patterns of the anatomical properties from pith to bark are: the ratio of ray tissues, ratio of resin canal, cell walls percentage, lumen diameter, wall thickness of tracheid, tracheid diameter, tracheid length, ratio of wall to lumen (latewood) increase with the increase of growth ring, while ratio of tracheid and ratio of lumen to diameter decrease with the increase of growth ring. Most parameters of the anatomical properties of mature wood are higher than that of the juvenile wood with significance level shown in ratio of resin canal, cell walls percentage, wall thickness of tracheid, tracheid diameter, tracheid length. All of the physical and mechanical properties of mature wood are higher than that of juvenile wood significantly. Analysis of relationship showed that the ratio of ray tissues, ratio of resin canal, rate of cell wall, tracheid length were positively correlated to wood density with significance level. The MOR, MOE, and crushing strength were positively correlated to wood density significantly in juvenile and mature wood.

本文研究了广西人工林马尾松木材性质的变异及幼龄材与成熟材的差异。结果表明 ,幼龄材与成熟材的分界年龄在 14  16a ,解剖性质在径向上的变异规律为 :射线比量、树脂道比量、胞壁率、胞腔直径、胞壁厚、管胞长度、管胞宽度和晚材壁腔比是自髓心向外呈递增趋势 ,管胞比量和晚材率为递减趋势 ,早材壁腔比和早材腔径比则近似于一条直线。方差分析结果表明 :树脂道比量、胞壁率、胞壁厚、管胞长度和管胞宽度 ,幼龄材与成熟材差异达显著或极显著水平。 5项木材物理力学性质均为成熟材高于幼龄材 ,且均达差异显著水平。木材性质间的相关分析表明 :木材基本密度与管胞长度、管胞宽度、射线比量、树脂道比量、胞壁率呈显著的正相关关系 ,木材气干密度与抗弯强度、抗弯弹性模量、顺纹抗压强度也呈显著的正相关关系
