碳捕获和地质储存是抑制大气中CO2含量增加的潜在途径。了解断层的作用，无论是作为CO2流动的障碍体还是通道，都是预测长期地质储存场地完整性的关键。特别值得关注的是地球化学反应对断层密封性的影响和地震活动及应力状态对断层稳定性的影响。本文研究了CO2从犹他州一个断裂的天然CO2气藏渗漏135000年的古记录，测定了由富CO2流体沉淀形成的碳酸盐岩脉的U—Th年龄及其同位素和微量元素的组成。该岩脉地球化学特征随时间的变化表明，CO2从更深的地层脉冲式注入到储集层。这些气体脉冲式注入之后，CO2地面渗漏率增加几个数量级。我们说明，每次脉冲式注入发生在冰期向间冰期过渡期，当地气候开始变暖之后100～2000年。CO2渗漏率增大是断裂开放的结果，断裂开放可归因于水文地质状况的变化、游离气顶的间歇性存在或者断裂附近地区地壳后冰川期的卸载作用。

目的：评价并比较在填入复合树脂前对粘结剂进行光固化和粘结剂与复合树脂同步固化两种情况下．3种自酸蚀粘结剂与牙釉质和牙本质的剪切粘结强度。材料和方法：对120颗拔除的牙齿进行湿磨以在牙釉质和牙本质上形成粘结平面。按照厂家操作说明分别将3种粘结剂（Adper Prompt—*** SE Bond和Xenolll）涂于牙釉质或牙本质上。半数样本涂布粘结剂后＆口刻光固化（PRC组），另一半将复合树脂填入后再行光固化（COC组）。将复合树脂置入特氟龙管内并在其上方进行光固化。样本于室温储于去离子水中24h后．使用拉伸强度试验机进行剪切力加载直到断裂。用2因素方差分析、预固化和材料的单因素分析、以及Tukey显著性检验多重比较程序来分析剪切粘结强度（MPa）。所有检验均在5％显著性水平（n=10）进行。结果：与同步固化方法比较，先光固化粘结剂的方法显示其与牙本质的粘结强度明显增高（P〈0001）：而与牙釉质的粘结强度．PRC组与COC组并无显著差异（P=0．420）。结论：在固化复合树脂之前．对自酸蚀粘结剂预固化可产生更大的牙本质粘结强度：不同的自酸蚀粘结剂固化技术对釉质的粘结强度并无明显影响。

The chapman-Richards Distribution and its Relationship to the Generalized Beta

引用

Forest Ecosystems 2019年第3期6卷 219-235页

作者： jeffrey H.Gove Thomas B.Lynch Mark j.Ducey USDA Forest Service Northern Research Station271 Mast Road Durham 03824NHUSA Professor Emeritus Department of Natural Resource Ecology and ManagementOklahoma State UniversityAg Hall Room 008CStillwater 74078OKUSA Department of Natural Resources and the Environment University of New Hampshire114 James Hall Durham 03824NHUSA

Background: The chapman-Richards distribution is developed as a special case of the equilibrium solution to the McKendrick-Von Foerster equation. The chapman-Richards distribution incorporates the vital rate assumptions of the chapman-Richards growth function, constant mortality and recruitment into the mathematical form of the distribution. Therefore, unlike 'assumed' distribution models, it is intrinsically linked with the underlying vital rates for the forest area under consideration. Methods: It is shown that the chapman-Richards distribution can be recast as a subset of the generalized beta distribution of the first kind, a rich family of assumed probability distribution models with known properties. These known properties for the generalized beta are then immediately available for the chapman-Richards distribution, such as the form of the compatible basal area-size distribution. A simple two-stage procedure is proposed for the estimation of the model parameters and simulation experiments are conducted to validate the procedure for four different possible distribution shapes. Results: The simulations explore the efficacy of the two-stage estimation procedure;these cover the estimation of the growth equation and mortality-recruitment derives from the equilibrium assumption. The parameter estimates are shown to depend on both the sample size and the amount of noise imparted to the synthetic measurements. The results vary somewhat by distribution shape, with the smaller, noisier samples providing less reliable estimates of the vital rates and final distribution forms. Conclusions: The chapman-Richards distribution in its original form, or recast as a generalized beta form, presents a potentially useful model integrating vital rates and stand diameters into a flexible family of resultant distributions shapes. The data requirements are modest, and parameter estimation is straightforward provided the minimal recommended sample sizes are obtained.

多花黑麦草（Lolium mulitiilorum Lam.）×高羊茅（Festuca arundinacea Schreb.）的杂种分离后代用于培育Gl—307品系,该品系含有较低的佩洛灵（Perloline）生物碱,并有良好的多汁性和可消化性。牲畜在高温条件下采食Gl—307时会患"夏季综合症"病。Epichloё typhina病是一种内寄生菌病,该病的发生与Gl—307中N—乙醯基和N—甲酸基吡咯兹啶生物碱的出现有关。吡咯兹啶生物碱的出现又和夏季综合症的条件相关。我们的目的是研究佩洛灵,N—乙醯基和N—甲酸基吡咯兹啶生物碱性状的遗传力和变异性,以及和***病的联系。Gl—307的28个亲本无性系为了降低佩洛灵的含量和改良多汁性与可消化性,进行了二轮的轮回选择,并在二个分别隔离的多系天然杂抗区内种植,一个隔离区的无性系是不处理的,而第二个隔离区的无性系用一种杀菌剂苯菌灵（benomyl）处理,以除去***病。不处理的无性系多系天然杂交后代,Gl—30 7品系,和各个商业品种在随机排列的各个重复小区都测定了佩洛灵的含量。处理和不处理隔离区的每个无性系等量种子混合而成Gl—307品系。经处理的Gl—307和不处理的Gl—307的种子分别用于建立2.2和2.3公顷的草地。在佩洛灵,N—乙醯基和N—甲酸基吡咯兹啶生物碱的含量上,不处理的亲本无性系和多系天然杂交后代的平均量显然不同。用佩洛灵,N—乙醯基和N—甲酸基吡咯兹含量的亲本变量来测定广义遗传力,其结果分别为0.88,0.67,和0.76。用多系天然杂交后代的方差测得的广义遗传力分别为0.50,0.33和0.79。佩洛灵的N—L醯基和N—甲酸基吡咯兹啶含量的狭义遗传力测定结果分别为0.45,0.51和0.91。当亲本无性系用benomyl处理时,由于减少了***病的感染,因而吡咯兹啶生物碱的含量分别减少了71.5%和67.9%,用benomyl处理过的种子和不处理的无性系而建立的草地的干草,其吡咯兹啶生物碱含量水平分别为115和875微克/克,***病的感染率分别为44%和95%。
