郯庐断裂系统与中国东部幔源岩浆成因CO_2关系的初探

中国已发现的幔源岩浆成因CO2气藏主要分布在与郯庐断裂发育密切相关的东部伸展盆地，两者关系具体表现如下：1．中国东部幔源岩浆成因CO2气藏的空间展布与郯庐断裂保持一致；2．郯庐断裂切割深度达到上地幔；3．沿郯庐断裂岩浆活动强烈，且具幔源特点；4．中国东部伸展盆地自中、新生代以来的演化受郯庐断裂带活动影响。本文主要以郯庐断裂带为主线，结合幔源岩浆成因CO2气藏典型实例，从郯庐断裂构造环境、空间格局和演化过程对幔源岩浆成因CO2的控制作用进行初步归纳和分析。

二氧化氯预氧化工艺处理微污染黄河水研究

对二氧化氯预氧化工艺替代预加氯系统处理低温、含异味和较高色度的黄河原水进行了综合研究。与预氯化、混凝沉淀系统相比，二氧化氯预氧化、混凝沉淀系统对藻类的去除率提高了30％～40％，使嗅和味的阚值降低了10～20，但CODmn和氨氮的去除率的变化不明显。由于进水色度变化较大，对色度的去除率变化也不明显。运行证明，该系统改造后对降低以微污染黄河水为水源的北方给水处理厂冬季运行过程中的出水嗅和味的阚值、增加藻类的去除率具有明显的效果，同时，运行费用也较低。     

测空气中SO2时的主要影响因素

目前测定空气中SO2主要采用甲醛吸收-副玫瑰苯胺分光光度法。该法操作比较严格，测试结果的准确度受诸多因素的影响。因此文中对这些影响因素进行了探讨，主要为试剂质量、显色温度和显色时间、溶液加入顺序、比色皿、空气采样器流量、采样温度、导气管的吸附等因素对测定结果的影响进行了探讨。     

Carbon Dioxide Balance of Wood Substitution: Comparing Concrete- and Wood-Framed Buildings

In this study a method is suggested to compare the net carbon dioxide (CO₂) emission from the construction of concrete- and wood-framed buildings. The method is then applied to two buildings in Sweden and Finland constructed with wood frames, compared with functionally equivalent buildings constructed with concrete frames. Carbon accounting includes: emissions due to fossil fuel use in the production of building materials; the replacement of fossil fuels by biomass residues from logging, wood processing, construction and demolition; carbon stock changes in forests and buildings; and cement process reactions. The results show that wood-framed construction requires less energy, and emits less CO₂ to the atmosphere, than concrete-framed construction. The lifecycle emission difference between the wood- and concrete-framed buildings ranges from 30 to 130 kg C per m² of floor area. Hence, a net reduction of CO₂ emission can be obtained by increasing the proportion of wood-based building materials, relative to concrete materials. The benefits would be greatest if the biomass residues resulting from the production of the wood building materials were fully used in energy supply systems. The carbon mitigation efficiency, expressed in terms of biomass used per unit of reduced carbon emission, is considerably better if the wood is used to replace concrete building material than if the wood is used directly as biofuel.

Framing the Long-Term <Emphasis Type="Italic">In Situ</Emphasis> Liability Issue for Geologic Carbon Storage in the United States

This paper examines how legal standards of liability may apply to geologic carbon storage. The liability regime governing geologic carbon storage will shape the technology's cost-effectiveness and overall attractiveness. We classify potential sources of liability into operational, in situ, and climate liability. As a first step, we explore in situ liability in the United States. After summarizing legal standards of liability including negligence, breach of implied warranty, strict liability, and product liability, we discuss how liability may be addressed at the level of the federal government, state government, industry, and the firm. Finally, we address the implications of judicial treatment of liability for carbon storage, including the apportionment of liability and the adequacy of current regulations.
