Freezing soil is a natural phenomina in cold and mountain areas, which has great impact on the regional climate, water cycle, and water balance. The land surface process in the condition of soil freezing and thawing is one of the most important process in the area. This paper firstly reviews the present study on land surface process in the condition of soil freezing and thawing, especially the development after the the hydrological land surface model introduced into the study of General Circulation Model, then introduces the undergoing international research project, such as Project for Intercomparison of Land-surface Parameterization Schemes and Cold Land Process Field Experiment by NASA, and finally analyses and puts forward the future research field and topics.

Results In 7 cases of odontoid process fracture, X-ray demonstrated 4 cases and CT demonstrated 5 cases, whereas the spiral CT reconstruction diagnosed 7 cases, which could display the displacement of fracture clearly. The X-ray and CT showed asymmetric space between left and right gaps of atlantoaxial joint in 6 cases, while spiral CT reconstruction showed normal and excluded the possibility of atlantoaxial dislocation. There was one case of lateral atlantoaxial joint dislocation, which was demonstrated by the spiral CT reconstruction clearly but not by the X-ray and CT scan. There were 3 cases of atlantoaxial congenital deformity (1 case of absence of both posterior arch of atlas and odontoid process and 2 cases of maldevelopment of the odontoid process), which were displayed clearly by spiral CT reconstruction, but misdiagnosed as odontoid process fracture and atlantoaxial subluxation by X-ray and CT scan.

结果 7例齿状突骨折中，X线显示4例，CT显示5例，CT重建确诊7例，且清楚显示骨折移位情况；6例X线、CT显示寰枢椎左右间隙不对称，通过CT重建排除寰枢关节半脱位；寰枢外侧关节脱位1例，CT重建可清楚显示，而X线片和CT平扫均未能显示；寰枢椎畸形3例，分别为齿状突、后弓缺如1例，齿状突发育不良2例，CT重建均能清楚显示，而X线、CT均误诊为齿状突骨折、寰枢椎半脱位。

Displaces is simultaneously pays great attention to the goal and the process, and the teaching process mutual conformity interaction, the multiplication, the dynamic process evaluation. By science of library classification this article straightens out the foundation (Contend analysis, Post-modernism, Multi-intelligence), connotation and evaluation tools (students card, growth portfolio, academic performance on biological learning) of the process evaluation.

取而代之的是同时注重目标与过程、与教学过程相互整合的互动化、多元化、动态化的过程性评价本文通过文献法理清了过程性评价的理论基础(建构主义、后现代主义、多元智能论)、内涵及所需的主要评价工具(学生生物学科日常学习记录卡、生物学科学生成长袋、生物学科学生成绩记录册)。

PCA is not only used as feature extracting method (where process variables are subjected to multivariate normal distribution), but also as a tool for dimension reduction; BSA is used to extract independent features or process blind source signals from process information in information theory sense, which is more effective than PCA in describing the process.

主元分析方法不仅作为一种过程特征的提取方法（在过程信息服从多元正态分布的情况下），而且也作为一种过程数据降维的主要工具（在过程盲源信号提取的情况下）；盲源信号分析是从信息论的角度，从过程信息中提取出尽可能独立的过程特征信号或过程原始信源信号，它具有比主元分析更好的刻画过程运行特征的性能。

Since batch operation of MRCRS can be applied easily and extensively in production process, a kind of non steady—state microbial reaction coupled with a complete cell recycle separation process is emphasized and analyzed. This dynamic process was characterized by which cells were retained completely by the recycle separation process without purge stream.

五 鉴于微生物反应一循环分离耦合过程的间歇操作在生产过程中极易使用，本文还分析了分离过程对细胞完全截留且没有任何洗脱流存在的非定态的微生物反应一完全细胞循环分离耦合过程的操作特性及其优化。
