国外测绘 1994年第5期 4-9页

作者： licht.,H 王爱朝

周跳探测是ＧＰＳ数据处理的重要课题。根据所得数据的类型，例如码伪距和相位伪距等，已有多种方法。总的说来，每种方法都各有其优缺点。本文提出两步探测法，用来探测周跳，在建立起检验量后，从平滑角度对其探测功能进行，检定，一... 详细信息

基于测距码的ＧＰＳ动态测量对于实于差分定位的精度为米级。对于铁路工程的许多任务来说，这样的精度足以满足需要，可是，考虑到诸如铁路轨道的养护和维修，必须要有亚厘米级的精度，就ＧＰＳ来说，这要求作载波相位测量，为了进行实时解算，必须从一个沿着路轨流的接收机到主站接收机通过无线电联系来传输数据，由于地形和工程结构上的原因，实际上常会产生信号失锁问题，于是就需要有一种方法来确定过程中的整数模糊度。

Kinetic Characterization of Trichoderma reesei CL847 TR3002： an Engineered Strain Producing Highly Improved Cellulolytic Cocktail

＜正＞Project planning methods and tools still have weaknesses when it comes to modeling weakly structured work processes, task interdependencies or uncertainty. Particularly when managing parallel product development projects it is challenging to plan task assignments to personnel, to predict the resulting work load, the temporal course of work progress and to model these issues in a consistent framework, a rather unrealistic project scheduling often occurs which has not much in common with the real course of work progress. It is a well known fact that important tasks may then be neglected for the benefit of urgent tasks - leading to an operational precipitance at the end of the project. Exceeded deadlines or development results of poor quality are common consequences. Existing simulation approaches only theoretically provide some help here. Due to laborious definition of predecessor-relations of tasks, even if tasks are practically performed in parallel, an effective practical deployment has not taken place yet. In this paper a person-centered, actor-driven simulation approach is proposed that can cope with highly parallel tasks. The task execution sequence is determined by means of a bounded rational choice model. The unfolding model behavior is very realistic and can therefore provide a good basis for predicting project duration and costs. Test statistical results from a case study show that the simulated project duration differs not significantly from the empirically observed proj ect duration.

Enzymatic hydrolysis of lignocellulose is often considered to be the major economic bottleneck of the production process of bioethanol from lignocellulose. It is generally admitted that the most efficient organism for the production ofcellulolytic enzymes is the fungus Trichoderma reesei, mostly due to its high secretion capacity. Unfortunately, this fungus secretes very low concentrations of β-glucosidase, thereby often requiring β-glucosidase supplementation for complete cellulose hydrolysis. It is especially important to have sufficient quantities of β-glucosidase in order to prevent inhibition of cellobiohydrolases by cellobiose. In order to optimize the produced cocktail, a more efficient β-glucosidase was cloned into T. reesei CL847 strain. The new strain, called CL847 TR3002, secretes the evolved β-glucosidase and was tested for cellulase production in laboratory-scale reactors. Its growth kinetics and cellulase production were characterized using fed-batch and chemostat modes under various culture conditions. The cellulase activities of the evolved strain were compared with activities of the parent strain. In addition, hydrolysis of a steam exploded wheat straw was performed at three different enzyme-loading levels （5 mg/g, 10 mg/g and 20 mg/g of dry matter） and a new kinetic model was developed.

前言由于近几年来形形色色结构与机器设计的进展,相应出现了更多的振动问题。精确测量冲击与振动的必要性变得十分重要。因此,为优选振动传感器的结构与规定其校准方法付出了很大的努力。本文着重论述压电加速度计的动态校准方法。压电加速度计已很普及,因为它对质量比的灵敏度高而对不利环境的灵敏度低。压电加速计的频率范围与动态范围很宽,适合于当前先进的测量与分析设备的性能。校准一般是指用于检验可能影响传感器测量精度的全部工作特性的过程。
