Along with the development of diagnosis and treatment technology , as well as the application of ultrasound - guided percutaneous needle aspiration and catheter drainage widely , the prognosis of bacterial liver abscess has been improved 摘要随着诊疗技术的进步和超声引导穿刺的广泛应用，细菌性肝脓肿的预后有了明显的改善。
Independent feeding tray : learning from the foreign advanced technology , we discarded the central feeding or side feeding method , and applied the independent tray making materials fed more evenly with automatic control 独立式斜盘布料装置：借鉴国外先进技术，一改过去传统的中间布料或侧向布料方式，加料的均匀性和可操作性得到了明显的改善，并可与电控系统实现连接，实现自动化控制。
It can be seen from the experiment results that field emission performance of pure diamond is not very good . after eptitaxy and silver coating , its field emission performance can be well improved . it is expecting to realize low - voltage electron and high current density field emission 从实验数据上看,电泳金刚石的场发射效果不十分理想,但经过外延生长和包银处理后,场发射特性得到了明显的改善,这说明金刚石表面修饰对金刚石场发射有重要意义。
This thesis begins with research on basic theroies of speech processing , especially emphasizes on the speech recognition algorithms , noise estimation and speech enhancement techniques , and applies speech enhancement techniques to speech recognition system in noisy environment . experiments show that the performance of system has been improved obviously 本文从研究语音处理的一些基本理论入手,重点研究了其中的语音识别算法、噪声参数估计方法和语音增强技术,并将语音增强技术应用于低信噪比噪声环境下的语音识别系统中,实验结果表明,系统性能得到了明显的改善。
“ the whole nation from top to bottom is mobilising and results are gradually becoming apparent in energy conservation and emission reductions , ” said xie zhenhua , vice - chairman of china ' s national development and reform commission . “ however , the situation remains extremely bleak , with some work not being properly done , ” mr xie said , citing problems with energy intensity and pollution statistics 在谈到能源紧缺与环境污染问题时，国家发改委副主席谢振华说道：现在全国上下都在积极参与节约能源与减少污染物的排放，并且已经取得了明显的改善，然而，由于一些工作还没有做到位，整个形式仍然不容乐观.比如能源强度和污染情况的数字统计
The advantage of multistage support vector machine is embodied in three aspects . first , towards the unpredicted areas of other multiclass support vector machines , multistage support vector machine can predict them more correctly ; secondly , according to the experimental comparison , the dissertation shows us the high accuracy of its evaluate performance . finally , for a multiclass classification , multistage support vector machine need less support vectors to construct multistage hyperplane than the other three methods , so the multistage support vector has the better generalization 多级支持向量机的优点主要体现在三个方面：一方面，对于其他几种多类支持向量机不能处理的不可测区域，它有了明显的改善；另一方面，本文通过实验比较，指出了多级支持向量机测试准确率高的特点；最后，对于一个多类问题，多级支持向量机在构造多级超平面时需要的支持向量明显少于其余三种多类支持向量机，因此具有更强的泛化能力。
This article appraised the sustainable development ability of the rcc , although from 2003 , the economic indicator of the rural credit cooperatives had distinct improvement , generally speaking , its management condition still displayed the low self - development ability and the relative high rural finance permeability , it is hard to meet the needs of the rural economy 本文从评价我国农村信用社可持续发展能力出发,指出虽然2003年以来,农村信用社各项经济指标有了明显的改善,具备了相对较高的农村金融渗透程度。但总的来说,其经营状况仍不容乐观,自我发展能力还比较低,难以满足农村经济持续发展的客观需要。
