When the cpa carries out any intentional or gross negligent conduct on this condition , he will assume joint liability with the principals and the third parties ; otherwise he will assume divisional responsibility 这时如果注册会计师再出现故意或重大过失,委托人或第三人应与注册会计师承担连带责任;而注册会计师仅只是一般过失时,其与委托人或第三人承担按份责任。
On this condition , we design two data collection modules and a communications module . at last , we can use a computer as a net control platform , which was connected on the net , we call the whole system anynet - 3 在此基础上，我们设计了用于数据采集的节点模块以及用于网络通信的控制模块，利用网络中的一台计算机作为上位机构成了我们所设计和开发的一种网络控制系统? ? anynet - 3 。
On this condition , the paper gives the detailed design and implementation of an editor for courseware description language ; moreover , gives some important data structures and algorithms used during development . some of the methods are very practical 在此基础上，本文讨论了一个具体的针对课件描述语言的编辑器的设计开发以及实现过程，并对开发过程中重要的数据结构以及算法进行了描述。
This thesis is based on this condition . in the view of emotion , the investigation of the mental health state of impoverished undergraduates shows that there is significant difference between the mental health state of impoverished group and that of non - impoverished group 本文正立足于此，从情感的角度上对贫困生心理状况进行了调查，发现高校贫困生的负性情感状况与非贫困生的相比呈显著差异。
A lower voltage power line carrier communication system on spread spectrum technology based on this condition is designed , which is composed of a singlechip computer at89c51 and pl2101b . this article described the hardware and software of the system , and the field - test showed the system is feasible 在此基础上，开发了基于扩频技术的低压电力线载波通信系统，系统主要由at89c51和扩频通信芯片pl2101b组成，完成了该系统的硬件设计、制作，软件的编程和调试。
In part two , the focus is on the stabilizability and detectablity of 2 - d singular systems . necessary and sufficient conditions for stabilizability and detectablity of 2 - d singular systems are obtained respectively , and the relationship between bibo stability and internal stability is discussed based on this conditions . the observer design procedures are also provided 在能稳性和能检测性部分，用频域研究方法，分别给出了2 - d奇异系统能稳、能检测的两个等价条件，一个是能稳、能检测的秩判别条件，另一个为bezout恒等式存在稳定的有理函数矩阵解。
The effect of deposited condition , include substrate temperatures , different substrates and annealing on the structural properties of zno films has been studied in considerable detail . it is found that the optimal conditions to deposit zno are below : the substrate temperature of 450c , the substrate of sapphire . the sample on this condition is 0 . 3491 通过分析衬底温度、不同衬底和退火对样品结构的影响，得到了样品的最佳制备条件：衬底温度450 、蓝宝石衬底，此条件下制备的样品具有高度( 002 )取向性， ( 002 )衍射峰半高宽仅仅0 . 3491 ，原子力显微镜( afm )分析表明zno薄膜具有密集堆积的均匀柱状晶粒。
The efficiency and reliability of minerogenetic prediction can be improved by combining rs with gis . we processed rs images , extracted the geological information related to mineralizing , such as geology , structures , stratam , rocks , etc , synthetically analysed remote sensing , the geological data and geo - chemistry , under the guidance of the theory and mathematic model , set up gis mineralize model . on this condition , to develop this method and its theory , and to establish a system of perfect prediction , it is not only useful in studied degree area but also favorable for looking for new type and some form large - scale deposits in old studied area , and it has a great theoretical meaning 遥感与gis相结合用于成矿预测中可大大提高预测工作的效率和可靠性。通过对研究区的遥感图像处理和地质、构造、地层、岩石、矿化蚀变等有关信息的特征提取、遥感、地质数据和物化探数据的综合与复合分析，在一定成矿理论和数学模型指导下，建立gis综合找矿模型。在此基础上，发展这一方法及理论并建立完善的预测体系，不仅对研究程度较低的新区矿床预测有用，而且对研究程度较高的老区寻找新类型和点状大型、超大型矿床都具有重要理论意义和实际意义。
