2283	经实验证明本文提出的方法能够提高短文本相似度计算的准确率。	Experimental results show that CDDCF per-forms better compared to baseline algorithms in term of its performance and efficiency of similarity computation.
2284	在实际数据收集中，不同敏感值的敏感度有很大差异，隐私保护需求也不相同。	In actual dada collection, the sensitivity of different sensitive information is different so that the concrete privacy need is different, too.
2285	然而，现有的基于随机响应的本地化隐私保护模型针对所有敏感值都执行同样程度的隐私保护，	However, the existing local privacy preservation model based on randomized response (RR), which is called conventional randomized response (CRR)for convenience, focuses on a universal approach that exerts the same amount of preservation for all sensitivity values, without catering for their concrete privacy needs.
2286	从而可能造成某些低敏感度的敏感值过度保护，而某些高敏感度的敏感值却保护不足。	As a result, it may be offering insufficient protection to a subset of people with relatively higher privacy needs, while applying excessive privacycontrol to another subset with relatively lower privacy needs.
2287	基于此，本文在常规随机响应(Conventional Randomized Response，CRR)模型的基础上，考虑个性化的隐私需求，引入敏感值权重，并将其引入到随机响应的决策中，提出一种面向多敏感值的个性化随机响应(Personalized Randomized Response，PRR)机制，该机制能够确保不同的敏感值群体均能达到各自期望的隐私保护程度，实现个性化的隐私保护。	Based on this, a new framework which is called personalized randomized response (PRR)is proposed based on the concept of CRR for multiple sensitive values-oriented personalized privacy preservation. The PRR technique considers personalized privacy needs, introduces sensitive value weights for differ-ent sensitive values, and then introduces the weights into the decision of RR for satisfying all sensitivity values'privacy needs, and thus, attains personalized privacy preservation.
2288	理论分析和仿真实验表明，在机制的主观隐私泄露程度一定时，相比于CRR 模型，本文所提的 PRR 机制统计估计误差更小，即获得的统计数据的质量更高，同时又保证了个性化的隐私保护。	Both theoretical derivation and simulation experiment reveal that the estimate error of statistics of PRR mechanism is smaller than that of the CRR mechanism for a certain subjective degree of privacy leakage, that is, the quality of statistics obtained by PRR mechanism is higher than that of the CRR model while guaranteeing personalized privacy protection for a given subjective degree privacy preservation.
2289	单相全桥逆变器处于硬开关状态时，随着开关频率的增大，开关损耗明显增大，影响逆变器效率的提高。	When a single-phase full-bridge inverter works in the hard-switching state, the switching loss will increasesignificantly with the increasing of switching frequency, so that it will affect the efficiency of the inverter.
2290	为解决这一问题，提出了一种节能型单相全桥谐振极逆变器，在逆变器处于死区状态时，将要开通的主开关并联的谐振电容的电压能减小至零，	In order to solve this problem, an energy-saving single-phase full-bridge resonant pole inverter is proposed. When the inverter is in the deadstate, the voltage across the resonant capacitor in parallel with the main switch can decrease to zero via the resonance of the auxiliary circuit.
2291	主开关动作时能完成零电压软切换，双向辅助开关动作时能完成零电流软切换。	The main switch can achieve zero-voltage switching, and the bidirectional auxiliary switch can realize zero-current switching.
2292	讨论了电路的工作流程，实验结果表明主开关和辅助开关完成了软切换动作。	The operation process of the circuit in a switching cycle is analyzed. The experimental results show that the main switch and auxiliary switch can realize soft-switching.
