The simulation results show that XPM induces the distortion of waveforms and the leak of side lobes. And the larger the modulation bandwidth is, the larger the leak of side lobes is. Furthermore, the power transmission function of NOLM T is distorted because of the XPM-induced nonreciprocity： Tm decreases when the splitting ratio of the coupler f∈（0,0.5） and increases when f∈（0.5,1.0）.展开更多

Since the founding of the People Republic of China, China has carried out the codification of civil code for four times, and since the part^s eighteen plenary session officially proposed the ＇codification of civil code＇, the issue of the civil and conmaercial relation draws the attention again, either unification or division of civil and commercial law directly affects the system and content of the civil code, and affects how to process the relationship between the civil law and commercial law during the codification of the civil code as well. The codification of the civil code should not only consider the legislative tradition of the civil and commercial legislation and the current legal system, but also pursue characteristics of the commercial law, in a system of combining civil and commercial law, through adding commercial law into the general principle of civil law; the existing commercial law should be separately retained.展开更多

It is shown that hexahedral mesh scheme is more suitable for the complex structure of the flotation cell than tetrahedral mesh scheme, and a mesh quality ranging from 0.7 to 1.0 is obtained. Comparative studies of the standard k-ε, k-ω and realizable k-ε turbulence models were carried out. It is indicated that the standard k-ε turbulence model could give a result relatively close to the practice and the liquid phase flow field is well characterized. In addition, two obvious recirculation zones are formed in the mixing zones, and the pressure on the rotor and stator is well characterized. Furthermore, the simulation results using improved standard k-ε turbulence model show that surface tension coefficient of 0.072, drag model of Grace and coefficient of 4, and lift coefficient of 0.001 can be achieved. The research results suggest that gas-fluid two-phase flow in large flotation cell can be well simulated using computational fluid dynamics method.展开更多

Linkage ratios were measured by high performance liquid chromatography. The derivatives＇ antifungal activity against the plant pathogenic fimgi Rhizoctonia solani CGMCC 3.28 and Gibberella zeae CGMCC 3.42 were investigated at concentrations of 100, 200, and 400 mg/L. These HML-CS derivatives exhibited stronger antifungal activity than CS alone. HML-CS-1 showed the best antifizngal activity against G. zeae, whose antifimgal index was 65.9% at 400 mg/L, and also showed the best antifungal activity against R. solani, whose antifimgal index was 52.7% at 400 mg/L. This conjugation of CS and HML suggested the presence of synergistic effects between the moieties and indicated that these derivatives possessed great potential as novel fungicides and require further research for the development of applications in crop protection.展开更多

In looking at the unification of private law, we need to follow three historical threads： the historicity of law, the rationality of private law and the rules governing the growth of private rights. Following on from and amending the Draft Civil Law of 2002, we can use restorative methods to formulate a nine-part civil code suited to China＇s national circumstances. The nine parts comprise the General Principles of Civil Law; Marriage and Family Law; the Law of Succession; Real Rights Law; Intellectual Property Law; Contract Law; Employment Contract Law; Tort Liability Law; and the Law of the Application of Law for Foreign-related Civil Relations. With this goal in mind, we can adopt a four-step legislative process： firstly, integrate the Marriage Law and the Adoption Law to form a unified Marriage and Family Law; secondly, include Employment Contract Law as a separate section of the civil code; thirdly, include Intellectual Property Rights Law as a separate section of the civil code; and fourthly, amend the General Principles of Civil Law so as to integrate Personal Rights, the General Principles of Property Rights （the General Principles of Obligation）, the General Principles of Commercial Law, etc. The civil code formed on this basis possesses historicity, flexibility and contemporaneity, and would become an important constituent in the restatement of Chinese civil life and the remolding of the Chinese system of law.展开更多

In the course of this long process, it developed distinctive legal traditions, including a tradition that prioritized agriculture, a stress on criminal law at the expense of civil law, an ethical orientation that stressed the five Confucian relationships, an approach to the legal traditions of different ethnic groups that embraced diversity in unity, and a Confucianized legal system based on virtue and ritual. These legal traditions were all based on the accretion of a deep-rooted legal culture which embodied the wisdom and creativity of the Chinese people. At the same time, they bore the stamp of China＇s national conditions： an economic structure dominated by agriculture, an autocratic political system, a multi-ethnic national structure, the preeminent position of Confucian thought, the uneven development of politics, culture and the economy, etc.展开更多

Decisions on authorization of experimental administrative reform have two aspects, viz., 'the temporary adjustment or temporary suspension of the application of certain provisions of a law' and 'authorizing a given experimenting body to implement this decision.' In essence, the former is the organic combination of two elements: suspending the implementation of a law and formulating a new experimental law;it does not belong under amendment of the law. The latter, on the other hand, is a special legislative authorization similar to administrative franchise. As a method of exercising public power, authorization for experimental administrative reform should follow the procedural requirements laid down in the Decision of the Central Committee of the CPC on Certain Major Issues concerning Comprehensively Advancing the Law-based Governance of China;further, it may not overstep the bounds of the forms of expression or substantive contents determined by the principles of the modern rule of law.展开更多
