Let r 3, n r and π = (d1, d2, . . . , dn) be a graphic sequence. If there exists a simple graph G on n vertices having degree sequence π such that G contains Cr (a cycle of length r) as a subgraph, then π is said to be potentially Cr-graphic. Li and Yin (2004) posed the following problem: characterize π = (d1, d2, . . . , dn) such that π is potentially Cr-graphic for r 3 and n r. Rao and Rao (1972) and Kundu (1973) answered this problem for the case of n = r. In this paper, this problem is solved completely.

In this paper, a new trust region algorithm for nonlinear equality constrained LC1 optimization problems is given. It obtains a search direction at each iteration not by solving a quadratic programming subprobiem with a trust region bound, but by solving a system of linear equations. Since the computational complexity of a QP-Problem is in general much larger than that of a system of linear equations, this method proposed in this paper may reduce the computational complexity and hence improve computational efficiency. Furthermore, it is proved under appropriate assumptions that this algorithm is globally and super-linearly convergent to a solution of the original problem. Some numerical examples are reported, showing the proposed algorithm can be beneficial from a computational point of view.

The digestive system of Cymatium pileare consists of buccal cavity, oesophagus, stom- ach, intestine, anus, salivary glands and liver. There is a contractible 'Argobuccinum' form proboscis in the anterior extremity of its body, and the buccal cavity lies in the anterior part of the proboscis, with a pair of jaws and a piece of radular ribbon. The jaws have many neatly arraned sickle- shaped sharpen denticles. Its dentition formula of radula is 2- (7) 1' (5-6) I (5-6) .1 (7) .2. In the middle of oesophagus, there is an expanded crop, which has the function of temporary food stor- age and preliminarily digesting food. The stomach is U-shaped and there are 2 entrances for liver ducts in its ventral side. The intestine is short and can be divided into 2 parts based on the structure of epithelia of their inner walls. The inner wall of foreintestine is stratified columnar epithelium, but the inner wall of hindintestine is pesudostratified columnar epithelium. The salivary gland of C. pileare is toxic gland and the toxin extracted from it plays a great role on its predation. The liver of C. pileare is compound tubuloacinar gland with mitochondrion, rough endoplasmic reticulum, Golgi comples and lysosome in its glandular cells.

基于对"构成要件符合性"的理解不同,学界形成了限制正犯概念与扩张正犯概念两种对立的基本立场,构建了不同的犯罪参与论体系;以犯罪事实支配论为理论基础,间接正犯概念得以摆脱"替补性"的地位,但是此一概念的存在,却使通说建构犯罪参与论体系的前提面临崩溃的边缘,逻辑立场的一致性丧失殆尽;不论我国刑法关于共犯的立法模式是倾向于区分制还是单一制,在限制正犯体系与扩张正犯体系之下都不应有间接正犯概念的存在。
