| 1 | Improved Implicit SPH Method for simulating free surface flows of power law fluids显示文摘Implicit smoothed particle hydrodynamics method has been proposed to overcome the problem that only very small time steps can be used for high viscosity fluids(such as power law fluids)in order to obtain a stable simulation.However,the pressure field is difficult to simulate correctly with this method because the numerical high-frequency noise on the pressure field cannot be removed.In this study,several improvements,which are the diffusive term in the continuity equation,the artificial viscosity and a simplified physical viscosity term in the momentum equation,are introduced,and a new boundary treatment is also proposed.The linear equations derived from the momentum equation are large-scale,sparse and positive definite but unsymmetrical,therefore,Conjugate Gradient Squared(CGS)is used to solve them.For the purpose of verifying the validity of the proposed method,Poiseuille flows with Newtonian and power law fluids are solved and compared with exact solution and traditional SPH.Drops of different fluid properties impacting a rigid wall are also simulated and compared with VOF solution.All the numerical results obtained by the proposed method agree well with available data.The proposed method shows the higher efficiency than traditional SPH and the less numerical noise on the pressure field and better stability than implicit SPH. | HAN YaWei QIANG HongFu HUANG QuanZhang ZHAO JiuLing | 2013 | Science China(Technological Sciences)2013，56，10： | 5 |

| 8 | The Indications and Clinical Curative Effects of Modified Neck Dissection in Head and Neck Cancers显示文摘OBJECTIVE Functional neck dissection was first described by Bocca and Pignataro in 1967. It has been used in clinical practice for years, but remains controversial among neck-surgery experts. This study was designed to evaluate indications and curative effects of functional-neck dissection (FND). METHODS One hundred and fifty-two cases which underwent FND were reviewed with an analysis of pathological specimens and follow-up datas. RESULTS The series of FND included 20 cases of tongue carcinoma, 23 cases of larynx carcinoma, 96 cases of thyroid papillary adenocarcinoma, 9 cases of follicular adenocarcinoma and 4 cases of medullary adenocarcinoma; the five-year recurrence rate for tongue carcinoma was 12.5%, 14.3%, 40.0% and for a larynx carcinoma was 20.0%, 16.7%, 50.0% in N0 stage, N1 stage, N2a stage, respectively. The 5-year recurrence rate of thyroid papillary adenocarcinoma was 6.5%, 7.1% in N1a, N1b, respectively. CONCLUSION Functional neck dissection is indicated in early and low malignant head and neck neoplasms and results in satisfactory curative effects. | GuohaoWu WeiweiUu FujinChen ZongyuanZeng HaoLi MingSong MaowenWei QuanZhang AnkuiYang WenkuanChen | 2004 | Chinese Journal of Clinical Oncology2004，1，1： | 0 |
