Building new regional medical consortium in the model of trusting county-level hospitals to provincial-level large-scale public third-level grade-A hospitals can optimize the allocation of medical resources, promote two-way referral system and rational shunting of patients, and drive multi-sited practice of physicians. Furthermore, it can constantly improve regional medical service level, and achieve the goal of medical reform—comprehensive reform of county-level public hospitals. By introducing general situation where two county-level hospitals are trusted to Hubei Provincial People’s Hospital, this study analyses its operation performance and existing problems, and then puts forwards developmental countermeasures and recommendations for provincial-level hospitals to hold county-level hospitals in trust to build a medical consortium, including driving reorganization of medical resources, making clear roles of all the parties concerned, clarifying internal governance structure of hospitals under trust, reinforcing policy guidance, enhancing internal developmental force of trusteeship, intensifying supporting, and improving functions of medical consortium incrementally.

The direct-billing collaboration between medical institutions and commercial health insurance institutions is an internationally applied method of commercial health insurance claims. This paper discusses the reasons why the direct-billing service of medical institutions is currently limited, including the trivial size of commercial health insurance and hospitals’ concern on cost control, by taking the practice of direct-billing service in a certain hospital in Wuhan as an example. It also summarizes the problems encountered in the operation, including the refusal to medical payment, the risks in excessive medical care, the increasing costs of medical institutions and acting against the equalization principle of medical service. The author then proposes several advices on the direct-billing service operated by hospitals, in terms of strengthening the risk control, taking part into the “Big Data” health management, reforming HIS system united with commercial insurance institutions and adjusting the pricing system of direct-billing service.

As the core component of hydrodynamic variable speed transmission system of wind turbine, there exist some problems in domestic adjustable torque converter, such as simple products and poor performances. A three-dimensional flow simulation method is employed to design the adjustable torque converter. Circulatory circle is determined after the structure optimization of the torque converter. The blades are designed by the conformal projection law, and then the adjustable device’s structure is determined. The performance of torque converter with the variation guide vanes is analyzed by using numerical simulation. The calculated results show that the new torque converter could meet the needs of the wind turbine transmission system.

Reasonable determination of indoor ventilation rates are the main content of residential ventilation designs, and can save consumption by air conditioners. Firstly, the energy saving potential of ventilation cooling technology in Guangzhou is analyzed in this paper. The cooling load of a residential building in Guangzhou with different air exchange rates is simulated by the DeST-h after indoor heating quantity of different rooms is set. The energy saving rate is analyzed, the functional relation between energy saving rate of ventilation and air exchange rate is obtained using the linear-regression analysis method. After a comprehensive consideration of various factors, including variation of energy efficiency, room volume, air outlet size, and that the maximum air exchange rates of different rooms are fixed.

We present the potential of ultrathin bilayer metallic nanofilms for use as broadband antireflection coatings in the terahertz frequency range. The metallic layers are modeled using a wave-impedance matching approach. The experimental and theoretical results are in good agreement. Further, a novel method using our broadband antireflection coatings is proposed to eliminate unwanted reflections that interfere with the important reflection from the sample in terahertz reflection measurement. The proposed method significantly improves the calculation of the optical properties of liquid and biological samples.
