  condensation point
It is shown that the only singularities of the function f(p, h) are first-order poles for real h = hn >amp;lt; 0 (n = 1, 2, ...) with the condensation point h = -1, which form an infinite discrete (countable) set.
      
Optimum operation temperatures are near to the condensation point of each gas species.
      
The finite radii of grains are about from 0.01 μm to 0.6 μm depending on the density near the condensation point, the velocity of matter outflow, and the stellar effective temperature.
      
In the present formulation, weight functions can be calculated by using a general-purpose finite element code combined with analytical expressions near the condensation point, where hyper-singularities exist.
      
Numerical results are reported for the two order parameters and for the quasihole and quasiparticle energies, as functions of temperature through the condensation point.

  pour point
The experimental results indicated that the anomalous rheological behavior of EVA copolymer, widely used as a flow improver, is related to its efficiency in reducing viscosity and depressing pour point of crude oil and waxy solvents.
      
The eigen-temperature of virgin crude is almost equal to its pour point, while the eigen-temperature of PPD-beneficiated crude is much lower than its pour point.
      
Gel point or pour point is the temperature indicating the gelling of waxy crude, and is widely used for evaluating the low temperature flowability of a crude oil.
      
This shows that the temperature at which storage modulus equals loss modulus is just the pour point of waxy crude oil.
      
Gel point or pour point is widely used to evaluate the low temperature flowability of crude oil.

Of all the possible ways of increasing Reynolds number,operating the wind tunnel at cryogenic temperature has been shown to offer significant advantages. Reynolds number similitude can best be achieved in existing big wind tunnels with cold nitrogen as the test medium. Cooling the test gas in the wind tunnel to cryogenic temperature by spraying liquld nitrogen into the wind tunnel.circuit must expend a considerable amount of liquid nitrogen during operation. Consequently it make the operation cost much expensive,besides the atmospheric environment is also polluted due to the cryogenic exhaust nitrogen in large quantities. The cryogenic wind tunnels with liquid nitrogen as the cooling source make only effectual use of vaporization heat,however the energy carried in cryogenic exhaust which is equiv alent to the vaporization heat is wasted in vain. For recovering of the cryogenic energy,an improved means of cooling test gas to cryogenic temperature has been developed. An additional heat exchanger is attached to the outlet of a cryogenic wind tuunel. After both the compressed air and the cryogenic exhaust flow through the heat exchanger,the former is cooled and the latter is heated. The precooled compressed air flow again through a thermal separator which cool further it to cryogenic temperature. The experiments for proof of concept has been completed. The inference according to the results of the experiments shows that the sources of air with intermidiate pressure (2.5 MPa) for conventional Wind tunnel satisfy enough the requirment for generating cryogenic flow with normal pressure in transonic wind tunnel.

降低风洞气流总温是提高亚、跨声速风洞雷诺数的有效方法。现有采用液氮致冷的生产型低温风洞能满足设计各种新型飞机进行气动试验所需的雷诺数要求,但由于需耗用大量液氮,导致运行费用高昂,此外,排出大量低温缺氧气体还严重影响生态和环境,为此本文提出一种新颖的致冷途径。首先在风洞排气口添置双向式热交换器。利用排气携带的冷量将流入风洞的压缩气体预冷。既回收利用了排气的能量,同时还将排气温度提高。预冷过的压缩气体再通过热分离器进一步将温度降至近冷凝点或使其凝结,分别用作直通型或回流型低温风洞的气源。原理性实验结果及其推算表明:常规风洞使用的中压气源就能满足常压、低温风洞运行要求。

· AIM: To evaluate the effects of cryotherapy on peripheral retina and ciliary in treating neovascular glaucoma that cannot be treated with retinal photocoagulation for various reasons.· METHODS: Twelve cases (12 eyes) with neovascular glaucoma that cannot be treated with retinal photocoagulation due to refractive media opacity and small pupil. Different number of points for cryotherapy were selected according to their medical histories and degrees of high intraocular pressure (IOP). Cryotherapy lasted for 30-40s per point.· RESULTS: The IOP in all the cases was controlled, and the neovascular on iris disappeared. Eyeball atrophy occurred in 2 cases.· CONCLUSION: Cryotherapy is an effective therapy for eyes with neovascular glaucoma that cannot be treated with retinal photocoagulation due to refractive media opacity, especially those that have lost visual function.·
