结霜的

Frost process and change process of frost thickness of evaporator surface are studied.

需要研究蒸发器表面的结霜过程和霜层厚度的变化过程。

How to solve the problems mainly relies on the frosting and defrosting, and the performance of the unit of heat pump.

这些问题的存在主要取决于机组的结霜与除霜工况，取决于机组的性能。

Frost formation in coolers and refrigerators is disadvantage, research on frost formation is helpful for improving the defrosting methods.

结霜是影响制冷设备工作的不利因素之一，对结霜发生的研究可以指导改进除霜方案。

The air equipment is different from those on sale, it uses air-to-air total heat exchanger to prevent frosting and dewing.

该通风设备与当今市场上销售的通风设备不同，采用全热交换防结霜、结露措施。

On the one hand, the frost layer increases the thermal resistance in the airside, on the other hand, as the frost continued to grow, it restricts the airflow in the evaporator and also insulates the cooler surface from the air.

由于霜层的形成和增长对低温条件下蒸发器的性能有很大影响，因此，对蒸发器结霜过程进行理论和实验研究是非常必要的。

An analytical model to simulate the performance of evaporators for indirect cooling refrigerators under frosting conditions was established. The mass of frost accumulating on the evaporator surface, the airside pressure drop, the frost density and thickness were calculated.

在改进现有的计算霜表面水蒸气过饱和度公式的基础上，建立了适用于间冷式冰箱蒸发器的霜层生长模型，并模拟出结霜过程中的结霜量，空气侧压降，霜的密度和厚度随时间的变化。

Easy Bake oven, one yellow cake mix, one chocolate flavored frosting mix, one sugar cookie mix, two baking pans, two cooking utensils, instruction/recipe booklet, two warming cups, and a pan pusher.

简易烤炉，一个黄色的蛋糕组合，一个巧克力口味的结霜的组合，一糖饼乾组合，两个烤锅，两个炊具，指令/食谱小册子，2变暖杯，一盘推。

Sublimed water from freeze-drying materials frost on cold trap continuously by vacuum pump on vacuum freeze-drying process.The arresting efficiency of cold trap became worse and worse along with frost coagulating,and it would be bad to vacuum pump.

真空冷冻干燥过程中，从物料中升华出来的水分在真空泵的抽吸作用下，不断地在捕水器表面结霜，随着霜在捕水器表面不断凝结，致使其捕水效率不断降低，对真空系统形成不利的影响。

O my God, what am I That these late mouths should cry open In a forest of frost, in dawn of cornflowers.

哦，我的上帝，我是什么呀竟使这些来迟的嘴张开呼叫，在结霜的森林，矢车菊的黎明。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
