The challenges of these material are screen printing and sintering process. Many long fine patterned lines should be printed on a large piece of glass and sustain a smooth, continuous and uniform line pattern; on the other hand, the sintering process is rapidly increasing sintering temperature to a peak in a short time, then cooling the glass substrate to low temperature under a short time shock.

汽车钢化玻璃除霜加热线，是采用在玻璃基板上印刷银浆，在玻璃的钢化热处理过程中完成银导体膜的烧结附着，由于烧结时间短(总时间250sec)和温度骤变条件相当苛刻，要求导电细线无脱落断线，在功率满足要求的情况下，与外蓄电池连接的电极的焊接及附着强度也有具体要求，另外耐候性及耐擦洗等后步要求也较苛刻。

The brand-new electric and manual adjustable big curved, wide vision rear mirror, right under view mirror, wide view mirror, front under view mirror increase vision areas and effectively eliminate blind area.The original cab windshield and window heater which has withstood severe test under temperature of minus 30℃ in Heihe, a freezing cold area of Northern China, defrosts quickly and provides good field of vision under all weather conditions for the drivers.The high luminous crystal patternless halogen headlamp features dual lamps illuminating functions. Equipped with steering auxiliary lamp, it effectively widens visual angle when the vehicle turns and ensures safety when driving during nighttime.

全新电动及手动调整的大曲面、大视野后视镜，右俯视镜、广角镜、前下视镜增加可视区域，有效消除盲区；独创的驾驶室风挡、车窗暖风，除霜快捷，经历中国高寒地区黑河零下30度的严峻考验，为驾驶员提供全天候良好的视野保障；水晶无花纹卤素大灯，亮度高，具有双灯点亮功能；豪华版匹配转向辅助照明灯，在车辆转弯时，能有效扩大视角，保障夜晚驾驶同样安全。

Take the opportunity of this project, theoretical and experimental researches on the high-efficiency evaporator used in a large quick-freeze equipment have been done. The main work of experimental research is as follows:(1) Compare and analyze the influences of structural parameters on the heat transfer coefficient of an evaporator. The calculation results show that, under non-freezing conditions, the structure possessing the highest heat transfer coefficient is the one with circular fins, equilateral-triangle arranged small tubes and varying fin-spacing.

主要做了以下几方面的试验研究工作：(1)对不同翅片形状、管径大小、翅片管排列方式，以及是否带波纹等结构参数对蒸发器传热系数的影响进行了比较分析，得出在不结霜工况下，具有最高传热系数的蒸发器结构是圆翅片小管径正三角形排列等节距结构的结论。

UDZ Series liquid level indicator of flap disassembly fast and convenient, the installation position can be arbitrary choice, free to change the direction of observation, thus instrumented great visibility; UDZ series of cost-effective liquid level was significantly higher than that used multiple sets of glass plate liquid level of cost performance; UDZ series of liquid level indicator, the sender's device, as well as the liquid level with the main transmission medium within the complete separation of the measured structural design, so that level gauge in the job has pressure (up to 320KG), toxic and inflammable conditions, with absolute safety and reliability; UDZ-3 type uses innovative design, improve the sensitivity of the sensor, and its near-zero drift FarEasTone signals and long-term stability so that it has always been at the scene consistent level instructions; sensors and the main body has a certain interval, which can be solved effectively under high-temperature liquids (up to 480 ) remote detection and control; antifrost type UDZ Series Level Gauge, are I plant the patented product (Patent No.: ZL00221022 3), guarantees that the use of cryogenic liquid level gauge is not freezing (such as liquid CO2), the effective guarantee of the level of a normal job.

UDZ系列液位计的翻板指示器拆装快捷方便，安装方位可任意选择，观察方向可随意改动，因而仪表指示的可视度很大；UDZ系列液位计的性能价格比明显高于采用多组玻璃板式液位计的性能价格比；UDZ系列液位计的指示器，发讯器、以及液位变送均与主体内被测介质完全隔离的结构设计，使液位计工作在有压（可达320KG）、有毒和易燃的工况下，具有绝对的安全性和可靠性；UDZ-3型采用了新颖设计，提高了传感器的灵敏度，其远传信号近乎零温漂和长期稳定性使其始终于现场液位指示保持一致；传感器和主体有一定的间隔，因而能有效地解决高温液体（可达480℃）远距离检测和控制；防霜型UDZ系列液位计，是我厂的专利产品（专利号：ZL00221022·3），保证了在低温液体上使用液位计不结冰（如液体CO2），有效的保证了液位计的正常工作。

The calculated results show that the frost formation on airside heat exchanger and its effect on the performance of whole unit varies with running condition, i.

计算结果表明，在不同的工况下，空气侧换热器的结霜情况是不同的，对机组性能的影响也是不同的。

Stayed Canhongtunjin, trees are depressed that they had braved the cold of autumn, Frost and proudly wore in full bloom, and with their light and that hint of floral petals and dotted with "endless Lamu Ringing down" autumn, with that cream Maple Leaf-shaped dyed a beautiful autumn scenery inside.

待到残红褪尽，万木萧条的秋天她们却冒着风寒、顶着严霜昂首怒放了，用她们那淡淡的花香和轻盈的花瓣点缀着&无边落木萧萧下&的秋，与那霜染的枫叶一道形秋季里靓丽的风景。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
