蒸发率

The evaporation of ZrO2 will absorb heat and relieve erosion from oxyacetylene flame on the ablated surface of the specimen, and also accelerate the mass loss of the specimen, which leads to the decrease of the linear ablation rate and increase of mass ablation rate of the composites.

产物ZrO2的蒸发吸收了材料烧蚀表面的热量，减缓了火焰对烧蚀表面的冲蚀，材料的线烧蚀率减小，然而， ZrO2的蒸发会增加材料的质量损失速度，导致材料的质量烧蚀率增大。

The experimental results show that: lithium is scatteredly precipitated as natural lithium carbonate in the whole evaporation process, and the highest content of natural lithium carbonate in solid phase is 2.0%, so it is difficult to get the mixed salt with high-grade lithium carbonate; boron is precipitated as borax in the whole evaporation process, and borax is precipitated in large quantity with the highest content of 15.64% in solid phase until the brine is extremely concentrated (CWR≥97.9%) and intergrows closely with typical cold-phase natron; potassium is precipitated as sylvite and aphthitalite in the whole evaporation process with a content from 9.49% to 34.44%.

结果表明：在低温蒸发状态下，锂以天然碳酸锂形式在整个蒸发过程中分散沉淀，固相最高含量仅达2.0%，因此难以获得较高品位的富锂混盐；硼在全蒸发过程中以硼砂形式自然沉淀。当卤水高度浓缩（蒸失率达97.9%以上）时大量析出并与典型冷相矿物泡碱紧密共生，固相中硼砂含量最高可达15.64%；钾以氯化钾和钾芒硝形式沉淀，在蒸发浓缩的全过程中均有不同程度析出，固相含量在9.49%~34.44%之间波动。

The results showed that the sandy soil in layered soil profile can stimulate or obstacle the water movement as compared to the uniform loam column with 50cm depth of water table, this was mainly determined by the position of the sand layer.

结果表明，砂层对于水分的蒸发既有促进也有抑制作用，在地下水埋深为50 cm时，5 cm厚的底砂层可使水分的蒸发强度增加10%～20%；砂层距水位的距离大于5 cm时，砂层可抑制水分的蒸发，且当距离增加到35 cm左右，其抑制率可达70%～80%；当砂层距水位的距离继续增大时，水分的蒸发强度基本保持不变。

GM-type refrigerators have been used for over 10 years on magnetic resonance imaging cryostats for the purpose of reducing the helium boiloff rate.

旨在降低氦蒸发率的双级GM制冷机在磁共振成像低温恒温器中应用已有10多年的历史。

Sea water's salinity varies from that of the saltiest waters (such as the desert-bound Red Sea with a high evaporation rate and little inflow of freshwater) to one of the least salty (the Baltic Sea where there is a high inflow of freshwater from rivers).

海水的含盐量不同，在saltiest水域（如沙漠约束红海的高蒸发率和很少的淡水流入），以一个最不咸（波罗的海那里是一个高的淡水流入从河流）。

The water flux increased and retention decreased with the increase of the additive content, the decrease of pre-evaporate time, the decrease of evaporate pre-temperature in blend system. One can control the performance and structure of the membrane by changing composition of coagulation bath and temperature.

随预蒸发时间的增加，膜的水通量降低，截留率上升；随预蒸发温度的升高，水通量下降，截留率上升；通过改变凝固浴组成和温度，可以调节膜的结构性能。

Conventional tillage with bare ground, conventional tillage with straw incorporated and no-tillage with straw mulch were studied in the Hexi corridor of Gansu provience. The result showed: on summer fallow NTS stored soil water more than CTB and CTS by 30.62mm and 23.91mm, respectively; the winter storage irrigation quotas should be reduced to 900~1350 m^3/hm^2 on winter fallow; evaporation controlling rate arrived 38.1% and 7.3% at winter storage irrigation quotas 975m^3/hm^2 and 2100m^3/hm^2, respectively; NTS did not reduce ET during the spring wheat growth stage; yields different between treatments was not significant.
