Their 95% effective concentration (EC95) value was 0.4735 μg/mL. Flumorph at the concentration of 0.5 μg/mL, can lead the inhibit rate of growth of mycelium, formulation of sporangium and germination of zoospore of Phytophthora sojae to 100%, the concentration was lower than Apron XL, Metalaxy which lead to the same inhibition rate. It indicated that Flumorph can obviously inhibit the growth of P.sojae in vitro, and effect is better than that of Apron XL and Metalaxy.

结果表明：氟吗啉对所测定的菌株4个发育阶段均有显著的抑制作用，氟吗啉对大豆疫霉菌菌丝生长EC50 值为0.1906μg/mL，EC95 值为0.4735 μg/mL；在0.5 μg/mL 浓度下对大豆疫霉菌孢子囊形成和孢子萌发抑制率达100%，低于达到相同抑制效果的金阿普隆和甲霜灵；说明该药剂在离体条件下能够有效抑制大豆疫霉菌的生长，效果好于金阿普隆和甲霜灵。

The results indicated that two new compounds have higher fungicidal activities in controlling Pseudoperonospopa cubensis of cucumbers under the concentration of 500, 250 and 150 mg/kg, as compared with metalaxyl.

试验结果表明，其中两种化合物在复筛中，对黄瓜霜霉病菌在500，250，125mg／kg浓度下，与对照甲霜灵相比，具有较高的杀菌活性。

When it shows the current temperature, and it can show the temperature of the defrosting temperature sensor.

A distributed parameter model was proposed to simulate the airside heat transfer of the finned-tube evaporators in the frosting process.

建立了结霜条件下翅片管蒸发器空气侧流动和换热的分布参数仿真模型，模型考虑了蒸发器结构、霜层厚度以及湿空气状态等参数在气流方向的沿程变化。

A distributed parameter model is proposed to simulate the airside heat transfer of the finned-tube evaporators in the frosting process. The variation of the evaporator structure, the frost thickness and humid air conditions along the flow path are taken into consideration.

建立了结霜条件下翅片管蒸发器空气侧流动和换热的分布参数仿真模型，模型考虑了蒸发器结构、霜层厚度以及湿空气状态等参数在气流方向的沿程变化。

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。

The land between the lakes looked the same: on one side, Little Lee, frosty surface glittering in sunlight within a frame of golden reeds, streaked by long blue shadows from snow-laden trees.
