最低温度

The writer had investigated the medical stone heat-treat with DTA,XRD,IR.Research shows that the main crystal phases are SiO2,K6Fe2O6,Al2O3 at 1000℃.Temperature effect of far infrared on the element materials was weakening after Medical stone has been joined.

通过热分析、XRDI、R对在不同温度下处理的麦饭石进行测试，然后与Fe2O3、MnO2、TiO2、ZrO2进行混合烧结，研究结果表明，麦饭石在T=1000℃烧结时，主晶相为SiO2、K6Fe2O6、Al2O3，加入麦饭石后，样品的红外热效应略有降低，最低降低2.5℃，最高降低12.4℃。

In summer, the high-abundance distribution area of Pteropods is located in the place where the Taiwan Warm Current originates from Kuroshio.

结果表明，东海翼足类总丰度和出现频率有明显的季节变化，均为秋季最高，夏季次之，春季最低；总丰度在各个季节基本上呈东海南部高于北部、外海高于近海的分布趋势；春季的尖笔帽螺、夏季的锥笔帽螺、秋季的蝴蝶螺和冬季的马蹄螔螺是导致总丰度季节变化的最主要的种类；冬、春和夏3个季节丰度变化及4季总丰度的变化同表层或10 m层水温有非常显著的线性相关关系，与底层温度及盐度的相关关系不显著。

For the FA, the results indicated that the VPD calculation using mean of 24 hourly temperature values as saturation vapor pressure, and wet-bulb depression as actual vapor pressure yielded the lowest error, the least range, and the most frequency with the highest WI. These outcomes were as well as the SIA with the lowest EMSE, R^2 higher than 0.99 and the highest CE.

分析结果显示，以频率分析法而言，各地农业气候分区均呈现，VPD计算式以24个时温度日平均为饱和蒸汽压力，与湿球下陷量为实际蒸汽压力，具误差最少、全距最小、出现频率最多及最高权重指数，性能表现最佳，这样的结果，对照统计指标法之检测评估，同样具最低RMSE、R^2值0.99以上及最大CE，性能表现优於其他所有VPD计算式，两者，结果一致。

The effect of solid lubricants including polytetrafluoroethylene and graphite on the friction and wear behavior of the composites was examined on the same test rig as well.

结果表明：碳纤维使聚醚砜的摩擦磨损性能得到明显的改善，春改善程度同碳纤维的长度和体积分数相关；当碳纤维的体积分数约为15％时，聚醚砜复合材料的摩擦系数及比磨损率最低；添加固体润滑剂可以使复合材料的摩擦磨损性能得到进一步改善；随着温度及外载荷的变化，摩擦系数及比磨损率表现出不同的变化趋势。

With a constant space and different duty ratios, two conditions with high heat transfer performances emerged mainly due to the different degrees of influence of the heat transfer surface area and the rib thickness on the heat exchange performance.

以换热系数进行比较，当占空比为83％左右时，热沉表面温度最低，换热性能最佳；当间距恒定不变而占空比不同时，会出现两个换热性能较好的情况，主要是由于换热表面积和肋片厚度影响换热性能的程度不同。

Slab temperature variation entering the mill would be closely controlled, and exposure to air and consequent scalling would be minimized.

由于板坯进入轧机后温度受到严格控制，暴露在空气中的部位极少，因而可将氧化铁皮减少到最低程度。

Result: The shoe gum that contains toluene and fourth ketone its LC50 lowest, contain ester only kind shoe glue LC50 is highest; The LC50 of female Xiaobai rat is less than male Xiaobai rat; The LC50 when the temperature of shoe glue environment of akin composition is high is low; The symptom that the shoe gum that contains toluene and fourth ketone produces after contamination of small white rat is much, restore time to grow, pathology sees drop of liver lung haemorrhage.

结果：含甲苯与丁酮的鞋胶其LC50最低，只含酯类的鞋胶LC50最高；雌性小白鼠的LC50小于雄性小白鼠；同种成分的鞋胶环境温度高时LC50低；含甲苯与丁酮的鞋胶小白鼠染毒后产生的症状多、恢复时间长，病理可见肝肺出血点。

Hydrogen is also one of the coolest refrigerants.

氢是温度最低的冷冻剂。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
