The phase change of soil moisture and inflation of the frozen moisture c ause the reduction of hydraulic conductivity by reducing the area of flow section and the aperture of soil pore space , increasing the capillary resisting force to soil moisture , and decreasing the water potential gradient because of the increasing of movement distances of soil water 导水率减小是冻结土壤入渗能力减小的根本原因，而土壤中液态水的相变是导水率减小的根源所在。土壤水分的相变及其膨胀通过减小土壤水分过水断面面积和孔隙孔径，增大阻力和由于增长运动距离而减小水势梯度使冻结土壤的导水率降低。
The information entropy in spatial distribution reaches the climax in changleng town , shigang town , wangcheng town and lehua town , where have a relatively developed economy , drops to the bottom in songhu town , xiangshan town , lianyu town and tiehe town , first ascends and then descends in 1997 - 2004 ( reaches to the climax in 2002 ) in ten towns like xishan town , shibu town , liuhu town , and so on 信息熵的空间分布，在新建县经济比较发达的长?镇、石岗镇、望城镇及乐化镇的信息熵最大；松湖镇、象山镇、联行乡、铁河乡的信息熵最小；西山镇、石埠乡、流湖乡等10个乡镇的土地利用结构信息熵在1997 - 2004年呈先增大后减小的趋势， 2002年达到最大。
Kds of 125i ~ on several minerals increased with increase of mineral ratio in mixed materials under atmosphere and low oxygen ambience ; and decreased with decrease of ratio of mixed materials and liquid under atmosphere . under the same condition , kds of 125i " on chalcopyrite and galenite were larger than kds of 125io3 " 大气条件下，随溶液初始ph值的增大， 125i -在黄铜矿、方铅矿上的kd值均呈减小的趋势；而在低氧条件下，随溶液初始ph值的增大， 125i -在方铅矿上的kd值增大。
Ptc heater uses the ptc heating sensitive resistance as the heating source . it is widely use in the air - conditioner , warm drier and warmer etc . as the secondary heating . the resistance value of the ptc heater will rise or reduce with the change of the environment temperature as it makes the ptc heater has the features of energy saving , even heating , safe and long life . it is widely welcomed by a lot of customers Ptc加热器是采用ptc热敏电阻元件为发热源的一种加热器，广泛用于空调器的辅助加热和暖风机取暖器等电气设备上， ptc热敏电阻元件因具有随环境温度高低的变化，其电阻值随之增加或减小的变化特性，所以ptc加热器具有节能恒温安全寿命长等特点，被越来越多的用户所欢迎。
The value of inlet gas velocity decreases and the reductive effectiveness of the mc increases when only decreasing the value of channel width . by changing the marangoni number alone , we found that the less the marangoni number , the less the needed inlet gas velocity and the better the reductive effectiveness of the mc 随着的增大，要想达到热毛细对流的最佳抑制，所需要的气流冲刷速度反而越小；但抑制程度随着值的增大有一个先增加再减小的过程，当为2时抑制程度达到最佳。
Because of the low angle is often beyond the distinguishing range of music algorithm , to get better doa estimation results , we make use of the well performance elevation distinguishing of the transform based covariance differencing algorithm , improve and apply it to doa estimation , which can both reduce the correlation between signals and improve target ’ s elevation distinguishing 但是由于低空目标的仰角常常超出了music算法的角度分辨范围,为了获得较好的仰角估计效果,本文利用基于变换的协方差对消算法在角度分辨上的良好性能,将其与改进,应用于低空目标doa估计,既减小的信号的相关性,又提高了角度的分辨率。
As a result , the young ' s modulus of the composites decreased a little during the heating process , which indicated that ceramics were thermal stable . on the other hand , it decreased from ~ 280gpa to ~ 220gpa as ni - fe content was increased from 0 to 19vol . % . this is reasonable considering that the young ' s modulus of ni - fe is much lower than the matrix 结果显示，材料的杨氏模量随温度的升高而不断减小，但减小的幅度很小，表明陶瓷材料稳定性很好；不同复合材料的杨氏模量随ni - fe含量增加自280gpa减小到220gpa ，这应该是因为ni - fe合金的杨氏模量比基体氧化铝的要小的缘故。
According to the results of other researchers , the strength of cement - stabilized soil reinforced with different nanometerial are compared . the studies shows that the ucs of narcss increases with the increase of curing period , increases firstly and then falls with nano - al2o3 mixing ratio , and increases with cement mixing ratio . according to the influencing degree , the main factors can be rated as following : cement mixing ratio , water content , nano - al2o3 mixing ratio , the w / c ratio 研究表明：掺纳米材料al _ 2o _ 3水泥土强度随龄期的增加而增长；随纳米铝掺入比增加呈先增大后减小的趋势，峰值出现在纳米铝掺入比为5左右；随水泥掺入比的增加而增加；在影响纳米铝水泥土强度的各因素中，水泥掺入比的影响最为显著，土样含水量影响次之，纳米铝掺入比的影响再次之，而水灰比的影响较小。
It was shown that the value of the in - plane was different at r _ ( iid ) = 0 when the mbds in the compressed state was softened . the value of the in - plane was decreasing at r _ ( iid ) = 0 with the increase of the static bias fields , thus it is proved that vbl in the walls of mbd is irregular and there exists a direction along which the vbl in the domain walls annihilate most easily 随着产生枝状畴时的直流偏场的增加，枝状畴在r _ ( iid ) = 0时所对应的面内场值是逐渐减小的，证明了枝状畴畴壁中的vbl是随几分布的，也从另外一个角度证明了在面内场作用下vbl的消失存在一个最易方向。
