Ink-jet technology is a kind of applicabal technology, low-speed business card printing machine has grown very, very high speed in industrial inkjet card field to keep the ink－jetprinting head of stability, reduce printer paper error expansion caused by overprinter, anti-weathering, resisfance, and so there are many pending further study on the subject in the future.

喷墨技术是一种适用性很强的技术，民用低速制卡机已经发展得非常完善，但在工业用超高速喷墨制卡领域，保持喷墨头的稳定性、减少承印纸张伸缩导致的套印误差、耐候性、耐水性等方面还有不少有待今后进一步研究的课题。

The results showed that length from flag leaf pulvinus to spike base has the largest coefficient of variance of 42.1% and 37.2% in both DS and WW environments, respectively, while the spikelet per spike has the smallest CV of 6.4% and 5.7%. Under different water regimes, spike number per plant, effective spikelet per spike and peduncle length contribute a lot to the stable grain yield. Genetic diversity indices of DTI were from 1.95 to 2.07, with an average value of 2.02. Based on the DTI of agronomic traits, all accessions could be clustered into seven groups, the first and third groups are not sensitive to the water regimes, and the second group is more suitable for planting in dryland.

结果表明：在雨养和灌溉条件下，穗叶距的变异系数最高，分别为42.1%和37.2%，单穗总小穗数的变异系数最低，为6.4%和5.7%；不同水分条件下，植株稳产性主要受单株穗数、有效小穗数及穗下节长的影响；性状耐旱指数的多样性指数在1.95到2.07之间变化，平均值为2.02；根据性状耐旱指数将供试材料分为7个类群，其中第I、第III类群材料表现为对水分条件不敏感，而第II类群材料更适于在干旱条件下种植。

本课题分析具有局域电荷槽结构的SOI LDMOS的纵向耐压机理，提出界面电荷耐压模型，这是迄今为止所见报道的高压SOI器件理想的新模型。

In order to enhance the anti-corrosive performance of ZK60 magnesium alloy,the chemical conversion coating s on ZK60 magnesium alloy obtained from phosphate or stannate solutions were studied.

结果表明：在磷酸盐溶液中，当处理温度为50℃时，磷化30min后试样的电荷转移电阻为224.03Ω·cm2；当温度为80℃，反应时间为45min时，所得转换膜的Rct为377.67Ω·cm2，阻值最大，耐腐蚀性能最好；对于锡酸盐化学转化膜，90℃下，处理60min的膜层耐蚀性能最好，其Rct为388.32Ω·cm2，与磷酸盐化学转化膜相比，两种膜的保护性能相差不大。

From the calculation results of an example, it is found that the total probability of failure of a structural system will not equal to the sum of the probabilities of failure for all the individual failure modes.

从其对耐压圆柱壳的计算结果可以看出，潜艇耐压圆柱壳结构的失效概率并不等于各失效模式的失效概率之和，这不同于Faulkner做出的求和理论假定。
