首次对三元尼龙和蒙脱土复合进行了研究， tem结果表明：粘土片层杂乱无章地分散在基体中，平均厚度10nm ，形成剥离型纳米复合材料。 |
| 7. | Touke stratum was laid down in the pliocene and early pleistocene epochs . it is some 1500 meters thick on average , and rich in fossils . the fossil beds of tsailiao creek in tsochen were made famous by the discovery there in 1971 of the skull of " tsochen man .
也由于左镇乡的地质为上新世至更新世早期的头?山层，平均厚度为一千五百公尺，此层中含有丰富的海相滨海相淡水相等各类化石群，随著地壳隆起而露出成陆。 |
| 8. | Therefore , nowadays major problem is how to reduce the slope cultivated land ' s soil erosion and sediment concentration transporting to three gorges reservoir in order to prolong the three gorges engineering ' s use time and protect the safety of the middle and lower reaches channel of yangtze river
因此当前的主要问题是如何臧轻坡耕地土壤侵蚀，减少进入三峡库区的泥沙量，延长三峡工程的运转时间，保障长江中下游河道的安全。另外，按土壤平均厚度78 。 |
| 9. | Two wedge interferometers are designed that the thickness of one is higher than the other . so when the incident coherent light through the interferometers can acquire two fringe patterns which having space shift , but the incident incoherent light only result in consistent intensity signal . through a differentiating amplifier , two signals subtract which can eliminate noise of background and result in higher contrast ratio fringe signals . this method largely improves the system and the ability of detection . the spacing of line fringes is a function of incident laser wavelength , by analyzing , we can extract the wavelength of incident laser . the optical unit analyzing and results also simulated with matlab
当背景光入射时，直接穿过干涉仪，仅发生强度的衰减，在两个探测平面上产生幅度基本一致的灰度信号，通过差分放大器，相消为零，从而抑制了背景干扰。当激光信号入射，穿过干涉仪时受到调制，在探测平面上产生干涉条纹。通过所设计的存在平均厚度差的双楔形干涉仪，两路干涉条纹图案出现相对移位：在两个探测平面对应的位置上，一路出现亮纹，另一路出现暗纹。 |
| 10. | In part three , according to the viewpoint of system , giving consideration to all kinds of condition of forming hillslope debris flow , taking five indexes as follow : the shape index of ditch , the mean value of greatest precipitation within 24 hours , the developing degree of unstable mass , the mean depth of loose " accumulated clay and the rate of plant cover , applying fuzzy mathematics , the paper designs a suit of scheme about judging hillslope data
第三部分，依据系统的观点，全面兼顾了山坡泥石流形成的各种条件，选取沟谷纵剖面形态指数、最大24小时暴雨均值、不良地质体发育程度、松散堆积层平均厚度和植被覆盖率五个指标，运用模糊数学方法在室内设计出一套山坡泥石流沟与非泥石流沟的判定方案。然后以野外实例数据进行检验，结果表明本方案分辩率较高，为84 . 6 ，且偏于安全一侧。 |
