The lattice relaxation in the CVD diamond thick films were detected by the X-ray diffraction attachments. It is associated with self-annealing of diamond thick films in the process of long time deposition. The wearing discrepancy of diamond coated cuttings and diamond thick films brazed cuttings is well illustrated by means of lattice relaxation.

用X射线衍射仪的薄膜附件测试分析金刚石厚膜内的晶格松弛现象，发现沉积金刚石厚膜过程中存在高温自退火的作用，运用晶格松弛的观点很好地解释了金刚石薄膜涂层刀具与厚膜钎焊刀具的耐磨性能差异。

Thesources of self-pollution in agriculture production of Shanghai suburbs are mainlythe agriculture pesticides,chemical fertilizers,urine and excrements of fowls and animalsand the agriculture plastic films at present. Before the seventies,organic mercury pesticides and organic chlorine pesticides wereused in Shanghai suburbs.It influenced the environment greatly. During the eighties,thepesticides making great influence were mainly organic phosphorus and tyiethroids;the fer-tilizer causing great influence ...

上海市郊农业生产中的自身污染，目前主要有农药、化肥、畜禽粪尿和农用塑料薄膜。70年代以前，上海曾施用过有机汞、有机氯等农药，对环境的影响较大。80年代以来，影响较大的农药主要是有机磷和菊酯类；化肥主要是氮肥施用过多，导致蔬菜硝酸盐含量过高；畜禽粪尿已成为郊区突出的新污染源，造成水体的严重污染；各类农用塑料薄膜也是必须重视的新潜在污染物。

Generally only through the solvent and solute film can not call it ideal semipermeable membrane.

对透过的物质具有选择性的薄膜称为半透膜，一般将只能透过溶剂而不能透过溶质的薄膜称之为理想半透膜。

Shandong is the largest province in the amount of plastic sheeting, as well as plastic sheeting best reflects the trends in the development of new products.

山东是在塑料薄膜量最大的省份，以及塑料薄膜最能反映在新产品的发展趋势。

In the interior of PP films bulk density is obtained,while density drops off sigmoidally over a distance of ～0.8 nm near the free surfaces.

发现薄膜内部密度等于聚丙烯的本体密度，而离自由表面0.8nm处薄膜的密度开始跌落。

This method is built at the basis of similative of the mathematic relation between the torsion problem of pole and elasticity membrane which is under the action of equal side pressure and exaggerates tight around.

为了解决较复杂截面杆件的扭转问题，特提出薄膜比拟法。该方法是建立在柱体扭转问题与受均匀侧压力而四周张紧的弹性薄膜之间数学关系相似的基础上。

Based on the presumption that the deformed surface is described as a kind of surface of spherical cap, the problem about the relationship between load and deformation was resolved.

当载荷增大到一定程度，薄膜效应远远超过弯曲效应，此时板的弯曲效应可以忽略，因此圆板在大挠度状态下的特性更接近于薄膜特性。

The indentation loading curve with a spherical diamond tip was employed to determine the yield strengths and hardening indices of Cu films which were prepared on silicon substrates by different ways with the same thickness of 1. 5μm. The result showed that the yield strength of the Cu film depends on the deposition technology, and is much higher than that of the bulk material.

结果表明，在薄膜厚度相同的条件下，铜膜的屈服强度与铜膜的制备方法有关，选择IBED法较MS法可获得更高的屈服强度〓此外，由两种方法所镀制铜膜的屈服强度均远高于其体材，这与铝膜的情况相一致，说明薄膜与整体材料在强度方面存在显著差异的结论具有普遍性。

The separations of standing wave states between the films and substrates vary with the characteristics of the surface.

在Cu(111)及重构的Au(111)表面上镀上Ag薄膜，透过STS的量测，发现基板与薄膜的高能量驻波态会有ㄧ定量差值。

Cuttage is a breed method in virescence seedling producing, In order to find effective cuttage measures. Gardenia jasminoides, Stephanotis floribunda, Nerium indicum, 3 rooting substrates and plant hormones NAA,IBA were tested in the cuttage experiment, meanwhile all the treatments were dealed with 2 kinds of humidity keeping measures: ones covered with plastic membrane, the others covered none.

扦插是绿化苗木生产中常用的种苗繁育方式，为了探索在生产上成活率较高的扦插措施，本试验以白蝉、非洲茉莉、夹竹桃为扦插材料，采用3种生根基质、以500mg/l NAA和IBA溶液速蘸插穗切口进行扦插生根试验；同时以覆盖塑料薄膜和不覆盖薄膜进行保湿处理对比。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
