The seed embryoes were penetrated by 〓 ion beams of 75 MeV/u and the seed endosperms were implanted by the proper degraded 〓 ions, and soluble protein of the seedling in M1 generation was divided into 5 sections to analyze their changes at different molecular weight. 1 In comparison with control, the relative content of the second section (molecular weight is heavier in all sections) of all irradiated materials got down, while the relative content of the fifth section (molecular weight is the lightest) of those went up. 2 The penetrating seeds made the relative content of the first section (molecular weight is the heaviest) and the third section (mid-molecular weight) drop, while the fourth section went up. Moreover, the changes of the third section and the fourth section of the penetrated materials were clearly different from those of the implanted materials. 3 The difference between implanted embryo and implanted endosperm existed in deeper dropping of the first section and higher rising of the fifth section on relative content of soluble protein of the latter. 4 On irradiated materials at lower doses, there were exceptional changes of soluble protein, it may be thought that there was excited effect of low dose.

1.75MeV／u 〓O〓离子经过适当降能后注入小麦种子的不同部位和贯穿整个种子，对其M1代幼苗的可溶性蛋白质组分以及电泳中不同区段蛋白质组分相对含量加以分析，结果表明：1）同对照相比，随着辐照剂量的增加，所有辐照材料第二区段蛋白质组分的相对含量下降；而第五区段蛋白质组分的相对含量升高。2）种子的贯穿处理，同时也引起第一区段和第三区段蛋白质组分相对含量的下降以及第四区段的升高；其中第三、四区段的变化明显区别于注入效应。3）注入胚和胚乳的区别在于后者第一区段蛋白质组分相对含量的较大下降和第五区段的较大提高。4）小剂量辐照的材料，可溶性蛋白质组分的变化异常，可能与低剂量辐射兴奋效应有关。

The free water in wood is very closely related to the density change of wood during drying, so that the sound speed measured by tap tone completely obeys the physical law relating sound speed and properties of solid materials. 2. When moisture contents are higher than the fiber saturation point, the weight changes or the moisture content changes of the wood can be estimated with high accuracy by measuring the changes of sound speed using the tap tone method.

试验结果显示：木材中之自由水分在打音时完全表现在生材之密度变化上，因此打音音速完全遵守音速与材质关系之基本物理定律，故在含水率高於纤维饱和点之生材状态，利用音速变化来推定木材重量变化或含水率变化具有相当高的精度，是合理可行的。

The research of marsh initiated in the 1960s in our country. However, the study of marsh sedimentation and environmental changes was relatively weak, even though we have done some preliminary works on an approach to the characteristics of sporepollen assemblage of peat in the Holocene and paleoenvironmwent, and formation mechanism and deposition kinetics of peatland since 1990s. But we are lacking in systematic research on gleying marsh, especially on recent short timescale and highresolution sedimentation records of environmental changes. There is a certain disparity in this field compared with lake sedimentation and environmental changes.

我国沼泽研究起步于20 世纪60 年代，期间有关沼泽沉积与环境的研究相对薄弱，90 年代以来虽已在泥炭沼泽孢粉解译全新世环境变化与泥炭沉积动力学方面有初步积累，但对潜育沼泽缺乏系统研究，尤其缺乏近代短时间尺度高分辨率环境变化历史记录研究，这方面与湖泊沉积及其环境演变研究相比已形成一定的差距。

It was found that pathological changes could be demonstrated in villi of small intestine, lamina propria of stomach and myocardial cells in case of mice orally administrated with RV, while in case of mice intra-abdominally injected with RV, pathological changes could be demonstrated also in liver and kidneys in addition to the changes mentioned above.

结果 光镜下：RV口服组小肠绒毛、胃固有层、心肌细胞有改变；RV腹腔注射组除上述改变外，肝，肾也有改变；电镜下：肝细胞线粒体肿胀、凝集病变尤为明显，细胞核固缩－崩解，粗面内质网扩张，肝细胞中存在大量脂滴和空泡；毛细胆管明显扩张，微绒毛脱落。

There is, for instance, a kind of steel called invar (from"invariable") which does not change its dimensions as temperature changes; it is valuable for making pendulums, since, if the length of a pendulum changes, its time of vibration changes.

不过也有一两个例外，例如有一种钢叫做殷钢(从&invariable&一词而来)，在温度变化时它的大小尺寸不变；这种钢对于制造钟摆很有价值，因为如果摆长改变，摆动的周期就改变。

There are one or two exceptions. There is, for instance, a kind of steel called invar (from"invariable") which does not change its dimensions as temperature changes; it is valuable for making pendulums , since, if the length of a pendulum changes, its time of vibration changes.

The objectives of the study were to make clear the cellular, subcellular, molecular and dynamic changes of the involuting uterus in the postpartum ewes, the relationship between uterine degrading and apoptosis, the supersonic changes of the involuting uterine, changes of HYPRO and 3MHIS in peripheral blood and urine and their relationship with uterus involution, the relationship between microbial flora and uterine involution.

从而揭示了小尾寒羊产后子宫的细胞、亚细胞以至分子水平的变化规律，子宫的组织降解与细胞凋亡之间关系，小尾寒羊产后子宫的超声影像学变化，产后血和尿中HYPRO和3-MHIS含量变化与子宫复旧的相关性，以及子宫腔内微生物区系与子宫复旧的关系等问题。

The width of lapels changes, the number of buttons changes, even the number of pockets changes.

翻领的宽度会变，纽扣的个数会变，连口袋的数量都会变。

Wrights class theory has great significance in practice to our understanding of the new changes in class relations of contemporary capitalism and the development of Marxism according to the new changes: Firstly, Wright'theory of the new changes in contemporary capitalist class relations will enable our understanding of this class structure to be founded on more complete analytical data, and make us have a more accurate knowledge and understanding about the non-applicability of Marx's prediction in his class theory of polarized class relations in capitalism.

赖特的阶级理论对于我们认识关于当代资本主义社会阶级关系新变化并且根据这种新变化来发展马克思主义具有很大的现实意义：首先，赖特的当代资本主义社会阶级关系新变化的理论，使我们对当代资本主义的阶级结构的认识能够建立在比较完整的数据分析基础之上，也使我们对马克思所预言的资本主义阶级关系两极分化的阶级理论在当代的不适用性有了更加准确的认识和了解。

We compared the changes of T reg cell levels pretransplant and short courses posttransplant, the changes of T reg cell levels between the acute rejectors and the stables,and the changes of T reg cell levels between CsA group and FK506 group.

对比术前和术后近期T reg细胞水平的变化，移植肾功能稳定组和急性排斥组T reg细胞水平的变化，CsA组和FK506组T reg细胞水平的变化。
