The pupae were exposed to 9 krad 60Co-γ rays for two days before emergence.The adults were dissected and many mature sperms could be seen in the male flies.There were no significant difference in the form,number and vigor of sperm between irradiatid and unirradiated male flies,but there were some abnormal ultrastructurail changes in the sperm of irradiated male flies such as the appearence of vacuoles in nutrient cells,disarrangement of sperms,variation of the number of chondriosome derivates,axonemes ction of formation and abnormal cell division of sperm cells.

用9krad辐照羽化前2天的蛹，成虫羽化后解剖观察，雄虫已有大量成熟精子，精子形态、数量和活力与未经辐照处理的雄虫无显著差异，但其超微结构则发生了某些异常变化，如营养细胞出现空泡、精子排列零乱、线粒体衍生体和轴丝增多或减少、构型被破坏、精子细胞分裂异常等。

Wavelet multi-scale analysis is applied to the research on lunar gravity field and the explanation of lunar inner structure. In this paper, the nearside of the Moon with higher quality data is chosen as the test area, and free air gravity data from "Clementine" mission are used as original data to decompose gravity of some specific mare basins. With the results of numerical test, we also explain the hierarchical structure of the Moon, analyze the thickness of mare fillings and the Moho topography under mare basins, and verify the results by comparisons.

The results show, when polar distance is bigger than the size of cross section of tunnel, the difference of anomalous feature between the corner-sections and wall-sections in tunnel is very small. The apparent resistivity is only related to the distance between section and bodies. The shielding effect of the tunnel is not so evident that the character and value of anomalous are similar with those in full space.

计算结果表明，当坑道内偶极测深的极距大于坑道截面尺寸时，坑道角与坑道面断面异常形态差异不大；视电阻率值只与断面和地质体间的距离有关；坑道空腔的屏蔽效应并不明显，坑道内各个测深断面的异常幅值和形态与全空间中观测结果非常相似。

The rats were killed by cutting theirnecks and physical blood was taken for preparing serum, interleukin 2 (IL-2) was detected by radioimmunoassay ; the spleen was taken for measuring ConA-induced reaction of lympho- cyte proliferation and induced production of IL-2; and the activity of induced production of spleen's IL-2 was determined by the means of cell proliferation of mouse thymus; the skin and trachea were taten for slice with paraffin wax, dyeing with methybenzoamine blue so as to survey mast cells .

将大鼠断头留取躯干血制备血清，用RIA法检测白细胞介素2（IL-2）；取脾脏行ConA诱导的淋巴细胞增殖反应测定和IL-2诱生；并用小鼠胸腺细胞增殖法检测脾IL-2诱生活性；取皮肤和气管做石蜡切片、甲苯胺兰染色检测肥大细胞，结果显示：应激组较对照组脾淋巴细胞增殖降低，cpm分别为9466±3.17和24019±3879（P.001）；MC明显减少，分别为8.6±3.0/HP和25.4±3.7/HP（P.001），前组形态异常较其甚（MC多较小，呈多角或不规则状），且组织中可见分散的崩解颗粒。

61Ppm, REE distribution patterns of apatite standarded by NASA are classified into two types: The one is concave,"hat-shaped" REE pattern which is slightly enriched in intermediate REE and has a weak or even wanting Ce anomaly. To which, the sandy phosphorite of Jile is representative; the rest REE pattern is shown by more or less complete curve, although distinct Ce negative anomaly or weak Ce positive anomaly is shown up well. The stromatolitic apatite is the representative of this type.

其稀土元素北美页岩标准化配分型式主要分为两类：一类为中稀土略显富集的帽状形态的稀土元素配分型式，微弱的铈负异常或无铈异常，以极乐矿段砂屑磷块岩样品最为典型；另一类为轻稀土、中稀土和重稀土自然分异的三段弧形折线衔接而成的稀土元素配分型式，铈负异常较明显或微弱的铈正异常，以叠层石柱体磷灰石最典型。

By synthetically analyzing the variation characteristics of pre-earthquake anomaly before five moderate-strong earthquakes in East China since 1990,discussing the pre-earthquake anomalous shape of b value and so on we obtained the comprehensive criteria for medium and short-term earthquake anomaly before moderately strong earthquake in East China:high YH value anomaly—low b value anomaly—low C and YH value anomaly—low Ds and Dt and Σ value anomaly and high b value anomaly—earthquake.

It is showed that MG132 significantly reduced the germination rate and tube growth. Furthermore, MG132 treatment lead to vacuolization occurred both in tube cytoplasm and generative cell. While DMSO and non-proteasome inhibitor E-64 do not have similar effects.
