Results The total aberrantion rate of chromosome is 26.7%(23/86);Compared the normal controls,in azoospermic patients,Serum FSH、LH levels increased,The rate of T/LH decreased.and there is a very significant difference(P%26lt;0.05);The resemble results is detected in different outcome in PESA.

结果摘要：86例无精子症患者中异常核型23例，占总例数26.7%；和正常对照组相比较，无精子症组血清FSH、LH升高，T/LH比值下降，差异有显著性(P%26lt；0.05)；PESA能抽吸到精子组比不能抽吸到精子组的FSH、LH偏高，T/LH下降(P%26lt；0.05)。

Our calculation shows that qa decreasing with the simulationtime can accelerate the convergence significantly,which is somehow similar tointroducing different temperatures for visiting and acceptance probability.

为了增加收敛速率，让原来固定不动的qa随计算机时间作线性下降，对粒子数N＝12，51的Thomson问题的测试表明我们的改进效果是很明显的。qa随计算机时间作线性下降类似于对接收几率引入了单独的温度，这个温度不同于跃迁温度。

The stem flow of spruce and larch had acidulation on the soil, but the soil around the bole of spruce didn't present intensive acidity (the lowest pH of water and KCl immersion were 5.13 and 4.79, respectively), so the acidulation of stem flow is not the direct reason of spruce death.

虽然两树种树干径流对土壤均产生了酸化作用，但由于云杉树干周围土壤PH并没有出现较强的酸性（水浸pH下降到5.13，盐浸pH下降到4.79），因此，还不能认为云杉的衰退死亡与树干径流的酸化作用有直接关系。

This research shall be obtain that ocean-sand motor shall have more compressive strength early, but later strength shall descend, by means of non-standard sand mixing sample is quite obvious. By means of 50% ocean-sand substitutes for river-sand to mix fine aggregate compressive strength early shall be risen 20%~30%; Adds slag to ocean-sand or a half of river-sand and ocean-sand to make motor test sample, Compressive strength、bending strength and tensile strength shall be according to slag additament, by means of. slag add itament substitutes for cement 40%~60% is most. But slag be able to substitute for cement is too enough, 1ater strength shall be descent.

由本研究可得知海砂拌和的水泥砂浆，其早期抗压强度较高，而晚期强度则有下降的趋势，其中以非标准砂拌和效果最为明显；若以50%海砂替代河砂做为拌和细骨材，其早期抗压强度约上升20%~30%；添加炉石於海砂或河砂、海砂各半的水泥砂浆，其抗压、抗弯及抗拉强度，会随著炉石添加量增加而增加，其中以40%~60%炉石替代量为最佳，但是炉石替代量过高，晚期强度会下降；在相同水灰比状况下以海砂拌和水泥砂浆做比较，以非标准砂拌和有较高的抗压强度，其强度约比标准砂高10%左右。

The CaM level of Ginkgo and Ailanthus decreaseunder long time salt stressand level of CaM in Ginkgo decreases more slowly than that ofAilanthus.

长期不同强度盐胁迫条件下，银杏和臭椿叶片的CaM水平下降，耐盐性强的银杏CaM水平下降幅度较小。

Level of CaM of leaves in Ginkgo and Ailanthus is sensitive to drought stress:theCaM level of Ginkgo first decreased and then increased,CaM level of Ailanthus went ondecreasing along with stress strengthen.

银杏和臭椿叶片CaM水平对干旱胁迫敏感：随着胁迫加强，银杏CaM水平出现先下降后上升的趋势，臭椿CaM水平持续下降。

50Mmol/L NaCl stress had no influence on level of ATP in root of Ginkgo andAilanthus.Level of ATP in roots of Ginkgo,Ailanthus and Robinia decreased greatly under200mmol/L NaCl stress.The extent of decrease of ATP level accord to plant salt tolerance:Ginkgo is more salt tolerance,and ATP decreases more slowly than that of Ailanthus andRobinia.

11.50mmol/L的NaCl胁迫没有引起银杏和臭椿根尖ATP水平的明显改变；200mmol/L的NaCl胁迫引起银杏、刺槐和臭椿ATP水平指数性的衰减，ATP的下降幅度的变化与植物耐盐性一致：耐盐性强的银杏，ATP的下降幅度明显比刺槐和臭椿小。

Straight form type the characteristic advantage of horn fan air exhauster: 1, simple case of lumber of FRP fibre glass, acid-proof alkaline, anticorrosion. 2, the efficiency that prevent rain is extremely tall, do not have the worry of ooze water.

直结式喇叭扇抽风机之特点优势：1、FRP玻璃纤维材料外壳，耐酸碱，防止腐败蚀。2、防雨速率非常高，无渗水之苦恼。3、没变动之苦恼→4、没下降抽风力之捆扰。5、没下降抽风力之捆扰。6、省修理，省修养→能够应用10~20年以上。

In grain-filling stage, the qP values of evolutionary wheats decreased under water stress, while Shan253 and Changwu134 hadn't decreased, indicated that the effect of water stress on the re-oxidation in Q-A of modern wheat was slight, while before this stage, the electron transport from PSⅡto QA restrained by water stress was main factor of photosynthesis non-stomata limitation to modern wheat; The qNP values of hexaploid were higher than diploid and tetraploid wheat, indicated that the ability of using light energy

随小麦由二倍体向四倍体、六倍体及现代小麦进化，表观电子传递速率有增大趋势，其受水分胁迫影响的程度在花前期有加剧趋势，花前期栽培一粒、栽培二粒、普通小麦、陕253和长武134这五种小麦在水分胁迫下表观量子产额的降幅分别为5%、7.47%、14.29%、33.3%和53.49%，光饱和Pn的降幅分别为8.8%、26.14%、23.25%、44.22%和51.29%，光饱和点整体上也是下降的，且这三个指标的降幅随进化程度提高有增大趋势，表明小麦在进化过程中能量转换系统受水分胁迫影响的程度加剧；而在水分胁迫下，小麦的羧化效率和RuBP再生速率也均下降，下降的程

Shrinking world soybean meal supplies, due to a lower U.S. soybean crop, and increased domestic production are expected to result in a resurgence of Indian soybean meal exports, estimated at 2.7 million tonnes for 2003, USDA says. Lower production and strong domestic demand during 2002 resulted in reduced soybean meal exports, estimated by USDA at 1.3 million tonnes.

美国农业部说，在美国大豆产量的下降造成世界豆粕供货量下滑的情况下，印度国内产量的上升预计将使印度豆粕出口量回升，2003年预计将达到270万吨。2002年产量的下降及国内需求的强劲势头使豆粕出口量出现下降，据美国农业部预计，当年的出口量为130万吨。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
