Focused on many problems existing in pressure control system of drilling pipe friction welding,such as high failure rate and poor amenability,the basic principles of friction welding and electro-hydraulic proportional technique were briefly described.

针对焊接钻杆连续驱动摩擦焊机采用开关阀组成压力控制系统存在故障几率高、可控性差等问题，将电液比例控制技术应用在摩擦焊压力控制中，实现了摩擦焊轴向压力闭环控制、滑台进给速度的开环控制；可对摩擦焊机主轴速度、轴向压力、轴向缩短量、主电机电流、油温等进行实时检测。

This result was consistent with the previous simulation study;(2) the signals of MAH onto the radical chain ends with double bonds increased markedly with increasing MAH content, indicating that P scission occurred after MAH attached to the tertiary carbons.

MAH的用量对接枝PP链的等规度有很大的影响，主要表现在随MAH浓度增加，PP链的mm序列所占的比例逐渐增大，mr和rr序列所占的比例逐渐减小。

The result shows, buy what the room is the first pressure to suffer inquirer scale to amount to 46%, parental health problem is amounted to into the scale of origin of the 2nd great pressure 38%, and of native place staying behind " empty nest parents " uncared-for wait for a problem, become " emigrant white-collar " in the heart painful.

结果显示，买房为第一压力的受调查者比例达46%，父母健康问题成第二大压力来源的比例达38%，而留守老家的"空巢父母"无人照顾等问题，成为"移民白领"心里的痛。

Single-component samarium diiodide catalyst system was first used with polymerization of acrylonitrile. Adding of hexamethylphosphoramide could greatly improve reaction activity of the catalyst system. AN/Sm12 and l{IVIPA1 Sm12 molar ratios, reaction time and temperature were mainly investigated with yields and molecular weights of resultant PAN.

研究发现HMPA的加入可以极大地提高催化活性；考察了单体与催化剂(SmI2)的摩尔比例、第二组分与催化剂(SmI2)的摩尔比例、反应温度、反应时间等因素对相应聚合物的产率和分子量的影响，通过对聚合物的红外和核磁的分析，提出了&单电子转移-双阴离子引发&机理。

新型花式纺纱机可以纺制大肚纱，圈圈纱， TT 纱，结子纱， AB 纱，包缠纱，圈圈 TT 复合纱等；四色针梳机可将不同成分的粗条根据比例来进行混条，纺制颜色渐进变化的彩色毛条；小针筒钩编机可以用长丝或纱线为原料，仿制空心带子纱，割毛纱，勾链纱等；多功能花式纺纱机可以纺制包芯纱，粗细纱，强弱捻纱，竹节纱等。

Percent and 21. 4 percent respectively. F1 plants of R01 self-cross also present diverse colors such as white, pink, red, nacarat/saffron, dark yellow, yellow and so on, And the pink and the nacarat/saffron plants have the highest proportions, 50.6 percent and 31. 4 percent, respectively. The wide segregation chromatogram of self-cross progeny implies that these two varieties themselves contain the abundant genetic polymorphism. The ISSR genetic diversity analysis and the principle factor analysis were performed using 49 plants of RP1 self-cross progeny population and 123 plants of R01 self-cross progeny population.

RP1及R01的遗传多样性最高，这从自交一代的表观性状及ISSR的遗传变异可以得到证实，如RP1自交，F1代花色有白色、粉色、玫瑰红、深红色、桔红/桔黄、黄色，黄红复色等，其中以粉色及桔红/桔黄色占的比例最大（分别占61.2％，21.4％）；R01自交，Fl代花色有白色、粉色、红色、桔红//桔黄、深黄色，黄色，其中以粉色及桔红/桔黄色占的比例最大（分别占50.6％，31.4％），较广的自交分离色谱，表明两个品系自身存在丰富的遗传多态性。

The results show that ordered phases precipitated and formed a pseudobinary system; precipitated earlier than g phase by a congruent ordering + spinodal decomposition mechanism and thus produced a nonstoicheometric ordered phase, then the nonstoicheometric g phase precipitated by a non--classical nucleation and growth mechanism at the boundaries of phases, meanwhile, both of them transformed to stoicheometric ordered phases.

研究发现该合金沉淀过程中，析出D022结构的(Ni3V)相和L12结构的Ni3Al相，二者构成伪二元系；相先于相析出，相的沉淀机制为等成分有序化+失稳分解，相在相的相界处非经典形核，二者均先形成非化学计量比有序相，之后向化学计量比有序相转变；随Al浓度增加，相析出变慢，所占比例减少，而相反之，析出越来越早且所占比例增加。

The experiment obtains clone pig HUMMLC2B gene (GenBank logs onto date: DQ533994), use PCR-RFLP technology, analysed HUMMLC2B gene the 1st embedded child medium Msp Ⅰ is enzymatic cut much condition (T613C) is in distributinging; analysed the much condition sex in 7 breed pig 5 many condition sex and 36 long white pigs, groups 104 pigs and grow to be mixed in vain 5, the result makes clear, the scale that waits for a gene and B to wait for a gene frequency except the A in long white pig in detected swinery is 1 ∶ 2 outside, of the others all take absolutely advantage for a gene such as B, and a gene such as A is pure close individual detect in long white pig only.

实验获得克隆猪HUMMLC2B基因(GenBank登录号：DQ533994)，并采用PCR-RFLP技术，分析了HUMMLC2B基因第1内含子中的MspⅠ酶切多态(T613C)在7个品种猪中的多态性分布；分析了多态性和36头长白猪、5个群体104头猪以及长白和5个群体之和的140头猪胴体性状和肉质性状间的相关，结果表明，在检测的猪群中除长白猪中A等位基因和B等位基因频率的比例为1∶2外，其余的均为B等位基因占绝对优势，且A等位基因纯合个体只在长白猪中检测到。

Macrophanerophytes such as pine and cedar are more and occupie greater percentage to from bottom to top, which are affected by clime and geography and human avtivity. Because people pay more attention to Macrophanerophytes and less to shrub and herbge plants, ecology of the forest is unbalance and benefit is low.

在整个沉积物柱的孢粉组合中，松、杉等大型乔木始终占有很高的比例，而且越到上部比例越大，这除了受滇中地区气候地理因素的影响外，可能还有人为的原因，人们在保护森林资源和植树造林过程中往往只是注重了大型的乔木而忽视了灌木和草本植物，从而使森林生态失衡，生态效益低下。

Corporate holdings account for the proportion of larger stock pot for the East to withdraw from the market, Datang Power Generation, Bank of Communications, Industrial Bank, since the instrument shares, and the reduction of the proportion of larger stocks in the Pacific for long Group century, too-long Chinese medicine, Tai shares, too, and so on of the shares.
