认为在影响欠平衡钻井的钻井液静液柱压力、环空压耗、欠压值、井口回压、地层压力中，地层压力是首先要搞清楚的最基础的压力，最好先求出地层压力而不必急于进行欠平衡钻进，因为一切欠平衡的压力计算都是建立在这个基础压力之上的；再根据地层压力确定合理的欠压值，确定所用的钻井液密度。

The Hardy-Weinberg equilibrium for genotypic distribution was estimated by the goodness-of-fit test. The UNPHASED program was applied to perform the transmission disequilibrium test, the haplotype analysis and the pair-wise measure of linkage disequilibrium between these 2 SNPs.

利用拟合优度χ2检验分析基因型分布频率是否符合Hardy-Weinberg平衡定律，应用UNPHASED软件包进行2个SNPs的传递不平衡检验、单倍型分析和连锁不平衡程度的测量。

The British composer Tim Salter wrote Equipoise for Xuefei Yang when she performed in the Park Lane Group Young Artist Series at the Purcell Room in January. She premiered it here and received much success with the piece from the general music critics who attended the concert. The piece is virtuosic and gives her the opportunity to display her superior technique and her enormous dynamic range. The concept of expressing balance and counter-balance was her idea and then Salter has balanced delicacy of line with powerful explosions of notes.

英国作曲家添索特的〝平衡〞，是为杨雪霏的〝帕宁集团年青艺术家〞一月份的普赛音乐厅演奏会系列而委约创作，她的首演非常成功，获得主流音乐圈的高度赞誉，这是一首超技乐曲，提供了一个机会让杨雪霏展现她出类拔萃的超群技巧和异常巨大的动态，索特以优美旋律混合具爆炸力的音符，由杨表达出平衡与反平衡的概念。

Through once again on the M14-6-X55 to take measures to reduce the balance of the block, the well balanced conservation block 2, balance rate from 60% to 87.5%, saving 28 degree day, the pilot was a success.

通过再次对M14-6-X55采取减少平衡块的措施后，该井节约平衡块2块，平衡率从60%上升到87.5%，日节电28度，试验取得了成功。

The qualitative and quantitative analysis of schizophrenia and single nucleotide polymorphism of catechol-O-methyltransferase , Proline Dehydrogenase and DYSBINDIN genes were done by using transmission disequilibrium test . Results:(1) The symptoms of first-episode schizophrenia were divided into four independent symptom dimensions: psychomotor poverty, reality distortion, disorganisation and depression-anxiety.

4采用传递不平衡检验、单倍型传递不平衡检验和定量性状传递不平衡检验的方法对6号、22号染色体上3个候选基因，即儿茶酚氧位甲基转移酶(catechol-O-methyltransferase，COMT)、脯氨酸脱氢酶(Proline Dehydrogenase，PRODH)和DYSBINDIN基因的9个单核苷酸多态性(single nucleotide polymorphism，SNP)位点与精神分裂症、神经认知功能、人格特质和临床症状表现的关系进行了定性和定量的遗传学分析。

The process of balance is on thealternation of arch and beam、 explores the space-time law of separatedstrata"s occurrence、 development and distribution and this paper damasks theoverlying rock as injecting zone and no-injecting zone from the aspect of controllingoverlying rock.2.The separated strata is over fracture zone and under integral crook zone inwhere the rock formation"s moving is of monolayer or of many layers more oftenthan not, and the thickness of strata is very small while comparing with integralcrook zone.

通过物理模拟及数值仿真模拟的实验研究，分析了采动覆岩的移动与破坏过程，提出了采空区上方覆岩的平衡形式是以拱和梁交替作用来实现平衡→失稳→再平衡的力学过程观点，并详细研究了覆岩中离层产生、发展与分布的时空规律，进而从覆岩控制角度划分了可充填离层带与不可充填离层带，为实际应用奠定基础； 2。
