查询词典 condition of positivity

The result showed that the strong storm followed by mesoscale squall line was primary cause of strong sandstorm producing, steps and ladders short wave trough of 500 hPa was great criterion triggering system for the mesoscale squall line producing, the essential dynamic condition was provided by distortion field and the mesoscale low pressure of 700 hPa for the strong sandstorm forming and maintaining in mid-west of Hexi Corridor, the deep vertical circulation development condition was basic power that urged squall line to occur and sand dust to curl up, which was provided for the deep convection development by superimposition of lifting movement before ground cold front and ascendant current of secondary circulation in upper air jet entrance region, temperature and the barometric gradient around the cold front was enlarged by enhancement of ground thermal low and temperature diurnalvariation of afternoon, by which essential thermal energy unstable condition was provided for the gale and strong sandstorm eruption, the strong sandstorm appeared in downstream of -200 m^2s^(-2) center of vertical helicity, the vertical helicity had good instruction significance for development of squall line and landing region of sandstorm, the mesoscale squall line occurred in unstable stratification, basic condition of potential energy transforming as kinetic energy was provided by strong unstable stratification for the strong sandstorm forming and developing.

结果表明：中尺度飑线所伴随的强风暴是产生强沙尘暴的主要原因；500 hPa阶梯短波槽是中尺度飑线产生的大尺度触发系统，河西走廊中西部700 hp变形场、中尺度低压为强沙尘暴形成和维持提供了必要的动力条件；地面冷锋前上升运动与高空急流入口区次级环流的上升气流的叠加，为深对流发展提供了深厚的垂直环流发展条件，是促使飑线发生和沙尘卷起的基本动力；地面热低压的加强和午后气温的日变化加大了冷锋前后的温度和气压梯度，为大风、强沙尘暴爆发提供了必要的热力不稳定条件；强沙尘暴出现在垂直螺旋度为－200平方公尺/s^2中心的下游，垂直螺旋度对飑线的发展和沙尘暴的落区具有较好的指示意义；中尺度飑线发生在不稳定层结内，较强的不稳定层结为强沙尘暴形成、发展提供了位能转化为动能的基本条件。

Prof. Long-Ruilin mentioned that if we want to study weighted inequalities for martingales, such as the maximal inequalities, the inequalities for the square operator and so on, the condition imposed on weights are mainly A〓 and S, but we don't know whether this condition is superfluous in all problems we consider. Since the condition can not be weakened for the known operators, now we consider a new operator to discuss its L〓-boundedness, then another problem arises, under what condition can we get it?

龙瑞麟先生曾经提到要讨论关于可测的鞅的极大算子、均方根算子以及条件均方根算子的L〓有界性，或它们之间的〓有界性时，所设的主要条件是A〓与条件S，有了这两个条件在讨论加权问题时基本上没有什么困难，但是要想用更弱的条件来代替它们，即使在古典情况下（此时S条件是自然满足的）也恐怕还不到时候。

This paper advances the five proposals to promote college English teaching to train up the high-quality talents by quality education from the following aspects: improving the teachers' qualities and encouraging them to use English actively, setting up the right conception of quality education; motivating the students' activity, positivity and creativity in and outside class; carefully choosing and fully using the teaching materials, finding the connotative meaning; fully utilizing the modern equipments and other means; advisably making use of the examinations and their effects.

论文提出从提高教师自身素质，鼓励教师成为一名积极的语言实践者，并树立正确素质教育观；在课堂内外调动学生学习的积极性、主动性和创造性；慎重挑选并充分利用教材，挖掘教材的内涵意义；充分运用现代化的教学设备；合理利用考试的反拨作用等五个方面把素质教育融入到大学英语教学中，以期培养出高素质的人才。

Dreaming about all the great things that you can achieve is the key toa life filled with positivity. Let your imagination run amuck andcreate the world that you would wish to be in.

幻想着所有你可以完成的伟大事业能够使你的生活充满积极让你的想象力任意驰骋，尽情创造你想要的一切吧。

The rate of PPD positivity had no statistical differencebetween atopy and nonatopy in both groups.

PPD阳性率在两组中没有统计学差异。

Furthermore, additional research on the value of time to positivity and quantity of growth for differentiating culture contamination from bacteremia is necessary.

另外，有必要进一步研究区分血培养污染菌的生长时间和数量。

In order to bestir the positivity of the salesmen and strengthen the sales team to get more revenue, now we are going to study out the sales task, incentive and punishment program.

为了激励销售人员工作的积极性，加强销售队伍的管理给酒店创造更好的经济效益。

HCV positivity increased PTDM risk with 20% to 33% cumulative effect of bolus steroid and tacrolimus therapy.

HCV阳性会增加PTDM的发病风险，类固醇和他克莫司疗法会产生20%至30%的累积影响。

In terms of the positivity, compact support and normalization of B-spline basic function, the adjustment of the weights are accomplished locally and the output is simple. The results of the experiments show that the structure of the B-spline neurofuzzy-networks is clear and the training is more speedily than that of BP network.

在对刀具磨损状态进行监测过程中可以看出，B样条模糊神经网络内部的连接结构透明，可以很方便的根据实际需要调节网络结构，进行网络的优化来得到更加理想的诊断结果，同时证明了B样条模糊神经网络的训练速度优于BP网络。

The research shows that asymmetry information can cause sluggish behaviour for the same type of employees, the exogenous layoff probability can restrain labour positivity and threaten the efficient labour of the employees, and reduce the agent cost. While endogenetic layoff probability cannot impact on the function of the assembled mechanisms consisting of promotion and fixed income under asymmetry information, which can avoid the moral risk of employees to achieve the same degree of their labour under symmetry information.

研究表明：非对称信息会诱导同类员工偷懒行为，外生裁员概率抑制员工的劳动积极性，对员工的有效劳动构成一种威胁，但裁员概率降低了代理成本；外生裁员机制并不影响信息非对称下的晋升激励和固定收入组合机制持有的避免员工道德风险的功能，实现员工对称信息下的努力程度；以绩效评估为特征的内生裁员机制能够促使异类员工更加努力工作，提高产量，相应地也增加了工资支出；高能员工比低能员工更努力，提高员工裁员绩效标准和高能员工比例，有利于降低代理成本。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.
