查询词典 less than or equal

Quantum dots are a kind of semiconductor nanopaticles with the radius equal to or less than the exciton Bohr radius. They have tremendous potential in the field of biology and medicine because of their unique and tunable optical properties (broad excitation spectrum, narrow emission spectrum, precise tunability of their emission peak and negligible bleaching, etc) as new fluoresent probes.

量子点是半径小于或接近于激子玻尔半径的一类半导体纳米晶，作为一种新型的荧光标记物，其独特和可调谐的光学特性（宽的激发光谱、窄的发射光谱、可精确调谐的发射波长以及可忽略的光漂白等）使其在生物和医学方面显示出巨大的应用潜力。

Can be seen, no overload is the essence of the centrifugal pump, pump shaft power curve peak, or shaft power with the increase of flow rate changes are small, relatively flat power curve that axis, so that the pump shaft power in the dead lift off to zero head (that is, from zero flow to maximum flow rate) are less than equal to the original context of the supporting motive power.

可见，无过载离心泵的实质是指，泵的轴功率曲线有峰值或轴功率随流量的增加而有较小的变化，即轴功率曲线比较平坦，使泵的轴功率在关死扬程到零扬程范围内都小于等于原动机的配套功率。

He number of TCR V(Vα equal s to 100 and Bβ equals to 30 ) is less than the one of lg Vh (Vh equals to 300),for TCR V is subject to negative selection of major histocompatibility complex according to the neutral theory We discussed that is somatic mutation or DNA rea rrangement the main force in producing antibody diversity and are there pseudoge nes in TCR V or not.

CR V的数目(V α为100，Vβ为30)远少于Ig VH(数目为300)，原因是前者受到主要组织相容性复合体的制约，即受到负选择，这与中性学说观点相一致。文章还讨论了体细胞突变和DNA重排对两类抗体多样性产生上的作用，并探讨了Ig VH和TCR V的假基因问题。关键词分子进化，协同进化，免疫球蛋白，T细胞受体，中性学说

The most feature of the orbits of Near Earth Asteroids is that the semi major axes of the orbits are nearly equal to that of the Earth or the perihelia distances are approximate to or even less than the mean distance between the Sun and the Earth,thus they could move into inside of the Earth's orbit,so that th...

近地小行星轨道的最大特点是其轨道半长径与地球轨道半长径相近，或近日距离接近甚至小于日地平均距离，其运动可深入到地球轨道的内部，这将导致该类小行星与地球十分靠近甚至发生碰撞。

The researchers divided the 1,760 records of individuals in the two studies into five equal groups, from the lowest blood levels of 25D (less than 13 nanograms per milliliter, or 13 ng/ml) to the highest (approximately 52 ng/ml) of 25-hydroxy-vitamin D. The data also included whether or not the individual had developed cancer.

研究者划分器1760记录个人在该两项研究，分为5个平等的群体，从最低的血液水平， 25的D类（少于13毫微克每毫升，或13伍/毫升）的比例最高（约52霭仪/毫升） 25 -羟基维生素D的数据，还包括还是不单独制定了癌症。
