When the range of the sludge grain size gets to 45-72 μm, sludge specific resistance decreases sharply.

同时污泥的粒径呈线性增加，当污泥粒径在45~72 μm之间时，污泥比阻的下降较明显。

For a higher packing fraction, a greater absorption strain was induced in the vessel packed with a larger initial powder size, while a greater desorption strain was present in the vessel packed with a smaller initial powder size.

在较高粉末填充率的情况下，较大的吸氢应变会出现在装填较大初始粒径粉末的储氢罐壁上，而较大的放氢应变则会出现在装填较小初始粒径粉末的储氢罐壁上。

Prevailing Keyring Alloy Products for jewelry \ letters tablets tablets DIY series, Hot Products are the market.

Dynamic smoke aerosol of five European standard test fire,including open wood fire(TF1),smoldering cotton fire(TF3),polyurethane fire(TF4),N-heptan fire(TF5),and methylated spirits fire(TF6),was measured by Scanning Mobility Particle Sizer Spectrometer,and smoke particle size distribution and particle number concentration were recorded and analyzed for studying the smoke dynamic coagultion effect.

采用扫描电子迁移粒径谱仪，对木材明火、棉绳阴燃、聚氨酯明火、正庚烷明火和工业酒精明火中产生的烟雾气溶胶进行在线测量，记录并分析随时间变化的烟颗粒浓度变化和粒径谱分布信息。

The results showed that the mixed surfactant had well distributed and uniform particles, and a size of 40-80μm. When the mass ratio of prepolymer and RDP was 1:1, the micro-capsule size was minimum, with little melamine resin deposited on the surface.

结果发现，复合型活性剂对微胶囊具有很好的分散作用，制备出的微胶囊颗粒均匀，粒径经检测在40~80μm；预聚体与RDP的质量比为1：1时，微胶囊的粒径最小，且只有少量蜜胺树脂沉积在微胶囊表面上。

Telomerases are very interesting DNA polymerases in that they carry an RNA template for the telomere sequence within them.

端粒末端转移酶是一种非常有趣的DNA多聚酶，它们带有决定端粒序列的RNA模板。

That's all icing sugar is - crushed granulated sugar.

放点糖粒在混合器里，糖粒一破就全成糖粉了。

Starch grains in hard wheat flour appear firmly embedded in a continuous protein matrix so that fracture of endosperm cells is more likely to crack starch grains.

硬质小麦面粉中的淀粉粒看起来牢牢地被包埋在连续的蛋白质基质中，从而胚乳细胞的破碎吏容易使淀粉粒破裂。

The expression of PCDNA〓-EGFP plasmid was monitered withfluorescence microscope,and the human thyroid undifferentiated carconoma in situmodel and haematogenous metastasis model were established in nude mice withPCDNA〓-EGFP positive cells.These model were used in discussing tumourmetastasis mechanism and early diagnosis of secondery tumour.

荧光显微镜观察〓-EGFP质粒表达情况，并用转染了PCDNA〓-EGFP质粒的细胞建立人甲状腺裸鼠原位及血源移植模型，探讨其转移机制及转移灶的早期发现。

These observations appear, in theory, to suggest that life-threatening cancer progression could be indefinitely avoided by the roughly decadal reseeding of all our stem cell pools with autologous ones that had been engineered ex vivo to lack the genes for telomerase or ALT, but to have long telomeres.

在理论上，这些观察显然提示了，威胁生命的癌症进展可以被无限期地避免，办法是大约10年就用自身干细胞来种植一次我们的全部干细胞库――这些自身干细胞已在体外经过加工，使其缺乏端粒酶基因或 ALT 基因、但有很长的端粒。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
