The echolocation signals of Rhinolophidae and Hipposideridae are both long CF-FM with 1 harmonic and narrow FM bandwidth. But Rhinolophidae has longer duration, higher duty cycle and lower dominant frequency than Hipposideridae. All the echolocation signals of Vespertilionidae are short FM with 2-6 harmonics and wide FM bandwidth. Vespertilionidae has shorter duration and lower duty cycle than the other two families. There are obvious differences in dominant frequency between different species in this family.

菊头蝠科和蹄蝠科回声定位信号均为长CF-FM型，一般具有1个谐波，调频带很窄，但菊头蝠科的持续时间和能率环明显高于蹄蝠科，蹄蝠科能量最大处频率高于菊头蝠科；蝙蝠科回声定位信号均为短FM型，具有2～6个谐波，持续时间和能率环比其他两科低，调频带很宽，能量最大处频率在种间变化较大。

Grobler 和 Boden 等人的研究发现，下位腰椎小关节的矢状走向的程度与退变性腰椎滑脱之间存在相关性。

The patients with lower serum glycine or D-serine levels, more severe negative symptoms and cognitive deficits, abnormal expression in mRNA or protein levels of certain genes (e.g., lower expressions of SHMT2, PSAT1 and serine racemase; higher expressions of AMT and ASCT1) may be more likely to respond to sarcosine.

此外，用药前具有较低的血清glycine或D-serine浓度、较明显的负性症状或认知功能缺损、以及特定基因於mRNA或蛋白质层次表现异常(如：SHMT2、PSAT1及serine racemase表现较低，而AMT及ASCT1表现较高)的患者，可能对sarcosine有较佳的治疗反应。

The constructor-China Sinoma International Engineering Co., Ltd chosed the process of sieving crushing system, based on experiment and by improving process and operation, sucessfully improved the lower grade limestone's w by 2% and reduced the total content of silicoaluminate by 9%, realized using lower grade limestone as cement raw material.

承建方中国中材国际工程股份有限公司，在实验研究的基础，采取了石灰石筛分破碎系统的工艺方案，并通过优化工艺布置和操作控制举措，使低品位石灰石的w值提高2%以上，硅铝类氧化物的质量分数合计下降9%，成功实现了低劣品位石灰石作为水泥生产原料成为可行。

Copper levels in skin fibroblasts of the involved vitiliginous skin were much lower than those of the uninvolved, but slighty lower than or the same with those of controls.

近年来发现白瘫风患者的血清铜和铜蓝蛋白含量降低囚，作者对白瘫风患者的皮损区、周围区的皮肤成纤维细胞进行了细胞培养和铜含量测定。

The inhibition substances in Sorbus pohuashanensisHedl fruit not only restrained the seeds of wheat, cabbage from germinating but also restrained height and root growth. After the seeds of wheat, chinese cabbage had been soaked in the water extraction of pulp, seed and decoated seed for 8h, the seed germination rates were 92% and 84%, 89% and 65%, 94% and 78%, lower than the control, especially the water extract of decoated seed; and the root length and seedlings height were lower than the control, especially the water extract of pulp, and decreased in sequence of soaking time from short to long. So the simplest and effective method to eliminate pulp soluble inhibiting substances is to wash fruits by flowing tap water soon after collection.

在几种浸泡时间中，浸泡8小时的去皮种子浸泡液对白菜、小麦种子发芽率的抑制作用最为明显，其发芽率分别为65%、89%，但随着浸泡时间的延长而降低；浸泡8h的果肉浸泡液对白菜和小麦幼苗高生长和根伸长的抑制作用最为明显，种子和去皮种子浸泡液(8h)的抑制作用对小麦和白菜的抑制作用次之，随着浸泡时间的延长，果肉浸泡液的抑制作用逐渐减弱，因而采收下来的果实及时净种是清除果肉水溶性抑制物质简单有效的方法。

The peak of lesion sporulation appeared on the 27th day. The most suitable temperature for sporulating was 24℃. If relative humidity was lower than 88%, the lesion could not sporulate. Between 90% and 100%, the higher the RH was, the higher sporulation was. If continuous humidity time was lower than 5 h, the lesion could not sporulate. Between 7 h and 24 h, the longer it was, the higher sporulation was.

病斑产孢潜能高峰在日龄27d，产孢最适温度为24℃，相对湿度在88%以下，病斑不能产孢，在90%~100%范围内，随相对湿度增加产孢量急剧增加，在连续保湿5h以下，病斑不能产孢，在7~24h范围内，时间越长，产孢量越大。

Pollen germination rate on stigmas, pollen germination rate on culture medium and stainable pollen grain rate by I-KI of the four cultivars on average under high temperature were 16.00, 25.85, and 11.74 percentage points lower than those under nonnal temperature at that time, and 8.49, 6.63, and 6.02 percentage points lower than those under normal temperature at 4 days after treatment.
