It showed that except typical trophozoites in binary fission. the following trophozoites of abnormal morphs were also observed. for instance abnormal trophozoites with binary fission; enlarged trophozoites with round and irregular shaped eosinophilic bodies in the cell plasma; enlarged cells containing round and irregular shaped eosinophilic bodies and flagella; enlarged cells which contain 6 or 8 nuclear-like bodies and flagella, 3 or 4 embryonic forms of daughter trophozoite in one mother trophozoite; 4 trophozoite embryonic forms with fused plasma 3 trophozoites with fused plasma;4 trophozoites with fused plasma; a pair of trophozoite with binary fission fused with another trophozoite;2 pairs of trophozoite with binary fission fused each other; a trophozoite with 1 nuclear only.

结果 除观察到典型的营二分裂法繁殖的贾第虫滋养体外，还可见到多种形态异常的虫体，包括；虫体呈非典型二分裂；滋养体胀大，胞质中有团块状和不规则形状的嗜酸性物质；在胀大的贾第虫细胞内含有团块状和不规则形状的嗜酸性物质以及鞭毛；在胀大的贾第虫细胞内含有6或8个核状物以及鞭毛；在一个母体细胞中含有3或4个子体细胞的雏形；胞质互相融合的4个滋养体的雏形；胞质互相触合的3个滋养体，胞质互相融合的4个滋养体；1对营二分裂的滋养体与另一个滋养休互相融合；2对营二分裂的滋养体互相融合；仅有1个细胞核的滋养体。

First, Styela clavas tunica and its body are separated carefully so that interaction among some substances are prevented.

首先，将柄海鞘的鞘体和鞘囊进行精细剥离，避免了物质的相互干扰，更好的进行物质的定位。

Aged cheese contains a substance called tyramine, which happens from the breakdown of amino acid as food ages.

她说在完全成熟的奶酪里面有一种物质叫酪胺，这种物质是因氨基酸的分化而产生的。

The two volcanic materials are similar but are also different ①the partition mode of rare-earth element is similar to that of the basalt.②the increase content of the rare-earth element content in transitional layer shows that it enrichs in this segment due to the volcano events. Moreover, the comparability of the partition mode shows that the volcano-genic materials and the basalt are of the same source.③low Eu anomaly different from the high Eu anomaly of medium-acidic tuff in Meishan section, that show that their formation is different④there are plentiful basalt detritus.⑤there are enrichment of the Ti element.⑥the lower content of siderophile element of Ni and Co, especially in the transitional layer, show that there were not extraterrestrial events and big scale basic or ultrabasic volcano eruption events in this area. These characteristics show that the sedimentary source of Xuanwei Formation and Kayitou Formation is basalt.

1稀土元素配分模式与玄武岩类似；(2)稀土元素含量在异常层的增加反映了火山事件导致了它在该段地层中的富集，而配分模式的相似性反映了火山物质来源与玄武岩具有同源性；(3)低"Eu"异常区别于煤山剖面的中酸性凝灰岩高"Eu"异常模式，说明界线粘土岩成因也不同于煤山剖面的界线粘土；(4)大量的玄武岩岩屑；(5)Ti元素的富集；(6)亲铁元素Ni和Co含量较低，特别是在界线异常层含量降低，表明本区在界线处可能并不存在地外事件和大规模基性、超基性火山喷发事件，这些特征反映本区宣威组和卡以头组物质来源主要为玄武岩。

The rate of sedimentation depends on the molecular weight of the molecule and thus the ultracentrifuge and be used to separate a mixture of large molecules, such as large colloidal proteins, and estimate particle sizes.

物质沉淀率取决于分子本身的重量，所以可用超速离心机分离大分子混合物，如：大胶体蛋白，或用于检测物质颗粒大小。

The colloidal material concentration is calculated by using integral sample concentrations of ultrafiltrate and retention with concentrate factors

实际分析样品时，应选择合适的浓缩因子，固定的膜压及流速对样品进行分离，胶体物质浓度应用超滤结束后超滤液和浓缩液中的物质浓度结合浓缩因子进行计算。

Surface water was sampled at the three red tide stations during the Guinardia delicatula bloom in Jiaozhou Bay on February 9-10, 2004 and the colloidal substances were separated by filtration(0.7μm)and cross-flow ultrafiltration (1000 Daltons). The organic carbon in the filtrates and retentates were analyzed respectively. Heterosigma akashiwo and Skeletonema costatum were cultured in the 000Daltons ultrafiltrate and the retentates with different amount of colloidal substances (1000 Daltons-0.7μm).
