The focal length of an objective lens is an important factor in an optical system. There were many methods to measure the focal length of an objective lens. The fixed-focal length collimator method had a large measurement range and high accuracy. The relative error was generally less than 1%. It was a commonly used measurement method. In a telescope, the multiplying power was equal to the focal length of the objective lens divided by the focal length of the eyepieces. In terms of aperture, the F value was the ratio of the focal length of the objective lens (f) to the perimeter of the entrance pupil (D). Different types of telescopes or instruments had different focal length values of the objective lens. For example, the focal length of an astronomical telescope was 400mm, and the focal length of the objective lens of the ZWJ - 851 Collimator was 200mm. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The objective response of the tumor could be seen from the values of tumor markers and imaging examinations. ** 1. Value of tumor marker ** 1. ** Commonly used tumor markers and their normal reference values ** - ** Carcinoembryonic Antigen (Carcinoembryonic Antigen)**: Normal indicators should be less than 5 ug/L. It is a broad-spectrum tumor marker and is often used as a reference for cancer such as intestinal cancer, stomach cancer, breast cancer, or colonic cancer. If the indicator is more than two times higher than the normal value and continues to increase, it is necessary to pay great attention to eliminate the possibility of tumors. It may increase in cancer such as cancer of the intestine, stomach, lung, breast, uterus, etc. However, benign diseases such as digestive tract inflammation, polyp, lung inflammation, and long-term smoking may also cause a slight increase. - ** Alpha fetoprotein (Alpha Fetoprotein)**: The tumor index of a normal person should be less than or equal to 25 ug/L. It is mainly used as a reference for primary hepatoma or gonadal embryonic tumor. When diagnosed with primary liver cancer, the positive rate in China was generally 60% - 70%. Normal people's serum levels were <20 ng/ml. When the serum levels of AFPs continued to increase by more than 500ng/ml for one month or more than 200ng/ml for two months, the possibility of liver cancer was highly suspected. However, in pregnancy, severe liver disease, liver Cirrosis, Testicular cancer, Entodermal cancer, teratoma, Ovary cancer, and gastric cancer with liver metastasizing, the serum levels of AFPs would also increase. - ** Carbohydra Antigen 125 (CA125)**: It is a kind of protein. About 60% of patients with malignant tumors will have an increase in serum CA125, and it should quickly return to normal after surgery. Patients with relapse of malignant tumors often have an increase in serum CA125 before there is any relapse, which is a good indicator for determining the effect of chemotherapy on malignant tumors. However, some patients with malignant tumors do not have an increase in serum CA125. In addition to malignant tumors, there are also lung cancer, cervical cancer, uterus cancer, uterus cancer, gallbladder cancer, and gastric cancer. Cancer and other malignant tumors, as well as benign gynecological diseases (such as edema, uterus myoma, adenomyosis, Pelvic inflammation, and menstrual period) can cause it to increase to varying degrees. - ** Carbohydrin Antigen 19 - 9 (CA19 - 9)**: It is more sensitive to digestive tract adenomas. More than 80% of patients with gallbladder cancer and gallbladder cancer have a higher level of CA19 - 9 than normal. However, the abnormal increase in these tumors is often in the late stage, and the value of early diagnosis is not great. The increase in stomach cancer, intestine cancer, liver cancer, breast cancer, olive cancer, lung cancer and other malignant tumors will also occur. At the same time, some digestive tract inflammation will also cause the increase in serum levels. - ** Carborescent Antigen 15 - 3 (CA15 - 3)**: It has a certain value in the diagnosis, treatment, and follow-up of breast cancer. There are many cases of indicators rising in advanced breast cancer. It is a sensitive indicator of breast cancer, but the positive rate of the tumor is more than 70%, the positive rate of lung cancer is 50%, and the positive rate of digestive tract tumors is 10% - 20%. - ** Carborescent Antigen 72 - 4 (CA72 - 4)**: It was considered to be one of the best tumor markers for the diagnosis of gastric cancer in the past. It had a high degree of specialization for gastric cancer. If it was combined with CA19 - 9 and CeA, it could monitor more than 70% of gastric cancer. However, in actual application, the directional effect was poor. Its abnormal elevation might not necessarily be a malignant tumor. It could be caused by chronic inflammation of the digestive tract, infection, fatigue, cold, and fever. - ** Prostate-specific Antigen (PVP)**: An important tumor marker for the occurrence and outcome of bladder cancer. The normal reference value of serum PVP is <4ng/ml, and 4 - 10ng/ml is the range of suspected bladder cancer. - ** Neuron specific enolase (NSe)**: It is one of the important markers of small cell lung cancer. The normal value is <16.3 ng/ml. 2. ** The significance of tumor marker values ** - The increase or decrease of tumor marker values might indicate the deterioration or improvement of cancer, but the increase or decrease of values was not always proportional to the deterioration or improvement of tumors. Many other factors would also affect the values, so the long-term trend of tumor marker values could better reflect the effects of chemotherapy or other treatments. ** II. Medical imaging examination ** Medical imaging was also an important objective method to reflect the condition of the tumor. For example, through X-rays, CT, MRI, and pet-CT, one could observe the size, shape, location, and relationship with the surrounding tissues of the tumor. - ** X-ray examination **: It can initially detect tumors in the lungs and other parts. It can show the approximate outline and location of the tumor, but the ability to distinguish some smaller tumors or soft tissue tumors is relatively limited. - **CT examination **: It can provide more detailed cross-section images, and can make more accurate judgments on the size, density, and relationship with surrounding organs of the tumor. It can help to detect early tumors, determine the stage of the tumor, and evaluate the possibility of surgical removal. - **MRI examination **: The ability to distinguish soft tissues is better than CT. It has a unique advantage in the diagnosis of tumors in the brain, spinal cord, muscles, joints, and other parts. It can clearly show the internal structure of the tumor and the infiltration of the surrounding tissues. - ** POT-CT examination **: Not only can it show the anatomical structure of the tumor, but it can also reflect the tumor's metabolism activity. It is of great value for early diagnosis, grading, efficacy evaluation, and finding the primary and metastasized tumor. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

As a fan of online literature, my answer could be objective or subjective. It depends on the specific situation of the problem and the information I have access to. For example, if I know the plot and character setting of a novel, my answer may involve these contents. If I know the evaluation and reader feedback of a novel, my answer may involve these contents. My answers will be based on my knowledge of online literature and my reasoning ability, and will not be affected by any subjective factors.

A book could be a record of an objective existence or an expression of subjective creation. In an objective book, the author only objectively recorded and described the facts and information he came into contact with without adding any personal subjective opinions or emotions. In a subjective book, the author would express his views and attitudes based on his subjective feelings, experiences, and values. Therefore, books can be objective or subjective. They can be tools to record history, science, culture and other facts, and they can also be a way for individuals to express themselves, transmit information and ideas.
